## Generalize Snarf Tool: How The General Can Be Simpler Than The Specific

## 1 Executive Summary

The previous article detailed the implementation of a simple function that lets you snarf the contents within a pair of delimiters. That version handled a set of generic delimiters, and errored out if point was not on one of the pre-defined delimiters.

This article shows how that solution can be generalized to cases where point is not on a pre-defined delimiter; in the process, it weighs the pros and cons of usability vs over-generality and shows an implementation that attempts to strike a good balance.

## 2 The Updated Implementation

    (defun snarf-sexp
          (&optional delete)
          "Snarf the
          contents between delimiters at point.
          Optional interactive
          prefix arg deletes it."
          (interactive "P")
          (let
          ((orig (point))
          (pair nil)
          (pairs ;;;
          We keep
          predefined pairs for usability:
          '((?< ?>)
          (?\[ ?\])
          (?\( ?\))
          (?{ ?})
          (?\" ?\")
          (?' ?')
          (?` ?')
          (?| ?|)
          (?* ?*)
          (?/ ?/)
          (?- ?-)
          (?_ ?_)
          (?~ ?~)))
          (char (char-after))
          (stab nil))
          (setq
          pair ;;;
          But we
          read a close delimiter  for the general case
          (or (assq
          char pairs) ;;;
          Predefined delimiter
          (list char (read-char "Close Delimiter: "))))
          ;;;
          Generality!
          (setq
          stab (copy-syntax-table))
          (with-syntax-table stab
          (cond
          ((= (cl-first pair) (cl-second pair))
          (modify-syntax-entry (cl-first pair) "\"" )
          (modify-syntax-entry (cl-second pair) "\"" ))
          (t
          (modify-syntax-entry (cl-first pair) "(")
          (modify-syntax-entry (cl-second pair) ")")))
          (save-excursion
          (forward-sexp)
          (cond
          (delete
          (kill-region (1+ orig) (1- (point))))
          (t (kill-ring-save (1+ orig) (1- (point)))))))))

## 3 Key Takeaways

1. The generalized implementation no longer throws an error if point is not on a pre-defined delimiter.
2. Instead, it generalizes the implementation to read the close delimiter from the keyboard if char at point is not in the pre-defined list.
3. We could generalize further by entirely dropping the pre-defined delimiters, but that would hurt usability in the common case where the user would always have to specify the close delimiter.
4. Note that usability here is not merely to reduce a keystroke; it's more to reduce the cognitive load on the user with respect to having to think about the close delimiter in the common case.

## Snarfing String Within Delimiters With One Defun

## 1 Executive Summary

I found that I frequently needed to snarf a string enclosed within delimiters, e.g., URLs in email messages <url>, bolded, italics and other styled text in org-mode etc. I first tried package ciel but found that it did not handle all the delimiters I wanted. However looking into it further revealed that emacs had all the tools needed to reduce the task to a single defun!

## 2 The Solution

Here is the solution I implemented at emacspeak-wizards-snarf-sexp. invoking this command with point on the opening delimiter snarfs the enclosed string into the kill-ring; an optional prefix arg clears it as well. The code below is the same as in the Emacspeak project, but with emacspeak-specific calls removed:

    (defun snarf-sexp-contents (&optional
          delete)
          "Snarf the
          contents between delimiters at point.
          Optional interactive
          prefix arg deletes it."
          (interactive "P")
          (let
          ((orig (point))
          (pair nil)
          (pairs ;;;
          The
          delimiter pairs:
          '((?< ?>)
          (?\[ ?\])
          (?\( ?\))
          (?{ ?})
          (?\" ?\")
          (?' ?')
          (?` ?')
          (?| ?|)
          (?* ?*)
          (?/ ?/)
          (?- ?-)
          (?_ ?_)
          (?~ ?~)))
          (char (char-after))
          (stab nil)) ;;;
          Syntax
          table we  use
          (unless
          (setq
          pair (assoc char pairs)) ;;; Not on a delimiter
          (error
          "Point is not on
          a supported delimiter"))
          (setq
          stab (copy-syntax-table))
          (with-syntax-table stab
          (cond
          ((= (cl-first pair) (cl-second pair)) ;;;Like quotes
          (modify-syntax-entry (cl-first pair) "\"" )
          (modify-syntax-entry (cl-second pair) "\"" ))
          (t;;;
          Like
          parens
          (modify-syntax-entry (cl-first pair) "(")
          (modify-syntax-entry (cl-second pair) ")")))
          (save-excursion;;; We have our sexp
          (forward-sexp) ;;;
          Will
          error out if delims dont match
          (cond
          (delete ;;;
          Clear
          sexp contents
          (kill-region (1+ orig) (1- (point))))
          (t ;;;
          Copy sexp
          contents
          (kill-ring-save (1+ orig) (1- (point)))))))))

### 2.1 Key Take-Aways

- S-expressions are a key Emacs concept with extensive built-in support.
- S-expressions are determined by matching delimiters.
- Delimiters are defined by the syntax-table in effect.
- Emacs-lisp primitives let us define and manipulate temporary syntax-tables.
- Putting it all together, the underlying task of snarfing the contents within a pair of delimiters reduces to a few calls to the underlying primitives.

## Contextual Context Switching For An Efficient Workflow

## 1 Executive Summary

Context switching in an Emacs workflow comes down to switching buffers — and Emacs provides a large number of built-ins and extensions packages for switching buffers. One can put together numerous workflows by picking among these to make context switching contextual — using the most appropriate workflow can lead to being able to focus much better on the core task of creating, editing, reviewing and publishing all forms of content ranging from research papers and presentations to Open Source Software.

This article summarizes my present workflow — it's entirely keyboard driven and optimized for an eyes-free workflow.

## 2 Where Does Context Come From?

Context as used in this article can be traced back to the current task at hand — here are some illustrative examples:

1. Editing a set of related files. (.c, .h)
2. Switching among a collection of chat buffers. (major-mode)
3. Switching among a collection of mail folders. (major-mode)
4. Switching among a collection of open Web pages. (major-mode)
5. Switching among a small number of recently used buffers. (recency)
6. Switching among buffers in the same project (project)
7. Switching between project-specific shells and buffers. (project)

## 3 Building Blocks For Context Switching

Here are some of the building blocks I use to construct workflows that meet the use-cases enumerated in the previous section. Many of these are built into Emacs; some come from extra packages and a few are implemented in Emacspeak to fill the gaps. See the related article Search, Input, Filter, Target (SIFT) interaction described in a previous article for a more detailed explanation or properties that characterize effective eyes-free interaction.

1. Built-in Command `next-buffer` and `previous-buffer` bound to `hyper-,` and `hyper-.`.
2. Builtin Command ~ `other-window` bound to `C-x o`.
3. Emacspeak Commands `emacspeak-wizards-cycle-to-next-buffer` and `emacspeak-wizards-cycle-to-previous-buffer` bound to `Alt-n` and `Alt-p`.
4. Emacspeak Command `emacspeak-wizards-shell-toggle` bound to `Super-,`.
5. Emacspeak Command `emacspeak-wizards-shell-by-key` bound to `C-c [1-9]`.

### 3.1 Things To Note

1. Notice that many of these commands come in pairs and use key-bindings that also pair-up with respect to muscle memory; over time I have found this type of pairing to be essential for them to become part of one's daily habit.
2. And when these task-specific commands dont get you the buffer you want with one or two keystrokes, one can always fallback to `switch-to-buffer`.
3. Built-in Command `switch-to-buffer` bound to `C-x b` which in my environment maps to `ido-switch-buffer` with fuzzy completion.

### 3.2 Related Packages

There are of course many alternatives to the building blocks above, here is a non-exhaustive list:

- Package `helm` with `ivy`, `counsel` and friends.
- Package `selectrum`.

- Additionally organizing one's workspace using `Emacs Frames` with each frame dedicated to tasks like email — visual workspaces.

  In general, I've not found any of the above adding much in the context of eyes-free interaction.

## 4 Conclusion

Emacs has a large number of facilities that lend themselves to multiple workflows. Investing some time in putting together workflows that suit one's needs has a large pay-back over time.

## Announcing Emacspeak 54.0 (EZDog)

# Announcing Emacspeak 54.0—EZDog!

The enjoyment of one's tools is an essential ingredient of successful work. – Donald E. Knuth

## 1 For Immediate Release:

San Jose, CA, (May 3, 2021)

### 1.1 Emacspeak 54.0 (EZDog) Unleashed! 🦮

— Making Accessible Computing EZ Again!

Advancing Accessibility In The Age Of User-Aware Interfaces — Zero cost of Ownership makes priceless software Universally affordable!

Emacspeak Inc (NASDOG: ESPK) — http://github.com/tvraman/emacspeak announces immediate world-wide availability of Emacspeak 54.0 (EZDog) 🦮 — a powerful audio desktop that leverages today's evolving Data, Social and Assistant-Oriented Internet cloud to enableworking efficiently and effectively from anywhere!

## 2 Investors Note:

With several prominent tweeters expanding coverage of #emacspeak, NASDOG: ESPK has now been consistently trading over the social net atlevels close to that once attained by DogCom high-fliers—and as of May 2021 is trading at levels close to that achieved by once better known stocks in the tech sector.

## 3 What Is It?

Emacspeak is a fully functional audio desktop that provides complete eyes-free access to all major 32 and 64 bit operating environments. By seamlessly blending live access to all aspects of the Internet such as ubiquitous assistance, Web-surfing, blogging, remote software development, social computing and electronic messaging into the audiodesktop, Emacspeak enables speech access to local and remote information with a consistent and well-integrated user interface. A rich suite of task-oriented tools provides efficient speech-enabled access to the evolving assistant-oriented social Internet cloud.

## 4 Major Enhancements:

1. Faster Startup 🛱
2. MP3 Files In Dired 🎹
3. Dynamic playlist support with m-player 🎶
4. Gopher And Gemini ♊
5. Emacs 28 with native compilation 🚅
6. Updated Soundscapes 🐦
7. Updated wizards🧙
8. Updated URL templates 🕷
9. Capitalization And AllCaps 💼

10. Updated keymaps and keybindings ⌨

    — And a lot more than will fit this margin. … 🗞

Note: This version requires emacs-27.1 or later.

## 5 Establishing Liberty, Equality And Freedom:

Never a toy system, Emacspeak is voluntarily bundled with all major Linux distributions. Though designed to be modular, distributors have freely chosen to bundle the fully integrated system without any undue pressure—a documented success for the integrated innovation embodied by Emacspeak. As the system evolves, both upgrades and downgrades continue to be available at the same zero-cost to all users. The integrity of the Emacspeak codebase is ensured by the reliable and secure Linux platform and the underlying GIT versioning software used to develop and distribute the system.

Extensive studies have shown that thanks to these features, users consider Emacspeak to be absolutely priceless. Thanks to this wide-spread user demand, the present version remains priceless as ever—it is being made available at the same zero-cost as previous releases.

At the same time, Emacspeak continues to innovate in the area of eyes-free Assistance and social interaction and carries forward the well-established Open Source tradition of introducing user interface features that eventually show up in luser environments.

On this theme, when once challenged by a proponent of a crash-prone but well-marketed mousetrap with the assertion "Emacs is a system from the 70's", the creator of Emacspeak evinced surprise at the unusual candor manifest in the assertion that it would take popular idiot-proven interfaces until the year 2070 to catch up to where the Emacspeak audio desktop is today. Industry experts welcomed this refreshing breath of Courage Certainty and Clarity (CCC) at a time when users are reeling from the Fear Uncertainty and Doubt (FUD) unleashed by complex software systems backed by even more convoluted press releases.

## 6 Independent Test Results:

Independent test results have proven that unlike some modern (and not so modern) software, Emacspeak can be safely uninstalled without adversely affecting the continued performance of the computer. These same tests also revealed that once uninstalled, the user stopped functioning altogether. Speaking with Aster Labrador, the creator of Emacspeak once pointed out that these results re-emphasize the user-centric design of Emacspeak; “It is the user — and not the computer– that stops functioning when Emacspeak is uninstalled!”.

### 6.1 Note from Aster,Bubbles and Tilden:

UnDoctored Videos Inc. is looking for volunteers to star in a video demonstrating such complete user failure.

## 7 Obtaining Emacspeak:

Emacspeak can be downloaded from GitHub — see https://github.com/tvraman/emacspeak you can visit Emacspeak on the WWW at http://emacspeak.sf.net. You can subscribe to the emacspeak mailing list — emacspeak@emacspeak.org. The Emacspeak Blog is a good source for news about recent enhancements and how to use them.

## Emacspeak 53.0 EfficientDog Unleashed!

# Announcing Emacspeak 52.0—WorkAtHomeDog!

The enjoyment of one's tools is an essential ingredient of successful work. – Donald E. Knuth

## 1 For Immediate Release:

San Jose, CA, (Nov 22, 2020)

### 1.1 Emacspeak 53.0 (EfficientDog) 🦮 Unleashed!

— Making Telecommuting Fun Again!

Advancing Accessibility In The Age Of User-Aware Interfaces — Zero cost of Ownership makes priceless software Universally affordable!

Emacspeak Inc (NASDOG: ESPK) — http://github.com/tvraman/emacspeak — announces the immediate world-wide availability of Emacspeak 53.0 (EfficientDog) 🦮 — a powerful audio desktop that leverages today's evolving Data, Social and Assistant-Oriented Internet cloud to enable working efficiently and effectively from anywhere!

## 2 Investors Note:

With several prominent tweeters expanding coverage of #emacspeak, NASDOG: ESPK has now been consistently trading over the social net atlevels close to that once attained by DogCom high-fliers—and as of Nov 2020 is trading at levels close to that achieved by once better known stocks in the tech sector.

## 3 What Is It?

Emacspeak is a fully functional audio desktop that provides complete eyes-free access to all major 32 and 64 bit operating environments. By seamlessly blending live access to all aspects of the Internet such as ubiquitous assistance, Web-surfing, blogging, remote software development, social computing and electronic messaging into the audiodesktop, Emacspeak enables speech access to local and remote information with a consistent and well-integrated user interface. A rich suite of task-oriented tools provides efficient speech-enabled access to the evolving assistant-oriented social Internet cloud.

## 4 Major Enhancements:

This version requires emacs-26.1 or later.

1. Speech-Enabled Haskell Mode ⁡
2. Speech-Enable VTerm 🖳
3. Speech-Enable Package Syslog
4. Speech-enable Package hide-lines 𐇪
5. Speech-Enable Racer 🖹
6. Speech-Enable Eglot 󠀁
7. speech-Enable project.el 📽
8. Speech-Enable rust-mode 🦊
9. Emacspeak-sdcv — speech-Enable Stardict Interaction 🤩
10. Add CTL-Z As A New Prefix Keymap ⌨

— And a lot more than will fit this margin. … 🗞

## 5 Establishing Liberty, Equality And Freedom:

Never a toy system, Emacspeak is voluntarily bundled with all major Linux distributions. Though designed to be modular, distributors have freely chosen to bundle the fully integrated system without any undue pressure—a documented success for the integrated innovation embodied by Emacspeak. As the system evolves, both upgrades and downgrades continue to be available at the same zero-cost to all users. The integrity of the Emacspeak codebase is ensured by the reliable and secure Linux platform and the underlying GIT versioning software used to develop and distribute the system.

Extensive studies have shown that thanks to these features, users consider Emacspeak to be absolutely priceless. Thanks to this wide-spread user demand, the present version remains priceless as ever—it is being made available at the same zero-cost as previous releases.

At the same time, Emacspeak continues to innovate in the area of eyes-free Assistance and social interaction and carries forward the well-established Open Source tradition of introducing user interface features that eventually show up in luser environments.

On this theme, when once challenged by a proponent of a crash-prone but well-marketed mousetrap with the assertion "Emacs is a system from the 70's", the creator of Emacspeak evinced surprise at the unusual candor manifest in the assertion that it would take popular idiot-proven interfaces until the year 2070 to catch up to where the Emacspeak audio desktop is today. Industry experts welcomed this refreshing breath of Courage Certainty and Clarity (CCC) at a time when users are reeling from the Fear Uncertainty and Doubt (FUD) unleashed by complex software systems backed by even more convoluted press releases.

## 6 Independent Test Results:

Independent test results have proven that unlike some modern (and not so modern) software, Emacspeak can be safely uninstalled without adversely affecting the continued performance of the computer. These same tests also revealed that once uninstalled, the user stopped functioning altogether. Speaking with Aster Labrador, the creator of Emacspeak once pointed out that these results re-emphasize the user-centric design of Emacspeak; “It is the user — and not the computer– that stops functioning when Emacspeak is uninstalled!”.

### 6.1 Note from Aster,Bubbles and Tilden:

UnDoctored Videos Inc. is looking for volunteers to star in a video demonstrating such complete user failure.

## 7 Obtaining Emacspeak:

Emacspeak can be downloaded from GitHub — see https://github.com/tvraman/emacspeak you can visit Emacspeak on the WWW at http://emacspeak.sf.net. You can subscribe to the emacspeak mailing list — emacspeak@cs.vassar.edu — by sending mail to the list request address emacspeak-request@cs.vassar.edu.

## Web: Data Tables Can Be More Than Screen-Deep

## 1 Executive Summary

A few years ago, layout tables made speaking Web content difficult; that phase has now morphed into an even more horrifying soup of `div` and `span` tags styled by CSS. This also means that now, if you encounter a `table` element, it likely contains some useful data; also, deeply nested tables are beginning to feel like a thing of the past.

Sadly, this has not made getting data out of HTML tables any easier. A combination of badly created markup, many redundant DOM nodes that exist purely for enabling DOM scripting, and heavy-weight DOM structures that result from code-generation have mostly created a different, but equally appalling situation .

One of the primary reasons to do everything in a rich end-user environment like Emacs is the ability to share data across tasks and being able to manipulate data as data, rather than working with that data's underlying visual representation. Emacs can now render Webdocuments that are content focused, so the next immediate desire is to be able to extract data in a useful form from EWW rendered pages. This article describes one simple approach that lets me turn HTML tables found in the wild into a coherent tabular data structure that I can access meaningfully via emacspeak to obtain multiple spoken views of the data.

## 2 Initial Approach That Failed

I first tried to see if I could make EWW annotate the rendered table data with text properties — sadly that proved impossible to do in the current implementation. Note however that Emacspeak does use textproperties to provide access to other aspects of HTML document structure such as section headers, and moving through the rendered tables in an EWW buffer.

## 3 Ensuring That EWW Rendered Tables Are More than Screen-Deep

I implemented the approach described below a couple of weeks ago and it appears to work well barring a few known limitations.

1. I advice EWW to store a pointer to the Table DOM in the EWW buffer.
2. I defined a function that converts the DOM nodes from the table-dom into a two-dimensional vector.
3. I then pass this structure to Emacspeak's Table-UI module to obtain a browsable two-dimensional structure.
4. Module emacspeak-table-ui enables the user to obtain multiple spoken views of the tabular data.

See the following sections for details on each of these steps.

### 3.1 Storing A Pointer To The Table-DOM

    (defadvice shr-tag-table-1
          (around emacspeak pre act comp)
          "Cache pointer to
          table dom as a text property"
          (let
          ((table-dom (ad-get-arg 0))
          (start (point)))
          ad-do-it
          (unless
          (get-text-property start 'table-dom)
          (put-text-property start (point)
          'table-dom table-dom))
          ad-return-value))

This advice stores a pointer to the DOM of the table being rendered over the region containing the rendering.

### 3.2 Generate A Tabular Structure From The Dom

Function `emacspeak-eww-table-table` generates a two-dimensional vector that encaspulates the tabular data.

    (defun emacspeak-eww-table-table ()
          "Return table
          cells as a table, a 2d structure."
          (let*
          ((data nil)
          (table (get-text-property (point) 'table-dom))
          (head (dom-by-tag table 'th)))
          (cl-assert table t "No table
          here.")
          (setq
          data          (cl-loop
          for r in (dom-by-tag table 'tr) collect
          (cl-loop
          for c in
          (append
          (dom-by-tag r 'th)
          (dom-by-tag r 'td))
          collect
          (string-trim (dom-node-as-text c)))))
          ;;;
          handle
          head case differently:
          (if head
          (apply #'vector (mapcar #'vconcat  (cdr data)))
          (apply #'vector (mapcar #'vconcat  data)))))

The above code handles the case where there are header (i.e., th) cells specially to avoid a bug where we get two copies of the data. The nested loops generates a list of lists, and the final call turns this into a two-dimensional vector.

### 3.3 Browsing Tables As Data

Interactive command `emacspeak-eww-table-data` (bound to C-t) takes the table at point, i.e. when point is anywhere within a table rendering, and creates a browsable table buffer as implemented by module emacspeak-table-ui.

    (defun emacspeak-eww-table-data ()
          "View  table at
          point as a data table using Emacspeak Table UI."
          (interactive)
          (let
          ((data (emacspeak-eww-table-table))
          (data-table nil)
          (inhibit-read-only  t)
          (buffer
          (get-buffer-create
          (format  "Table:
          %s" (emacspeak-eww-current-title)))))
          (setq
          data-table (emacspeak-table-make-table data))
          (emacspeak-table-prepare-table-buffer data-table buffer)))

The two-dimensional vector described earlier is now converted to a tabular structure as expected by module `emacspeak-table-ui`, the primary difference being that this structure explicitly captures row and column headers.

### 3.4 Browsing The Tabular Data

Emacspeak's Table UI allows one to:

1. Move through table cells, either by row or column.
2. Determine what is spoken during such navigation,
3. Spoken views can include cell value, row header and column header.
4. For more advanced use-cases, one can define a row filter or column filter, think of these as specialized formatters that can format selected cells and their headers into a natural-sounding sentence.

## Extracted A Light-Weight Key-Reader By Progressive Simplification

# Extracting A Light-Weight Key-Sequence Reader By Progressive Simplification

## 1 Background

In the previous article entitled On Defining Keys In Emacs I covered the issue of declaring key-sequences when defining keyboard short-cuts. During the last week, I took the underlying Emacs Lisp function `edmacro-parse-key` and via a process of progressive simplification derived a new `new-kbd` function that is much simpler and consequently easier to understand. You can see the step-by-step simplification via the Git history for file new-kbd.el (note: used to be called `ems-kbd.el`). That file contains the final version of the simplified function, along with a test-suite that verifies that it's behavior is convenient with the solution built into Emacs. The updated function is now part of Emacspeak and is named `ems-kbd` in that package.

The next section gives a high-level overview of the steps that led tothe final version.

## 2 Steps Toward Simplification

### 2.1 Separate Tokenization From Processing

Function `edmacro-parse-keys` interweaves the process of tokenizing its input string and how various parts of that string are processed in a single `while` loop.

The first step in simplification was to separate these steps, by using function `split-string` to split the input string on whitespace to generate a list of words.

A simple `cl-loop` is then used to turn each `word` into a `key` that is accumulated into a result vector.

### 2.2 Refactoring Case Analysis

Once tokenization is factored out, the remainder of function `edmacro-parse-keys` converts each key-specification into either the corresponding string or vector representation.

The original requirement of parsing the serialization of keyboard-macros brought along additional logic that I first eliminated, since my goal was to create a function to be used in defining keyboard-shortcuts.

- I eliminated code that handled invocation of `M-x execute-extended-command` during a keyboard-macro.
- I eliminated processing of comments within the keyboard-macro serialization.

### 2.3 Rearranging Conditionals

Next, I rearranged conditionals and in that process eliminated `cond` clauses that were now effectively dead-code.

In the process, I also eliminated test-predicates that had side-effects to hopefully result in less fragile code.

### 2.4 Lexically Bind Regex Patterns

To improve readability, I created let-bindings to some of the regex patterns used to identify key-sequence patterns. In the process, I also made these more readable by using [:space:] for white-space tests.

### 2.5 Always Return A Vector

Finally, I setup the new function to always return a vector; function`edmacro-parse-keys` returns either a string or a vector based on how it is called. Since Emacs now takes a vector in every context where a key-sequenceis expected, this simplification does not break when using our simplified function for defining keys.

       (defun new-kbd
          (string )
          "Simplified and hopefully more robust kbd function.
          Always returns a vector i.e. like passing need-vector to
          edmacro-parse-keys. "
          (let ((res [])
          (special-char-reg
          "^\\(NUL\\|RET\\|LFD\\|ESC\\|SPC\\|DEL\\)$")
          (modifier+angle-reg
          "^\\(\\([ACHMsS]-\\)*\\)<\\(.+\\)>$"))
          (cl-loop
          for word in (split-string string)
          do

          (string-match modifier+angle-reg word))
          (setq key

          (intern
          (concat ;;; strip < and >
          (substring word (match-beginning 1) (match-end 1))
          (substring word (match-beginning 3) (match-end 3)))))))
          (t

          ((= bits 0) (setq key word))
          ((/= (length word) 1)
          (error "%s: Prefix  must precede a single character, not
          %s"
          string word))
          ((and
          (/= (logand bits ?\C-\^@) 0)
          (string-match "[@-_a-z]" word))
          (setq key
          (list (+ bits (- ?\C-\^@)
          (logand (aref word 0) 31)))))
          (t (setq key (list (+ bits (aref word 0)))))))))
          ;;; push key on to the result vector
          (when key (cl-callf vconcat res key))))
          res))

You can verify the code above by running the tests found at the end of file `new-kbd.el` — the tests were extracted from the various patterns described in the Elisp Reference, as well as by reading thecode in `edmacro-parse-keys`.

### 2.6 Closing Thoughts

The above simplification exercise was done by:

1. Starting with the original `edmacro-parse-keys` copied over to a new file and renamed to function `new-kbd`.
2. Adding a set of tests at the end of file, essentially this is a `let` that binds a set of tests, then compares the result of calling our new function on each value with that returned by the original.
3. Modifying and simplifying our new function and running `eval-buffer` after each step.
4. It was a fun exercise to see order emerge from chaos at each step!

## On Defining Keys In Emacs

## 1 Overview

Emacs is extremely flexible with respect to letting you bind keys to commands. Interestingly, and perhaps because of its history tracing back to keyboard macros, naming the key you wish to bind is not so straight-forward as it appears on the surface. Here are things I've used and learnt over the last 30 years of Emacs hackery:

1. The most basic way of naming a key is via a string of the form \C-a or \M-\C-a where \C denotes the Control Modifier.
2. This notation gets unwieldy fast when using multiple modifiers as in the \M-\C-a example.
3. It gets worse, under X, you can bind \C- / for /Control Space — notice that the space character here which is easy to miss as white-space is significant.
4. The \<modifier>-char notation mostly appears to date back to the age of the terminal emulator (tty), so for example, it cannot denote Control+Right for example.
5. The Emacs and Elisp info manuals recommend using function kbd for this reason, this function on the surface provides a unified interface for naming keys.

If you look no further, you remain happy, but …

## 2 Function `kbd`

But if you do peel the onion, here is what you find:

1. Function `kbd` does nothing more than calling function `read-kbd-macro`.
2. Function `read-kbd-macro` documents itself as reading the region as a keyboard macro.
3. The above overloading is achieved by the call to function `edmacro-parse-keys`.
4. And finally we reach the scary core of the onion that is sufficient to make your eyes water!
5. Function `edmacro-parse-keys` is an inscrutable piece of code that both looks extremely clever and magical and like all clever code, feels fragile.

## 3 Understanding And (Hopefully) Simplifying Function `kbd`

A simplified `ems-kbd` function that is free from the complexity resulting from reading in a saved keyboard macro feels like a worthwhile goal. I started down this road both to understand function `edmacro-parse-keys` — sadly, I haven't yet found a specification for naming all available keys outside of the implementation of that function. So I started ems-kbd.el along with a simple test-suite to see how far I could get toward the goal of creating an equivalent `kbd` function.

### 3.1 Steps So Far

1. Documented the implementation.
2. Added a simple set of tests in the file.
3. Changed if to cond or when as appropriate.
4. Eliminated the logic that handled the keyboard macro serialization for repeated keys.
5. Removed the logic for handling invocations of `execute-extended-command` — otherwise known as M-x.
6. A lot more remains, e.g.,
   - simplifying how modifier bits are handled,
   - Simplifying how special patterns like SPC or TAB are handled.
   - And likely a lot more.

An alternative approach might be to rewrite it from scratch, but thatfeels intractable unless I can track down a specification for naming keys that is exhaustive with respect to the various conventions thathave been used over the years.

## Searching GMail From GNUS

# Using GMail Search Operators In GNUS

## 1 Executive Summary

I have been using the following to search GMail from GNUS for over 8 years now. The recent announcement of the nnselect back-end reminded me that I had never gotten to writing this up formally, So here goes. With the described solution in place, you can search your GMail from within GNUS using the same GMail Search operators that you're familiar with from within your Web Browser, e.g. searches of the form from: foo, subject:bar, after:date and combinations of the above.

## 2 Background

You can read email with GNUS, and many people read GMail with GNUS, however, the details of GMail setup with GNUS wont fit this margin. For my own GMail setup using Ceasar's excellent auth-xoauth2 package, see filegnus-gmail-prepare.el.

## 3 Leveraging GNUS Back-end NNIR To Search GMail

GMail is accessed from GNUS using the imap protocol. The imap specification defines a set of standard search operators; GMail itself defines a slightly different and arguably easier to use set of search operators. Module gm-nnir himplements both the standard IMap search operator as well as GMail's search operators; in practice, I have mostly only used the GMail Search operators in the last 8 years since implementing this module.

Without further ado, here is the code to enable GMail Search:

    (defun
          gm-nnir-group-make-gmail-group (query)
          "Use GMail search syntax.
          See https://support.google.com/mail/answer/7190?hl=en for syntax.
          "
          (interactive "sGMail Query: ")
          (let ((nnir-imap-default-search-key "imap")
          (q (format "X-GM-RAW \"%s\"" query)))
          (cond
          ((gnus-group-group-name)           ; Search current group
          (gnus-group-make-nnir-group
          nil                              ; no extra params needed
          `(nnir-specs (nnir-query-spec (query ,q)))))
          (t (error "Not on a group.")))))

I bind the above to / by using

    (define-key
          gnus-group-mode-map "/"
          'gm-nnir-group-make-gmail-group)

## 4 Example Of Use

I am subscribed to list emacs-devel@gnu.org and email sent to that list gets GMail Label `emacs-devel`. In Gnus, I open that label as group `emacs-devel@gnu.org`. Typing / on the group line and entering

          from:rms after:2020/09/01

in the minibuffer results in the following:

          1.1 Re: Good first issues to contribute Richard Stallman 05-Sep
          [5.3k]
          2.1 Lars Ingebrigtsen is now one of the Emacs maintainers Richard
          Stallman 06-Sep [4.9k]
          3.1 Re: A new user perspective about "Changes for emacs
          28"      Richard Stallman 07-Sep [5.5k]
          4.5 Re: Changes for emacs 28 Richard Stallman 07-Sep [5.3k]
          5.1  Richard Stallman 07-Sep <6.2k>
          6.1  Richard Stallman 07-Sep <6.0k>
          7.1  Richard Stallman 07-Sep <5.5k>
          8.1  Richard Stallman 07-Sep <5.7k>

The search above creates an ephemeral group with matching messages appearing as shown above, you can read messages, reply to them and do anything else that you might ordinarily do within the GNUS interface.

## Start Emacs In A Defun

## 1 Summary

This is a follow-up to my earlier article titled Speeding Up Emacs Startup from August 2017. Three years later, I once again spent time cleaning up and refactoring the results as described below. The end-result is to once again speed up Emacs startup, (about 25% faster on my laptop)while making the setup cleaner and easier to maintain than before.

## 2 Start Emacs In A Defun

This startup file is set up with the following goals:

1. Speed up emacs startup — setting environment variable`TVR_TIME_EMS` before starting emacs produces detailed timing information in the Messages buffer.
2. Customize packages via Custom as far as possible.
3. Keep the custom settings in a separate file, with a later goal of turning that into a theme.
4. After converting to a theme, Move machine-specific custom settings into a separate host-specific custom file, thus making the earlier theme host-independent. Place host-specific non-customizable bits in default.el (not done yet).
5. Define package-specific settings not available via Custom in a package-specific <package>-prepare.el file.
6. Install everything from elpa/melpa as far as possible. (vm is anexception at present) — I have nearly 200 packages activated.
7. The startup file is a collection of functions with entry-point tvr-emacs.
8. The only top-level call is (tvr-emacs).
9. Function tvr-emacs starts up Emacspeak, and sets up two hooks:
   - after-init-hook to do the bulk of the work.
   - emacs-startup-hook to set up initial window configuration.
10. Function tvr-after-init-hook on after-init-hook does the following:
    - Load package-specific prepare.el files.
    - Load the custom settings file.
    - Starts up things like the emacs server.
    - Some of these tasks are done on a separate thread using make-thread.
11. The work of loading files etc., is done within macro tvr-fastload

which sets up an efficient environment for loading files.

## 3 Conclusion

With this setup, `M-x emacs-init-time` shows init-time as

          1.288381225 seconds

on my laptop with an SSD. Setting `package-quickstart` to `T` is a major win when running with a spinning-disk instead of an SSD. But the biggest win is that I no longer have to go hunting to find out where something in emacs got configured a given way — AKA, there are a limited number of places I need to look.

## 4 Wish-List

1. Remembering the name of a custom-setting you set up a while ago is still a challenge, You cant find it unless you remember its approximate name.
2. Command `emacspeak-wizards-customize-saved` bound to `C-h C-s` helps some in this regard but is a stop-gap solution.
3. Custom themes are not easy to use.
4. I keep my `custom-file` checked into a local Git repository and is the only part of my setup that I cannot publish — since thatfile tends to hoover up information that you shouldn't publish, e.g., aPI keys and other private/personal bits.
5. Perhaps Emacs needs at least two custom-files, a public and a private custom-file.

## Learning Rust: Programming The Pick-Up Sticks Game

# Learning Rust: The Pick-Up Sticks Game

## 1 Overview

This directory contains an implementation of the Pick Up Sticks game
described in my paper Thinking Of Mathematics (Section 5).

It's an interesting experience writing it in Rust as I learn the
language. The original implementation described in my paper was
written in 1987 in Fortran-77, and consisted of one single
function. Though that style of programming would be frowned upon today
and is clearly not advisable for programming in the large, it's
interesting to observe that a more structured implementation as seen
in this Rust implementation qrequires a lot more fore-thought with
respect to code organization.

## 2 Programming Environment

here is a short overview of the programming environment used:

1. Emacs 28.0.50 with emacspeak 52.0.
2. Package `eglot` for managing the project with an LSP server.
3. Rust Language Server (RLS) as the LSP server.
4. Package `company` for completion.
5. Package `yasnippet` for code templates.
6. Package `rust-mode` for Rust editing smarts.
7. Package `racer` for additional cross-referencing and
   documentation support.
8. Package `cargo` for cargo integration from inside Emacs.

In the process of setting up my Rust environment, I also
speech-enabled Emacs packages `rust-mode`, `racer` and `cargo` for Emacspeak.

## 3 Books

I downloaded The Rust Programming Language (2018) from Bookshare
and it's what I am still using as I write this. Note that this book is
also available in the Rust distribution. The version in the Rust
distribution is a little less usable since it's split into multiple
smaller HTML files with each file repeating a lot of navigational
boiler-plate at the top.

## 4 Experience Learning Rust

I usually find that I learn a language better if I write some code as
I learn the language.
In this instance, I decided to program the pick-up-sticks game — a
simple game that I programmed in 1987 for the final class project for
CS-101 at IIT-Bombay. Here are the rules of the game:

1. This is a two-player game and the game starts with \(n\) sticks.
2. The first player can pick at most \(n-1\) sticks.
3. Assume a player picks \(k\) sticks. At the subsequent turn, opponent
   can pick at most \(2 * k\) sticks.
4. The player who is able to clean-up the remaining sticks while
   adhering to the rules is the winner.

Read Thinking Of Mathematics (Section 5) for a description of an
algorithm that is guaranteed to win.

## 5 The Implementation

Learning Rust's ownership rules for memory management, and learning to
use references the Rust way were some of the things that were unique
to this learning experience.
Rust has some unique features including declaring lifetimes that are
typically needed in more advanced cases; however in my initial
attempts, not doing things the Rust way caused compile-time errors
that initially guided me toward using and declaring
lifetimes. Eventually, all of those declarations became unnecessary.
More generally, the Rust compiler turns out to be a very good Rust
teacher.

## 6 Crux Of The Implementation

See module `game.rs` for the implementation. The core of the
implementation is still a handful of lines to implement the winning
strategy of:

1. If the number of sticks at the start is a Fibonacci number, ask
   the opponent to play first.
2. At each turn, force the opponent toward the closest Fibonacci number.
3. Do above while respecting the limit rule, i.e. if you pick \(k\)
   sticks, the opponent can pick up to \(2k\) sticks, so never pick \(k\)
   where \(3k >= n\).
4. The result of (3) is to subdivide the game into smaller games
   when playing with larger values of \(n\) — see the while loop in
   method `my_move`.

## 7 Closing Thoughts

1. The computing environment I now have is far more sophisticated
   than what I had in 1987.
2. Today, I have interactive completion, source-code
   cross-references, on-the-fly access to documentation, and a fully
   accessible book where I can look up things whenever I want.
3. In 1987, I did most of my thinking and problem-solving in my
   dorm-room with no computer to hand. When ready with the solution,
   I made a few notes in Braille using a pocket-slate and stylus,
   then went to the computer room with a volunteer reader and typed
   up the program, with the student volunteer providing high-quality
   interactive spoken feedback.
4. Interestingly, I think it took me less time from memory to
   implement the solution in 1987 — perhaps this is time shrinking
   with number of years passed.
5. Either way, the primary take-away is that it pays to analyse a
   problem before one actually starts writing code. Writing code is
   always fun, and today, even more so given the excellent array of
   tools — but unless one focuses on the problem at hand, one can
   spend a lot of time sharpening one's pencils as opposed to
   writing something useful.

## Viewing Data Records As Forms --- Old Is Gold

# Viewing Data Records As Forms: Old Is Gold!

## 1 Executive Summary

Given a file containing data records made up of multiple fields, you
can easily view them using Emacs' `forms` library.

## 2 Background: BBC Program Listings

I use Perl utility `get_player` to fetch details of BBC Radio
programs. When I was using this frequently, I had installed package
`iplayer.el` from Melpa — that package presented the data as a
nicely organized Org document. Time passed, and I somehow stopped
using it, until … last week. Then I discovered that package
`iplayer` on Melpa hadn't been updated in a few years, and worse had
broken because package `org` no longer includes now obsoleted
sub-module `orgstruct`.

## 3 Task: Viewing BBC Program Listings

When I realized package `iplayer` was broken, I tried to make up for
its loss for a few days by using shell-level utilities like `cut`. But
then I missed the convenience of being able to work with the data with
all of Emacs' power and was initially tempted to write a new package
— after all, how hard is it to take a record, split it into fields
and display it in a desired form? Fortunately, I remembered another of
my favorite edicts from the creator of Perl (Larry Wall)

    Lazy
          Programmer Is A Good
          Programmer

At the same time I had a strong sense of dejavu — in the early daysa
of Emacspeak (approx 1995), I remembered demonstrating the power of
Emacs to manipulate and display data records by using file
/etc/passwd as an example.

## 4 The Free Solution

So the completely free (AKA zero-work) solution I used was to leverage
Emacs' built-in `forms` library — the solution
as created
in
get-iplayer.el is below:

    (setq forms-read-only t)
          (setq
          forms-file (expand-file-name "~/.get_iplayer/radio.cache"))
          (setq
          forms-number-of-fields 16)
          (setq
          forms-field-sep "|")
          (setq
          forms-format-list
          (list
          "Id:
          "  1 "\t" "Name: " 3 "\n"
          "Episode:
          " 4 "\t" "Description: "  12
          "\n"))

With the above in place, you can:

1. M-x forms-find-file RET get-iplayer.el
2. This displays one record at a time as specified by `forms-format-list`.
3. You can search through records etc.

## Magit/Forge Cheatsheet For GitHub Workflow

# Magit/Forge Fork And Create Pull-Request Cheat-Sheet For GitHub

The previous article covered the fork/create-pullreq workflow for
GitHub without using a browser.
It turns out that in learning by doing, I had made a few mis-steps
that made things a lot more convoluted. Here is a quick cheat-sheet on
how to do this exclusively with Magit/Forge.

1. Run M-x magit-status on your Git clone of the project to
   which you wish to contribute.
2. Add your GitHub user-id "tvraman" in my case to forge custom
   option forge-owned-accounts.
3. In the magit-status buffer above, type 'cf to create the fork
   and answer the prompts with the defaults as they appear in the minibuffer.
4. Create your feature branch, add your contribution and check-in.
5. In the magit-status buffer, type 'cp to create the
   pull-request.

Share And Enjoy!

## GitHub Standard Fork And Pull-Request Workflow From Emacs

# GitHub Standard Fork And Pull Request From Inside Emacs

## 1 Executive Summary

Collaborating via GitHub (and similar platforms) requires
understanding and following a somewhat standardized fork, create, push
workflow. Most of the gory details of this workflow typically get
hidden by instructions of the form

    Sign in to GitHub in
          your
          browser and /push/ the button on the  top-left

or something similar.
I live exclusively in Emacs and use Chrome as the weapon of
last-resort, this article details how to perform the afore-mentioned
GitHub collaboration workflow from within Emacs. Caveat — you may
still need to resort to Chrome or Firefox to set up GitHub tokens etc.

## 2 The Standard GitHub Workflow

The GitHub collaboration workflow is documented (if somewhat sparsely)
on GitHub, and it's augmented by many excellent tutorials on the
Web. I will avoid repeating that information, other than to link to
them below and point out that reading those is essential to build a
clear mental picture of how things work. The remainder of this article
will focus on how to achieve the equivalent without having to push
buttons on the GitHub web site.

- Tutorial: GitHub Standard Fork & Pull Request Workflow · GitHub
- GitHub Help Pages

## 3 Collecting The Needed Tools

Here are the tools I needed to achieve the goal of achieving the above
workflow from within Emacs and without resorting to a Web browser.

1. Package Magit from Melpa.
2. Package Magit/Forge from Melpa.
3. Command-Line tool hub from GitHub
4. Newer Command-Line tool gh from GitHub.

Command-line tools gh and hub are written in go and implement
the GitHub API.
At the time of writing, hub appears more complete, but gh is
catching up fast.

## 4 Implementing The GitHub Workflow

I'll use a concrete example to avoid introducing additional confusing
terminology. In my own learning journey, I often got confused by
terminology such as name, remote, etc. each of which were being
used in a specialized sense.

### 4.1 Task:

Create a Pull-Request to project speech-rule-engine from user
zorkow/ — the project repository is
Speech Rule Engine from user zorkow.

Fork
  Fork the project you wish to contribute to. I found multiple ways of doing this (eventually).
  1. magit/forge inside emacs:

    'cf RET RET

This invokes command M-x forge-fork which prompts for two name
arguments. The meaning of those arguments are somewhat
non-obvious which is why I failed initially. To use it
successfully, set Forge Custom option forge-owned-accounts to
your GitHub user-id — in my case tvraman. Note that this
variable can hold a list of GitHub user-ids that you use.

    (setq
          forge-owned-accounts
          '(("tvraman")))

With the above in place, go to where you have the source
repository checked out, in my case:

    cd
          ~/sources/zorkow/speech-rule-engine

and open the magit status buffer by executing

    M-x magit-status

and execute Emacs command forge-fork — by default
magit/forge binds this to 'cf. The minibuffer shows the
user-id you set up in forge-owned-accounts/ earlier as the
default, press RET to accept the user-id value for both the
fork and remote arguments.

- The above flow works once it's all set-up — note however that
  if you are happier to just do this at the shell, you can use
  either hub or gh — read the documentation for those
  commands. Either way, you now have a copy of the
  speech-rule-engine project under your list of GitHub
  repositories — in my case at https://github.com/tvraman/speech-rule-engine.

Clone
  Next, git clone the fork you just created. This is just a regular clone operation, in my case I did:

    mkdir -p
          ~/sources/tvraman; cd ~/sources/tvraman; git clone
          https://github.com/tvraman/speech-rule-engine

Create Your Changes
  Follow the steps from the earlier tutorials to do your work, i.e., creating a feature-branch to hold your changes,etc. Note that all this work is being done in your fork, i.e., in this example, within ~/sources/tvraman/speech-rule-engine.
Create Pull Request
  When ready, open the magit-status buffer for your fork, and create the pull-request using magit/forge — in the magit status buffer, type 'cp.
Uploading The Pull Request
  Now, you need to send the pull-request to the author of the project you are contributing to — this is again one of those steps that all the docs talk aboutpushing a button on GitHub.com. The easiest means I found to do this was via command-line tool hub:

    cd
          ~/sources/tvraman/speech-rule-engine; hub pull-request

Assuming you have emacsclient configured as your EDITOR, this opens
a standard commit-like message buffer that lets you complete the
action. Result: a new, shiny pull-request shows up in the target
project — in this case in zorkow/speech-rule-engine.

## Emacspeak 52.0 (WorkAtHomeDog) Unleashed!

# Announcing Emacspeak 52.0—WorkAtHomeDog!

The enjoyment of one's tools is an essential ingredient of successful work. – Donald E. Knuth

## 1 For Immediate Release:

San Jose, CA, (May 4, 2020)

### 1.1 Emacspeak 52.0 (WorkAtHomeDog) 🦮 Unleashed!

— Making Telecommuting Great Again!

Advancing Accessibility In The Age Of User-Aware Interfaces — Zero
cost of Ownership makes priceless software Universally affordable!

Emacspeak Inc (NASDOG: ESPK) — http://github.com/tvraman/emacspeak
— announces the immediate world-wide availability of Emacspeak 52.0
(WorkAtHomeDog) 🦮 — a powerful audio desktop that leverages today's evolving
Data, Social and Assistant-Oriented Internet cloud to enable working
effectively from anywhere!

## 2 Investors Note:

With several prominent tweeters expanding coverage of #emacspeak,
NASDOG: ESPK has now been consistently trading over the social net at
levels close to that once attained by DogCom high-fliers—and as of
May 2020 is trading at levels close to that achieved by once
better known stocks in the tech sector.

## 3 What Is It?

Emacspeak is a fully functional audio desktop that provides complete
eyes-free access to all major 32 and 64 bit operating environments. By
seamlessly blending live access to all aspects of the Internet such as
ubiquitous assistance, Web-surfing, blogging, social computing and
electronic messaging into the audio desktop, Emacspeak enables speech
access to local and remote information with a consistent and
well-integrated user interface. A rich suite of task-oriented tools
provides efficient speech-enabled access to the evolving
assistant-oriented social Internet cloud.

## 4 Major Enhancements:

This version requires emacs-26.1 or later.

1. Emacs 27 Support 🤻
2. Updated URL templates 🕷
3. Updated websearch wizards 🧙
4. Updated EWW support 🕸
5. Speech-enables Emacs Chess ♕ ♔
6. Speech-enables package `Vuiet` for music discovery and playback
   using LastFM 🎼
7. Smart templates for accessing Hacker News ⎔
8. Updated support for Emacs Ipython Notebooks 📓
9. Works fluently with Sage Notebooks

— And a lot more than will fit this margin. … 🗞

## 5 Establishing Liberty, Equality And Freedom:

Never a toy system, Emacspeak is voluntarily bundled with all
major Linux distributions. Though designed to be modular,
distributors have freely chosen to bundle the fully integrated
system without any undue pressure—a documented success for
the integrated innovation embodied by Emacspeak. As the system
evolves, both upgrades and downgrades continue to be available at
the same zero-cost to all users. The integrity of the Emacspeak
codebase is ensured by the reliable and secure Linux platform
used to develop and distribute the software.

Extensive studies have shown that thanks to these features, users
consider Emacspeak to be absolutely priceless. Thanks to this
wide-spread user demand, the present version remains priceless
as ever—it is being made available at the same zero-cost as
previous releases.

At the same time, Emacspeak continues to innovate in the area of
eyes-free Assistance and social interaction and carries forward the
well-established Open Source tradition of introducing user interface
features that eventually show up in luser environments.

On this theme, when once challenged by a proponent of a crash-prone
but well-marketed mousetrap with the assertion "Emacs is a system from
the 70's", the creator of Emacspeak evinced surprise at the unusual
candor manifest in the assertion that it would take popular
idiot-proven interfaces until the year 2070 to catch up to where the
Emacspeak audio desktop is today. Industry experts welcomed this
refreshing breath of Courage Certainty and Clarity (CCC) at a time
when users are reeling from the Fear Uncertainty and Doubt (FUD)
unleashed by complex software systems backed by even more convoluted
press releases.

## 6 Independent Test Results:

Independent test results have proven that unlike some modern (and
not so modern) software, Emacspeak can be safely uninstalled without
adversely affecting the continued performance of the computer. These
same tests also revealed that once uninstalled, the user stopped
functioning altogether. Speaking with Aster Labrador, the creator of
Emacspeak once pointed out that these results re-emphasize the
user-centric design of Emacspeak; “It is the user — and not the
computer– that stops functioning when Emacspeak is uninstalled!”.

### 6.1 Note from Aster,Bubbles and Tilden:

UnDoctored Videos Inc. is looking for volunteers to star in a
video demonstrating such complete user failure.

## 7 Obtaining Emacspeak:

Emacspeak can be downloaded from GitHub — see
https://github.com/tvraman/emacspeak you can visit Emacspeak on the
WWW at http://emacspeak.sf.net. You can subscribe to the emacspeak
mailing list — emacspeak@cs.vassar.edu — by sending mail to the

## Speaking Of Chess: Speech-Enabling Emacs Chess In Emacspeak

## 1 Overview

### 1.1 Research question:

What type of spoken feedback does one need to:

1. Learn Chess.
2. Examine and learn from games.
3. Play effectively.
4. View the state of the game from different perspectives during a game.
5. Provide auditory feedback that is both succinct and maximally informative.
6. Arrive at a spoken notation for speaking various game states
   that is both expressive and time-efficient.

### 1.2 Speech-Enabling Chess In Emacspeak

To answer some or all of the above questions, I speech-enabled Emacs
Chess last weekend via module emacspeak-chess.el — see User Manual
for complete end-user documentation.

Module `emacspeak-chess` speech-enables Emacs Chess by:

1. Providing interactive commands that let the user navigate and browse the
   chessboard along the eight compass directions from the current square.
2. Spoken output uses audio-formatting — subtle changes in voice
   characteristics backed up by auditory icons — to indicate the
   color of squares and pieces.
3. Speaking each current move as it happens.
4. Adding the same spoken output to `emacs chess` commands for
   moving back and forth through a game.

In the above, all of the heavy lifting is done by three functions:

- emacspeak-chess-describe-square: Speak state of current square.

- emacspeak-chess-collect-squares: Collect squares along a given rank,
  file, or diagonal, starting at and including the current square.
  - emacspeak-chess-describe-move: Describe current move.

Share And Enjoy!

## Meta-Programming In Emacs Using Defadvice

## 1 Introduction

This blog article Meta Programming In Python reminded me to write up
the equivalent for Emacs Lisp.
Decorators in Python enable you to modify the vehavior of existing
functions without changing the original function; Advice in Lisp
which traces back to the 80's enables similar functionality —
incidentally, Advice was the inspiration behind Aspect Oriented
Programming in Java.

## 2 Advice And Emacs Lisp

Advice came to Emacs lisp in the summer of 1994, when module
`advice.el` shipped as part of Emacs 19.23. A few weeks later, a
colleague at work (Win Treese) wrote up a simple example that added
a before advice to the vc-checkin functions of the time to create
an `RCS` subdirectory if one did not exist. This was such a neat
trick that all of us in our Lab adopted it — and having random
RCS*,v* files lying around in the working directory became history.

## 3 Emacspeak And Advice — Fall 1994

And then I decided to make Emacs speak to me.
Module `advice.el` provided the ability to add before, after, or
around advice. In brief, Emacspeak used these three classes of
advice as follows:

1. Speak line moved to after `next-line` and `previous-line` — add
   an after advice that called function `emacspeak-speak-line`.
2. Speak character being deleted — Add a before advice that
   speaks the character under point before it is deleted.
3. Get various types of completion spoken — Add an around advice
   that remembers the current context, calls the original function
   being adviced, and finally speak the current context that now
   reflects the completion.

The rest of the story was written up a few years ago as Emacspeak At
Twenty. Fast-forwarding 25 years, present versions of Emacs still
include module `advice.el` as well as an arguably simplified front-end
implemented by module `nadvice.el` that enables the definition of
custom functions that are then attached to existing code via advice.

San Jose, Calif., (May 4, 2019)

### 1.1 🦮 Emacspeak 50.0 (SageDog) Unleashed!

Advancing Accessibility In The Age Of User-Aware Interfaces — Zero
cost of Ownership makes priceless software Universally affordable!

Emacspeak Inc (NASDOG: ESPK) — http://github.com/tvraman/emacspeak
— announces the immediate world-wide availability of Emacspeak 50.0
(SageDog) — a powerful audio desktop for leveraging today's evolving
Data, Social and Assistant-Oriented Internet cloud.

🚭: Naturally Intelligent (NI)™ at how information is spoken, Emacspeak
is entirely free of Artificial Ingredients (AI)™.

## 2 Investors Note:

With several prominent tweeters expanding coverage of #emacspeak,
NASDOG: ESPK has now been consistently trading over the social net at
levels close to that once attained by DogCom high-fliers—and as of
May 2019 is trading at levels close to that achieved by once
better known stocks in the tech sector.

## 3 What Is It?

Emacspeak is a fully functional audio desktop that provides complete
eyes-free access to all major 32 and 64 bit operating environments. By
seamlessly blending live access to all aspects of the Internet such as
ubiquitous assistance, Web-surfing, blogging, social computing and
electronic messaging into the audio desktop, Emacspeak enables speech
access to local and remote information with a consistent and
well-integrated user interface. A rich suite of task-oriented tools
provides efficient speech-enabled access to the evolving
assistant-oriented social Internet cloud.

## 4 Major Enhancements:

This version requires emacs-26.1 or later.

1. Emacs 26 Support 🤻
2. Updated URL templates 🕷
3. Updated websearch wizards 🧙
4. Updated Bookshare support 📚
5. Updated EWW support 🕸
6. Smart tabs for EWW 📑

11. Speech-enabled navi-mode 🌲

— And a lot more than will fit this margin. … 🗞

## 5 Establishing Liberty, Equality And Freedom:

Never a toy system, Emacspeak is voluntarily bundled with all
major Linux distributions. Though designed to be modular,
distributors have freely chosen to bundle the fully integrated
system without any undue pressure—a documented success for
the integrated innovation embodied by Emacspeak. As the system
evolves, both upgrades and downgrades continue to be available at
the same zero-cost to all users. The integrity of the Emacspeak
codebase is ensured by the reliable and secure Linux platform
used to develop and distribute the software.

Extensive studies have shown that thanks to these features, users
consider Emacspeak to be absolutely priceless. Thanks to this
wide-spread user demand, the present version remains priceless
as ever—it is being made available at the same zero-cost as
previous releases.

At the same time, Emacspeak continues to innovate in the area of
eyes-free Assistance and social interaction and carries forward the
well-established Open Source tradition of introducing user interface
features that eventually show up in luser environments.

On this theme, when once challenged by a proponent of a crash-prone
but well-marketed mousetrap with the assertion "Emacs is a system from
the 70's", the creator of Emacspeak evinced surprise at the unusual
candor manifest in the assertion that it would take popular
idiot-proven interfaces until the year 2070 to catch up to where the
Emacspeak audio desktop is today. Industry experts welcomed this
refreshing breath of Courage Certainty and Clarity (CCC) at a time
when users are reeling from the Fear Uncertainty and Doubt (FUD)
unleashed by complex software systems backed by even more convoluted
press releases.

## 6 Independent Test Results:

Independent test results have proven that unlike some modern (and
not so modern) software, Emacspeak can be safely uninstalled without
adversely affecting the continued performance of the computer. These
same tests also revealed that once uninstalled, the user stopped
functioning altogether. Speaking with Aster Labrador, the creator of
Emacspeak once pointed out that these results re-emphasize the
user-centric design of Emacspeak; “It is the user — and not the
computer– that stops functioning when Emacspeak is uninstalled!”.

### 6.1 Note from Aster,Bubbles and Tilden:

UnDoctored Videos Inc. is looking for volunteers to star in a
video demonstrating such complete user failure.

## 7 Obtaining Emacspeak:

Emacspeak can be downloaded from GitHub — see
https://github.com/tvraman/emacspeak you can visit Emacspeak on the
WWW at http://emacspeak.sf.net. You can subscribe to the emacspeak

## Using Emacs Threads To Execute Commands Asynchronously

## 1 Executive Summary

Emacs 26 has threads for executing functions asynchronously. Emacs
commands that call an external process and wait for that process to
finish make a good candidate for asynchronous execution — e.g.,
`smtpmail-send-it` for sending mail. The arrival of threads provides
an interesting option for running such commands asynchronously.

## 2 First Attempt — Custom Async `gnus` Command

I initially wrote a custom command for launching `gnus` asynchronously
— it was a one-line function that ran the following:

    (make-thread #'gnus)

The above worked well — except when command `gnus` needed user input
— so I just had to be thoughtful about when I called it. But a few
weeks later, I wanted the equivalent for function `smtpmail-send-it`
for sending mail. I almost wrote myself one more command before
stepping back to create a more generic solution.

## 3 One Command To Thread Them All

I have now defined command `emacspeak-wizards-execute-asynchronously`
bound to `C-' a`.
Note that this command, though part of module `emacspeak-wizards`, has
no emacspeak dependencies.

    (defun emacspeak-wizards-execute-asynchronously
          (key)
          "Read
          key-sequence,
          then execute its command on a new thread."
          (interactive
          (list (read-key-sequence "Key Sequence: ")))
          (let ((l
          (local-key-binding key))
          (g (global-key-binding key)))
          (cond
          ( (commandp l)
          (make-thread l)
          (message "Running
          %s
          on a new thread." l))
          ((commandp g)
          (make-thread g)
          (message "Running
          %s
          on a new thread." g))
          (t (error "%s is not bound to a
          command."
          key)))))

          (global-set-key (kbd "C-' a")
          'emacspeak-wizards-execute-asynchronously)

With this command bound to `C-' a`, I can now get rid of my custom
`gnus-async` command and its associated key-binding. I already have
command `gnus` bound to `C-; g`, so I can just press `C-' a C-; g` to
fetch news/mail asynchronously.

Similarly, when sending mail using `smtpmail` I can press `C-' a C-c
C-c` in the `*mail*` buffer to send mail without Emacs blocking.

## 4 Final Caveats

Like other asynchronous solutions (see package `async` for instance)
one needs to make sure that the command being executed asynchronously
will not require user input. In the case of package `async`, the
asynchronous Emacs will block waiting for input; in the case of
`make-thread`, Emacs enters a blocking loop with the minibuffer
continuously displaying

    No catch for ...

The only way to come out is to kill Emacs — so make sure to use
command `emacspeak-wizards-execute-asynchronously` only when you're
sure that the command being run asynchronously will not require user
input.

## Effective Suggest And Complete In An Eyes-Free Environment

## 1 Executive Summary

Emacs has always provided a wealth of techniques for rapid keyboard
input (abbrev, dabbrev, hippie-expandand completion come to mind)
alongside a rich collection of tools for navigating among open
buffers. And these affordances have significantly increased over the
last few years with the arrival of packages like `ido`, `company`,
`helm` etc., each replete with different strategies for rapid task
completion such as flex and fuzzy matching. This article investigates
these tools in an eyes-free environment, specifically in the context
of Emacspeak and rapid task completion. I've not investigated every
possible package in this space — instead, I've picked a collection
of packages and techniques that have worked well in an eyes-free
context. Finally, the ultimate metric I use in each case is the time
to successful task completion — since at the end of the day, that's
the only metric that counts when it comes to user productivity.

## 2 Terminology

For this article, I will use terms suggestion and completion to
mean subtly different concepts. I'll also use terms explore and
filter in describing various phases in user interaction.

Suggestion
  Offer the user some suggestions that help explore the space of choices. (metaphor: avoid the blank sheet of paper syndrome).
Completion
  Filter the available choices based on user input with the goal of reaching the target as rapidly as possible.
Explore
  User does not necessarily know what he is looking for, but expects to be able to recognize what he wants from the displayed choices.
Target
  User knows exactly what he wants, e.g., filename, or function-name, but would still like to get there with the fewest possible number of keystrokes, along with the needed memory aids to guide the decision.

Note that in practice, suggestions and completions work
hand-in-hand, with the visual display playing a central role in
guiding the user through the pace of available choices. In a typical
user interaction session, the space of suggestions gets filtered by
user input to produce the available completions (choices) for the next
round of user input — think of this as a
Suggest/Input/Filter/Target (SIFT) interaction loop. Similarly, explore and
target type activities typically go hand-in-hand, with explore
serving as a memory-aid for locating the target.

## 3 Tasks Where Suggestions And Completions Help Speed Up Task Completion

Here are exemplars of tasks that I perform often and where I require
all the help that Emacs can provide in completing the task as rapidly
as possible:

File Navigation
  Navigating to and opening a file — either code or prose.
Content Navigation
  Jump to a specific location (section, function, class/method, or pattern-match) in that file.
Buffer Navigation
  Jump to an already open buffer in a long-running Emacs.

If that buffer existed — but has since been killed (by
`midnight` for example), then re-open that buffer.
I do everything in Emacs, so open buffers include a large
number of ORG and LaTeX documents, Web Pages opened in EWW
(news sites, documentation, blog articles), IM Chats (I use
`jabber`), Mail Buffers — both open folders and previously
sent messages, and much, much more.

Media
  Easily launch media streams including local and streaming media.
EBooks
  Open (or jump to an already open) EBook to continue reading.
Code Completion
  Complete function/method-name as I type, with an easy affordance to move among the available choices. The Suggest/Input/Filter/Target interaction loop applies here as well.

Notice that as one performs all of these tasks, every target is an
Emacs buffer or Emacs buffer location. In the case of completion, the
target is a string that gets inserted at the current location.

## 4 Features Of Eyes-Free Interaction

Using spoken output — as opposed to a rich visual display — has
the following special features and/or drawbacks:

1. A large visual display can offer the user many choices at a time,
   and the eye's ability to rapidly scan these choices makes for an
   extremely fast Suggest/Input/Filter/Target loop. As an example, an
   interface like `helm` can display a large number of initial
   choices, with the user filtering these down with a few strategic key-presses.
2. Spoken output takes time — and there is simply no way around
   this — speeding up speech-rate helps to a point, but speaking
   50 choices very fast does not help the user in the explore
   phase. This means that effective filtering and ranking of the available
   choices takes on added importance.
3. More importantly, picking a Suggest/Input/Filter/Target (SIFT)
   interaction loop that depends on a large display is sub-optimal
   for eyes-free interaction.
4. Given (2,3), smart filtering, flex/fuzzy matching, and ranking
   based on past user behavior take on added importance in an
   eyes-free environment. As an aside, I have high hopes in this
   area for package `prescient` — though in my few days of usage,
   it has yet to make a difference in my productivity.
5. For many of the tasks enumerated in the previous section, (2, 3
   and 4) make `ido` with flex and fuzzy matching extremely
   effective. In contrast, `helm` with similar flex and fuzzy
   matching (via packages `helm-flx` and `helm-fuzzier`) adds little
   extra benefit — and the fractional extra time to compute and
   display the choices can even lead to a minor productivity hit.
6. When it comes to writing code with completion, package `company`
   has proven extremely effective. Notice that when writing code,
   one rarely if ever resorts to fuzzy matching — this may well
   be subjective. Speaking for myself, I cannot think of function
   or method names in the context of fuzzy matching — said
   differently, it's hard to think `xl` for function-name
   `next-line` — even though in a given filtering context, `xl`
   might define the shortest path through the available choices to
   the target `next-line`. Given this, emacspeak implements a
   `company front-end` that allows the user to navigate through the
   available choices with succinct spoken feedback, and I use those
   choices only after I have typed sufficiently many characters to
   have a manageable number of choices — said differently, though
   package `company` is set up to trigger after 3 characters have
   been typed, I usually end up typing more — and often resort to
   `dabbrev` or `hippee-expand` to input this longer prefix.
7. Some of the shortcomings with eyes-free interaction enumerated
   above lead to my looking for effective work-arounds that might
   well work well outside the eyes-free context, e.g. when the
   available choices are too large to fit on a typical visual
   display. Interestingly, most of these have also been solved by
   mainstream Emacs developers in their never-ending/unerring quest for increased
   productivity — package `ido` and `company` are excellent exemplars.

- Mapping Solutions To Tasks

This section maps the various solutions I use to speed up the tasks
enumerated earlier in this article.

### 4.1 File And Buffer Navigation

I use package `ido` with add-ons `flx-ido` and `ido-completing-read+`
(formerly `ido-ubiquitous`) as my primary/only solution for this
task. I've dabbled with package `helm` — primarily via command
`helm-mini` but have found almost no use-cases where I did better with
`helm`. I also use command `org-switchb` to quickly jump to any of my
open `org` buffers – since that automatically filters the choices
down for me — I can then get to the `org-mode` buffer I want with
one or two keystrokes. Notice that in all of these cases, I'm relying
on the fact that I mostly know what I want, i.e., the explore phase
does not start with an entirely blank sheet of paper.

### 4.2 Content Navigation

Incremental search is your biggest and most effective friend in
effective eyes-free interaction — this simply cannot be stressed
enough. That everything in Emacs is searchable via
incremental-search is a big win for eyes-free interaction. When you
have a large visual display, the human eye is the search interface of
first resort – you typically use a search-command only if the
target is below the fold or far away from the cursor. Because spoken
output takes time, I use isearch even when the target is one or two
lines away.

Structured navigation comes next in my toolbox for navigating content
— `imenu` for code, and section navigation for documents (org,
LaTeX). I also use command `occur` to advantage since that provides a
quick way of finding all the desired targets in a document. Given that
program source-code uses indentation for displaying structure,
hbuilt-in command `selective-display` remains one of Emacs' hidden
treasures with respect to expanding/collapsing source-code.

Finally, I
use a combination of `isearch` and `structured navigation` in
`org-mode` buffres by collapsing the document, and then using
`isearch` to reveal the desired content fragment.
In the case of `LaTeX` documents, I use package `reftex` to
generate a navigation buffer that functions as an interactive table
of contents.

### 4.3 Locating And Playing Media

1. I keep all my music content organized under `~/mp3`.
2. I keep playlist files that contain stream-links to my favorite
   Internet streams under `emacspeak/media`.
3. The afore-mentioned techniques using `ido` enables me to launch
   local and streaming media with a small number of keystrokes. Once
   selected, the content is played via package `emacspeak-m-player`
   which provides Emacs bindings to all `mplayer` functionality
   via that program's `slave-mode`. In addition, Emacspeak also
   implements a smart `emacspeak-m-player-locate-media` which uses
   Emacs' integration with command `locate` to turn the located
   files matching a given pattern into an interactive play-list.

### 4.4 EBooks

Jumping to already open ebooks is no different than buffer
navigation. I organize all my ebooks under a single directory
tree, and module `emacspeak-epub` implements a bookshelf that
allows me to organize and browse my collection along various
axies. Finally, Emacspeak implements a light-weight bookmark
facility that works with `eww` so that I can save my place in an
ebook across Emacs sessions.

### 4.5 Code Completion

As covered earlier, I use `company` along with `dabbrev` and
`hippee-expand` while writing code. I also use `yasnippet` to
generate skeleton code. I use `auto-correct-mode` to
automatically correct repeated errors, and add abbrevs for
commonly occurring typos.

## 5 Summary

1. Emacs' Suggest/Input/Filter/Target (SIFT) interaction loop is just as
   effective in eyes-free interaction — in fact more so .
2. Fuzzy matching when filtering is a big win when working with spoken
   output — it leads to faster task completion.
3. Navigating ones computing environment based on the underlying
   structure and semantics of electronic content is a major win —
   both when working with a visual or spoken display. The advantages
   just become evident far sooner in the eyes-free context due to the
   inherently temporal nature of spoken interaction.

## Emacspeak 48.0 (ServiceDog) Unleashed!

# Emacspeak 48.0—ServiceDog—Unleashed!

*For Immediate Release:

San Jose, Calif., (May 04, 2018)

Emacspeak 48.0 (ServiceDog):
Redefining Accessibility In The Age Of User-Aware Interfaces
–Zero cost of Ownership makes priceless software Universally affordable!

Emacspeak Inc (NASDOG: ESPK) — http://github.com/tvraman/emacspeak
— announces the immediate world-wide availability of Emacspeak 48.0
(ServiceDog) — a powerful audio desktop for leveraging today's
evolving Data, Social and Assistant-Oriented Internet cloud.

## 1 Investors Note:

With several prominent tweeters expanding coverage of #emacspeak,
NASDOG: ESPK has now been consistently trading over the social net at
levels close to that once attained by DogCom high-fliers—and as of
May
2018 is trading at levels close to that achieved by once better known
stocks in the tech sector.

## 2 What Is It?

Emacspeak is a fully functional audio desktop that provides complete
eyes-free access to all major 32 and 64 bit operating environments. By
seamlessly blending live access to all aspects of the Internet such as
ubiquitous assistance, Web-surfing, blogging, social computing and
electronic messaging into the audio desktop, Emacspeak enables speech
access to local and remote information with a consistent and
well-integrated user interface. A rich suite of task-oriented tools
provides efficient speech-enabled access to the evolving
assistant-oriented social Internet cloud.

## 3 Major Enhancements:

This version requires emacs-25.1 or later.

1. Emacs 26 Support 🤻

1. Locate And Play Media ᭳
2. Updated EPub Support 🕮
3. Updated Outloud TTS Server 💬
4. Espeak-NG support📢
5. Smart TTS Prompts 🙊
6. DBus Integration including screenlock via Gnome-ScreenSaver 🚌
7. MPlayer And Equalizer Presets ≝
8. VLC front-end 🎹
9. Updated URL templates 🕷

10. Updated websearch wizards 🕸

    — And a lot more than will fit this margin. … 🗞

## 4 Establishing Liberty, Equality And Freedom:

Never a toy system, Emacspeak is voluntarily bundled with all
major Linux distributions. Though designed to be modular,
distributors have freely chosen to bundle the fully integrated
system without any undue pressure—a documented success for
the integrated innovation embodied by Emacspeak. As the system
evolves, both upgrades and downgrades continue to be available at
the same zero-cost to all users. The integrity of the Emacspeak
codebase is ensured by the reliable and secure Linux platform
used to develop and distribute the software.

Extensive studies have shown that thanks to these features, users
consider Emacspeak to be absolutely priceless. Thanks to this
wide-spread user demand, the present version remains priceless
as ever—it is being made available at the same zero-cost as
previous releases.

At the same time, Emacspeak continues to innovate in the area of
eyes-free Assistance and social interaction and carries forward the
well-established Open Source tradition of introducing user interface
features that eventually show up in luser environments.

On this theme, when once challenged by a proponent of a crash-prone
but well-marketed mousetrap with the assertion "Emacs is a system from
the 70's", the creator of Emacspeak evinced surprise at the unusual
candor manifest in the assertion that it would take popular
idiot-proven interfaces until the year 2070 to catch up to where the
Emacspeak audio desktop is today. Industry experts welcomed this
refreshing breath of Courage Certainty and Clarity (CCC) at a time
when users are reeling from the Fear Uncertainty and Doubt (FUD)
unleashed by complex software systems backed by even more convoluted
press releases.

## 5 Independent Test Results:

Independent test results have proven that unlike some modern (and
not so modern) software, Emacspeak can be safely uninstalled without
adversely affecting the continued performance of the computer. These
same tests also revealed that once uninstalled, the user stopped
functioning altogether. Speaking with Aster Labrador, the creator of
Emacspeak once pointed out that these results re-emphasize the
user-centric design of Emacspeak; “It is the user –and not the
computer– that stops functioning when Emacspeak is uninstalled!”.

### 5.1 Note from Aster,Bubbles and Tilden:

UnDoctored Videos Inc. is looking for volunteers to star in a
video demonstrating such complete user failure.

## 6 Obtaining Emacspeak:

Emacspeak can be downloaded from GitHub –see
https://github.com/tvraman/emacspeak you can visit Emacspeak on the
WWW at http://emacspeak.sf.net. You can subscribe to the emacspeak

## Updating Voxin TTS Server To Avoid A Possible ALSA Bug

## 1 Summary

I recently updated to a new Linux laptop running the latest Debian
(Rodete). The upgrade went smoothly, but when I started using the
machine, I found that the Emacspeak TTS server for Voxin (Outloud)
crashed consistently; here, consistently equated to crashing on short
utterances which made typing or navigating by character an extremely
frustrating experience.

I fixed the issue by creating a work-around in the TTS server
atcleci.cpp::xrun
— if you run into this issue, make sure to update and rebuild
atcleci.so from GitHub; alternatively, you'll find an updated
`atcleci.so` in the `servers/linux-outloud/lib/` directory after a
git update that you can copy over to your `servers/linux-outloud`
directory.

## 2 What Was Crashing

I use a DMIX plugin as the default device — and have many ALSA
virtual devices that are defined in terms of this device — see my
asoundrc. With this configuration, writing to the ALSA device was
raising an EPIPE error — normally this error indicates a buffer
underrun — that's when ALSA is starved of audio data. But in many
of these cases, the ALSA device was still in a RUNNING rather than
an XRUN state — this caused the Emacspeak server to
abort. Curiously, this happened only sporadically — and from my
experimentation only happened when there were multiple streams of
audio active on the machine.
A few Google searches showed threads on the alsa/kernel devel lists
that indicated that this bug was present in the case of DMIX devices
— it was hard to tell if the patch that was submitted on the
alsa-devel list had made it into my installation of Debian.

## 3 Fixing The Problem

My original implementation of function xrun had been cloned from
aplay.c about 15+ years ago — looking at the newest aplay
implementation, little to nothing had changed there. I finally worked
around the issue by adding a call to

    snd_pcm_prepare(AHandle)

whenever ALSA raised an EPIPE error during write — with the ALSA
device state in a RUNNING rather than an XRUN state. This
appears to fix the issue.

## 4 Establishing Liberty, Equality And Freedom:

Never a toy system, Emacspeak is voluntarily bundled with all
major Linux distributions. Though designed to be modular,
distributors have freely chosen to bundle the fully integrated
system without any undue pressure—a documented success for
the integrated innovation embodied by Emacspeak. As the system
evolves, both upgrades and downgrades continue to be available at
the same zero-cost to all users. The integrity of the Emacspeak
codebase is ensured by the reliable and secure Linux platform
used to develop and distribute the software.

Extensive studies have shown that thanks to these features, users
consider Emacspeak to be absolutely priceless. Thanks to this
wide-spread user demand, the present version remains priceless
as ever—it is being made available at the same zero-cost as
previous releases.

At the same time, Emacspeak continues to innovate in the area of
eyes-free Assistance and social interaction and carries forward the
well-established Open Source tradition of introducing user interface
features that eventually show up in luser environments.

On this theme, when once challenged by a proponent of a crash-prone
but well-marketed mousetrap with the assertion "Emacs is a system from
the 70's", the creator of Emacspeak evinced surprise at the unusual
candor manifest in the assertion that it would take popular
idiot-proven interfaces until the year 2070 to catch up to where the
Emacspeak audio desktop is today. Industry experts welcomed this
refreshing breath of Courage Certainty and Clarity (CCC) at a time
when users are reeling from the Fear Uncertainty and Doubt (FUD)
unleashed by complex software systems backed by even more convoluted
press releases.

## 5 Independent Test Results:

Independent test results have proven that unlike some modern (and
not so modern) software, Emacspeak can be safely uninstalled without
adversely affecting the continued performance of the computer. These
same tests also revealed that once uninstalled, the user stopped
functioning altogether. Speaking with Aster Labrador, the creator of
Emacspeak once pointed out that these results re-emphasize the
user-centric design of Emacspeak; "It is the user –and not the
computer– that stops functioning when Emacspeak is uninstalled!".

### 5.1 Note from Aster,Bubbles and Tilden:

UnDoctored Videos Inc. is looking for volunteers to star in a
video demonstrating such complete user failure.

## 6 Obtaining Emacspeak:

Emacspeak can be downloaded from GitHub –see
https://github.com/tvraman/emacspeak you can visit Emacspeak on the
WWW at http://emacspeak.sf.net. You can subscribe to the emacspeak
mailing list — emacspeak@cs.vassar.edu — by sending mail to the

## Emacs Start-Up: Speeding It Up

## 1 TL;DR:

Describes my Emacs start-up file, and what I did to speed it up from
12 seconds to under 4 seconds.

## 2 Overview Of Steps

- Byte-compile start-up files.
- Temporarily increase gc-cons-threshold during startup.
- Load package autoloads (not packages) during start-up.
- Use eval-after-load to advantage for post-package setup.
- Lexically bind file-name-handler-alist to nil if start-up
  is split across many files.
- Used memoization to avoid network lookup of current location during startup.

I have a large number of elpa/melpa packages installed:

    (length load-path)

    400

With the above, my emacs (Emacs 26 built from Git) startup time is on
average 4 seconds. This includes starting up emacspeak (including
speech servers), as well as launching a number of project-specific
shell buffers. Given that I rarely restart Emacs, the startup time is
academic — but speeding up Emacs startup did get me to clean-up my
Emacs setup.

## 3 Introduction

I have now used Emacs for more than 25 years, and my Emacs start-up
file has followed the same structure through this time.

1. The init file defines a `start-up-emacs` function that does the
   bulk of the work.
2. Package-specific configuration is split up into
   `<package>-prepare.el` files.
3. All of these files are byte-compiled.

As a first step, I added code to my start-up file to time the loading
of various modules.

## 4 Load Byte-Compiled Start-Up File

I keep my `emacs-startup.el` checked into GitHub.
My Emacs init-file is a symlink to the byte-compiled version of the
above — this is something that goes back to my time as a
grad-student at Cornell (when GitHub of course did not exist).
That is also when I originally learnt the trick of temporarily setting
gc-cons-threshold to 8MB — Emacs' default is 800K.

## 5 Package Autoloads And `eval-after-load`

Over time, some of the package-specific setup files had come to
directly load packages — it just made it easier to do
package-specific setup at the time. As part of the cleanup, I updated
these to strictly load package-autoload files and wrapped post-package
setup code in `eval-after-load` — this is effectively the same as
using `use-package`.

## 6 Loading Files Faster

Emacs has an extremely flexible mechanism for loading files — this
means you can load compressed, encrypted or remote files without
having to worry about it. That flexibility comes at a cost — if you
are sure you dont need this flexibility during start-up, then locally
binding `file-name-handler-alist` to `nil` is a big win — in my
case, it sped things up by 50%.

## 7 Avoid Network Calls During Start-Up

In my case, I set `calendar-latitude` and `calendar-longitude` by
geocoding my address — geocoding is done by calling the Google Maps
API. The geocoding API is plenty fast that you normally dont notice
it — but it was adding anywhere from 1–3 seconds during
startup. Since my address doesn't change that often, I updated module
gmaps to use a memoized version. My address is set via `Customize`,
and the geocoded lat/long is saved to disk automatically.

   tip of them all.

## Data-Binding In Emacs Lisp: let-alist When Processing JSON Data

## 1 Summary

Module json-read consumes JSON data structures and transforms them
into their elisp equivalent, where JSON dictionaries become alists and
JSON arrays become vectors. Accessing that data from lisp would
ordinarily require using lisp accessors such as assoc, car and
cdr. With let-alist, we get data-binding for free — the result
is elisp code that uses dotted-variables to directly access specific
slots in a deeply nested data structure. Thus, processing data
available as JSON via Web APIs is a really good use-case for
let-alist. Long-standing wish — I wish Emacs' JSON parsing were
implemented in native code rather than in elisp.

### 1.1 A Working Example

I recently implemented myself a NOAA Weather API Client — it pulls
the NOAA Weather Forecast (weekly and hourly) as JSON objects, and
produces an org-mode buffer that renders the data.
Note that though the above is part of a much larger
emacspeak-wizards module, the above function and its dependencies
are themselves mostly independent of Emacspeak, except for the last
two forms in the weather forecast function.
Here is an annotated version of the function that gets NOAA data and
leverages let-alist to process the results:

    (defun ems--noaa-get-data (ask)
          "Internal function that gets NOAA data and returns a results
          buffer."
          (declare (special gweb-my-address))
          (let* ((buffer (get-buffer-create "*NOAA Weather*"))
          (inhibit-read-only  t)
          (date nil)
          (start (point-min))
          (address (when ask (read-from-minibuffer "Address:")))
          (geo  (when ask (gmaps-geocode address))))
          (unless address (setq address gweb-my-address))
          (with-current-buffer buffer
          (erase-buffer)
          (special-mode)
          (orgstruct-mode)
          (setq header-line-format (format "NOAA Weather For %s"
          address))      (insert (format "* Weather Forecast For
          %s\n\n"
          address))
          ;;; produce Daily forecast
          (let-alist (g-json-from-url (ems--noaa-url geo))
          (cl-loop
          for p across .properties.periods do
          (let-alist p
          (insert
          (format
          "** Forecast For %s: %s\n\n%s\n\n"
          .name .shortForecast .detailedForecast)))
          (fill-region start (point)))
          (insert
          (format "\nUpdated at %s\n"
          (ems--noaa-time "%c" .properties.updated))))
          (let-alist ;;; Now produce hourly forecast
          (g-json-from-url (concat (ems--noaa-url geo) "/hourly"))
          (insert
          (format "\n* Hourly Forecast:Updated At %s \n"
          (ems--noaa-time "%c" .properties.updated)))
          (cl-loop
          for p across .properties.periods do
          (let-alist p
          (unless (and date (string= date (ems--noaa-time "%x"
          .startTime)))
          (insert (format "** %s\n" (ems--noaa-time "%A
          %X"      .startTime)))
          (setq date (ems--noaa-time "%x" .startTime)))
          (insert
          (format
          "  - %s %s %s:  Wind Speed: %s Wind Direction: %s\n"
          (ems--noaa-time "%R" .startTime)
          .shortForecast
          .temperature .windSpeed .windDirection)))))
          (goto-char (point-min)))
          buffer))

1. In the above_ /gweb-my-address_ is a Lat/Lng pair as returned by
   gmaps-geocode defined in g-client/gmaps.el. That is used as the
   default location for which we retrieve the forecast.
2. Parameter ask if non-nil results in the user being prompted
   for the address — that address is then geocoded using
   the Google Maps API.
3. The weather forecast display will leverage org-mode for
   structured navigation; however we dont want that buffer to be
   editable in general; moreover special-mode gives us nice
   features such as q for quitting that window. So we use
   special-mode as the major mode, and orgstruct-mode as a minor
   mode to get the best of both worlds.
4. The API call to NOAA results in a JSON data structure where
   result.properties.periods holds an array of forecast
   objects. Using that result in let-alist gives us data binding
   for free! Notice the following:
   1. We can use .properties.periods in the cl-loop as the list
      to iterate over.
   2. Within that loop body, a second let-list enables data
      binding over the forecast object that we are processing in the
      loop body.
   3. Data accesses inside the loop body are again simple given the
      data binding created by the let-alist.

The code for generating the hourly forecast is similar in spirit —
the main take-away here is that let-alist saves a lot of
boiler-plate code that would have been otherwise required to take
apart the nested list structure we got back with our data.

## Spatial Audio: ALSA Virtual Devices Using LADSPA

## 1 Overview

I have long wanted to apply HRTF filters to soundscapes on the
Emacspeak Audio Desktop to produce effects that are better
spatialized. I just got this working over the weekend using LADSPA
Plugin ZamHeadX2-ladspa.so from package zam-plugins.

## 2 Getting ZAM Plugins

    git
          clone
          https://github.com/zamaudio/zam-plugins.git

And follow the instructions in the README file.

Next, do

    sudo make install

to install the plugins.

Finally, make sure that the install location is on your LADSPA path.

### 2.1 Adding HRTF Virtual Devices Via ASOUNDRC

After updating Emacspeak from GitHub,
open file servers/linux-outloud/asoundrc
and copy the section marked HRTF to your personal .asoundrc —
this defines a number of virtual devices that use the newly installed
LADSPA plugin.
Beware: Back-up your .asoundrc first and make sure you can restore
it even if you lose speech.

## 3 Spatialized Soundscapes

In a running Emacspeak session, invoke command

    soundscape-restart

with an interactive prefix arg and specify one of the available
devices using standard Emacs completion.

For use with Soundscapes, I recommend one of the devices that place
sound directly in front of the listener (azimuth 0) but with a non-0
elevation.

The HRTF devices are named with prefix tts because I would like to
use these with software TTS; but for now the result with TTS is not
as good as it is with Soundscapes.

Notice that command soundscape-restart offers a number of virtual
ALSA devices based on your .asoundrc; see the next section for a
summary.

## 4 Virtual ALSA Devices For Use As A Soundscape Filter

Here is a list of available LADSPA devices in my setup that can be
used to add additional effects to Soundscapes:

- crossfeed: Apply a BS2B filter.
- default: No filters, vanilla audio.
- tap-reverb: Reverb filter from package tap-plugins.
- reverb-crossfeed: Reverb filter followed by BS2B.
- tts-a0-e15: HRTF at (0, 15).
- tts-a0-e30: HRTF at (0, 30).
- tts-a0-e60: HRTF at (0, 60).
- tts-a0-e90: HRTF at (0, 90).
- tts-a0-em15: HRTF at (0, -15).
- tts-a0-em30: HRTF at (0, -30).
- tts-a0-em45: HRTF at (0, -45).
- tts-a135-e45: HRTF at (135, 45).
- tts-a135-em45: HRTF at (135, -45).
- tts-a225-e45: HRTF at (225, 45).
- tts-a225-em45: HRTF at (225, -45).
- tts-a45-e45: HRTF at (45, 45).
- tts-a45-em45: HRTF at (45, -45).
- tts-am45-e45: HRTF at (-45, 45).
- tts-am45-em45: HRTF at (-45, -45).

## 5 Other Uses Of HRTF Devices

You can experiment with these devices using aplay e.g.:

    aplay -Dtts_a0_e0
          filename.wav

You can also apply the HRTF Ladspa plugin from within MPlayer when
using emacspeak.
To try this, use C-e ; f and pick the Zam effect when prompted.
Invoke that command with an interactive prefix arg — C-u C-e ; f
— to edit the params passed to the Zam filter.

HRTF filters when playing media are mostly useful to position a
radio station in 3d space when playing more than one station
simultaneously.

Emacspeak audio desktop is today. Industry experts welcomed this
refreshing breath of Courage Certainty and Clarity (CCC) at a time
when users are reeling from the Fear Uncertainty and Doubt (FUD)
unleashed by complex software systems backed by even more convoluted
press releases.

## 5 Independent Test Results:

Independent test results have proven that unlike some modern (and
not so modern) software, Emacspeak can be safely uninstalled without
adversely affecting the continued performance of the computer. These
same tests also revealed that once uninstalled, the user stopped
functioning altogether. Speaking with Aster Labrador, the creator of
Emacspeak once pointed out that these results re-emphasize the
user-centric design of Emacspeak; "It is the user –and not the
computer– that stops functioning when Emacspeak is uninstalled!".

### 5.1 Note from Aster,Bubbles and Tilden:

UnDoctored Videos Inc. is looking for volunteers to star in a
video demonstrating such complete user failure.

## Mail On The emacspeak Audio Desktop

# Email On The Emacspeak Audio Desktop

## 1 Overview

This question comes up every few months on the emacspeak mailing
list. In general, see
Emacspeak Tools to quickly discover available speech-enabled
applications. This article outlines some of the available email setups
given the wide degree of variance in this space.

## 2 Background

How one puts together an email environment is a function of the
following:

1. How email is retrieved.
2. How email is stored (if storing locally).
3. How email is sent.

Here is an overview of what is available as viewed from the world of
Linux in general and Emacs in particular:

### 2.1 Email Retrieval

Email can be retrieved in a number of ways:

- IMap via Emacs This is implemented well in GNUS, and poorly in
  Emacs/VM. Note that Emacs is single-threaded, and fetching large
  volumes of email via IMap is painful.
- Batch Retrieval: IMap Tools like fetchmail, offlineimap and friends that live
  outside of Emacs can be used to batch-retrieve email in the
  background. The retrieved mail gets delivered locally as in the past.
- Mail Filtering: UNIX procmail enables filtering of locally
  delivered email into separate folders for automatically organizing
  incoming email.

### 2.2 Sending Email

Sending email involves:

1. Composing email — typically invoked via key-sequence C-x m
   (command: compose-mail). Emacs email packages implement
   specific versions of this command, e.g. vm-mail from package
   emacs/vm, message-mail from the message package etc.
2. Sending email: This is specific to the email provider being used,
   e.g., GMail. In the past, UNIX machines could talk SMTP to
   the Mail Gateway, but this has mostly disappeared over time. For
   an example of how to configure Emacs to send email via GMail
   using SMTP , see file tvr/gm-smtp.el in the emacspeak repository.

### 2.3 Local Storage Format

- UNIX Mail: An email folder is a file of messages. This
  format is used by clients like Emacs/VM, UNIX Mail etc.
- Maildir: A mail folder is a directory, with
  individual email messages living in files of their
  own. Sample clients include MH-E (UNIX MH), MU4E.
- RMail This is Emacs' original email format.

## 3 Putting It All Together

The next sections show my present email setup put together using the
building blocks described above.

1. I use Linux on all my machines, and Android on my phone.
2. I mostly limit email usage on my phone to get a quick overview of email that might require immediate attention — toward this end, I have a to-mobile GMail label that collects urgent messages.
3. Linux is where I handle email in volume.
4. I use my Inbox as

my ToDo list — which means that I leave little or no email in my
Inbox unless I'm on vacation and disconnected from email.

### 3.1 Desktop: Batch Retrieval And Emacs/VM

This is the email setup on my workstation. See next section for the
email setup while mobile.

1. I batch-retrieve email using fetchmail.
2. This email gets filtered through procmail and auto-filed into
   several folders based on a set of procmail rules. Typical rules
   include separating out various email lists into their respective folders.
3. Note that this does not preclude using IMap via GNUS to read
   email while online.
4. Email that is not filtered into separate folders e.g. email that
   is sent directly to me, email regarding projects that need
   immediate attention etc., land up in folder ~/mbox.
5. So when I launch emacs/vm on my desktop, the above is all I
   need to deal with at any given moment.
6. I typically read Auto-filed mailing lists using emacs/vm about once a day or
   less — I use package mspools to get a quick overview of the
   state of those mail folders.

### 3.2 Mobile AccessOn Laptop: GNUS And IMap

See gnus-prepare.el for my gnus configuration for accessing GMail
via imap. That configuration is setup to access multiple GMail accounts.

1. I see each GMail label as a separate group in GNUS.
2. I only sync high-priority labels — this works well even
   over slow WIFI connections while on the road. As an example, the
   afore-mentioned to-mobile GMail label is a high-priority group.
3. Module gm-nnir defines a GNUS/GMail extension that enables
   one to search GMail using GMail's search operators — that is my
   prefered means of quickly finding email messages using
   search. This is very fast since the search happens server-side,
   and only email headers are retrieved when displaying the search
   hits.
4. Note that this solution is not laptop/mobile specific — I use
   this setup for searching GMail from my desktop as well.

### 3.3 Composing And Sending EMail

1. I use compose-mail to compose email.
2. I optionally activate orgtbl-mode and/or orgstruct-mode if
   editing structured content within the email body.
3. I send email out using the setup in gm-smtp.el.

## 4 Conclusion

1. Email in Linux/Emacs is composed of a set of
   independent building blocks — this gives maximal flexibility.
2. That flexibility allows one to put together different email
   workflows depending on the connectivity environment in use.

## Emacs: Check Interactive Call For Emacspeak

## 1 Background

Emacspeak uses advice as the means to speech-enable Emacs.
Emacspeak's advice forms need to check if the function being
speech-enabled is being called interactively — otherwise one would
get a lot of chatter as these functions get called from within elisp
programs, e.g. functions like forward-sexp or kill-sexp, that play
the dual role of both an interactive command, as well as a convenient
elisp function.

Until Emacs 24, the solution used was to write code that did the
following check:

    (when (interactive-p) ...

In Emacs-24, interactive-p was made obsolete and replaced with

    (called-interactively-p
          'interactive)

Emacspeak initially used the above form to perform the equivalent
check. However, around the same time, Emacs' advice implementation
went through some changes, and there was an attempt to replace
advice.el with nadvice.el.

At the end of that round of changes, some problems emerged with the
new called-interactively-p implementation; specifically, calling
:called-interactively-p_ within around advice forms resulted in hard
to debug errors, including one case of infinite recursion involving
library smie.el when invoked from within ruby-mode.

After studying the problem in depth in 2014, I decided to create an
Emacspeak-specific implementation of the is-interactive check.

The resulting implementation has worked well for the last 30 months;
this article is here mostly to document how it works, and the reason
for its existence. Note that Emacspeak uses this custom predicate
only within advice forms. Further, this predicate has been coded
to only work within advice forms created by emacspeak. This
constraint can likely be relaxed, but the tighter implementation is
less risky.

## 2 Implementation — ems-interactive-p

### 2.1 Overview

Within an advice forms defined by Emacspeak, detect if the enclosing
function call is the result of explicit user interaction, i.e. by
pressing a key, or via an explicit call to
call-interactively. Emacspeak produces auditory feedback only if
this predicate returns t.

We first introduce a flag that will be used to record if the enclosing
(containing) function has an Emacspeak-defined advice on it and is
called interactively — these are the only cases that our predicate
needs to test.

    (defvar
          ems-called-interactively-p nil
          "Flag that records if containing function was called
          interactively."

Next, we define a function that checks if interactive calls to a
function should be recorded. We're only interested in functions that
have an advice form defined by Emacspeak — all Emacspeak-defined
advice forms have the name emacspeak.

    (defun ems-record-interactive-p
          (f)
          "Predicate to test if we need to record interactive calls of
          this function. Memoizes result for future use by placing a
          property 'emacspeak on the function symbol."
          (cond
          ((not (symbolp f)) nil)
          ((get f 'emacspeak) t) ; already memoized
          ((ad-find-some-advice f 'any  "emacspeak") ; there is
          an
          emacspeak advice
          (put f 'emacspeak t)) ; memoize for future and return true
          (t nil)))

This is a memoized function that remembers earlier invocations by
setting property emacspeak on the function symbol.

All advice forms created by Emacspeak are named emacspeak, so we
can test for the presence of such advice forms using the test:

    (ad-find-some-advice f 'any
                "emacspeak")

If this test returns T, we memoize the result and return it.

Next, we advice function call-interactively to check
if the function being called interactively is one of the functions
that has been adviced by Emacspeak. If so, we record the fact in the
previously declared global flag
ems-called-interactively-p.

    (defadvice call-interactively
          (around emacspeak  pre act comp)
          "Set emacspeak  interactive flag if there is an Emacspeak
          advice
          on the function being called."
          (let ((ems-called-interactively-p ems-called-interactively-p)) ;
          preserve
          enclosing state
          (when (ems-record-interactive-p (ad-get-arg 0))
          (setq ems-called-interactively-p (ad-get-arg 0)))
          ad-do-it))

We define an equivalent advice form on function
funcall-interactively as well. Now, whenever any function that has
been adviced by Emacspeak is called interactively, that interactive
call gets recorded in the global flag. In the custom Emacspeak
predicate we define, we check the value of this flag, and if
set, consume it, i.e. unset the flag and return T.

    (defsubst ems-interactive-p ()
          "Check our interactive flag.
          Return T if set and we are called from the advice for the current
          interactive command. Turn off the flag once used."
          (when ems-called-interactively-p                 ; interactive call
          (let ((caller (cl-second (backtrace-frame 1))) ; name of containing
          function
          (caller-advice  ;advice generated wrapper
          (ad-get-advice-info-field ems-called-interactively-p
          'advicefunname))          (result nil))
          (setq result
          (or (eq caller caller-advice) ; called from our advice
          (eq ems-called-interactively-p caller))) ; called from advice
          wrapper      (when result
          (setq ems-called-interactively-p nil) ; turn off now that we used
          it      result))))

The only fragile part of the above predicate is the call to
backtrace-frame which we use to discover the name of the enclosing
function. Notice however that this is no more fragile than the current
implementation of called-interactively-p — which also uses
backtrace-frame; If there are changes in the byte-compiler, this
form may need to be updated. The implementation above has the
advantage of working correctly for Emacspeak's specific use-case.

## Audio Deja Vu: Audio Formatted Math On The Emacspeak Desktop

## 1 Overview

This article previews a new feature in the next Emacspeak release —
audio-formatted Mathematics using Aural CSS. Volker Sorge worked
at Google as a Visiting Scientist from Sep 2012 to August 2013, when
we implemented math
access in ChromeVox — see this brief overview. Since leaving
Google, Volker has refactored and extended his work to create an Open
Source Speech-Rule-Engine implemented using NodeJS. This
speech-rule-engine can be used in many different environments;
Emacspeak leverages that work to enable audio-formatting and
interactive browsing of math content.

## 2 Overview Of Functionality

Math access on the Emacspeak desktop is implemented via module
emacspeak-maths.el — see js/node/Readme.org in the Emacspeak GitHub
repository for setup instructions.

Once loaded, module `emacspeak-maths` provides a Math Navigator that
implements the user interface for sending Math expressions to the
Speech-Rule-Engine, and for interactively browsing the resulting
structure. At each step of the interaction, Emacspeak receives math
expressions that have been annotated with Aural CSS and produces
audio-formatted output. The audio-formatted text can itself be
navigated in a special Spoken Math emacs buffer.

Module `emacspeak-maths.el` implements various affordances for
dispatching mathematical content to the Speech-Rule-Engine — see
usage examples in the next section.

## 3 Usage Examples

### 3.1 The Emacspeak Maths Navigator

- The maths navigator can be invoked by pressing S-SPC (hold
  down Windows key and press SPC) — this runs the command emacspeak-maths-navigator/body.
- Once invoked, the /Maths Navigator can be used to enter an
  expression to read.
- Pressing SPC again prompts for the LaTeX math expression.
- Pressing RET guesses the expression to read from the current context.
- The arrow keys navigate the expression being read.
- Pressing o switches to the Spoken Math buffer and exits the
  navigator.

See the relevant chapter in the online Emacspeak manual for details.

### 3.2 Math Content In LaTeX Documents

1. Open a LaTeX document containing math content.
2. Move point to a line containing mathematical markup.
3. Press S-SPC RET to have that expression audio-formatted.
4. Use arrow keys to navigate the resulting structure.
5. Press any other key to exit the navigator.

### 3.3 Math Content On Wikipedia

1. Open a Wikipedia page in the Emacs Web Wowser (EWW) that has
   mathematical content.
2. Wikipedia displays math as images, with the alt-text giving the
   LaTeX representation.
3. Navigate to some math content on the page, then press S-SPC
   a to speak that content — a is for alt.
4. As an example, navigate to Wikipedia Math Example, locate math expressions on that page, then
   press S-SPC a.

### 3.4 Math Content From The Emacs Calculator

1. The built-in Emacs Calculator (`calc`) provides many complex
   math functions including symbolic algebra.
2. For my personal `calc` setup, see tvr/calc-prepare.el in the
   Emacspeak GitHub repo.
3. This setting below sets up the Emacs Calculator to output results
   as LaTeX: (setq calc-language 'tex)
4. With the above setting in effect, launch the emacs Calculator by
   pressing M-##.
5. Press ' — to use algebraic mode — and enter `sin(x)`.
6. Press a t to get the Taylor series expansion of the above
   expression, and press x when prompted for the variable.
7. This displays the Taylor Series expansion up to the desired
   number of terms — try 7 terms.
8. Now, with Calc having shown the results as TeX, press S-SPC
   RET to browse this expression using the Maths Navigator.

## 4 And The Best Is Yet To Come

This is intentionally called an early preview because there is still
much that can be improved:

1. Enhance the rule engine to infer and convey more semantics.
2. Improved audio formatting rules to better present the available information.
3. Update/tune the use of Aural CSS properties to best leverage
   today's TTS engines.
4. Integrate math-reading functionality into more usage contexts in
   addition to the ones enumerated in this article.

## Fun With TTS (Voxin) And Ladspa

## 1 Executive Summary

Voxin 1.6 — AKA ViaVoice Outloud — no longer requires that the
Emacspeak TTS server be built as a 32-bit binary. This means that
installing Voxin on 64-bit systems is now significantly easier since
you no longer need to install 32-bit versions of TCL, TCLX, and the
dependencies needed by library libibmeci.so. In addition to
easing the installation process, not needing 32-bit binaries means
that the Emacspeak Outloud server can now take advantage of audio
processing such as that provided by LADSPA.

## 2 Going 64-Bit: Upgrading To Voxin 1.6

1. Install Voxin-1.6 or later from Voxin.
2. Update Emacspeak from GitHub (this will be part of the next
   public release).
3. Rebuild the atcleci.so binary in the servers/linux-outloud
   directory:

    cd
          servers/linux-outloud
          && make clean && make

If all goes well, you'll now have a 64-bit version of atcleci.so.
You can now run the Outloud server as servers/outloud.
In about a year's time, servers/32-outloud will move to
servers/obsolete, as will the associated servers/32-speech-server
and servers/ssh-32-outloud.

## 3 Applying LADSPA Effects Processing To TTS

With a 64-bit build of atcleci.so in place, we can now call on
installed LADSPA plugins to apply digital sound processing to TTS
output. To experiment with the possibilities, see some of the
virtual sound devices defined in servers/linux-outloud/asoundrc.
Copy over that file to your ~/.asoundrc after updating it to match
your sound setup — you'll likely need to change the default
sound-card to match your setup.
You can now set environment variable `ALSA_DEFAULT` to one of the
`tts_<effect>` virtual devices — and have the Outloud server apply
the specified LADSPA effect to the generated TTS. Here is an example:

    cd servers
          (export ALSA_DEFAULT=tts_reverb; ./outloud)
          tts_selftest

## 4 The Best Is Yet To Come …

The possibilities are endless — ALSA with LADSPA provides a rich
suite of audio processing possibilities.

## 5 Acknowledgements

I'd like to acknowledge Gilles Casse for his work over the years on
ensuring that Linux users have access to good quality TTS. Outloud
would have been dead a long time ago if it weren't for his continued
efforts toward keeping the lights on. His newest creation, libvoxin
that forms the crux of Voxin-1.6 is an excellent piece of engineering
that is likely to help Outloud survive for the future on modern Linux
distros. Note that Gilles is also the primary author of the Emacspeak
ESpeak server.

## Follow-Up: Soundscapes On The Emacspeak Audio Desktop

## 1 Executive Summary

Nearly a year ago, I blogged here about Soundscapes on the emacspeak
Audio Desktop. That article ended with this following paragraph:

    I implemented package
          soundscape to
          create a platform that would let me experiment
          with different tools that aid in concentration. After using
          Soundscapes
          for about a week,
          I have also found that it reduces some of the fatigue that results
          from
          having to listen
          to synthetic text-to-speech for extended periods. The true value (if
          any)
          of this package
          will be a function of how heavily I find myself using it six months
          from
          now --- as a
          metric, complete success might mean that in mid-2016, I still have
          automatic soundscapes
          turned on.

## 2 And Nearly A Year Later …

I have not found the need to turn off Soundscapes in Emacspeak. As
conjectured, it has definitely increased my productivity, specifically
in terms of staying focused on a given task at hand. Over the year,
I've also augmented the emacspeak Audio Desktop with support for
binaural audio — see module `sox-gen` — which provides a collection of
binaural themes for use during different times of the day. Binaural
themes generated by that module overlay Emacspeak Soundscapes to
provide an ideal auditory environment for use over headphones.

## 3 Soundscape Enhancements

Since the publication of the original article, Emacspeak Soundscapes
have been enhanced with additional sounds from
Freesound.org. Emacspeak Soundscapes have been updated to take
advantage of Boodler's limited abilities in the areas of spatial
positioning. I typically use `Soundscapes` with one of several virtual
ALSA devices that have been configured to apply different Ladspa
effects such as reverb or crossfeed depending on the ambient
environment where I am working — this significantly improves the
spatialization of soundscapes being played — see file
ladspa-asoundrc. Finally, the mapping of Soundscapes to various Emacs
modes has also been tuned. — see table below.

Soundscape (Mood) | List Of Major Modes
BirdSongs | shell term
BlopEchoes | elfeed-search
Bonfire | calendar diary
BuddhaLoop | comint
Cavern | prog
ChangingLoops | special
ChangingLoopsPitches | lisp-interaction
Drip | message gnus-summary gnus-article gnus-group mspools vm-presentation vm mail twittering jabber-roster jabber-chat erc
LoopStew | emacspeak-m-player
NoStormYet | fundamental
RainForever | Info help Man Custom messages-buffer
RainSounds | magit vc
Still | text view
SurfWaves | w3 eww
TonkSpace | tabulated-list
WaterFlow | dired

## 4 Summary

As outlined in a previous article, sound on Linux provides unending
possibilities with respect to innovation, here's looking forward to
better things to come.

## Emacspeak 45.0 (IdealDog) Unleashed!

# Emacspeak 45.0—IdealDog—Unleashed!

For Immediate Release:

San Jose, Calif., (Nov 21, 2016)

Emacspeak: Redefining Accessibility In The Era Of (Real)Intelligent Computing
–Zero cost of Ownership makes priceless software Universally affordable!

Emacspeak Inc (NASDOG: ESPK) — http://github.com/tvraman/emacspeak — announces the
immediate world-wide availability of Emacspeak 45.0 (IdealDog) — a
powerful audio desktop for leveraging today's evolving data, social
and service-oriented Internet cloud.

## 1 Investors Note:

With several prominent tweeters expanding coverage of
#emacspeak, NASDOG: ESPK has now been consistently trading over
the social net at levels close to that once attained by DogCom
high-fliers—and as of Nov 2016 is trading at levels close to
that achieved by once better known stocks in the tech sector.

## 2 What Is It?

Emacspeak is a fully functional audio desktop that provides complete
eyes-free access to all major 32 and 64 bit operating environments. By
seamlessly blending live access to all aspects of the Internet such as
Web-surfing, blogging, social computing and electronic messaging into
the audio desktop, Emacspeak enables speech access to local and remote
information with a consistent and well-integrated user interface. A
rich suite of task-oriented tools provides efficient speech-enabled
access to the evolving service-oriented social Internet cloud.

## 3 Major Enhancements:

- Speech-enabled `tide` for typescript development. 🌊
- Speech-enabled `jade` for Javascript WebApp development. ⺩
- Improved `slime` support for Lisp programming. Λ
- Support for rst-mode for editting ReST files.🖹
- Version control info in modeline.⎔
- Speech-enabled `elisp-refs` to aid in refactoring. ※
- GPG integration including pinentry support. 🔐
- ElScreen support for window-layout management. 🆜
- Updated Librivox client for audio books. 🔊🕮
- Updated sound themes. 🔉
- Support for Emacs' visual-line-mode. 🎁
- Speech-enabled Threes game. 🎮
- Updated Google News support. 📰
- Binaural audio support including several predefined binaural themes. ℗
  - Updated multilingual support for ESpeak. 󠀁
- Script etc/bootstrap.sh for bootstrapping into Emacspeak on a well-configured Linux system. 👢
- And a lot more than wil fit this margin. … 🗞

## 4 Establishing Liberty, Equality And Freedom:

Never a toy system, Emacspeak is voluntarily bundled with all
major Linux distributions. Though designed to be modular,
distributors have freely chosen to bundle the fully integrated
system without any undue pressure—a documented success for
the integrated innovation embodied by Emacspeak. As the system
evolves, both upgrades and downgrades continue to be available at
the same zero-cost to all users. The integrity of the Emacspeak
codebase is ensured by the reliable and secure Linux platform
used to develop and distribute the software.

Extensive studies have shown that thanks to these features, users
consider Emacspeak to be absolutely priceless. Thanks to this
wide-spread user demand, the present version remains priceless
as ever—it is being made available at the same zero-cost as
previous releases.

At the same time, Emacspeak continues to innovate in the area of
eyes-free social interaction and carries forward the
well-established Open Source tradition of introducing user
interface features that eventually show up in luser environments.

On this theme, when once challenged by a proponent of a crash-prone
but well-marketed mousetrap with the assertion "Emacs is a system from
the 70's", the creator of Emacspeak evinced surprise at the unusual
candor manifest in the assertion that it would take popular
idiot-proven interfaces until the year 2070 to catch up to where the
Emacspeak audio desktop is today. Industry experts welcomed this
refreshing breath of Courage Certainty and Clarity (CCC) at a time
when users are reeling from the Fear Uncertainty and Doubt (FUD)
unleashed by complex software systems backed by even more convoluted
press releases.

## 5 Independent Test Results:

Independent test results have proven that unlike some modern (and
not so modern) software, Emacspeak can be safely uninstalled without
adversely affecting the continued performance of the computer. These
same tests also revealed that once uninstalled, the user stopped
functioning altogether. Speaking with Aster Labrador, the creator of
Emacspeak once pointed out that these results re-emphasize the
user-centric design of Emacspeak; "It is the user –and not the
computer– that stops functioning when Emacspeak is uninstalled!".

### 5.1 Note from Aster,Bubbles and Tilden:

UnDoctored Videos Inc. is looking for volunteers to star in a
video demonstrating such complete user failure.

## 6 Obtaining Emacspeak:

Emacspeak can be downloaded from GitHub –see

## Augmented Headphone Listening On Linux For The Emacspeak Audio Desktop

## 1 Executive Summary

A combination of ALSA, Ladspa and OpenAL can provide an enhanced
headphone listening experience on Linux — this article summarizes
various tools and techniques for leveraging these affordances on the
Emacspeak Audio Desktop.

## 2 Glossary

ALSA
  Advanced Linux Sound Architecture. This is my prefered means of controlling audio, and I entirely avoid Pulseaudio on all my machines.
Ladspa
  Linux Audio Developer's Simple Plugin API. Enables the injection of Digital Signal Processing (DSP) when playing media. It is a layer that sits above ALSA. Ladspa filters can be used by user-space applications like MPlayer and SoX when playing media. They can also be used within the user's ASoundRC to define virtual audio devices that inject DSP plugins into the media stream.
OpenAL
  OpenAL is an API for enabling cross-platform 3D audio. User-space applications like MPlayer can use OpenAL as the audio output driver — note that OpenAL on Linux writes to ALSA under the covers.

## 3 Playing Media Using MPlayer

1. With Ladspa and its associated plugins installed — at the minimum
   I would recommend installing `tap-plugins`, module
   `emacspeak-m-player` provides a number of affordances for
   interactively applying Ladspa filters. See commands
   emacspeak-m-player-apply-reverb-preset_(bound to _P in `M-Player`)
   and command emacspeak-m-player-add-filter (bound to f in
   `M-Player`).
2. Command emacspeak-m-player-apply-reverb-preset lets you pick
   among a total of 42 reverb presets defined by Ladspa module `tap_reverb`.
3. Command emacspeak-m-player-add-filter lets you add some of the
   more commonly used Ladspa effects with smart minibuffer
   prompts. Use tab completion to discover some of the predefined
   filters — these are just convenience shortcuts — and you can
   add any filters you use commonly to this list.
4. Note that `mplayer` also has its own
   HRTF filter, but that filter requires that the stream being played is
   a 48K stream.
5. Command emacspeak-m-player-using-openal bound by default to
   Hyper ; launches `mplayer` with OpenAL as the audio output
   driver — adding the following line

to your _~/.alsoftrc~ file will apply a suitable HRTF filter for
augmented headphone listening.

## 4 Defining Virtual Audio Devices For Use With Soundscapes

I use soundscapes to provide a pleasant auditory background as I work
— see earlier blog article that describes Soundscapes On The
Emacspeak Audio Desktop. Defining virtual ALSA devices that inject
Ladspa plugins into the output processing chain is an elegant means
for enhancing the auditory experience provided by these
soundscapes. In this instance, I apply one of the predefined reverb
effects (Ambiance) from Ladspa module `tap-plugins` and pass the
results through a BS2B (Bauer Stereo To Binaural) filter — see file
scapes/ladspa-asoundrc in the emacspeak Github Repo. Notice that that
file defines a number of virtual audio devices and can serve as a
template for injecting any installed Ladspa plugins — you can first
experiment with filters using Emacspeak's Laudible module to find
settings that work for you before applying them via a virtual device
defined in your `asoundrc` file. Finally, you can customize option
`soundscape-manager-options` to add –device <devicename> to have
the soundscapes use the desired virtual device.

## 5 Summary

Laptops today have plenty of processing power and some really nice
audio hardware. Linux has a powerful audio processing stack in ALSA,
Ladspa and OpenAL. Connecting the dots can be fun and provide an
enhanced auditory environment.

## Soundscapes On The Emacspeak Audio Desktop

## 1 Executive Summary

Emacspeak module soundscape adds the ability to automatically switch
Soundscapes based on the current buffer. A Soundscape can be any
continuously playing stream of audio; in practice, using nature sounds
that repeat softly in a pseudo-random manner appears to be
effective. Soundscapes are activated based on the currently active
Emacs Major Mode and as a consequence directly mirror the user's
current activity. The present implementation uses Python package
Boodler to generate soundscapes.

## 2 Usage

Note that package `soundscape.el` does not have any Emacspeak
dependencies. See the package documentation for details on installing
and configuring Boodler.

You can experiment with installed Boodler agents using command
`soundscape` and `soundscape-stop`. You can enable and disable
automatic soundscapes using command `soundscape-toggle`. The
currently active default Soundscape theme can be inspected via command
`soundscape-display` — this produces a buffer that lists the
currently defined /major-mode -> Soundscape mapping.

Package `soundscape.el` considers the inheritance relationship among
Emacs major-modes when computing the set of soundscapes to
activate.As an example, eww-mode inherits from special-mode — as
a consequence, two soundscapes (LightWind and BackgroundWaves)
become active when reading Web content.

## 3 Default Major-Mode->Soundscape (Mood) Mapping:

Here is a table showing the mapping of major-mmodes to Soundscape
moods at the time of writing. For readability, I have stripped out the
package-name for these soundscapes.

Soundscape (Mood) | List Of Major Modes
BuddhaLoop | fundamental
LightStorm | special
RainForever | Info help Man Custom messages-buffer
LightWind | comint elfeed-search
TonkSpace | tabulated-list
Cavern | prog
Drip | message gnus-summary gnus-article gnus-group mspools vm-presentation vm mail twittering jabber-roster jabber-chat erc
Still | text
Water | dired
Steady | calendar diary
BackgroundWaves | w3 eww

## 4 Soundscape Research

I implemented package `soundscape.el` to create a platform that would
let me experiment with different tools that aid in
concentration. After using Soundscapes for about a week, I have also
found that it reduces some of the fatigue that results from having to
listen to synthetic text-to-speech for extended periods.
The true value (if any) of this package will be a function of how heavily
I find myself using it six months from now — as a metric, complete
success might mean that in mid-2016, I still have automatic
soundscapes turned on.
As I type this article in Emacs org-mode, I hear the sound of
water-drops falling softly in the background, and I take note
that I have not switched tasks for the entire time I have spent
writing this article.

Other success metrics — harder to measure — might include how
effective Soundscapes are in helping the user stay focused on a
given activity for extended periods of time. In an ever-connected
world buzzing with a constant stream of distractions ranging from
incoming email and instant-messages to a flood of twitter updates,
this is likely the most relevant metric.

## A Ladspa Work-Bench For The Emacspeak Desktop

# A Ladspa Work-Bench For The Emacspeak Audio Desktop

## 1 Executive Summary

Module `ladspa.el` in the Emacspeak GitHub repository implements a
high-level interface for experimenting with Ladspa Plugins using
`MPlayer` and `SoX`.

## 2 Module `ladspa.el`

This module implements the following functionality:

1. Builds up a table of installed Ladspa plugins along with their
   associated metadata.
2. Command `M-x ladspa` displays installed Ladspa Plugins in a
   special `*Ladspa*` buffer.
3. Plugins can be instantiated by pressing `RET`.
4. Instantiating a plugin prompts for its arguments and displays the
   instantiated plugin in a new buffer.
5. This plugin can then be applied to a running `MPlayer` media
   stream by pressing `a`.
6. The effect can be deleted by pressing `d`.
7. Plugin parameters can be edited by pressing `e` with point on
   the parameter to edit.

## 3 Interfacing With SoX

Module `sox.el` implements an Audio Workbench using `SoX`. Module
`ladspa.el` integrates with that module by allowing the addition of
`ladspa` as a supported SoX effect. Adding a `ladspa` effect results
in a completion interface for picking one of the available Ladspa
plugin; once selected, that plugin then prompts for its parameters as
needed.

## Generating Spatialized Auditory Icons Using MPlayer And Ladspa

## 1 Executive Summary

The Emacspeak GitHub repository now includes a new auditory icon theme
`pan-chimes` — these are the result of spatializing theme `chimes`.

## 2 Fun With Ladspa, MPlayer and Library `tap-plugins`

Here is the result of some fun with MPlayer and Ladspa over the
Thanksgiving weekend. Package `tap-plugins` provides a number of
interesting Ladspa plugins; one of these, `tap_reverb` is used in
module `emacspeak-m-player` to provide a variety of predefined
effects.

Library `tap-plugins` also includes Ladspa filter `tap_autopan` that
pans the input audio signal — see that plugin's documentation for
details.

The Linux media player `mplayer` allows the injection of `ladspa
plugins` in its processing chain.
Combining these, I have created theme `pan-chimes` that provides a
spatialized version of sound-theme `chimes`.

See script `apply-pan.sh` in the Github repository to see how this new
theme was generated.

## Listening To Multiple Media Streams On The Emacspeak Audio Desktop

## 1 Executive Summary

The GitHub version of Emacspeak now supports launching and controlling
multiple media streams. This enables one to listen to the news while
playing a music stream, or relaxing nature sounds.

## 2 Sample Usage

Here are some examples of using this feature:

1. Launch your favorite news station — BBC World Service in my
   case — C-e ; RET.
2. Place the News on the left channel — C-e ; (.
3. Persist the currently playing News stream by invoking command
   emacspeak-m-player-persist-stream bound to C-e ; \. This lets
   you launch a second stream via Emacspeak media key C-e ; rather
   than controlling the currently playing stream.
4. Launch a classical music media-stream — C-e ; lu RET for a lullaby
   media stream.
5. Now Emacspeak M-Player commands will control the most recently
   launched stream; you can once again invoke command
   emacspeak-m-player-persist-stream if you wish.
6. The previously launched (and still playing) News stream is now in a
   buffer named `*Persistent-...*`. Command
   emacspeak-wizards-view-buffers-filtered-by-m-player-mode can be
   used to list buffers that hold a live `m-player` instance. It is
   bound to b in `emacspeak-m-player-mode`. I also bind this command
   to C-; ; in my global keymap.
7. You can make an M-Player instance current by switching to its
   buffer and invoking command emacspeak-m-player-restore-process
   bound to / in `emacspeak-m-player-mode`.

## Emacspeak 43.0 (SoundDog) Unleashed!

# Emacspeak 43.0—SoundDog—Unleashed!

For Immediate Release:

San Jose, Calif., (Nov 20, 2015)
Emacspeak: Redefining Accessibility In The Era Of Internet Computing
–Zero cost of Ownership makes priceless software Universally affordable!

Emacspeak Inc (NASDOG: ESPK) --http://emacspeak.sf.net/– announces the
immediate world-wide availability of Emacspeak 43.0 (SoundDog) –a
powerful audio desktop for leveraging today's evolving data, social
and service-oriented Internet cloud.

## 1 Investors Note:

With several prominent tweeters expanding coverage of
#emacspeak, NASDOG: ESPK has now been consistently trading over
the social net at levels close to that once attained by DogCom
high-fliers—and as of Nov 2015 is trading at levels close to
that achieved by once better known stocks in the tech sector.

## 2 What Is It?

Emacspeak is a fully functional audio desktop that provides
complete eyes-free access to all major 32 and 64 bit operating
environments. By seamlessly blending live access to all aspects
of the Internet such as Web-surfing, blogging, social computing
and electronic messaging into the audio desktop, Emacspeak
enables speech access to local and remote information with a
consistent and well-integrated user interface. A rich suite of
task-oriented tools provides efficient speech-enabled access to
the evolving service-oriented social Internet cloud.

## 3 Major Enhancements:

- Multiple spatially located TTS streams for efficient communication. 🕪
- Refactored, improved sound themes.℗
- Updated org-mode support. 🎶
- Speech-enables package `helm`.𝍎
- Speech-enable package `yasnippet` for smart templates. ䷾
- Context-sensitive keyboard shortcuts via package `emacspeak-muggles`. ⌨
- Speech-enables `lua-mode` for LUA programming.
- Speech-enable package `projectile` for software project

management. 📽

- Speech-enable package `slime` for Lisp programming. Λ
- Updated Librivox support to the new API. 📖
- Package `XBacklight` for controlling LCD brightness. ⎚
- Updated NPR client for one-click access to present and past NPR content.📻
- BBC radio programs via IPlayer and friends. 📢
- Emacs EWW: Consume Web content efficiently. 🕷
- Updated Info manual 🕮
- Speech-enabled Elfeed, an Emacs Feed Reader 🗞
- emacspeak-url-templates: Smart Web access. ♅
- emacspeak-websearch.el Find things fast. ♁
- And a lot more than wil fit this margin. …

## 4 Establishing Liberty, Equality And Freedom:

Never a toy system, Emacspeak is voluntarily bundled with all
major Linux distributions. Though designed to be modular,
distributors have freely chosen to bundle the fully integrated
system without any undue pressure—a documented success for
the integrated innovation embodied by Emacspeak. As the system
evolves, both upgrades and downgrades continue to be available at
the same zero-cost to all users. The integrity of the Emacspeak
codebase is ensured by the reliable and secure Linux platform
used to develop and distribute the software.

Extensive studies have shown that thanks to these features, users
consider Emacspeak to be absolutely priceless. Thanks to this
wide-spread user demand, the present version remains priceless
as ever—it is being made available at the same zero-cost as
previous releases.

At the same time, Emacspeak continues to innovate in the area of
eyes-free social interaction and carries forward the
well-established Open Source tradition of introducing user
interface features that eventually show up in luser environments.

On this theme, when once challenged by a proponent of a crash-prone
but well-marketed mousetrap with the assertion "Emacs is a system from
the 70's", the creator of Emacspeak evinced surprise at the unusual
candor manifest in the assertion that it would take popular
idiot-proven interfaces until the year 2070 to catch up to where the
Emacspeak audio desktop is today. Industry experts welcomed this
refreshing breath of Courage Certainty and Clarity (CCC) at a time
when users are reeling from the Fear Uncertainty and Doubt (FUD)
unleashed by complex software systems backed by even more convoluted
press releases.

## 5 Independent Test Results:

Independent test results have proven that unlike some modern (and
not so modern) software, Emacspeak can be safely uninstalled without
adversely affecting the continued performance of the computer. These
same tests also revealed that once uninstalled, the user stopped
functioning altogether. Speaking with Aster Labrador, the creator of
Emacspeak once pointed out that these results re-emphasize the
user-centric design of Emacspeak; "It is the user –and not the
computer– that stops functioning when Emacspeak is uninstalled!".

### 5.1 Note from Aster,Bubbles and Tilden:

UnDoctored Videos Inc. is looking for volunteers to star in a
video demonstrating such complete user failure.

## 6 Obtaining Emacspeak:

Emacspeak can be downloaded from GitHub –see

## Using Multiple TTS Streams On The emacspeak Audio Desktop

## 1 Executive Summary

Emacspeak now uses multiple text-to-speech streams — as an example,
this enables spoken notifications that do not interrupt ongoing spoken
output. To make such notifications more perceivable, Emacspeak places
notifications to the right of the user by leveraging Linux-ALSA
features that allow one to scale the amplitude of the left and right
audio channels.

## 2 Background

Until now, Emacspeak has used a single instance of a Text-To-Speech
(TTS) engine to produce all spoken feedback. An unfortunate
consequence is that any spoken announcement necessarily interrupts
ongoing speech; as an example, an incoming instant-message (e.g.,
Jabber notification) can interrupt what you're currently
reading.

Emacs itself produces a large number of asynchronous messages
depending on the number of processes running within Emacs; at present,
all Emacs generated messages are equal though there are ongoing
plans to improve this situation going forward, e.g., using package
`alert`. With Emacspeak now able to use multiple TTS streams, arrival
of package `alert` within Emacs should facilitate smarter handling of
different categories of messages over time.

Playing multiple TTS streams simultaneously can make it hard to
understand the resulting output; Emacspeak leverages underlying ALSA
functionality to send notifications to a virtual ALSA device that
places the auditory output mostly on the right channel. See the
following paragraphs on setup/configuration. I'm presently using this
on Linux with the `linux-outloud` voice — you need to have a copy of
this TTS engine installed and working — see Voxin for details on
obtaining that engine. Note: the Emacspeak `espeak` server does not
use raw ALSA for its output — consequently, notifications produced
by `espeak` play on both left and right channels, making it
impossible to understand. The `mac` server may be able to support
this functionality using something Mac-specific — patches welcome.

## 3 Emacspeak Setup

- Emacspeak now adds user-option
  `emacspeak-tts-use-notify-stream`. If this is set to `t` in the
  user's initialization file before Emacspeak is loaded, Emacspeak
  checks to see if the user's selected TTS engine supports multiple
  instances, and if so launches a second instance of the TTS engine
  for use as a Notification TTS Stream. See my
  `tvr/emacs-startup.el` in the Emacspeak Git Repository for an
  example setup.
- The Notification TTS Stream can be restarted via command
  `dtk-notify-initialize` bound to `C-e d C-n`. You should
  ordinarily not need to invoke this command.
- The Notification TTS Stream can be shut-down using command
  `dtk-notify-shutdown` bound to `C-e d C-s`. When the /Notification
  TTS Stream is not available, Emacspeak defaults to using a single
  TTS stream for all spoken output — i.e., no change.
- At present, emacspeak tries to use a separate Notification TTS
  Stream when the selected TTS engine is a software TTS
  running locally.
- File `servers/linux-outloud/notify-asoundrc` contains the
  `.asoundrc` that I am using on my thinkpad. To have Emacspeak
  place the Notification TTS Stream mostly on the right, the
  contents of that file (suitably modified for your sound card)
  need to be placed in file `$HOME/.asoundrc`. Warning: Handle with
  care — a broken `.asoundrc` can kill all audio output.
- The `.asoundrc` scales left and right amplitude to place the
  output mostly on the right — to change this behavior, you can
  edit the Transformation Table for virtual device `tts_mono` in
  the `.asoundrc` file.
- This set-up has not been tested with `pulseaudio`.

## Smart Actions In Directory Buffers For The Emacspeak Audio Desktop

## 1 Overview

Emacspeak now provides a smart actions feature in Emacs' Directory
Editor (DirEd) buffers.
Pressing key `Ctrl-RET` in `DirEd` buffers now invokes
an appropriate Emacspeak action on the current file.

## 2 Background

Over time, Emacspeak has come to include a number of smart handlers
for different file types:

- An MPlayer interface for media files.
- An EPub reader for electronic books.
- A light-weight PDF viewer.
- A table browser for `csv` files.

Command `emacspeak-dired-open-this-file` bound to `Ctrl-RET` in
`DirEd` buffers unifies this functionality by invoking the appropriate
Emacspeak action on the file on the current line.

## 3 Extending To `*Locate*` Buffers

This facility is also available in `locate-mode`
buffers. Emacspeak provides two content-specific
Locate commands:

- Command `emacspeak-m-player-locate (I have this bound to key
  ~Super-l`) for locating media files that match a pattern.
- Command `emacspeak-epub-locate-epub` bound to `l` in EPub
  Interaction for locating `epub` files.

Pressing key `Ctrl-RET` in the resulting `*Locate*` buffers invokes
the afore-mentioned smart action.

## Emacspeak: An Overview Of Voice-Lock Over The Years

## 1 Executive Summary

Audio formatted output is provided via `voice-lock` in Emacspeak.
The feature was originally implemented in 1994 and significantly
overhauled in 2002 (with no change in functionality). Now, in 2015,
the implementation has been reworked to be once again simpler — but
with the same functionality.

## 2 1994: Original Implementation

Font-lock was a new feature in Emacs 19 — it was introduced right
around the time the Emacspeak project was started.
At the time, there were multiple font-lock packages in
Emacs. Emacspeak implemented `voice-lock` via a stand-alone module
that attached property `personality` to buffer contents. The
`dtk-speak` Text-To-Speech module treated strings annotated with
property `personality` as an aural display list when producing
spoken output.

In the winter of 1995, I implemented Aural CSS in emacspeak, and
this resulted in module `acss.el` — that module provides a clean
abstraction for defining values that can be assigned to property
`personality`. Next, the rest of emacspeak was overhauled to
express all `voice-lock` features via the ACSS abstraction.

## 3 2002 Overhaul

With feature `font-lock` now mature, Emacs itself converged on a
single font-lock module with `jit-lock.el` providing just-in-time font
locking. This meant that Emacspeak's `voice-lock` feature could now be
more easily implemented by attaching appropriate advice to lisp
functions `put-text-property` and friends — this led to the deletion
of module `voice-lock.el` and the creation of module
`emacspeak-personality.el`.

That module provided multiple options for how faces were mapped to
personalities:

- Cumulative where property `personality` was either appended or
  prepended to the list of personalities at any given position.
- Simple: where the new personality directly replaced any previously
  applied `personality` property.
- None: Where faces were not mapped to personalities.

## 4 2015 Overhaul

And now, in 2015, the code in module `dtk-speak.el` that implements
audio-formatting has been overhauled to directly map faces to
personalities. This implementation can be enabled by setting the
option `emacspeak-personality-voiceify-faces` provided in module
`emacspeak-personality.el` to All. This means that the new
implementation can co-exist (at least for a while) with the earlier
advice-based implementation from module `emacspeak-personality.el`.

once deemed to be stable, the new implementation will become the
default — by changing the default value of
`emacspeak-personality-voiceify-faces` to none.

## 5 Summary

From an end-user's perspective, nothing has changed in 21 years. From
the perspective of implementing voice-lock for Emacs modules, nothing
has changed — all that an Emacspeak extension for a specific package
needs to do to enable `voice-lock` is to set up a face->personality
mapping as before via function `voice-setup-add-map`. Note that
property `personality` will continue to have higher precedence than
property `face` with respect to the audio formatting that gets applied
i.e. Emacspeak first consults value of property `personality`, and if
that is not set, but there is a `face` property set, then that
face->personality mapping (if defined) is used as the aural style.

## Emacspeak:Setting up StumpWM as a speech-enabled Window Manager.

# Emacspeak support for StumpWM

## 1 Summary:

Describes my Linux X-Windowing setup using lightdm to initialize the desktop and StumpWM configured as a talking Window Manager.
These files can be found under `emacspeak/stumpwm` in your Emacspeak installation, or in the source code cloned from https://github.com/tvraman/emacspeak.

## 2 Overview

File `stumpwmrc` is my StumpWM init file that I use to set up
StumpWM as a talking window manager. With this setup, I run Emacs in
one window and Chrome+ChromeVox in another window.

File `xsession` is my `.xsession` file — it launches StumpWM once `lightdm` has finished authentication.
You can find my `lightdm` setup files in directory `emacspeak/tvr/lightdm`.

## 3 Contents

tts.lisp
  Interface to Emacspeak TTS servers.
stumpwmrc
  Code to insert into personal =.stumpwmr
xsession-
  My= .xsession= file.
xlock
  A light-weight screen-lock script.

## 4 Resulting Functionality

To set this up, You should only need to edit the value of
`*emacspeak-dir*` in the `stumpwmrc` file for setup.

1. All Keybindings match my usual `screen` setup, including the window-manager prefix-key.
2. C-\ is the window-manager key.
3. Switching windows speaks the title of the new window.
4. Stumpwm command for displaying window list `C-\w` also speaks the output.
5. The init file provides a simple lock-screen command bound to `C-\d`.
6. The above lock command invokes shell script `xlock` — that script takes care of playing an auditory icon when the desktop is locked or unlocked.
7. Window manager messages speak automatically; this can be toggled with `C-\t`.
8. If there is a lot of activity in a window that is not focused,
   you can turn off automatic speaking of messages using `C-\t` to
   avoid distraction.
9. StumpWM is set up to deny raise-focus requests — this is so that activity in a window doesn't automatically grab focus.
   I typically run with only one window displayed at a time.

## Setting Up An X Environment For Using With Emacspeak, ChromeVox and StumpWM

## 1 Executive Summary

This is a follow-up to the article on my Window Manager set-up
and details the setup of my X environment. This setup is specifically geared around the following use-cases:

1. Emacspeak running in a window to provide a local audio desktop.
2. ChromeVox running in a second window to provide access to JS-powered WebApps. Note that for the content-oriented Web, I use Emacs' built-in EWW browser.
3. SSH running in an XTerm to my remote Linux desktop in a third window. The remote desktop runs Emacspeak and produces auditory feedback through a local speech server.

The setup described below is implemented via my personal `.XResources`
file — that file along with my `.xsession` file that loads it are
both checked into the GitHub repo under `emacspeak/stumpwm` along with any needed helper files.

The remaining sections give a brief descriptive overview of the
`.XResources` and `.xsession` files as they exist at the time of
writing.

## 2 Resulting Functionality: What This Gives Us

1. You can cut-and-paste between the local Chrome and local Emacspeak using standard clipboard copy/paste commands. Make sure Emacs is set up to use the clipboard, and not the primary X selection.
2. Output displayed in the Xterm, e.g., by the remote Emacspeak session, can be brought into the local Emacspeak session by hitting `PrintEverything` bound to `Ctrl-Return` in the XTerm window.
3. Contents of the local clipboard, i.e. Chrome, Emacspeak etc., can be pasted into the remote Emacspeak running in the XTerm using key `Ctrl-Shift-Space`.

## 3 Initializing X Session Via File `.xsession`

    #!/bin/sh
          #Caps Lock is Control
          setxkbmap -option ctrl:nocaps
          #load in XResources to customize X environment
          xrdb -merge $HOME/.Xresources &
          #Display locks after  30 minutes of inactivity
          xautolock -detectsleep -time 30  -locker
          "$HOME/bin/xlock"      &
          # Launch Emacs
          emacs  -title Emacs &
          # XTerm for SSH to remote desktop
          xterm  -title Retriever &
          # StumpWM Setup: Use SBCL
          export LISP=sbcl
          # Export our  X auth environment
          ${HOME}/bin/export_x_info &
          # Launch StumpWM
          exec  /usr/local/bin/stumpwm

## Announcing Emacspeak 42.0 (AnswerDog)

# Emacspeak 42.0—AnswerDog—Unleashed!

## 1 Emacspeak-42.0 (AnswerDog) Unleashed!

** For Immediate Release:

San Jose, Calif., (May 1, 2015) Emacspeak: Redefining Accessibility In The Era Of Internet Computing –Zero cost of upgrades/downgrades makes priceless software affordable!

Emacspeak Inc (NASDOG: ESPK) --http://emacspeak.sf.net– announces the immediate world-wide availability of Emacspeak 42.0 (AnswerDog) –a powerful audio desktop for leveraging today's evolving data, social and service-oriented Internet cloud.

### 1.1 Investors Note:

With several prominent tweeters expanding coverage of #emacspeak, NASDOG: ESPK has now been consistently trading over the social net at levels close to that once attained by DogCom high-fliers—and as of May 2015 is trading at levels close to that achieved by once better known stocks in the tech sector.

### 1.2 What Is It?

Emacspeak is a fully functional audio desktop that provides complete eyes-free access to all major 32 and 64 bit operating environments. By seamlessly blending live access to all aspects of the Internet such as Web-surfing, blogging, social computing and electronic messaging into the audio desktop, Emacspeak enables speech access to local and remote information with a consistent and well-integrated user interface. A rich suite of task-oriented tools provides efficient speech-enabled access to the evolving service-oriented social Internet cloud.

### 1.3 Major Enhancements:

- Emacs EWW: Consume Web content efficiently. 🕷
- Updated Info manual 🕮
- SoX integration for generating auditory feedback ℗
- Speech-enabled Elfeed, an Emacs Feed Reader 🗞
- CSound generated 3d Auditory Icons ⟀
- Audacious — An Audio Workbench using SoX 🝧
- Audio presets for MPlayer using Ladspa filters ♮
- emacspeak-url-templates: Smart Web access. ♅
- Integrated TuneIn Radio search, browse and play 📻
- emacspeak-websearch.el Find things fast. ♁
- Calibre integration for searching and viewing epub 📚 📔
- Complete anything via company integration ∁
- Emacs 24.4: Supports all new features in Emacs 24.4. 🌚
- And a lot more than wil fit this margin. …

### 1.4 Establishing Liberty, Equality And Freedom:

Never a toy system, Emacspeak is voluntarily bundled with all major Linux distributions. Though designed to be modular, distributors have freely chosen to bundle the fully integrated system without any undue pressure—a documented success for the integrated innovation embodied by Emacspeak. As the system evolves, both upgrades and downgrades continue to be available at the same zero-cost to all users. The integrity of the Emacspeak codebase is ensured by the reliable and secure Linux platform used to develop and distribute the software.

Extensive studies have shown that thanks to these features, users consider Emacspeak to be absolutely priceless. Thanks to this wide-spread user demand, the present version remains priceless as ever—it is being made available at the same zero-cost as previous releases.

At the same time, Emacspeak continues to innovate in the area of eyes-free social interaction and carries forward the well-established Open Source tradition of introducing user interface features that eventually show up in luser environments.

On this theme, when once challenged by a proponent of a crash-prone but well-marketed mousetrap with the assertion "Emacs is a system from the 70's", the creator of Emacspeak evinced surprise at the unusual candor manifest in the assertion that it would take popular idiot-proven interfaces until the year 2070 to catch up to where the Emacspeak audio desktop is today. Industry experts welcomed this refreshing breath of Courage Certainty and Clarity (CCC) at a time when users are reeling from the Fear Uncertainty and Doubt (FUD) unleashed by complex software systems backed by even more convoluted press releases.

### 1.5 Independent Test Results:

Independent test results have proven that unlike some modern (and not so modern) software, Emacspeak can be safely uninstalled without adversely affecting the continued performance of the computer. These same tests also revealed that once uninstalled, the user stopped functioning altogether. Speaking with Aster Labrador, the creator of Emacspeak once pointed out that these results re-emphasize the user-centric design of Emacspeak; "It is the user –and not the computer– that stops functioning when Emacspeak is uninstalled!".

#### 1.5.1 Note from Aster,Bubbles and Tilden:

UnDoctored Videos Inc. is looking for volunteers to star in a video demonstrating such complete user failure.

### 1.6 Obtaining Emacspeak:

Emacspeak can be downloaded from GitHub –see https://github.com/tvraman/emacspeak you can visit Emacspeak on the WWW at http://emacspeak.sf.net. You can subscribe to the emacspeak mailing list emacspeak@cs.vassar.edu by sending mail to the list request address emacspeak-request@cs.vassar.edu. The Emacspeak Blog is a good source for news about recent enhancements and how to use them.

The latest development snapshot of Emacspeak is always available via Git from GitHub at Emacspeak GitHub .

## HowTo: Log Speech Server Output To Aid In Developing TTS Servers

# HowTo: Log TTS Server Output To Aid In TTS Server Development

## 1 HowTo: Log TTS Server Output To Aid In TTS Server Development

This is mostly of interest to developers of Emacspeak speech servers. This article outlines how one can log TTS server output to a file. The loggeds record all commands send by Emacspeak to the TTS server. It is best to generate the logs in an Emacs session that is separate from the Emacs session where you are developping your code. This keeps the logs short, and makes isolating problems much easier.

### 1.1 How It Works

The emacspeak/servers directory now contains log_<tts-name> servers for the various supported speech servers. When selected, these log-speech servers produce no speech output; instead, they output the speech server commands received from Emacspeak to a file in /tmp named tts-log-$$. Once you're done logging, you can examine this file from the primary Emacs session.

### 1.2 Typical Workflow

Assume you want to see the speech-server commands sent by Emacs when you perform a specific action, in this instance, pressing C-e m to execute command emacspeak-speak-mode-line.

1. In a separate Linux console or X-Window, launch Emacs with Emacspeak loaded — this is separate from your primary Emacs session.
2. In this Emacs session, use C-e d d (command dtk-select-server) and select log-<tts-name> as the speech server, where tts-name corresponds to the speech engine you're testing.
3. Emacspeak will now start the logging server, and fall silent; all commands sent by Emacspeak to the speech-server will be logged to a file in /tmp.
4. Press C-e m – to produce the log output you want to see.
5. Use command _emacspeak-emergency-tts-restart to get speech back.
6. Open a dired buffer on /tmp, press s to sort files by date, and find your generated log output at the top of the list.
7. Note: It is useful to configure your default speech engine via Custom – see user option emacspeak-emergency-tts-server. It provides a quick-fire means to get speech back if you ever switch to a speech-server that fails for some reason.

## Emacspeak Development Is Moving To GitHub

## 1 Summary:

Emacspeak development is moving from Google Code Hosting to GitHub. If you have been running from the SVN repository, I recommend you switch to the GitHub version by executing:

          git clone https://github.com/tvraman/emacspeak.git
          make config
          make -j

- If using Outloud TTS:

          cd servers/linux-outloud  &&  make

- If using Espeak TTS:

          cd servers/linux-espeak && make

- After this, all you should need to stay up to date is a periodic

          git pull; make config; make

## 2 A Brief History

- The first five years of Emacspeak development used a local RCS repository on my home machine (1994 –1999).
- The first few releases of Emacspeak were distributed through the Web site and FTP server at Digital Research; they were also mirrored at Cornell.
- After moving to Adobe Systems in the fall of 1995, Emacspeak was distributed exclusively through my Web page on the Cornell CS Department Web server, which also hosted my personal Web site.
- In 2000, I created Emacspeak On SourceForge

and used that site for both hosting the Emacspeak source code as well as the Web site — coincidentally, I lost the ability to update my Web site at Cornell CS around the same time.

- Over time it became harder and harder to publish new Emacspeak releases through the SourceForge interface. Luckily, Google Code Hosting came along a few months after I joined Google, and moving the source code repository to Google Code SVN was a no-brainer.
- My friend and colleague Fitz helped me migrate the 5+ years of CVS history to SVN; this meant that the source code repository on Google Code also recorded all of the development history that had been built up on Sourceforge.
- Now, it's time to move to GitHub. I've been using Git for most of my work the last few years, but was simply too lazy to move Emacspeak development from SVN to Git on GoogleCode.
- But over time, the advantages present in Git as a source control system and GitHub as a hosting service have increased — primary among these — a rich set of Emacs tools that have been written to leverage the GitHub API.
- For Git integration in Emacs, my personal preference is package Magit available through Elpa —

          M-x package-install magit in Emacs.

- The GitHub Web site itself is fairly heavy-weight in terms of its use of scripting, i.e. performing all operations through the github.com Web site from within Emacs is fairly unpleasant. But the afore-mentioned GitHub API makes this a non-issue at this point with respect to the type of workflow I prefer.
- So this week, I did the work to migrate Emacspeak development to Emacspeak On GitHub.

## 3 Status Of Migration

- With help from some of the kind folk at Google Code Hosting, I've successfully migrated the source code repository including all release tags to GitHub.
- I am now checking in changes into GitHub; the SVN repository on Google Code Hosting is now frozen, and I do not plan to make any commits there.
- I presently have no immediate plans to start using features of GitHub like the Issue Tracker; for now we will continue to use the Emacspeak mailing list which has served us well for 20 years.
- I have also taken this opportunity to prune out legacy portions of the Emacspeak codebase by moving modules to obsolete at each level of the directory tree.
- Since starting the Emacspeak Blog in late 2005, I have published a sequence of articles describing Emacspeak features and usage patterns; I felt that having these articles for local reference made a useful supplement to the emacspeak online documentation. Toward this end, I have downloaded all articles published so far and checked in both XML and HTML versions into sub-directory blogs.
- Note that newer articles are also available as .org files under sub-directory announcements.

## 4 Next Steps

- I still need to learn how to do software releases on GitHub.

Share And Enjoy!

## Enhanced Audio On The Emacspeak Desktop

## 1 Enhanced Audio On The Emacspeak Desktop

I recently added a set of modules to Emacspeak to leverage some of the high-end audio functionality available on Linux machines on modern hardware. As an example, applying effects such as 3D spatialization, high-end reverb effects etc. once consumed CPU cycles to the extent where it was not possible to play with these in realtime. All these now take less than 1–5% of the CPU, and that when my laptop is running in power-save mode!

### 1.1 An Audio Workbench Using SoX

Sound Exchange (SoX), described as the Swiss army knife of sound processing, has been around since the time I was a graduate student. Today it provides a versatile set of tools for editing and manipulating both wave and mp3 files. Module sox.el implements a simple Audio Workbench for the Emacspeak desktop.

#### 1.1.1 Pre-Requisites

SoX with all available auxillary packages for adding support for various filetypes such as mp3. The various Ladspa related packages for installing additional audio effect filters.

#### 1.1.2 Usage Instructions For SoX.el

- Launch the Audio Workbench via by executing M-x sox.
- Use f to open a wave or mp3 file you wish to manipulate.
- Add any of the supported effects using e.
- Use upper-case E to add more than one effect.
- Hit p to play the result, s to save the result to a new file.

At present sox.el supports a few effects such as trim for clipping files, reverb for adding a reverb etc., with more to come as I use it.

### 1.2 Adding High-End Reverb When Playing Media Streams

I use mplayer to play both local and network media streams. MPlayer can apply a wide range of filters to the audio stream; more interestingly it can also apply effects implemented as Ladspa plugins. Package tap-plugins implements a large number of high-quality Ladspa filters, including a versatile Reverb filter.

Once you have package tap-plugins and its dependenciesinstalled, and a relatively new version of MPlayer (with support for Ladspa plugins), you can now apply various Reverb Presets to your media streams via Emacspeak MPlayer command emacspeak-m-player-apply-reverb-preset bound to P in Emacspeak MPlayer. Package tap-plugins defines a total of 42 Reverb Presets, experiment with these when wearing headsets. Once you have applied a Reverb Preset, you can edit its current settings via command emacspeak-m-player-edit-reverb bound to R in Emacspeak MPlayer. Alternatively, you can pick a default effect to use via Emacs' custom interface; see option emacspeak-m-player-reverb-filter.

### 1.3 Defining Convenient MPLayer Shortcuts

Finally, You can now bind shortcut keys for launching Emacspeak MPlayer from specific locations where you store media, e.g., you can have separate shortcuts for Music vs Audio Books – see command emacspeak-m-player-accelerator. This is best used by customizing Emacspeak option emacspeak-media-location-bindings — just use the Customize interface to specify pairs of shortcut keys and media locations.

## Internet Radio: Tune-In For Emacspeak

## 1 Internet Radio: Tune-In For Emacspeak

I just checked in the ability to browse, search and play radio-stations from TuneIn on the Emacspeak Audio Desktop.

### 1.1 Pre-Requisites

1. xsltproc for xsl stylesheet processing.
2. Linux mplayer for playing streams, preferably the latest version

## 2 Simple Usage Summary

- M-x emacspeak-wizards-tune-in-radio-browse brings up the browse interface.
- M-x emacspeak-wizards-tune-in-radio-search prompts for a query and brings up search results.
- Both browse and search get the results back as an OPML feed, which gets displayed as a simple Web page within the Emacs Web Browser (EWW if using 24.4).
- Items identified as (link) are themselves OPML feeds and can be opened via command emacspeak-feeds-opml-display.
- The initial browse buffer is set up to use opml-display when you click on link items.
- You can play (audio) links by invoking command emacspeak-webutils-play-media-at-point — this command is bound to _; in EWW.
- You need to provide an interactive prefix argument to the above command to indicate that it is a playlist — so you actually press C-u ; on audio links.
- Many of the audio links do not return a playlist – they instead return a link that is a pointer to a playlist. Newer versions of mplayer will throw a security error — you can tell mplayer to follow them by invoking the earlier command with two prefix args so C-u C-u ;.
- All this works about 90% of the time. In some cases – depending on whether the server failed to generate the right

mimetype for the play URL etc, you may need to run

          curl --silent <url>

where <url> is the URL of the audio link, then pass that resulting URL to command emacspeak-m-player-url.

## 3D: A Spatial Auditory Icon Theme Generated Using CSound

## Using CSound To Generate Auditory Icons

### 1 Auditory Icon Theme: 3d

CSound is a sophisticated music sound synthesis system with a strong community of developers. I've played off and on with CSound ever since the early 90's and have always been intrigued by the possibility of algorithmically creating new auditory icon themes for Emacspeak using CSound.

Over the holidays last December, I finally got around to creating my first complete CSound-generated auditory icon theme – it is now checked into Emacspeak SVN as theme 3d. This theme is best experienced with headphones — many of the generated icons use spatial audio to good effect.

## Announcing Emacspeak 41.0: NiceDog

# Emacspeak 41.0—NiceDog—Unleashed!

## 1 Emacspeak-41.0 (NiceDog) Unleashed!

** For Immediate Release:

San Jose, Calif., (Nov 26, 2014) Emacspeak: Redefining Accessibility In The Era Of Web Computing –Zero cost of upgrades/downgrades makes priceless software affordable!

Emacspeak Inc (NASDOG: ESPK) --http://emacspeak.sf.net– announces the immediate world-wide availability of Emacspeak 41.0 (NiceDog) –a powerful audio desktop for leveraging today's evolving data, social and service-oriented Web cloud.

### 1.1 Investors Note:

With several prominent tweeters expanding coverage of #emacspeak, NASDOG: ESPK has now been consistently trading over the social net at levels close to that once attained by DogCom high-fliers—and as of November 2014 is trading at levels close to that achieved by once better known stocks in the tech sector.

### 1.2 What Is It?

Emacspeak is a fully functional audio desktop that provides complete eyes-free access to all major 32 and 64 bit operating environments. By seamlessly blending live access to all aspects of the Internet such as Web-surfing, blogging, social computing and electronic messaging into the audio desktop, Emacspeak enables speech access to local and remote information with a consistent and well-integrated user interface. A rich suite of task-oriented tools provides efficient speech-enabled access to the evolving service-oriented social Web cloud.

### 1.3 Major Enhancements:

- Emacs EWW: Consume Web content efficiently. 📚
- emacspeak-url-templates: Smart Web access. ♅
- emacspeak-websearch.el Find things fast. ♁
- emacspeak-google.el: Improved Google integration. ⁈
- Calibre integration for searching and viewing epub 📚
- Complete anything via company integration 🗜
- Speech-enabled 2048 🂠
- Emacspeak At Twenty -Historical Overview ⛬
- gmaps.el: Find places, read reviews, get there. 🌐
- Feed Browser Consume feeds post Google-Reader. ␌
- Freebase Search: Explore freebase knowledge base. 🆓
- Emacs 24.4: Supports all new features in Emacs 24.4. 🌚
- And a lot more than wil fit this margin. …

### 1.4 Establishing Liberty, Equality And Freedom:

Never a toy system, Emacspeak is voluntarily bundled with all major Linux distributions. Though designed to be modular, distributors have freely chosen to bundle the fully integrated system without any undue pressure—a documented success for the integrated innovation embodied by Emacspeak. As the system evolves, both upgrades and downgrades continue to be available at the same zero-cost to all users. The integrity of the Emacspeak codebase is ensured by the reliable and secure Linux platform used to develop and distribute the software.

Extensive studies have shown that thanks to these features, users consider Emacspeak to be absolutely priceless. Thanks to this wide-spread user demand, the present version remains priceless as ever—it is being made available at the same zero-cost as previous releases.

At the same time, Emacspeak continues to innovate in the area of eyes-free social interaction and carries forward the well-established Open Source tradition of introducing user interface features that eventually show up in luser environments.

On this theme, when once challenged by a proponent of a crash-prone but well-marketed mousetrap with the assertion "Emacs is a system from the 70's", the creator of Emacspeak evinced surprise at the unusual candor manifest in the assertion that it would take popular idiot-proven interfaces until the year 2070 to catch up to where the Emacspeak audio desktop is today. Industry experts welcomed this refreshing breath of Courage Certainty and Clarity (CCC) at a time when users are reeling from the Fear Uncertainty and Doubt (FUD) unleashed by complex software systems backed by even more convoluted press releases.

### 1.5 Independent Test Results:

Independent test results have proven that unlike some modern (and not so modern) software, Emacspeak can be safely uninstalled without adversely affecting the continued performance of the computer. These same tests also revealed that once uninstalled, the user stopped functioning altogether. Speaking with Aster Labrador, the creator of Emacspeak once pointed out that these results re-emphasize the user-centric design of Emacspeak; "It is the user –and not the computer– that stops functioning when Emacspeak is uninstalled!".

#### 1.5.1 Note from Aster,Bubbles and Tilden:

UnDoctored Videos Inc. is looking for volunteers to star in a video demonstrating such complete user failure.

### 1.6 Obtaining Emacspeak:

Emacspeak can be downloaded from Google Code –see http://code.google.com/p/emacspeak/ You can visit Emacspeak on the WWW at http://emacspeak.sf.net. You can subscribe to the emacspeak mailing list emacspeak@cs.vassar.edu by sending mail to the list request address emacspeak-request@cs.vassar.edu. The Emacspeak Blog is a good source for news about recent enhancements and how to use them. The WowDog release is at http://emacspeak.googlecode.com/svn/wiki/downloads/emacspeak-41.0.tar.bz2. The latest development snapshot of Emacspeak is always available via Subversion from Google Code at http://emacspeak.googlecode.com/svn/trunk/

## 1 Introduction

One afternoon in the third week of September 1994, I started writing myself a small Emacs extension using Lisp Advice to make Emacs speak to me so I could use a Linux laptop. As Emacspeak turns twenty, this article is both a quick look back over the twenty years of lessons learned, as well as a glimpse into what might be possible as we evolve to a world of connected, ubiquitous computing. This article draws on Learning To Program In 10 Years by Peter Norvig for some of its inspiration.

## 2 Using UNIX With Speech Output — 1994

As a graduate student at Cornell, I accessed my Unix workstation (SunOS) from an Intel 486 PC running IBM Screen-Reader. There was no means of directly using a UNIX box at the time; after graduating, I continued doing the same for about six months at Digital Research in Cambridge — the only difference being that my desktop workstation was now a DEC-Alpha. Throughout this time, Emacs was my environment of choice for everything from software development and Internet access to writing documents.

In fall of 1994, I wanted to start using a laptop running Linux; a colleague (Dave Wecker) was retiring his 386mhz laptop that already had Linux on it and I decided to inherit it. But there was only one problem — until then I had always accessed a UNIX machine from a secondary PC running a screen-reader — something that would clearly make no sense with a laptop!

Another colleague, Win Treese, had pointed out the interesting possibilities presented by package advice in Emacs 19.23 — a few weeks earlier, he had sent around a small snippet of code that magically modified Emacs' version-control primitive to first create an RCS directory if none existed before adding a file to version control. When I speculated about using the Linux laptop, Dave remarked — you live in Emacs anyway — why dont you just make it talk!

Connecting the dots, I decided to write myself a tool that augmented Emacs' default behavior to speak — within about 4 hours, version 0.01 of Emacspeak was up and running.

## 3 Key Enabler — Emacs And Lisp Advice

It took me a couple of weeks to fully recognize the potential of what I had built with Emacs Lisp Advice. Until then, I had used screen-readers to listen to the contents of the visual display — but Lisp Advice let me do a lot more — it enabled Emacspeak to generate highly context-specific spoken feedback, augmented by a set of auditory icons. I later formalized this design under the name speech-enabled applications. For a detailed overview of the architecture of Emacspeak, see the chapter on Emacspeak in the book Beautiful Code from O'Reilly.

## 4 Key Component — Text To Speech (TTS)

Emacspeak is a speech-subsystem for Emacs; it depends on an external Text-To-Speech (TTS) engine to produce speech. In 1994, Digital Equipment released what would turn out to be the last in the line of hardware DECTalk synthesizers, the DECTalk Express. This was essentially an Intel 386with 1mb of flash memory that ran a version of the DECTalk TTS software — to date, it still remains my favorite Text-To-Speech engine. At the time, I also had a software version of the same engine running on my DEC-Alpha workstation; the desire to use either a software or hardware solution to produce speech output defined the Emacspeak speech-server architecture.

I went to IBM Research in 1999; this coincided with IBM releasing a version of the Eloquennce TTS engine on Linux under the name ViaVoice Outloud. My colleague Jeffrey Sorenson implemented an early version of the Emacspeak speech-server for this engine using the OSS API; I later updated it to use the ALSA library while on a flight back to SFO from Boston in 2001. That is still the TTS engine that is speaking as I type this article on my laptop.

20 years on, TTS continues to be the weakest link on Linux; the best available solution in terms of quality continues to be the Linux port of Eloquence TTS available from Voxin in Europe for a small price. Looking back across 20 years, the state of TTS on Linux in particular and across all platforms in general continues to be a disappointment; most of today's newer TTS engines are geared toward mainstream use-cases where naturalness of the voice tends to supersede intelligibility at higher speech-rates. Ironically, modern TTS engines also give applications far less control over the generated output — as a case in point, I implemented Audio System For Technical Readings (AsTeR) in 1994 using the DECTalk; 20 years later, we implemented MathML support in ChromeVox using Google TTS. In 2013, it turned out to be difficult or impossible to implement the type of audio renderings that were possible with the admittedly less-natural sounding DECTalk!

## 5 Emacspeak And Software Development

Version 0.01 of Emacspeak was written using IBM Screen-Reader on a PC with a terminal emulator accessing a UNIX workstation. But in about 2 weeks, Emacspeak was already a better environment for developing Emacspeak in particular and software development in general. Here are a few highlights in 1994 that made Emacspeak a good software development environment, present-day users of Emacspeak will see that that was just scratching the surface.

- Audio formatting using voice-lock to provide aural syntax highlighting.
- Succinct auditory icons to provide efficient feedback.
- Emacs' ability to navigate code structurally —

as opposed to moving around by plain-text units such as characters, lines and words. S-Expressions are a major win!

- Emacs' ability to specialize behavior based on major and minor modes.
- Ability to browse program code using tags, and getting fluent spoken feedback.
- Completion everywhere.
- Everything is searchable — this is a huge win when you cannot see the screen.
- Interactive spell-checking using ISpell with continuous spoken feedback augmented by aural highlights.
- Running code compilation and being able to jump to errors with spoken feedback.
- Ability to move through diff chunks when working with source code and source control systems; refined diffs as provided by the ediff package when speech-enabled is a major productivity win.
- Ability to easily move between email, document authoring and programming — though this may appear trivial, it continues to be one of Emacs' biggest wins.

Long-term Emacs users will recognize all of the above as being among the reasons why they do most things inside Emacs — there is little that is Emacspeak specific in the above list — except that Emacspeak was able to provide fluent, well-integrated contextual feedback for all of these tasks. And that was a game-changer given what I had had before Emacspeak. As a case in point, I did not dare program in Python before I speech-enabled Emacs' Python-Mode; the fact that white space is significant in Python made it difficult to program using a plain screen-reader that was unaware of the semantics of the underlying content being accessed.

### 5.1 Programming Defensively

As an aside, note that all of Emacspeak has been developed over the last 20 years with Emacspeak being the only adaptive technology on my system. This has led to some interesting design consequences, primary among them being a strong education in programming defensively. Here are some other key features of the Emacspeak code-base:

1. The code-base is extremely bushy rather than deeply hierarchical — this means that when a module breaks, it does not affect the rest of the system.
2. Separation of concerns with respect to the various layers, a tightly knit core speech library interfaces with any one of many speech servers running as an external process.
3. Audio formatting is abstracted by using the formalism defined in Aural CSS.
4. Emacspeak integrates with Emacs' user interface conventions by taking over a single prefix key C-e with all Emacspeak commands accessed through that single keymap. This helps embedding Emacspeak functionality into a large variety of third party modules without any loss of functionality.

## 6 Emacspeak And Authoring Documents

In 1994, my preferred environment for authoring all documents was LaTeX using the Auctex package. Later I started writing either LaTeX or HTML using the appropriate support modes; today I use org-mode to do most of my content authoring. Personally, I have never been a fan of What You See Is What You Get (WYSIWYG) authoring tools — in my experience that places an undue burden on the author by drawing attention away from the content to focus on the final appearance. An added benefit of creating content in Emacs in the form of light-weight markup is that the content is long-lived — I can still usefully process and re-use things I have written 25 years ago.

Emacs, with Emacspeak providing audio formatting and context-specific feedback remains my environment of choice for writing all forms of content ranging from simple email messages to polished documents for print publishing. And it is worth repeating that I never need to focus on what the content is going to look like — that job is best left to the computer.

As an example of producing high-fidelity visual content, see this write-up on Polyhedral Geometry that I published in 2000; all of the content, including the drawings were created by me using Emacs.

## 7 Emacspeak And The Early Days Of The Web

Right around the time that I was writing version 0.01 of emacspeak, a far more significant software movement was under way — the World Wide Web was moving from the realms of academia to the mainstream world with the launch of NCSA Mosaic — and in late 1994 by the first commercial Web browser in Netscape Navigator. Emacs had always enabled integrated access to FTP archives via package ange-ftp; in late 1993, William Perry released Emacs-W3, a Web browser for Emacs written entirely in Emacs Lisp. W3 was one of the first large packages to be speech-enabled by Emacspeak — later it was the browser on which I implemented the first draft of the Aural CSS specification. Emacs-W3 enabled many early innovations in the context of providing non-visual access to Web content, including audio formatting and structured content navigation; in summer of 1995, Dave Raggett and I outlined a few extensions to HTML Forms, including the label element as a means of associating metadata with interactive form controls in HTML, and many of these ideas were prototyped in Emacs-W3 at the time. Over the years, Emacs-W3 fell behind the times — especially as the Web moved away from cleanly structured HTML to a massive soup of unmatched tags. This made parsing and error-correcting badly-formed HTML markup expensive to do in Emacs-Lisp — and performance suffered. To add to this, mainstream users moved away because Emacs' rendering engine at the time was not rich enough to provide the type of visual renderings that users had come to expect. The advent of DHTML, and JavaScript based Web Applications finally killed off Emacs-W3 as far as most Emacs users were concerned.

But Emacs-W3 went through a revival on the emacspeak audio desktop in late 1999 with the arrival of XSLT, and Daniel Veillard's excellent implementation via the libxml2 and libxslt packages. With these in hand, Emacspeak was able to hand-off the bulk of HTML error correction to the xsltproc tool. The lack of visual fidelity didn't matter much for an eyes-free environment; so Emacs-W3 continued to be a useful tool for consuming large amounts of Web content that did not require JavaScript support.

During the last 24 months, libxml2 has been built into Emacs; this means that you can now parse arbitrary HTML as found in the wild without incurring a performance hit. This functionality was leveraged first by package shr (Simple HTML Renderer) within the gnus package for rendering HTML email. Later, the author of gnus and shr created a new light-weight HTML viewer called eww that is now part of Emacs 24. With improved support for variable pitch fonts and image embedding, Emacs is once again able to provide visual renderings for a large proportion of text-heavy Web content where it becomes useful for mainstream Emacs users to view at least some Web content within Emacs; during the last year, I have added support within emacspeak to extend package eww with support for DOM filtering and quick content navigation.

## 8 Audio Formatting — Generalizing Aural CSS

A key idea in Audio System For Technical Readings (AsTeR) was the use of various voice properties in combination with non-speech auditory icons to create rich aural renderings. When I implemented Emacspeak, I brought over the notion of audio formatting to all buffers in Emacs by creating a voice-lock module that paralleled Emacs' font-lock module. The visual medium is far richer in terms of available fonts and colors as compared to voice parameters available on TTS engines — consequently, it did not make sense to directly map Emacs' face properties to voice parameters. To aid in projecting visual formatting onto auditory space, I created property personality analogous to Emacs' face property that could be applied to content displayed in Emacs; module voice-lock applied that property appropriately, and the Emacspeak core handled the details of mapping personality values to the underlying TTS engine.

The values used in property personality were abstract, i.e., they were independent of any given speech engine. Later in the fall of 1995, I re-expressed these set of abstract voice properties in terms of Aural CSS; the work was published as a first draft toward the end of 1995, and implemented in Emacs-W3 in early 1996. Aural CSS was an appendix in the CSS-1.0 specification; later, it graduated to being its own module within CSS-2.0.

Later in 1996, all of Emacs' voice-lock functionality was re-implemented in terms of Aural CSS; the implementation has stood the test of time in that as I added support for more TTS engines, I was able to implement engine-specific mappings of Aural-CSS values. This meant that the rest of Emacspeak could define various types of voices for use in specific contexts without having to worry about individual TTS engines. Conceptually, property personality can be thought of as holding an aural display list — various parts of the system can annotate pieces of text with relevant properties that finally get rendered in the aggregate. This model also works well with the notion of Emacs overlays where a moving overlay is used to temporarily highlight text that has other context-specific properties applied to it.

Audio formatting as implemented in Emacspeak is extremely effective when working with all types of content ranging from richly structured mark-up documents (LaTeX, org-mode) and formatted Web pages to program source code. Perceptually, switching to audio formatted output feels like switching from a black-and-white monitor to a rich color display. Today, Emacspeak's audio formatted output is the only way I can correctly write else if vs elsif in various programming languages!

## 9 Conversational Gestures For The Audio Desktop

By 1996, Emacspeak was the only piece of adaptive technology I used; in fall of 1995, I had moved to Adobe Systems from DEC Research to focus on enhancing the Portable Document Format (PDF) to make PDF content repurposable. Between 1996 and 1998, I was primarily focused on electronic document formats — I took this opportunity to step back and evaluate what I had built as an auditory interface within Emacspeak. This retrospect proved extremely useful in gaining a sense of perspective and led to formalizing the high-level concept of Conversational Gestures and structured browsing/searching as a means of thinking about user interfaces.

By now, Emacspeak was a complete environment — I formalized what it provided under the moniker Complete Audio Desktop. The fully integrated user experience allowed me to move forward with respect to defining interaction models that were highly optimized to eyes-free interaction — as an example, see how Emacspeak interfaces with modes like dired (Directory Editor) forbrowsing and manipulating the filesystem, or proced (Process Editor) for browsing and manipulating running processes. Emacs' integration with ispell for spell checking, as well as its various completion facilities ranging from minibuffer completion to other forms of dynamic completion while typing text provided more opportunities for creating innovative forms of eyes-free interaction. With respect to what had gone before (and is still par for the course as far as traditional screen-readers are concerned), these types of highly dynamic interfaces present a challenge. For example, consider handling a completion interface using a screen-reader that is speaking the visual display. There is a significant challenge in deciding what to speak e.g., when presented with a list of completions, the currently typed text, and the default completion, which of these should you speak, and in what order? The problem gets harder when you consider that the underlying semantics of these items is generally not available from examining the visual presentation in a consistent manner. By having direct access to the underlying information being presented, Emacspeak had a leg up with respect to addressing the higher-level question — when you do have access to this information, how do you present it effectively in an eyes-free environment? For this and many other cases of dynamic interaction, a combination of audio formatting, auditory icons, and the ability to synthesize succinct messages from a combination of information items — rather than having to forcibly speak each item as it is rendered visually provided for highly efficient eyes-free interaction.

This was also when I stepped back to build out Emacspeak's table browsing facilities — see the online Emacspeak documentation for details on Emacspeak's table browsing functionality which continues to remain one of the richest collection of end-user affordances for working with two-dimensional data.

### 9.1 Speech-Enabling Interactive Games

So in 1997, I went the next step in asking — given access to the underlying infromation, is it possible to build effective eyes-free interaction to highly interactive tasks? I picked Tetris as a means of exploring this space, the result was an Emacspeak extension to speech-enable module tetris.el. The details of what was learned were published as a paper in Assets 98, and expanded as a chapter on Conversational Gestures in my book on Auditory Interfaces; that book was in a sense a culmination of stepping back and gaining a sense of perspective of what I had build during this period. The work on Conversational Gestures also helped in formalizing the abstract user interface layer that formed part of the XForms work at the W3C.

Speech-enabling games for effective eyes-free interaction has proven highly educational. Interactive games are typically built to challenge the user, and if the eyes-free interface is inefficient, you just wont play the game — contrast this with a task that you must perform, where you're likely to make do with a sub-optimal interface. Over the years, Emacspeak has come to include eyes-free interfaces to several games including Tetris, Sudoku, and of late the popular 2048 game. Each of these have in turn contributed to enhancing the interaction model in Emacspeak, and those innovations typically make their way to the rest of the environment.

## 10 Accessing Media Streams

Streaming real-time audio on the Internet became a reality with the advent of RealAudio in 1995; soon there were a large number of media streams available on the Internet ranging from music streams to live radio stations. But there was an interesting twist — for the most part, all of these media streams expected one to look at the screen, even though the primary content was purely audio (streaming video hadn't arrived yet!). Starting in 1996, Emacspeak started including a variety of eyes-free front-ends for accessing media streams. Initially, this was achieved by building a wrapper around trplayer — a headless version of RealPlayer; later I built Emacspeak module emacspeak-m-player for interfacing with package mplayer. A key aspect of streaming media integration in emacspeak is that one can launch and control streams without ever switching away from one's primary task; thus, you can continue to type email or edit code while seamlessly launching and controlling media streams. Over the years, Emacspeak has come to integrate with Emacs packages like emms as well as providing wrappers for mplayer and alsaplayer — collectively, these let you efficiently launch all types of media streams, including streaming video, without having to explicitly switch context.

In the mid-90's, Emacspeak started including a directory of media links to some of the more popular radio stations — primarily as a means of helping users getting started — Emacs' ability to rapidly complete directory and file-names turned out to be the most effective means of quickly launching everything from streaming radio stations to audio books. And even better — as the Emacs community develops better and smarter ways of navigating the filesystem using completions, e.g., package ido, these types of actions become even more efficient!

## 11 EBooks— Ubiquitous Access To Books

AsTeR — was motivated by the increasing availability of technical material as online electronic documents. While AsTeR processed the TeX family of markup languages, more general ebooks came in a wide range of formats, ranging from plain text generated from various underlying file formats to structured EBooks, with Project Gutenberg leading the way. During the mid-90's, I had access to a wide range of electronic materials from sources such as O'Reilly Publishing and various electronic journals — The Perl Journal (TPJ) is one that I still remember fondly.

Emacspeak provided fairly light-weight but efficient access to all of the electronic books I had on my local disk — Emacs' strengths with respect to browsing textual documents meant that I needed to build little that was specific to Emacspeak. The late 90's saw the arival of Daisy as an XML-based format for accessible electronic books. The last decade has seen the rapid convergence to epub as a distribution format of choice for electronic books. Emacspeak provides interaction modes that make organizing, searching and reading these materials on the Emacspeak Audio Desktop a pleasant experience. Emacspeak also provides an OCR-Mode — this enables one to call out to an external OCR program and read the content efficiently.

The somewhat informal process used by publishers like O'Reilly to make technical material available to users with print impairments was later formalized by BookShare — today, qualified users can obtain a large number of books and periodicals initially as Daisy-3 and increasingly as EPub. BookShare provides a RESTful API for searching and downloading books; Emacspeak module emacspeak-bookshare implements this API to create a client for browsing the BookShare library, downloading and organizing books locally, and an integrated ebook reading mode to round off the experience.

A useful complement to this suite of tools is the Calibre package for organizing ones ebook collection; Emacspeak now implements an EPub Interaction mode that leverages Calibre (actually sqlite3) to search and browse books, along with an integrated EPub mode for reading books.

## 12 Leveraging Computational Tools — From SQL And R To IPython Notebooks

The ability to invoke external processes and interface with them via a simple read-eval-loop (REPL) is perhaps one of Emacs' strongest extension points. This means that a wide variety of computational tools become immediately available for embedding within the Emacs environment — a facility that has been widely exploited by the Emacs community. Over the years, Emacspeak has leveraged many of these facilities to provide a well-integrated auditory interface.

Starting from a tight code, eval, test form of iterative programming as encouraged by Lisp. Applied to languages like Python and Ruby to explorative computational tools such as R for data analysis and SQL for database interaction, the Emacspeak Audio Desktop has come to encompass a collection of rich computational tools that provide an efficient eyes-free experience.

In this context, module ein — Emacs IPython Notebooks — provides another excellent example of an Emacs tool that helps interface seamlessly with others in the technical domain. IPython Notebooks provide an easy means of reaching a large audience when publishing technical material with interactive computational content; module ein brings the power and convenience of Emacs ' editting facilities when developing the content. Speech-enabling package ein is a major win since editting program source code in an eyes-free environment is far smoother in Emacs than in a browser-based editor.

## 13 Social Web — EMail, Instant Messaging, Blogging And Tweeting Using Open Protocols

The ability to process large amounts of email and electronic news has always been a feature of Emacs. I started using package vm for email in 1990, along with gnus for Usenet access many years before developing Emacspeak. So these were the first major packages that Emacspeak speech-enabled. Being able to access the underlying data structures used to visually render email messages and Usenet articles enabled Emacspeak to produce rich, succinct auditory output — this vastly increased my ability to consume and organize large amounts of information. Toward the turn of the century, instant messaging arrived in the mainstream — package tnt provided an Emacs implementation of a chat client that could communicate with users on the then popular AOL Instant Messenger platform. At the time, I worked at IBM Research, and inspired by package tnt, I created an Emacs client called ChatterBox using the Lotus Sametime API — this enabled me to communicate with colleagues at work from the comfort of Emacs. Packages like vm, gnus, tnt and ChatterBox provide an interesting example of how availability of a clean underlying API to a specific service or content stream can encourage the creation of efficient (and different) user interfaces. The touchstone of such successful implementations is a simple test — can the user of a specific interface tell if the person whom he is communicating with is also using the same interface? In each of the examples enumerated above, a user at one end of the communication chain cannot tell, and in fact shouldn't be able to tell what client the user at the other end is using. Contrast this with closed services that have an inherent lock-in model e.g., proprietary word processors that use undocumented serialization formats — for a fun read, see this write-up on Universe Of Fancy Colored Paper.

Today, my personal choice for instant messaging is the open Jabber platform. I connect to Jabber via Emacs package emacs-jabber and with Emacspeak providing a light-weight wrapper for generating the eyes-free interface, I can communicate seamlessly with colleagues and friends around the world.

As the Web evolved to encompass ever-increasing swathes of communication functionality that had already been available on the Internet, we saw the world move from Usenet groups to Blogs — I remember initially dismissing the blogging phenomenon as just a re-invention of Usenet in the early days. However, mainstream users flocked to Blogging, and I later realized that blogging as a publishing platform brought along interesting features that made communicating and publishing information much easier. In 2005, I joined Google; during the winter holidays that year, I implemented a light-weight client for Blogger that became the start of Emacs package g-client — this package provides Emacs wrappers for Google services that provide a RESTful API.

## 14 The RESTful Web — Web Wizards And URL Templates For Faster Access

Today, the Web, based on URLs and HTTP-style protocols is widely recognized as a platform in its own right. This platform emerged over time — to me, Web APIs arrived in the late 90's when I observed the following with respect to my own behavior on many popular sites:

1. I opened a Web page that took a while to load (remember, I was still using Emacs-W3),
2. I then searched through the page to find a form-field that I filled out, e.g., start and end destinations on Yahoo Maps,
3. I hit submit, and once again waited for a heavy-weight HTML page to load,
4. And finally, I hunted through the rendered content to find what I was looking for.

This pattern repeated across a wide-range of interactive Web sites ranging from AltaVista for search (this was pre-Google), Yahoo Maps for directions, and Amazon for product searches to name but a few. So I decided to automate away the pain by creating Emacspeak module emacspeak-websearch that did the following:

1. Prompt via the minibuffer for the requisite fields,
2. Consed up an HTTP GET URL,
3. Retrieved this URL,
4. And filtered out the specific portion of the HTML DOM that held the generated response.

Notice that the above implementation hard-wires the CGI parameter names used by a given Web application into the code implemented in module emacspeak-websearch. REST as a design pattern had not yet been recognized, leave alone formalized, and module emacspeak-websearch was initially decryed as being fragile.

However, over time, the CGI parameter names remained fixed — the only things that have required updating in the Emacspeak code-base are the content filtering rules that extract the response — for popular services, this has averaged about one to two times a year.

I later codified these filtering rules in terms of XPath, and also integrated XSLT-based pre-processing of incoming HTML content before it got handed off to Emacs-W3 — and yes, Emacs/Advice once again came in handy with respect to injecting XSLT pre-processing into Emacs-W3!

Later, in early 2000, I created companion module emacspeak-url-templates — partially inspired by Emacs' webjump module. URL templates in Emacspeak leveraged the recognized REST interaction pattern to provide a large collection of Web widgets that could be quickly invoked to provide rapid access to the right pieces of information on the Web.

The final icing on the cake was the arrival of RSS and Atom feeds and the consequent deep-linking into content-rich sites — this meant that Emacspeak could provide audio renderings of useful content without having to deal with complex visual navigation! While Google Reader existed, Emacspeak provided a light-weight greader client for managing ones feed subscriptions; with the demise of Google Reader, I implemented module emacspeak-feeds for organizing feeds on the Emacspeak desktop. A companion package emacspeak-webspace implements additional goodies including a continuously updating ticker of headlines taken from the user's collection of subscribed feeds.

## 15 Mashing It Up — Leveraging Evolving Web APIs

The next step in this evolution came with the arrival of richer Web APIs — especially ones that defined a clean client/server separation. In this respect, the world of Web APIs is a somewhat mixed bag in that many Web sites equate a Web API with a JS-based API that can be exclusively invoked from within a Web-Browser run-time. The issue with that type of API binding is that the only runtime that is supported is a full-blown Web browser; but the arrival of native mobile apps has actually proven a net positive in encouraging sites to create a cleaner separation. Emacspeak has leveraged these APIs to create Emacspeak front-ends to many useful services, here are a few:

1. Minibuffer completion for Google Search using Google Suggest to provide completions.
2. Librivox for browsing and playing free audio books.
3. NPR for browsing and playing NPR archived programs.
4. BBC for playing a wide variety of streaming content available from the BBC.
5. A Google Maps front-end that provides instantaneous access to directions and Places search.
6. Access to Twitter via package twittering-mode.

And a lot more than will fit this margin! This is an example of generalizing the concept of a mashup as seen on the Web with respect to creating hybrid applications by bringing together a collection of different Web APIs. Another way to think of such separation is to view an application as a head and a body — where the head is a specific user interface, with the body implementing the application logic. A cleanly defined separation between the head and body allows one to attach different user interfaces i.e., heads to the given body without any loss of functionality, or the need to re-implement the entire application. Modern platforms like Android enable such separation via an Intent mechanism. The Web platform as originally defined around URLs is actually well-suited to this type of separation — though the full potential of this design pattern remains to be fully realized given today's tight association of the Web to the Web Browser.

## 16 Conclusion

In 1996, I wrote an article entitled User Interface — A Means To An End pointing out that the size and shape of computers were determined by the keyboard and display. This is even more true in today's world of tablets, phablets and large-sized phones — with the only difference that the keyboard has been replaced by a touch screen. The next generation in the evolution of personal devices is that they will become truly personal by being wearables — this once again forces a separation of the user interface peripherals from the underlying compute engine. Imagine a variety of wearables that collectively connect to ones cell phone, which itself connects to the cloud for all its computational and information needs. Such an environment is rich in possibilities for creating a wide variety of user experiences to a single underlying body of information; Eyes-Free interfaces as pioneered by systems like Emacspeak will come to play an increasingly vital role alongside visual interaction when this comes to pass.

## Emacspeak And Company: Complete Anything Front-End For emacspeak

## 1 Emacspeak And Company: Complete Anything Front-End For Emacspeak

Module emacspeak-company speech-enables package Company — a flexible complete-anything extension for Emacs. Package company gains much of its flexibility by providing an extensible framework for both back-ends and front-ends; back-ends are responsible for language-specific support e.g., C++ vs Emacs Lisp; front-ends can provide different visualizations of the available completions.

I started using package company as I taught myself to program in Go over the last couple of weeks, and package emacspeak-company was one of the bi-products.

### 1.1 Using Company With Emacspeak

You can turn on company-mode in dividual buffers; you can also turn it on globally. Company comes pre-packaged with backend support for many programming languages; for programming in Go, I use module company-go in conjunction with the GoCode tool.

See customization group company to customize package company; Emacspeak loads package emacspeak-company when packagecompany is loaded, and that automatically sets up the Emacspeak front-end.

Once activated, package company shows available completions where available once you type a prescribed number of characters. Available candidates are displayed visually via an overlay and can be traversed using either the up/down arrows or keys M-n and M-p. You can also search and filter the available completions, see documentation for command company-mode. The available visual front-ends also display relevant metadata for the current candidate in the echo area.

Front-end emacspeak-company performs the following additional actions:

- Speaks current candidate along with the relevant metadata.
- The metadata is spoken using voice-annotate.
- Auditory icon help indicates that completion has started.
- pressing F1 during completion displays documentation for the current candidate.
- You can choose the current candidate by pressing RET; this

speaks the selected candidate.

- Auditory icon close-object indicates that completion has finished.

### 1.2 Insights From Speech-Enabling Company

Company uses a fluid visual interface to display completions without the user having to switch contexts — it achieves this by using overlays that appear briefly in the form of a conceptual tooltip. These pseudo tooltips are created and destroyed via a timer; keyboard interaction causes these to be updated — including hiding the tooltip where appropriate.

Module emacspeak-company speech-enables this interface by examining the underlying information used to create the visualization to produce an effective audio-formatted representation. The net effect is that you can write code with completion helping you along the way; you do not need to switch tasks to lookup details as to what completions are available.

### 1.3 Acknowledgements

Thanks again to the authors of package company for a really nice tool — it's a real productivity winner — especially when learning a new language and its built-in packages.

I found these articles really helpful while learning to write package emacspeak-company.

- Setting Up GoMode
- Writing Go In Emacs

Learning Go was a pleasure (it's still a pleasure — I'm still learning:-)) and the documentation on GoLang is excellent. As an added bonus, that entire site uses clean, well-formed HTML without any unnecessary artifacts that make so much of today's Web a giant mess; I have been able to use Emacs/EWW exclusively while working with golang.org — a real bonus for someone programming heavily in Emacs.

## Announcing Emacspeak 40.0 AKA WowDog!

# Emacspeak 40.0—WowDog—Unleashed!

## 1 Emacspeak-40.0 (WowDog) Unleashed!

** For Immediate Release:

San Jose, Calif., (May 13, 2014) Emacspeak: Redefining Accessibility In The Era Of Web Computing –Zero cost of upgrades/downgrades makes priceless software affordable!

Emacspeak Inc (NASDOG: ESPK) --http://emacspeak.sf.net– announces the immediate world-wide availability of Emacspeak 40.0 (WowDog) –a powerful audio desktop for leveraging today's evolving data, social and service-oriented Web cloud.

### 1.1 Investors Note:

With several prominent tweeters expanding coverage of #emacspeak, NASDOG: ESPK has now been consistently trading over the social net at levels close to that once attained by DogCom high-fliers—and as of November 2013 is trading at levels close to that achieved by once better known stocks in the tech sector.

### 1.2 What Is It?

Emacspeak is a fully functional audio desktop that provides complete eyes-free access to all major 32 and 64 bit operating environments. By seamlessly blending live access to all aspects of the Internet such as Web-surfing, blogging, social computing and electronic messaging into the audio desktop, Emacspeak enables speech access to local and remote information with a consistent and well-integrated user interface. A rich suite of task-oriented tools provides efficient speech-enabled access to the evolving service-oriented social Web cloud.

### 1.3 Major Enhancements:

- Emacs EWW: Consume Web content efficiently. 📚
- emacspeak-url-templates: Smart Web access. ♅
- emacspeak-websearch.el Find things fast. ♁
- gmaps.el: Find places, read reviews, get there. 🌐
- Feed Browser Consume feeds post Google-Reader. ␌
- Freebase Search: Explore freebase knowledge base. 🆓
- Emacs 24.4: Supports all new features in Emacs 24.4. 🌚
- And a lot more than wil fit this margin. …

### 1.4 Establishing Liberty, Equality And Freedom:

Never a toy system, Emacspeak is voluntarily bundled with all major Linux distributions. Though designed to be modular, distributors have freely chosen to bundle the fully integrated system without any undue pressure—a documented success for the integrated innovation embodied by Emacspeak. As the system evolves, both upgrades and downgrades continue to be available at the same zero-cost to all users. The integrity of the Emacspeak codebase is ensured by the reliable and secure Linux platform used to develop and distribute the software.

Extensive studies have shown that thanks to these features, users consider Emacspeak to be absolutely priceless. Thanks to this wide-spread user demand, the present version remains priceless as ever—it is being made available at the same zero-cost as previous releases.

At the same time, Emacspeak continues to innovate in the area of eyes-free social interaction and carries forward the well-established Open Source tradition of introducing user interface features that eventually show up in luser environments.

On this theme, when once challenged by a proponent of a crash-prone but well-marketed mousetrap with the assertion "Emacs is a system from the 70's", the creator of Emacspeak evinced surprise at the unusual candor manifest in the assertion that it would take popular idiot-proven interfaces until the year 2070 to catch up to where the Emacspeak audio desktop is today. Industry experts welcomed this refreshing breath of Courage Certainty and Clarity (CCC) at a time when users are reeling from the Fear Uncertainty and Doubt (FUD) unleashed by complex software systems backed by even more convoluted press releases.

### 1.5 Independent Test Results:

Independent test results have proven that unlike some modern (and not so modern) software, Emacspeak can be safely uninstalled without adversely affecting the continued performance of the computer. These same tests also revealed that once uninstalled, the user stopped functioning altogether. Speaking with Aster Labrador, the creator of Emacspeak once pointed out that these results re-emphasize the user-centric design of Emacspeak; "It is the user –and not the computer– that stops functioning when Emacspeak is uninstalled!".

#### 1.5.1 Note from Aster,Bubbles and Tilden:

UnDoctored Videos Inc. is looking for volunteers to star in a video demonstrating such complete user failure.

### 1.6 Obtaining Emacspeak:

Emacspeak can be downloaded from Google Code –see http://code.google.com/p/emacspeak/ You can visit Emacspeak on the WWW at http://emacspeak.sf.net. You can subscribe to the emacspeak mailing list emacspeak@cs.vassar.edu by sending mail to the list request address emacspeak-request@cs.vassar.edu.

Emacspeak-8.0 –(AKA Emacspeak-98++) code named BlackDog– was a major upgrade to the speech output extension to Emacs.

Emacspeak-95 (code named Illinois) was released as OpenSource on the Internet in May 1995 as the first complete speech interface to UNIX workstations. The subsequent release, Emacspeak-96 (code named Egypt) made available in May 1996 provided significant enhancements to the interface. Emacspeak-97 (Tennessee) went further in providing a true audio desktop. Emacspeak-98 integrated Internetworking into all aspects of the audio desktop to provide the first fully interactive speech-enabled WebTop.

## Emacspeak: EWW Updates For The Complete Audio Desktop

# Emacspeak EWW Updates

## 1 Emacspeak EWW Updates

Within a few weeks, EWW has become my prefered way of consuming large amounts of Web content — except for simple fill-out forms, it has entirely replaced Emacs/W3 for me. Goes without saying that I still use ChromeVox for Js-heavy Web sites.

This article summarizes some of the major enhancements to EWW implemented in module emacspeak-eww; See the online documentation and key-binding help for complete details.

### 1.1 EWW And Masquerade Mode

You can now have EWW masquerade as modern browsers; note that some sites might serve you more feature-rich content in this mode.

### 1.2 Smart Google Searches

All of the features from module emacspeak-google have been integrated to work with EWW. In addition, if running in masquerade-mode, you can quickly access knowledge cards if available on the current results page.

### 1.3 Rich DOM Filtering

The suite of DOM filtered views has been enhanced to support filtering by class, id, role, or element-list. In addition, you can also invert these filters.

### 1.4 Structure Navigation

Emacspeak now supports structured navigation in pages rendered by EWW, see the key-bindings for details.

### 1.5 Integration With URL-Templates And Feeds

EWW is now fully integrated with Emacspeak WebSearch, URL-Templates and Feeds. This means that hitting g in an EWW buffer does the right thing with respect to updating the rendered buffer:

- If viewing a feed, the feed is reloaded before it is rendered as HTML.
- If viewing a url-template, the template is re-opened, prompting for user-input if needed.

### 1.6 XSLT Integration

Most of the functionality provided by module emacspeak-xslt for filtering the DOM in the world of Emacs/W3 is achieved more effectively via the DOM filtering commands in emacspeak-eww —that said, XSLT pre-processing is fully integrated with EWW via supporting modules emacspeak-ew and emacspeak-webutils.

### 1.7 Other Fun Things To Do

Here are some more fun things that might be worth doing:

- Integrate PhantomJS with EWW to load content that is rendered via JS document.write.
- Integrate with CasperJS to enable interaction with light-weight WebApps.
- Integrate with Chrome over the debugger API to access the live DOM within Chrome.

Share And Enjoy

## Emacspeak Webspace: Glancing At Information On The Audio Desktop

# A Web News Ticker For Emacs

## 1 WebSpace: A Web News Ticker For Emacs

Module Emacspeak-Webspace provides a rolling ticker of information that is automatically retrieved, cached and maintained by Emacspeak. Using this functionality, you can set up specific buffers to have interesting tidbits of information displayed automatically in the header-line; Emacspeak speaks these items of information as you switch contexts. This article explains the usage model and underlying design of Emacspeak Webspaces.

### 1.1 Background

The Emacspeak Webspace module was originally created in early Interaction Free Information Access (2008) because I wanted the audio equivalent of being able to quickly glance at information. Here are some aspects of visual interaction that I wanted to emulate:

- You can quickly glance at something while switching contexts, and ignore it if it is not important.
- The object that you glance at while switching contexts does not become an object of attention ie, the casual task remains casual, as opposed to becoming the primary task. Email is the antithesis to this model — where if you start glancing at email, it's a sufficiently strong distraction that you'll start doing email — as opposed to what you were supposed to be doing.
- If the item you glanced at deserves further attention, you can come back to it later — and the system gives you sufficient confidence in your ability to come back to it later — note that this is essential to ensure the previous requirement.
- Items are cached but get pushed out by newer items — this makes sure you dont feel pressured to read everything or have to explicitly catch-up — in prior systems including email and Google Reader, I always found the task of hitting catch-up without reading everything a fairly stressful experience.
- Applied to information updates, think hallway conversations outside your office — you mostly ignore them, but sometime get drawn because you hear some specific keywords and/or concepts that draw your attention.

### 1.2 Early Implementation In 2009

I used the WebSpace functionality in Emacspeak for news and weather updates starting 2009; at some time in late 2009, I cut it over to get updates from my Google Reader stream. It was extremely effective for my usage pattern — I typically activated the functionality in all shell buffers. In my work style where I switch among the primary tasks of engineering (writing/reviewing code), writing/reviewing design documents, and doing email to facilitate the previous two tasks, the shell buffer is where I switch to while context-switching e.g., launching a build after writing code as an example. Having the Webspace functionality say something interesting at those times was optimal.

### 1.3 Initial Implementation And Design

The information to be pulled in the rolling header line is pulled from a cache — in 2009, this cache was populated from my Google Reader stream. The cache was maintained in a ring with older items falling off the end. You could optionally switch to a buffer displaying all of the currently cached items — this functionality assured me that I could always later find an item that had caught my attention while I was in the process of context switching amongst tasks. Notice that if I didn't go back and check for that item within a day, it would fall off the ring-buffer cache — and this usually would mean that it likely wasn't that important after all.

### 1.4 Life After Google Reader

With the passing of Google Reader last year, I started implementing the feed-reading functionality I needed in Emacspeak independent of Google Reader; see the earlier article in this blog titled Managing And Accessing Feeds On The Emacspeak Audio Desktop. Next, I updated the Emacspeak WebSpace functionality to build its cache from the set of feeds in emacspeakfeeds.

### 1.5 Usage Pattern

This section details my own usage pattern and set-up — this is by no means the only way to use this functionality.

1. Emacspeak binds Webspace functionality to Hyper Space as a prefix key.
2. Hyper Space h invokes command emacspeak-webspace-headlines — this command initializes the feed-store cache, and sets up the header-line in the current buffer to display a rolling ticker. Note that you can invoke this command in multiple buffers; those buffers will share a common headlines cache.
3. The feed-store is updated during Emacs idle-time; I often invoke the elisp form (emacspeak-webspace-headlines-populate) to populate the cache initially. Note that depending on your network, and the number of feeds you have in emacspeak-feeds, this can block emacs for a couple of minutes.
4. Command emacspeak-webspace-headlines-browse displays an interactive buffer containing the current set of cached headlines — this is where you go to track down a headline you heard in passing. I bind this to Super h by customizing emacspeak-super-keys.
5. You can set up other types of information in your rolling header — something I initially used it for was weather — see command emacspeak-webspace-weather personally, I 've not found this as useful in CA given how consistently good the weather is here.
6. For related work in Emacs, see Emacs package newsticker. That package works well with Emacspeak, but in using it earlier, I found that I could not prevent myself from starting to read content i.e., it failed to meet the glance and continue requirement.

## Searching GMail Using IMap And GNUS

## 1 Searching GMail Using IMap and GNUS

Emacs package GNUS provides a very efficient interface for consuming large amounts of email. You can access GMail using GNUS' IMap interface, for my own configuration for doing this, see file tvr/gnus-prepare.el in the Emacspeak SVN repository. Module gm-nnir.el in package g-client implements some convenience hooks to enable efficient searching of GMail. Module emacspeak-gnus has been updated to bind commands from module gm-nnir.el to ? and / in the Group buffer.

### 1.1 Basic Usage

Assuming you already have GNUS configured to read GMail via IMap, you can:

- Press / in the groups buffer to search your mail. This command accepts all GMail queries, so for example,

          after: 2014/02/01 to: me

Will find all messages received after February 1, 2014 and addressed to you.

          label: foo after: 2014/01/01

Will find messages with label foo and received after January 1, 2014.

- Press ? in the Group buffer to execute a more extensive search command; this accepts both IMap query specifications (per RFC 3501) as well as GMail query specifications. The command provides smart completion, follow the prompts to build up complex queries. In general, there is almost nothing you cannot do with the GMail query language, so this command is mostly there as a backup.

### 1.2 The Technical Details

The GMail query language is exposed to IMap via custom search key X-GM-RAW; commands gm-nnir-group-make-gmail-group and gm-nnir-group-make-nnir-group use this functionality to construct ephemeral groups that hold the search results.

## Exploring And Accessing BBC Podcasts and Program Archives

# Exploring BBC Podcasts And Program Archives

## 1 Exploring BBC Podcasts And Program Archives

### 1.1 Summary

A short overview of tools on the emacspeak desktop for easily exploring and accessing BBC program content.

### 1.2 Background

The BBC offers a wealth of audio content from both domestic BBC Radio as well as BBC World Service. Much of this content is available as Podcasts for a week after it has been broadcast; in some instances, content is archived and available for more than a week.

The primary gateway to this content is BBC IPlayer. In addition, one can subscribe to RSS feeds for BBC Podcasts.

### 1.3 Accessing BBC Content From Emacspeak

Here are some of the tools I use on the Emacspeak desktop to quickly find and access content from the BBC:

- The BBC publishes a continuously updated directory of RSS feeds; Emacspeak url template BBC Podcast Directory can be used to open this directory of feeds.
- With the above directory of feeds at hand, it is easy to subscribe to oft-accessed feeds via emacspeak-feeds — see Managing And Accessing Feeds.
- In addition to the directory of feeds covered above, the BBC publishes a detailed program guide as XML; Emacspeak url template BBC Program Guide accesses the program guide.
- The program guide described above gives access to RSS feeds for both current programs as

well as past archives. The program guide is a wealth of information that makes all the information available in one location, unlike the BBC IPlayer site.

- A note for UK users; the program guide above is presently set up to only show content that is available world-wide; if you're in the UK, you may want to remove the test for

          region='all'

in the XSL stylesheet emacspeak/xsl/bbc-ppg.xsl.

- You can find the XML feed for the BBC Program Guide, as well as the associated XML Schema definition on the BBC's Web site.
- Finally, you can access the BBC IPlayer page for any given BBC channel via Emacspeak url template BBC IPlayer.

Share And Enjoy! And Hear's Wishing Everyone A Very Happy 2014!

## Managing And Accessing Feeds On The Emacspeak Audio Desktop

## 1 Managing And Accessing Feeds On The Emacspeak Audio Desktop

### 1.1 Summary

Feature emacspeak-feeds enables rapid access to managing and accessing Atom, RSS and OPML feeds. Feeds can be browsed from a dedicated buffer, or accessed via minibuffer completion for oft-accessed feeds. Feeds are stored as a user customizable option, and can be added and deleted either via Emacs' customize interface or directly via interactive Emacs commands.

### 1.2 How It Works

The list of subscribed feeds is stored in variable emacspeak-feeds which is managed via Emacs' customize interface. Each entry this list contains a label for the feed, the feed URL, and the type of the feed (rss_, atom, or opml).

Interactive command emacspeak-webspace-feed-reader opens a buffer containing the list of subscribed feeds; feeds can be opened by pressing enter on the relevant feed.

Oft-accessed feeds can be opened directly via command emacspeak-feed-browse bound to C-e C-u — this command prompts for a feed label with minibuffer completion.

Feeds can be added or deleted by customizing emacspeak-feeds via Emacs' M-x customize-variable — bound by default in emacspeak to C-h V. Alternatively, interactive command emacspeak-feed-add-feed bound to C-e M-u can be used to subscribe to feeds. Note that both methods result in the subscribed feed being stored in emacspeak-feeds.

## Reading Web Content Efficiently

# reading-web-content.org

## 1 Reading Web Content

### 1.1 Background

I still find reading Web content in emacs to be way more efficient than in modern browsers like Chrome with ChromeVox enabled. Chrome+ChromeVox is what I use for rich Web Applications; but when it comes down to reading straight content ranging from technical documentation to news and current affairs, I find that I can read a lot more content in a fixed amount of time with Emacs+Emacspeak than I can with the Chrome+ChromeVox combination.

### 1.2 Welcome EWW: Emacs Web Wowser

The author of GNUS recently added package EWW (Emacs Web Wowser) to The Emacs repository — see his announcement. Emacspeak 37.0 included a small addition called shr-url that leveraged his earlier shr package; I've now added support for EWW in the Emacspeak source tree. Note that EWW is in the Emacs source tree, i.e. it will be part of Emacs 24.4, but you can use it now if you build your own version of Emacs, or obtain an Emacs that is build from the Emacs source repository.

EWW and SHR are interesting because they both leverage libxml2 to parse the incoming HTML. This is way faster than the native elisp browsing used in Emacs/W3. In my personal opinion, it also opens up more possibilities than Emacs/W3M with respect to manipulating and filtering content from elisp --- something that helps create a better reading experience when using Emacspeak.

### 1.3 EWW Tips And Tricks

I've mailed out a small patch to package eww that facilitates implementing such higher-level commands; for now, you can find that patch in emacspeak/lisp/patches in the Emacspeak svn repository. With that patch in place, you can do the following to efficiently filter popular news sites such as the New York Times (I use http://mobile.nytimes.com) or CNN (http://cnn.com).

When visiting these and other content-heavy sites, try:

A
  Filter by attributes,
E
  Filter by elements
R
  Restore original contents

To flexibly obtain multiple views of a Web site.

## Emacspeak 39.0 (BigDog) Unleashed!

# Emacspeak 39.0—BigDog—Unleashed!

## 1 Emacspeak-39.0 (BigDog) Unleashed!

** For Immediate Release:

San Jose, Calif., (November 27, 2013)
Emacspeak: Redefining Accessibility In The Era Of Social Cloud Computing
– Zero cost of upgrades/downgrades makes priceless software affordable!

Emacspeak Inc (NASDOG: ESPK) --http://emacspeak.sf.net-- announces the immediate world-wide availability of Emacspeak 39.0 (BigDog) – a powerful audio desktop for leveraging today's evolving data, social and service-oriented Web cloud.

### 1.1 Investors Note:

With several prominent tweeters expanding coverage of #emacspeak, NASDOG: ESPK has now been consistently trading over the social net at levels close to that once attained by DogCom high-fliers—and as of November 2013 is trading at levels close to that achieved by once better known stocks in the tech sector.

### 1.2 What Is It?

Emacspeak is a fully functional audio desktop that provides complete eyes-free access to all major 32 and 64 bit operating environments. By seamlessly blending live access to all aspects of the Internet such as Web-surfing, blogging, social computing and electronic messaging into the audio desktop, Emacspeak enables speech access to local and remote information with a consistent and well-integrated user interface. A rich suite of task-oriented tools provides efficient speech-enabled access to the evolving service-oriented social Web cloud.

### 1.3 Major Enhancements:

- Speech-Enables Ipython Notebook interaction via package EIN. 🐍
- Speech-enables Chrome/Firefox integration via package JSS. ⱒ
- Improved Chrome debugging via package Kite. ⾶
- Updated search wizards for rapid Web access. ♄
- Updated URL templates for instant Web access. ♅
- Improved Emacs 24.3 support. 🌑
- And a lot more than wil fit this margin. …

### 1.4 Establishing Liberty, Equality And Freedom:

Never a toy system, Emacspeak is voluntarily bundled with all major Linux distributions. Though designed to be modular, distributors have freely chosen to bundle the fully integrated system without any undue pressure—a documented success for the integrated innovation embodied by Emacspeak. As the system evolves, both upgrades and downgrades continue to be available at the same zero-cost to all users. The integrity of the Emacspeak codebase is ensured by the reliable and secure Linux platform used to develop and distribute the software.

Extensive studies have shown that thanks to these features, users consider Emacspeak to be absolutely priceless. Thanks to this wide-spread user demand, the present version remains priceless as ever—it is being made available at the same zero-cost as previous releases.

At the same time, Emacspeak continues to innovate in the area of eyes-free social interaction and carries forward the well-established Open Source tradition of introducing user interface features that eventually show up in luser environments.

On this theme, when once challenged by a proponent of a crash-prone but well-marketed mousetrap with the assertion "Emacs is a system from the 70's", the creator of Emacspeak evinced surprise at the unusual candor manifest in the assertion that it would take popular idiot-proven interfaces until the year 2070 to catch up to where the Emacspeak audio desktop is today. Industry experts welcomed this refreshing breath of Courage Certainty and Clarity (CCC) at a time when users are reeling from the Fear Uncertainty and Doubt (FUD) unleashed by complex software systems backed by even more convoluted press releases.

### 1.5 Independent Test Results:

Independent test results have proven that unlike some modern (and not so modern) software, Emacspeak can be safely uninstalled without adversely affecting the continued performance of the computer. These same tests also revealed that once uninstalled, the user stopped functioning altogether. Speaking with Aster Labrador, the creator of Emacspeak once pointed out that these results re-emphasize the user-centric design of Emacspeak; "It is the user – and not the computer – that stops functioning when Emacspeak is uninstalled!".

#### 1.5.1 Note from Aster,Bubbles and Tilden:

UnDoctored Videos Inc. is looking for volunteers to star in a video demonstrating such complete user failure.

### 1.6 Obtaining Emacspeak:

Emacspeak can be downloaded from Google Code Hosting – see http://code.google.com/p/emacspeak/ You can visit Emacspeak on the WWW at http://emacspeak.sf.net. You can subscribe to the emacspeak mailing list emacspeak@cs.vassar.edu by sending mail to the list request address emacspeak-request@cs.vassar.edu. The BigDog release is at http://emacspeak.googlecode.com/files/emacspeak-39.0.tar.bz2. The latest development snapshot of Emacspeak is always available via Subversion from Google Code at http://emacspeak.googlecode.com/svn/trunk/

### 1.7 History:

Emacspeak 39.0 continues the Emacspeak tradition of increasing the breadth of user tasks that are covered without introducing unnecessary bloatware. Emacspeak 38.0 is the latest in a series of award-winning releases from Emacspeak Inc. Emacspeak 37.0 continues the tradition of delivering robust software as reflected by its code-name. Emacspeak 36.0 enhances the audio desktop with many new tools including full EPub support — hence the name EPubDog. Emacspeak 35.0 is all about teaching a new dog old tricks — and is aptly code-named HeadDog in honor of our new Press/Analyst contact. emacspeak-34.0 (AKA Bubbles) established a new beach-head with respect to rapid task completion in an eyes-free environment.

Emacspeak 29.0—AKAAbleDog—is a testament to the resilliance and innovation embodied by Open Source software—it would not exist without the thriving Emacs community that continues to ensure that Emacs remains one of the premier user environments despite perhaps also being one of the oldest. Emacspeak 28.0—AKA PuppyDog—exemplifies the rapid pace of development evinced by Open Source software. Emacspeak 27.0—AKA FastDog—is the latest in a sequence of upgrades that make previous releases obsolete and downgrades unnecessary.

Emacspeak-15.0 – code named SmartDog – followed up on TopDog as the next in a continuing a series of award-winning audio desktop releases from Emacspeak Inc. Emacspeak-14.0 – code named TopDog – was the first release of this millennium. Emacspeak-13.0 – codenamed YellowLab – was the closing release of the 20th. century. Emacspeak-12.0 – code named GoldenDog – began leveraging the evolving semantic WWW to provide task-oriented speech access to Webformation. Emacspeak-11.0 – code named Aster – went the final step in making Linux a zero-cost Internet access solution for blind and visually impaired users. Emacspeak-10.0 – (AKA Emacspeak-2000) code named WonderDog – continued the tradition of award-winning software releases designed to make eyes-free computing a productive and pleasurable experience. Emacspeak-9.0 – (AKA Emacspeak 99) code named BlackLab – continued to innovate in the areas of speech interaction and interactive accessibility. Emacspeak-8.0 – (AKA Emacspeak-98++) code named BlackDog – was a major upgrade to the speech output extension to Emacs.

Emacspeak-95 (code named Illinois) was released as OpenSource on the Internet in May 1995 as the first complete speech interface to UNIX workstations. The subsequent release, Emacspeak-96 (code named Egypt) made available in May 1996 provided significant enhancements to the interface. Emacspeak-97 (Tennessee) went further in providing a true audio desktop. Emacspeak-98 integrated Internetworking into all aspects of the audio desktop to provide the first fully interactive speech-enabled WebTop.

### 1.4 Establishing Liberty, Equality And Freedom:

Never a toy system, Emacspeak is voluntarily bundled with all major Linux distributions. Though designed to be modular, distributors have freely chosen to bundle the fully integrated system without any undue pressure—a documented success for the integrated innovation embodied by Emacspeak. As the system evolves, both upgrades and downgrades continue to be available at the same zero-cost to all users. The integrity of the Emacspeak codebase is ensured by the reliable and secure Linux platform used to develop and distribute the software.

Extensive studies have shown that thanks to these features, users consider Emacspeak to be absolutely priceless. Thanks to this wide-spread user demand, the present version remains priceless as ever—it is being made available at the same zero-cost as previous releases.

At the same time, Emacspeak continues to innovate in the area of eyes-free social interaction and carries forward the well-established Open Source tradition of introducing user interface features that eventually show up in luser environments.

On this theme, when once challenged by a proponent of a crash-prone but well-marketed mousetrap with the assertion "Emacs is a system from the 70's", the creator of Emacspeak evinced surprise at the unusual candor manifest in the assertion that it would take popular idiot-proven interfaces until the year 2070 to catch up to where the Emacspeak audio desktop is today. Industry experts welcomed this refreshing breath of Courage Certainty and Clarity (CCC) at a time when users are reeling from the Fear Uncertainty and Doubt (FUD) unleashed by complex software systems backed by even more convoluted press releases.

### 1.5 Independent Test Results:

Independent test results have proven that unlike some modern (and not so modern) software, Emacspeak can be safely uninstalled without adversely affecting the continued performance of the computer. These same tests also revealed that once uninstalled, the user stopped functioning altogether. Speaking with Aster Labrador, the creator of Emacspeak once pointed out that these results re-emphasize the user-centric design of Emacspeak; "It is the user –and not the computer– that stops functioning when Emacspeak is uninstalled!".

#### 1.5.1 Note from Aster,Bubbles and Tilden:

UnDoctored Videos Inc. is looking for volunteers to star in a video demonstrating such complete user failure.

### 1.6 Obtaining Emacspeak:

Emacspeak can be downloaded from Google Code Hosting –see http://code.google.com/p/emacspeak/ You can visit Emacspeak on the WWW at http://emacspeak.sf.net. You can subscribe to the emacspeak mailing list emacspeak@cs.vassar.edu by sending mail to the list request address emacspeak-request@cs.vassar.edu.

### 1.7 History:

Emacspeak 38.0 is the latest in a series of award-winning releases from Emacspeak Inc. Emacspeak 37.0 continues the tradition of delivering robust software as reflected by its code-name. Emacspeak 36.0 enhances the audio desktop with many new tools including full EPub support — hence the name EPubDog. Emacspeak 35.0 is all about teaching a new dog old tricks — and is aptly code-named HeadDog in honor of our new Press/Analyst contact. emacspeak-34.0 (AKA Bubbles) established a new beach-head with respect to rapid task completion in an eyes-free environment. Emacspeak-33.0 AKA StarDog brings unparalleled cloud access to the audio desktop. Emacspeak 32.0 AKA LuckyDog continues to innovate via open technologies for better access. Emacspeak 31.0 AKA TweetDog — adds tweeting to the Emacspeak desktop. Emacspeak 30.0 AKA SocialDog brings the Social Web to the audio desktop—you cant but be social if you speak! Emacspeak 29.0—AKAAbleDog—is a testament to the resilliance and innovation embodied by Open Source software—it would not exist without the thriving Emacs community that continues to ensure that Emacs remains one of the premier user environments despite perhaps also being one of the oldest. Emacspeak 28.0—AKA PuppyDog—exemplifies the rapid pace of development evinced by Open Source software. Emacspeak 27.0—AKA FastDog—is the latest in a sequence of upgrades that make previous releases obsolete and downgrades unnecessary. Emacspeak 26—AKA LeadDog—continues the tradition of introducing innovative access solutions that are unfettered by the constraints inherent in traditional adaptive technologies. Emacspeak 25 —AKA ActiveDog —re-activates open, unfettered access to online information. Emacspeak-Alive —AKA LiveDog —enlivens open, unfettered information access with a series of live updates that once again demonstrate the power and agility of open source software development. Emacspeak 23.0 – AKA Retriever—went the extra mile in fetching full access. Emacspeak 22.0 —AKA GuideDog —helps users navigate the Web more effectively than ever before. Emacspeak 21.0 —AKA PlayDog —continued the Emacspeak tradition of relying on enhanced productivity to liberate users. Emacspeak-20.0 —AKA LeapDog —continues the long established GNU/Emacs tradition of integrated innovation to create a pleasurable computing environment for eyes-free interaction. emacspeak-19.0 –AKA WorkDog– is designed to enhance user productivity at work and leisure. Emacspeak-18.0 –code named GoodDog– continued the Emacspeak tradition of enhancing user productivity and thereby reducing total cost of ownership. Emacspeak-17.0 –code named HappyDog– enhances user productivity by exploiting today's evolving WWW standards. Emacspeak-16.0 –code named CleverDog– the follow-up to SmartDog– continued the tradition of working better, faster, smarter. Emacspeak-15.0 –code named SmartDog–followed up on TopDog as the next in a continuing a series of award-winning audio desktop releases from Emacspeak Inc. Emacspeak-14.0 –code named TopDog–was the first release of this millennium. Emacspeak-13.0 –codenamed YellowLab– was the closing release of the 20th. century. Emacspeak-12.0 –code named GoldenDog– began leveraging the evolving semantic WWW to provide task-oriented speech access to Webformation. Emacspeak-11.0 –code named Aster– went the final step in making Linux a zero-cost Internet access solution for blind and visually impaired users. Emacspeak-10.0 –(AKA Emacspeak-2000) code named WonderDog– continued the tradition of award-winning software releases designed to make eyes-free computing a productive and pleasurable experience. Emacspeak-9.0 –(AKA Emacspeak 99) code named BlackLab– continued to innovate in the areas of speech interaction and interactive accessibility. Emacspeak-8.0 –(AKA Emacspeak-98++) code named BlackDog– was a major upgrade to the speech output extension to Emacs.

Emacspeak-95 (code named Illinois) was released as OpenSource on the Internet in May 1995 as the first complete speech interface to UNIX workstations. The subsequent release, Emacspeak-96 (code named Egypt) made available in May 1996 provided significant enhancements to the interface. Emacspeak-97 (Tennessee) went further in providing a true audio desktop. Emacspeak-98 integrated Internetworking into all aspects of the audio desktop to provide the first fully interactive speech-enabled WebTop.

## GMaps: Google Maps On The Emacspeak Desktop

# GMaps: A Google Maps Client For The Emacspeak Desktop

## 1 GMaps: A Google Maps Client For The Emacspeak Desktop

Google Maps provides a powerful service-oriented Directions API and an experimental Places API. module GMaps (part of g-client) implements a new specialized interaction mode that lets you quickly get directions and perform Map searches.

### 1.1 Overview

Module GMaps is now in the Emacspeak svn repository and will be part of the next Emacspeak release. If you are running from SVN, you can start using GMaps today after updating; make sure to

          make config; make

before trying to use it.

#### 1.1.1 Usage:

Run command M-x gmaps to bring up the maps interaction buffer. This buffer provides many special commands for talking to Google Maps – use C-h b in emacs to get a list of key-bindings. Here is a brief summary of how things work:

- You can get directions (walking, driving, by cycling, or public transit) via keystrokes w, d, b, or t. These commands prompt for start and end addresses.
- You can set your current location by hitting c — ; this will be used for Places Search.
- You can specify the radius for Places Search by pressing r and specifying the radius e.g. 500 for 500m.
- You can set up an optional filter for your Places Search by pressing f.
- Pressing n at this point will show you places in your vicinity that match your filter criteria.
- Pressing 'space' on a Place displays details for that place.
- Place details when expanded provide buttons that link you to hours-of-business, Web-site for that place, and the place's G+ page if any.

Note that module GMaps replaces the now obsolete Emapspeak functionality that has been available on C-e?e since early 2005.

## Emacspeak 35.0 (HeadDog) Released

# Emacspeak 35.0—HeadDog—Unleashed!

## 1 Emacspeak-35.0 (HeadDog) Unleashed!

### 1.1 For Immediate Release:

San Jose, Calif., (November 23, 2011) Emacspeak: Redefining Accessibility In The Era Of Cloud Computing –Zero cost of upgrades/downgrades makes priceless software affordable!

Emacspeak Inc (NASDOG: ESPK) --http://emacspeak.sf.net-- announces the immediate world-wide availability of Emacspeak 35.0 (HeadDog) –a powerful audio desktop for leveraging today's evolving data, social and service-oriented Web cloud.

### 1.2 Investors Note:

With several prominent tweeters expanding coverage of #emacspeak, NASDOG: ESPK has now been consistently trading over the net at levels close to that once attained by DogCom high-fliers—and as of October 2009 is trading at levels close to that achieved by once better known stocks in the tech sector.

### 1.3 What Is It?

Emacspeak is a fully functional audio desktop that provides complete eyes-free access to all major 32 and 64 bit operating environments. By seamlessly blending live access to all aspects of the Internet such as Web-surfing, blogging, social computing and electronic messaging into the audio desktop, Emacspeak enables speech access to local and remote information with a consistent and well-integrated user interface. A rich suite of task-oriented tools provides efficient speech-enabled access to the evolving service-oriented social Web cloud.

### 1.4 Major Enhancements:

emacspeak-websearch.el
  Improved search wizards including efficient Google search.
emacspeak-epub.el
  Preliminary EPub support.
emacspeak-magit.el
  Support for git interaction.
emacspeak-pianobar.el
  Pandora radio for the Emacspeak desktop.
emacspeak-dbus.el
  DBus integration to receive network notifications.
emacspeak-woman.el
  Speech-enable Emacs' built-in Man page interface.
Emacspeak-npr.el
  API client for NPR interaction.
emacspeak-librivox.el
  API Client For Free Audio Books from Librivox.

servers/mac
  Support For Mac TTS
Emacs 24 Support
  Updated support for the forthcoming Emacs 24 release.

Plus many more changes too numerous to fit in this margin 󠇿… ∞

### 1.5 Establishing Liberty, Equality And Freedom:

Never a toy system, Emacspeak is voluntarily bundled with all major Linux distributions. Though designed to be modular, distributors have freely chosen to bundle the fully integrated system without any undue pressure—a documented success for the integrated innovation embodied by Emacspeak. As the system evolves, both upgrades and downgrades continue to be available at the same zero-cost to all users. The integrity of the Emacspeak codebase is ensured by the reliable and secure Linux platform used to develop and distribute the software.

Extensive studies have shown that thanks to these features, users consider Emacspeak to be absolutely priceless. Thanks to this wide-spread user demand, the present version remains priceless as ever—it is being made available at the same zero-cost as previous releases.

At the same time, Emacspeak continues to innovate in the area of eyes-free social interaction and carries forward the well-established Open Source tradition of introducing user interface features that eventually show up in luser environments.

On this theme, when once challenged by a proponent of a crash-prone but well-marketed mousetrap with the assertion "Emacs is a system from the 70's", the creator of Emacspeak evinced surprise at the unusual candor manifest in the assertion that it would take popular idiot-proven interfaces until the year 2070 to catch up to where the Emacspeak audio desktop is today. Industry experts welcomed this refreshing breath of Courage Certainty and Clarity (CCC) at a time when users are reeling from the Fear Uncertainty and Doubt (FUD) unleashed by complex software systems backed by even more convoluted press releases.

### 1.6 Independent Test Results:

Independent test results have proven that unlike some modern (and not so modern) software, Emacspeak can be safely uninstalled without adversely affecting the continued performance of the computer. These same tests also revealed that once uninstalled, the user stopped functioning altogether. Speaking with Aster Labrador, the creator of Emacspeak once pointed out that these results re-emphasize the user-centric design of Emacspeak; "It is the user –and not the computer– that stops functioning when Emacspeak is uninstalled!".

#### 1.6.1 Note from Aster,Bubbles and Tilden:

UnDoctored Videos Inc. is looking for volunteers to star in a video demonstrating such complete user failure.

### 1.7 Obtaining Emacspeak:

Emacspeak can be downloaded from Google Code Hosting –see http://code.google.com/p/emacspeak/ You can visit Emacspeak on the WWW at http://emacspeak.sf.net. You can subscribe to the emacspeak mailing list emacspeak@cs.vassar.edu by sending mail to the list request address emacspeak-request@cs.vassar.edu.

The latest development snapshot of Emacspeak is available via Subversion from Google Code Hosting at http://emacspeak.googlecode.com/svn/trunk/

### 1.8 History:

Emacspeak 35.0 is all about teaching a new dog old tricks — andis aptly code-named HeadDog in honor of our new Press/Analyst contact. emacspeak-34.0 (AKA Bubbles) established a new beach-head with respect to rapid task completion in an eyes-free environment.

Emacspeak 31.0 AKA TweetDog — adds tweeting to the Emacspeak desktop. Emacspeak 30.0 AKA SocialDog brings the Social Web to the audio desktop—you cant but be social if you speak! Emacspeak 29.0—AKAAbleDog—is a testament to the resilliance and innovation embodied by Open Source software—it would not exist without the thriving Emacs community that continues to ensure that Emacs remains one of the premier user environments despite perhaps also being one of the oldest. Emacspeak 28.0—AKA PuppyDog—exemplifies the rapid pace of development evinced by Open Source software. Emacspeak 27.0—AKA FastDog—is the latest in a sequence of upgrades that make previous releases obsolete and downgrades unnecessary. Emacspeak 26—AKA LeadDog—continues the tradition of introducing innovative access solutions that are unfettered by the constraints inherent in traditional adaptive technologies. Emacspeak 25 —AKA ActiveDog —re-activates open, unfettered access to online information. Emacspeak-Alive —AKA LiveDog —enlivens open, unfettered information access with a series of live updates that once again demonstrate the power and agility of open source software development. Emacspeak 23.0 -- AKA Retriever—went the extra mile in fetching full access. Emacspeak 22.0 —AKA GuideDog —helps users navigate the Web more effectively than ever before. Emacspeak 21.0 —AKA PlayDog —continued the Emacspeak tradition of relying on enhanced productivity to liberate users. Emacspeak-20.0 —AKA LeapDog —continues the long established GNU/Emacs tradition of integrated innovation to create a pleasurable computing environment for eyes-free interaction. emacspeak-19.0 –AKA WorkDog– is designed to enhance user productivity at work and leisure. Emacspeak-18.0 –code named GoodDog– continued the Emacspeak tradition of enhancing user productivity and thereby reducing total cost of ownership. Emacspeak-17.0 –code named HappyDog– enhances user productivity by exploiting today's evolving WWW standards. Emacspeak-16.0 –code named CleverDog– the follow-up to SmartDog– continued the tradition of working better, faster, smarter. Emacspeak-15.0 –code named SmartDog–followed up on TopDog as the next in a continuing a series of award-winning audio desktop releases from Emacspeak Inc. Emacspeak-14.0 –code named TopDog–was the first release of this millennium. Emacspeak-13.0 –codenamed YellowLab– was the closing release of the 20th. century. Emacspeak-12.0 –code named HeadDog– began leveraging the evolving semantic WWW to provide task-oriented speech access to Webformation. Emacspeak-11.0 –code named Aster– went the final step in making Linux a zero-cost Internet access solution for blind and visually impaired users. Emacspeak-10.0 –(AKA Emacspeak-2000) code named WonderDog– continued the tradition of award-winning software releases designed to make eyes-free computing a productive and pleasurable experience. Emacspeak-9.0 –(AKA Emacspeak 99) code named BlackLab– continued to innovate in the areas of speech interaction and interactive accessibility. Emacspeak-8.0 –(AKA Emacspeak-98++) code named BlackDog– was a major upgrade to the speech output extension to Emacs.

Emacspeak-95 (code named Illinois) was released as OpenSource on the Internet in May 1995 as the first complete speech interface to UNIX workstations. The subsequent release, Emacspeak-96 (code named Egypt) made available in May 1996 provided significant enhancements to the interface. Emacspeak-97 (Tennessee) went further in providing a true audio desktop. Emacspeak-98 integrated Internetworking into all aspects of the audio desktop to provide the first fully interactive speech-enabled WebTop.

## Welcome Press/Analyst Contact Tilden Labrador

For Immediate Release: Monday, August 1, 2011

## Emacspeak Inc. Appoints New Press/Analyst Contact

Tilden Labrador, a young, energetic male yellow Labrador, has accepted the position of Press/Analyst contact for Emacspeak Inc. --- in addition to his primary responsibility of being a fulltime guide-dog.
Hand-picked from an exclusive pool of high-quality caninedates, Tilden brings a large and level head to this position of responsibility. Tilden grew up in Monroe Ct, before going to school at Guiding Eyes For The Blind (GEB), NY. He graduated from GEB's Action program after excelling at obstacle avoidance and path planning in Yorktown Heights, peekskill and White Plains. He rounded out his education with a one-week practicum on the Google campus in Mountain View CA.
Tilden brings a fresh perspective to his new job --- he is the first male Labrador to take on the role of Emacspeak Inc.'s press/analyst contact. Asked how he felt about this unique distinction, he pointed out:
"On the Internet no one knows you're a dog, leave alone what gender you are".
Tilden promises to steer Emacspeak in a manner that would do his predecessors Aster Labrador and HubbellLabrador proud.

Emacspeak Inc (NASDOG: ESPK) --http://emacspeak.sf.net-- announces the immediate world-wide availability of Emacspeak 34.0 (Bubbles) –a powerful audio desktop for leveraging today's evolving data, social and service-oriented Web cloud.

### 1.2 Code Name Note

After 11+ years of loyal service, Hubbell Labrador retired from active duty as a guide-dog on April 4,2011; she stayed on as Emacspeak's press contact for another week before finally leaving us on April 11, 2011 — Epitaph. This release is code named Bubbles in honour of her unflagging service over these last 11 years.

### 1.3 Investors Note:

With several prominent tweeters expanding coverage of #emacspeak, NASDOG: ESPK has now been consistently trading over the net at levels close to that once attained by DogCom high-fliers—and as of October 2009 is trading at levels close to that achieved by once better known stocks in the tech sector.

### 1.5 Major Enhancements:

2. Support for twittering-mode—including logins using OAuth. ●
3. API Client for NPR programming. 🔘
4. Librivox API client. 📚

On this theme, when once challenged by a proponent of a crash-prone but well-marketed mousetrap with the assertion "Emacs is a system from the 70's", the creator of Emacspeak evinced surprise at the unusual candor manifest in the assertion that it would take popular idiot-proven interfaces until the year 2070 to catch up to where the Emacspeak audio desktop is today.

## Emacspeak: In Praise Of The Bookshare API

Bookshare recently released a light-weight API that enables one to implement custom Bookshare clients. Though Bookshare is fully accessible using either Emacs/W3 or Emacs/W3M from within the Emacspeak desktop, browser based interaction often involves more clicks than are absolutely necessary to finish the task at hand.

Welcome module emacspeak-bookshare, a fully integrated Bookshare client for the Emacspeak desktop. Module emacspeak-bookshare provides a special `Bookshare Interaction` mode that provides single keystroke commands for searching, downloading and viewing Bookshare materials from within the comfort of the Emacspeak desktop.

Module Emacspeak-bookshare is now checked into SVN, and will be bundled as part of the next Emacspeak release.To learn how to use Bookshare Interaction on the audio desktop, see command `emacspeak-bookshare`; to view the help for Bookshare Interaction, invoke command `describe-mode` within the Bookshare Interaction buffer.

Read and Enjoy!

## Silence Is Golden

Speech is silvern --- but silence is golden! In the spirit of the above, I just added command `emacspeak-silence` to Emacspeak. You can bind this command to your favorite key for silencing all audio output on the complete audio desktop --- including any active media streams.

## What This Does

Command `emacspeak-silence` stops speech by calling `dtk-stop`. It then runs commands placed on `emacspeak-silence-hook`. Each media player defined by Emacspeak updates hook `emacspeak-silence-hook` with an appropriate action that pauses or resumes that player.

I've also updated the keymaps in `tvr/console-keymaps` to set up the `windows` key on the console to produce `[silence]`, and bound command `emacspeak-silence` to `[silence]` in `emacspeak-keymap.el`.

The net effect is that if you use those console maps, you can just hit the `windows` key whenever you want to silence all audio output; pressing it again will resume any media streams you had active.

Share And Enjoy --- and here's wishing our Press/Analyst contact a very Happy 13th Birthday --- mark it with a palindromic moment at `010212212010` i.e., `Tue Dec 21 01:02:15 PST 2010`

Industry experts welcomed this refreshing breath of Courage Certainty and Clarity (CCC) at a time when users are reeling from the Fear Uncertainty and Doubt (FUD) unleashed by complex software systems backed by even more convoluted press releases.

### 1.6 Independent Test Results:

Independent test results have proven that unlike some modern (and not so modern) software, Emacspeak can be safely uninstalled without adversely affecting the continued performance of the computer. These same tests also revealed that once uninstalled, the user stopped functioning altogether. Speaking with Aster Labrador, the creator of Emacspeak once pointed out that these results re-emphasize the user-centric design of Emacspeak; "It is the user -- and not the computer -- that stops functioning when Emacspeak is uninstalled!".

#### 1.6.1 Note from Aster and Bubbles:

UnDoctored Videos Inc. is looking for volunteers to star in a video demonstrating such complete user failure.

## Emacspeak 32.0 (LuckyDog) Unleashed

# Emacspeak 32.0 --- LuckyDog --- Unleashed!

## 1 Emacspeak-32.0 (LuckyDog) Unleashed!

### 1.1 For Immediate Release:

San Jose, Calif., (May 13, 2010) Emacspeak: Bringing tweet Access For social beings -- ;Zero cost of upgrades/downgrades makes priceless software affordable!

Emacspeak Inc (NASDOG: ESPK) --http://emacspeak.sf.net-- announces the immediate world-wide availability of Emacspeak 32.0 (LuckyDog) -- ;a powerful audio desktop for leveraging today's evolving data, social and service-oriented Web cloud.

### 1.2 Investors Note:

With several prominent tweeters expanding coverage, NASDOG: ESPK has now been consistently trading over the net at levels close to that once attained by DogCom high-fliers --- and as of October 2009 is trading at levels close to that achieved by once better known stocks in the tech sector.

### 1.3 What Is It?

Emacspeak is a fully functional audio desktop that provides complete eyes-free access to all major 32 and 64 bit operating environments. By seamlessly blending live access to all aspects of the Internet such as Web-surfing, blogging, social computing and electronic messaging into the audio desktop, Emacspeak enables speech access to local and remote information with a consistent and well-integrated user interface. A rich suite of task-oriented tools provides efficient speech-enabled access to the evolving service-oriented Web cloud.

### 1.4 Major Enhancements:

1. Updated URL Templates for rapid Web access. ♁
2. BBC iPlayer support ☢
3. Updated EPub support ✍
4. Emacs 24 support ♺

Plus many more changes too numerous to fit in this margin ∞

### 1.5 Establishing Liberty, Equality And Freedom:

Never a toy system, Emacspeak is voluntarily bundled with all major Linux distributions. Though designed to be modular, distributors have freely chosen to bundle the fully integrated system without any undue pressure --- a documented success for the integrated innovation embodied by Emacspeak. As the system evolves, both upgrades and downgrades continue to be available at the same zero-cost to all users. The integrity of the Emacspeak codebase is ensured by the reliable and secure Linux platform used to develop and distribute the software.

Extensive studies have shown that thanks to these features, users consider Emacspeak to be absolutely priceless. Thanks to this wide-spread user demand, the present version remains priceless as ever --- it is being made available at the same zero-cost as previous releases.

At the same time, Emacspeak continues to innovate in the area of eyes-free social interaction and carries forward the well-established Open Source tradition of introducing user interface features that eventually show up in luser environments.

On this theme, when once challenged by a proponent of a crash-prone but well-marketed mousetrap with the assertion "Emacs is a system from the 70's", the creator of Emacspeak evinced surprise at the unusual candor manifest in the assertion that it would take popular idiot-proven interfaces until the year 2070 to catch up to where the Emacspeak audio desktop is today.

## AsTeR --- Audio System For Technical Readings

Almost exactly 16 years to the date after presenting AsTeR --- Audio System For Technical Readings --- to the CS Faculty at Cornell for my PhD, I released the source code as Open Source --- thanks to Prof. David Gries at Cornell for approving this release.

The sources are checked into GoogleCode project aster-math --- unfortunately, the name AsTeR was unavailable since there is an unrelated project of the same name at SourceForge.

So you might well ask: why 16 years later, and why now? The honest answer is No good reason, except that after graduating from Cornell, I decided that I would work on newer projects, and consequently had no cycles to support the AsTeR code base. Nothing has changed in that context, nor is it likely to change in the coming future; however I get requests off and on from different parts of the Web from teachers and students alike who have seen my PhD thesis, played with the demos, and wish to study the sources.

## What You'll Find In The Sources

The code has not been actively developed since I finished my work at Cornell; however, over the years, I 've ensured that the system starts up and runs on Linux using the Open Source CLisp environment. The only text-to-speech engine that is supported is the hardware DECTalk --- though it should be a small matter of programming to support the various Emacspeak speech servers. If you do checkout the source code, start by looking at the README file which contains brief instructions on getting started. Feel free to use the Emacspeak mailing list for now if you wish to discuss the code --- if the traffic justifies it, we can later create a project-specific list.

## Emacspeak, The World's Fonts And Braille

Emacspeak has supported the editing of Unicode text for over a year now --- thanks to the patches fromLukas. With the support now mature, I have now retired option `emacspeak-unibyte` --- Emacspeak no longer supports running Emacs in `unibyte` mode. Note that this aligns Emacspeak with Emacs 23.2 which obsoletes `unibyte`mode.

When you edit text containing Unicode characters, Emacspeak uses the name of the character as found in the description file from the Unicode consortium --- you will need to download and install that data file as documented in Emacs:

          describe-char-unicodedata-file is a variable defined in
          `descr-text.el'.
          Its value is
          "/usr/local/share/unicode/UnicodeData.txt"

          Documentation:
          Location of Unicode data file.
          This is the UnicodeData.txt file from the Unicode Consortium, used
          for
          diagnostics.  If it is non-nil `describe-char' will print data
          looked up from it.  This facility is mostly of use to people doing
          multilingual development.

          This is a fairly large file, not typically present on GNU systems.
          At the time of writing it is at the URL
          `http://www.unicode.org/Public/UNIDATA/UnicodeData.txt'.

          You can customize this variable.

          This variable was introduced, or its default value was changed, in
          version 22.1 of Emacs.

With the Unicode data file in place, Emacspeak can announce names of characters from all of the world's fonts --- this includes Braille. As an added convenience, I have integrated package `toy-braille.el` found on the Emacs wiki into the Emacs codebase and defined a new interactive command `emacspeak-wizards-braille` --- if you find yourself using it often, you can bind it to a key of your choice. Command `emacspeak-wizards-braille` prompts for thestring to Braille and produces a Grade-1 representation of the specified string using the appropriate Unicode characters.

## Emacspeak Servers --- Catching Up With Debian And Ubuntu

Over the last couple of years, the TCL world has moved on from TCL8.3 to TCL8.4 --- this introduces a set of needed changes to how Emacspeak servers such as Espeak and ViaVoice-Outloud work. I have finally decided to break backward compatibility with TCL8.3 and move things forward to TCL8.4, now that all the Linux distributions have settled on TCL8.4.

Also, sometime in 2005, I transitioned all of the server Makefiles to use libtool --- at the time, it made compilation of the servers somewhat easier. However, this has tended to make things more complex over time, thanks to changes in libtool. I've now dropped the libtool dependency in favor of using simpler Makefiles --- thanks William Hubbs of Gentoo!

### ViaVoice Outloud Server For Emacspeak

The Voxin package from Guilles continues to be the easiest means of obtaining high-quality text-to-speech on Linux. Installation of that package went smoothly on Hardy; however on Jaunty, things did not go so well, see notes below for things to watch out for on Jaunty or later.

- The libstdc++ compat libraries ended up not getting installed on Jaunty. Consequence, ViaVoice produces a warning asking you to install the ViaVoice RTK, even though it's already installed. I ended up rescueing the compat libs from my Hardy build. Perhaps we should put up a simple tar.gz file that drops those libs into /usr/lib?
- Alsa is configured to use pulseaudio on Jaunty. An unfortunate consequence is that when ViaVoice runs, it sounds like a stereo channel played as mono, i.e. the speech slows down and the voice sounds wrong. The fix is to create a .asoundrc file in your home directory --- you can use the sample in linux-outloud/ASOUNDRC as a starting point. To see if pulseaudio is intervening in your setup, do :aplay -v wav file --- to see the set of alsa plugins that are participating in audio output.

### ESpeak And Emacspeak

The ESpeak server does not get affected by the above problem. However, unless you install package alsa-oss and invoke that server as :aoss tcl espeak the server will fail to start if some other application is using the audio device.

### Software Dectalk And Emacspeak

This still needs testing under newer Linux distributions --- I've not used it in a long time and dont have the libs installed any more.

## Launching Favorite Media Via Hot Keys

## Launching Oft-Played Media On The Complete Audio Desktop

Command `emacspeak-multimedia` lets you launch all forms of local and remote media. However this stil requires you to specify the media location --- and this requires a bunch of keystrokes that you end up repeating for selecting media that you play often, e.g., from your private music collection. No more extra keystrokes, you can now have Emacspeak automatically assign suitable hotkeys for launching `emacspeak-media` onyour favorite audio collections.

## How It Works

- Customize Emacspeak option `emacspeak-media-location-bindings` using Emacs' Custom interface:

            M-x customize-variable ---

  press `C-H V` in emacspeak.
- Click `ins` to insert a key/location pair.
- Click `save` to persist the binding.
- pressing the assigned hotkey will automatically launch `emacspeak-multimedia` on the predefined location --- emacs will prompt you with regular filename completion for media resources found in that directory.

In my own case, I have favorites defined on `hyper-<n>` so I can define upto 10 hotkey assignments for media locations.Once launched, Emacspeak automatically switches to the media player buffer; note that this is different from how `emacspeak-multimedia` normally works. The justification: this hotkey interface is ideally suited to remote controls, joysticks, and any other peripheral via which you can deliver input to Emacs.

We'll be around during most of Google I/O, so if you are interested in eyes-free interaction ranging from Emacspeak to Fire-Vox, or anything else eyes-free, feel free to grab us in the hallways. Looking forward to seeing you there!

## Abstract: Looking Beyond The Screen

## Looking Beyond The Screen

Project Eyes-Free aims to enable fluent eyes-free use of mobile devices running Android. Target uses range from eyes-busy environments like in-car use to users who are unwilling to or incapable of looking at the visual display --- see For The Blind, Technology Does What A Guide Dog Can't, NYTimes, January 4, 2009, for a high-level overview. As described in that article, we are releasing components from project Eyes-Free as they become ready for end-user deployment. This announcement marks the first public release of the eyes-free shell on the Android Marketplace, though the underlying source code has been available for some time from the code repository at Google Code Hosting.

Here is a brief overview of the end-user affordances provided in this release:

1. An Eyes-Free Shell for conveniently launching talking applications.
2. A collection of useful talking applications that turn an Android phone into an eyes-free communication device --- see subsequent sections for an overview of these applications. Note that thes eapplications have been written to be both useful to end-users as well as to help the developper community to come up to speed with developing eyes-free applications for Android.

We will be uploading video tutorials demonstrating the use of these applications to YouTube --- please see the project Web site for these links as they become available.

### Talking Dialer

A key innovation is the use of the touch screen to enable one-handed, eyes-free dialing of phone numbers using the touch screen --- see Miguel Helft's NY Times article cited above for a good layman's description of the technique. The talking dialer comes with a talking phone-book that enables users to quickly select a desired contact using the touch screen.

### Knowing Your Location

This mini-application announces your present location based on information acquired via GPS and the cell network. It speaks your current heading using the built-in magnetic compass, looks up the current location on Google Maps, and announces the location in terms of a nearby address and street intersection.

### Device State

This mini-application announces useful information such as battery state, signal strength, and availability of WiFi networks.

### Date And Time

This mini-application provides single-touch access to current date and time.

## Toward an Accessible Democracy --- White House Moderator AxsJAXed

## Toward An Accessible Democracy --- White House Moderator AxsJAXed!

This is not directly Emacspeak related --- except that it is useful for emacspeak users. Project AxsJAX, combined with Fire-Vox does for Web-2.0 applications what Emacspeak does for applications written within Emacs. Charles and I just announced AxsJAX For White House Moderator --- an AxsJAX extension that applies W3C ARIA to the White House Moderator.I'll append the article below:

## An ARIA For The White House Moderator

Google-AxsJAX was launched in late 2007 as a library for access-enabling Web-2.0 applications. Since then, we have released accessibility enhancements for many Web-2.0 applications via the AxsJAX site as early experiments that have eventually graduated into the products being extended. Today, we are happy to announce an early AxsJAX extension for Google Moderator that enables fluent eyes-free use of Google Moderator as seen on the White House site.

### HowTo: Brief Overview.

For details on installing and using AxsJAX extensions, see the AxsJAX FAQ. Briefly, you need Firefox 3.0 and a screenreader that supports W3C ARIA. Users who do not have a screenreader installed can most easily experience the results by installing Fire Vox, a freely available self-voicing extension for Firefox.

With the AxsJAX extension in place, you can use Google Moderator via the keyboard, with all user interaction producing spoken feedback via W3C ARIA. Here is a brief overview of the user experience:

1. The user interface is divided into logical panes --- one listing topic areas, and the other listing questions in a given topic. At times, e.g., before a meeting, you may find an additional Featured Question pane that shows a randomly selected question that you can vote on.
2. Users can ask new questions under a given topic, or give a thumbs-up/down to questions that have already been asked.
3. Use the left and right arrow keys to switch between the two panes. You hear the title of the selected pane as you switch.
4. Use up and down arrows to navigate among the items in the selected pane. As you navigate, you hear the current item.
5. Hit enter to select the current item.
6. The current item can be magnified by repeated presses of the + (or =) key. To reduce magnification, press the - key.
7. When navigating the questions in a given topic, hit y or n to vote a question up or down.
8. When navigating items in the topic pane, hit a to ask aquestion. Once you confirm your request to post the question, it will show up in the list of questions for that topic so that others can vote that question up or down.

Please use Google Group Accessible for providing feedback on this AxsJAX extension.

Share And Enjoy--

Raman and Charles.

## Emacspeak Webspace Goodies

Module `emacspeak-webspace` has a few new goodies on offer. If you activate WebSpace Headlines to obtain a continuously updating ticker of headlines, you may also at times want to find one of the headlines you heard go by and read the relevant article. Command `emacspeak-webspace-headlines-view` bound by default to `C-RET` pops up a special Headlines buffer that lists all the currently available headlines. This is a regular Emacs buffer that uses a special major mode called emacspeak-webspace-mode. This modeprovides special commands to open a feed at point, follow hyperlinks etc.; use Emacs' online help facilities to learn how this buffer works.

Mode emacspeak-webspace-mode is also used toadvantage in browsing information retrieved via the Google AJAX APIs described in the previous set of articles on this blog. Google Reader subscribers can now view the subscription list in a Webspace buffer via command `emacspeak-webspace-reader`. Additionally, command emacspeak-webspace-google provides a more convenient interface to command `gweb-google-at-point` --- in addition to speaking the snippet from the first search hit, this command places the first four results in a special Search Results buffer that is put in Webspace mode.

Search And Enjoy!

## Emacspeak-WebSpace Just Got A Lot Faster

### In Praise Of Google AJAX APIS

New module `gfeeds.el` (part of Library `g-client`) now implements a Lisp interface to the Google AJAX FeedSearch API. An immediate consequence of this is that module `Emacspeak-WebSpace` just got orders of magnitude faster --- not that it was slow to start with:-)

Feed And Enjoy!

## In Praise Of The Google Search AJAX API

## In Praise Of The Google AJAX Search API

Emacspeak has always provided Google Search with a single keystroke from anywhere on the audio desktop. But with the coming of the Google AJAX Search API it becomes possible to integrate Google Search at a far deeper level into your fingertips! The AJAX API demonstrates the true speed of Google Search, since you dont need to wait for an HTML page to download and render --- results are served as a light-weight JSON data structure.

## What You Can Now Do

Module `gsearch` (part of the `g-client` package) provides an interactive command `gsearch-google-at-point` --- I have this bound to key `hyper-/` in Emacs. Executing this command from anywhere inside Emacs does the following:

- Grabs word under point, and prompts in the minibuffer for a search-term --- with the word we just grabbed as the default.
- Fetches other relevant search terms in the background via Google Suggest, and makes these available via Emacs' minibuffer history mechanism. Use keys `M-n` and `M-p` to cycle through these if needed.
- Hitting `ENTER` performs a Google Search using the AJAX API, and displays the title and content snippet for the first search result.
- Executing command `gsearch-google-at-point` subsequently at the same location opens the first search result.

Search And Enjoy!

## Tutorial: Enhancing Web 2.0 Usability Using AxsJAX

You can watch a video of the tutorial Charles and I gave as part of the Google Open Source series on July 14. Emacspeak users can play the video by pressing `e e` on the above link and specifying `emacspeak-m-player-youtube-player` when prompted.

### Abstract

Google is the Web's premier creator of user-friendly Web 2.0 applications, and I have long viewed it as part of our mission to do for users in the long tail (AKA users with special needs) what we've achieved for the mainstream user. Accessibility 2.0 is now a hot topic on the Web --- and we would like to move from a world where AJAX applications were a straight No-No with respect to blind users to a world where these same technologies are used to enhance their usability for everyone.

Google-AxsJAX is an Open Source framework for injecting accessibility for users with special needs --- and more generally, usability enhancements --- into Web 2.0 applications. In this TechTalk, Charles Chen and I give a hands-on tutorial on using AxsJAX to enhance the usability of Web 2.0 applications. The tutorial covers the following:

- A brief introduction to the additional opcodes introduced by W3C ARIA to the assembly language of the Web (AKA HTML+JavaScript).
- AxsJAX library abstractions built on the above that help Web developers generate relevant feedback via the user's adaptive technology of choice.
- Steps in creating fluent eyes-free interaction to Web applications, including enabling rapid access to parts of a complex Web page.

This tutorial focuses on solutions we've already built and deployed both within shipping products and as early end-user experiments. Google products that we will cover include:

- Google WebSearch
- Google Reader
- Google Books
- GMail and Google Talk
- Google Scholar
- Google Sky

And time permitting, we might even demonstrate how I now make up for all the time I save thanks to an efficient eyes-free auditory user interface by playing JawBreaker and reading XKCD via their AxsJAXed versions.

Note that writing AxsJAX enhancements to Web applications can help you win bragging rights and cool swag! The goal of this hands-on tutorial is to help you get there faster!

## ProcEd: A Speech-Enabled Task Manager For Emacs

For the last 10 years or so, view-process-mode has been my task manager of choice for monitoring and controlling the state of processes on the Emacspeak audio desktop. As of Emacs 23, AKA Emacs from CVS, that module does not work anymore --- in fact it has not been updated for several years. On the positive side, Emacs now bundles module ProcEd --- a task manager that does for processes what module DirEd does for files and directories. As of this morning, proced.el is fully speech-enabled by Emacspeak. You can install module ProcEd for Emacs 22 by obtaining the file from the Web --- you can easily find it via Google.

Share And Enjoy ... And have a great July 4th Holiday!

## Leveraging Web 2.0 Design Patterns For Enhanced Accessibility

As promised, here is a link to the Youtube video of the talk on Leveraging Web 2.0 Patterns For Accessibility given during Google I/O on May 28, 2008 in San Francisco. Emacspeak users can play the video by hitting `e e`on the link, and specifying `emacspeak-m-player-youtube-player` when prompted. You can find the downloadable slides used during the talk along with other session material on the Google I/O page for this session.

## Talk Details

Leveraging Web 2.0 Design Patterns For Enhanced Accessibility T. V. Raman (Google)

HTML DOM+ JavaScript constitutes the assembly language of Web Applications. Access To Rich Internet Applications --- ARIA --- adds in a couple of additional op-codes for helping Web applications better communicate with adaptive technologies such as screenreaders. How do we now push the envelope with respect to Web applications and adaptive technologies such as screenreaders and self-voicing browsers in a manner similar to what we as Web developers have collectively achieved for the mainstream user? This session will demonstrate programming techniques that help Web developers experiment with and build in the latest accessibility techniques into their Web applications. We will base this session on project Google-AxsJAX. Developers should know JavaScript, but session doesn't require deep AJAX hackery.

## Emacspeak On Thinkpad X-61 Running Gutsy (Ubuntu 7.0)

I recently upgraded to a Thinkpad X-61 running Gutsy --- here are some brief notes on the move. In summary, all is well, and I like Gutsy running on the X-61.

Here are things to be aware of both from a hardware and software perspective. All of this is with X and GNOME turned off; note that some of the tips e.g. turning off the display as described here, will cause havoc with X.

- The X-61 display can be turned off using `vbetool`

      vbetool dpms off

  for turning off the display, and

      vbetool dpms on

  for turning it back on again.
- If you suspend to memory etc., make sure to add the appropriate `vbetool` command to the relevant script in `/etc/acpi/resume.d`.
- Gutsy is running ALSA 1.0.15, and to date, I've not had any trouble with the ViaVoice Outloud TTS engine in this environment. Make sure to play with `amixer` --specifically run command

      amixer controls

  to understand all the various switches and controls exposed by the audio hardware on the X61. Here are some of the things that were noticeably different that are worth mentioning:
  1. The PC speaker can now be manipulated via ALSA.
  2. The X-61 has two input sources. If you plug in an external mike, make sure to set both input sources to the microphone --- as opposed to leaving one or both of them to be either `internal mic` or `mix`. Specifically, plugging in an external mike does not disable the internal microphone.
  3. For some bizarre reason, it's possible to turn off the headphone output--- but you cannot control its gain.
- Kernels later than 2.6.21 do much better with respect to power management, and this really shows on the X-61. With the LCD off, my X61 claims it'll run for 7.5 hours; if you turn off the wireless and USB1.1 as well, it claims it can go for over 8.5 hours.
- Emacs versions: I'm running out of CVS AKA Emacs 23--- but the `emacs-snapshot` or `emacs22` Ubuntu packages appear to mostly work as well. One irritation with some of the prepackaged bundles of Emacs under Ubuntu is that they dont install the Emacs Lisp sources, and this will bite if you try compiling packages like Emacs/W3.

All in all, the upgrade to Gutsy was mostly painless --- other than having to figure out the usual nits about the new hardware. The `/proc/acpi/ibm` support is further along but not yet complete--- as an example `/proc/acpi/ibm/video` does not yet control the state of the LCD --- and you cannot query the state of the display reliably through that interface.

## Emacspeak Goes Social

## Leveraging The Benefits Of Free Speech!

For Immediate Release:
April 1, 2008

## Live From San Jose ... Emacspeak Goes Social!

Investors and users alike welcomed today's announcement that Emacspeak (NASDOG:ESPK) would be going social --- Going Social is better than Going Postal!

As a pioneer in the space of eyes-free information access, and a firm believer in free speech and free software, Emacspeak will now help users go social speech-free --- all users need do is to use the system. When in use, the free-social features of Emacspeak will talk to others on your behalf, answer inane questions, and contribute to the community by in its turn asking even more inane questions of everyone else. In a repeat of the network effect that has led to the resounding success of systems like the World Wide Web and The Blogosphere, these viral features in Emacspeak are expected to win ones running instance many social connections. The longer one uses these features, the deeper one's social graph --- going forward, the information encapsulated in these social graphs will be converted to ever-increasing stacks of small pieces of green paper.

## Coming Soon!

As these features are launched over the next few weeks, expect Emacspeak generated conversation streams to show up everywhere ranging from Twitter streams to random email messages that you can usefully use to forward to spammers. This innovative approach to communication finally adds value to spam --- and is being hailed as the next biggest business model to hit the ether. By making such content available on the Internet, the system will foster the long term human goal of organizing and searching all the world's ignorance to make it universally accessible --- thereby bringing ignorance on par with knowledge!

## Emacspeak WebSpace --- Interaction-Free Information Access

A few months ago, I started an Emacspeak module called `emacspeak-webspace` that is now ready for wider use. The goal of this module is to unobtrusively fetch useful information from the Web and communicate it at those times that one is context-switching among tasks. I gave a talk on user interaction at the last Hackers Conference in November; in the same session, there was another talk whose gist was a plea for less human-computer interaction --- motivation: User Interfaces are nice, but wouldn't it be nice if one didn't have to explicitly interact with the machine to get information? The speaker coined the term Zen interfaces in that context, something that stuck in memory long after the talk.

I built that thought into module `emacspeak-webspace`. Conceptually, it consists of smart fetchers that fetch information asynchronously from the Web, and smart displayers that communicate this information at appropriate times. These are detailed below.

### Fetchers

There are two fetchers at present:

Weather
  Fetches current weather conditions for your location.
News
  Fetches headlines from a customizable collection of ATOM and RSS feeds.

Note that this module is not intended to be an RSS or ATOM feed-reader; for that, use module `greader` --- an API-based Google Reader client that is bundled with Emacspeak.

### Communicating Useful Information Usefully

With the information in hand, the next question is how does one communicate this information usefully, and what does at the appropriate time mean? Things toavoid:

Interaction-Free
  Do not require explicit user action to hear the information.
Avoid Chatter
  Avoid creating an auditory user interface that chatters at the user all the time.

These are conflicting constraints. Notice that in a visual interface, one can meet the interaction-free requirement by displaying the information in a toolbar or sidebar and allow the user to ignore or absorb the information at will.

Emacspeak uses Emacs' header-line to display the continuously updating information. This meets the interaction-free requirement. The header line updates every time Emacs updates its display, and automatically speaking it would produce too much feedback. But Emacspeak doesn't automatically speak the header-line; it only speaks it when there is a context-switch.

### How To Use

Here is how I am using `emacspeak-webspace` at present:

Weather
  Activate weather display in the `calendar` and `scratch` buffers.
News
  Activate feed headlines in selected `shell` buffers.

You hear the updated information when switching to buffers where the webspace display is active.

### Activating WebSpace Displays

Webspace displays are activated via the following commands; all Webspace displays will be placed by default on prefix key `hyper-space`

- `emacspeak-webspace-headlines`: `hyper-space h`
- `emacspeak-webspace-weather` `hyper-space w`

## Announcing: The Coming Of Piglets To The Emacspeak Desktop

This is to announce a new emacspeak module called Piglets that brings together Emacs and Firefox to create a powerful framework for authoring Web interaction wizards.

## Why Piglets?

You might well ask Why Piglets?, and might conjecture that PIGLETS might stand for Powerful Internet Gadgets for a Light-Weight Talking System. You might conjecture that the Emacspeak mascot likes pig-ears; or you might even think of attributing it to the fact that my friend and colleague Charles Chen and creator of Fire Vox was born in the year of the pig. But you'd be mostly wrong in all of the above.

Piglets on the Emacspeak desktop are the result of having two large (and powerful) software pigs connect over a socket. A few months ago, I blogged here about MozREPL and how it allows me to Put The Fox In A Box. Piglets mark the completion of the Emacs/Firefox integration that started with Firebox. Once you install Fire Vox, the free self-voicing extension for Firefox, piglets become a versatile means to leverage the self-voicing Fire-Vox/Firefox DOM from the comfort of the emacspeak environment.

## What You Need

Caveat: ALL of this is early experimental software --- and you'll need to tweak things for your environment to get things working.

- A version of Emacspeak from the subversion repository.
- Check the installation of the `servers/python` files in your Emacspeak installation.
- Confirm that the `HTTP` wrapper for the TTS servers works. You can most easily do this by running:

            # Start the HTTPspeech server
            # from emacspeak/servers/python
            python HTTPSpeaker.py  outloud 2222 &
            # you can replace outloud with dtk-exp
            # but the bindings to other TTS  servers is not defined for now
            # Run wget to test the speech server:
            wget --post-data='speak:hello world' localhost:2222

  If all is well, you should here the TTS engine say Hello World

  Do not proceed if the above does not work.

- Install Fire-Vox and configure it to use the Emacspeak TTS server. You can do this with ORCA providing the feedback. Alternatively, once you have installed Fire-Vox, shutdown Firefox and then edit your `~/.mozilla/firefox/default/prefs.js`

            user_pref("firevox.LastWorkingTTS", 4);

- The above sets up Fire-Vox to use the running HTTP speech server you started earlier.

## Loading And Running Piglets

The Piglets framework is implemented in module `emacspeak-piglets.el`. There is a Fire-Vox binding in module `emacspeak-firevox.el` and a binding to the JawBreaker game in `emacspeak-jawbreaker.el`.

## How Does It Work?

When you get the various pieces configured and working, here is how things work:

- Piglets place you in a special interaction buffer in Emacs.
- Typing keys in this buffer go to Firefox.
- Control keys send commands to Firefox using MozREPL.
- The latter is most useful in conjunction with Web 2.0 applications that have been AxsJAXed.
- Additional commands give access to FireFox features such as the URL bar. As an example, hit `C-w` and type the phrase you'd like to go into the address bar --- either a URL or a search term. As an example, try typing XKCDComic. This will automatically do a Google Lucky Search (thanks to FireFox magic) and open the XKCD site.
- But wait, there's more! Because XKCD has been AxsJAXed, you will hear Fire-Vox automatically speak the comic strip and its associated transcript. Hit `?` in the FireFox interaction buffer to hear the available keystrokes for this AxsJAXed application; in general, `?` brings up keyboard help for AxsJAXed applications.

## ToDos:

These are some todos that I plan to get to eventually --- if you have coding cycles to contribute, feel free to work on these.

- Create an HTTP binding to the TTS servers using TCL and the TCL HTTP libraries. This will eliminate the dependency on the Python wrapper I originally wrote for ORCA in fall 2005.
- Write more Piglets.
- Make installation and configuration simpler.
- Test installation and configuration of the various pieces.

## Web Accessibility And Usability: Coming Back To The Basics

The Nielsen Norman Group has made available a detailed report on accessibility, which includes the results of several usability tests --- see Going Beyond Alt Text. It's a very good read, and though its conclusions might be depressing to people coming to this area from the outside --- they should be no surprize to users who have been trying to use the Web via spoken output over the last 10 years. From the perspective of the Emacspeak user who lives in a specialized browsing environment that is optimized for performing oft-repeated tasks, there are several interesting take-aways from this report:

- Though so-called Web Accessibility Standards have attempted to focus on the behavior observed when using screenreaders with mainstream browsers, that thread of work appears to be achieving little with respect to the real metric of task completion. As technologists, we would all do well to remember that users come to the Web, and Web Access solutions not to use the browser but rather to complete one or other task.
- As described in Specialized Browsers and The Web The Way You Want It, task-oriented access and specialized user-optimized web tools have been around since the inception of the Web.
- Though the Nielsen study asked users to carry out each of the given tasks by going to a given Web site, it would be interesting to see how such tasks work out in the Emacspeak environment. It's a given that an emacspeak user trying to buy a music CD at an online store would run into a brick wall fairly quickly (see, even online stores are made of brick and mortar;-)). However, as an Emacspeak user I'd never do that I'd either go to Amazon's highly efficient Amazon Accessible Store or faster yet, type an appropriate query at Google and click on the relevant Ad that sports a Google Checkout badge.
- And more interestingly, it would be interesting to carry out a follow-up user study to compare the rate of task completion as well as observed efficiencies/inefficiencies between users of Emacspeak and generic browser/screenreader combinations for tasks such as:
  1. Play NPR news from the last hour.
  2. Play your local NPR station.
  3. Play BBC News from the last hour.
  4. Skim the top stories from CNN.
  5. Look up today's stock market numbers for the major indices.
  6. And items too numerous to enumerate in this margin.

## Directions Using Public Transport From Google Maps

In the spirit of adding a smart URL template to enhance the Emacspeak Web Command Line for useful tools I discover ...

I just checked in a `Public Transit Via Google Maps` tool into the Emacspeak SVN repository. You specify trip details in the form start to destination e.g., 2715 La Terrace Circle 95123 to San Jose Airport and get back a filtered view that shows the information you want. Note that clicking on the link in this blog will give you the entire page, which is fairly easy to navigate. But having a smart filter in Emacspeak makes it that much more efficient to use.

## AxsJAX, Speech-Enabled Games And Auditory User Interfaces

This is not part of Emacspeak, but is relevant to emacspeak users given that:

- Speech-enabled games have proven to be a successful means of discovering AUI techniques that work, beginning with the speech-enabled version of Tetris.
- The emerging Emacs to Firefox connection using module `emacspeak-moz.el` and `mozrepl`
- The ability to run Fire Vox with the Emacspeak speech servers --- look for a blog post on that soon.

Charles Chen and I recently released a JavaScript powered framework for access-enabling AJAX applications --- see AxsJAX.Along with access-enabling useful applications such as Google WebSearch and Google Reader, we also access-enabled JawBreaker, a popular game much in the spirit of Tetris --- but without a ticking clock. See AxsJAX showcase for pointer to this and other Web-2.0 applications that have been AxsJaxed.

## Emacspeak Video Demo: Looking Up The Weather

In the first of a sequence of posts demonstrating live emacspeak user interaction, I'll give an overview of what it feels like to use Emacspeak's powerful Web Command Line provided by its rich collection of web gadgets made up of search wizards and smart url templates

Here are a few things to note about this and all the subsequent video demos in this series:

- All demos were recorded using recordmydesktop on an Ubuntu laptop running Linux (Ubuntu Dapper).
- The text-to-speech is produced by the IBM ViaVoice engine, this can now be purchased from a couple of sources in the US and Europe.
- All demos are recorded with the speech rate at which I use Emacspeak. These demos are primarily intended to show the efficiency of the environment, and slowing down the speech would detract significantly from that goal.
- Frequent users of text-to-speech will still find the output comprehensible. For the rest, you can match it up with what you see on the screen ;-)
- Careful listeners will notice some jitter/clipping in the audio --- this appears to be an artifact of using recordmydesktop that I was unable to eliminate.
- In each of these articles, I'll enumerate the actions I take, and their effect. I'll enumearate actual keystrokes, but I suggest readers focus more on the atomic commands being executed, rather than individual keypresses.

### Looking Up The Weather

Looking up current weather is a sufficiently common action where browsing to a weather site, typing in ones zip-code and reviewing the resulting page is three steps too many. This is also why most modern desktop environments provide gadgets that display such live information with minimal user intervention. This first video shows Emacspeak smart url `RSS Weather From Wunderground`in action.

Here is the RSS Weather Demo. This is an OGG/Theora video and should play with tools like `mplayer`. The table below shows a brief description of each user action and its effect.

Action | Key | Effect
--- | --- | ---
Access Gadgets | C-e u | Prompts for gadget
Pick Weather Gadget | rss tab | partial input completes to RSS Weather From Wunderground
Pick Default Location | return | CA/SanJose
|  | Speaks weather forecast
Quit | q | Stops speech, dismisses weather forecast, and speaks current context. In this case the shell becomes current and you hear the relevant information.

### A Transcript Of What You Hear

Users who could see the video half of this demo but were not frequent text-to-speech users reported that it would be useful to see a transcript of what is being spoken. I'm revising this entry to have an annotated transcript. Note that the transcript may not be accurate to the last word, since I'm typing it in by hand; however it should give one a sense of what information emacspeak chooses to speak.

Access Gadgets
  The spoken prompt is Resource:.
Pick Gadget
  You hear me type RS and then you hear Emacspeak completing my input to RSSWeather. Half way through that utterance, I know it's found the right gadget, so I hit enter, and that stops the utterance RSSWeather half-way through and speaks the next prompt. Notice that you also hear auditory icons to indicate that a prompt input area just opened.
Location
  With the gadget now selected, you hear the City/State prompt generated by the weather gadget. It also produces a default location of CA/San_Jose. In the demo, you hear the State/City prompt, along with the default value. I hit enter midway through that utterance, again the speech flushes immediately. The gadget now has enough information to do its work; it pulls the RSS feed from Wunderground, converts it to XHTML (using XSLT) and displays the page using Emacs/W3. Once displayed, it starts speak the forecast you see on the screen.
Forecast
  Here is a rough transcript of what you hear as the weather forecast is spoken. The forecast starts with the words: Conditions 73 degrees F Partly cloudy 4:50pm PDT August 18 ... This is in a lower-pitched (deeper) voice since it was generated from the title of the corresponding RSS item. Emacspeak uses Aural CSS to produce such audio formatted information. The contents of the item are spoken in the default voice starting with the utterance Temperature 73 degrees F 23 degrees C ... Conditions partly cloudy ... When I've heard enough, I hit `q` to quit.
Quit
  When I quit the weather gadget, a number of things happen.
  - You hear auditory icon close-object to indicate the weather forecast being dismissed.
  - You hear context information indicating that the Emacs shell buffer has now become current.
  - For this context information, you hear it speak the working directory of the shell buffer and the word shell

## Emacspeak And GMail

See this article by my Google colleague Srinivas Annam that outlines the availability of GMail Filters from the basic HTML interface. This was the final piece that remained to convince me to use my GMail account for email --- now, keeping the GMail Inbox clean and free of clutter has become a snap.

To go with this, I've added a few smart URL templates to Emacspeak's Web Command Line. Once you've signed in, you can use template `GMail Search` to type a search term, and find matching mesages. Note that GMail uses CSS class `msg` to tag the actual contents of a message. You can use this to advantage by hitting `e c` on a message link, and specifying `msg` as the class value to filter the message.

At some point I'll add a couple of Emacspeak wizards for creating filters; the present HTML interface is still a bit too click intensive for my liking. But cudos to Srinivas for doing the hard work that lets me discover the pain points in the HTML interface; until now these were completely invisible to me since I couldn't use GMail from the Emacspeak environment.

Emacs/W3 note: Note that signing in to GMail from the main GMail screen defeats W3. An easy work-around, and something that is more efficient anyway is to use the `glogin.xml` form found in Emacspeak --- use `C-e ?/` in Emacspeak to pick that form. Once you're signed in to Google, you can:

- Open your inbox
- Perform searches to find the message you want

## AMixer And Emacspeak: Controlling The Sound Card

In the days of OSS, Emacspeak had a nice Emacs-interface to `aumix` and it is a piece of functionality that I have missed even more under ALSA, given that one can do many more sophisticated tweaks to one's sound-card. Tool `alsamixer` --- a full-screen terminal application is bewilderingly confusing (at least to me), and `amixer` though usable required me to go find out how it worked each time I needed to do something new. The final straw came last weekend when I tried to record some Emacspeak demos using `recordmydesktop` and needed to configure ALSA so that it would capture sound directly from the PCM output, rather than the microphone.

To cut a short story even shorter, I ended up writing an Emacs wrapper around `amixer` called --- well, you guessed it, `amixer`. The code is checked in as amixer.el. The Emacspeak keybinding `C-e (` formerly used to manipulate `aumix` is now ALSA-aware and will intelligently default to using the new `amixer` tool if `/usr/bin/amixer` is available.

## The Web The Way You Want

While working on miscellaneous Web related things including:

- Working on the W3C TAG in trying to understand how HTML TagSoup and well-formed markup might co-exist on the Web --- without the bad perennially driving out the good,
- Thinking about the Web Command Line, and placing various Web gadget/widget technologies in perspective,
- Building Emacs-G-Client --- an Emacs client for Google services,
- Connecting Emacs and Firefox via MozREPL to get the best of both worlds ,
- Refactoring some of the Web-related code in Emacspeak to better reflect the underlying ideas,
- Adding additional Web goodies to Emacspeak including Google Suggest in the Emacs minibuffer,
- And items too numerous to fit in this margin ...

I also wrote a draft chapter on specialized Web browsing. Given the set of things I have been working on, the end result is to point out that given the architecture and underlying design principles of the Web as embodied by HTTP, URIs and HTML, specialized Web browsing is in fact not so specialized after all.

## Google Suggest: Minibuffer Completion When Googling

Google Suggest has been available until now as a Firefox extension --- it displays a dynamically generated list of completions as one does Google searches in Firefox. The prefered way of Googling on the Emacspeak audio desktop --- using Emacspeak's Websearch facility available via `C-e ?` is now Google-Suggest enabled. This means that when doing Google searches via `C-e ?g`, you can type a partial query, and hit `TAB` to get a list of possible completions for the query.

## Emacspeak WebMarks: Online Bookmarks Using Google

Emacspeak module `emacspeak-webmarks` adds support for adding, viewing and finding Google Bookmarks. Google Bookmarks allows you to store your bookmarks at Google; this module adds support similar to that provided by Firefox Bookmarklets for Google Bookmarks implemented in JavaScript. Note that this module though relatively small was one of the motivators for the code refactoring described in Web Interaction in Emacspeak.

### Usage Tips

- To use Webmarks, you need to be signed into Google.
- Signing in to Google is easily done using the Webform provided as `xml-forms/glogin.html` in the Emacspeak distribution --- invoke it via key `C-e?/`.
- In addition, the very first time you use Google Bookmarks, add your first bookmark using form `xml-forms/bookmark-add.html`. Fill out that form, hit submit, and extract the value the `zx` parameter returned by the server.
- Use emacs Custom to save the value of the `zx` parameter as Emacs option `emacspeak-webmarks-key`.

## Web Interaction In Emacspeak

Users running out of SVN will have noticed that the emacspeak codebase has seen a significant number of updates over the last couple of weeks. During this time, I've refactored the Web interaction code in Emacspeak to meet the following goals:

- All Emacspeak Web smarts have now been re-factored to be independent of any given Web browser. In practice, this avoids code duplication between W3 and W3M support.
- The interface to XSLT has been significantly improved.
- When using W3, Emacspeak automatically builds a cache of CSS `classnames` and `ids` occuring on the page. These are then used to provide interactive completion when invoking commands `emacspeak-extract-by-id` (bound to `e i` in Web pages) and `emacspeak-we-extract-by-class` (bound to `e c` in Web pages).
- Module `emacspeak-we` holds all code related to editing Web pages before they are displayed.
- Module `emacspeak-webutils` holds all Web utility code.
- Atom and RSS feeds are now pulled using Emacs-22 built-in library `url` rather than via libxslt. This has the advantage that the feeds are pulled with any cookies the browser may have set during the session.
- All `url templates`, `search wizards` and related Web utilities should now be capable of working similarly under W3 and W3M.
- Module `emacspeak-moz` provides a basic level of integration with Firefox --- see my related blog post on FireBox.
- Module `emacspeak-w3m` still needs work to take advantage of all of these changes; I myself do not use W3M much, so those updates will happen as and when W3M users contribute the necessary time and patches.

## Emacspeak And Beautiful Code

In the fall of 2006, I was invited by O'Reilly Media to participate in an innovative book project called Beautiful Code. The project put together a set of chapters that focused on capturing the collected insight from creating real software. A particularly attractive aspect of this book was that it focused on code --- unlike many book projects in the field of software engineering, here the goal was to explicitly focus on real code and how it could be made beautiful.

The final book is now available in print. The chapter on Emacspeak is being published on this Web site under a Creative Common Licence --- this HTML version includes Chapter 31: Emacspeak --- The Complete Audio Desktop and the Afterword section from the book.

## Searching The Emacspeak Knowledge Base

Information about Emacspeak and its use is available from a collection of Web sites, and being able to restrict the search to these authoritative sources is a good way of quickly finding the right document, without being distracted by the numerous hits one finds when doing a search across the whole Web. You can now search the Emacspeak Knowledge Base by using search form `emacspeak-search.html`; access it via Emacspeak command `emacspeak-websearch` and specify `/`to bring up the list of available forms. This form is also the default search form on the Emacspeak Web site.

## HowTo: Implement Emacspeak Knowledge Base Search

Implementing the above using CSE is trivial --- all I needed to do was:

1. Checked in an HTML file into the Emacspeak repository at Knowledge Base.
2. Create a CSE that uses the above document.

## Emacs G-Client, Reader, And CSE: Searching Past Articles From Google Reader

So I use module `greader` (part of package G-Client to read a large number of ATOM and RSS feeds. I have long missed the ability to search for articles I remember having read a few weeks or months ago; though I typically find it with an appropriately phrased Google Search, I've always wanted to have the ability to restrict the search to the feeds I subscribe to --- this makes formulating the query much easier.

The advent of CSEs --- see my earlier blog post entitled On The Fly Custom Search combined with Google Reader's ability to export ones subscription list as an OPML file gives me exactly what I needed.

## HowTo: Enable Searching Of Past Articles From Google Reader

- Since you need to be signed in to access the subscription list, the CSE magic cannot directly retrieve your subscription list at present. as a consequence, you need to retrieve and save your list of feeds to a location that is publicly accessible. Feature Request: Would be nice if Reader did this automatically by talking to CSE on behalf of the signed-in user --- that would obviate the next manual step.
- Export your subscription list using command `greader-opml`. You'll need to do an `svn update` to get the above command; alternatively, sign in to Google and retrieve your subscription list.
- Finally, customize emacspeak option `emacspeak-url-template-reading-list-opml` to the location of the saved OPML file.

Now, you can use Emacspeak `url template` reader subscription search from the Emacspeak Web Command Line to search articles you remember having seen in your Google Reader. This is also an excellent means of finding articles of interest that one might have missed in the past. As an example, I recently became interested in Selenium --- an extremely powerful Web application testing framework. Finding articles from the past that I ought to have read but hadn't was a snap using the feature describe here.

## Making Search Fly: On-The-Fly Custom Search Engines

The Custom Search Engine team at Google recently released CSE On The Fly a truly amazing feature. Incidentally Google Custom Search is the same piece of magic that brought us Accessible Search last year.

So in the spirit of continuing to enhance the Web Command Line in Emacspeak for every smart Web tool that becomes available, I've checked in two new `url templates` that demonstrate how one can leverage this to be smart and selective about what one reads.

Searching Favorite Feeds
  So I read a lot of Blogs, my current Blog Reader is Google Reader via --- you guessed it -- Emacs module GReader (part of the Emacs G-Client package). But I often feel the need to search my favorite feeds. URL-template `Reader Subscriptions` lets you do this; what's more it's not specific to Google Reader. All you need do is to publish an OPML file listing your favorite feeds and customize Emacs variable `emacspeak-url-template-reading-list-opml` to point to that location.
Official GoogleBlog Search
  Google has a large number of Google-specific Blogs --- I usually read them through this aggregated feed: All GoogleBlog Stream Emacspeak wizard `Official GoogleBlog Search` builds a CSE from this feed to let you search articles from all of Google's blogs.

Eventually, I'll also add a meta search wizard that lets one construct any CSE on the fly --- with Lisp such meta-programming is a snap!

Later yesterday evening, I checked in a third `url-template` called On The Fly CSE that prompts for a search term and the URL for the feed of feeds that specifies the content to search.

## Emacs-G-Client: Uploading Photos To PicasaWeb

The SVN version of package Emacs-G-Client at g-client now includes a new module `gphoto.el` that can create albums and upload photos to Google's PicasaWeb site --- as an example, see my photo gallery. Emacspeak users are likely to find the RSS and ATOM feeds for photo albums more useful in general; package `gphoto` provides easy access to previewing these feeds as well as viewing/editting the metadata that goes along with the pictures. As an example of such a feed, here is Hubbell Labrador's Graduation album.

## Multilingual Dictionary Lookup Via Google

From the every useful Google tool deserves a Web Command-line equivalent ...

I just checked in an Emacspeak `url-template` for accessing multilingual dictionary lookup via Google. Invoke it like any other `url-template` using `C-e u` and type `mult tab`.Specify the word to look up, and the source-target language pair using two letter codes --- this is analogous to how the Emacspeak `Translation Via Google` tool works. And remember, if there is something you find yourself doing often on the Web, there is most likely an Emacspeak Web Command Line gadget for it --- well, at least that is true for the things I find myself doing often;-)

## FireBox: Put The Fox In The Box

I've finally found the right development environment for myself for writing and debugging Web Applications that use JavaScript to implement client-side interaction. It turns out that it wasn't just me who found the thought of programming inside the Web browser a painful experience --- pleasant though the final end-user interaction that those results deliver might be for the final user. I discovered MozRepl --- a read-eval-print loop for Firefox. MozRepl is a Firefox extension that allows you to open a connection to a running Firefox session and gain access to a JavaScript interpreter context that can access all aspects of the Firefox runtime.

This is quite neat, I can now use the power of Emacs to write and debug end-user JavaScript applications. But wait, there is more. So in general, as someone who doesn't need to suffer from the hit on cycles and memory that running an X environment involves, I usually dont start `GDM` --- the graphical desktop --- on my Linux box. Believe me, running just at the console, especially with the LCD turned off makes my laptop run a lot longer. So challenge: How do you take the fox's head off Firefox? How do you run a headless Firefox?

Turns out that the original X Windows developers didn't always have access to all the displays that they were developing X applications for --- so they created `XVFB` --- the X Virtual Frame Buffer server. Like all good things in the Open Source world, XVFB continues to survive --- even though today, X developers hardly if ever resort to XVFB. But in the fine UNIX tradition of <quote>Get out of my way or I'll turn you into a shell script</quote> XVFB also turns out to be just what I needed in order to run FireFox as a headless application.

So in summary: I'm typing this blog on the shuttle bus ridinghome, with the monitor turned off, and Firefox running headless as I debug some of the code I've been writing. If you want to put the fox's head in a box yourself, here is a pointer to FireBox -- share and enjoy!

## An Essay On Eyes-Free Computing

I just posted an essay on eyes-free computing to my MathZomeblog. This essay highlights the relevance of ZomeTool in teaching mathematical concepts to students who are visually impaired. More generally, it describes my experiences as a mathematician who cannot see. I'm posting the abstract here; the complete essay can be found on my Web site.

The experiences described in this essay have influenced the software I have built and use on a daily basis; it should be of interest to:

- Emacspeak users wishing to understand why things look like the way they do in Emacspeak.
- Students with visual impairments who are entering the field of mathematics.
- Teachers working with visually impaired students.
- And the generally curious mathematician who wishes to view the world from a different perspective.

### Abstract

This essay outlines some of my experiences as a mathematician who cannot see. Note that I transitioned to being a Computer Scientist during Graduate School. However I strongly believe in the edict Once a mathematician, always a mathematician! — my training in mathematics continues to influence the way I think.

I've been unable to see since the age of 14, which means that I've studied and practiced mathematics predominantly in an eyes-free environment. This essay is my first conscious attempt at asking the question What is involved in doing mathematics when you cannot see? I hope that some of the experiences outlined here will prove insightful to mathematicians at large. At its heart, mathematics is about understanding the underlying structure inherent in a given area of interest — and where no such structure exists — to define the minimal structure that is needed to make forward progress.

The general perception that mathematics might be hard to do in an eyes-free environment probably traces itself to the common view of mathematics as a field where one performs copious calculations on paper. I'll illustrate some of the habits and abilities one evolves over time to compensate for the lack of ready access to scratch memory provided by pencil and paper when working in an eyes-free environment. In this essay, I hope to demonstrate that mathematics in its essence is something far bigger. By being bigger than calculations on paper, not being able to see rarely if ever proves an obstacle when it comes to doing mathematics; the challenges one needs to overcome are primarily centered around gaining access to mathematical material, and communicating ones insights with fellow mathematicians. Thus, a large portion of this essay focuses on solutions to the challenges inherent in mathematical communication.

## Web 2.0 And The Emacspeak Audio Webtop

Blogging while at WWW 2007. I attended the W3C AC meeting the first two days of the week. The highlight for me from the AC (Advisory Committee meeting was a panel consisting of TimBL and Tim OReilly at the end of the day yesterday. It was fun to hear Tim OReilly define Web-2.0 --- he is credited with originally coining the term, but in the last year, Web 2.0 has often been lightly equated to dynamic Web applications that use JavaScript to the extent that many assume that anything that doesn't use JavaScript is not Web-2.0!

The gist of Tim O's definition of Web-2.0 was to point out that once the Web had gained sufficient coverage and scale, it became possible to build application services on this Web that drew their value from aggregating the data on the Web; his examples ranged from Google to Amazon. His comments were insightful --- my own view now is that Web-2.0 should have been called Web^2 i.e. this current revolution is about applying the power of the Web to itself.

The other amusing piece while running around at the conference and observing what everyone is working on is to realize that now that Web Gadgets and the like are popular, it's now considered a fine idea to write light-weight site-specific tools. Notice that Emacspeak has had this since the late 90's in the form of first the websearch module, to be later joined by url-templates. I believe these innovations arrived earlier on the Emacspeak Webtop as compared to the rest of the Web for the following reasons:

- Emacspeak relied on Emacs/W3 for Web functionality,and when that browser stopped being maintained, there was a strong need to develop Web tools in the context of Emacspeak.
- The visual Web was getting too complex for use via speech output, and given the flexibility of the Emacs environment, and the arrival of XSLT in 1999, things were well set up to build a powerful set of Web access wizards.
- Task-oriented Web tools in Emacspeak led to the conceptual Web Command Line in Emacspeak at a time when command-line interfaces were considered passe'.

Incidentally when I showed others working in the field of accessibility these Emacspeak tools during their early days, they were promptly dismissed as site-specific hacks that wouldn't scale in the face of generic screenreaders that would handle every web page. With the visual Web getting too busy for everyone mainstream users now have access to productivity solutions such as Apple's Dashboard Widgets, IGoogle modules that can be placed on a Web page or the desktop, and other comparable tools. It will be interesting to see how much longer blind users saddled with commercial screenreaders will have to wait before seeing similar tools emerge in their world --- just remember, when that does arrive, Emacspeak had them in 2000!

## See You At CSUN 2007

After a gap of 7 years, I will once again attend CSUN in LA this year. This will also be Bubbles' first CSUN --- I attended CSUN 6 years in a row with Aster between 1994 and 1999. Anyway, if you're an Emacspeak user and are coming to CSUN this year, look for me at the Google booth. This is also Google's first year at CSUN; I will be there with other Googlers working on accessibility. I arrive Wed morning and leave early Friday morning --- look forward to seeing you there.

## An Emacs Client For Google Services

## 1 An Emacs Interface To Google Services

Google offers a number of services using a Google account. Many of these services also expose a Web API. this package provides a set of Emacs modules for accessing these services from inside Emacs. These modules are designed with an Emacs-centric, rather than a Web-browser centered view of the world. Where necessary Emacs package `browse-url` is used to invoke the Web browser of choice.

The current distribution can be downloaded from Google Code Hosting and the source code is available via Subversion. Note that this is still work in progress. I'm releasing it as part of the Emacspeak project since I believe the package already has sufficiently useful functionality for users who spend a large amount of their time inside Emacs. There is no dependency on Emacspeak, and all clients provided here can be used without Emacspeak loaded.

### 1.1 Installation

These are needed only if installing package `g-client` stand-alone, i.e. outside of Emacspeak.

- Unpack the tar archive and place the resulting `g-client` directory on your emacs `load-path`.
- Type `make` to compile the code.
- In your .emacs, add `(load-library "g")` to set it up.

### 1.2 How It Works

Clients are implemented using Google APIs based on Atom Publishing Protocol APP and Google Data APIs (GData). We use `curl` to retrieve content via HTTPS and `xsltproc` to transform the retrieved content to browsable HTML.

Clients sign you in the first time you invoke commands that require authentication. Once signed in, the session cookie is cached for future use. Session cookies presently expire in 30 minutes, and clients check forexpired cookies when authentication is needed. If the cookie has expired, clients retrieve a fresh cookie using the authentication credentials provided earlier. Note that authorization tokens etc are specific to a given service.

### 1.3 Top-level Customizations

All clients in this package use Emacs' `customize` interface to set user preferences. The most commonly used ones are enumerated below.

- `g-user-email` Default email-id to use. Individual clients typically override this via user option `<clientname>-user-email`.
- `g-html-handler` Name of function that handles HTML content.

### 1.4 Google Blogger gblogger

This client implements posting, editting and deleting of blog entries using the new Blogger API --- it replaces the now obsolete atom-blogger that implemented similar functionality using the old Blogger API. It uses value of customization option `g-user-email` by default; this can be overridden via option `gblogger-user-email`. See Blogger GData API for the underlying APIs used. For editing posts, I recommend installing nxml-mode.

- Browse Command `gblogger-blog` brings up the list of blogs owned by the currently authenticated user.
- Posting Command `gblogger-new-entry` takes a post URL and sets up a special buffer where you can compose your article. the post url is obtained from the feed of blogs above, use the post link for the blog to which you wish to post.
- Browsing Command `gblogger-atom-display` displays the atom feed for a specified blog as a browsable HTML page. In addition to reading your blog, this helps you find the edit url for individual posts.
- Editting Command `gblogger-edit-entry` takes the edit url of a previously posted entry. It retrieves the entry, and sets up a special composition buffer where you can edit the entry.
- Submitting The special composition buffer created by commands `gblogger-new-entry` and `gblogger-edit-entry` provide a special command `gblogger-publish` (bound to `C-c C-c`) that submits the entry to blogger.
- Deleting Command `gblogger-delete-entry` deletes an entry specified by its edit url.

### 1.5 Google Calendar gcal

This client can be used to view, add or delete events from the Google Calendar for the authenticated user. It uses value of customization option `g-user-email` by default; this can be overridden via option `gcal-user-email`. Commands that display calendar items optionally accept the feed url of the calendar to view; this can be used to view calendars to which the authenticated user has read access. See GData Calendar API for the underlying APIs used.

- View Command `gcal-calendar-agenda` displays the default calendar for the authenticated user. A prefix arg prompts for the calendar to display. This command is best used from inside the Emacs calendar; in this case, it uses the date under point when showing the agenda.
- Add Command `gcal-add-event` prompts for event details and adds it to the calendar.
- Accept Command `gcal-accept-event` accepts an event. Event is specified using the edit url of the event.
- Delete Command `gcal-delete-event` deletes an event. Event is specified using the edit url of the event.

### 1.6 Google Reader greader

This client allows the authenticated user to read, browse and subscribe/unsubscribe to feeds. It uses value of customization option `g-user-email` by default; this can be overridden via option `g-user-email`.

- Reading Command `greader-reading-list` displays the reading list (river of news).
- Browsing Command `greader-feed-list` displays a browsable Web page with pointers to subscribed feeds.
- Finding Command `greader-find-feeds` searches for matching feeds to subscribe.
- Subscribing Commands `greader-subscribe-feed` and `greader-unsubscribe-feed` are used to subscribe and unsubscribe.
- Labeling Command `greader-star` and `greader-add-label` are used to label articles.
- Reading Starred articles can be read by providing a prefix argument to command `greader-reading-list`. Thus, C-u M-x greader-reading-list will prompt for the specific set of articles to retrieve.

## Emacspeak Downloads On GoogleCode

I've now made all Emacspeak releases available from the download area on Googlecode. Going forward, all Emacspeak releases will be made at the GoogleCode site --- not SourceForge. This is because uploading code to GoogleCode is significantly easier than making releases on SourceForge.

But even more importantly, once uploaded, grabbing a release from GoogleCode is significantly easier than on SourceForge's release mechanisms. You can always find a link to the latest releases from Emacspeak on GoogleCode by starting from the Emacspeak GoogleCode page. Follow the link labeled Featured Downloads to download the newest release. I've also made all past releases from the download area --- follow the link labeled downloads on the Emacspeak GoogleCode page.

Here is a brief summary of why I chose to start making releases on GoogleCode, it can be viewed as a short summary of the positives in making the switch.

- GoogleCode makes it possible to create download URLs that can be bookmarked. No more clicking through multiple pages before getting to the file you want, you can simply point `wget`, `curl` or your favorite download tool at a meaningful URL. For instance, here is a pointer to Emacspeak 25 release.
- The above is more than a convenience --- it's in line with good Web architecture. I've been looking for an alternative to SourceForge ever since that site decided to turn meaningful download URLs from the past into obfuscated pointers into their content management system; this left me with a feeling of having created Open Source Software only to have it locked away in someone else's vault with no easy mechanism for end-users to retrieve what had been released as free software.

Share And Enjoy --- and let's hope we never have download sites that say Glad to be of service as they close behind you with a sigh of a job well done.

## IBM Software TTS On Ubuntu 6

I had earlier reported the IBM TTS engine segfaulting on my home Ubuntu 6 machine; I'm still to fix that problem. Surprizingly though, I tried it on a different Ubuntu 6 machine, and there, installing

          sudo apt-get install libstdc++2.10-glibc2.2

on top of the regular Ubuntu install was enough to get the TTS working. The segfault on my home machine occurs inside libc, and as best I can tell the two machines have identical libc installs. So on the positive front, it's only my home machine that appears broken; on the negative side, the fact that the breakage is hard to explain and hence fix doesn't inspire confidence in upgrading. Others have reported not having any problems on Edgy -- so the problem is hopefully transitory.

## Web Command Line Tool For Google Patent Search

From the every new Google search tool gets a corresponding Emacspeak wizard dept:

Google just introduced Patent Search an easy to use search interface for US patents. In the spirit of the Web Command Line, Emacspeak now sports a Patent Search From Google smart URL like other smart URLs on the Emacspeak Audio Desktop, this places executing patent searches just a few keystrokes away. To use this new wizard, do the following:

- Update your working copy of Emacspeak from SVN. The patent search wizard will be part of the next official Emacspeak release slated for May 2007.
- Invoke the Smart URL tool by pressing `C-e u`
- Type the first few characters of the phrase `patent search from Google` and hit `tab` to complete the name of the smart URL.
- Hit enter, specify what you're searching for and hit enter again.

happy inventing ---

## Emacspeak 25.0 (ActiveDog) Unleashed

I released Emacspeak 25.0 (ActiveDog) yesterday. Here are the release notes.

While trying to release it on Sourceforge I ran into a couple of show-stoppers --- first off the SourceForge download mechanism has changed yet again and it's now gotten sufficiently convoluted that software released via SourceForge's file release system is becoming well-nigh impossible to download except for the most motivated user. Worse, as I released the file, upload services on SourceForge hung, with a consequence that it created a 0 sized `emacspeak-25.tar.bz2` file --- the SourceForge mechanism made it well-nigh impossible to clean up the 0-sized file.

Given this mess, I decided to keep things simple by placing the release on the Emacspeak site directly -- this suffers from the disadvantage of the release not getting mirrored on the various Sourceforge download archives; it has the advantage of allowing users to grab the release with one click.

The other thing to note about this release is that there are no RPMs built --- a first in 7 years. I've now switched to Ubuntu on my home machine and dont have the ability to build RPMs so I'll leave this to individual distributions. I've also not built Debian packages this time around, mostly because I've not gotten around to understanding Debian's packaging system sufficiently well to do this. Moreover I prefer minimalistic packaging solutions --- and in general though Debian's packaging is nice, it still feels a little too heavy-weight for something like the Emacspeak source tarball which needs a simple `make; sudo make install` to get set up. So for now, I'll rely on folks like Jim Van Zandt to build downstream Debian packages for incorporating with the various distributions like Debian and Ubuntu --- this way, packages can be built to match particular distributions.

## Emacspeak Smart URL For Google Code Search

Every useful Web tool deserves a Web short-cut. Google just announced a new service called Code Searchthat lets you search the codebases of Open Source projects. It's a great way of finding source code relevant to ones programming projects.

I just checked in a corresponding `URL Template` --- as a reminder, `url templates` in Emacspeak aresmart URLs that provide web short-cuts to create a conceptual Smart Web Command Line. To use:

- Invoke the `url template`tool via the default key-binding `C-e u`.
- Select the `Code Search Via Google` tool by typing `cod` and pressing the `tab` key.
- Specify the search query --- see the Google Code Search help instructions for the types of queries that are allowed.

## Using Helix Player From Emacspeak

In the spirit of You can never have sufficiently many media players, I now have Helix Player working under Emacspeak i.e., I can now run Helix Player without having to start up X. This is useful because there are still media streams on the Web that sometimes fail with `mplayer`, and from the minimaltesting I've done so far, Helix Player is successful in those cases.

### What Is It?

HelixPlayer --- installable on modern Linux distributions as `hxplay` from package `HelixPlayer` is the community-supported version ofRealPlayer 10. The well-distributed and documented client, `hxplay` is capable of playing a wide variety of audio and video formats over HTTP and RTSP/RTP, and specifically, can handle RealPlayer10 formats which includes support for 5.1 audio.

A lesser known set of tools available from Helix --- Helix DNA Client is a bare-bones UI-less player which can be used effectively at the shell. You can download pre-built binaries for your flavor of Linux (GCC3.2 or later vs GCC 2.95 based systems) note that these are nightly builds. You can also download a source zip archive. Note that all of these requires you to accept a End Users License Agreement (`EULA`) before being taken to the download link.

The links on the page above can be confusing; Here are pointers to the specific packages you need to grab if you want a player that has all of the functionality described above.

Binary
  Sep 26, 2006 build for Linux GCC 3.2
Sources
  Source archive from September 27, 2006

### Using The Binary Distribution

Here is what I did you set up the binary distribution on my Ubuntu 6.0.6 (Dapper) machine

- Unpacked binary package under `/usr/lib`.
- Created a symlink `/usr/lib/splay` to point to the directory created by unpacking the binary package.
- Created the following shell script `/usr/bin/hsplay` to launch the player:

            #!/bin/sh
            #Use Simple Helix Player:
            #
            SPLAY_LIB=/usr/lib/splay
            export HELIX_LIBS=$SPLAY_LIB
            exec /usr/bin/aoss $SPLAY_LIB/splay -iss -s "$@"

- The above script assumes you have the `alsa-oss` package nstalled; you will need this to have Helix Player use ALSA --- something that is essential if you want to be able to use your sound card with other applications while playing media streams.

With this setup, you can launch one or more media streams (both local, as well as remote HTTP/RTSP/RTP streams) from a shell. This player successfully plays the `BBC Radio4 LW` stream, something `mplayer` fails to play on my Ubuntu box.

## Emacspeak, Ubuntu And Software Dectalk

On the positive side with respect to software synthesis, the Software Dectalk does work out of the box on Ubuntu --- out of the box that is if you first install `alsa-oss` the ALSA->OSS compatibility layer. I've updated the Emacspeak speech server for Software Dectalk to use `alsa-oss` where available; performance is not as responsive as the Emacspeak Viavoice server using the native ALSA APIs, but it's a good backup option.

## Emacspeak 24 On Ubuntu 6

I upgraded my home FC3 machine to Ubuntu 6.0.6 (Dapper) over the weekend. Here is a short summary for things to watch out for as an emacspeak user.

## The Good, The Bad, And The Painful

Good
  One of my friends helped with the install and it is remarkably quick when everything works (in my case the Ubuntu LTS 6.0.6 installer had trouble with the NVidea display card and came up correctly at the third attempt).
Bad
  A one CD install is nice -- but after it you have remarkably little installed from the perspective of an emacspeak user. You end up with a very nice GUI but very little else --- the reasoning being that the average user wont need much more, and the savvy user can always run `apt-get`.
Bad
  Worse, Ubuntu does not install `openssh-server` --- it limits itself to installing `openssh-client`. This means that you cannot bootstrap yourself by logging in from another machine until you install `openssh-server` off the network. If there was one thing I would ask the Ubuntu maintainers, it would be to rectify this situation.
Painful
  In my case, the `apt` suite of tools appeared to have a problem --- they died saying `/var/lib/dpkg/available: no such file or directory`. Googling showed this to be a known problem with `apt` and the fix is to run `dselect update` -- but if you're new to Debian/ubuntu, this is less than obvious.
Good
  Once you overcome the above, `apt-get` got me emacspeak-17.0 which was sufficient to let me bootstrap the rest of the process on my own using my trusted Dectalk Express to produce speech.
Painful
  Note that you should install `tcl8.3` and`tclx8.3` --- rather than the newest (8.4) versions of these packages. This is because as of 8.4, the maintainers of those packages no longer build a stand-alone `tcl` (extended TCL) shell. This is something that will have to be handled by Emacspeak in the future.
Good
  I was able to get everything I needed (and more) installed using a combination of `apt-get` and `aptitude`.
Bad
  The IBM TTS engine no longer works --- under FC3 and friends, you needed to install package `libstdc++-compat` toget it to work. Well, there is no corresponding package for Ubuntu/Debian from what I could find out, and pulling in the RPM for `libstdc++-compat`, converting it via `alien` and installing the resultproduces a segfault when you run the TTS engine.
Bad
  For the same reason, the old command-line `trplayer` will also not work on Ubuntu 6.0. This is not as painful --- since mplayer works --- though I had to build `mplayer` from source. It would be nice to create a command-line player on top of the HelixPlayer code base. At present, the missing `trplayer` means that the `etc/rivo.pl` provided by emacspeak no longer works. You can use `mplayer` to convert `realaudio` to mp3; however `mplayer`does not have a command-line option to specify the duration of playback, something that script `etc/rivo.pl` needs.

## Google Archive News Search

To mark the arrival of Google News Archive search, I checked in a Archive News Search `url-template` yesterday morning. To use it, hit `C-e u` followed by `arc tab` and specify your search term.

The above is checked into the SVN repository at Emacspeak GoogleCode.

## Update: Emacspeak On Google Code Hosting

The initial experiment of moving emacspeak development to Subversion at Google Code Hosting has been largely successful. After a few bumps along the road, mostly a consequence of my being new to SVN, things are looking good, and I have stopped updating the CVS repository on SourceForge.

Some additional goodies as a consequence of the move to SVN:

- SVN Tags contains snapshots of prior releases.
- Future releases will come with an SVN Revision number that allows one to reliably recreate a released version.

## Emacspeak Codebase Via Subversion From GoogleCode

I've checked in the Emacspeak codebase into the Subversion repository provided by Google Project Hosting . The project page is Emacspeak at GoogleCode. You can find Emacspeak --- complete with its code history going back to the point where I started using CVS at Emacspeak SVN Repository.

For now, the Emacspeak Web site will continue to live at Sourceforge; The Emacspeak mailing list will continue to live at Vassar as before. To checkout the code from SVN, follow the instructions on Emacspeak SVN. If you run into any hitches in checking out the code, please report it on the Emacspeak mailing list. Note that you can anonymous checkout the code from the above location entirely from the shell command-line without ever having to point a browser at anything.

Emacspeak users presently running out of SourceForge CVS might want to do an SVN checkout in a separate directory and make sure things work, in preparation for a permanent switch-over to svn. Here are the minimal steps you need to perform:

- `svn checkout http://emacspeak.googlecode.com/svn/trunk/ emacspeak`
- The above will create a directory called `emacspeak` with the code under it; obviously, you should do this somewhere different from where you have your current copy of emacspeak.
- For now, I recommend renaming the directory created in the above step to `svn-emacspeak` so that you can easily tell which snapshot you're looking at.

Note that reading these is not a replacement for learning about SVN --- there is an excellent on-line book available at SVN Manual.

## Zipping Through Web Pages

## Zipping Through Web Pages With Emacspeak/W3

I just added an experimental zip through Web pages shortcut to `emacspeak-w3`. The command is called `emacspeak-w3-speak-next-block` and is bound to `z` in all W3 buffers. It is useful for quickly moving through Web pages that have logically separate content units in separate blocks where a block is one of:

- HTML `div`.
- HTML tables.
- HTML `p` elements.

In general this provides an effective means of skimming many large Web pages.

## Summary Of Emacspeak Features Compared To Other Alternatives

## Introduction

I've received a number of queries asking about the differences between Emacspeak and Speechdel ---especially given some of the somewhat confusing assertions made in recent Speechdel release announcements. I'm posting this article in the hope of clearing up some of this confusion.

## 1 Emacspeak And Speechdel -*- mode:org -*-

### 1.1 Background

Emacspeak speech-enables Emacs by advising core emacs functionality. Speech services are provided by a simple Emacspeak speech-server. Additionally, Emacspeak implements speech-extensions for popular emacs modules --- see the speech-enabled applications list.

Emacspeak was first released in 1995, and then (as now), there was limited speech access to the Linux GUI. Therefore, to be useful as a complete access solution, Emacspeak has always needed to enable the user to do everything from within Emacs, not just regular editing operations. As a case in point, emacspeak users are probably one of the last remaining communities that use Emacs for browsing the Web.

### 1.2 Speech Dispatcher (SpeechD)

The idea of SpeechD --- peech Dispatcher as an intermediate layer between speech clients and TTS engines was first floated sometime in the late 90's. Such a common layer is a laudible goal but is something that takes time and effort to get right. Additionally, you have the challenge of geting existing software e.g., emacspeak, to abandon their own speech abstraction and re-implement against a supposedly more generic, but completely untested and untried intermediate layer.

The developers of SpeechD initially incorporated some of the Emacspeak code into an Emacs wrapper (speechdel) that called SpeechD, but later decided to go their own way -- and present speechdel is the result.

Like Emacspeak, speechdel uses Emacs Lisp's advice facility to add spoken feedback to core editing commands; speech output is produced by calling out to speech-dispatcher.

The summary of feature differences between Emacspeak and speechdel in the next section is from examining the speechdel code-base; I have not run speechdel since its dependency chain resulting from speechd was difficult to resolve on my FC3 64bit machine.

### 1.3 Emacspeak Features Not Found In SpeechDel

1. Emacspeak implements Aural CSS ACSS, and uses it to provides the aural analog of `font-lock`.
2. Emacspeak provides pronunciation dictionaries. Pronunciations can be defined on a per-mode, per-buffer or per-directory basis. Directory and mode specific pronunciations are persisted across sessions. This allows Emacspeak to leverage Emacs' intelligence about the semantics of a given application; thus, you can have it say "p arrow x" for "p->x" when editing C code. Per-directory pronunciations are useful for reading electronic books. Per-buffer pronunciations are useful for succinctly speaking long lines of shell output e.g. when compiling complex software.
3. By advising core Emacs functionality, Emacs modes work out of the box with Emacspeak. But in most cases, Emacspeak goes one step further by providing light-weight speech-modules that specialize spoken output for a given mode. As an example, advising next-line to speak the current line is sufficient to use `dired-mode` --- but having to listen to the entire line of dired output is not a pleasant experience. The dired-specific module in Emacspeak advises all interactive dired commands to speak the "right" information. As an another example, GUD interaction automatically speaks the line of source-code without leaving the Gud buffer.
4. Emacspeak comes with many "Emacs Applets" for performing tasks that most users would perform outside of Emacs. Examples include playing CDs, playing multimedia streams etc. Fortunately, I have not had to write too many of these since there are always Emacs users other than myself who also create such Emacs applications --- so where Emacs applications already exist, I merely speech-enable them with a small set of advice definitions, and in some cases add a few additional interactive commands.
5. Emacs applications are plentiful for most tasks; one exception is the Web. Since emacs/w3 development was abandoned sometime around 1998, I have added significant Web interaction functionality to Emacspeak using Emacs/W3 as the basis. Today, a lot of this has also been ported to Emacs/W3M thanks to other enthusiasts on the Emacspeak mailing list. Examples include:
   1. WebSearch module --- prompts for query and processes response to focus on the results.
   2. XSLT pre-processing: Allows pre-processing of complex pages before rendering via W3. Used to enable smart screen-scrapers using XPath.
   3. URL-Tempaltes: Originally motivated by `webjump.el`, this provides url templates that enable easy access to a variety of Web tasks rangig from looking up flight times to listening to your favorite NPR or BBc show. Think early cut at a "Web Command Line in the minibuffer".
6. Customization via Custom, including additional keymaps. Comes with additional keymap files for the Linux console to enable `hyper`, `super`, and `alt` prefix keymaps.
7. Module emacspeak-wizards iplements a large collection of Emacs wizards that enable common tasks that you would otherwise perform at the shell e.g., checking display status on a laptop. The additional prefix keymaps come in handy!

8)Finally, note that all modules (except the core) are loaded on demand.All code is compiled with `byte-compile-dynamic` set to =T= and individual application-specific modules are kept completely independent of one another. Given the size of the Emacspeak codebase, this is a pre-requisite for both efficiency and developer sanity.

## Emacspeak And Accessible Search Via Google

Google has released an early experiment that favours easy to read Web content --- checkout the relevant Blog post here. Emacspeak has always had a set of Google Websearch tools --- and this set has now been enhanced with a shortcut to Accessible Search. Below, I'll summarize the set of Google Websearch tools in Emacspeak.

All Emacspeak Websearch tools are reached via the key-sequence `C-e?`. Specific search tools are selected by single-letter keystrokes following `C-e?` --- I'll enumerate some of these below.

i
  Accessible Search --- Google Web Search that favors accessible content.
g
  Vanila Google Search.
space
  Google I'm Feeling Lucky --- takes you directly to the first search hit.
n
  Google News Search.
e
  EmapSpeak Via Google Maps.
u
  Google Usenet Search.

Note that in addition, module `emacspeak-url-template` provides a number of Google tools as smart URLs.

## ALSA And Emacspeak: Closing The Legacy Loop With ALSA-OSS

And now, with ALSA working well with software TTS and cooperating with ALSA_aware streaming applications such as `mplayer` it's time to close the legacy loop for those few applications that still have the old `OSS` API hard-wired.

One such useful application is `trplayer` --- the command-line real player that has not been updated inover 4 years. For the most part, the functionality provided by `trplayer` is subsumed by the newer --- and actively maintained --- `mplayer` but it's still useful to have `trplayer` for times when `mplayer` hits gliches with slow-responding RTSP streams.

The ALSA way of handling such legacy applications is through the ALSA OSS emulation layer; Emacspeak now contains a script `etc/atrplayer` that invokes `trplayer` via `aoss`. Incidentally for the more observant Emacspeak user running out of CVS, script `atrplayer` is not new; it has been around for about a year, but until now it used command `vsound` to stream the converted audio to command `aplay`. I needed to do this until ALSA 1.0.11 since `trplayer` used to fail sporadically if run through the `AOSS` emulation layer. But those problems now seem to be in the past with the upgrade to ALSA 1.0.11. As usual with cutting edge technology like ALSA, your mileage with all of this will vary; so let me end with the usual disclaimer --- if it breaks, you get to keep both pieces.

## SpeakFreely, Software TTS And ALSA

In ALSA and ASYM I mentioned that `speakfreely` appeared to have stopped working. As it turns out, this had nothing to do with the switch to ASYM. I believe that in the past I had run speakfreely by first killing software TTS --- since by default `speakfreely` uses OSS.

Getting `speakfreely` working with ALSA without losing software TTS required the following steps;

1. Retrieve the latest tarball `speak_freely-7.6a.tar.gz`
2. Uncomment the `ALSA` specific line in its`Makefile`
3. In file `audio_alsa.c`, change the default audio device from `plughw:0,0` to `default`. Without this change, speakfreely will try to access the sound card directly; setting it to `default` on line 41:

             char *devAudioOutput = "default";

   matches things up with the `pcm.default` that was configured in the `.asoundrc`.

With this, you can now talk using `speakfreely` and continue to use software TTS.

## Emacspeak, TTS, Alsa And ASYM

This is a continuation of the earlier thread about using ALSA for software TTS using DMix --- see ASoundrc And Emacspeak.

I've now updated the CVS version of `ASoundRC` to use the `ASYM` plugin for the default ALSA device. The `ASYM` plugin allows you to configure both the playback and capture device, which removes the annoyance of having to specify an ALSA device when calling `arecord` --- as used to be the case when using `DMIX` in the `pcm.default` device.

Possible Caveats: I am having trouble getting `speakfreely` to work reliably --- I've used it with ALSA in the past --- though I'm not sure if the `ASYM` plugin is the culprit.

## ASoundrc Parameters For Reliably Using ALSA Powered Software TTS

Advanced Linux Sound Architecture ALSA is a boon for software TTS users --- you can now use your soundcard to produce spoken output while not losing audio output from other applications such as music players and streaming radio stations.

Emacspeak implements an ALSA-enabled TTS server for the IBM ViaVoice engine --- using this server effectively requires appropriately tuning the parameters in the user's `asoundrc` file to:

- Enable the `DMix` plugin to enable software mixing of multiple channels of audio.
- To configure the various parameters ALSA itself uses.

Depending on how well your sound-card is supported by ALSA, the above can be either trivially simple or a tedious process of trial and error. I'm writing this up to:

- Collect a list of sound cards on which the `asoundrc` provided with Emacspeak works as expected.
- In the hope that the wider ALSA community discovers and helps flesh out this material; my hope is that the ALSA community has more insight into how these settings work.

For the above, works effectively means the following:

- The TTS engine speaks without perceptible stuttering or other audio artifacts.
- The engine is responsive with respect to starting and stopping speech; especially when typing fast at high speech rates.
- The TTS engine does not interfere with other alsa-enabled applications, e.g. `mplayer`.

At the end of this entry, you can find the relevant section from the `asoundrc` file from the Emacspeak distribution, with comments indicating which sound cards perform well. An example of a card that does not work well with these settings is the Audigy-LS from Creative; the TTS engine works on that card, but performs degrades:

- mplayer cannot use the audio device; (aplay and mpg321 are able to share the card with the TTS engine.)
- Speech does not stop immediately as on the soundcards enumerated in the `asoundrc` file.

## Listening To The Web Through A Mobile Lens

The similarities between Web access issues faced by mobile users and those confronting eyes-free Web browsing are striking, and these similarities have often been used to advocate the creation of well-structured, accessible Web content. As an example of mobile-friendly content being a blessing for eyes-free spoken access to WebFormation, Emacspeak provides a mobile lens via the Google Mobile transcoder.

Here are a few convenient means of using the above within the Emacspeak Audio Desktop:

- While browsing the Web using `w3`, press `t` on a link (command: `emacspeak-w3-transcode-via-google`) to view that link through the mobile transcoder.
- Note that all links in the resulting mobile view automatically go through the transcoder.
- To undo the effect of automatically viewing links in the mobile view through the transcoder, use `t` with a interactive prefix argument i.e., press `C-u t` to follow a link to view it in its original form.
- Additionally, I bind command `emacspeak-wizards-google-transcode` to a convenient key so that I can launch Web sites using the mobile view.

I use this tool on a regular basis while commuting to work to browse mainstream news sites, it provides speech-friendly content that has the added benefit of downloading fast over a wireless link --- after all, this is Mobile content.

## W3: Minor Patch To Handle Content-Type application/xhtml+xml

Here is a minor patch to w3.el to allow it to handle content-type `application/xhtml+xml`. For all practical purposes (at least as far as W3 is concerned), this can be handled by the html parser/renderer; however since that content-type did not exist at the time W3 was written, it offers to download/save documents of that type. The attached patch fixes this, and also adds a fix to a minor irritant with decoding of multimedia attachments.

## Emacspeak: Connecting Lynx And W3

Emacs/W3 is still the best Web page rendering option inside Emacspeak given the ability to apply XSL transforms, as well as obtaining aural styling via ACSS. However W3's url handling layer often breaks when faced with multiple redirects, especially when some of these happen through the `Host:` HTTP header. Additionally, `HTTPS` authentication sometimes fails mysteriously in the presence of redirects.

In many of these cases, `lynx` happily fetches the pages correctly; however you're then stuck using a fairly weak auditory interface in that Emacspeak degrades to being aterminal level screenreader.

An effective solution to this problem is to use `lynx` within an Emacs terminal, and after finding the content that is worth reading, handing off that content to Emacs/W3. The next few paragraphs show how.

#### The `lynx-site.cfg` File

This is where you add site-specific configurations. Here are the lines I have in my `lynx-site.cfg` tointegrate `lynx` and Emacs. Before you use any of this, make sure you have executed `M-x server-start` in your running Emacs, and make sure that all is well by experimenting with `emacsclient` to ensure that external programs can hand-off editting tasks to the currently running Emacs.

          #site defaults
          #for bookshare:
          DOWNLOADER:BKS Unpack:bks.pl  %s %s:TRUE
          PRINTER:Edit:emacsclient %s:TRUE
          KEYMAP:???:EDITTEXTAREA	# use external editor to edit a form
          textarea      PRETTYSRC:TRUE
          SOURCE_CACHE:MEMORY
          SAVE_SPACE:~/.wget/
          BOLD_HEADERS:TRUE
          PRINTER:W3:emacsclient -e '(w3-open-local
          "%s")':TRUE

Below, I'll describe what each of the above lines do:

- `DOWNLOADER:BKS Unpack:bks.pl %s %s:TRUE`
  The above line creates an additional item in the download menu that invokes the BookShare unpacker. Script `bks-unpack.pl` invokes the BookShare unpacktool with the appropriate options.
- `PRINTER:Edit:emacsclient %s:TRUE`
  This creates an Edit item in the print menu. Invoking this menu item causes the current page to be handed off to Emacs for editting. If you want to edit the source, first switch to source view by hitting `\` before invoking print.
- `KEYMAP:???:EDITTEXTAREA # use external editor to edit a form textarea`
  This sets lynx up so that when editting a multiline textarea, you can hand off the editting job to Emacs. This is particularly useful for editting Wiki pages. Replace the `??` with the desired key sequence.
- `PRETTYSRC:TRUE
  SOURCE_CACHE:MEMORY`
  The above two settings make the edit source functionality more pleasant to use.
- `PRINTER:W3:emacsclient -e '(w3-open-local "%s")':TRUE`
  The above creates a W3 menu item in the print menu. Invoking this causes Emacs/W3 to display the current page --- again switch to `source view` before invoking this so that Emacs/W3 gets handed the HTML markup.

#### Script `bks-unpack.pl`

          #!/usr/bin/perl -w
          #$Id: bks.pl,v 1.1 2003/07/04 15:41:55 tvraman Exp tvraman $
          #Description: Bookshare downloader for Lynx
          use strict;
          my $location="$ENV{HOME}/books/book-share";
          my $password = 'xxxxxxx';
          my $grabbed = shift;
          my $target = shift;
          my $dir =qx(basename $target .bks);
          chomp $dir;
          my $where = "$location/$dir";
          qx(mkdir -p $where);
          qx(mv $grabbed  $where/$target);
          chdir $where;
          qx(echo $password | bks-unpack -q $target 1>&-
          2>&- &);

## Emacspeak, SuDoKu And History

Here is a small enhancement to playing SuDoKu in Emacspeak. The feature is probably generally useful i.e., it's not specific to eyes-free interaction, but its presence encourages one to try different solution strategies.

Commands `emacspeak-sudoku-history-push` bound to `m` and `emacspeak-sudoku-history-pop` bound to `M` allow one to mark interesting states in the game and return to these prior states with a single keystroke. This means that when one is confronted with one of two choices, with no apparent additional information on which route to take, it becomes possible to push that state on to the history stack, try one of the alternatives and backtrack if necessary.

## Emacspeak And Voice Locking Using Aural CSS

This is slightly reformatted from what was posted to the Emacspeak mailing list as separate message.

1. Emacspeak defines a number of voice overlays such as `voice-bolden`, and `voice-lighten` that can be applied to a given voice to change what it sounds like.
2. Voice overlays are defined in terms of Aural CSS (ACSS) to keep them independent of a specific TTS engine.
3. For each such overlay there is a corresponding `<overlay-name>-settings` variable that can be customized via custom.
4. The numbers in `voice-bolden-settings as an example`:

Setting | Value
--- | ---
family | nil
average-pitch | 1
pitch-range | 6
stress | 6
richness | nil
punctuation | nil

Unset values (`nil`) show up as "unspecified" in the customize interface.

1. Do not directly customize `voice-bolden` and friends, instead customize the corresponding `voice-bolden-settings`, since that ensures that all voices that are defined in terms of `voice-bolden` get correctly updated.
2. Discovering what to customize:

Command `emacspeak-show-personality-at-point` (bound by default to C-e M-v) will show you the value of properties personality and face at point. A recent update I implemented last weekend makes this more useful, so make sure you do a CVS update; earlier this command used to display the ACSS setting --- now it displays the abstract name. Describe-variable on these names should tell you what to customize; so as an example:

Put point on a comment line, and hit `C-e M-v`: you will hear

          Personality emacspeak-voice-lock-comment-personality
          Face font-lock-comment-delimiter-face

Describe-variable of `emacspeak-voice-lock-comment-personality` gives:

          emacspeak-voice-lock-comment-personality's value is
          acss-p0-s0-all

          Documentation:
          Personality used for font-lock-comment-face
          This personality uses  voice-monotone whose  effect can be changed
          globally by customizing voice-monotone-settings.

### How It All Works

Here is a brief explanation of the connection between `voice-bolden` and its associated `voice-bolden-settings`.

1. Voice settings are initially in `voice-bolden-settings` which is a list of numbers.
2. That list of numbers needs to be translated to appropriate device-specific codes to send to the TTS engine.
3. You do not want to do this translation each time you speak something.
4. So when `voice-bolden` is defined, the definition happens in two steps:

- The list of settings is stored away in `voice-bolden-settings`,
- A corresponding voice-name is generated --- `acss-a<n>-p<n>-r<n>-s<n>` and the corresponding control codes to send to the device are stored away in a hash-table keyed by the above symbol.
- Finally, `voice-bolden` is assigned the above symbol.

### What this gives is:

1. The ability to customize the voice via custom by editting the list of numbers in `voice-bolden-settings`
2. When that list is editted, `voice-bolden` is arranged to be updated automatically.

### Other Useful Commands

In addition, commands `emacspeak-wizards-generate-voice-sampler` can be useful in generating a buffer that shows what the various ACSS settings sound like. Command `emacspeak-wizards-voice-sampler` can be used to apply a specific voice to a region of text while experimenting with the various settings.

## Playing SuDoKu Using Auditory Feedback

Emacspeak speech-enables SuDoKu implemented by sudoku.el. Speech-enabling games is an effective means of discovering what additions one needs to make to an auditory interface for working effectively in an eyes-free environment --- this was aptly demonstrated a few years ago by identifying interesting conversational gestures by speech-enabling the game of `Tetris` --- see Conversational Gestures For The Audio Desktop from Assets 1998.

#### Advicing Interactive Commands

As with speech-enabling any Emacs module, `emacspeak-sudoku` advices all interactive commands to produce spoken feedback. In addition to speaking the cell moved to, all navigation commands produce an auditory icon that is a function of whether the cell value is mutable --- original values cannot be changed and this is indicated with a distinctive icon.

#### Additional Interactive Commands

Playing SuDoKu effectively requires one to build a good mental image of the state of the board as well as the ability to effectively query the game for currently active constraints. The eye's ability to quickly move around the board and perceive row, column and sub-square constraints needs to be compensated for in an eyes-free environment. As an example, it is too difficult to build the necessary mental model by just listening to the board spoken aloud, or by listening to idnividual cells by navigating to them.

Here are the set of additional interactive commands that needed to be added in order to be able to play the game effectively.

`r`
  Speak current row.
`c`
  Speak current column
`s`
  Speak current sub-square.
`R`
  Speak number of remaining cells in current row.
`C`
  Speak number of remaining cells in current column.
`S`
  Speak number of remaining cells in current sub-square.
`d`
  Move to the sub-square below the current sub-square.
`u`
  Move to the sub-square above the current sub-square.
`n`
  Move to the next sub-square.
`p`
  Move to the previous sub-square.
`a`
  Move to the beginning of current row.
`e`
  Move to the end of the current row.
`t`
  Move to the top of the current column.
`b`
  Move to the bottom of the current column.
`,`
  Speaks information about the overall distribution of numbers on the board.
  - `d` --- Conveys how many instances of each digit have been filled in.
  - `s` --- Conveys number of remaining cells in each sub-square.
  - `r` --- Conveys number of remaining cells in each row.
  - `c` --- Conveys number of remaining cells in each column.
`/`
  Speaks number of remaining cells in the current board.
`.`
  Speaks value in current cell.

Notes on how invormation is spoken:

- Numbers are spoken in groups of 3 to achieve effective intonation.
- When navigating by sub-squares, point always moves to the top left corner of the sub-square.
- Additional commands bound to `M-r`, `M-c` and `M-s` erase the current row, column or sub-square respectively. These commands would probably be convenient to have independent of whether one is using visual output.

#### Effectiveness Of The Resulting Interface

With the above interface in place, the simpler levels of the game are a breeze, levels difficult and evil are sufficiently challenging to be fun.

## Browsing Sourceforge Download Servers

Sourceforge is a nice service, but it can also be painful to use because of the heavy-weight Web page design, and the need to repeatedly click before you get the download you want.

The most irksome of these is the download mechanism provided by Sourceforge --- where you first need to browse a list of download servers, pick a mirror, and then download what you want. Emacspeak implements a Smart URL that enables one to download from Sourceforge in a single step.

By default, this uses a North American mirror; the behavior can be customized if outside the US. Use smart URL `Sourceforge Browse Mirror` and specify the name of a SF hosted project when prompted. This brings up the index page for the project's download area, sorted by date. Move to the bottom of the page and hit `b` to move to the latest available download.

The smart URL sets up the W3 buffer with a context-sensitive download function; when on a download link, hit `C-d` to start downloading. This command will prompt for the URL; rather than hitting `return` (which would bring you to the browse mirrors page, hit `M-p` to get the download URL for your SF mirror. Note that this wizard uses `GNU wget` to perform the download via Emacs module `w3-wget`.

## BBC Channels On Emacspeak

Since the BBC's various channels are what I listen to the most, launching BBC channels has always been a couple of keystrokes in Emacspeak. As a first step, directory `realaudio/radio` contains shortcut files for launching live streams from the various BBC channels.

In addition, module `emacspeak-url-template` defines a number of Smart URLs for single-click access to BBC programs. The ones I use the most are:

- Smart URL `BBC Channels On Demand`, and
- Smart URL `BBC Genres On Demand`

These smart URLs prompt for the channel or genre respectively and bring up a Web page that lists the various shows that are available --- note that the BBC archives shows for a whole week. The resulting Web page is easy to browse in W3; the most effective way to skim the buffer is to repeatedly hit `i` which moves through the various items on the page. Hitting `e e` (that's the letter `e` twice) while on a hyperlink will launch the corresponding media stream by calling a context-aware command that knows about transforming the URL to one that accesses the program stream; --- note that simply following the hyperlink will get you first to a page about the program, rather than to the program stream itself.

To find out what channels and genres are available, browse the BBC Web site --- channel and genre names are not hard-wired into Emacspeak since these can change over time with channels and genres being added or renamed.

## Emacspeak World Clock For Timezone Travel

Command `emacspeak-speak-time` bound to `C-e t` speaks the current time. An additional convenience offered by this keystroke is to get the time at a specified time zone using Emacs' completion facility.

To use this feature, simply precede the keystroke with an `interactive prefix arg` i.e., use `C-u C-e t`. This will prompt for the timezone in the minibuffer. Using two `C-u C-u` will set the default timezone after speaking the time --- a useful way of avoiding jet-lag as you travel.

## Emacspeak Web Wizards: Obtaining Context From The Calendar

Emacspeak implements a number of `smart URLs` in module `emacspeak-url-template.el` --- see earlier post on Web Command Line. Many of these `smart URLs` prompt the user for the date, e.g. you can use `smart URL` NPR On Demand to play archived NPR shows.

The most intuitive means of specifying a date is of course using a `calendar` that functions as a date-picker, and Emacs has a very powerful built-in calendar. Emacspeak ties these two together by arranging for commands that prompt for a date to use the current date in the Emacs Calendar as the default. So the easiest way to play NPR Morning Edition for Monday, January 2, 2006 is to do the following:

- Switch to the Emacs Calendar and move to the desired date Monday January 2, 2006 by pressing `gd`.
- Invoke the NPR On Demand `smart URL` by pressing `C-e u RET NPR RET`
- Specify the program code for Morning Edition by pressing `me RET`
- Hit enter to pick the default date that is offered in the minibuffer.
- Sit back and listen ...

## Viewing Atom Feeds Within Emacspeak

The most effective way of viewing Atom Feeds in Emacspeak is to use command `emacspeak-atom-display` and specifying the URL of the feed when prompted. Thus, `M-x emacspeak-atom-display RET http://emacspeak.blogspot.com/atom.xml` displays a Web page generated from the Emacspeak Blog.

Notice the following in the generated Web page:

- It starts with a navigable table of contents.
- Each Blog entry has a link labeled `edit` next to it.
- Each Blog entry ends with a link labeled `Bookmark`.
- There is a link labeled `Post` at the top of the page.

The above links help you easily create and edit posts to the Blog if you have write access using commands provided by module `atom-blogger`. Eventually, I may add commands to these hyperlinks to automatically invoke the appropriate command from `atom-blogger`; for now, I find it sufficiently convenient to copy the URL under point to the `kill-ring` and later yank it back into the minibuffer when prompted by `atom-blogger`.

Finally, note that this and subsequent posts to this Blog will show up automatically on the Emacspeak Mailing List at Vassar.

## Viewing Formatted Source Code In Emacs/W3

While reading online texts on programming in Python and Ruby, I noticed that Emacspeak was not announcing indented lines in preformatted source-code examples, even with `audio indentation` turned on. The reason is that many of these texts use an HTML non-breaking space for indentation, and though W3 was rendering these correctly, the default syntax table in W3 had not defined the resulting `octal 240` to be of class white-space. Consequently, Emacspeak's audio indentation code was not treating the non-breaking space as white space.

I've checked in a patch to `emacspeak-w3.el` that modifies the syntax table in `w3-mode` by adding the appropriate lines to `w3-mode-hook`.

## Speech-Enabled ATOM-Blogger

Module `atom-blogger` is a light-weight Emacs client for creating or editting blogger posts using ATOM. Emacspeak bundles `atom-blogger` and speech-enables it via module `emacspeak-atom-blogger`.

Module `emacspeak-setup.el` has been updated to set up the Emacs' `load-path` to locate package `atom-blogger`, so if correctly installed, Emacspeak users should be able to launch and use `atom-blogger` with no further configuration.

## Emacspeak And Ruby

Emacspeak now speech-enables ruby-mode to support developing Web applications using `Ruby On Rails`. I presently use `nxml-mode` for editing the `.rhtml` files, but am looking for an alternative to using multi-mode or its variants when editing the embedded Ruby code. Sadly, one has to turn off `nxml-mode`'s validity checking while editing `.rhtml` files --- otherwise it complains about the `<%` directives.

## Emacspeak Wizard: Recording Audio Streams For Later Playback

Emacspeak includes a large collection of wizards implemented in module `emacspeak-wizards.el` One of these ---`emacspeak-wizrds-rivo` works hand-in-hand with script `etc/rivo.pl` to provide a simple record for later playback facility that can be used to record live realaudio streams for future playback. This is useful for listening to live broadcasts at a more convenient time.

Wizard `emacspeak-wizrds-rivo` prompts for the time at which to record, the length of the recording, the stream to record, and the location in which the recording is to be stored. It then uses command `trplayer` (text-mode RealPlayer) with command `vsound` to capture the audio stream, and converts the result to MP3 using command `lame`. ToDo: With `mplayer` now able to play RealAudio streams, the `etc/rivo.pl` script should be updated to use `mplayer` since this will :

- Remove the `vsound` dependency.
- Enable us to record more than just RealAudio streams.

## Emacs Tip: Viewing Commands Available On A Prefix Key

Emacs, and consequently Emacspeak, uses a number of multi-key sequences. The initial key that makes up such a multi-key sequence --- AKA the `prefix-key` that leads to all Emacspeak commands is `C-e` (`control-e)`.

Pressing any `prefix-key` followed by the `help-key` (`C-h`) results in Emacs displaying a *Help* buffer that lists all key-sequences beginning with that prefix.

This can be a very useful way of quickly seeing what keyboard commands are available --- as the resulting listing is shorter than what is produced by `C-h b` (command describe-bindings) which lists all key-bindings.

To use this feature to review Emacspeak's key-bindings, I have now moved command `emacspeak-learn-emacs-mode` to `C-h C-l` and `C-e F1` from its original key-binding of `C-e C-h` --- thechange is checked into CVS.

## Using The New MPlayer With ALSA Support

New versions of the Linux `mplayer` can now play RealMedia files in addition to the various DVD and Windows audio and video streams. As an added bonus, `mplayer` can be built to use ALSA ---(note that default RPMs available on the Web still default to OSS as of December 2006). This, with the additional support for newer RealMedia formats has finally caused me to switch away from `trplayer` a---a command line RealPlayer that was built against RealPlayer 8.0

Note that building `mplayer` from source to include ALSA support, and locating all the codecs you need will require a few Google searches. Specifically, to play NPR streams, you will need to grab `avisynth.dll` from the SourceForge project of the same name. But once this is done, `mplayer` will happily play multiple streams of audio without requiring multichannel support from the sound card. For Emacspeak users this means that you get auditory icons, and more importantly software TTS while listening to audio streams.

To use software TTS while `mplayer` is playing audio streams requires that you use a TTS server that uses ALSA; the default Emacspeak servers still use OSS. To build a TTS server for IBM ViaVoice TTS, obtain Emacspeak sources from CVS, and follow the instructions in file `servers/linux-outloud/ALSA`.

As of a few weeks ago, The Emacspeak CVS repository has been updated so that all access to streaming media goes through `mplayer` by default. Make sure to configure your `mplayer` with a smaller cache size if you use it exclusively for streaming audio; by default it uses a rather large cache, and streaming realaudio often takes a long time to start before the cache is configured to be something smaller; I use a cache size of `64kb` on my laptop.

## Blogging From Inside Emacs

I'm posting this using a bare-boned `atom-blogger` that I implemented this morning. It uses `curl` to process the HTTP Post Request.

### Editting Previous Entries

What's more, the bare-bones atom-blogger can now edit previous posts. This is done by getting the desired entry, filtering it for elements that should not be present when submitting updates, and adding a `generator` element --- all of these steps are required by the Blogger API. Unwanted elements are filtered out using `xsltproc`.
