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.

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
browse-url is used to invoke the Web browser of
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.
These are needed only if installing package
stand-alone, i.e. outside of Emacspeak.
Unpack the tar archive and place the resulting
g-clientdirectory on your emacs
maketo 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
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 for expired 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-emailDefault email-id to use. Individual clients typically override this via user option
g-html-handlerName 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.
gblogger-blogbrings up the list of blogs owned by the currently authenticated user.
gblogger-new-entrytakes 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.
gblogger-atom-displaydisplays 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.
gblogger-edit-entrytakes 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
gblogger-edit-entryprovide a special command
C-c C-c) that submits the entry to blogger.
gblogger-delete-entrydeletes 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
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.
gcal-calendar-agendadisplays 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.
gcal-add-eventprompts for event details and adds it to the calendar.
gcal-accept-eventaccepts an event. Event is specified using the edit url of the event.
gcal-delete-eventdeletes 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
default; this can be overridden via option
greader-reading-listdisplays the reading list (river of news).
greader-feed-listdisplays a browsable Web page with pointers to subscribed feeds.
greader-find-feedssearches for matching feeds to subscribe.
greader-unsubscribe-feedare used to subscribe and unsubscribe.
greader-add-labelare 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.
