;;; Commentary:
;; This is the beginnings of a library for interfacing with
;; twitter.com from Emacs. It is also (more importantly) some
;; interactive functions that use that library. It's a hack, of
;; course; RMS i am not. Maybe one of you real programmers would
;; like to clean it up?
;; This uses Twitter's XML-based api, not the JSON one because i
;; would like to avoid making the user install third-party libraries
;; to use it.
;; Use:
;; FOR POSTING
;; There are four main interactive functions:
;; M-x twit-post RET will prompt for you to type your post directly
;; in the minibuffer.
;; M-x twit-post-region RET will post the region and
;; M-x twit-post-buffer RET will post the entire contents of the
;; current buffer.
;; M-X twit-show-recent-tweets RET will create a new buffer and
;; show your most recent messages in it.
;; M-x twit-mode RET, if you want to bother, just binds the
;; interactive functions to some keys. Do C-h f RET twit-mode RET
;; for more info.
;; M-x twit-follow-recent-tweets RET will create a new buffer,
;; show the most recent tweets, and update it every 90 seconds (idle)
;; But remember that your posts can't be longer than 140 (`twit-size')
;; characters long. All of these functions will also prompt you for
;; your user name (usually the email address you signed up to twitter
;; with) and password the first time in a given Emacs session. Note
;; that twitter uses `Basic Authentication' for user authentication,
;; which translates to, basically none. It's not secure for anything
;; more than casual attacks.
;; FOR READING
;; This is a work in progress. Just stubs. I have to figure out
;; how to make some use out of `xml-parse-fragment'. Until then,
;; `twit-list-followers' is incredibly stupid, but works.
;; FOR HACKING
;; See `twit-post-function', which is the backend for posting, and
;; `twit-parse-xml' which grabs an xml file from HTTP and turns it
;; into a list structure (using `xml-parse-fragment'). This is a work
;; in progress.
;; Installing:
;; There's not much to it. It you want it always there and ready, you
;; can add something to your .emacs file like:
;; (load "twit")
;; (twit-mode t)
;; (setq twit-username "YOUR_USERNAME")
;; (setq twit-password "YOUR_PASSWORD")
;; (setq twit-favorite-friends
;; '("hitoriblog" "otsune" "masui" "miyagawa" "emacs"))
;; or get fancier, to the extent you want and know how (autoloading,
;; keybinding, etc).
;; Notes:
;; `twit-user' gets my vote for variable name of the year. Ditto
;; `twit-mode' for mode names.
;;; History:

;; Emacs xml and url packages; minor mode; a little
;; abstraction; some stubs for the reading functions.
;; * 0.0.3 -- Doc and other minor changes.
