;;; Commentary:
;; Identica Mode is a major mode to check friends timeline, and update your
;; status on Emacs.
;; identica-mode.el is a major mode for Identica. Based on the twittering mode
;; version 0.6 by Y. Hayamizu and Tsuyoshi CHO found at
;; <http://hayamin.com/wiliki.cgi?twittering-mode-en&l=en>

;; Requirements
;; if using Emacs22 or previous, you'll need json.el
;; get it from http://edward.oconnor.cx/2006/03/json.el
;; json.el is part of Emacs23
;; To use the OAuth support, you need oauth.el
;; Downloadable from http://github.com/psanford/emacs-oauth/
;; If using Oauth with Emacs earlier than 23.3 you'll also need w3m.
;;; Install:
;; You can use M-x customize-group identica-mode to setup all settings or simply
;; add the following to your .emacs or your prefered customizations file
;; (require 'identica-mode)
;; (setq identica-username "yourusername")
;; If you want to use simple authentication add your password
;; (setq identica-password "yourpassword")
;; It is recommended to create a file ~/.authinfo with your login credentials
;; instead of storing your password in plain text, the file should have the
;; following contents:
;; machine servername login yourusername password yourpassword
;; Replace servername with your server (if Identica server use identi.ca)
;; yourusername and yourpassword with your information. If you setup your
;; authinfo file, you don't need to set identica-password variable anywhere
;; If you want to use OAuth authentication add the following
;; (setq identica-auth-mode "oauth")
;; If you want to post from the minibufer without having identica buffer active, add the following global keybinding.
;; Add this to send status updates
;; (global-set-key "\C-cip" 'identica-update-status-interactive)
;; Add this to send direct messages
;; (global-set-key "\C-cid" 'identica-direct-message-interactive)
;; If you want to connect to a custom statusnet server add this and change
;; identi.ca with your server's doman name.
;; (setq statusnet-server "identi.ca")
;; Start using with M-x identica
;; Follow me on identica: http://identi.ca/gabrielsaldana
