;; Keywords: weblog blogger cms movable type openweblog blog
;; URL: http://launchpad.net/weblogger-el
;; Version: 1.4.4

;; Package-Requires: ((xml-rpc "1.6.7"))

;;; Commentary:
;; weblogger.el implements the Blogger, MetaWeblog, Movable Type, and
;; LiveJournal APIs to talk to server-side weblog software.
;;; Installation:
;; If you use ELPA (http://tromey.com/elpa), you can install via the
;; M-x package-list-packages interface. This is preferrable as you
;; will have access to updates automatically.
;; Otherwise, just make sure this file and xml-rpc.el are in your
;; load-path (usually ~/.emacs.d is included) and put
;; (require 'weblogger) in your ~/.emacs or ~/.emacs.d/init.el file.
;;; Starting Out:
;; If you don't yet have a weblog, you can set one up for free on
;; various services. (I suggest OpenWeblog.com, but then I run that
;; site :) )
;;
;; To set up your profile:
;;
;; M-x weblogger-setup-weblog RET
;; You will be prompted for some information. The URL should be the
;; one that uses the API you're using, not the one you would use for
;; typing an entry. For instance, in wordpress, use
;; <blog-url>/xmlrpc.php.
;; *** FIXME This section is complete fantasy at the moment.
;; ;; If you already have a weblog, and your weblog supports RSD
;; ;; (http://archipelago.phrasewise.com/rsd), you can use
;; ;;
;; ;; M-x weblogger-discover-server RET url RET
;; ;;
;; ;; where url is the URL of your weblog. This will set up a
;; ;; ~/.webloggerrc file for you if you let it.
;; You can also set up your server information using
;;
;; M-x customize-group RET weblogger RET
;;
;;; Keymaps:
;;
;; I use the following commands in my .emacs file:
;;
;; (load-file "weblogger.el")
;; (global-set-key "\C-cbs" 'weblogger-start-entry)
;;
;; C-c b s will then switch to a new buffer where you can compose a
;; entry.
;;
;; C-x C-s -- post-and-publish current buffer to the weblog.
;; Calling weblogger-publish-entry with an prefix argument
;; (i.e. C-u C-x C-s) will prompt for which weblog
;; to use.
;;
;; C-c C-c -- save as draft and bury the buffer.
;;
;; C-c C-n -- post (but not publish) the current entry and
;; load the next entry.
;;
;; C-c C-p -- post (but not publish) the current entry and
;; load the previous entry.
;;
;; C-c C-k -- delete the current entry.
;;
;; M-g -- synchronise weblogger.el's idea of the entries available
;; with the weblog server.
;;
;; C-c C-t m -- edit the main template.
;;
;; C-c C-t a -- edit the Archive Index template
;;
;; C-c C-s s -- Change the server being used.
;;
;; C-c C-s w -- Change the weblog.
;;
;; C-c C-s u -- Change the user (re-login).
;;
;;
;; Notes:
;; ----
;;
;; This code was originally based on Simon Kittle's blogger.el
;; (http://www.tswoam.co.uk/files/blogger.el.txt), but where his
;; code calls a Perl program, this code uses xml-rpc.el. You can
;; get xml-rpc.el from <http://elisp.info/package/xml-rpc/>
;;
;; Differences between SK's blogger.el and weblogger.el
;;
;; - Doesn't need any external programs. Uses xml-rpc.el.
;; - I've added a bunch of defcustom's here to make this integrate
;; better with Emacs Customization interface.
;; - Created a *weblogger-entry* mode.
;; - Made selection of a weblog more intuitive. It queries the
;; server and allows the user to choose the name of the
;; weblog from a list.
;; - Prompt for weblog on initial entry if weblogger-id isn't set.
;; - Can "ping" http://weblogs.com/ and http://blo.gs/ whenever
;; you update.
;; - Can "scroll" through entries on the weblog server and edit them.
;; - Many other features.
;;
;; TODO: (low hanging fruit first?)
;; * Move APIs to their own file
;; * RSD
;; * Menus
;; * Toolbar
;; * More robust support for metaWebBlog API
;; * Support more than just the metaWebBlog API -- ATOM especially
;; ** WordPress "Page" selection and "Category" support
;; * Weblog creation using OpenWeblog.com
;; * Comments
;; * Develop a minor mode that will allow posting buffer contents
;; to a weblog. This way, you can work using nxml/sgml modes on a
;; buffer and then post the results directly.
;;
;; Bugs/Features:
;;
;; * When you delete a entry it gets deleted, but it doesn't
;; disappear from your entry ring until you sync (M-g) with the
;; server. But this could be construed as a (mis)feature.
;; * If the server isn't reachable, (weblogger-determine-capabilities)
;; will get the wrong information.
;; * Changed titles aren't put in the weblogger post ring.
;; * Dependency issues: Use GnuTLS (gnutls-cli) for SSL encryption
;; ** Otherwise, you may get /a lot/ of terminal beeps and errors
;; ** (This is a dependency of url.el, but is listed here for clarity.)
