;;
;; Intercept calls from emacsclient to trigger custom actions.
;;
;; This is done by advising `server-visit-files' to scan the list of filenames
;; for `org-protocol-the-protocol' and sub-protocols defined in
;; `org-protocol-protocol-alist' and `org-protocol-protocol-alist-default'.
;;
;; Any application that supports calling external programs with an URL
;; as argument may be used with this functionality.
;;
;;
;; Usage:
;; ------
;;
;;   1.) Add this to your init file (.emacs probably):
;;
;;       (add-to-list 'load-path "/path/to/org-protocol/")
;;       (require 'org-protocol)
;;
;;   3.) Ensure emacs-server is up and running.
;;   4.) Try this from the command line (adjust the URL as needed):
;;
;;       $ emacsclient \
;;         org-protocol://store-link://http:%2F%2Flocalhost%2Findex.html/The%20title
;;
;;   5.) Optionally add custom sub-protocols and handlers:
;;
;;       (setq org-protocol-protocol-alist
;;             '(("my-protocol"
;;                :protocol "my-protocol"
;;                :function my-protocol-handler-function)))
;;
;;       A "sub-protocol" will be found in URLs like this:
;;
;;           org-protocol://sub-protocol://data
;;
;; If it works, you can now setup other applications for using this feature.
;;
;;
;; As of March 2009 Firefox users follow the steps documented on
;; http://kb.mozillazine.org/Register_protocol, Opera setup is described here:
;; http://www.opera.com/support/kb/view/535/
;;
;;
;; Documentation
;; -------------
;;
;; org-protocol.el comes with and installs handlers to open sources of published
;; online content, store and insert the browser's URLs and cite online content
;; by clicking on a bookmark in Firefox, Opera and probably other browsers and
;; applications:
;;
;;   * `org-protocol-open-source' uses the sub-protocol \"open-source\" and maps
;;     URLs to local filenames defined in `org-protocol-project-alist'.
;;
;;   * `org-protocol-store-link' stores an Org-link (if Org-mode is present) and
;;     pushes the browsers URL to the `kill-ring' for yanking.  This handler is
;;     triggered through the sub-protocol \"store-link\".
;;
;;   * Call `org-protocol-capture' by using the sub-protocol \"capture\".  If
;;     Org-mode is loaded, Emacs will pop-up a capture buffer and fill the
;;     template with the data provided.  I.e. the browser's URL is inserted as an
;;     Org-link of which the page title will be the description part.  If text
;;     was select in the browser, that text will be the body of the entry.
;;
;;   * Call `org-protocol-remember' by using the sub-protocol \"remember\".
;;     This is provided for backward compatibility.
;;     You may read `org-capture' as `org-remember' throughout this file if
;;     you still use `org-remember'.
;;
;; You may use the same bookmark URL for all those standard handlers and just
;; adjust the sub-protocol used:
;;
;;     location.href='org-protocol://sub-protocol://'+
;;           encodeURIComponent(location.href)+'/'+
;;           encodeURIComponent(document.title)+'/'+
;;           encodeURIComponent(window.getSelection())
;;
;; The handler for the sub-protocol \"capture\" detects an optional template
;; char that, if present, triggers the use of a special template.
;; Example:
;;
;;     location.href='org-protocol://sub-protocol://x/'+ ...
;;
;;  use template ?x.
;;
;; Note, that using double slashes is optional from org-protocol.el's point of
;; view because emacsclient squashes the slashes to one.
;;

;; provides: 'org-protocol

Each element of this list must be of the form:

  (module-name :property value property: value ...)

where module-name is an arbitrary name. All the values are strings.

Possible properties are:

  :online-suffix     - the suffix to strip from the published URLs
  :working-suffix    - the replacement for online-suffix
  :base-url          - the base URL, e.g. http://www.example.com/project/
                       Last slash required.
  :working-directory - the local working directory. This is, what base-url will
                       be replaced with.
  :redirects         - A list of cons cells, each of which maps a regular
                       expression to match to a path relative to :working-directory.

Example:

   (setq org-protocol-project-alist
       '((\"http://orgmode.org/worg/\"
          :online-suffix \".php\"
          :working-suffix \".org\"

          :working-directory \"/home/user/org/\"
          :rewrites ((\"org/?$\" . \"index.php\")))))

   The last line tells `org-protocol-open-source' to open
   /home/user/org/index.php, if the URL cannot be mapped to an existing
   file, and ends with either \"org\" or \"org/\".

Consider using the interactive functions `org-protocol-create' and
`org-protocol-create-for-org' to help you filling this variable with valid contents."

  "* Register custom handlers for org-protocol.

Each element of this list must be of the form:

  (module-name :protocol protocol :function func :kill-client nil)

protocol - protocol to detect in a filename without trailing colon and slashes.
           See rfc1738 section 2.1 for more on this.
           If you define a protocol \"my-protocol\", `org-protocol-check-filename-for-protocol'
           will search filenames for \"org-protocol:/my-protocol:/\"
           and trigger your action for every match. `org-protocol' is defined in
           `org-protocol-the-protocol'. Double and triple slashes are compressed
           to one by emacsclient.

function - function that handles requests with protocol and takes exactly one
           argument: the filename with all protocols stripped. If the function
           returns nil, emacsclient and -server do nothing. Any non-nil return
           value is considered a valid filename and thus passed to the server.

           `org-protocol.el provides some support for handling those filenames,
           if you stay with the conventions used for the standard handlers in
           `org-protocol-protocol-alist-default'. See `org-protocol-split-data'.

kill-client - If t, kill the client immediately, once the sub-protocol is
           detected. This is necessary for actions that can be interrupted by
           `C-g' to avoid dangling emacsclients. Note, that all other command
           line arguments but the this one will be discarded, greedy handlers
           still receive the whole list of arguments though.

Here is an example:

  (setq org-protocol-protocol-alist
