|
|
|

|
|
|
+;; [bzg:] This is an adapted version of the planner-mode extension the
|
|
|
+;; was first posted by Geert Kloosterman <g.j.kloosterman@gmail.com> on
|
|
|
+;; the Planner mailing list.
|
|
|
+;;
|
|
|
+;; [dmg:] I have updated and extended the function to allow for
|
|
|
+;; handling of the selection (it is now available as a region, so it
|
|
|
+;; can be used in a template using %i )
|
|
|
+;;
|
|
|
+;;
|
|
|
+;; We want to be able to pass a URL and document title directly from a
|
|
|
+;; web browser to Emacs.
|
|
|
+;;
|
|
|
+;; We define a remember:// url handler in the browser and use a shell
|
|
|
+;; script to handle the protocol. This script passes the information
|
|
|
+;; to a running Emacs process (using emacsclient/gnuclient). We use
|
|
|
+;; bookmarklets to create the remember:// urls dynamicly.
|
|
|
+;;
|
|
|
+;; The protocol types currently recognized are:
|
|
|
+;;
|
|
|
+;; remember:// start `remember' with the url and title filled in
|
|
|
+;; annotation:// similar to `planner-annotation-as-kill' (org?)
|
|
|
+;;
|
|
|
+;; The urls used internally will have the following form:
|
|
|
+;;
|
|
|
+;; remember://<the web page url>::remember::<the title>::remember::<selection>
|
|
|
+;;
|
|
|
+;; The title will be url-hex-encoded.
|
|
|
+;;
|
|
|
+;; The bookmarklets:
|
|
|
+;;
|
|
|
+;;----------------------------------------------------------------------
|
|
|
+;; javascript:location.href='remember://' + location.href + \
|
|
|
+;; '::remember::' + escape(document.title) + '::remember::' + escape(window.getSelection())
|
|
|
+;;----------------------------------------------------------------------
|
|
|
+;; javascript:location.href='annotation://' + location.href + '::remember::' +\
|
|
|
+;; escape(document.title) ;;
|
|
|
+;;----------------------------------------------------------------------
|
|

|
|
|
+;; The handler

|
|
|
+;; To install:
|
|
|
+;;
|
|
|
+;; Step 0: Install this module
|
|
|
+;;
|
|
|
+;; * Install this script and require it in your .emacs (or wherever you
|
|
|
+;; want to do it)
|
|
|
+;;
|
|
|
+;; (require 'org-annotation-helper)
|
|
|
+;;
|
|
|
+;;
|
|
|
+;; Step 1: Install the remember script
|
|
|
+;;
|
|
|
+;; * Save the handler as a script, and make sure it is executable, i.e.
|
|
|
+;; remember
|
|
|
+;; * Try it:
|
|
|
+;; Make sure emacs is running and you have started its server mode (server-start)
|
|
|
+;; Run this command from the command line
|
|
|
+;; remember 'remember://http%3A//orgmode.org/::remember::Org-Mode%20Homepage::remember::Notes'
|
|
|
+;; Emacs should now show a remember window with a URL to remember.org
|
|
|
+;;
|
|
|
+;;
|
|
|
+;; Step 2: add two bookmarklets
|
|
|
+;;
|
|
|
+;; For firefox:
|
|
|
+;;
|
|
|
+;; * Right click on the bookmarks area of Firefox.
|
|
|
+;; * Select new bookmark.
|
|
|
+;; * In location fill the javascript code above (the bookmarklet)
|
|
|
+;; * Make sure "Load this bookmark in the sidebar is deselected
|
|
|
+;;
|
|
|
+;; Try it. You should have now a url that starts with "remember://"
|
|
|
+;; and your browser will not know what do to with it.
|
|
|
+;;
|
|
|
+;; Step 3: Add the handler for the "remember://" URI
|
|
|
+;;
|
|
|
+;; Firefox
|
|
|
+;;
|
|
|
+;; To add a protocol handler (eg: remember://) in Firefox, take the
|
|
|
+;; following steps:
|
|
|
+;;
|
|
|
+;; - type in "about:config" in the location bar
|
|
|
+;; - right click, select New --> String
|
|
|
+;; - the name should be "network.protocol-handler.app.remember"
|
|
|
+;; - the value should be the executable, eg. "org-annotation-helper".
|
|
|
+;; At least under Linux this does not need to be the full path to
|
|
|
+;; the executable.
|
|
|
+;;
|
|
|
+;; See http://kb.mozillazine.org/Register_protocol for more details.
|
|
|
+;;
|
|
|
+;; Opera
|
|
|
+;;
|
|
|
+;; In Opera add the protocol in the Preferences->Advanced->Programs
|
|
|
+;; dialog.
|
|
|
+;;
|
|
|
+;; Step 4: Configure a template
|
|
|
+;; I personally use the following template for this mode
|
|
|
+;;
|
|
|
+;; (?w "* %u %c \n\n%i" "~/working/trunk/org/bookmarks.org" "Web links")
|
|
|
+;;
|
|
|
+;; %c will be replaced with the hyperlink to the page, displaying the title of the page
|
|
|
+;; %i will be replaced with the selected text from the browser
|
|
|
+;; By default the new remember notes are placed in the
|
|
|
+;; bookmarks.org file under the "Web links" section, but it can be
|
|
|
+;; easily overriden with C-u C-c C-c
|
|
|
+;;
|
|
|
+;; Step 5:
|
|
|
+;; Enjoy
