Org protocol is a mean to trigger custom actions in Emacs from external applications. Any application that supports calling external programs with an URL as argument may be used with this functionality. For example, you can configure bookmarks in your web browser to send a link to the current page to Org and create a note from it using capture (see Capture). You can also create a bookmark that tells Emacs to open the local source file of a remote website you are browsing.
In order to use Org protocol from an application, you need to register
‘org-protocol://’ as a valid scheme-handler. External calls are passed
to Emacs through the
emacsclient command, so you also need to ensure
an Emacs server is running. More precisely, when the application calls
Emacs calls the handler associated to ‘PROTOCOL’ with argument ‘(:key1 val1 :key2 val2)’.
Org protocol comes with three predefined protocols, detailed in the following
org-protocol-protocol-alist to define your own.
|• ||Store a link, push URL to kill-ring.|
