;;; Commentary:
|
|
|
|
;; This file implements links to an IRC session from within Org mode.
|
|
;; Org mode loads this module by default - if this is not what you want,
|
|
;; configure the variable `org-modules'.
|
|
;;
|
|
;; Please customize the variable `org-modules' to select
|
|
;; extensions you would like to use, and to deselect those which you don't
|
|
;; want.
|
|
;;
|
|
;; Please note that at the moment only ERC is supported. Other clients
|
|
;; shouldn't be difficult to add though.
|
|
;;
|
|
;; Then set `org-irc-link-to-logs' to non-nil if you would like a
|
|
;; file:/ type link to be created to the current line in the logs or
|
|
;; to t if you would like to create an irc:/ style link.
|
|
;;
|
|
;; Links within an org buffer might look like this:
|
|
;;
|
|
;; [[irc:/irc.libera.chat/#emacs/bob][chat with bob in #emacs on Libera.Chat]]
|
|
;; [[irc:/irc.libera.chat/#emacs][#emacs on Libera.Chat]]
|
|
;; [[irc:/irc.libera.chat/]]
|
|
;;
|
|
;; If, when the resulting link is visited, there is no connection to a
|
|
;; requested server then one will be created.
