;;; Commentary:
|
|
|
|
;; This file implements links to Info nodes from within Org-mode.
|
|
;; Org-mode loads this module by default - if this is not what you want,
|
|
;; configure the variable `org-modules'.
|
|
|
|
;;; Code:
|
|
|
|
(require 'org)
|
|
|
|
;; Declare external functions and variables
|
|
|
|
(declare-function Info-find-node "info" (filename nodename
|
|
&optional no-going-back))
|
|
(defvar Info-current-file)
|
|
(defvar Info-current-node)
|
|
|
|
;; Install the link type
|
|
(org-add-link-type "info" 'org-info-open)
|
|
(add-hook 'org-store-link-functions 'org-info-store-link)
|
|
|
|
;; Implementation
|
|
