;;; Commentary:
;; This file implements links to open files in doc-view-mode.
;; Org-mode loads this module by default - if this is not what you want,
;; configure the variable `org-modules'.
;; The links take the form
;;
;; docview:<file path>::<page number>
;;
;; for example: [[docview:~/.elisp/org/doc/org.pdf::1][Org-Mode Manual]]
;;
;; Autocompletion for inserting links is supported; you will be
;; prompted for a file and a page number.
;;
;; If you use org-store-link in a doc-view mode buffer, the stored
;; link will point to the current page.
;;; Code:
(require 'org)
(declare-function doc-view-goto-page "doc-view" (page))
(declare-function doc-view-current-page "doc-view" (&optional win))
(org-add-link-type "docview" 'org-docview-open)
