;; Synopsis
|
|
|
|
|
;; ========
|
|
|
|
|
;;
|
|
|
|
|
;; Allows org-mode to make use of the Emacs `etags' system. Defines tag
|
|
|
|
|
;; destinations in org-mode files as any text between <<double angled
|
|
|
|
|
;; brackets>>. This allows the tags-generation program `exuberant ctags' to
|
|
|
|
|
;; parse these files and create tag tables that record where these
|
|
|
|
|
;; destinations are found. Plain [[links]] in org mode files which do not have
|
|
|
|
|
;; <<matching destinations>> within the same file will then be interpreted as
|
|
|
|
|
;; links to these 'tagged' destinations, allowing seamless navigation between
|
|
|
|
|
;; multiple org-mode files. Topics can be created in any org mode file and
|
|
|
|
|
;; will always be found by plain links from other files. Other file types
|
2012-01-10 10:56:15 +00:00
|
|
|
|
;; recognized by ctags (source code files, latex files, etc) will also be
|
2010-07-06 06:25:48 +00:00
|
|
|
|
;; available as destinations for plain links, and similarly, org-mode links
|
|
|
|
|
;; will be available as tags from source files. Finally, the function
|
|
|
|
|
;; `org-ctags-find-tag-interactive' lets you choose any known tag, using
|
|
|
|
|
;; autocompletion, and quickly jump to it.

;; Installation
|
|
|
|
|
;; ============
|
|
|
|
|
;;
|
|
|
|
|
;; Install org mode
|
|
|
|
|
;; Ensure org-ctags.el is somewhere in your emacs load path.
|
|
|
|
|
;; Download and install Exuberant ctags -- "http://ctags.sourceforge.net/"
|
|
|
|
|
;; Edit your .emacs file (see next section) and load emacs.
|
|
|
|
|
|
|
|
|
|
;; To put in your init file (.emacs):
|
|
|
|
|
;; ==================================
|
|
|
|
|
;;
|
|
|
|
|
;; Assuming you already have org mode installed and set up:
|
|
|
|
|
;;
|
|
|
|
|
;; (setq org-ctags-path-to-ctags "/path/to/ctags/executable")
|
|
|
|
|
;; (add-hook 'org-mode-hook
|
|
|
|
|
;; (lambda ()
|
|
|
|
|
;; (define-key org-mode-map "\C-co" 'org-ctags-find-tag-interactive)))
|
|
|
|
|
;;
|
|
|
|
|
;; By default, with org-ctags loaded, org will first try and visit the tag
|
|
|
|
|
;; with the same name as the link; then, if unsuccessful, ask the user if
|
|
|
|
|
;; he/she wants to rebuild the 'TAGS' database and try again; then ask if
|
|
|
|
|
;; the user wishes to append 'tag' as a new toplevel heading at the end of
|
|
|
|
|
;; the buffer; and finally, defer to org's default behaviour which is to
|
|
|
|
|
;; search the entire text of the current buffer for 'tag'.
|
|
|
|
|
;;
|
|
|
|
|
;; This behaviour can be modified by changing the value of
|
|
|
|
|
;; ORG-CTAGS-OPEN-LINK-FUNCTIONS. For example I have the following in my
|
|
|
|
|
;; .emacs, which describes the same behaviour as the above paragraph with
|
|
|
|
|
;; one difference:
|
|
|
|
|
;;
|
|
|
|
|
;; (setq org-ctags-open-link-functions
|
|
|
|
|
;; '(org-ctags-find-tag
|
|
|
|
|
;; org-ctags-ask-rebuild-tags-file-then-find-tag
|
|
|
|
|
;; org-ctags-ask-append-topic
|
|
|
|
|
;; org-ctags-fail-silently)) ; <-- prevents org default behaviour
|
|
|
|
|
;;
|
|
|
|
|
;;
|
|
|
|
|
;; Usage
|
|
|
|
|
;; =====
|
|
|
|
|
;;
|
|
|
|
|
;; When you click on a link "[[foo]]" and org cannot find a matching "<<foo>>"
|
|
|
|
|
;; in the current buffer, the tags facility will take over. The file TAGS in
|
|
|
|
|
;; the active directory is examined to see if the tags facility knows about
|
|
|
|
|
;; "<<foo>>" in any other files. If it does, the matching file will be opened
|
|
|
|
|
;; and the cursor will jump to the position of "<<foo>>" in that file.
|
|
|
|
|
;;
|
|
|
|
|
;; User-visible functions:
|
|
|
|
|
;; - `org-ctags-find-tag-interactive': type a tag (plain link) name and visit
|
|
|
|
|
;; it. With autocompletion. Bound to ctrl-O in the above setup.
|
|
|
|
|
;; - All the etags functions should work. These include:
|
|
|
|
|
;;
|
|
|
|
|
;; M-. `find-tag' -- finds the tag at point
|
|
|
|
|
;;
|
|
|
|
|
;; C-M-. find-tag based on regular expression
|
|
|
|
|
;;
|
|
|
|
|
;; M-x tags-search RET -- like C-M-. but searches through ENTIRE TEXT
|
|
|
|
|
;; of ALL the files referenced in the TAGS file. A quick way to
|
|
|
|
|
;; search through an entire 'project'.
|
|
|
|
|
;;
|
|
|
|
|
;; M-* "go back" from a tag jump. Like `org-mark-ring-goto'.
|
|
|
|
|
;; You may need to bind this key yourself with (eg)
|
|
|
|
|
;; (global-set-key (kbd "<M-kp-multiply>") 'pop-tag-mark)
|
|
|
|
|
;;
|
|
|
|
|
;; (see etags chapter in Emacs manual for more)
|
|
|
|
|

|
|
|
|
|
;;
|
|
|
|
|
;; Keeping the TAGS file up to date
|
|
|
|
|
;; ================================
|
|
|
|
|
;;
|
|
|
|
|
;; Tags mode has no way of knowing that you have created new tags by typing in
|
|
|
|
|
;; your org-mode buffer. New tags make it into the TAGS file in 3 ways:
|
|
|
|
|
;;
|
|
|
|
|
;; 1. You re-run (org-ctags-create-tags "directory") to rebuild the file.
|
|
|
|
|
;; 2. You put the function `org-ctags-ask-rebuild-tags-file-then-find-tag' in
|
|
|
|
|
;; your `org-open-link-functions' list, as is done in the setup
|
|
|
|
|
;; above. This will cause the TAGS file to be rebuilt whenever a link
|
|
|
|
|
;; cannot be found. This may be slow with large file collections however.
|
|
|
|
|
;; 3. You run the following from the command line (all 1 line):
|
|
|
|
|
;;
|
|
|
|
|
;; ctags --langdef=orgmode --langmap=orgmode:.org
|
|
|
|
|
;; --regex-orgmode="/<<([^>]+)>>/\1/d,definition/"
|
|
|
|
|
;; -f /your/path/TAGS -e -R /your/path/*.org
|
|
|
|
|
;;
|
|
|
|
|
;; If you are paranoid, you might want to run (org-ctags-create-tags
|
|
|
|
|
;; "/path/to/org/files") at startup, by including the following toplevel form
|
|
|
|
|
;; in .emacs. However this can cause a pause of several seconds if ctags has
|
|
|
|
|
;; to scan lots of files.
