;;; Commentary:
|
|
|
|
;; This is yet another implementation to allow the annotation of a
|
|
;; file without modification of the file itself. The annotation is in
|
|
;; org syntax so you can use all of the org features you are used to.
|
|
|
|
;; To use you might put the following in your .emacs:
|
|
;;
|
|
;; (require 'org-annotate-file)
|
|
;; (global-set-key (kbd "C-c C-l") 'org-annotate-file) ; for example
|
|
;;
|
|
;; To change the location of the annotation file:
|
|
;;
|
|
;; (setq org-annotate-file-storage-file "~/annotated.org")
|
|
;;
|
|
;; Then when you visit any file and hit C-c C-l you will find yourself
|
|
;; in an org buffer on a headline which links to the file you were
|
|
;; visiting, e.g:
|
|
|
|
;; * ~/org-annotate-file.el
|
|
|
|
;; Under here you can put anything you like, save the file
|
|
;; and next time you hit C-c C-l you will hit those notes again.
|
|
;;
|
|
;; To put a subheading with a text search for the current line set
|
|
;; `org-annotate-file-add-search` to non-nil value. Then when you hit
|
|
;; C-c C-l (on the above line for example) you will get:
|
|
|
|
;; * ~/org-annotate-file.el
|
|
;; ** `org-annotate-file-add-search` to non-nil value. Then whe...
|
|
|
|
;; Note that both of the above will be links.
