;;; Commentary:
|
|
|
|
;; This file implements real bookmarks for Gnus, closely following the way
|
|
;; `bookmark.el' handles bookmarks. Most of the code comes from
|
|
;; `bookmark.el'.
|
|
;;
|
|
;; Set a Gnus bookmark:
|
|
;; M-x `gnus-bookmark-set' from the summary buffer.
|
|
;;
|
|
;; Jump to a Gnus bookmark:
|
|
;; M-x `gnus-bookmark-jump'.
|
|
;;
|
|
;; Display a list of bookmarks
|
|
;; M-x `gnus-bookmark-bmenu-list'.
|
|
;;
|
|
|
|
;;; Todo:
|
|
|
|
;; - add tags to bookmarks
|
|
;; - don't write file each time a bookmark is created
|
|
;; - better annotation interactive buffer
|
|
;; - edit annotation in gnus-bookmark-bmenu
|
|
;; - sort gnus-bookmark-buffer by author/subject/date/group/message-id
|
|
;; - auto-bmk-name customizable format
|
|
;; - renaming bookmarks in gnus-bookmark-bmenu-list
|
|
;; - better (formatted string) display in bmenu-list
|
|
|
|
;; - Integrate the `gnus-summary-*-bookmark' functionality
|
|
;; - Initialize defcustoms from corresponding `bookmark.el' variables?
|
