;;; Commentary:
|
||
|
||
;; This package is for setting "bookmarks" in files. A bookmark
|
||
;; associates a string with a location in a certain file. Thus, you
|
||
;; can navigate your way to that location by providing the string.
|
||
;; See the "User Variables" section for customizations.
|
||
|
||
|
||
;;; Code:
|
||
|
||
(require 'pp)
|
||
(eval-when-compile (require 'cl-lib))
|
||
|
||
;;; Misc comments:
|
||
;;
|
||
;; If variable bookmark-use-annotations is non-nil, an annotation is
|
||
;; queried for when setting a bookmark.
|
||
;;
|
||
;; The bookmark list is sorted lexically by default, but you can turn
|
||
;; this off by setting bookmark-sort-flag to nil. If it is nil, then
|
||
;; the list will be presented in the order it is recorded
|
||
;; (chronologically), which is actually fairly useful as well.

|

;;
|
||
;; The format of `bookmark-alist' has changed twice in its lifetime.
|
||
;; This comment describes the three formats, FIRST, SECOND, and
|
||
;; CURRENT.
|
||
;;
|
||
;; The FIRST format was used prior to Emacs 20:
|
||
;;
|
||
;; ((BOOKMARK-NAME (FILENAME
|
||
;; STRING-IN-FRONT
|
||
;; STRING-BEHIND
|
||
;; POINT))
|
||
;; ...)
|
||
;;
|
||
;; The SECOND format was introduced in Emacs 20:
|
||
;;
|
||
;; ((BOOKMARK-NAME ((filename . FILENAME)
|
||
;; (position . POS)
|
||
;; (front-context-string . STR-AFTER-POS)
|
||
;; (rear-context-string . STR-BEFORE-POS)
|
||
;; (annotation . ANNOTATION)
|
||
;; (whatever . VALUE)
|
||
;; ...
|
||
;; ))
|
||
;; ...)
|
||
;;
|
||
;; The CURRENT format was introduced in Emacs 22:
|
||
;;
|
||
;; ((BOOKMARK-NAME (filename . FILENAME)
|
||
;; (position . POS)
|
||
;; (front-context-string . STR-AFTER-POS)
|
||
;; (rear-context-string . STR-BEFORE-POS)
|
||
;; (annotation . ANNOTATION)
|
||
;; (whatever . VALUE)
|
||
;; ...
|
||
;; )
|
||
;; ...)
|
||
;;
|
||
;; Both FIRST and SECOND have the same level of nesting: the cadr of a
|
||
;; bookmark record is a list of entry information. FIRST and SECOND
|
||
;; differ in the form of the record information: FIRST uses a list of
|
||
;; atoms, and SECOND uses an alist. In the FIRST format, the order of
|
||
;; the list elements matters. In the SECOND format, the order of the
|
||
;; alist elements is unimportant. The SECOND format facilitates the
|
||
;; addition of new kinds of elements, to support new kinds of
|
||
;; bookmarks or code evolution.
|
||
;;
|
||
;; The CURRENT format removes a level of nesting wrt FIRST and SECOND,
|
||
;; saving one cons cell per bookmark: the cadr of a bookmark record is
|
||
;; no longer a cons. Why that change was made remains a mystery --
|
||
;; just be aware of it. (Be aware too that this explanatory comment
|
||
;; was incorrect in Emacs 22 and Emacs 23.1.)
|
||
;;
|
||
;; To deal with the change from FIRST format to SECOND, conversion
|
||
;; code was added, and it is still in use. See
|
||
;; `bookmark-maybe-upgrade-file-format'.
|
||
;;
|
||
;; No conversion from SECOND to CURRENT is done. Instead, the code
|
||
;; handles both formats OK. It must continue to do so.
|
||
;;
