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

557 ;; The format of `bookmark-alist' has changed twice in its lifetime.
558 ;; This comment describes the three formats, FIRST, SECOND, and

563 ;; ((BOOKMARK-NAME (FILENAME
564 ;; STRING-IN-FRONT
565 ;; STRING-BEHIND
566 ;; POINT))
567 ;; ...)
569 ;; The SECOND format was introduced in Emacs 20:
571 ;; ((BOOKMARK-NAME ((filename . FILENAME)
572 ;; (position . POS)
573 ;; (front-context-string . STR-AFTER-POS)
574 ;; (rear-context-string . STR-BEFORE-POS)
575 ;; (annotation . ANNOTATION)
576 ;; (whatever . VALUE)
577 ;; ...
578 ;; ))
579 ;; ...)
581 ;; The CURRENT format was introduced in Emacs 22:
583 ;; ((BOOKMARK-NAME (filename . FILENAME)
584 ;; (position . POS)
585 ;; (front-context-string . STR-AFTER-POS)
586 ;; (rear-context-string . STR-BEFORE-POS)
587 ;; (annotation . ANNOTATION)
588 ;; (whatever . VALUE)
589 ;; ...
590 ;; )
591 ;; ...)
593 ;; Both FIRST and SECOND have the same level of nesting: the cadr of a
594 ;; bookmark record is a list of entry information. FIRST and SECOND
595 ;; differ in the form of the record information: FIRST uses a list of
596 ;; atoms, and SECOND uses an alist. In the FIRST format, the order of
597 ;; the list elements matters. In the SECOND format, the order of the
598 ;; alist elements is unimportant. The SECOND format facilitates the
599 ;; addition of new kinds of elements, to support new kinds of
600 ;; bookmarks or code evolution.
