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.

40 ;; If variable bookmark-use-annotations is non-nil, an annotation is
41 ;; queried for when setting a bookmark.
42 ;;
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.
48 ;;; User Variables
51 "Setting, annotation and jumping to bookmarks."
56 "If non-nil, saving a bookmark queries for an annotation in a buffer."
62 "Controls when Emacs saves bookmarks to a file.
63 --> nil means never save bookmarks, except when `bookmark-save' is
65 --> t means save bookmarks when Emacs is killed.
66 --> Otherwise, it should be a number that is the frequency with which
67 the bookmark list is saved (i.e.: the number of times which
68 Emacs's bookmark list may be modified before it is automatically
69 saved.). If it is a number, Emacs will also automatically save
70 bookmarks when it is killed.
72 Therefore, the way to get it to save every time you make or delete a
73 bookmark is to set this variable to 1 (or 0, which produces the same
74 behavior.)
76 To specify the file in which to save them, modify the variable
77 `bookmark-default-file'."

92 ;; In case user set `bookmark-file' in her .emacs:

101 "Whether or not to make numbered backups of the bookmark file.
102 It can have four values: t, nil, `never', or `nospecial'.
103 The first three have the same meaning that they do for the
104 variable `version-control'; the value `nospecial' (the default) means
105 just use the value of `version-control'."
114 "Non-nil means bookmark functions ignore case in completion."
120 "Non-nil means that bookmarks will be displayed sorted by bookmark name.
121 Otherwise they will be displayed in LIFO order (that is, most
122 recently set ones come first, oldest ones come last)."
128 "Non-nil means show annotations when jumping to a bookmark."
133 "Non-nil means to use an immovable header line.
134 This is as opposed to inline text at the top of the buffer."
140 "Number of lines used for the *Bookmark List* header
144 "Number of columns (chars) used for the *Bookmark List* marks column,
148 "Column at which to display filenames in a buffer listing bookmarks.
149 You can toggle whether files are shown with \\<bookmark-bmenu-mode-map>\\[bookmark-bmenu-toggle-filenames]."
155 "Non-nil means show filenames when listing bookmarks.
156 A non-nil value may result in truncated bookmark names."

573 ;; please discuss it with other Emacs developers first.
574 ;;
575 ;; The format of `bookmark-alist' has changed twice in its lifetime.
576 ;; This comment describes the three formats, FIRST, SECOND, and
577 ;; CURRENT.
578 ;;
579 ;; The FIRST format was used prior to Emacs 20:
580 ;;
581 ;; ((BOOKMARK-NAME (FILENAME
582 ;; STRING-IN-FRONT
583 ;; STRING-BEHIND
584 ;; POINT))
585 ;; ...)
586 ;;
587 ;; The SECOND format was introduced in Emacs 20:
588 ;;
589 ;; ((BOOKMARK-NAME ((filename . FILENAME)
590 ;; (position . POS)
591 ;; (front-context-string . STR-AFTER-POS)
592 ;; (rear-context-string . STR-BEFORE-POS)
593 ;; (annotation . ANNOTATION)
594 ;; (whatever . VALUE)
595 ;; ...
596 ;; ))
597 ;; ...)
598 ;;
599 ;; The CURRENT format was introduced in Emacs 22:
600 ;;
601 ;; ((BOOKMARK-NAME (filename . FILENAME)
602 ;; (position . POS)
603 ;; (front-context-string . STR-AFTER-POS)
604 ;; (rear-context-string . STR-BEFORE-POS)
605 ;; (annotation . ANNOTATION)
606 ;; (whatever . VALUE)
607 ;; ...
608 ;; )
609 ;; ...)
610 ;;
611 ;; Both FIRST and SECOND have the same level of nesting: the cadr of a
612 ;; bookmark record is a list of entry information. FIRST and SECOND
613 ;; differ in the form of the record information: FIRST uses a list of
614 ;; atoms, and SECOND uses an alist. In the FIRST format, the order of
615 ;; the list elements matters. In the SECOND format, the order of the
616 ;; alist elements is unimportant. The SECOND format facilitates the
617 ;; addition of new kinds of elements, to support new kinds of
618 ;; bookmarks or code evolution.
619 ;;
620 ;; The CURRENT format removes a level of nesting wrt FIRST and SECOND,
621 ;; saving one cons cell per bookmark: the cadr of a bookmark record is
622 ;; no longer a cons. Why that change was made remains a mystery --
623 ;; just be aware of it. (Be aware too that this explanatory comment
624 ;; was incorrect in Emacs 22 and Emacs 23.1.)
625 ;;
626 ;; To deal with the change from FIRST format to SECOND, conversion
627 ;; code was added, and it is still in use. See
628 ;; `bookmark-maybe-upgrade-file-format'.
629 ;;
630 ;; No conversion from SECOND to CURRENT is done. Instead, the code
