;;; 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.
;;
;; Type `M-x customize-group RET bookmark RET' for user options.

;;; Misc comments:
;;
;; 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.

  "Association list of bookmark names and their parameters.
Bookmark functions update the value automatically.
You probably do NOT want to change the value yourself.

The value is an alist whose elements are the form

 (BOOKMARK-NAME . PARAM-ALIST)

or the deprecated form (BOOKMARK-NAME PARAM-ALIST).  The alist is
ordered from most recently created bookmark at the front to least
recently created bookmark at the end.

BOOKMARK-NAME is the name you gave to the bookmark when creating it.

PARAM-ALIST is an alist of bookmark information.  The order of the
entries in PARAM-ALIST is not important.  The default entries are
described below.  An entry with a key but null value means the entry
is not used.

 (filename . FILENAME)
 (buf . BUFFER-OR-NAME)
 (position . POS)
 (front-context-string . STR-AFTER-POS)
 (rear-context-string  . STR-BEFORE-POS)
 (handler . HANDLER)
 (annotation . ANNOTATION)

FILENAME names the bookmarked file.
BUFFER-OR-NAME is a buffer or the name of a buffer that is used
  if FILENAME is not defined or it refers to a non-existent file.
POS is the bookmarked buffer position.
STR-AFTER-POS is buffer text that immediately follows POS.
STR-BEFORE-POS is buffer text that immediately precedes POS.
ANNOTATION is a string that describes the bookmark.
  See options `bookmark-use-annotations' and
  `bookmark-automatically-show-annotations'.
HANDLER is a function that provides the `bookmark-jump' behavior for a
specific kind of bookmark instead of the default `bookmark-default-handler'.
This is the case for Info bookmarks, for instance.  HANDLER must accept
a bookmark as its single argument.

A function `bookmark-make-record-function' may define additional entries
in PARAM-LIST that can be used by HANDLER.")

;;; File format stuff

;; *IMPORTANT NOTICE* If you are thinking about modifying (redefining)
;; the bookmark file format -- please don't.  The current format
;; should be extensible enough.  If you feel the need to change it,
;; please discuss it with other Emacs developers first.
;;
;; 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, which is no longer used and has been declared
;; obsolete.  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.
;;
;; See the doc string of `bookmark-alist' for information about the
;; elements that define a bookmark (e.g. `filename').
