;;; 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.
;;; Code:
(require 'pp)
(require 'tabulated-list)
(require 'text-property-search)
(require 'fringe) ; for builds --without-x
(eval-when-compile (require 'cl-lib))
;;; 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.

Bookmark functions update the value automatically.

(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)

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.

;; 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').
