;;; Commentary:
;;
;; The speedbar provides a frame in which files, and locations in
;; files are displayed. These items can be clicked on with mouse-2 in
;; to display that file location.
;;
;;; Customizing and Developing for speedbar
;;
;; Please see the speedbar manual for information.
;;
;;; Notes:
;;
;; AUC-TEX users: The imenu tags for AUC-TEX mode don't work very
;; well. Use the imenu keywords from tex-mode.el for better results.
;;
;;; Developing for speedbar
;;
;; Adding a speedbar specialized display mode:
;;
;; Speedbar can be configured to create a special display for certain
;; modes that do not display traditional file/tag data. Rmail, Info,
;; and the debugger are examples. These modes can, however, benefit
;; from a speedbar style display in their own way.
;;
;; If your `major-mode' is `foo-mode', the only requirement is to
;; create a function called `foo-speedbar-buttons' which takes one
;; argument, BUFFER. BUFFER will be the buffer speedbar wants filled.
;; In `foo-speedbar-buttons' there are several functions that make
;; building a speedbar display easy. See the documentation for
;; `speedbar-with-writable' (needed because the buffer is usually
;; read-only) `speedbar-make-tag-line', `speedbar-insert-button', and
;; `speedbar-insert-generic-list'. If you use
;; `speedbar-insert-generic-list', also read the doc for
;; `speedbar-tag-hierarchy-method' in case you wish to override it.
;; The macro `dframe-with-attached-buffer' brings you back to the
;; buffer speedbar is displaying for.
;;
;; For those functions that make buttons, the "function" should be a
;; symbol that is the function to call when clicked on. The "token"
;; is extra data you can pass along. The "function" must take three
;; parameters. They are (TEXT TOKEN INDENT). TEXT is the text of the
;; button clicked on. TOKEN is the data passed in when you create the
;; button. INDENT is an indentation level, or 0. You can store
;; indentation levels with `speedbar-make-tag-line' which creates a
;; line with an expander (eg. [+]) and a text button.
;;
;; Some useful functions when writing expand functions, and click
;; functions are `speedbar-change-expand-button-char',
;; `speedbar-delete-subblock', and `speedbar-center-buffer-smartly'.
;; The variable `speedbar-power-click' is set to t in your functions
;; when the user shift-clicks. This is an indication of anything from
;; refreshing cached data to making a buffer appear in a new frame.
;;
;; If you wish to add to the default speedbar menu for the case of
;; `foo-mode', create a variable `foo-speedbar-menu-items'. This
;; should be a list compatible with the `easymenu' package. It will
;; be spliced into the main menu. (Available with click-mouse-3). If
;; you wish to have extra key bindings in your special mode, create a
;; variable `foo-speedbar-key-map'. Instead of using `make-keymap',
;; or `make-sparse-keymap', use the function
;; `speedbar-make-specialized-keymap'. This lets you inherit all of
;; speedbar's default bindings with low overhead.
;;
;; Adding a speedbar top-level display mode:
;;
;; Unlike the specialized modes, there are no name requirements,
;; however the methods for writing a button display, menu, and keymap
;; are the same. Once you create these items, you can call the
;; function `speedbar-add-expansion-list'. It takes one parameter
;; which is a list element of the form (NAME MENU KEYMAP &rest
;; BUTTON-FUNCTIONS). NAME is a string that will show up in the
;; Displays menu item. MENU is a symbol containing the menu items to
;; splice in. KEYMAP is a symbol holding the keymap to use, and
;; BUTTON-FUNCTIONS are the function names to call, in order, to create
;; the display.
;; Another tweakable variable is `speedbar-stealthy-function-list'
;; which is of the form (NAME &rest FUNCTION ...). NAME is the string
;; name matching `speedbar-add-expansion-list'. (It does not need to
;; exist.). This provides additional display info which might be
;; time-consuming to calculate.
;; Lastly, `speedbar-mode-functions-list' allows you to set special
;; function overrides.
;;; TODO:
;; - Timeout directories we haven't visited in a while.

The first line represents the default directory of the speedbar frame.
Each directory segment is a button which jumps speedbar's default
directory to that directory. Buttons are activated by clicking `\\[speedbar-click]'.
In some situations using `\\[dframe-power-click]' is a `power click' which will
rescan cached items, or pop up new frames.
Each line starting with <+> represents a directory. Click on the <+>
to insert the directory listing into the current tree. Click on the
<-> to retract that list. Click on the directory name to go to that
directory as the default.
Each line starting with [+] is a file. If the variable
`speedbar-show-unknown-files' is t, the lines starting with [?] are
files which don't have imenu support, but are not expressly ignored.
Files are completely ignored if they match `speedbar-file-unshown-regexp'
which is generated from `completion-ignored-extensions'.
Files with a `*' character after their name are files checked out of a
version control system. (Currently only RCS is supported.) New
version control systems can be added by examining the documentation
for `speedbar-this-file-in-vc' and `speedbar-vc-check-dir-p'.
Files with a `#' or `!' character after them are source files that
have an object file associated with them. The `!' indicates that the
files is out of date. You can control what source/object associations
exist through the variable `speedbar-obj-alist'.
Click on the [+] to display a list of tags from that file. Click on
the [-] to retract the list. Click on the file name to edit the file
in the attached frame.
If you open tags, you might find a node starting with {+}, which is a
category of tags. Click the {+} to expand the category. Jump-able
tags start with >. Click the name of the tag to go to that position
