;;; 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.

|
||
;; - Timeout directories we haven't visited in a while.
