|
||
;;; 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 order to make the last active frame display that file location.
|
||
;;
|
||
;; Starting Speedbar:
|
||
;;
|
||
;; Simply type `M-x speedbar', and it will be autoloaded for you.
|
||
|
||
;; If you want to choose it from a menu, such as "Tools", you can do this:
|
||
;;
|
||
;; (define-key-after (lookup-key global-map [menu-bar tools])
|
||
;; [speedbar] '("Speedbar" . speedbar-frame-mode) [calendar])
|
||
;;
|
||
;; If you want to access speedbar using only the keyboard, do this:
|
||
;;
|
||
;; (global-set-key [f4] 'speedbar-get-focus)
|
||
;;
|
||
;; This will let you hit f4 (or whatever key you choose) to jump
|
||
;; focus to the speedbar frame. Pressing it again will bring you back
|
||
;; to the attached frame. Pressing RET or e to jump to a file
|
||
;; or tag will move you back to the attached frame. The command
|
||
;; `speedbar-get-focus' will also create a speedbar frame if it does
|
||
;; not exist.
|
||
;;
|
||
;; Customizing Speedbar:
|
||
;;
|
||
;; Once a speedbar frame is active, it takes advantage of idle time
|
||
;; to keep its contents updated. The contents is usually a list of
|
||
;; files in the directory of the currently active buffer. When
|
||
;; applicable, tags in the active file can be expanded.
|
||
;;
|
||
;; To add new supported files types into speedbar, use the function
|
||
;; `speedbar-add-supported-extension'. If speedbar complains that the
|
||
;; file type is not supported, that means there is no built in
|
||
;; support from imenu, and the etags part wasn't set up correctly. You
|
||
;; may add elements to `speedbar-supported-extension-expressions' as long
|
||
;; as it is done before speedbar is loaded.
|
||
;;
|
||
;; To prevent speedbar from following you into certain directories
|
||
;; use the function `speedbar-add-ignored-path-regexp' to add a new
|
||
;; regular expression matching a type of path. You may add list
|
||
;; elements to `speedbar-ignored-path-expressions' as long as it is
|
||
;; done before speedbar is loaded.
|
||
;;
|
||
;; To add new file types to imenu, see the documentation in the
|
||
;; file imenu.el that comes with Emacs. To add new file types which
|
||
;; etags supports, you need to modify the variable
|
||
;; `speedbar-fetch-etags-parse-list'.
|
||
;;
|
||
;; If the updates are going too slow for you, modify the variable
|
||
;; `speedbar-update-speed' to a longer idle time before updates.
|
||
;;
|
||
;; If you navigate directories, you will probably notice that you
|
||
;; will navigate to a directory which is eventually replaced after
|
||
;; you go back to editing a file (unless you pull up a new file.)
|
||
;; The delay time before this happens is in
|
||
;; `speedbar-navigating-speed', and defaults to 10 seconds.
|
||
;;
|
||
;; To enable mouse tracking with information in the minibuffer of
|
||
;; the attached frame, use the variable `speedbar-track-mouse-flag'.
|
||
;;
|
||
;; Tag layout can be modified through `speedbar-tag-hierarchy-method',
|
||
;; which controls how tags are layed out. It is actually a list of
|
||
;; functions that filter the data. The default groups large tag lists
|
||
;; into sub-lists. A long flat list can be used instead if needed.
|
||
;; Other filters can be easily added.
|
||
;;
|
||
;; AUCTEX users: The imenu tags for AUCTEX mode doesn't work very
|
||
;; well. Use the imenu keywords from tex-mode.el for better results.
|
||
;;
|
||
;; This file requires the library package assoc (association lists)
|
||
;;
|
||
;;; 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 `speedbar-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. At the moment very few functions may be
|
||
;; overridden, but more will be added as the need is discovered.

Each directory segment is a button which jumps speedbar's default

directory to that path. Buttons are activated by clicking `\\[speedbar-click]'.
|

In some situations using `\\[speedbar-power-click]' is a `power click' which will

to insert the directory listing into the current tree. Click on the

directory as the default.

Each line starting with [+] is a file. If the variable

files which don't have imenu support, but are not expressly ignored.

Files are completely ignored if they match `speedbar-file-unshown-regexp'

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
|

If you open tags, you might find a node starting with {+}, which is a
