32 ;; The speedbar provides a frame in which files, and locations in
33 ;; files are displayed. These items can be clicked on with mouse-2 in
34 ;; to display that file location.
36 ;;; Customizing and Developing for speedbar
38 ;; Please see the speedbar manual for information.
42 ;; AUC-TEX users: The imenu tags for AUC-TEX mode don't work very
43 ;; well. Use the imenu keywords from tex-mode.el for better results.
45 ;;; Developing for speedbar
47 ;; Adding a speedbar specialized display mode:
49 ;; Speedbar can be configured to create a special display for certain
50 ;; modes that do not display traditional file/tag data. Rmail, Info,
51 ;; and the debugger are examples. These modes can, however, benefit
52 ;; from a speedbar style display in their own way.
54 ;; If your `major-mode' is `foo-mode', the only requirement is to
55 ;; create a function called `foo-speedbar-buttons' which takes one
56 ;; argument, BUFFER. BUFFER will be the buffer speedbar wants filled.
57 ;; In `foo-speedbar-buttons' there are several functions that make
58 ;; building a speedbar display easy. See the documentation for
59 ;; `speedbar-with-writable' (needed because the buffer is usually
60 ;; read-only) `speedbar-make-tag-line', `speedbar-insert-button', and
61 ;; `speedbar-insert-generic-list'. If you use
62 ;; `speedbar-insert-generic-list', also read the doc for
63 ;; `speedbar-tag-hierarchy-method' in case you wish to override it.
64 ;; The macro `dframe-with-attached-buffer' brings you back to the
65 ;; buffer speedbar is displaying for.
67 ;; For those functions that make buttons, the "function" should be a
68 ;; symbol that is the function to call when clicked on. The "token"
69 ;; is extra data you can pass along. The "function" must take three
70 ;; parameters. They are (TEXT TOKEN INDENT). TEXT is the text of the
71 ;; button clicked on. TOKEN is the data passed in when you create the
72 ;; button. INDENT is an indentation level, or 0. You can store
73 ;; indentation levels with `speedbar-make-tag-line' which creates a
74 ;; line with an expander (eg. [+]) and a text button.
76 ;; Some useful functions when writing expand functions, and click
77 ;; functions are `speedbar-change-expand-button-char',
78 ;; `speedbar-delete-subblock', and `speedbar-center-buffer-smartly'.
79 ;; The variable `speedbar-power-click' is set to t in your functions
80 ;; when the user shift-clicks. This is an indication of anything from
81 ;; refreshing cached data to making a buffer appear in a new frame.
83 ;; If you wish to add to the default speedbar menu for the case of
84 ;; `foo-mode', create a variable `foo-speedbar-menu-items'. This
85 ;; should be a list compatible with the `easymenu' package. It will
86 ;; be spliced into the main menu. (Available with click-mouse-3). If
87 ;; you wish to have extra key bindings in your special mode, create a
88 ;; variable `foo-speedbar-key-map'. Instead of using `make-keymap',
89 ;; or `make-sparse-keymap', use the function
90 ;; `speedbar-make-specialized-keymap'. This lets you inherit all of
91 ;; speedbar's default bindings with low overhead.
93 ;; Adding a speedbar top-level display mode:
95 ;; Unlike the specialized modes, there are no name requirements,
96 ;; however the methods for writing a button display, menu, and keymap
97 ;; are the same. Once you create these items, you can call the
98 ;; function `speedbar-add-expansion-list'. It takes one parameter
99 ;; which is a list element of the form (NAME MENU KEYMAP &rest
100 ;; BUTTON-FUNCTIONS). NAME is a string that will show up in the
101 ;; Displays menu item. MENU is a symbol containing the menu items to
102 ;; splice in. KEYMAP is a symbol holding the keymap to use, and
103 ;; BUTTON-FUNCTIONS are the function names to call, in order, to create
105 ;; Another tweakable variable is `speedbar-stealthy-function-list'
106 ;; which is of the form (NAME &rest FUNCTION ...). NAME is the string
107 ;; name matching `speedbar-add-expansion-list'. (It does not need to
108 ;; exist.). This provides additional display info which might be
109 ;; time-consuming to calculate.
110 ;; Lastly, `speedbar-mode-functions-list' allows you to set special
111 ;; function overrides.
