28 ;; This mode acts as a graphical user interface to GDB. You can interact with
29 ;; GDB through the GUD buffer in the usual way, but there are also further
30 ;; buffers which control the execution and describe the state of your program.
31 ;; It separates the input/output of your program from that of GDB, if
32 ;; required, and watches expressions in the speedbar. It also uses features of
33 ;; Emacs 21 such as the fringe/display margin for breakpoints, and the toolbar
34 ;; (see the GDB Graphical Interface section in the Emacs info manual).
36 ;; By default, M-x gdb will start the debugger. However, if you have customised
37 ;; gud-gdb-command-name, then start it with M-x gdba.
39 ;; This file has evolved from gdba.el that was included with GDB 5.0 and
40 ;; written by Tom Lord and Jim Kingdon. It uses GDB's annotation interface.
41 ;; You don't need to know about annotations to use this mode as a debugger,
42 ;; but if you are interested developing the mode itself, then see the
43 ;; Annotations section in the GDB info manual.
45 ;; GDB developers plan to make the annotation interface obsolete. A new
46 ;; interface called GDB/MI (machine interface) has been designed to replace
47 ;; it. Some GDB/MI commands are used in this file through the CLI command
48 ;; 'interpreter mi <mi-command>'. A file called gdb-mi.el is included with
49 ;; GDB (6.2 onwards) that uses GDB/MI as the primary interface to GDB. It is
50 ;; still under development and is part of a process to migrate Emacs from
51 ;; annotations to GDB/MI.
56 ;; 1) Use MI command -data-read-memory for memory window.
57 ;; 2) Highlight changed register values (use MI commands
58 ;; -data-list-register-values and -data-list-changed-registers instead
59 ;; of 'info registers'.
60 ;; 3) Use tree-widget.el instead of the speedbar for watch-expressions?
61 ;; 4) Mark breakpoint locations on scroll-bar of source buffer?
62 ;; 5) After release of 22.1 use '-var-list-children --all-values'
63 ;; and '-stack-list-locals 2' which need GDB 6.1 onwards.

131 If `gdb-many-windows' is nil (the default value) then gdb just
132 pops up the GUD buffer unless `gdb-show-main' is t. In this case
133 it starts with two windows: one displaying the GUD buffer and the
134 other with the source file with the main routine of the inferior.
136 If `gdb-many-windows' is t, regardless of the value of
137 `gdb-show-main', the layout below will appear unless
138 `gdb-use-inferior-io-buffer' is nil when the source buffer
139 occupies the full width of the frame. Keybindings are given in
142 Watch expressions appear in the speedbar/slowbar.
144 The following commands help control operation :
146 `gdb-many-windows' - Toggle the number of windows gdb uses.
147 `gdb-restore-windows' - To restore the window layout.
149 See Info node `(emacs)GDB Graphical Interface' for a more
150 detailed description of this mode.
