|
||
;;; Commentary:
|
||
|
||
;; This mode acts as a graphical user interface to GDB. You can interact with
|
||
;; GDB through the GUD buffer in the usual way, but there are also further
|
||
;; buffers which control the execution and describe the state of your program.
|
||
;; It separates the input/output of your program from that of GDB, if
|
||
;; required, and watches expressions in the speedbar. It also uses features of
|
||
;; Emacs 21 such as the fringe/display margin for breakpoints, and the toolbar
|
||
;; (see the GDB Graphical Interface section in the Emacs info manual).
|
||
|
||
;; Start the debugger with M-x gdba.
|
||
|
||
;; This file has evolved from gdba.el from GDB 5.0 written by Tom Lord and Jim
|
||
;; Kingdon and uses GDB's annotation interface. You don't need to know about
|
||
;; annotations to use this mode as a debugger, but if you are interested
|
||
;; developing the mode itself, then see the Annotations section in the GDB
|
||
;; info manual.
|
||
;;
|
||
;; GDB developers plan to make the annotation interface obsolete. A new
|
||
;; interface called GDB/MI (machine interface) has been designed to replace
|
||
;; it. Some GDB/MI commands are used in this file through the CLI command
|
||
;; 'interpreter mi <mi-command>'. A file called gdb-mi.el is included in the
|
||
;; GDB repository for future releases (6.2 onwards) that uses GDB/MI as the
|
||
;; primary interface to GDB. It is still under development and is part of a
|
||
;; process to migrate Emacs from annotations to GDB/MI.

If `gdb-many-windows' is nil (the default value) then gdb just

pops up the GUD buffer unless `gdb-show-main' is t. In this case

it starts with two windows: one displaying the GUD buffer and the

other with the source file with the main routine of the inferior.
|

If `gdb-many-windows' is t, regardless of the value of
|

`gdb-show-main', the layout below will appear unless
|
||
`gdb-use-inferior-io-buffer' is nil when the source buffer
|
||
occupies the full width of the frame. Keybindings are given in
|
||
relevant buffer.
|
||
|
||
Watch expressions appear in the speedbar/slowbar.
|
||
|
||
The following commands help control operation :
|
||
|
||
`gdb-many-windows' - Toggle the number of windows gdb uses.
|
||
`gdb-restore-windows' - To restore the window layout.
|
||
|
||
See Info node `(emacs)GDB Graphical Interface' for a more

detailed description of this mode.
