;;; Commentary:
|
||
|
||
;; This mode acts as a graphical user interface to GDB and works with Emacs
|
||
;; 22.x and the version of GDB with which it is distributed. You can interact
|
||
;; with GDB through the GUD buffer in the usual way, but there are also
|
||
;; buffers which control the execution and describe the state of your program.
|
||
;; It separates the input/output of your program from that of GDB and displays
|
||
;; expressions and their current values in their own buffers. 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 gdbmi.
|
||
|
||
;; This file 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 (as
|
||
;; used in gdb-ui.el) to GDB/MI. It runs gdb with GDB/MI (-interp=mi) and
|
||
;; access CLI using "-interpreter-exec console cli-command".
|
||
;;
|
||
;; Known Bugs:
|
||
;;
|
||
;; 1) To handle program input, if required, and to avoid extra output in the
|
||
;; GUD buffer you must not use run, step, next or continue etc but their MI
|
||
;; counterparts through gud-run, gud-step etc, e.g clicking on the appropriate
|
||
;; icon in the toolbar.
|
||
;;
|
||
;; 2) Some commands send extra prompts to the GUD buffer.
|
||
;;
|
||
;; TODO:
|
||
;; 1) Prefix MI commands with a token instead of queueing commands.
|
||
;; 2) Use MI command -data-read-memory for memory window.
|
||
;; 3) Use MI command -data-disassemble for disassembly window.
|
||
;; 4) Allow separate buffers for Inferior IO and GDB IO.
|
||
;; 5) Watch windows to work with threads.

"Run gdb on program FILE in buffer *gud-FILE*.
|
||
The directory containing FILE becomes the initial working directory
|
||
and source-file directory for your debugger.
|
||
|
||
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. Keybindings are
|
||
given in relevant buffer.
|
||
|
||
Watch expressions appear in the speedbar/slowbar.
|
||
|
||
The following interactive lisp functions 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.
