||
;;; 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 and displays
|
||
;; expressions and their current values in their own buffers. It also uses
|
||
;; features of Emacs 21 such as the 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. Some GDB/MI commands are also used through th CLI command
|
||
;; 'interpreter mi <mi-command>'.

"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 starts with
|
||
just two windows : the GUD and the source buffer. If it is t the
|
||
following layout will appear (keybindings given in relevant buffer) :
|
||
|
||
---------------------------------------------------------------------
|
||
GDB Toolbar
|
||
---------------------------------------------------------------------
|
||
GUD buffer (I/O of GDB) | Locals buffer
|
||
|
|
||
|
|
||
|
|
||
---------------------------------------------------------------------
|
||
Source buffer | Input/Output (of debuggee) buffer
|
||
| (comint-mode)
|
||
|
|
||
|
|
||
|
|
||
|
|
||
|
|
||
|
|
||
---------------------------------------------------------------------
|
||
Stack buffer | Breakpoints buffer
|
||
RET gdb-frames-select | SPC gdb-toggle-breakpoint
|
||
| RET gdb-goto-breakpoint
|
||
| d gdb-delete-breakpoint
|
||
---------------------------------------------------------------------
|
||
|
||
All the buffers share the toolbar and source should always display in the same
|
||
window e.g after typing g on a breakpoint in the breakpoints buffer. Breakpoint
|
||
icons are displayed both by setting a break with gud-break and by typing break
|
||
in the GUD buffer.
|
||
|
||
This works best (depending on the size of your monitor) using most of the
|
||
screen.
|
||
|
||
Displayed expressions appear in separate frames. Arrays may be displayed
|
||
as slices and visualised using the graph program from plotutils if installed.
|
||
Pointers in structures may be followed in a tree-like fashion.
|
||
|
||
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."
