28 ;; This file was written by by Nick Roberts following the general design
29 ;; used in gdb-ui.el for Emacs 22.1 - 23.1. It is currently being developed
30 ;; by Dmitry Dzhus <dima@sphinx.net.ru> as part of the Google Summer
31 ;; of Code 2009 Project "Emacs GDB/MI migration".
35 ;; This mode acts as a graphical user interface to GDB. You can interact with
36 ;; GDB through the GUD buffer in the usual way, but there are also further
37 ;; buffers which control the execution and describe the state of your program.
38 ;; It separates the input/output of your program from that of GDB and displays
39 ;; expressions and their current values in their own buffers. It also uses
40 ;; features of Emacs 21 such as the fringe/display margin for breakpoints, and
41 ;; the toolbar (see the GDB Graphical Interface section in the Emacs info
44 ;; M-x gdb will start the debugger.
46 ;; This file uses GDB/MI as the primary interface to GDB. It is still under
47 ;; development and is part of a process to migrate Emacs from annotations (as
48 ;; used in gdb-ui.el) to GDB/MI. It runs gdb with GDB/MI (-interp=mi) and
49 ;; access CLI using "-interpreter-exec console cli-command". This code works
50 ;; without gdb-ui.el and uses MI tokens instead of queues. Eventually MI
51 ;; should be asynchronous.
53 ;; This mode will PARTLY WORK WITH RECENT GDB RELEASES (status in modeline
54 ;; doesn't update properly when execution commands are issued from GUD buffer)
55 ;; and WORKS BEST when GDB runs asynchronously: maint set linux-async on.
57 ;; You need development version of GDB 7.0 for the thread buffer to work.
59 ;; This file replaces gdb-ui.el and is for development with GDB. Use the
60 ;; release branch of Emacs 22 for the latest version of gdb-ui.el.
64 ;; If you are using Emacs and GDB on Windows you will need to flush the buffer
65 ;; explicitly in your program if you want timely display of I/O in Emacs.
66 ;; Alternatively you can make the output stream unbuffered, for example, by
70 ;; setvbuf (stdout, (char *) NULL, _IONBF, 0);
73 ;; and compiling with -DUNBUFFERED while debugging.
75 ;; If you are using Cygwin GDB and find that the source is not being displayed
76 ;; in Emacs when you step through it, possible solutions are to:
78 ;; 1) Use Cygwin X Windows and Cygwin Emacs.
79 ;; (Since 22.1 Emacs builds under Cygwin.)
80 ;; 2) Use MinGW GDB instead.
81 ;; 3) Use cygwin-mount.el
85 ;; GDB in Emacs on Mac OSX works best with FSF GDB as Apple have made
86 ;; some changes to the version that they include as part of Mac OSX.
87 ;; This requires GDB version 7.0 or later (estimated release date Aug 2009)
88 ;; as earlier versions don not compile on Mac OSX.
92 ;; 1) Stack buffer doesn't parse MI output if you stop in a routine without
93 ;; line information, e.g., a routine in libc (just a TODO item).
96 ;; 2) Watch windows to work with threads.
97 ;; 3) Use treebuffer.el instead of the speedbar for watch-expressions?
98 ;; 4) Mark breakpoint locations on scroll-bar of source buffer?

302 pops up the GUD buffer unless `gdb-show-main' is t. In this case
303 it starts with two windows: one displaying the GUD buffer and the
304 other with the source file with the main routine of the inferior.
306 If `gdb-many-windows' is t, regardless of the value of
307 `gdb-show-main', the layout below will appear unless

309 occupies the full width of the frame. Keybindings are shown in
312 Watch expressions appear in the speedbar/slowbar.
314 The following commands help control operation :
316 `gdb-many-windows' - Toggle the number of windows gdb uses.
317 `gdb-restore-windows' - To restore the window layout.
