27 ;; This mode acts as a graphical user interface to GDB. You can interact with
28 ;; GDB through the GUD buffer in the usual way, but there are also further
29 ;; buffers which control the execution and describe the state of your program.
30 ;; It separates the input/output of your program from that of GDB, if
31 ;; required, and watches expressions in the speedbar. It also uses features of
32 ;; Emacs 21 such as the fringe/display margin for breakpoints, and the toolbar
33 ;; (see the GDB Graphical Interface section in the Emacs info manual).
35 ;; By default, M-x gdb will start the debugger.
37 ;; This file has evolved from gdba.el that was included with GDB 5.0 and
38 ;; written by Tom Lord and Jim Kingdon. It uses GDB's annotation interface.
39 ;; You don't need to know about annotations to use this mode as a debugger,
40 ;; but if you are interested developing the mode itself, see the Annotations
41 ;; section in the GDB info manual.
43 ;; GDB developers plan to make the annotation interface obsolete. A new
44 ;; interface called GDB/MI (machine interface) has been designed to replace it.
45 ;; Some GDB/MI commands are used in this file through the CLI command
46 ;; 'interpreter mi <mi-command>'. To help with the process of fully migrating
47 ;; Emacs from annotations to GDB/MI, there is an experimental package called
48 ;; gdb-mi in the Emacs Lisp Package Archive ("http://tromey.com/elpa/"). It
49 ;; comprises of modified gud.el and a file called gdb-mi.el which replaces
50 ;; gdb-ui.el. When installed, this overrides the current files and invoking
51 ;; M-x gdb will use GDB/MI directly (starts with "gdb -i=mi"). When deleted
52 ;; ('d' followed by 'x' in Package Menu mode), the files are deleted and old
53 ;; functionality restored. This provides a convenient way to review the
54 ;; current status/contribute to its improvement. For someone who just wants to
55 ;; use GDB, however, the current mode in Emacs 22 is a much better option.
56 ;; There is also a file, also called gdb-mi.el, a version of which is included
57 ;; the GDB distribution. This will probably only work with versions
58 ;; distributed with GDB 6.5 or later. Unlike the version in ELPA it works on
59 ;; top of gdb-ui.el and you can only start it with M-x gdbmi.
61 ;; This mode SHOULD WORK WITH GDB 5.0 or later but you will NEED AT LEAST
62 ;; GDB 6.0 to use watch expressions. It works best with GDB 6.4 or later
63 ;; where watch expressions will update more quickly.
65 ;;; Windows Platforms:
67 ;; If you are using Emacs and GDB on Windows you will need to flush the buffer
68 ;; explicitly in your program if you want timely display of I/O in Emacs.
69 ;; Alternatively you can make the output stream unbuffered, for example, by
73 ;; setvbuf (stdout, (char *) NULL, _IONBF, 0);
76 ;; and compiling with -DUNBUFFERED while debugging.
78 ;; If you are using Cygwin GDB and find that the source is not being displayed
79 ;; in Emacs when you step through it, possible solutions are to:
81 ;; 1) Use Cygwin X Windows and Cygwin Emacs.
82 ;; (Since 22.1 Emacs builds under Cygwin.)
83 ;; 2) Use MinGW GDB instead.
84 ;; 3) Use cygwin-mount.el
88 ;; 1) Cannot handle multiple debug sessions.
89 ;; 2) If you wish to call procedures from your program in GDB
90 ;; e.g "call myproc ()", "p mysquare (5)" then use level 2 annotations
91 ;; "gdb --annotate=2 myprog" to keep source buffer/selected frame fixed.
92 ;; 3) After detaching from a process, clicking on the "GO" icon on toolbar
93 ;; (gud-go) sends "continue" to GDB (should be "run").
97 ;; 1) Use MI command -data-read-memory for memory window.
98 ;; 2) Use tree-buffer.el (from ECB) instead of the speedbar for
99 ;; watch-expressions? Handling of watch-expressions needs to be
100 ;; overhauled to work for large arrays/structures by creating variable
101 ;; objects for visible watch-expressions only.
102 ;; 3) Mark breakpoint locations on scroll-bar of source buffer?
