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". | |
32 | ||
33 | ;;; Commentary: | |
34 | ||
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 | |
42 | ;; manual). | |
43 | ||
44 | ;; M-x gdb will start the debugger. | |
45 | ||
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. | |
52 | ||
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. | |
56 | ;; | |
57 | ;; You need development version of GDB 7.0 for the thread buffer to work. | |
58 | ||
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. | |
61 | ||
62 | ;; Windows Platforms: | |
63 | ||
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 | |
67 | ;; using a macro: | |
68 | ||
69 | ;; #ifdef UNBUFFERED | |
70 | ;; setvbuf (stdout, (char *) NULL, _IONBF, 0); | |
71 | ;; #endif | |
72 | ||
73 | ;; and compiling with -DUNBUFFERED while debugging. | |
74 | ||
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: | |
77 | ||
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 | |
82 | ||
83 | ;;; Mac OSX: | |
84 | ||
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. | |
89 | ||
90 | ;;; Known Bugs: | |
91 | ||
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). | |
94 | ||
95 | ;; TODO: | |
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? | |
