7877f373 | 28 | ;; This file was written by Nick Roberts following the general design |
d0045ba0 | 29 | ;; used in gdb-ui.el for Emacs 22.1 - 23.1. It was further developed |
691cf4a0 NR |
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 | ||
ee1f1da9 SM |
46 | ;; This file uses GDB/MI as the primary interface to GDB. It runs gdb with |
47 | ;; GDB/MI (-interp=mi) and access CLI using "-interpreter-exec console | |
9e7056a5 | 48 | ;; cli-command". This code replaces gdb-ui.el and uses MI tokens instead |
ee1f1da9 | 49 | ;; of queues. Eventually MI should be asynchronous. |
691cf4a0 NR |
50 | |
51 | ;; Windows Platforms: | |
52 | ||
53 | ;; If you are using Emacs and GDB on Windows you will need to flush the buffer | |
54 | ;; explicitly in your program if you want timely display of I/O in Emacs. | |
55 | ;; Alternatively you can make the output stream unbuffered, for example, by | |
56 | ;; using a macro: | |
57 | ||
58 | ;; #ifdef UNBUFFERED | |
59 | ;; setvbuf (stdout, (char *) NULL, _IONBF, 0); | |
60 | ;; #endif | |
61 | ||
62 | ;; and compiling with -DUNBUFFERED while debugging. | |
63 | ||
64 | ;; If you are using Cygwin GDB and find that the source is not being displayed | |
65 | ;; in Emacs when you step through it, possible solutions are to: | |
66 | ||
67 | ;; 1) Use Cygwin X Windows and Cygwin Emacs. | |
68 | ;; (Since 22.1 Emacs builds under Cygwin.) | |
69 | ;; 2) Use MinGW GDB instead. | |
70 | ;; 3) Use cygwin-mount.el | |
71 | ||
72 | ;;; Mac OSX: | |
73 | ||
74 | ;; GDB in Emacs on Mac OSX works best with FSF GDB as Apple have made | |
75 | ;; some changes to the version that they include as part of Mac OSX. | |
76 | ;; This requires GDB version 7.0 or later (estimated release date Aug 2009) | |
fe7a3057 | 77 | ;; as earlier versions do not compile on Mac OSX. |
691cf4a0 NR |
78 | |
79 | ;;; Known Bugs: | |
80 | ||
81 | ;; 1) Stack buffer doesn't parse MI output if you stop in a routine without | |
82 | ;; line information, e.g., a routine in libc (just a TODO item). | |
83 | ||
84 | ;; TODO: | |
85 | ;; 2) Watch windows to work with threads. | |
86 | ;; 3) Use treebuffer.el instead of the speedbar for watch-expressions? | |
87 | ;; 4) Mark breakpoint locations on scroll-bar of source buffer? | |
