| 7877f373 | 28 | ;; This file was written by Nick Roberts following the general design |
| 691cf4a0 NR |
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 runs gdb with |
| 47 | ;; GDB/MI (-interp=mi) and access CLI using "-interpreter-exec console | |
| 48 | ;; cli-command". This code works without gdb-ui.el and uses MI tokens instead | |
| 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? | |
