| ;;; Commentary: | |
| ;; This mode acts as a graphical user interface to GDB. You can interact with | |
| ;; GDB through the GUD buffer in the usual way, but there are also further | |
| ;; buffers which control the execution and describe the state of your program. | |
| ;; It separates the input/output of your program from that of GDB, if | |
| ;; required, and watches expressions in the speedbar. It also uses features of | |
| ;; Emacs 21 such as the fringe/display margin for breakpoints, and the toolbar | |
| ;; (see the GDB Graphical Interface section in the Emacs info manual). | |
| ;; By default, M-x gdb will start the debugger. | |
| ;; This file has evolved from gdba.el that was included with GDB 5.0 and | |
| ;; written by Tom Lord and Jim Kingdon. It uses GDB's annotation interface. | |
| ;; You don't need to know about annotations to use this mode as a debugger, | |
| ;; but if you are interested developing the mode itself, see the Annotations | |
| ;; section in the GDB info manual. | |
| ;; GDB developers plan to make the annotation interface obsolete. A new | |
| ;; interface called GDB/MI (machine interface) has been designed to replace it. | |
| ;; Some GDB/MI commands are used in this file through the CLI command | |
| ;; 'interpreter mi <mi-command>'. To help with the process of fully migrating | |
| ;; Emacs from annotations to GDB/MI, there is an experimental package called | |
| ;; gdb-mi in the Emacs Lisp Package Archive ("http://tromey.com/elpa/"). It | |
| ;; comprises of modified gud.el and a file called gdb-mi.el which replaces | |
| ;; init-gdb.el. When installed, this overrides the current files and invoking | |
| ;; M-x gdb will use GDB/MI directly (starts with "gdb -i=mi"). When deleted | |
| ;; ('d' followed by 'x' in Package Menu mode), the files are deleted and old | |
| ;; functionality restored. This provides a convenient way to review the | |
| ;; current status/contribute to its improvement. For someone who just wants to | |
| ;; use GDB, however, the current mode in Emacs 22 is a much better option. | |
| ;; There is also a file, also called gdb-mi.el, a version of which is included | |
| ;; the GDB distribution. This will probably only work with versions | |
| ;; distributed with GDB 6.5 or later. Unlike the version in ELPA it works on | |
| ;; top of init-gdb.el and you can only start it with M-x gdbmi. | |
| ;; This mode SHOULD WORK WITH GDB 5.0 or later but you will NEED AT LEAST | |
| ;; GDB 6.0 to use watch expressions. It works best with GDB 6.4 or later | |
| ;; where watch expressions will update more quickly. | |
| ;;; Windows Platforms: | |
| ;; If you are using Emacs and GDB on Windows you will need to flush the buffer | |
| ;; explicitly in your program if you want timely display of I/O in Emacs. | |
| ;; Alternatively you can make the output stream unbuffered, for example, by | |
| ;; using a macro: | |
| ;; #ifdef UNBUFFERED | |
| ;; setvbuf (stdout, (char *) NULL, _IONBF, 0); | |
| ;; #endif | |
| ;; and compiling with -DUNBUFFERED while debugging. | |
| ;; If you are using Cygwin GDB and find that the source is not being displayed | |
| ;; in Emacs when you step through it, possible solutions are to: | |
| ;; 1) Use Cygwin X Windows and Cygwin Emacs. | |
| ;; (Since 22.1 Emacs builds under Cygwin.) | |
| ;; 2) Use MinGW GDB instead. | |
| ;; 3) Use cygwin-mount.el | |
| ;;; Mac OSX: | |
| ;; GDB in Emacs on Mac OSX works best with FSF GDB as Apple have made | |
| ;; some changes to the version that they include as part of Mac OSX. | |
| ;; This requires GDB version 7.0 or later (estimated release date June 2009) | |
| ;; as earlier versions don not compile on Mac OSX. | |
| ;;; Known Bugs: | |
| ;; 1) Cannot handle multiple debug sessions. | |
| ;; 2) If you wish to call procedures from your program in GDB | |
| ;; e.g "call myproc ()", "p mysquare (5)" then use level 2 annotations | |
| ;; "gdb --annotate=2 myprog" to keep source buffer/selected frame fixed. | |
| ;; 3) After detaching from a process, clicking on the "GO" icon on toolbar | |
| ;; (gud-go) sends "continue" to GDB (should be "run"). | |
| ;;; TODO: | |
| ;; 1) Use MI command -data-read-memory for memory window. | |
| ;; 2) Use tree-buffer.el (from ECB) instead of the speedbar for | |
| ;; watch-expressions? Handling of watch-expressions needs to be | |
| ;; overhauled to work for large arrays/structures by creating variable | |
| ;; objects for visible watch-expressions only. | |
| ;; 3) Mark breakpoint locations on scroll-bar of source buffer? | |
