28 | ;; This mode acts as a graphical user interface to GDB. You can interact with | |
29 | ;; GDB through the GUD buffer in the usual way, but there are also further | |
30 | ;; buffers which control the execution and describe the state of your program. | |
614963ba NR |
31 | ;; It separates the input/output of your program from that of GDB, if |
32 | ;; required, and displays expressions and their current values in their own | |
33 | ;; buffers. It also uses features of Emacs 21 such as the display margin for | |
34 | ;; breakpoints, and the toolbar (see the GDB Graphical Interface section in | |
35 | ;; the Emacs info manual). | |

38 | ||
39 | ;; This file has evolved from gdba.el from GDB 5.0 written by Tom Lord and Jim | |
40 | ;; Kingdon and uses GDB's annotation interface. You don't need to know about | |
41 | ;; annotations to use this mode as a debugger, but if you are interested | |
42 | ;; developing the mode itself, then see the Annotations section in the GDB | |
43 | ;; info manual. Some GDB/MI commands are also used through th CLI command | |
44 | ;; 'interpreter mi <mi-command>'. | |

73 | If `gdb-many-windows' is nil (the default value) then gdb just |
74 | pops up the GUD buffer unless `gdb-show-main' is t. In this case | |
75 | it starts with two windows: one displaying the GUD buffer and the | |
76 | other with the source file with the main routine of the debugee. | |
77 | ||
78 | If `gdb-many-windows' is t the layout below will appear | |

80 | `gdb-use-inferior-io-buffer' is nil when the source buffer | |

107 | All the buffers share the toolbar and source should always display in the same | |
108 | window e.g after typing g on a breakpoint in the breakpoints buffer. Breakpoint | |
109 | icons are displayed both by setting a break with gud-break and by typing break | |
110 | in the GUD buffer. | |
111 | ||
112 | This works best (depending on the size of your monitor) using most of the | |
113 | screen. | |
114 | ||
115 | Displayed expressions appear in separate frames. Arrays may be displayed | |
116 | as slices and visualised using the graph program from plotutils if installed. | |
117 | Pointers in structures may be followed in a tree-like fashion. | |
118 | ||
119 | The following interactive lisp functions help control operation : | |
120 | ||
121 | `gdb-many-windows' - Toggle the number of windows gdb uses. | |
122 | `gdb-restore-windows' - To restore the window layout." | |
