27 | ||
13b80a60 | 28 | ;; The ancestral gdb.el was by W. Schelter <wfs@rascal.ics.utexas.edu> |
f4b643a1 | 29 | ;; It was later rewritten by rms. Some ideas were due to Masanobu. |
f961a17c | 30 | ;; Grand Unification (sdb/dbx support) by Eric S. Raymond <esr@thyrsus.com> |
13b80a60 | 31 | ;; The overloading code was then rewritten by Barry Warsaw <bwarsaw@cen.com>, |
6496f3d2 | 32 | ;; who also hacked the mode to use comint.el. Shane Hartman <shane@spr.com> |
0e0de659 | 33 | ;; added support for xdb (HPUX debugger). Rick Sladkey <jrs@world.std.com> |
f266485d | 34 | ;; wrote the GDB command completion code. Dave Love <d.love@dl.ac.uk> |
2291bfaa | 35 | ;; added the IRIX kluge, re-implemented the Mips-ish variant and added |
f4b643a1 | 36 | ;; a menu. Brian D. Carlstrom <bdc@ai.mit.edu> combined the IRIX kluge with |
c6094cae | 37 | ;; the gud-xdb-directories hack producing gud-dbx-directories. Derek L. Davies |
c3fd0eea | 38 | ;; <ddavies@world.std.com> added support for jdb (Java debugger.) |

2161 | ;; When we send a command to the debugger via gud-call, it's annoying |
2162 | ;; to see the command and the new prompt inserted into the debugger's | |
2163 | ;; buffer; we have other ways of knowing the command has completed. | |
2164 | ;; | |
2165 | ;; If the buffer looks like this: | |
2166 | ;; -------------------- | |
2167 | ;; (gdb) set args foo bar | |
2168 | ;; (gdb) -!- | |
2169 | ;; -------------------- | |
2170 | ;; (the -!- marks the location of point), and we type `C-x SPC' in a | |
2171 | ;; source file to set a breakpoint, we want the buffer to end up like | |
2172 | ;; this: | |
2173 | ;; -------------------- | |
2174 | ;; (gdb) set args foo bar | |
2175 | ;; Breakpoint 1 at 0x92: file make-docfile.c, line 49. | |
2176 | ;; (gdb) -!- | |
2177 | ;; -------------------- | |
2178 | ;; Essentially, the old prompt is deleted, and the command's output | |
2179 | ;; and the new prompt take its place. | |
2180 | ;; | |
2181 | ;; Not echoing the command is easy enough; you send it directly using | |
2182 | ;; process-send-string, and it never enters the buffer. However, | |
2183 | ;; getting rid of the old prompt is trickier; you don't want to do it | |
2184 | ;; when you send the command, since that will result in an annoying | |
2185 | ;; flicker as the prompt is deleted, redisplay occurs while Emacs | |
2186 | ;; waits for a response from the debugger, and the new prompt is | |
2187 | ;; inserted. Instead, we'll wait until we actually get some output | |
2188 | ;; from the subprocess before we delete the prompt. If the command | |
2189 | ;; produced no output other than a new prompt, that prompt will most | |
2190 | ;; likely be in the first chunk of output received, so we will delete | |
2191 | ;; the prompt and then replace it with an identical one. If the | |
2192 | ;; command produces output, the prompt is moving anyway, so the | |
2193 | ;; flicker won't be annoying. | |
2194 | ;; | |
2195 | ;; So - when we want to delete the prompt upon receipt of the next | |
2196 | ;; chunk of debugger output, we position gud-delete-prompt-marker at | |
2197 | ;; the start of the prompt; the process filter will notice this, and | |
2198 | ;; delete all text between it and the process output marker. If | |
2199 | ;; gud-delete-prompt-marker points nowhere, we leave the current | |
2200 | ;; prompt alone. | |

ee0155df ER |
