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

279 | ;; whatever the method *returns* is displayed in the buffer; thus, you | |
280 | ;; can filter the debugger's output, interpreting some and passing on | |

1452 | ;; | |
1453 | ;; INVOCATION NOTES: | |
1454 | ;; | |
1455 | ;; You invoke jdb-mode with: | |
1456 | ;; | |
1457 | ;; M-x jdb <enter> | |
1458 | ;; | |
1459 | ;; It responds with: | |
1460 | ;; | |
1461 | ;; Run jdb (like this): jdb | |
1462 | ;; | |
1463 | ;; type any jdb switches followed by the name of the class you'd like to debug. | |
1464 | ;; Supply a fully qualfied classname (these do not have the ".class" extension) | |
1465 | ;; for the name of the class to debug (e.g. "COM.the-kind.ddavies.CoolClass"). | |
1466 | ;; See the known problems section below for restrictions when specifying jdb | |
1467 | ;; command line switches (search forward for '-classpath'). | |
1468 | ;; | |
1469 | ;; You should see something like the following: | |
1470 | ;; | |
1471 | ;; Current directory is ~/src/java/hello/ | |
1472 | ;; Initializing jdb... | |
1473 | ;; 0xed2f6628:class(hello) | |
1474 | ;; > | |
1475 | ;; | |
1476 | ;; To set an initial breakpoint try: | |
1477 | ;; | |
1478 | ;; > stop in hello.main | |
1479 | ;; Breakpoint set in hello.main | |
1480 | ;; > | |
1481 | ;; | |
1482 | ;; To execute the program type: | |
1483 | ;; | |
1484 | ;; > run | |
1485 | ;; run hello | |
1486 | ;; | |
1487 | ;; Breakpoint hit: running ... | |
1488 | ;; hello.main (hello:12) | |
1489 | ;; | |
1490 | ;; Type M-n to step over the current line and M-s to step into it. That, | |
1491 | ;; along with the JDB 'help' command should get you started. The 'quit' | |
1492 | ;; JDB command will get out out of the debugger. There is some truly | |
1493 | ;; pathetic JDB documentation available at: | |
1494 | ;; | |
1495 | ;; http://java.sun.com/products/jdk/1.1/debugging/ | |
1496 | ;; | |
1497 | ;; KNOWN PROBLEMS AND FIXME's: | |
1498 | ;; | |
1499 | ;; Not sure what happens with inner classes ... haven't tried them. | |
1500 | ;; | |
1501 | ;; Does not grok UNICODE id's. Only ASCII id's are supported. | |
1502 | ;; | |
1503 | ;; You must not put whitespace between "-classpath" and the path to | |
1504 | ;; search for java classes even though it is required when invoking jdb | |
1505 | ;; from the command line. See gud-jdb-massage-args for details. | |
1506 | ;; The same applies for "-sourcepath". | |
1507 | ;; | |
1508 | ;; Note: The following applies only if `gud-jdb-use-classpath' is nil; | |
1509 | ;; refer to the documentation of `gud-jdb-use-classpath' and | |
1510 | ;; `gud-jdb-classpath',`gud-jdb-sourcepath' variables for information | |
1511 | ;; on using the classpath for locating java source files. | |
1512 | ;; | |
1513 | ;; If any of the source files in the directories listed in | |
1514 | ;; gud-jdb-directories won't parse you'll have problems. Make sure | |
1515 | ;; every file ending in ".java" in these directories parses without error. | |
1516 | ;; | |
1517 | ;; All the .java files in the directories in gud-jdb-directories are | |
1518 | ;; syntactically analyzed each time gud jdb is invoked. It would be | |
1519 | ;; nice to keep as much information as possible between runs. It would | |
1520 | ;; be really nice to analyze the files only as neccessary (when the | |
1521 | ;; source needs to be displayed.) I'm not sure to what extent the former | |
1522 | ;; can be accomplished and I'm not sure the latter can be done at all | |
1523 | ;; since I don't know of any general way to tell which .class files are | |
1524 | ;; defined by which .java file without analyzing all the .java files. | |
1525 | ;; If anyone knows why JavaSoft didn't put the source file names in | |
1526 | ;; debuggable .class files please clue me in so I find something else | |

2242 | ;; | |
2243 | ;; If the buffer looks like this: | |
2244 | ;; -------------------- | |
2245 | ;; (gdb) set args foo bar | |
2246 | ;; (gdb) -!- | |
2247 | ;; -------------------- | |
2248 | ;; (the -!- marks the location of point), and we type `C-x SPC' in a | |
2249 | ;; source file to set a breakpoint, we want the buffer to end up like | |
2250 | ;; this: | |
2251 | ;; -------------------- | |
2252 | ;; (gdb) set args foo bar | |
2253 | ;; Breakpoint 1 at 0x92: file make-docfile.c, line 49. | |
2254 | ;; (gdb) -!- | |
2255 | ;; -------------------- | |
2256 | ;; Essentially, the old prompt is deleted, and the command's output | |
2257 | ;; and the new prompt take its place. | |
2258 | ;; | |
2259 | ;; Not echoing the command is easy enough; you send it directly using | |
2260 | ;; process-send-string, and it never enters the buffer. However, | |
2261 | ;; getting rid of the old prompt is trickier; you don't want to do it | |
2262 | ;; when you send the command, since that will result in an annoying | |
2263 | ;; flicker as the prompt is deleted, redisplay occurs while Emacs | |
2264 | ;; waits for a response from the debugger, and the new prompt is | |
2265 | ;; inserted. Instead, we'll wait until we actually get some output | |
2266 | ;; from the subprocess before we delete the prompt. If the command | |
2267 | ;; produced no output other than a new prompt, that prompt will most | |
2268 | ;; likely be in the first chunk of output received, so we will delete | |
2269 | ;; the prompt and then replace it with an identical one. If the | |
2270 | ;; command produces output, the prompt is moving anyway, so the | |
2271 | ;; flicker won't be annoying. | |
2272 | ;; | |
2273 | ;; So - when we want to delete the prompt upon receipt of the next | |
2274 | ;; chunk of debugger output, we position gud-delete-prompt-marker at | |
2275 | ;; the start of the prompt; the process filter will notice this, and | |
2276 | ;; delete all text between it and the process output marker. If | |

2287 | You start it up with one of the commands M-x gdb, M-x sdb, M-x dbx, | |
2288 | M-x perldb, M-x xdb, or M-x jdb. Each entry point finishes by executing a | |
2289 | hook; `gdb-mode-hook', `sdb-mode-hook', `dbx-mode-hook', | |
2290 | `perldb-mode-hook', `xdb-mode-hook', or `jdb-mode-hook' respectively. | |
2291 | ||
2292 | After startup, the following commands are available in both the GUD | |
2293 | interaction buffer and any source buffer GUD visits due to a breakpoint stop | |
2294 | or step operation: | |
2295 | ||
2296 | \\[gud-break] sets a breakpoint at the current file and line. In the | |
2297 | GUD buffer, the current file and line are those of the last breakpoint or | |
2298 | step. In a source buffer, they are the buffer's file and current line. | |
2299 | ||
2300 | \\[gud-remove] removes breakpoints on the current file and line. | |
2301 | ||
2302 | \\[gud-refresh] displays in the source window the last line referred to | |
2303 | in the gud buffer. | |
2304 | ||
2305 | \\[gud-step], \\[gud-next], and \\[gud-stepi] do a step-one-line, | |
2306 | step-one-line (not entering function calls), and step-one-instruction | |
2307 | and then update the source window with the current file and position. | |
2308 | \\[gud-cont] continues execution. | |
2309 | ||
2310 | \\[gud-print] tries to find the largest C lvalue or function-call expression | |
2311 | around point, and sends it to the debugger for value display. | |
2312 | ||
2313 | The above commands are common to all supported debuggers except xdb which | |
2314 | does not support stepping instructions. | |
2315 | ||
2316 | Under gdb, sdb and xdb, \\[gud-tbreak] behaves exactly like \\[gud-break], | |
2317 | except that the breakpoint is temporary; that is, it is removed when | |
2318 | execution stops on it. | |
2319 | ||
2320 | Under gdb, dbx, and xdb, \\[gud-up] pops up through an enclosing stack | |
2321 | frame. \\[gud-down] drops back down through one. | |
2322 | ||
2323 | If you are using gdb or xdb, \\[gud-finish] runs execution to the return from | |
2324 | the current function and stops. | |
2325 | ||

2327 | with the prefix C-c, and in all buffers through the prefix C-x C-a. | |
