27 | ;; The ancestral gdb.el was by W. Schelter <wfs@rascal.ics.utexas.edu>. |
28 | ;; It was later rewritten by rms. Some ideas were due to Masanobu. Grand | |
be820e8d NR |
29 | ;; Unification (sdb/dbx support) by Eric S. Raymond <esr@thyrsus.com> Barry |
30 | ;; Warsaw <bwarsaw@cen.com> hacked the mode to use comint.el. Shane Hartman | |
31 | ;; <shane@spr.com> added support for xdb (HPUX debugger). Rick Sladkey | |
32 | ;; <jrs@world.std.com> wrote the GDB command completion code. Dave Love | |
33 | ;; <d.love@dl.ac.uk> added the IRIX kluge, re-implemented the Mips-ish variant | |
34 | ;; and added a menu. Brian D. Carlstrom <bdc@ai.mit.edu> combined the IRIX | |
35 | ;; kluge with the gud-xdb-directories hack producing gud-dbx-directories. | |
36 | ;; Derek L. Davies <ddavies@world.std.com> added support for jdb (Java | |
37 | ;; debugger.) | |

1671 | ;; INVOCATION NOTES: | |
1672 | ;; | |
1673 | ;; You invoke jdb-mode with: | |
1674 | ;; | |
1675 | ;; M-x jdb <enter> | |
1676 | ;; | |
1677 | ;; It responds with: | |
1678 | ;; | |
1679 | ;; Run jdb (like this): jdb | |
1680 | ;; | |
1681 | ;; type any jdb switches followed by the name of the class you'd like to debug. | |
1682 | ;; Supply a fully qualfied classname (these do not have the ".class" extension) | |
1683 | ;; for the name of the class to debug (e.g. "COM.the-kind.ddavies.CoolClass"). | |
1684 | ;; See the known problems section below for restrictions when specifying jdb | |
1685 | ;; command line switches (search forward for '-classpath'). | |
1686 | ;; | |
1687 | ;; You should see something like the following: | |
1688 | ;; | |
1689 | ;; Current directory is ~/src/java/hello/ | |
1690 | ;; Initializing jdb... | |
1691 | ;; 0xed2f6628:class(hello) | |
1692 | ;; > | |
1693 | ;; | |
1694 | ;; To set an initial breakpoint try: | |
1695 | ;; | |
1696 | ;; > stop in hello.main | |
1697 | ;; Breakpoint set in hello.main | |
1698 | ;; > | |
1699 | ;; | |
1700 | ;; To execute the program type: | |
1701 | ;; | |
1702 | ;; > run | |
1703 | ;; run hello | |
1704 | ;; | |
1705 | ;; Breakpoint hit: running ... | |
1706 | ;; hello.main (hello:12) | |
1707 | ;; | |
1708 | ;; Type M-n to step over the current line and M-s to step into it. That, | |
1709 | ;; along with the JDB 'help' command should get you started. The 'quit' | |
1710 | ;; JDB command will get out out of the debugger. There is some truly | |
1711 | ;; pathetic JDB documentation available at: | |
1712 | ;; | |
1713 | ;; http://java.sun.com/products/jdk/1.1/debugging/ | |
1714 | ;; | |
1715 | ;; KNOWN PROBLEMS AND FIXME's: | |
1716 | ;; | |
1717 | ;; Not sure what happens with inner classes ... haven't tried them. | |
1718 | ;; | |
1719 | ;; Does not grok UNICODE id's. Only ASCII id's are supported. | |
1720 | ;; | |
1721 | ;; You must not put whitespace between "-classpath" and the path to | |
1722 | ;; search for java classes even though it is required when invoking jdb | |
1723 | ;; from the command line. See gud-jdb-massage-args for details. | |
1724 | ;; The same applies for "-sourcepath". | |
1725 | ;; | |
1726 | ;; Note: The following applies only if `gud-jdb-use-classpath' is nil; | |
1727 | ;; refer to the documentation of `gud-jdb-use-classpath' and | |
1728 | ;; `gud-jdb-classpath',`gud-jdb-sourcepath' variables for information | |
1729 | ;; on using the classpath for locating java source files. | |
1730 | ;; | |
1731 | ;; If any of the source files in the directories listed in | |
1732 | ;; gud-jdb-directories won't parse you'll have problems. Make sure | |
1733 | ;; every file ending in ".java" in these directories parses without error. | |
1734 | ;; | |
1735 | ;; All the .java files in the directories in gud-jdb-directories are | |
1736 | ;; syntactically analyzed each time gud jdb is invoked. It would be | |
1737 | ;; nice to keep as much information as possible between runs. It would | |
1738 | ;; be really nice to analyze the files only as neccessary (when the | |
1739 | ;; source needs to be displayed.) I'm not sure to what extent the former | |
1740 | ;; can be accomplished and I'm not sure the latter can be done at all | |
1741 | ;; since I don't know of any general way to tell which .class files are | |
1742 | ;; defined by which .java file without analyzing all the .java files. | |
1743 | ;; If anyone knows why JavaSoft didn't put the source file names in | |
1744 | ;; debuggable .class files please clue me in so I find something else | |

2341 | ;; | |
2342 | ;; If the buffer looks like this: | |
2343 | ;; -------------------- | |
2344 | ;; (gdb) set args foo bar | |
2345 | ;; (gdb) -!- | |
2346 | ;; -------------------- | |
2347 | ;; (the -!- marks the location of point), and we type `C-x SPC' in a | |
2348 | ;; source file to set a breakpoint, we want the buffer to end up like | |
2349 | ;; this: | |
2350 | ;; -------------------- | |
2351 | ;; (gdb) set args foo bar | |
2352 | ;; Breakpoint 1 at 0x92: file make-docfile.c, line 49. | |
2353 | ;; (gdb) -!- | |
2354 | ;; -------------------- | |
2355 | ;; Essentially, the old prompt is deleted, and the command's output | |
2356 | ;; and the new prompt take its place. | |
2357 | ;; | |
2358 | ;; Not echoing the command is easy enough; you send it directly using | |
2359 | ;; process-send-string, and it never enters the buffer. However, | |
2360 | ;; getting rid of the old prompt is trickier; you don't want to do it | |
2361 | ;; when you send the command, since that will result in an annoying | |
2362 | ;; flicker as the prompt is deleted, redisplay occurs while Emacs | |
2363 | ;; waits for a response from the debugger, and the new prompt is | |
2364 | ;; inserted. Instead, we'll wait until we actually get some output | |
2365 | ;; from the subprocess before we delete the prompt. If the command | |
2366 | ;; produced no output other than a new prompt, that prompt will most | |
2367 | ;; likely be in the first chunk of output received, so we will delete | |
2368 | ;; the prompt and then replace it with an identical one. If the | |
2369 | ;; command produces output, the prompt is moving anyway, so the | |
2370 | ;; flicker won't be annoying. | |
2371 | ;; | |
2372 | ;; So - when we want to delete the prompt upon receipt of the next | |
2373 | ;; chunk of debugger output, we position gud-delete-prompt-marker at | |
2374 | ;; the start of the prompt; the process filter will notice this, and | |
2375 | ;; delete all text between it and the process output marker. If | |

2386 | You start it up with one of the commands M-x gdb, M-x sdb, M-x dbx, | |
2387 | M-x perldb, M-x xdb, or M-x jdb. Each entry point finishes by executing a | |
2388 | hook; `gdb-mode-hook', `sdb-mode-hook', `dbx-mode-hook', | |
2389 | `perldb-mode-hook', `xdb-mode-hook', or `jdb-mode-hook' respectively. | |
2390 | ||
2391 | After startup, the following commands are available in both the GUD | |
2392 | interaction buffer and any source buffer GUD visits due to a breakpoint stop | |
2393 | or step operation: | |
2394 | ||
2395 | \\[gud-break] sets a breakpoint at the current file and line. In the | |
2396 | GUD buffer, the current file and line are those of the last breakpoint or | |
2397 | step. In a source buffer, they are the buffer's file and current line. | |
2398 | ||
2399 | \\[gud-remove] removes breakpoints on the current file and line. | |
2400 | ||
2401 | \\[gud-refresh] displays in the source window the last line referred to | |
2402 | in the gud buffer. | |
2403 | ||
2404 | \\[gud-step], \\[gud-next], and \\[gud-stepi] do a step-one-line, | |
2405 | step-one-line (not entering function calls), and step-one-instruction | |
2406 | and then update the source window with the current file and position. | |
2407 | \\[gud-cont] continues execution. | |
2408 | ||
2409 | \\[gud-print] tries to find the largest C lvalue or function-call expression | |
2410 | around point, and sends it to the debugger for value display. | |
2411 | ||
2412 | The above commands are common to all supported debuggers except xdb which | |
2413 | does not support stepping instructions. | |
2414 | ||
2415 | Under gdb, sdb and xdb, \\[gud-tbreak] behaves exactly like \\[gud-break], | |
2416 | except that the breakpoint is temporary; that is, it is removed when | |
2417 | execution stops on it. | |
2418 | ||
2419 | Under gdb, dbx, and xdb, \\[gud-up] pops up through an enclosing stack | |
2420 | frame. \\[gud-down] drops back down through one. | |
2421 | ||
2422 | If you are using gdb or xdb, \\[gud-finish] runs execution to the return from | |
2423 | the current function and stops. | |
2424 | ||
2425 | All the keystrokes above are accessible in the GUD buffer | |
2426 | with the prefix C-c, and in all buffers through the prefix C-x C-a. | |

2429 | themselves the appropriate number of times if you give a prefix | |
2430 | argument. | |
