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.) |

1449 | ;; INVOCATION NOTES: | |
1450 | ;; | |
1451 | ;; You invoke jdb-mode with: | |
1452 | ;; | |
1453 | ;; M-x jdb <enter> | |
1454 | ;; | |
1455 | ;; It responds with: | |
1456 | ;; | |
f4b643a1 | 1457 | ;; Run jdb (like this): jdb |
c3fd0eea RS |
1458 | ;; |
1459 | ;; type any jdb switches followed by the name of the class you'd like to debug. | |
1460 | ;; Supply a fully qualfied classname (these do not have the ".class" extension) | |
1461 | ;; for the name of the class to debug (e.g. "COM.the-kind.ddavies.CoolClass"). | |
1462 | ;; See the known problems section below for restrictions when specifying jdb | |
1463 | ;; command line switches (search forward for '-classpath'). | |
1464 | ;; | |
1465 | ;; You should see something like the following: | |
1466 | ;; | |
1467 | ;; Current directory is ~/src/java/hello/ | |
1468 | ;; Initializing jdb... | |
1469 | ;; 0xed2f6628:class(hello) | |
1470 | ;; > | |
1471 | ;; | |
1472 | ;; To set an initial breakpoint try: | |
1473 | ;; | |
1474 | ;; > stop in hello.main | |
1475 | ;; Breakpoint set in hello.main | |
1476 | ;; > | |
1477 | ;; | |
1478 | ;; To execute the program type: | |
1479 | ;; | |
1480 | ;; > run | |
f4b643a1 | 1481 | ;; run hello |
c3fd0eea RS |
1482 | ;; |
1483 | ;; Breakpoint hit: running ... | |
1484 | ;; hello.main (hello:12) | |
1485 | ;; | |
1486 | ;; Type M-n to step over the current line and M-s to step into it. That, | |
1487 | ;; along with the JDB 'help' command should get you started. The 'quit' | |
35dd3c55 KH |

1494 | ;; | |
35dd3c55 | 1495 | ;; Not sure what happens with inner classes ... haven't tried them. |
c3fd0eea | 1496 | ;; |

1499 | ;; You must not put whitespace between "-classpath" and the path to |
1500 | ;; search for java classes even though it is required when invoking jdb | |
1501 | ;; from the command line. See gud-jdb-massage-args for details. | |
e78e1cd1 | 1502 | ;; The same applies for "-sourcepath". |
c3fd0eea | 1503 | ;; |
2ef4e909 RS |
1504 | ;; Note: The following applies only if `gud-jdb-use-classpath' is nil; |
1505 | ;; refer to the documentation of `gud-jdb-use-classpath' and | |
e78e1cd1 EZ |
1506 | ;; `gud-jdb-classpath',`gud-jdb-sourcepath' variables for information |
1507 | ;; on using the classpath for locating java source files. | |
2ef4e909 | 1508 | ;; |
35dd3c55 KH |
1509 | ;; If any of the source files in the directories listed in |
1510 | ;; gud-jdb-directories won't parse you'll have problems. Make sure | |
1511 | ;; every file ending in ".java" in these directories parses without error. | |
1512 | ;; | |
1513 | ;; All the .java files in the directories in gud-jdb-directories are | |
c6094cae | 1514 | ;; syntactically analyzed each time gud jdb is invoked. It would be |
35dd3c55 KH |
1515 | ;; nice to keep as much information as possible between runs. It would |
1516 | ;; be really nice to analyze the files only as neccessary (when the | |
1517 | ;; source needs to be displayed.) I'm not sure to what extent the former | |
1518 | ;; can be accomplished and I'm not sure the latter can be done at all | |
1519 | ;; since I don't know of any general way to tell which .class files are | |
1520 | ;; defined by which .java file without analyzing all the .java files. | |
1521 | ;; If anyone knows why JavaSoft didn't put the source file names in | |
1522 | ;; debuggable .class files please clue me in so I find something else | |

2136 | ;; -------------------- | |

2138 | ;; and the new prompt take its place. | |
2139 | ;; | |
2140 | ;; Not echoing the command is easy enough; you send it directly using | |
2141 | ;; process-send-string, and it never enters the buffer. However, | |
2142 | ;; getting rid of the old prompt is trickier; you don't want to do it | |
2143 | ;; when you send the command, since that will result in an annoying | |
2144 | ;; flicker as the prompt is deleted, redisplay occurs while Emacs | |
2145 | ;; waits for a response from the debugger, and the new prompt is | |
2146 | ;; inserted. Instead, we'll wait until we actually get some output | |
2147 | ;; from the subprocess before we delete the prompt. If the command | |
2148 | ;; produced no output other than a new prompt, that prompt will most | |
2149 | ;; likely be in the first chunk of output received, so we will delete | |
2150 | ;; the prompt and then replace it with an identical one. If the | |
2151 | ;; command produces output, the prompt is moving anyway, so the | |
2152 | ;; flicker won't be annoying. | |
2153 | ;; | |
2154 | ;; So - when we want to delete the prompt upon receipt of the next | |
2155 | ;; chunk of debugger output, we position gud-delete-prompt-marker at | |
2156 | ;; the start of the prompt; the process filter will notice this, and | |

2ef4e909 | 2169 | M-x perldb, M-x xdb, or M-x jdb. Each entry point finishes by executing a |

2173 | After startup, the following commands are available in both the GUD |
2174 | interaction buffer and any source buffer GUD visits due to a breakpoint stop | |
2175 | or step operation: | |
13b80a60 | 2176 | |
ee0155df ER |
2177 | \\[gud-break] sets a breakpoint at the current file and line. In the |
2178 | GUD buffer, the current file and line are those of the last breakpoint or | |
2179 | step. In a source buffer, they are the buffer's file and current line. | |
2180 | ||
45025813 ER |
2181 | \\[gud-remove] removes breakpoints on the current file and line. |
2182 | ||
ee0155df | 2183 | \\[gud-refresh] displays in the source window the last line referred to |
24d725c2 | 2184 | in the gud buffer. |
13b80a60 | 2185 | |
ee0155df ER |
2186 | \\[gud-step], \\[gud-next], and \\[gud-stepi] do a step-one-line, |
2187 | step-one-line (not entering function calls), and step-one-instruction | |
2188 | and then update the source window with the current file and position. | |
2189 | \\[gud-cont] continues execution. | |
13b80a60 | 2190 | |
ee0155df ER |
2191 | \\[gud-print] tries to find the largest C lvalue or function-call expression |
2192 | around point, and sends it to the debugger for value display. | |
24d725c2 | 2193 | |
6496f3d2 RS |
2194 | The above commands are common to all supported debuggers except xdb which |
2195 | does not support stepping instructions. | |
24d725c2 | 2196 | |
6496f3d2 | 2197 | Under gdb, sdb and xdb, \\[gud-tbreak] behaves exactly like \\[gud-break], |
ee0155df ER |
2198 | except that the breakpoint is temporary; that is, it is removed when |
2199 | execution stops on it. | |
24d725c2 | 2200 | |
6496f3d2 | 2201 | Under gdb, dbx, and xdb, \\[gud-up] pops up through an enclosing stack |
c6094cae | 2202 | frame. \\[gud-down] drops back down through one. |
24d725c2 | 2203 | |
6496f3d2 | 2204 | If you are using gdb or xdb, \\[gud-finish] runs execution to the return from |
ee0155df | 2205 | the current function and stops. |
