| 27 | ||
| 13b80a60 | 28 | ;; The ancestral gdb.el was by W. Schelter <wfs@rascal.ics.utexas.edu> |
| 24d725c2 | 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 |
| 3b3703fa | 36 | ;; a menu. Brian D. Carlstrom <bdc@ai.mit.edu> combined the IRIX kluge with |
| c3fd0eea RS |
37 | ;; the gud-xdb-directories hack producing gud-dbx-directories. Derek L. Davies |
| 38 | ;; <ddavies@world.std.com> added support for jdb (Java debugger.) | |

| 1279 | ;; | |
| 1280 | ;; INVOCATION NOTES: | |
| 1281 | ;; | |
| 1282 | ;; You invoke jdb-mode with: | |
| 1283 | ;; | |
| 1284 | ;; M-x jdb <enter> | |
| 1285 | ;; | |
| 1286 | ;; It responds with: | |
| 1287 | ;; | |
| 1288 | ;; Run jdb (like this): jdb | |
| 1289 | ;; | |
| 1290 | ;; type any jdb switches followed by the name of the class you'd like to debug. | |
| 1291 | ;; Supply a fully qualfied classname (these do not have the ".class" extension) | |
| 1292 | ;; for the name of the class to debug (e.g. "COM.the-kind.ddavies.CoolClass"). | |
| 1293 | ;; See the known problems section below for restrictions when specifying jdb | |
| 1294 | ;; command line switches (search forward for '-classpath'). | |
| 1295 | ;; | |
| 1296 | ;; You should see something like the following: | |
| 1297 | ;; | |
| 1298 | ;; Current directory is ~/src/java/hello/ | |
| 1299 | ;; Initializing jdb... | |
| 1300 | ;; 0xed2f6628:class(hello) | |
| 1301 | ;; > | |
| 1302 | ;; | |
| 1303 | ;; To set an initial breakpoint try: | |
| 1304 | ;; | |
| 1305 | ;; > stop in hello.main | |
| 1306 | ;; Breakpoint set in hello.main | |
| 1307 | ;; > | |
| 1308 | ;; | |
| 1309 | ;; To execute the program type: | |
| 1310 | ;; | |
| 1311 | ;; > run | |
| 1312 | ;; run hello | |
| 1313 | ;; | |
| 1314 | ;; Breakpoint hit: running ... | |
| 1315 | ;; hello.main (hello:12) | |
| 1316 | ;; | |
| 1317 | ;; Type M-n to step over the current line and M-s to step into it. That, | |
| 1318 | ;; along with the JDB 'help' command should get you started. The 'quit' | |
| 35dd3c55 KH |

| 1325 | ;; | |
| 35dd3c55 | 1326 | ;; Not sure what happens with inner classes ... haven't tried them. |
| c3fd0eea RS |
1327 | ;; |
| 1328 | ;; Does not grok UNICODE id's. Only ASCII id's are supported. | |
| 1329 | ;; | |
| c3fd0eea RS |
1330 | ;; You must not put whitespace between "-classpath" and the path to |
| 1331 | ;; search for java classes even though it is required when invoking jdb | |
| 1332 | ;; from the command line. See gud-jdb-massage-args for details. | |
| 1333 | ;; | |
| 35dd3c55 KH |
1334 | ;; If any of the source files in the directories listed in |
| 1335 | ;; gud-jdb-directories won't parse you'll have problems. Make sure | |
| 1336 | ;; every file ending in ".java" in these directories parses without error. | |
| 1337 | ;; | |
| 1338 | ;; All the .java files in the directories in gud-jdb-directories are | |
| 1339 | ;; syntactically analyzed each time gud jdb is invoked. It would be | |
| 1340 | ;; nice to keep as much information as possible between runs. It would | |
| 1341 | ;; be really nice to analyze the files only as neccessary (when the | |
| 1342 | ;; source needs to be displayed.) I'm not sure to what extent the former | |
| 1343 | ;; can be accomplished and I'm not sure the latter can be done at all | |
| 1344 | ;; since I don't know of any general way to tell which .class files are | |
| 1345 | ;; defined by which .java file without analyzing all the .java files. | |
| 1346 | ;; If anyone knows why JavaSoft didn't put the source file names in | |
| 1347 | ;; debuggable .class files please clue me in so I find something else | |
| 1348 | ;; to be spiteful and bitter about. | |

| 1779 | ;;; flicker as the prompt is deleted, redisplay occurs while Emacs | |
| 1780 | ;;; waits for a response from the debugger, and the new prompt is | |
| 1781 | ;;; inserted. Instead, we'll wait until we actually get some output | |
| 1782 | ;;; from the subprocess before we delete the prompt. If the command | |

1808 | After startup, the following commands are available in both the GUD |
| 1809 | interaction buffer and any source buffer GUD visits due to a breakpoint stop | |
| 1810 | or step operation: | |
| 13b80a60 | 1811 | |
| ee0155df ER |
1812 | \\[gud-break] sets a breakpoint at the current file and line. In the |
| 1813 | GUD buffer, the current file and line are those of the last breakpoint or | |
| 1814 | step. In a source buffer, they are the buffer's file and current line. | |
| 1815 | ||
| 45025813 ER |
1816 | \\[gud-remove] removes breakpoints on the current file and line. |
| 1817 | ||
| ee0155df | 1818 | \\[gud-refresh] displays in the source window the last line referred to |
| 24d725c2 | 1819 | in the gud buffer. |
| 13b80a60 | 1820 | |
| ee0155df ER |
1821 | \\[gud-step], \\[gud-next], and \\[gud-stepi] do a step-one-line, |
| 1822 | step-one-line (not entering function calls), and step-one-instruction | |
| 1823 | and then update the source window with the current file and position. | |
| 1824 | \\[gud-cont] continues execution. | |
| 13b80a60 | 1825 | |
| ee0155df ER |
1826 | \\[gud-print] tries to find the largest C lvalue or function-call expression |
| 1827 | around point, and sends it to the debugger for value display. | |
| 24d725c2 | 1828 | |
| 6496f3d2 RS |
1829 | The above commands are common to all supported debuggers except xdb which |
| 1830 | does not support stepping instructions. | |
| 24d725c2 | 1831 | |
| 6496f3d2 | 1832 | Under gdb, sdb and xdb, \\[gud-tbreak] behaves exactly like \\[gud-break], |
| ee0155df ER |
1833 | except that the breakpoint is temporary; that is, it is removed when |
| 1834 | execution stops on it. | |
| 24d725c2 | 1835 | |
| 6496f3d2 | 1836 | Under gdb, dbx, and xdb, \\[gud-up] pops up through an enclosing stack |
| ee0155df | 1837 | frame. \\[gud-down] drops back down through one. |
| 24d725c2 | 1838 | |
| 6496f3d2 | 1839 | If you are using gdb or xdb, \\[gud-finish] runs execution to the return from |
| ee0155df | 1840 | the current function and stops. |
| 24d725c2 | 1841 | |

1842 | All the keystrokes above are accessible in the GUD buffer |
| 1843 | with the prefix C-c, and in all buffers through the prefix C-x C-a. | |

| ee0155df ER |
