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

| ;; command definition |
| |
| ;; This macro is used below to define some basic debugger interface commands. |
| ;; Of course you may use `gud-def' with any other debugger command, including |
| ;; user defined ones. |
| |
| ;; A macro call like (gud-def FUNC CMD KEY DOC) expands to a form |
| ;; which defines FUNC to send the command CMD to the debugger, gives |
| ;; it the docstring DOC, and binds that function to KEY in the GUD |
| ;; major mode. The function is also bound in the global keymap with the |
| ;; GUD prefix. |
| |
| (defmacro gud-def (func cmd key &optional doc) |
| "Define FUNC to be a command sending CMD and bound to KEY, with |
| optional doc string DOC. Certain %-escapes in the string arguments |
| are interpreted specially if present. These are: |
| |
| %f -- Name (without directory) of current source file. |
| %F -- Name (without directory or extension) of current source file. |
| %d -- Directory of current source file. |
| %l -- Number of current source line. |
| %e -- Text of the C lvalue or function-call expression surrounding point. |
| %a -- Text of the hexadecimal address surrounding point. |
| %b -- Text of the most recently created breakpoint id. |
| %p -- Prefix argument to the command (if any) as a number. |
| %c -- Fully qualified class name derived from the expression |
| surrounding point (jdb only). |
| |
| The `current' source file is the file of the current buffer (if |
| we're in a C file) or the source file current at the last break or |
| step (if we're in the GUD buffer). |
| The `current' line is that of the current buffer (if we're in a |
| source file) or the source line number at the last break or step (if |
| we're in the GUD buffer)." |

| ;; |
| ;; The job of the massage-args method is to modify the given list of |
| ;; debugger arguments before running the debugger. |
| ;; |
| ;; The job of the marker-filter method is to detect file/line markers in |
| ;; strings and set the global gud-last-frame to indicate what display |
| ;; action (if any) should be triggered by the marker. Note that only |
| ;; whatever the method *returns* is displayed in the buffer; thus, you |
| ;; can filter the debugger's output, interpreting some and passing on |
| ;; the rest. |

| ;; JDB support. |
| ;; |
| ;; AUTHOR: Derek Davies <ddavies@world.std.com> |
| ;; Zoltan Kemenczy <zoltan@ieee.org;zkemenczy@rim.net> |
| ;; |
| ;; CREATED: Sun Feb 22 10:46:38 1998 Derek Davies. |
| ;; UPDATED: Nov 11, 2001 Zoltan Kemenczy |
| ;; Dec 10, 2002 Zoltan Kemenczy - added nested class support |
| ;; |
| ;; INVOCATION NOTES: |
| ;; |
| ;; You invoke jdb-mode with: |
| ;; |
| ;; M-x jdb <enter> |
| ;; |
| ;; It responds with: |
| ;; |
| ;; Run jdb (like this): jdb |
| ;; |
| ;; type any jdb switches followed by the name of the class you'd like to debug. |
| ;; Supply a fully qualfied classname (these do not have the ".class" extension) |
| ;; for the name of the class to debug (e.g. "COM.the-kind.ddavies.CoolClass"). |
| ;; See the known problems section below for restrictions when specifying jdb |
| ;; command line switches (search forward for '-classpath'). |
| ;; |
| ;; You should see something like the following: |
| ;; |
| ;; Current directory is ~/src/java/hello/ |
| ;; Initializing jdb... |
| ;; 0xed2f6628:class(hello) |
| ;; > |
| ;; |
| ;; To set an initial breakpoint try: |
| ;; |
| ;; > stop in hello.main |
| ;; Breakpoint set in hello.main |
| ;; > |
| ;; |
| ;; To execute the program type: |
| ;; |
| ;; > run |
| ;; run hello |
| ;; |
| ;; Breakpoint hit: running ... |
| ;; hello.main (hello:12) |
| ;; |
| ;; Type M-n to step over the current line and M-s to step into it. That, |
| ;; along with the JDB 'help' command should get you started. The 'quit' |
| ;; JDB command will get out out of the debugger. There is some truly |
| ;; pathetic JDB documentation available at: |
| ;; |
| ;; http://java.sun.com/products/jdk/1.1/debugging/ |
| ;; |
| ;; KNOWN PROBLEMS AND FIXME's: |
| ;; |
| ;; Not sure what happens with inner classes ... haven't tried them. |
| ;; |
| ;; Does not grok UNICODE id's. Only ASCII id's are supported. |
| ;; |
| ;; You must not put whitespace between "-classpath" and the path to |
| ;; search for java classes even though it is required when invoking jdb |
| ;; from the command line. See gud-jdb-massage-args for details. |
| ;; The same applies for "-sourcepath". |
| ;; |
| ;; Note: The following applies only if `gud-jdb-use-classpath' is nil; |
| ;; refer to the documentation of `gud-jdb-use-classpath' and |
| ;; `gud-jdb-classpath',`gud-jdb-sourcepath' variables for information |
| ;; on using the classpath for locating java source files. |
| ;; |
| ;; If any of the source files in the directories listed in |
| ;; gud-jdb-directories won't parse you'll have problems. Make sure |
| ;; every file ending in ".java" in these directories parses without error. |
| ;; |
| ;; All the .java files in the directories in gud-jdb-directories are |
| ;; syntactically analyzed each time gud jdb is invoked. It would be |
| ;; nice to keep as much information as possible between runs. It would |
| ;; be really nice to analyze the files only as neccessary (when the |
| ;; source needs to be displayed.) I'm not sure to what extent the former |
| ;; can be accomplished and I'm not sure the latter can be done at all |
| ;; since I don't know of any general way to tell which .class files are |
| ;; defined by which .java file without analyzing all the .java files. |
| ;; If anyone knows why JavaSoft didn't put the source file names in |
| ;; debuggable .class files please clue me in so I find something else |
| ;; to be spiteful and bitter about. |

| ;; getting rid of the old prompt is trickier; you don't want to do it |
| ;; when you send the command, since that will result in an annoying |

| |
| You start it up with one of the commands M-x gdb, M-x sdb, M-x dbx, |
| M-x perldb, M-x xdb, M-x jdb, or M-x lldb. Each entry point finishes by |
| executing a hook; `gdb-mode-hook', `sdb-mode-hook', `dbx-mode-hook', |
| `perldb-mode-hook', `xdb-mode-hook', `jdb-mode-hook', or `lldb-mode-hook' |
| respectively. |
| |
| After startup, the following commands are available in both the GUD |
| interaction buffer and any source buffer GUD visits due to a breakpoint stop |
| or step operation: |
| |
| \\[gud-break] sets a breakpoint at the current file and line. In the |
| GUD buffer, the current file and line are those of the last breakpoint or |
| step. In a source buffer, they are the buffer's file and current line. |
| |
| \\[gud-remove] removes breakpoints on the current file and line. |
| |
| \\[gud-refresh] displays in the source window the last line referred to |
| in the gud buffer. |
| |
| \\[gud-step], \\[gud-next], and \\[gud-stepi] do a step-one-line, |
| step-one-line (not entering function calls), and step-one-instruction |
| and then update the source window with the current file and position. |
| \\[gud-cont] continues execution. |
| |
| \\[gud-print] tries to find the largest C lvalue or function-call expression |
| around point, and sends it to the debugger for value display. |
| |
| The above commands are common to all supported debuggers except xdb which |
| does not support stepping instructions. |
| |
| Under gdb, sdb and xdb, \\[gud-tbreak] behaves exactly like \\[gud-break], |
| except that the breakpoint is temporary; that is, it is removed when |
| execution stops on it. |
| |
| Under gdb, dbx, xdb, and lldb, \\[gud-up] pops up through an enclosing stack |
| frame. \\[gud-down] drops back down through one. |
| |
| If you are using gdb or xdb, \\[gud-finish] runs execution to the return from |
| the current function and stops. |
| |
| All the keystrokes above are accessible in the GUD buffer |
| with the prefix C-c, and in all buffers through the prefix C-x C-a. |
| |
| All pre-defined functions for which the concept make sense repeat |
| themselves the appropriate number of times if you give a prefix |
| argument. |
