;; 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>
|
|
|
|
|
|
;; The overloading code was then rewritten by Barry Warsaw <bwarsaw@cen.com>,
|
|
|
|
|
|
;; who also 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.)

|
|
|
|
|
|
;;
|
|
|
|
|
|
;; 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:

The list of directories to search is the value of `gud-jdb-classpath'.

The file pathname is obtained by converting the fully qualified

it to `gud-jdb-classpath' element by element until a match is found.

This method has a significant jdb startup time reduction advantage

since it does not require the scanning of all `gud-jdb-directories'

|
|
|
|
|
;; 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
|
|
|
|
|
|
;; flicker as the prompt is deleted, redisplay occurs while Emacs
|
|
|
|
|
|
;; waits for a response from the debugger, and the new prompt is
|
|
|
|
|
|
;; inserted. Instead, we'll wait until we actually get some output
|
|
|
|
|
|
;; from the subprocess before we delete the prompt. If the command
|
|
|
|
|
|
;; produced no output other than a new prompt, that prompt will most
|
|
|
|
|
|
;; likely be in the first chunk of output received, so we will delete
|
|
|
|
|
|
;; the prompt and then replace it with an identical one. If the
|
|
|
|
|
|
;; command produces output, the prompt is moving anyway, so the
|
|
|
|
|
|
;; flicker won't be annoying.

|

|
|
|
;; delete all text between it and the process output marker. If
|

"Major mode for interacting with an inferior debugger process.

You start it up with one of the commands M-x gdb, M-x sdb, M-x dbx,
|
|
|
|
|
|
M-x perldb, M-x xdb, or M-x jdb. Each entry point finishes by executing a
|
|
|
|
|
|
hook; `gdb-mode-hook', `sdb-mode-hook', `dbx-mode-hook',
|
|
|
|
|
|
`perldb-mode-hook', `xdb-mode-hook', or `jdb-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, and xdb, \\[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.
|
|
|
|
|
|
|

|

You may use the `gud-def' macro in the initialization hook to define other

|
commands.
