pdb with emacs

[Yuri Shtil]

Hi,

I am trying to learn python and use the gud/pdb from emacs. The
functionality that I am used to under gud/gdb and gud/perldb is missing, or
I don't know how to make it work.
Specifically: when I start pdb on a script file, the source does not show in
an another window as it does with perldb and gdb. If I bring it up in an
another window,
the ^X SPC set a break, but the subsequent gud-next commands do not move the
execution cursor in the source file window.

Any help will be greatly appreciated.

Your source will show up when you step into your program, e.g. by
doing an "S" pdb command.

I never use gud's commands while in pdb mode because they didn't work
- at least not as I expected - and I've already been familiar with pdb
syntax. You'd better use pdb commands in its debugger window.

The source appears for me if I do C-c C-s immediately after startup.

I can in general set breakpoints using C-x SPC in the source buffer
after the source appears, which will be hit after I resume
execution. So I guess I don't observe your problems. I am using a
custom "pdb" executable script though, maybe this helps:

#!/bin/sh
exec python $HOME/opt/python-2.3/lib/python2.3/pdb.py "$@"
