M-x pdb fails

[Andreas Roehler]

without prior setup from other sources,

M-x pdb foo.py

fails while proposing an unusable recipe

pdb foo.py

OTOH http://www.emacswiki.org/emacs/PdbNotes contains a recipe for setup

PdbNotes

For running python in GdbMode you need to set the pdb-path variable in .emacs or wherever.

The advice defaults to the current buffer name when invoking M-x pdb, and comes from here:

http://lists.gnu.org/archive/html/help-gnu-emacs/2003-10/msg00577.html

The rest worked automagically in 22.2.1

 ;;pdb setup, note the python version
 (setq pdb-path '/usr/lib/python2.5/pdb.py
       gud-pdb-command-name (symbol-name pdb-path))
 (defadvice pdb (before gud-query-cmdline activate)
   "Provide a better default command line when called interactively."
   (interactive
    (list (gud-query-cmdline pdb-path
        (file-name-nondirectory buffer-file-name)))))

;;;;;;;;;;;;;

IMO python-mode should do that setup by itself.
