You emacs inhabitants out there may be interested in pdbtrack.el, a little alternative for source-file python debugging in emacs: http://www.zope.org/Wikis/klm/PDBTrack With pdbtrack, whenever you run pdb, emacs tracks (*) the current source file line, centered in another emacs window. It keys on the process output, cuing on the stack trace format and the pdb prompt, so it's pretty unlikely to misfire. That's all it does - it lacks a lot of GUD features, like putting highlighting glyphs on the current line, providing debugging commands from inside the source file buffer, etc. On the other hand, it's also very trim, code-lines-wise - a total of 122 lines, without any GUD connection, and that includes 59 lines that are only for working around a bug in mainline emacs' make-local-hook. (Incorporating the GUD-style features may not be too hard - since it touches the buffer where the debugging was started, as well as the source file buffers, it could set up the necessary state and bindings per session. But i'm not particularly driven to pursue that - tracking the current line in the source file seems to be most of what i need...) The fundamental difference between pdbtrack and GUD/pdb.el is that pdbtrack doesn't require you to launch the debugging session from a particular buffer - it tracks from any comint buffers where you run python. This fits the way i tend to use the debugger - generally, i do more-or-less elaborate interactions with my application *before* i go into the debugger, to set up the context and/or explore my way to the debugging start point. With GUD i have to start the session directly in the debugger. And then, when i finish a GUD session, (i believe) the context is lost. When debugging in a regular shell buffer (and the python-mode py-shell, etc), i drop back into python, wander around, and often launch back into the debugger, with the accumulated state. pdbtrack tracks wherever and whenver you're running pdb in emacs. (I posted more description yesterday to the python and the zope lists: http://www.python.org/pipermail/python-list/2000-July/108654.html ) If this proves to be of general interest and acceptance, i'd love to see it considered for inclusion with python-mode...
