Following my thoughts yesterday, here are some VIM python scripts to add python breakpoint and debugging features to VIM. With this set up the F7 key will set a breakpoint on a line of code, Shift-F7 will remove all breakpoints and Shift-F12 will execute a script in the python debugger. This only runs on windows as far as I know, because it uses the 'start' command to launch the debugger in a seperate process without VIM waiting for it to finish. This allows you to look through the source code (and fix it) while the debugging is still in progress.

Tired of debugging Python using print statements? Don't like the cumbersome PDB (Python debugger) console? Prefer using Vim for coding your Python programs? VimPdb is the solution - allows debugging Python in an IDE-fashion, right within the Vim editor.

I use Decho; its an instrumented-code type of debugging tool. You can get the Decho plugin from: http://vim.sourceforge.net/scripts/script.php?script_id=120 -or- http://mysite.verizon.net/astronaut/vim/index.html#DECHO (this latter one is always the most up-to-date) To install if you're using vim7.1: 1. Install a new version of Decho: vim Decho.vba.gz :so % :q Regards, Chip Campbell

Clewn implements full gdb support in the vim editor: breakpoints, watch variables, gdb command completion, assembly windows, etc.

Pyclewn is a python program that allows the use of the vim editor as a front end to a debugger. Pyclewn currently supports the gdb debugger.

As I am sure you found out from Tony's post Vim has a built in debugger for Vim scripts. What I would suggest to you is to download and use this plugin by Hari: " BreakPts - Debug Vim Scripts " Author: Hari Krishna Dara " http://www.vim.org/scripts/script.php?script_id=618 I use it regularly and love it.
