ipdb exports functions to access the IPython debugger, which features tab completion, syntax highlighting, better tracebacks, better introspection with the same interface as the pdb module.
Example usage:
import ipdb
ipdb.set_trace()
ipdb.pm()
ipdb.run('x[0] = 3')
result = ipdb.runcall(function, arg0, arg1, kwarg='foo')
result = ipdb.runeval('f(1,2) - 3')
The post-mortem function, ipdb.pm(), is equivalent to the magic function
%debug.
If you install ipdb with a tool which supports setuptools entry points,
an ipdb script is made for you. You can use it to debug your scripts like
$ bin/ipdb mymodule.py
With Python 2.7 only, you can also use
$ python -m ipdb mymodule.py
ipdb source code and tracker are at https://github.com/gotcha/ipdb.
Zope2 Products.PDBDebugMode uses ipdb, if available, in place of pdb.
iw.debug allows you to trigger an ipdb debugger on any published object
of a Zope2 application.
ipdbplugin is a nose test runner plugin that also uses the IPython debugger
instead of pdb. (It does not depend on ipdb anymore).
