IPython pdb

https://travis-ci.org/gotcha/ipdb.png?branch=master

Use

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 python 2 scripts like

$ bin/ipdb mymodule.py

And for python 3

$ bin/ipdb3 mymodule.py

Alternatively with Python 2.7 only, you can also use

$ python -m ipdb mymodule.py

You can also enclose code with the with statement to launch ipdb if an exception is raised:

from ipdb import launch_ipdb_on_exception

with launch_ipdb_on_exception():
    [...]

Warning

Context managers were introduced in Python 2.5. Adding a context manager implies dropping Python 2.4 support. Use ipdb==0.6 with 2.4.

Warning

Using from future import print_function for Python 3 compat implies dropping Python 2.5 support. Use ipdb<=0.8 with 2.5.

Development

ipdb source code and tracker are at https://github.com/gotcha/ipdb.

Pull requests should take care of updating the changelog HISTORY.txt.

Third-party support

Products.PDBDebugMode

Zope2 Products.PDBDebugMode uses ipdb, if available, in place of pdb.

iw.debug

iw.debug allows you to trigger an ipdb debugger on any published object of a Zope2 application.

ipdbplugin

ipdbplugin is a nose test runner plugin that also uses the IPython debugger instead of pdb. (It does not depend on ipdb anymore).
