Integration of IPython pdb

IPython pdb

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 scripts like

$ bin/ipdb mymodule.py

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.

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).
