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:

.. code-block:: python

    import ipdb
    ipdb.set_trace(context=5)  # will show five lines of code
                               # instead of the default three lines
    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.

.. _IPython: http://ipython.org

an ipdb script is made for you. You can use it to debug your python 2 scripts like
b” 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:

.. code-block:: python

    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.

Issues with stdout

Some tools, like nose fiddle with stdout.

Until ipdb==0.9.4, we tried to guess when we should also fiddle with stdout to support those tools. However, all strategies tried until 0.9.4 have proven brittle.

If you use nose or another tool that fiddles with stdout, you should explicitely ask for stdout fiddling by using ipdb like this

.. code-block:: python

    import ipdb

    from ipdb import slaunch_ipdb_on_exception
    with slaunch_ipdb_on_exception():

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.

.. _Products.PDBDebugMode: http://pypi.python.org/pypi/Products.PDBDebugMode

iw.debug ++++++++

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

.. _iw.debug: http://pypi.python.org/pypi/iw.debug

ipdbplugin ++++++++++

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

.. _ipdbplugin: http://pypi.python.org/pypi/ipdbplugin .. _nose: http://readthedocs.org/docs/nose
