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

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).
