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.
import ipdb ipdb.set_trace() ipdb.pm() ipdb.run('x = 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(): [...]
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.
Using from future import print_function for Python 3 compat implies dropping Python 2.5 support. Use ipdb<=0.8 with 2.5.
ipdb source code and tracker are at https://github.com/gotcha/ipdb.
Pull requests should take care of updating the changelog HISTORY.txt.
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.
