===========
Debugging
===========
Some options are:
Run in ipython
--------------
As in::
In [1]: run mymodule.py
... (somecrash)
In [2]: %debug
Then diagnose, using the workspace that comes up, which has the
context of the crash.
You can also do::
In [1] %pdb on
In [2]: run mymodule.py
... (somecrash)
At that point you will be automatically dropped into the the workspace
in the context of the error. This is very similar to the matlab
``dbstop if error`` command.
See the `ipython manual`_ , and
`debugging in ipython <http://ipython.scipy.org/doc/manual/html/interactive/reference.html#using-the-python-debugger-pdb>`_
for more detail.
Embed ipython in crashing code
------------------------------
Often it is not possible to run the code directly from ipython using
the ``run`` command. For example, the code may be called from some
other system such as sphinx_. In that case you can embed. At the
point that you want ipython to open with the context available for
instrospection, add::
from IPython.Shell import IPShellEmbed
ipshell = IPShellEmbed()
ipshell()
See
`embedding ipython <http://ipython.scipy.org/doc/manual/html/interactive/reference.html#embedding-ipython>`_
for more detail.
