Use IPython magic functions in ipdb shell

Question

When debugging Python script using ipdb my_script.py, I want to use IPython magic functions like %paste, %cd in ipdb debug session shell. Is is possible and how?

Answer 1

According to the ipdb Github repo magic IPython functions are not available. Fortunately, the IPython debugger provides a couple of clues of how to get this functionality without launching a separate IPython shell.

Here is what I did to run %cpaste:

ipdb> from IPython import get_ipython ipdb> shell = get_ipython() ipdb> shell.find_line_magic('cpaste')() Pasting code; enter '--' alone on the line to stop or use Ctrl-D. :for i in range(0,5): :       print i :-- 0 1 2 3 4 

This way, you can step through your code and have access to all the IPython magic functions via the method find_line_magic(your_magic_function).

Answer 2

You can open a IPython shell inside a stack, just like pdb does. Do the following:

• Import embed() from IPython, and put it inside your code.
• Run the script

Example:

from IPython import embed  def some_func():     i = 0     embed()     return 0 

In Python shell:

>>> te.func()  IPython 1.0.0 -- An enhanced Interactive Python. (...)  In [1]: %whos  Variable   Type    Data/Info i          int     0  In [2]:
