How can I make ipdb show more lines of context while debugging?

Question

By default, during debugging in IPython, ipdb shows one line above and one line below the current position in code.

Is there an easy way to make the area shown a bit b

Answer 1

You can get more context by doing:

ipdb.set_trace(context=21)

(there's a bug introduced in 0.10.0 that breaks this, but it should be fixed soon)

Permanent context size

To permanently set context size, find the installation directory by doing

python -c 'import ipdb; print(ipdb)'

which will show you a __init__.py file. Open that file and find the line (which may also be found in IPDB's __main__.py:

def set_trace(frame=None, context=3):

change the 3 to however many context lines you want.
