Custom magic command

[kangwonlee]

Motivation

• Wouldn't it be nice if we can include some C/C++ source codes in the ipython notebook files?
• Similar to %%cython
• Let's call it %%cpp
• Build options as command line option

Need more info

• How to set compiler command line options?

How to write a magic command?

• https://ipython.readthedocs.io/en/stable/config/custommagics.html
• https://stackoverflow.com/questions/10361206/how-to-run-an-ipython-magic-from-a-script-or-timing-a-python-script
• What if includes bash commands?

How to make it easy to deploy?

• So that a user does not have to build the whole jupyter notebook?
• According to kmario23, one could try a custom magic using following command

$ python setup.py develop 

How to test the magic command?

• Fork https://github.com/jupyter/notebook?
• Preparing for a package and using setuptools would enable testing, hopefully easily.
• https://pmbaumgartner.github.io/blog/testing-ipython-magics/

Where to put the custom magic command?

• As a subtree of a different repository?
• within a .ipynb file under a subfolder may add the path as follows?

import os
import sys

sys.path.append(
    os.path.abspath(
        os.path.join(os.path.dirname(__file__), os.pardir, <custom magic>)
    )
)

• setuptools would deal with this problem too
