nbdev

nbdev is a tool for exploratory programming and makes it possible to develop complex libraries using only Jupyter notebooks.

nb_export

I tend to write smaller scripts in my day to day work, so instead of setting up a comlete nbdev project I found following snippet more useful in this regard:

#| default_exp core

#|export
def foo(): pass

from nbdev.export import nb_export
nb_export('test.ipynb', '.')

Pasting and running those lines at the end of a notebook exports it as pure core.py file - removing the need to copy and paste between those files.

nbdev for subparts of a project

1. Create a settings.ini file (just one for the whole project/repo)

2. In your notebook file, add “#|default_exp module_name” in the very top cell of the notebook.

3. For every code cell that you want include in module_name.py, you should have “#| export” at the top.

Then you can run nbdev_export --path module_name.ipynb and it works! (i.e. module_name.py appears in the lib_name/ specified in settings.ini.)
