jupystar

Convert Jupyter notebooks (ipynb) to Starboard notebooks.

It won't work for all notebooks - but should at least give sensible output that can be adapted easily.

Implementation details

nbformat (Jupyter's ipynb format) V3 is supported - when Jupystar detects a V3 file it converts it to a V4 format prior to conversion to a Starboard notebook. Some details of this conversion:

• The first worksheet is used, all others are ignored. Also, worksheet metadata is ignored. Worksheets aren't really a thing anymore anyway.
• All output is currently dropped in conversion from v3 to v4.

LaTeX conversion

Starboard notebook uses KaTeX to display math, which doesn't support the same functionality as MathJax (used in Jupyter).

• We perform a string replacement for some tags.
• Equations inside of markdown that are only delimited by \begin{<environment>} and \end{<environment>} get enclosed in $$ tags.
