This post explains why yesterday *might* turn out to be the second most
important day in Leo's history. More likely, export-jupyter-notebook will
turn out to be just another cool feature :-)
A day or so ago I remarked to Rebecca that for Leo to become truly popular
(hundreds of downloads a day), some "young hotshot" would have to talk up
Leo. Presumably he or she would be a well-connected "star" of some kind.
Better integration with Jupyter notebooks makes that scenario more likely.
One can imagine an eminent scientist using Leo to create at least the
documentation part ('markdown' nodes) of Jupyter notebooks.
It is actually quite clumsy to edit markdown nodes on the Jupyter web page:
- Change the node type from 'Markdown' to 'Raw NBConvert'.
- Make the changes.
- Change the note type back to 'Markdown'.
- Re-render the cell by clicking on the 'run cell, select below' icon.
Editing the node in Leo and exporting the entire .ipynb file might be
automated to be faster than this.
Furthermore, generating html headers automatically in Leo, *based on
outline level*, is a huge advantage. Just as with the rst3 command, one can
reorganize a tree of markdown nodes *without* changing html headers. And
of course, the tree instantly shows document structure, something that is
*impossible* in Jupyter notebooks.
*Summary*Leo could become wildly popular not because of what Jupyter
integration can do for *Leo's* users, but because of what Jupyter
integration can do for *IPython/Jupyter* users.
Having said that, Jupyter offers a huge amount to Leo, including superior
rendering. Imo, we must make it as easy as possible to render Leo outlines
using Jupyter. The export-jupyter-notebook command is the foundation for
these efforts.
Finally, Leo's viewrendered pane treats markdown as reStructuredText.
Supporting markdown fully suddenly has very high priority.
