The following are various thoughts about IPython that I had soon after returning from vacation. They seem relevant to the question about where Leo is going.
TL:DR: IPython doesn't need Leo's features. Leo *could* use IPython's typing completion. - IPython is a super successful project. Fernando Perez has gotten grants totaling millions of dollars. The design of the IPython core and the newly-separated Jupyter notebook <https://jupyter.org/> are brilliantly simple. - Adding outlining to IPython might not be a good idea. In any case, the IPython community will choose which enhancements make sense. - The Jupyter notebook takes the simplest possible view of literate programming. Notebooks can intersperse documentation cells with code cells. No LP-specific markup at all. No tangling, or rather, the documentation cells are automatically rendered. The disadvantage is that links are a bit clumsy to insert, and there is really no document-level organization, but this doesn't seem like a big drawback, because the example notebooks I've seen <http://nb.bianp.net/sort/views/> tend to be pretty short. You can quibble about these design choices, but the fact remains that the IPython/Jupyter notebook is very easy to understand. In short, IPython will do just fine without Leo. But Leo could be extended to handle .ipynb (Jupyter) files. That's on the list. More interestingly Leo *could *use IPython's scheme of basing code completion of live objects, provided users are willing to execute the code in an outline. Yes, this could be dangerous, and people must be aware of the dangers. The general idea is actually very simple. When doing typing completion, Leo would create a *completion namespace* by scanning the present outline for an *enclosing context*. Because the user is likely to be altering the present node, the enclosing context would probably not include that node. Modulo this complication, the auto-completer would simply look up the tree for the enclosing @<file> node, write the node to a string, and execute the string. The result would usually be *definitions* of top-level functions and classes. Voila: Leo's typing completion would have the same kinds of features that IPython has.
