[IPython-dev] eco: a composed language editor

More of a thought exercise than a discussion of actual features: i recently
read about this editor for composed languages, eco:
- site: http://soft-dev.org/src/eco/
- repo: https://bitbucket.org/softdevteam/eco/
Just from their examples, I now have this picture in my mind of a
codemirror-based, eco-like editor in a cell that lets me prototype an
interactive GUI driven by a couple SPARQL queries with python interpolated
inside the querie, without any templating stuff in sight. I can mix in
Widgets wherever I like. Hell, throw in some coffeescript and LESS.
At first glance, it's a 90's PHP nightmare, but then I remember that I can
immediately tell if all of the layers are syntactically correct, since each
layer was interactively built against a grammar, augmented by what is known
about the current running environment.
Some things I thought about:
- what is a composed kernel(s)?
- they don't really cover how one might actually *execute *one of
these files. for their example with HTML, Python, SQL, what's really
happening? in my mind, this is really just a python kernel that
and SQL as strings, but a more involved example?
- how would parser-driven editing in context work?
- the completion available in a running kernel is already far beyond
what a grammar-only completion tool can do. what would a more
parser-driven editing experience be like?
- how would one store a tree of tokens?
- presumably, storing serialized JSON in cells.source, while ugly,
would work. or metadata.
- what are visual tokens
- actually, in line with the jupyter iconography (i.e. galileo's moon),
the inlining of visual tokens would be incredible. codemirror doesn't
appear to support flowed widgets (yet?). their suggested "real" use, of a
formula editor, is interesting. And, of course, matrices.
- eco native format is gzipped JSON
- i think this has been discussed before (ipynbz). i don't know what
advantage this provides over just having the json out there, but i have
created some pretty big notebooks before. also, notebook files are not
really hand editable (though I have done so).
Interested in what other folks think...
