New issue 2589 by asmeurer: Implement tab completion in SymPy Live
http://code.google.com/p/sympy/issues/detail?id=2589
We should make TAB do tab completion at live.sympy.org.
This is actually pretty straight-forward. You just have to use the
rlcompleter module (part of the Python 2.5 standard library and included in
the App Engine).
The usage is something like
completer = rlcompleter.Completer(globals()) # Or locals(), I'm not sure
completer.global_matches("x")
[xrange, x, xthreaded]
completer.attr_matches("x.is_fi")
[x.is_finite, x.is_finite, x.is_finite, x.is_finite, x.is_finite,
x.is_finite, x.is_finite, x.is_finite, x.is_finite]
I don't know why the last one gives duplicate results, but it's easy enough
to remove them (list(sorted(set(completions)))).
And I checked: if you add "case SymPy.Keys.TAB:" to sympy-core.js, it works
(at least in Safari).
Actually, if I knew Javascript, I would implement this myself.
