properly create gap_functions.py

[Dmitrii Pasechnik]

Currently gap_functions.py lists some subset of all available in GAP things - and the rest are not available. I often find myself adding stuff there...

Is it possible instead to create gap_functions.py on the fly (just once), in the same way as tab completions are created for maxima library interface? Then nothing will be missed.

This is really a Sage question, as that file is only in Sage.

There are lots of undocumented GAP functions that we IMHO shouldn't make available in the tab completion. I don't know how to get the list of "blessed" functions automatically. You can always define missing functions interactively using something like

sage: FreeGroup = libgap.function_factory('FreeGroup')

But if you have anything that should be in gap_functions.py then definitely put it in there.

In GAP dev-tree there are scripts to generate the index file for the GAP documentation. I imagine the index items are more or less the things we want to put into gap_functions.py
