Re: getting keywords in lua5.2

["Victor Bombi" <sonoro@...>]

This is done in the last part of my code. But this is not the point.
the point is:
On lua51 I managed to get all the keywords (global definitions of functions
and tables and the functions in this tables) from some lua files which also
used require on other lua files.

and the key functions are loadinEnv and newrequire
