Re: Luma errors

[Fabio Mascarenhas <mascarenhas@...>]

Hi Henk,

I wrote Luma against a pretty old version of LPEG, 0.7. I have updated
luma.re to work with LPEG 0.10, forking LPEG's re.lua. The changes are
simple:

* allow _ as a non-terminal name
* search for non-terminals in the definitions first (instead of
requiring definitions to be prepended by %)

These changes make writing and composing grammars much more convenient.

I have put a new rockspec online, and moved the repository to github:

http://github.com/mascarenhas/luma

The test suite passes with the latest versions of LPEG and Cosmo
installed (there is no luma.cosmo anymore, BTW, it just uses the
installed Cosmo).
