Great !

I have TexLive 2013 with texworks bundled.
I tried my lua script with the texlive texlua and it's OK, no problem with
require lpeg.
I don't know what lua interpreter Texworks uses.
How can I set it to texlua ?
But I need texworks API too : TW.xxx must work.

yes, I give you a "pb_lpeg.lua" to put in texworks/scripts directory.
(Don't forget to activate script langages in preferences). Call this script
and you have an error to load lpeg.
