Re: Low memory lua parsing

[Robert Virding <robert.virding@...>]

You can take the Lua grammar definition at the end of the manual and put it into an LALR(1) parser generator like yacc and get it to generate a parser which just checks the syntax. It is almost LALR(1) and needs ony one small modification and a check function for it work. This is what I have done for Luerl.
