LALR parser to LPG & error recovery [message #570179]

Hi,

I have a working LALR parser, can I easily transform it into an LPG
grammar?

LPG doesn't seem to have associativities and precedence keywords. What
kind of parser technology does LPG use?

I am particularly interested in error recovery, so that an AST can always
be built for programs that are being edited in Eclipse. I have read that
LPG has a good error recovery mechanism. How do I use it?
