access to AST of pegjs

[ek.s...@gmail.com]

Hi,
I wanted to specify a grammar, call pegjs.buildParser and then access the AST corresponding to the grammer to, say create programs following the grammar.

Do you think pegjs allows me to do that?

thanks

PEG.js exports its grammar parser in the "parser" property. Just do:

var ast = PEG.parser.parse(input);

and you'll have the AST in hand.
