[antlr-interest] Free / Open JSON Grammar?

[Randall R Schulz]

Hi,

I was sure this would be settled with a quick Google search, but instead 
I've come up dry.

Does anyone know of or have to offer an ANTLR grammar (preferably for 
ANTLR v3) for JSON?

Alternatively, a JavaScript / ECMAScript grammar from which I could 
extract the literal data decoding productions would suffice.


Thanks.
