Possibly related: I have made Brendan Eich's Narcissus meta-interpreter into a CommonJS module, and it can be run on Narwhal. http://github.com/andychu/narcissus Since I think ES5 adds no new syntax over ES3.1, this should be an ES5 parser (?) Here is an example of the JSON parse tree generated from json-template.js (a template language in 800-ish lines of code) http://github.com/andychu/narcissus/raw/master/codegen/json-template.json Yes, it's big. So I understand why people are using more compact array-based JSON formats. There are some notes about the status in the README. The idea was to write some tools to process JavaScript code using this parser. It's rough, but working, so if anyone wants to use it let me know.
