[Caml-list] JavaScript interpreter in OCaml

[Diego Olivier Fernandez Pons]

    Caml-list,

Does anyone have a JavaScript interpreter in OCaml ? Doesn't need to
be 100% compliant, the user can always rewritte some parts of the
JavaScript. And we discourage using weird / complex JavaScript
constructions anyway. Alternatively, a JavaScript -> OCaml source to
source translator could be good as well.

I searched for it one day and didn't found anything.
But there's Pffff which contains a JavasScript parser and a beginning of
AST analyser :

I don't know whether you mean written in pure OCaml or just usable from OCaml. For the latter, I've used Alain Frisch's SpiderCaml: http://alain.frisch.fr/soft.html#spider

Personally, I'd say that linking to a well-maintained interpreter is a better solution than yet another implementation of JavaScript with all the warts that go with doing that.

HTH,


David

I've never tried it, but there is:

We'd love to have people play with this, but beware it's an interpreter
extracted from a Coq development (correctness trumps efficiency), and
many parts of the language are still missing. We're working on extending
it, but I don't think it's ready for prime time yet.

Best,

Alan
