jex v0.1.7

jex

Jex is a compiler that compiles scheme like language to javascript code.

usage example (in coffee script)

Jex = require 'jex'

console.log Jex.compile """
  (block
    (def f (func (x) (if (gt x 1000) "big number" "small number")))
    (f 50)
  )
"""

Jex.compile will return an object that contains the compiled code as string and array of variables the code uses, but not defines itself.

{ 
  code: '((f = (function(x) { return (gt(x, 1000))?("big number"):("small number"); })), f(50))',
  refs: [ 'gt' ] 
}

If you want a callable javascript function instead of a code text, call Jex.compileToFunction. It will return a javascript function object extended with field argNames which contains the refs (see Jex.compile above).
