I'm curious about what you need that's different from what
ClojureScript provides: a mechanism for compiling a subset of Clojure
to JavaScript code that behaves like you'd expect the Clojure code to
behave.
One common category of need that ClojureScript doesn't currently
fulfill is translating Clojure native collections (vectors and maps)
to JavaScript native collections (arrays and Objects). Instead,
Clojure native collections are translated into immutable,
structural-sharing collections implemented in JavaScript. ...but I
don't think that's what you're describing as a need here.
user=> (require '[clojure.contrib.clojurescript :as cljs])
nil
user=> (println (cljs/formtojs '(defn foo [x y] (+ x y))))
(function __user_fn_528(){
return (clojure.JS.def(user,"foo",(function __user_fn_528_foo_530(x_1,y_2){
return (clojure.lang.Numbers.add(x_1,y_2))})))}).apply(null,[])
nil
ClojureScript is not yet up to date with the recent lazy-seq changes.
