There has been, but it's extremely out of date at this point: https://github.com/clojure/clojure-contrib/tree/master/clojurescript That's a pre-1.0 version of Clojure that does indeed compile to JavaScript. It supports persistent hash maps and vectors (pre-transients), lazy sequences (actually, lazy-con, pre-chunking), and most of the clojure.core functions. There's no attempt to support Clojure's concurrency constructs, and it relies on the Java-based compiler rather than having a port of the compiler itself to JavaScript. I gave up trying to hand-port all the features from the Java half of Clojure's implementation over to JavaScript, with the hope that when we eventually have clojure-in-clojure this task would be significantly easier. You can even try it out in a browser (doesn't work on Macs, I think): http://clojurescript.n01se.net/ That loads the clojure-to-javascript compiler as a Java applet, after which you can run Clojure commands in the browser, like: (-> document .body) or: (set! (-> document .body .style .background) "orange") I'm sorry it's too out of date to be of much real use now, but it does show it's possible and hopefully has some tidbits that will be useful in later implementations. --Chouser http://joyofclojure.com/ -- You received this message because you are subscribed to the Google Groups "Clojure" group.
