cljs

An experimental Clojure(ish) to Javascript compiler.

Docs: http://zk.github.com/cljs

Usage

1. lein new cljs-test

2. Add a :cljs entry to your project.clj:

   (defproject... :cljs {:source-path "src/cljs" :source-output-path "resources/public/js" :source-libs [some-ns.app] :test-path "test/cljs" :test-output-path "resources/testjs" :test-libs [app-test]})

3. Verify the above paths exist.

4. Add [cljs "0.3.0"] and [lein-cljs "0.2.1"] to your :dev-dependencies.

5. Then lein deps and lein cljs watch. This will start the watcher, which will automatically recompile your cljs libs when cljs source files change.

6. You now have the ability to use lisp full-stack (kind of), begin global domination.

Examples

See http://github.com/zkim/cljs-contrib, specifically:

• project.clj for info on the :cljs opts map.

• Clone the repo and open resources/border-layout.html and resources/panel.html in your browser. This will give you an idea of how to use the compiled cljs output.

Be sure to include underscore.js in a script tag before including any compiled cljs output.

Todo

• Integrate Google's Closure Compiler for minifying
• Integrate js-test-driver for testing

Missing Features

• REPL -- Browser stuff from https://github.com/ivan4th/swank-js & comm from swank-clojure

• Macros

• TCO -- Possible with CPS? http://eriwen.com/javascript/cps-tail-call-elimination/
