JCoffeeScript

JCoffeeScript is a java library that compiles CoffeeScript 0.6.2. JCoffeeScript is licensed under the Apache license 2.0. Please see LICENSE for more detail.

Usage

from the command prompt: prompt> echo "a: 1" | java -jar jcoffeescript-0.6.2.jar (function(){ var a; a = 1; })();

from java: String javascript = new org.jcoffeescript.JCoffeeScriptCompiler().compile("a:1");

from jruby: if "java" == RUBY_PLATFORM then # use jcoffeescript implementation require 'java' class CoffeeScriptCompiler

        def initialize
            @compiler = org.jcoffeescript.JCoffeeScriptCompiler.new
        end

        def compile(source)
            @compiler.compile(source)
        end
    end
else
    # use shell out to coffee implementation
    require 'open3'
    class CoffeeScriptCompiler
        def compile(source)
            return Open3.popen3('coffee --eval --print') do |stdin, stdout, stderr|
              stdin.puts source
              stdin.close
              stdout.read
            end
        end
    end
