jcoffeescript's Introduction

JCoffeeScript

JCoffeeScript is a java library that compiles CoffeeScript 1.1.

Usage

from the command prompt:

echo "a = 1" | java -jar jcoffeescript-1.1.jar

      (function() {
          var a;
          a = 1;
       })();

####Command Line (unix/windows):

java -jar jcoffeescript-1.1.jar < foo.coffee > foo.js

####command line options:

--bare - compile the javascript without top-level function safety wrapper.

####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
end
compiler = CoffeeScriptCompiler.new
compiler.compile('a = 1')
