coffeescript on rhino
JCoffeeScript is a java library that compiles CoffeeScript 1.1.
from the command prompt:
echo "a = 1" | java -jar jcoffeescript-1.1.jar
(function() { var a; a = 1; })();
java -jar jcoffeescript-1.1.jar < foo.coffee > foo.js
--bare - compile the javascript without top-level function safety wrapper.
String javascript = new org.jcoffeescript.JCoffeeScriptCompiler().compile("a = 1");
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')Thanks
