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;
})();
####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')
