RedScript, a Ruby Flavored Superset Language


A Ruby Flavored JavaScript Experiment

  • Paste (almost) any JS into a RedScript file
  • Cleaner syntax for modules (AMD and CommonJS)
  • Easier class like inheritance & self based prototypal inheritance syntax

RedScript was created to provide a more native experience for modules (AMD & CommonJS), easier inheritence, and a Ruby style syntax that still behaves like JavaScript.

It was also created as a side project to learn more about Node, NPM Modules and Regular Expressions. In the future I would also like to add a proper lexer/parser to implement more advanced features like optional parens and ES5 attr_accessor like properties. Pull requests welcome ;-)

To Install Globally and Run

sudo npm install -g redscript
redscript watch [fileName fileName2]

A little RedScript...

# RequireJS AMD Modules... 
define module
require 'backbone' as Backbone                                       * see for full translation
require './views/widget' as WidgetView
# Block-like anonymous functions 
# Note, parens are currently req. around get/end, see 
app.get '/users/:name', do |res, req|                                 app.get('/users/:name', function(res,req) { 
  puts                                                  console.log(;
end                                                                   });
# Paren-free constructs 
if foo == 2                                                           if (foo === 2) { 
  puts "It's #{foo}"                                                    console.log("It's " + foo);
else                                                                  } else { 
  alert "Rut Roh"                                                       alert("Rut Roh");
end                                                                   }
# Make constructors quack like a duck 
#                                                                     # note, inheritance methods are opt. inserted 
class Duck < Animal                                                   var Duck = Animal.extend({ 
  def init(name)                                                        init: function(name) { 
    super foo, bar                                                        this._super(foo, bar);
    @name = name                                                 = name;
  end,                                                                  },
  def sayHi                                                             sayHi: function() { 
    puts 'Hello!'                                                         console.log('Hello!');
  end                                                                   }
end                                                                   });
