redscript v0.0.4

RedScript

A Ruby flavored superset of JavaScript

• Paste in compatibility with JS (except a few keywords)
• Cleaner syntax for AMD modules (or opt out)
• Easier prototypal inheritance
• Cleaner ES5 object literals
• Optional Ruby/CoffeeScript like aliases
• String interpolation
• Arrow function -> and (foo, bar) ->
• ------ Check History.md for current working syntax ------

RedScript was created to provide a better syntax for AMD modules and to provide a few aliases to make things a bit nicer to work with (my favs being func, @, puts, ->, and >>).

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 propper lexer/parser to implement more advanced features like optional parens and optional var declarations (feel free to fork!).

You can read more about it on my blog: Introducing RedScript.

To Install and Run

npm install -g redscript

redscript fileName1.rs fileName2.rs
redscript watch fileName1.rs fileName2.rs

Learning RedScript is easy, add a bit here and there until you're comfortable!

# No RedScript syntax, still works!
function sayHello(name) {
  console.log("Hello " + name);  
}

# A little bit of RedScript, func is a more terse alias function, string interpolation
func sayHello(name) {
  console.log("Hello #{name}");
}


 # A lot of RedScript, alias brackets with do/end, puts aliases console.log
func sayHello(name) do
  puts "Hello #{name}"
end

A better AMD RequireJS syntax

define module                                                   define(
require 'jquery' as $                                           ['jquery',
require './views/widget'  as Widget                             './views/widget'], function($, Widget) {        

var options = {                                                    var options = {

end                                                                 }           
                                                                }); 

define module
require "jquery" as $

# Arrow function, great for parameters, (opt parens not currently avail.)
myBtn.on 'click', ->
  $('.widget').slideToggle "slow"
end

# Alias @ with this.
model.on('change', @render)


# Private blocks
foo = 200
private
  foo = 10
end
alert(foo)  # alerts 200


# Paren free if/for/while
while foo is 200 do
  puts "I'm looping forever"
end
