The light ES6 syntax. With many of the great features from CoffeeScript landing in ES6, but a very conservative path for ES6 feature to come to coffeescript (and many ES5 features still not in coffeescript coughnamed functionscough), AmericanoScript will bridge the gap as merely a reduction of some "clutter" in the language.

AmericanoScript Syntax is an ES6 shorthand, with these features:

• Indent/Dedent to control blocks (Python, Coffeescript)
• CS Aliases (and, or, is)
• No Semicolons (Insert a semicolon at end of every non-ambiguous line)
• Heredocs """, #{} for interpolation.
• Block Regex /// ... /// with whitespace.
• Drop parens around control structures (if, for, while, switch)
• Existential Operator (foo.bar?.baz?)
• Array slice/splice (foo.bar[i..j], foo.bar[m...n] = [])
• Drop parens around callbacks.
• Literate (markdown document, with parsed code blocks.)(Might get dropped.)

Targets - while not targeting these languages specifically, using the features should "Just Work".

• AtScript

  @Component()
  class MyApp
    server:Server
    @Bind('name') name:string
    @Event('foo') fooFn:Function
  
    @Inject()
    constructor(@parent server:Server) {}
    greet():string {}

  Compiles to

  @Component()
  class MyApp {
    server:Server;
    @Bind('name') name:string;
    @Event('foo') fooFn:Function;
  
    @Inject()
    constructor(@parent server:Server) {}
    greet():string {}
  }

• TypeScript

  class Greeter
      constructor(public greeting: string) { }
      greet()
          return "<h1>" + this.greeting + "</h1>"
  
  var greeter = new Greeter("Hello, world!")
  var str = greeter.greet()
  document.body.innerHTML = str

  Compiles to

  class Greeter {
      constructor(public greeting: string) { }
      greet() {
          return "<h1>" + this.greeting + "</h1>";
      }
  }
  var greeter = new Greeter("Hello, world!")
  var str = greeter.greet()
  document.body.innerHTML = str;

• ES5

  var Path = require('path')
  module.exports = function bootstrapConfig(config)
      config.vendors = config.vendors or {}
      config.vendors.prefix = config.vendors.prefix or []
      config.vendors.prefix.push(Path.resolve(__dirname, '../node_modules'))
  
      config.vendors.js = (config.vendors.js or []).concat([

          'bootstrap/dist/css/bootstrap.css',
          'bootstrap/dist/css/bootstrap-theme.css',
      ])
      return config

  compiles to

  var Path = require('path')
  module.exports = function bootstrapConfig(config) {
      config.vendors = config.vendors || {}
      config.vendors.prefix = config.vendors.prefix || []
      config.vendors.prefix.push(Path.resolve(__dirname, '../node_modules'))
