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;

  • ES6

  • 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([
        'jquery/dist/jquery.js',
        'bootstrap/dist/js/bootstrap.js',
    ])

    config.vendors.css = (config.vendors.css 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'))

    config.vendors.js = (config.vendors.js || []).concat([
        'jquery/dist/jquery.js',
        'bootstrap/dist/js/bootstrap.js'
    ])

    config.vendors.css = (config.vendors.css || []).concat([
        'bootstrap/dist/css/bootstrap.css',
        'bootstrap/dist/css/bootstrap-theme.css',
    ])
    return config;
}
