v0.12.0

Updates from 0.11.0.

• Updated
  • Supported a numbered parameter of a function argument.
    • It is available from _1 to _9, and _1 is the first argument.
    • _ is also available and it is assigned the variable according to the order of appearance.
      • (&() => _ + _) is same as (&() => _1 + _2)
  • Supported a callback block syntax when a callback function is the last argument parameter.
    • For example, f(2, 10) { &(a, b) return a + b; } means f(2, 10, &(a, b) => { return a + b; }).
    • For another example, you can pass a block to .map like [4, 5, 6].map { => _1 * 2 }.
    • See this example to check the supported syntax.
  • Supported the syntax to skip a parameter to ignore assignment like [a,,c] = [1,2,3].
  • Supported the syntax of array assignement with a function argument.
    • A function argument example is function func([a, b]) { /* ... */ }.
  • Supported the syntax to get the value of an object property like var {xxx} = { xxx: 100 }.
    • In this case it assigns 100 to the variable of xxx which is same name as a property name.
    • This syntax can be used only as a declaration or a function argument.
    • A function argument example is function func({ xxx, yyy }) { /* ... */ }.
  • Improved .each for Object. The callback will receive [key, value] pair as array.

    { x: 100, y: 200, z: 300 }.each { &([key, value])
        System.println([key, value]);
    };
    

  • Some bug fixes and improvement.
