## jilorg_fix_filenames.py
#!/usr/bin/env python
"""
Fixes file names for downloads from jil.org.

jil.org delivers downloaded files with file names in e-mail header format. The
fix_filename function from this module can decode such file names.

When this module is executed as main program, all file names passed as program
arguments are renamed properly:

## hastouch.html
<!doctype html>
<title>has touch?</title>
<h1>Has this device touch? </h1>
<script>
var isTouch = (function(){
  try{
      var event = document.createEvent("TouchEvent"); // Should throw an error if not supported
      return !!event.initTouchEvent; // Check for existance of initialization method
  }catch(error){
      return false;

## Usage
var a = new Angle().radians(Math.PI * 3 / 4),
    b = new Angle().degrees(135);

var c = new Angle(a + b);

Math.sin(a);
Math.cos(b);

a.add(new Angle().degrees(30));
b.add(Math.PI);

## point.js
function Point(x, y) {
  if (arguments.length === 1 && typeof x === 'string') {
    return x.slice(1, -1)
      .split('}{')
      .map(function(tuple) {
        return tuple.split(',', 2).map(parseFloat)
      })
      .reduce(function(point, coords) {
        point.x += coords[0];
        point.y += coords[1];

## point.js
/*
  A point constructor that creates objects supporting addition and subtraction.

  The "trick" is to use 32bit integers and stuff two fixed 16bit fixed point
  numbers into them that represent the coordinates of the point.

  This approach has problems with overflow. E.g. when adding two points (0, 2)
  and (0, -2), the addition will cause the y values to overflow into the 17th
  bit, which is part of the x-value. When subtracting two points, e.g.
    (.00390625, 0) - (0, -128)

## naive-super.js
Object.defineProperty(Object.prototype, 'super', {
  get: function() { return Object.getPrototypeOf(this); }
});

function Foo() {}
Foo.prototype.reset = function() {
  this.fooProp = 'reset';
  console.log('Foo#reset()');
}

## super-proxy.js
Object.defineProperty(Object.prototype, 'super', {

    var context = this;
