Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2020-05-31: I won't be maintaining this page or responding to comments anymore (except for perhaps a few exceptional occasions). ]

---

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.

var Vector = function(x, y) {
  this.x = x || 0;
  this.y = y || 0;
};

// return the angle of the vector in radians
Vector.prototype.getDirection = function() {
	return Math.atan2(this.y, this.x);
};
