FireClosure

Author(s):



(This addon has been integrated into Firebug since version 1.11.2, and is thus obsolete. There is no need to install it.)

FireClosure is an experimental Firebug extension that allows you to access closed-over ("private") variables in JavaScript, without having to mess around with tedious breakpoints.

For instance, given the following code...

function A() {
var priv = 10;
this.foo = function() { return Math.random()*priv; };
}
a = new A;

... FireClosure makes getting the value of priv as easy as a.%priv.

There is also some support for showing closures in various DOM views, hidden under the "Show Closure Variable" option of the DOM panel.

Some caveats exist, see the github README.

Feedback appreciated.
