Stack Traces for Backbone.Events triggers

========================================

A quick little snippet of Javascript to debug Backbone.Event.trigger stack

traces. On trigger loops, it provides a much easier to read stack trace of

calls to `trigger` as opposed to every line of JavaScript.

## Usage

Just use backbone events as normal. When you see a loop, things will be better.

    item.trigger_infinite = function() {

      this.trigger 'infinite'

    }

    item.on('infinite', function() {

      this.trigger_infinite()

    })

    item.trigger('infinite')

Instead of a browser using 100% of your processor, you'll see this in your

console:

    .... snip ....

    [object Object].trigger_infinite (file://localhost/<...>/spec/spec/Backbone.StackTraceSpec.js:40:21) 126

    [object Object].trigger_infinite (file://localhost/<...>/spec/spec/Backbone.StackTraceSpec.js:40:21) 127

    Backbone.StackTrace: stack too deep (128) 

You can set the max stack depth like so:

    window.Backbone.StackTrace.maxDepth = 256;

If you want to see the stack trace working for everything, not just loops, do this:

    window.Backbone.StackTrace.verbose = true;

#### Known Issues

I'm not sure how to fake a thread-local variable in JavaScript, so things

working asynchronously will clobber each other.

## Installation 

To use the stack tracer, include it after backbone. It has a single dependency,

a stack tracer, available from

. A copy of the stack tracer

is also available in the spec directory if you're lazy.

It's not recommended for production use. Shoot, I'm too lazy to even minify

this stuff.

    

    

    

That's it, you're done.

#### Paperwork

This is unencumbered code entered into the public domain, suitable for

copy-pasting into some other project of your own. See the attached UNLICENSE

file for more information.

Open spec/SpecRunner.html to run the tests, such as they are.
