Jasmine Compilation

[scitesy]

The last line in the code block is the failure point. In the Jasmine library itself it is lines 62-65 that are failing. Please let me know if you need anymore information.

Code: var jasmine = {};

jasmine.getGlobal = function() { function getGlobal() { return this; } return getGlobal(); };

jasmine.bindOriginal_ = function(base, name) { var original = base[name]; if (original.apply) { return function() { return original.apply(base, arguments); }; } else { return jasmine.getGlobal()[name]; } };

jasmine.setTimeout = jasmine.bindOriginal_(jasmine.getGlobal(), 'setTimeout');

Hey, the source code looks very mangled, can you paste it somewhere it doesn't get squashed? (Github Gist, paste2.org, etc.)

So I managed to debug it, the problem is that the "setTimeout" function doesn't exist in IronJS (as it's not part of the ECMA spec) and when you do this:

var original = base[name]; if (original.apply) { }

original is undefined, since base[name] really is base["setTimeout"], which really is jasmine.getGlobal()["setTimeout"], which really just is the global setTimeout variable, which is undefined. And when you try to access .apply on undefined an exception is thrown, and this is in compliance with the ECMA3 spec, the if test should be:

if(typeof original !== "undefined" && original.apply) {

}

I know the error is a bit cryptic and doesn't give much information, I'm working on improving that :)

Thanks so much for looking into this! Sorry about the poor formatting. Next time I'll create a gist/paste bin and link it.

[fholm]

No problem! Just happy people are reporting issues so I can look into, and possibly fix them :)

Is there any plane to implement setTimeout/setInterval?

[otac0n]

@flechto, there are no plans at this time to implement any browser-specific items in IronJS. That being said, this would be an easy thing for anyone using IronJS to implement themselves.
