TypeScript Signals released

[rich]

Signals are a light-weight, strongly typed messaging tool and we use them extensively in our game framework. And we’ve just released our TypeScript implementation for others to benefit from. It’s a conversion of js-signals by Miller Medeiros, which is of course in turn a conversion of AS3-Signals by Robert Penner.

 

You can get TypeScript-Signals from github.

If you are unfamiliar with Signals, how they work and how they compare to Events then this short summary is well worth a quick read, but to summarise:

 

• A Signal is essentially a mini-dispatcher specific to one event, with its own array of listeners.
• A Signal gives an event a concrete membership in a class.
• Listeners subscribe to real objects, not to string-based channels.
• Event string constants are no longer needed.
• Signals are inspired by C# events and signals/slots in Qt.

 

I ported over all of the 18 unit tests to TypeScript as well. So you have plenty of examples: from adding a basic listener up to manual binding and dynamic context switching.

That;s quite nice.

 

It's something i needed yesterday and this is what i found yesterday:

Your version is a bit better version, some more types, no module, and maybe more up to date with typescript since other is 5 months, so I'm switching to yours.

 

 

a little offtopic:

I'm halfway trought converting the Ash entity framework from as3, and your conversion tools is really nice starting point.

One thing I'm adding now is a Vector class in TypeScript which is something.

Overall I'm quite enthusiastic of TypeScript future, and future codebase.
