Eclipse plugin for TypeScript?

Orion (the web based eclipse ide) would be a good fit. It is already using nodejs, so it would be easier to incorporate tsc and the language services. Right now they already support Javascript including some type inference. I understood typescript is on their radar.

Check this open source plugin which is build by palantir.

This question was asked the day TypeScript was released, so as of today (Oct 2nd 2012), there is no support. Having said that, the XText team -- a team responsible for rapidly creating DSLs -- is aware of TypeScript and I wouldn't be surprised if they do something.

Another place to look is Microsoft. Depending on what their motivation is with TypeScript, they may push for an Eclipse project (although I doubt it).
