Embedding a language in Java comments/annotations [message #778391]

Hi,

I admit I haven't done much research on XText, but I figured I'd ask a simple question here first, just to see if my problem is solvable with XText.

I want to embed my own language inside certain Java annotations. Currently, I pass small programs written in my domain specific language to those annotations as plain strings, so that everything is just plain old Java. Now what I want to do is, I want to keep everything as is (i.e. everything is still plain Java), but I would like to get all the goodies for my language inside those special strings (custom syntax highlighting, type checking, code completion, etc.). Is it possible use XText to alter the Eclipse editor for ".java" files?

Thanks.

Hi Aleksandar,

this is not possible with Xtext and I'm not sure whether the JDT
provides the necessary abstractions to accomplish this. You may want to
ask in the JDT newsgroup for custom highlighting and content assist for
strings in annotations. ObjectTeams may help to hook into some internal
stuff of the JDT, too.

Regards,
Sebastian

But what he maybe could do is to have a Xtext editor pop up on a special key combination from the JDT editor containing and conveniently editing the comment that he is currently at?

Yes, that is certainly possible. It wouldn't help with the coloring for
nicer reading of existing code, though.
