Using xText content assist from an proprietary plugin [message #722121]

Hello all,
I'm currently developing a plugin which will provide content assist to various proprietary configuration files.
As some of those files contain DSLs (with their own grammar), I was wondering whether or not it is possible to define their grammar in xText and then use xText as a "black box" of sorts to create content assist proposals from within my own plugin (i.e. not using xText's editor for the defined DSL grammar but using xText via an API of sorts).

Anyone know if this is possible?
Would really appreciate any points in the right direction.
Thanks,
Roded

Hi Roded,

I think you have to dig into the implementation of the template-proposal
language which does something similar. Please note that it was not meant
to be reused and is only poorly documented but it pretty much does the same.
The respective proposal provider can be found here:
http://git.eclipse.org/c/tmf/org.eclipse.xtext.git/tree/plugins/org.eclipse.xtext.ui.codetemplates.ui/src/org/eclipse/xtext/ui/codetemplates/ui/contentassist/CodetemplatesProposalProvider.java#n302

where complete_Literal is the interesting part, especially
temporaryResourceProvider.useTemporaryResource(..) is the call that
produces a dynamic resource with a model that is computed from a
blackbox-literal.

Please don't hesitate to ask if you have any questions.

Regards,
Sebastian

Hey Sebastian,
I'd have to do some (a lot) more digging before I'll have any more intelligent questions on the matter.
Many thanks for the reply.
Hopefully, you'll hear from me again.
Roded
