Can xtext propose styled string in template proposals?

Question

Can xtext propose styled string in template proposals? Normal createCompletionProposal could have that but I didn't find any API returning StryledString in ITemplateProposalProvider hierarchy.

Answer 1

You would have to extend TemplateProposal and add ICompletionProposalExtension6 in order to deal with styled strings in the display string of the template. That's not a class from Xtext but from the underlying Eclipse content proposal framework.
