We have an extension for Visual Studio Code and we want to build custom content assist proposal provider.

We want to be able to generate a random UUID, when the user defines a UUID property, this UUID property is part of our grammar.

Person:
       'person' name=ID '{' 
                 'uuid'=UuidValue
       '}'

for Eclipse plugins Xtext automatically generates a [Language]ProposalProvider, and all one needs to do is to overwrite a method which is named like this: complete_UuidValue

However, for generic IDE, the solution of XText seems to be very complex. All we get is a IdeContentProposalProvider , which doesnt seem to offer many good opportunities to play with or extend.

Is there any good, reliable way to achieve this, without breaking something? Thanks

sorry. you have to deal with IdeContentProposalProvider and if else there:

org.eclipse.xtext.ide.editor.contentassist.IdeContentProposalProvider._createProposals(RuleCall, ContentAssistContext, IIdeContentProposalAcceptor)

see StatemachineWebContentProposalProvider in xtext-web (at github)
