Modify template proposal description [message #1802618]

Is there a way to modify template proposal description?

I made a templates.xml file and I can use templates which were defined in that file, but I also need to change proposal's description (a text in a little yellow window which appears beside a window with proposals).

Xtext ususally binds
org.eclipse.xtext.ui.editor.templates.DefaultTemplateProposalProvider

org.eclipse.xtext.ui.editor.templates.AbstractTemplateProposalProvider.doCreateProposal(Template, TemplateContext, ContentAssistContext, Image, int)
create a XtextTemplateProposal

which is a org.eclipse.jface.text.templates.TemplateProposal which offers org.eclipse.jface.text.templates.TemplateProposal.getAdditionalProposalInfo() and thus implements org.eclipse.jface.text.contentassist.ICompletionProposal.getAdditionalProposalInfo()
and is implemented by XtextTemplateProposal

=> speciizing DefaultTemplateProposalProvider,
creating a sublclass of XtextTemplateProposal with getAdditionalProposalInfo
+ override to bind org.eclipse.xtext.ui.DefaultUiModule.bindITemplateProposalProvider()
should do the trick

For an example see https://github.com/eclipse/gef/blob/master/org.eclipse.gef.dot.ui/src/org/eclipse/gef/dot/internal/ui/language/contentassist/DotTemplateProposalProvider.java

Thank you both!

I created a new class inside mydsl.ui.contentassist package which extends DefaultTemplateProposalProvider and which was binded inside UiModule class.

I also created a new class which extends XtextTemplateProposal but I don't know where to instantiate that class.
