Hi everyone.

I have a question about the content assist.

I would like show the same things in wherever the user press CTRL+Space.
The things that I want to show are the variables defined by the user and not the keywords.
I'm looking for some method or class that I have to extend or change, but in some places the content assist isn't showed up, because for default doesn't have suggestions.
This fact is puzzling me a little bit, because when it happens none of the methods like "complete{TypeName}_{FeatureName}" or "complete_{RuleName}" are called.

In summarize...
If I'm at a new line (blank line) and I press CTRL+Space I would like to show the content assist with all variables or methods defined by the user.
But, if I press CTRL+Space in other places I would like show the same variables.
Of course, I have to treat the prefix.
The scope doesn't matter in this case. Smile

Does anyone have idea about how I can do this?

Regards,
Maicon

Hi,

the complete methods are actually called. which is called depends on the place in the grammar file.
can you elaborate a bit what you exactly want to do? you posting is way to general to give advice.
i doubt you really want to override
org.eclipse.xtext.ui.editor.contentassist.AbstractContentProposalProvider.completeKeyword(Keyword, ContentAssistContext, ICompletionProposalAcceptor)
org.eclipse.xtext.ui.editor.contentassist.AbstractContentProposalProvider.completeRuleCall(RuleCall, ContentAssistContext, ICompletionProposalAcceptor)
org.eclipse.xtext.ui.editor.contentassist.AbstractContentProposalProvider.completeAssignment(Assignment, ContentAssistContext, ICompletionProposalAcceptor)
in general
