Re: [imp-dev] double click strategy as a service

["Robert M. Fuhrer" <rfuhrer@xxxxxxxxxxxxxx>]

Hi Jurgen,

You're right that it's not a service, but given recent changes, you can extend the class StructuredSourceViewerConfiguration, override getDoubleClickStrategy() and return any implementation of ITextDoubleClickStrategy you want.

The default implementation looks like this:

    public ITextDoubleClickStrategy getDoubleClickStrategy(ISourceViewer sourceViewer, String contentType) {

        return new DoubleClickStrategy(getLanguageServiceManager().getParseController());

    }

so you can see that it's easy to get to the IParseController, and hence to the AST.

Does this do what you need, or do you think we should really wrap this as a separate service?

I confess I'm a bit on the fence these days about wrapping everything as a service/extension point...

Hi guys,

I'd like to have the double click strategy also as a service. The
current implementation uses lexical features from
ILanguageSyntaxProperties, but what if I can use the AST to get this
information more quickly and more precisely?
Thoughts?

Cheers,

Jurgen
