Folding package/ file [message #1747425]

Hello forum,
I am relatively new to DSL and am having some issues with some of the features of xtext.

I've generated a grammar which is fine and am beginning to add features such as folding and outline generation.

The outline worked fine however its the folding which is causing an issue.

Within my mwe2 file I have been able to use fragments such as "fragment = ui.outline.OutlineTreeProviderFragment2 auto-inject {}" which auto generated the outline folder in the UI project.

I have had no such luck with the folding package.

Does anyone know how to do the same so the folding package/files are auto generated?

Is there a fragment I am missing or is there another workaround available?

HI,

there is no need to have a "Fragment" for everything. you can simply add the bindings you need and create the classes you need.
fragments are just "for convenience" and there is not a fragment for EVERY extension point.

so adding a

def Class<? extends IFoldingStructureProvider> bindIFoldingStructureProvider() {
MyDslFoldingStructureProvider
}

with

class MyDslFoldingStructureProvider extends DefaultFoldingStructureProvider {

}

should do the trick
