Collapsing all comments [message #1065505]

Hi,

I would like to collapse by default all multi-line comments in my xtext editors.

I've looked around and found out that this may be done through the ProjectAnnotationModel but :

1) how do I retrieve the ProjectAnnotationModel, I always get null when using the following instruction:
ProjectionAnnotationModel model = (ProjectionAnnotationModel) xtextEditor.getAdapter(ProjectionAnnotationModel.class);

2) where do I insert the code, i.e. which hook should I use ?

thanks in advance for any hints, pointers on how to achieve this.

Hi,

for folding customization you may have a look at this post and the two corresponding projects on github
Terminology and Xturtle.

The overridden XtextEditor contains the code for collapsing regions on startup. Your main problem will be identifying which regions are comments and which regions are not. Currently there is no out of the box support for "typing" them. This issue is addressed in the implementation (proof of concept). For you it may much easier, simply override computeCommentFolding in DefaultFoldingRegionProvider and give the calculated regions a "comment" type.

Hi Alex,

XTurtle seems to be doing exactly what I am looking for (and even more).

thanks,
Benoît
