I think that I understand your intent - probably you're working on Jinja-templated Ansible manifests and want to have at least some sort of highlighting, but I don't think that we can accept this solution upstream.

The proper one would be composite syntaxes for multiple languages, which our engine doesn't support.

Your kludge of just ignoring Jinja constructs and highlighting YAML anyways might (or might not) be better than nothing, but this brings another question: where do we stop?

Do we add j2 extension to every file that can be templated? This is obviously nonsense. And for now we have no precedent for doing this.

I'm afraid that at the moment, the best place for such changes if you really want them is per-user customization.

Thanks, noted. Regarding "where do we stop" one approach could be pragmatic - whatever is popular enough :)
But I can understand the desire to keep it max clean.
Is there any way to override or add one line only, and read the rest from the system-wide file?

Oh, it's more like cleanish, or at least not much dirtier than it currently is... :-/

I think you might be able to include the global syntax from the local one, but I haven't checked. This could be a solution for #1984.
