How to apply metadata to all files in a content directory

Question

I have a content directory called foo and I want all files under that directory to have an extra metadata item foovar: default, unless explicitly overridden in the file header. I think I'm supposed to do this with EXTRA_PATH_METADATA, but I can't figure out what incantation it wants.

(for my current use case I'm trying to apply template: sometemplate within this dir, but I'm interested in solving the general case as it would make several related headaches go away)

Answer 1

This wasn't possible at the time I asked. I've since sent the devs a PR adding support, and it's been merged to master. Presumably it will go out in the next release. It makes EXTRA_PATH_METADATA recursive, so you can apply settings to a subdir like this:

EXTRA_PATH_METADATA = {'dirname/subdir': {'status': 'hidden'}}
