I’ve not following the details here, but if this is only about suppressing expected warnings in the doc builds, a warnings filter in conf.py would be the way to go.

Not sure how since we want one warning per missing font to print out at once. I tried using the once filter and couldn't get that working.

Ah sorry, I was thining about warnings.warn() not logging.warning(). Forget the filter comment then.

I would base deduplication on the message. Separate ids is more effort than it's worth. Likely the simplest approach is to wrap your logging in use a functools.cache.

Going down that rabbit hole, it looks like the least extra/most generalizable may be to make a custom loghandler or use a handler filter (which is what I'm trying now)

So uh adding a filter works really nicely, and I can move it to the sphinxextensions - there's one for missing references I used as a model-but I think the multiple prints are annoying in any context. Only problem is it works a bit too well and I can't get the messages to show up on new runs -> any tips for resetting the msg_cache on new runs?
