Topic: Instances of a given class
Sébastien Gouëzel (Sep 14 2025 at 12:56):
Is there a simple way to get the list of all registered instances for a given class? (not on master, where doc-gen does this). I'm using the class_abbrev mechanism to try to unbundle norm stuff from algebra, and I need this to check I didn't mess up (or fix the mess :-)

you can try #synthing it
Aaron Liu (Sep 14 2025 at 12:57):
and look at the trace

Don't we have #instances?
Aaron Liu (Sep 14 2025 at 13:03):
oh we do, it's in Batteries.Tactic.Instances
Aaron Liu (Sep 14 2025 at 13:04):
that's probably a better way
Sébastien Gouëzel (Sep 14 2025 at 14:19):
#instances is perfect, thanks! (But thanks also for the #synth suggestion :-)
