[erlang-questions] Question about gproc and "wildcards"

[Gregory Haskins]

Greetings Ulf, all,

Question about gproc.  I am using gproc in a variety of ways, one of
which is as a pub/sub mechanism as advertised in the readme.md (see:
https://github.com/ghaskins/edist/blob/master/lib/src/main/erlang/edist_event_bus.erl
as an example).

What I am wondering is, is there a way to "subscribe" to something with
wildcards?

For instance, can I say "subscribe({interesting_event, '_'})" such that
I would get notifications for

notify({interesting_event, foo})

as well as

notify({interesting_event, bar})

I am a bit unclear if or how this could be done.

Thanks!
-Greg
