See GlobbingPathFilter [1] for how globbing on paths works. Note, that
that there is no globbing on the elements of a path (yet).

Thanks Michael,
so from that list, from a Sling perspective globbing seems to be the
interesting part for me. Node types are not sufficient as we would need
to filter on resource types, and that can become really tricky due to
the type inheritance we have.
So if no one complains I'll add globbing to our new api

See my reply to Bertrand on 19.10.15 for an overview.
Regarding capabilities, Oak's filtering mechanism allows filtering by
node type, by paths (including some globbing), by access control and by
visibility (internal Oak nodes). It has additional support for filtering
events of sub trees of added/deleted/moved nodes. See implementations of
org.apache.jackrabbit.oak.plugins.observation.filter.EventFilter for
further details.
You can also implement your own EventFilter if you fancy. For most cases
though
org.apache.jackrabbit.oak.plugins.observation.filter.UniversalFilter
would do the trick. That one can be parametrised by a selector selecting
a node (relative to the current one) and a predicate to apply to that node.
Finally there is
org.apache.jackrabbit.oak.plugins.observation.filter.FilterBuilder,
which can be used to build complex filters from the basic ones.
Currently this is pretty much only used internally in Oak. But I'd be
happy to make this more publicly available if we can come up with an API.

This is probably stating the obvious, but the resource-name-filter

be compatible with oak's filter capabilities (OAK-1133)
Or a subset. It would be great, if someone can summarize those
capabilities here.
Thanks

Continuing this discussion, right now the resource listeners can
subscribe to a path and a change type (added/changed/removed).
I think a pretty common use case is to filter on the resource name, all
script implementations that cache, filter on the script extension.
Should we support this for registering the listener? And if, how?
