Sounds like a good idea to me, too. I'll see what I can do :)

At least a simple approximation of glob-syntax should be doable.

Constraints can already refer to regex now too. And we're talking about
being able to match on tags (or even attributes) on start/stop etc.

It'd make sense to then merge all this consistently, right?

(Perhaps even via a crm_resource -l option, so that pcs/crmsh use the
same matching code as the PE and as each other, if that makes any
sense.)



Regards,
Lars

I also realised that there is another complication, which is that
unless in interactive mode, the bash shell will consume the regex
syntax, and it would need to be escaped. So that would make the feature
even more confusing and doesn't seem entirely clean - although this is
a limitation of shell syntax. In theory the shell could use the
completion information to expand 'crm configure show prim*' into all
the completions for prim*.

Unifying this might be difficult, as far as I know pcs doesn't have an
interactive mode or anything similar to the configure interface of
crmsh..
