Cool, thanks! I was on the right path, just missing the classmatch() call.
Here's what I've come up with that works but *usually* gives regex errors,
though not always, and the junk in quotes changes, making me think there's some
sort of memory boundary issue. Am I doing something wrong or should I open a
support ticket?
bundle common def {
vars:
"global_pilot_hosts" slist => { "gdcscf3lgmt01", "foo", "bar-a",
"baz-b", "blah" };
classes:
"pilot_hosts" or => { classmatch(canonify("$(global_pilot_hosts)")) };
}
bundle agent blah {
vars:
"pilot_host_list" slist => { @(def.global_pilot_hosts) };
classes:
"gold" and => { regcmp("gd.*", "$(sys.uqhost)") };
reports:
gold::
"$(pilot_host_list)";
}
# /var/cfengine/bin/cf-agent -Kf ./pilot_test.cf
Regular expression error "missing )" in expression "(€¬ ଠ" at 9
Regular expression error "missing )" in expression "(€¬ ଠ" at 9
Regular expression error "missing )" in expression "(€¬ ଠ" at 9
[...snipped 80 more of those errors...]
R: gdcscf3lgmt01
R: foo
R: bar-a
R: baz-b
R: blah
#
Another error message I've seen in otherwise identical output is:
Regular expression error "missing terminating ] for character class" in
expression " E[ XE[ " at 9
Thanks,
Justin

Subject: Re: Turning a hostname list into a class list
Could we do something like this following?
classes:
"test_hosts_c" or => { classmatch(canonify("$(test_hosts)")) };
Cheers,
