Nesting rules in hobbit-alerts.cfg

Is it possible to nest rules in hobbit-alerts.cfg?  For example, can I do
something like this (indenting provided for readability):

PAGE=hostPageA NOTICE RECOVERED
     HOST=hostA,hostB,hostC
          MAIL user-662c32254ab8@xymon.invalid
     HOST=%(hostD[0-9])
          MAIL user-2a94730ebdd3@xymon.invalid

Our alerting rules are starting to get kind of complex, and nesting alert
rules as above would make things easier.  I know I could do something like:

PAGE=hostPageA NOTICE RECOVERED
     MAIL user-662c32254ab8@xymon.invalid HOST=hostA,hostB,hostC
     MAIL user-2a94730ebdd3@xymon.invalid HOST=%(hostD[0-9])

But some of the HOST= lists are very long (i.e. wrap across multiple lines),
so the above 2nd example would look a lot uglier than it does in this post
(which was simplified for readability).  If nesting rules won't work, I
wonder how much effort would be involved in adding this feature.

Did you look into maybe making a host group out of them?

I forget the hobbit term for them of course, but I know you can do
groups, which is a regex or simple declaration.

That was one thought I had, but the current version of Hobbit doesn't
display the group alerting under the "info" column.  But I do currently have
some group alerts set up.  I'm just looking at ways to clean up and simplify
the alert rules.

You could use macros...

$hg-pager=%(^hostA|$hostB|^hostC)
$hg-email=%%(hostD[0-9])

PAGE=hostPageA NOTICE RECOVERED
     HOST=$hg-pager
          MAIL user-662c32254ab8@xymon.invalid
     HOST=$hg-email
          MAIL user-2a94730ebdd3@xymon.invalid

This keeps all the clutter out of the rule sets.

Gary,
 
One way to clean up and simplify your alert rules is to use a (host group)
macro, as in http://www.hswn.dk/hobbiton/2005/01/msg00287.html (but see also
http://www.hswn.dk/hobbiton/2005/01/msg00123.html for a tighter syntax) so
long as these macros can run across lines...
