Description

With the following manifest:

node /^ws-([[:digit:]]+)/ {
  $hostid = $2
  notice("site.pp: Hostid: $hostid")

  # Same regex as above
  if $hostname =~ /^ws-([[:digit:]]+)/ {
    notice("\$2: $2")
  }
}

When run against a machine ws-01, I get out:

puppet-master[29847]: (Scope(Node[ws-:digit:])) site.pp: Hostid: 
puppet-master[29847]: (Scope(Node[ws-:digit:])) $2: 01

Grr. horrible wiki formatting there. Try again…

node /^ws-([[:digit:]]+)/ {
  $hostid = $2
  notice("site.pp: Hostid: $hostid")

  # Same regex as above
  if $hostname =~ /^ws-([[:digit:]]+)/ {
    notice("\$2: $2")
  }
}

When run against a machine ws-01, I get out:

puppet-master[29847]: (Scope(Node[ws-:digit:])) site.pp: Hostid: 
puppet-master[29847]: (Scope(Node[ws-:digit:])) $2: 01

I’m working on a patch

patch.

Note: No tests because (as the commit makes clear) I’m uncertain whether this is the best place for the fix. I need a better understanding of the architecture of puppet.
