Issue 3638 - Introduce type adblockplus::host

modules/adblockplus/manifests/host/example.pp

+# == Type: adblockplus::host::example
+#
+# An example on how to apply resource definitions that are specific to the
+# current node's $::role, but need to recognize or correspond to a subset of
+# all hosts within the same environment. One can introduce another manifest
+# corresponding to the adblockplus::host::$::role pattern when integrating
+# resources that are set up based on individual host information.
+#
+# This workaround is required due to the circumstance that module adblockplus
+# must still remain Puppet 2.7 compatible, which does not feature sophisticated
+# iteration over i.e. resource definitions or collectors, hence makes it very
+# difficult to re-use information whilst maintaining clear abstraction.
+#
+# See type adblockplus::host for more information.
+#
+define adblockplus::host::example {
+
+  # Puppetlab's stdlib allows for accessing host parameters
+  $fqdn = getparam(Adblockplus::Host[$title], 'fqdn')
+
+  # Examplary resource without side-effects
+  notify {"$fqdn#example":
+    message => "Place definitions requiring information about host $fqdn here",
+  }
+}
