Issue #2491 has been updated by Thomas Bellman. File 0001-Make-regsubst-function-operate-on-arrays-feature.patch added Status changed from Needs design decision to Ready for Checkin
The attached patch has been posted to puppet-dev, and Luke has given it +1. ---------------------------------------- Feature #2491: The regsubst() function should be able to operate on arrays http://projects.reductivelabs.com/issues/2491 Author: Thomas Bellman Status: Ready for Checkin Priority: Normal Assigned to: Thomas Bellman Category: functions Target version: 0.26.0 Complexity: Easy Affected version: 0.25.0rc1 Keywords: It would be nice if one could give an array to regsubst(), and make it perform the substitution on each element of that array. One, perhaps non-obvious, use case is to have a definition that takes an array as parameter, and have it "loop" over that by giving it as the name parameter to a helper definition, like this: <pre> define my_define($param, ...) { $x = regsubst($param, ".*", "$name//\\&") my_define_helper { $x: ...; } ... } define my_define_helper(...) { $n = regsubst($name, '^(.*)//(.*)$', '\1') $p = regsubst($name, '^(.*)//(.*)$', '\2') # Do things with $n and $p, which now are the $name and one # element of $param from my_define, respectively. } my_define { "foo": param => ["a", "b", "c"], ...; "bar": param => ["a", "b", "c"], ...; } </pre> One can already do the looping today, but only as long as the param parameters to My_define[foo] and My_define[bar] doesn't have any elements in common. (This use case came up in puppet-users recently, where the poster wanted a definition for managing PGP keystores, where one parameter would be an array of keys. http://groups.google.com/group/puppet-users/browse_thread/thread/d3e85f7869f66ed1) -- You have received this notification because you have either subscribed to it, or are involved in it.
