Issue #11331 has been updated by Steve Shipway.
Many thanks for your work on this feature, which will help us no end -- once we fix our current modules to be v3.x compatible and we upgrade to v3 on our puppet server, of course. The new syntax looks convenient and understandable, and more Ruby-ish (I'm from a Perl background so my initial example was perl-ish) ---------------------------------------- Feature #11331: Add 'foreach' structure in manifests https://projects.puppetlabs.com/issues/11331#change-81513 Author: Steve Shipway Status: Needs Decision Priority: High Assignee: J.D. Welch Category: language Target version: 3.x Affected Puppet version: Keywords: ux backlog Branch: https://github.com/puppetlabs/puppet/pull/1420 I doubt this would be simple to do, but it would be very useful to be able to do something like this: $variable = [ 'a', 'b', 'c' ] foreach $loop $variable { file { "/tmp/$loop": content=>"I am file $loop"; } } While it is already possible to use an array as a namevar to get something similar, it doesnt allow you to have calculated parameters as well. This would not be expected to break the declarative nature of puppet, though it would bring in a new variable scope in the loop. Using a define with an array for the namevar would work provided the top level could not be called multiple times. We want to have something like this: define firewall($users,$port) { iptables::open { $users: port=>$port; } } node foo { $webusers = [ 'fred', 'sid' ] $sshusers = [ 'fred', 'joe' ] firewall { port80: users=>$webusers, port=>80; } firewall { port22: users=>$sshusers, port=>22; } } This example would fail because the iptables::open define is called with user 'fred' two times (although with a different port parameter). If we could instead have a foreach iteration then something like this would be useable: define firewall($users,$port) { foreach $users { iptables::open { "$loop:$port": user=>$loop, port=>$port; } } } This would ensure a unique namevar for iptables::open. We would also be able to do things like initialise an array of users with different metadata parameters (eg, their full names pulled form LDAP) -- You have received this notification because you have either subscribed to it, or are involved in it.
