Issue #16286 has been updated by J.D. Welch. Keywords changed from undef dsl to undef dsl backlog
---------------------------------------- Feature #16286: add || operator https://projects.puppetlabs.com/issues/16286#change-74206 Author: Andrew McNaughton Status: Needs Decision Priority: Normal Assignee: J.D. Welch Category: Target version: Affected Puppet version: Keywords: undef dsl backlog Branch: There's a pattern in common usage that goes like this: class foo ( $val = undef ) { $real_val = $val ? { undef => $name, default => $val, } resource bar {baz: val => $realval} } It's an ugly hack. It would be a lot simpler like so: class foo ( $val = undef ) { $real_val = $val || $name resource bar {baz: val => $realval} } Or, (where templates are not involved): class foo ( $val = undef ) { resource bar {baz: val => $val || $name} } The && and ||= operators common in other languages might also be useful at times, and their meanings from other languages are well known and unambiguous. However, || is the one I'm feeling the strongest need for. The common need for $real_val as above grates a bit too. I imagine it would be a more complex change to implement, but what if the values passed as parameters could be overridden once in the same way as ones from an inherited class? Presumably the externally provided parameters would get their own namespace. -- You have received this notification because you have either subscribed to it, or are involved in it.
