We've Moved!

Ticket tracking is now hosted in JIRA:


See the below script. In my opinion the right order of evaluation here would be: 1) A direct lookup – in this case, the key ‘false’ 2) Any regular expressions – order is up in the air; declaration order perhaps? 3) default – if all else fails, that should be the right answer.

Note, that in my opinion, false should definitely NOT match /./.

# cat false.pp 
$x = false
$y = $x ? {
/./ => 1,
false => 2,
default => 42,
notice( $x )
notice( $y )
# puppet apply false.pp 
notice: Scope(Class[main]): false
notice: Scope(Class[main]): 1

This is still true in Telly as it stands today. Pieter, I think you are the best placed person to drive the decision about what should happen here, and how it works. (Ultimately, this is because there are only strings in Puppet, not other data types, no matter how much it kind of looks like there are – or, at least, how we stringify types in a liberal fashion.)

Agree, a boolean value can not be matched with a regular expression. The Puppet DSL makes a distinction between false and “false” (the later is not boolean false, and neither is “true”).

This is a bug IMO.
