Now accepts arrays :)
Broke my spec tests :(
Error codes changedslightly
Broke my spec tests :(
expected Puppet::Error withmessage matching /^true isnot a string/, got
#<Puppet::Error: EvaluationError: Error whileevaluating a Function Call,true is not a string. Itlooks to be a TrueClass
Got rid of '^' in regex so it was notbeing as explicit.
Templates
Must have @var instead of just var.
Check inline_template() too.
Stop using inline_template()
