For example: $foo = getvar('site::data::foo') # Equivalent to $foo = $site::data::foo This is useful if the namespace itself is stored in a string: $datalocation = 'site::data' $bar = getvar("${datalocation}::bar") # Equivalent to $bar = $site::data::bar ENDHEREDOC unless args.length == 1 raise Puppet::ParseError, ("getvar(): wrong number of arguments (#{args.length}; must be 1)") end begin self.lookupvar("#{args[0]}") rescue Puppet::ParseError # Eat the exception if strict_variables = true is set end end end
