module Puppet::Parser::Functions
newfunction(:validate_nonemptyarray, :doc => <<-'ENDHEREDOC') do |args|
Validate that all passed values are array data structures. Abort catalog
compilation if any value fails this check. Also abort if any of the arrays
is empty.
The following values will pass:
$my_array = [ 'one', 'two' ]
validate_nonemptyarray($my_array)
The following values will fail, causing compilation to abort:
validate_nonemptyarray(true)
validate_nonemptyarray([])
validate_nonemptyarray('some_string')
$undefined = undef
validate_nonemptyarray($undefined)
ENDHEREDOC
unless args.length > 0 then
raise Puppet::ParseError, ("validate_nonemptyarray(): wrong number of arguments (#{args.length}; must be > 0)")
end
args.each do |arg|
unless arg.is_a?(Array)
raise Puppet::ParseError, ("#{arg.inspect} is not an Array. It looks to be a #{arg.class}")
end
unless arg.length > 0
raise Puppet::ParseError, ("#{arg.inspect} is an empty Array.")
end
