module Puppet::Parser::Functions
newfunction(:loadjson, :type => :rvalue, :arity => -2, :doc => <<-'DOC') do |args|
Load a JSON file containing an array, string, or hash, and return the data
in the corresponding native data type.
The second parameter is the default value. It will be returned if the file
was not found or could not be parsed.
For example:
$myhash = loadjson('/etc/puppet/data/myhash.json')
$myhash = loadjson('no-file.json', {'default' => 'value'})

raise ArgumentError, 'Wrong number of arguments. 1 or 2 arguments should be provided.' unless args.length >= 1
if File.exists?(args[0]) # rubocop:disable Lint/DeprecatedClassMethods : Changing to .exist? breaks the code
begin
content = File.read(args[0])
PSON.load(content) || args[1]
rescue StandardError => e
raise e unless args[1]
args[1]
end
else
warning("Can't load '#{args[0]}' File does not exist!")
