I am trying to develop a provider that will query the system for my custom resource myfile. However when I run
puppet resource myfile --environment tap --debug I get the following results:

Debug: Runtime environment: puppetversion=4.5.3, rubyversion=2.1.9, runmode=user, defaultencoding=UTF-8
Debug: Executing: '/bin/ls /folders'
Debug: #each property -> {:ensure=>:present, :name=>"/folders/otherfile", :owner=>"root"}
Debug: #each property -> {:ensure=>:present, :name=>"/folders/testf", :owner=>"root"}
myfile { '/folders/otherfile':
ensure => 'present',
myfile { '/folders/testf':
ensure => 'present',

This looks good except it is missing my owner property that I am also searching for. My provider is below:

Puppet::Type.type(:myfile).provide(:ruby) do
    commands :touch => 'touch', :ls => 'ls'


def self.get_list_of_myfiles
  files = ls('/folders')
  files = files.gsub(/\s+/m, ' ').strip.split(" ")

def self.get_properties(file)
properties = {}

  output = `ls -l /folders/#{file}`
rescue Puppet::ExecutionFailure => e
  Puppet.debug "#get_properties had an error -> #{e.inspect}"
  return {}

output = output.gsub(/\s+/m, '::').strip.split("::")
#     0      1  2    3   4  5  6    7      8
#-rw-r--r-- 1 root root 0 Dec 30 07:28 /folders/otherfile

properties[:ensure] = :present
properties[:name] = output[8]
properties[:owner] = output[2]

def self.instances
get_list_of_myfiles.collect do |each|
  properties = get_properties(each)
  Puppet.debug "#each property -> #{properties}"

Why is my owner field missing?

Use stat(1) for a scripted approach: /usr/bin/stat -c '%U' <filename>; For a programed approach use ruby's File class https://ruby-doc.org/core/File/Stat.html#method-i-uid The latter will be definitely more clean.

I am not sure what you are telling me to do, neither of these is going to make my owner field be displayed when doing a puppet resource myfile. I need all of the properties of any of my custom resource types be displayed when someone does a puppet resource [myresource]

Why are you defining self.get_list_of_myfiles twice?
