Replace macro fields with Ruby

OK, now let's do it in Ruby. This requires a values.rb folder (like our values.ps1 folder in powershell):

require 'erb'
require 'rio'

module MacroConfig

def self.generate
  mkdir_if_not_exist 'configs'

  Dir.glob('templates/*').each do |template_file|
    template = ''
    rio(template_file) > template
    config = ERB.new(template).result(get_values)

    config_file = 'configs/' + File.basename(template_file)
    rio(config_file) < script =" ''">> script
    script << "\n"
  end

  eval script
  binding
end

def self.get_values
  read_values(['../values.rb', 'values.rb'])
end

def self.mkdir_if_not_exist(dir_name)
  Dir.mkdir dir_name unless File.exist? dir_name
end

end
