Evaluation Error: Unknown function: 'has_key' in install.pp

[slauger]

This module does no longer work with the current version of puppetlabs-stdlib.

In this MR the has_key function was removed.

puppetlabs/puppetlabs-stdlib#1319

Is this repository still managed? Would you accept a pull request? Or maybe this module can be transfered to voxpupuli team?

Quick and dirty fix for this: add a file lib/puppet/parser/functions/has_key.rb with the following content.

# frozen_string_literal: true

#
# has_key.rb
#
module Puppet::Parser::Functions
  newfunction(:has_key, type: :rvalue, doc: <<-'DOC') do |args|
    @summary
      **Deprecated:** Determine if a hash has a certain key value.
    @return
      Boolean value
    @example Example Usage:
      $my_hash = {'key_one' => 'value_one'}
      if has_key($my_hash, 'key_two') {
        notice('we will not reach here')
      }
      if has_key($my_hash, 'key_one') {
        notice('this will be printed')
      }
    > **Note:** **Deprecated** since Puppet 4.0.0, this can now be achieved in the Puppet
    language with the following equivalent expression:
    $my_hash = {'key_one' => 'value_one'}
    if 'key_one' in $my_hash {
      notice('this will be printed')
    }
    DOC

    unless args.length == 2
      raise Puppet::ParseError, "has_key(): wrong number of arguments (#{args.length}; must be 2)"
    end
    unless args[0].is_a?(Hash)
      raise Puppet::ParseError, "has_key(): expects the first argument to be a hash, got #{args[0].inspect} which is of type #{args[0].class}"
    end
    args[0].key?(args[1])
  end
