module PuppetfileFixturesGenerator

Writes a YAML file conforming to [puppetlabs_spec_helper's] (github.com/puppetlabs/puppetlabs_spec_helper) fixtures file format based off a provided Puppetfile.

@author Alejandro Figueroa

@param [String] puppetfile The path, local or absolute, to the

Puppetfile. This Puppetfile will be loaded and parsed to create
the fixtures YAML file.

@param [String] fixtures_yml The path, local or absolute, to the

fixtures file to be written. The path, not the file, must exist.

@param [String] symlink_name The name of the module to include as

the source_dir symlink in the fixtures file.

@return The fixtures file specified as a parameter.

# File lib/puppetfile_fixtures_generator.rb, line 27
def self.create_fixtures(puppetfile = nil, fixtures_yml = './.fixtures.yml', symlink_name = nil)
  modules = nil

  unless puppetfile.nil?
    pf = PuppetfileFixturesGenerator::Puppetfile.new(puppetfile)
    modules = pf.modules_hash
  end

  # write fixtures
  fixtures = PuppetfileFixturesGenerator::Fixtures.new(fixtures_yml, modules, symlink_name)
  fixtures.write
end

Takes a puppetfile and a fixtures file, converts themk to hashes, diffs the hashes, and returns the results.

@param [String] puppetfile The path, local or absolute, to the

@param [String] fixtures The path, local or absolute, to the

fixtures file to be written. The path, not the file, must exist.

@return [Array] The results of self.hash_differ

# File lib/puppetfile_fixtures_generator.rb, line 50
def self.diff(puppetfile, fixtures)
  pf = PuppetfileFixturesGenerator::Puppetfile.new(puppetfile)
  fx = PuppetfileFixturesGenerator::Fixtures.new(fixtures)

  pf_modules = pf.modules_hash['repositories'].to_a
  fx_modules = fx.modules_hash['fixtures']['repositories'].to_a

  hash_differ(pf_modules, fx_modules)
end

Takes two hashes, diffs them, and returns results

@param hash1 [Hash] First hash to diff @param hash2 [Hash] Second hash to diff

@return [Array] First element in array is a boolean for whether

the files had differences. Second element is a hash of
differences.

# File lib/puppetfile_fixtures_generator.rb, line 70
def self.hash_differ(hash1, hash2)
  result = hash1 == hash2
  return [result, {}] if result
  [result, Hash[*(hash2.size > hash1.size ? hash2 - hash1 : hash1 - hash2).flatten]]
end
