Class Method Details

.all_scripts(dir, opts = {}) {|path| ... } ⇒ Object

Execute an action for all scripts within a directory.

Parameters:

  • dir (String) —

    Directory containing `.rb` scripts.

  • opts (Hash) (defaults to: {}) —

    ({}) Configuration options.

Options Hash (opts):

  • :except (Array) — default: nil —

    Literal file collection excluded from process.

Yield Parameters:

  • path (String) —

    Script file path.

  excluded_files = (opts[:except] || []).map{|f|File.expand_path File.join(dir, f)}
  files = Dir[File.join(File.expand_path(dir), '*.rb')] - excluded_files
  block ||= proc{}
  files.sort.each &block
end

.analyze_compatibility(source, fragment) ⇒ Hash

Generate a compatibility report from a source and a fragment as a hash.

Examples:

Analyze when uncompatible `fragment` because of `source` missing fields.

AeEasy::Core.analyze_compatibility [1,2,3,4,5], [1,2,6]
# => {missing: [6], new: [3,4,5], is_compatible: false}

Analyze when compatible.

AeEasy::Core.analyze_compatibility [1,2,3,4,5], [1,2,3]
# => {missing: [], new: [4,5], is_compatible: true}

Parameters:

  • source (Array) —

    Item collection to represent the universe.

  • fragment (Array) —

    Item collection to compare againt source.

Returns:

  • (Hash) —

    • `:missing [Array]` (`[]`) Methods on `fragment` only.

    • `:new [Array]` (`[]`) Methods on `source` only.

    • `:is_compatible [Boolean]` true when all `fragment`'s methods are present on `source`.

  }
end

.deep_clone(hash, should_clone = false) ⇒ Hash

    Hash to clone.

  • should_clone (Boolean) (defaults to: false) —

    (false) Clone values when true.

Returns:

  • (Hash) —

Examples:

class Foo
  def hello_person
    'Hello person!'
  end
end

env = {
  hello_world: lambda{return 'Hello world!'},
  hello_sky: proc{return 'Hello sky!'}
}
my_object = Foo.new
AeEasy::Core.expose_to my_object, env

puts my_object.hello_world
# => 'Hello world!'
puts my_object.hello_sky
# => 'Hello sky!'
puts my_object.hello_person
# => 'Hello person!'

Parameters:

  • object —

    Object instance to expose env into.

  • env (Array) —
