Description

OpenNamespace allows namespaces to require and find classes and modules from RubyGems. Using OpenNamespace you can make a Plugins module able to load plugin modules/classes from other gems.

Features

• Provides implicit loading of constants via const_defined?.
• Provides implicit loading of constants via const_missing.
• Provides explicit loading of constants via require_const.
• Can auto-load other sub-gems (ex: foo-bar) from the main gem's namespace (ex: Foo).

Examples

Include it into a namespace:

require 'open_namespace'

module Project
  module Plugins
    include OpenNamespace
  end
end

Explicitly load constants via their file name:

Project::Plugins.require_const :foo_bar
# => Project::Plugins::FooBar

Explicitly load constants containing uppercase acronyms:

Project::Plugins.require_const :tcp_session
# => Project::Plugins::TCPSession

Explicitly load constants from nested directories:

Project::Plugins.require_const 'templates/erb'
# => Project::Plugins::Templates::Erb

Implicitly load constants via const_missing:

Project::Plugins::Other
# => Project::Plugins::Other

Loading constants from alternate namespace root directories:

module Project
  module UI
    module CommandLine
      module Commands
        include OpenNamespace

        self.namespace_root = File.join(__dir__,'commands')
      end
    end
  end
end

Project::UI::CommandLine::Commands.require_const :help
# => Project::UI::CommandLine::Commands::Help
