NamespaceHelper

Build Status Code Climate

Description

NamespaceHelper is a Ruby library providing a module with methods to ease namespace handling. For example getting the unprefixed name, the namespace parent or a list of namespace components of a class or module.

Features / Problems

This project tries to conform to:

Additional facts:

  • Written purely in Ruby.
  • Documented with YARD.
  • Intended to be used with Ruby 1.8.7 or higher.
  • Extends core classes. This can be disabled through bare mode.
  • Cryptographically signed gem and git tags.

Synopsis

This documentation defines the public interface of the software. Don't rely on elements marked as private. Those should be hidden in the documentation by default.

Loading

In most cases you want to load the library by the following command:

require 'namespace_helper'

In a bundler Gemfile you should use the following:

gem 'namespace_helper'

By default, NamespaceHelper extends the Class and Module classes to allow make all classes and modules support the namespace helper methods. Should you really don't want this, use the following:

require 'namespace_helper/bare'

Or for bundler Gemfiles:

gem 'namespace_helper', require: 'namespace_helper/bare'

Usage

In normal mode, you can now ask every class or module namespace related stuff:

Process::Status.namespace_components
# => [Process, Process::Status]

Process::Status.namespace_component_names
# => ["Process", "Process::Status"]

Process::Status.unprefixed_namespace_component_names
# => ["Process", "Status"]

See {Aef::NamespaceHelper::ClassMethods} for a list of available methods.

If you're using the bare mode, you have to manually extend a class or module for which you require namespace information:

File::Constants.extend(Aef::NamespaceHelper::ClassMethods)

File::Constants.unprefixed_name
# => "Constants"

File::Constants.namespace_parent
# => File

File::Constants.namespace_parent_name
# => "File"

Requirements

  • Ruby 1.8.7 or higher

Installation

On *nix systems you may need to prefix the command with sudo to get root privileges.

High security (recommended)

There is a high security installation option available through rubygems. It is highly recommended over the normal installation, although it may be a bit less comfortable. To use the installation method, you will need my gem signing public key, which I use for cryptographic signatures on all my gems.

Add the key to your rubygems' trusted certificates by the following command:

gem cert --add aef-gem.pem

Now you can install the gem while automatically verifying it's signature by the following command:

gem install namespace_helper -P HighSecurity

Please notice that you may need other keys for dependent libraries, so you may have to install dependencies manually.

Normal

gem install namespace_helper

Automated testing

Go into the root directory of the installed gem and run the following command to fetch all development dependencies:

bundle

Afterwards start the test runner:

rake spec

If something goes wrong you should be noticed through failing examples.

Development

Bug reports and feature requests

Please use the issue tracker on github.com to let me know about errors or ideas for improvement of this software.

Source code

This software is developed in the source code management system Git. There are several synchronized mirror repositories available:

You can get the latest source code with the following command, while exchanging the placeholder for one of the mirror URLs:

git clone MIRROR_URL

Tags

The final commit before each released gem version will be marked by a tag named like the version with a prefixed lower-case "v", as required by Semantic Versioning. Every tag will be signed by my OpenPGP public key which enables you to verify your copy of the code cryptographically.

Add the key to your GnuPG keyring by the following command:

gpg --import aef-openpgp.asc

This command will tell you if your code is of integrity and authentic:

git tag -v [TAG NAME]

Contribution

Help on making this software better is always very appreciated. If you want your changes to be included in the official release, please clone my project on github.com, create a named branch to commit and push your changes into and send me a pull request afterwards.

Please make sure to write tests for your changes so that I won't break them when changing other things on the library. Also notice that I can't promise to include your changes before reviewing them.
