The complete solution for Ruby Configuration Management. RConfig is a Ruby library that manages configuration within Ruby applications. It bridges the gap between yaml, xml, and key/value based properties files, by providing a centralized solution to handle application configuration from one location. It provides the simplicity of hash-based access, that Rubyists have come to know and love, supporting your configuration style of choice, while providing many new features, and an elegant API.

• Simple, easy to install and use.

• Supports yaml, xml, and properties files.

• Yaml and xml files support infinite level of configuration grouping.

• Properties files support git config-like configuration grouping.

• Intuitive dot-notation ‘key chaining’ argument access.

• Simple well-known hash/array based argument access.

• Implements multilevel caching to reduce disk access.

• Short-hand access to ‘global’ application configuration, and shell environment.

• Overlays multiple configuration files to support environment and host-specific configuration.

• Onload callbacks for single, multiple, or any config file.

 shell/console =>
   export LANG=en

 demo.yml =>
  server:
    address: host.domain.com
    port: 81
  ...

 application.properties =>
   debug_level=verbose
 ...

demo.rb => 
 require 'rconfig'
 RConfig.config_paths = ['$HOME/config', '#{APP_ROOT}/config', '/demo/conf']
 RConfig.demo[:server][:port] => 81
 RConfig.demo.server.address  => 'host.domain.com'

 RConfig[:debug_level] => 'verbose'
 RConfig[:lang] => 'en'

• Ruby (Developed on 1.8.7)

• RubyGems (Developed on 1.3.5)

• activesupport (2.2.2+)

sudo gem install rconfig

1. Finish JSpecs for existing code (Yeah, I know. You’re supposed to right the JSpecs first.)

2. Create re-factor goals based on Caliper metrics.

3. Prep for cleaner, stabler release.

• Support for git-like config/properties files (You know, with the namespaced header blocks.).

• Support for Database-driven configuration.

• Removing dependency on ActiveSupport (Pull in needed code.).

• These are features I’m considering. E-mail me <[email protected]> If you like to see a feature added or expedited.

• None

Thanks to everyone I included here. RConfig would not exist without their contributions.
