= Konfigurator
Konfigurator is a small and flexible configuration toolkit, which allow you to configure your apps, classes or modules with DSL-style or Sinatra-like settings.
== Installation
You can install Konfigurator simply using rubygems:
sudo gem install konfigurator
...or install it from source:
git clone git://github.com/nu7hatch/konfigurator.git cd konfigurator rake install
== Sinatra-like configuration
Konfigurator is very easy to use. Take a look at simple example.
class MyClass do include Konfigurator
set :foo, "bar"
enable :bar
disable :bla
configure :production do
enable :bla
set :spam, "eggs!"
end
end
Now you can get configured options directly from your class:
MyClass.foo # => "bar" MyClass.bar # => true MyClass.bla # => false
... or when current environment is set to <tt>:production</tt>:
MyClass.bla # => true MyClass.spam # => "eggs!"
All settings are also available from objects via <tt>#settings</tt> method:
obj = MyObject.new obj.settings.foo # => "bar" obk.settings.bar # => true
<b>Remember!</b> when option is not set then <tt>NoMethodError</tt> will be raised after try to get it direcly from class, eg:
MyObject.set :exist MyObject.exist # => true MyObject.not_exist # => will raise NoMethodError
== DSL-style configuration
Not there is also possible to use nice-looking DSL syntax provided by <tt>Konfigurator::DSL</tt>. It allow you to configure your apps/classes such like here:
Foo.configure do host "127.0.0.1" port 8080 password "secret" end
But what's important in this kind of configuration, you have to define all possible options first. You can define configuration attributes easy using <tt>#attr_config</tt> (or <tt>#attr_setting</tt> alias).
class Foo include Konfigurator::DSL
attr_config :host, :port
attr_config :password
end
Other use cases behave almost the same as with Konfigurator::Simple:
Foo.host # => "127.0.0.1" Foo.port # => 8080
Foo.env :production Foo.configure :production do host "production.com" port 80 end
foo = Foo.new foo.settings.host # => "production.com" foo.settings.port # => 80
== Configuring Rails 3 application
You can easily mix Konfigurator with your Rails 3 app. Add this line to your <tt>config/application.rb</tt>:
require 'konfigurator/railtie'
... and now you can set your own configuration, eg:
module MyApp class Application < Rails::Application set :foo, "Foo" set :bat, "Bar" enable :foobar
# ...
end
end
Now you can use it in controllers...
class UsersController def index if settings.foobar and settings.foo == "Foo" # ... end end end
... and views...
<h1><%= settings.foo %></h1> <p><%= settings.bar %></p>== Note on Patches/Pull Requests
- Fork the project.
- Make your feature addition or bug fix.
- Add tests for it. This is important so I don't break it in a future version unintentionally.
- Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
- Send me a pull request. Bonus points for topic branches.
