ruby-conf

Simple way to do ruby config DSL

Install

gem install ruby-conf

Gemfile

gem "ruby-conf"

Examples

RubyConf.define :godzilla do
mothra 'sucks'
godzilla 'rocks'
end


> RubyConf.godzilla.mothra
=> "sucks" 
> RubyConf.godzilla.godzilla
=> "rocks" 


RubyConf.define "monkey" , :as => 'MyBonobo' do
has_legs true
number_arms 2
number_legs 2
name 'Nancy' , 'Drew'
age 34

# make sure to pass a lambda and not a do block
# do blocks chain configurations (see below)
number_of_bananas_eaten lambda { 
 BanannaChomper.lookup("nancy.bananas").count
}
end
MyBonobo.name                     # ['Nancy' , 'Drew']
MyBonobo.number_of_bananas_eaten  # execute proc
MyBonobo.number_legs              # 2
RubyConf[:monkey][:age]           # 34
...

Anonymous configurations

config = RubyConf.define do favorite_color 'blue' end config.favorite_color # "blue"

Configuration chaining

RubyConf.define "rails", :as => :RailsConfig do production do database "rails_prod" host "localhost" end staging do database "rails_staging" host "localhost" end end RailsConfig.production.database # "rails_prod" RailsConfig.staging.database # "rails_staging"

Inheritance

RubyConf.define "rails", :as => :RailsConfig do defaults do host "localhost" username "godzilla" password "mothra" end

development :inherits => defaults do
  database "development"
end

test :inherits => defaults do
  database "test"
  username "biollante"
  password "destroygodzilla"
end

production :inherits => defaults do
  database "production"
  host "killmothra.net"
  password "ilovemothra"
end
end
RailsConfig.development.database      # "development"
RailsConfig.development.username      # "godzilla
RailsConfig.development.password      # "mothra"
RailsConfig.production.username       # "godzilla"
RailsConfig.production.password       # "ilovemothra"

Contributing to ruby-conf

  • Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
  • Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
  • Fork the project.
  • Start a feature/bugfix branch.
  • Commit and push until you are happy with your contribution.
  • Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
  • Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
