In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file `lib/conifer`. To experiment with that code, run `bin/console` for an interactive prompt. +Conifer allows you to easily manage YAML configuration files and import them into your Ruby objects. -TODO: Delete this and the text above, and describe your gem - ## Installation Add this line to your application's Gemfile: ```ruby @@ -20,20 +22,104 @@ $ gem install conifer ## Usage -TODO: Write usage instructions here +You can include the `Conifer` module in any class or module and specify the YAML file you want to import by calling the +`conifer` method: +```ruby +class Config + include Conifer + + conifer :config +end +``` + +By default, this will look for a file called `config.yml` in the same directory where the `Config` class is defined. +If no such file is found, it will look for that file in the parent directory. It will continue to traverse the ancestry +tree until it finds that file. If the file is not found, it will raise a `Conifer::File::NotFoundError` error. + +With the following `config.yml` file defined in the same directory as the source file for `Config`: + +```yaml +aws: + access_key_id: <%= ENV.fetch('AWS_ACCESS_KEY_ID', 'my-access-key-id') %> + bucket: atlantis +``` + +You may access the values using a method that defaults to the same name as your YAML file: + +```ruby +object = Config.new +object.config['aws.access_key_id'] #=> my-access-key-id +object.config['aws.bucket'] #=> atlantis +``` + +The `conifer` method accepts several optional keyword arguments: + +- `dir`: This option overrides the default location where the YAML file is expected to reside. +- `method`: This option overrides the default method name that is defined on the class or module. The method name defaults to the name of the YAML file. + ```ruby + class Config + include Conifer + + conifer :config, method: :foobar + end + ``` + + ```ruby + Config.new.foobar['aws.bucket'] #=> atlantis + ``` +- `prefix`: This is a string that will be prepended to the lookup key. This is especially useful in Rails where you would like to have different values per environment. + ```ruby + class Config + include Conifer + + conifer :config, prefix: Rails.env + end + ``` + + With the following `config.yml` file: + + ```yaml + development: + aws: + bucket: atlantis-development + + production: + aws: + bucket: atlantis-production + ``` + + You can lookup the values the same as before: + + ```ruby + Rails.env #=> development + Config.new.config['aws.bucket'] #=> atlantis-development + ``` +- `singleton`: This is `false` by default. When set to `true`, the method will be defined at the class scope instead of the instance scope. + ```ruby + class Config + include Conifer + + conifer :config, singleton: true + end + ``` + + ```ruby + Config.config['aws.bucket'] #=> atlantis + ``` + ## Development After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment. To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org). ## Contributing -Bug reports and pull requests are welcome on GitHub at https://github.com/[USERNAME]/conifer.
