benry-config

($Release: 0.1.0 $)

Overview

Utility class to support configuration.

Easy to define configuration for environments (production, development, ...).
Raises error when configuration name is wrong (typo).
Represents secret configurations which should be set in private file.

Example

#----- config/common.rb -----
require 'benry/config'
class CommonConfig < Benry::BaseConfig
  add :db_user            , "user1"
  add :db_pass            , ABSTRACT
  add :session_cooie      , "sess"
  add :session_secret     , SECRET
end

#----- config/development.rb -----
require 'config/common'
class Config < CommonConfig
  set :db_pass            , "pass1"
end

#----- config/development.private -----
Config.class_eval do
  set :session_secret     , "abc123"
end

#----- main.rb -----
## Ruby < 2.2 has obsoleted 'Config' class, therefore remove it at first.
Object.class_eval { remove_const :Config } if defined?(Config)
#
rack_env = ENV['RACK_ENV']  or raise "$RACK_ENV required."
require "./config/#{rack_env}.rb"
load    "./config/#{rack_env}.private"
#
$config = Config.new.freeze
p $config.db_user             #=> "user1"
p $config.db_pass             #=> "pass1"
p $config.session_cookie      #=> "sess"
p $config.session_secret      #=> "abc123"
#
p $config.get_all(:db_)       #=> {:user=>"user1", :pass=>"pass1"}
p $config.get_all(:session_)  #=> {:cookie=>"sess", :secret=>"abc123"}
