SelfData

It's like native ruby DATA but you can use it not only for main file.

For example:

# main.rb

require 'self_data'
require './a.rb'

puts "DATA: #{A.native_data}"
puts "SelfData: #{A.self_data}"

__END__

# a.rb

module A
  module_function

  def native_data
    DATA.read
  end

  def self_data
    SelfData.read
  end
end

__END__

and if you execute it, you'll get:

$ ruby main.rb
DATA: main.rb data
SelfData: a.rb data

Usage

Use SelfData.read() to get text or use SelfData.load(*formats, **options) to get formatted data (like yaml, xml, erb, etc).

Look at the lib/self_data/config.rb for more details.

Note

SelfData use caller, it's not fast, that is why you shouldn't use SelfData in loops.
