# SelfData

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

For example:
```ruby
# main.rb

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

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

__END__
main.rb data
```

```ruby
# a.rb

module A
  module_function

  def native_data
    DATA.read
  end

  def self_data
    SelfData.read
  end
end

__END__
a.rb data
```

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](https://github.com/umbrellio/self_data/blob/master/lib/self_data/config.rb) for more details.

# Note
SelfData uses `caller`, it's not fast, that's why you shouldn't use SelfData in loops.
