Transproc

Functional transformations for Ruby. It's currently used as one of the data mapping backends in Ruby Object Mapper.

Installation

Add this line to your application's Gemfile:

gem 'transproc'

And then execute:

$ bundle

Or install it yourself as:

$ gem install transproc

Usage

require 'transproc/all'

# compose transformation functions
transformation = Transproc(:symbolize_keys) + Transproc(:map_hash, user_name: :name))

# call the function
transformation['user_name' => 'Jane']
# => {:name=>"Jane"}

# or using a helper (no, it's not a good idea to include it here :))
include Transproc::Composer

transformation = compose do |fns|
  fns << t(:symbolize_keys) << t(:map_hash, user_name: :name)
end

transformation['user_name' => 'Jane']
# => {:name=>"Jane"}
