Hashy

Build Status

A trivial implementation of three new Hash methods: map_pair, map_key & map_value. It's been proposed that these methods be added to the Ruby language. They're each just one-liners in Ruby but it seems they're quite handy.

Installation

gem install hashy

Usage

require 'hashy'

hash = { aim: true }
#=> {:aim=>true}

hash.map_pair { |k, v| [k.to_s, v.to_s] }
#=> {"aim"=>"true"}

hash.map_key(&:to_s)
#=> {"aim"=>true}

hash.map_value(&:to_s)
#=> {:aim=>"true"}
