Ruby Quirks

For Ruby 1.9.3, 2.0.x, 2.1.x, 2.2.x

Introduction

ruby_quirks is a gem which adds a collection of optional Ruby hotfixes and common idioms to accommodate for some of Ruby's quirky behaviors. See the list below to see what's offered.

Hotfixes

Hash#reject and Hash#select returns Hash for subclasses of Hash

• For Ruby versions: 2.2.0+
• Description: Calling #reject or #select against an instance of a class that inherits from Hash will return an object of type Hash, rather than an object of the same type that #reject or #select was called against. e.g. This broke Rails' HashWithIndifferentAccess. See this question for more details.
• What this hotfix does: It overrides #reject and #select of implementing classes to use #dup to return an object of the same type. This effectively replicates pre-2.2 behavior of Hash.
• How to implement: Include the RubyQuirks::Hash::EnumByDup in your class that inherits from Hash

• Example:

  module CustomHash < Hash
    include RubyQuirks::Hash::EnumByDup
  end
