Sorta-lens

Simple lensing for your data extraction needs

Installation

Add it to your gemfile:

gem 'sorta-lens', '~> 0.1.0'

or install globally for use in scripts or IRB

gem install sorta-lens

Usage

Simply instantiate a Lens and start applying it to your objects:

  complex1 = { id: 451, .... status: :active }
  complex2 = User.first # has property `id` and method `status`
  lens = Sorta::Lens.on :id, :status
  lens.(complex1) # => { id: 451, status: :active }
  lens.(complex2) # => { id: 1, status: :online }

There is also a typed version:

  complex1 = { id: 451, .... status: :active }
  complex2 = { id: 9001, .... status: "online" }
  lens = Sorta::Lens.typed.on id: Integer, status: String
  lens.(complex1) # => TypedLens::TypeError (Unexpected type. Expected String got Symbol)
  lens.(complex2) # => { id: 9001, status: "online" }
