Rubysierung

Rubysierung is the type system Ruby deserves

Installation

Add this line to your application's Gemfile:

# ruby 2.1.0

gem 'rubysierung'
gem 'CallBaecker', '~> 0.0.3'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rubysierung

Usage

Have a look at all available types in ./lib/rubysierung/types

require 'CallBaecker'
require 'rubysierung'

# define a custom type
class CustomType
end

class Example
  extend Rubysierung
  include CallBaecker # include Callbaecker after Rubysierung

  # if the type doesnt match Rubisierung will raise an Error messages

  # add custom Types
  # [TypeClass, StandartDuckTypeAsSymbol, StrictDuckTypeAsSymbol]# TODO change to proper name
  @__add_type[CustomTyp, :to_s, :to_str]

  # define foo to respond to :to_s and bar to :to_i
  def one(foo: String, bar: Integer)
    [foo, bar]
  end

  # you can still define empty/default parameters
  def self.three(foo: , bar: 'hallo World')
    [foo, bar]
  end

  # use a custom type
  def self.four(foo: ,bar: CustomType)
    [foo, bar]
  end

  # define foo to respond to :to_str (strict type)
  def self.five(foo: Strict::String, bar: Integer)
    [foo, bar]
  end
end

what would it look like normally

def one(foo:, bar:)
  sFoo = foo.to_s
  iBar = bar.to_i
  [sFoo, iBar]
end
