Gem which helps initialize class instance with .call method.

.call(*args) => #new.call(*args)

Add this line to your application's Gemfile:

gem 'caller'

And then execute:

$ bundle

Or install it yourself as:

$ gem install caller

Do you have some code like this?

module Service
  def call(*args)
    new(*args).call
  end
end

class Printer
  extend Service

  def initialize(text)
    @text = text
  end

  def call
    @text
  end
end

Let's replace it with caller

class Printer
  extend Caller

  def call(text)
    text
  end
end

Printer.call('Say caller')

Assign other alias for the constructor with caller_for method

class Printer
  extend Caller

  caller_for :print

  def print(text)
    text
  end
end

Printer.print('Say caller')
