NxtErrorRegistry

Register all your errors in a sane way.

Installation

Add this line to your application's Gemfile:

gem 'nxt_error_registry'

And then execute:

$ bundle

Or install it yourself as:

$ gem install nxt_error_registry

Usage

class LevelOne
  extend NxtErrorRegistry
  register_error :LevelOneError, type: StandardError, code: '84b67c94-efb4-48e8-a5e9-ed1fa1beb988'
  # This will set the LevelOne::LevelOneError constant that you can raise anywhere
  register_error :LevelTwoError, type: LevelOneError, code: 'a7fc9a8c-9f83-4a2d-8808-75dbef8e376f', capture: true, reraise: false
  # You can also pass in additional options when registering your errors. These will be available on you error class 
  
  def raise_level_one_error
    raise LevelOneError, 'There was an error on level'
  rescue LevelOneError => e
    puts e.code # would output '100.100'
  rescue LevelTwoError => e
    puts e.options # { capture: true, reraise: false } 
  end
end

register_error will make sure that the code was not already registered anywhere else in your app.

Generate an register_error statement to include in your code with the rails generator
