Replicator

Replicator is a class registry and factory.

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     replicator:
       github: first-try-software/replicator

2. Run shards install

Usage

require "replicator"

abstract class Starship
  extend Replicator::Replicable
end

class Enterprise < Starship
  replicates :galaxy
end

class Cerritos < Starship
  replicates :galaxy
end

Starship.replicate(:galaxy)  # => [#<Enterprise:0x1099ddd60>, #<Cerritos:0x1099ddd70>] : Array(Starship)

Roadmap

Replicator is ready to use in it's current state. The interfaces are unlikey to change. But, there will be new features added per our roadmap:

• Abstract classes can extend Replicator::Replicable to make their descendants "replicable"
• Concrete, "replicable" classes can self register under one or more keys by calling replicates :symbol
• Multiple concrete, "replicable" classes can self register under the same key by calling replicates :symbol
• Registered, "replicable" classes can be instantiated using the abstract parent's .replicate(:symbol) method
• Positional and named arguments may be passed when initializing "replicable" classes
• A "replicable" class may register as the default_replica for an extended abstract parent class, and will be instantiated when an unknown key is requested (good for the null object pattern)
• A "replicable" class may register as replicates_all in which case, it is always instantiated and returned in addition to the classes that match a requested key
