logcabin

Support dynamic loading of modules at runtime

Create a collection of modules with collection = LogCabin.new(load_path: '/path/to/modules').

You can also pass in an array of paths as load_path.

You can then load a module and return it with collection.find(:module_name) (you can use a string or symbol for the name).

Modules should be children of LogCabin::Modules, like so:

module LogCabin
  module Modules
    module MyDynamicModule
      def useful_function
        puts "Hello world"
      end
    end
  end
end

This should go in the file "my_dynamic_module.rb", and would be loaded with collection.find(:my_dynamic_module). This naming convention is required for modules, where an underscore in the filename matches with a capitalized letter in the module definition.

As an example usage, you can use LogCabin to dynamically extend instances of a class:

COLLECTION = LogCabin.new(load_path: '/path/to/my/dynamic/module')

class BoringClass
  def initialize(cool_module)
    extend COLLECTION.find(cool_module)
  end
end

x = BoringClass.new('my_dynamic_module')
x.useful_function >> puts "Hello World"
