Backload

Shouldn't loading have a callback?

Installation

Using RubyGems type on a command line:

$ gem install backload

Instruction

To use Backload simply override the Kernel.backloaded method.

  require 'backload'
  require 'backload/require_relative'

  def Kernel.backloaded(feature, options={})
    if options[:require]
      if rel = options[:relative]
        puts "#{feature} has been required relative to #{rel}!"
      else
        puts "#{feature} has been required!"
      end
    else
      if wrap = options[:wrap]
        puts "#{feature} has been loaded with wrap, it's #{wrap}!"  
      else
        puts "#{feature} has been loaded!" 
      end
    end
  end

Becuase of implementation details, #require_relative has to be reimplemented completely to make the callback work. To be on the safe side, at least for now, it therefore has to be required separately, as the example above demonstrates.

Backload also provides callbacks for each type of loading. Just use the past tense of the term for any of #load, #require and #require_relative. For example, to see all features as they have been required.

  def Kernel.required(feature)
    puts "#{feature} required!"
  end
