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
