Includes:
Scorpion::Object
Defined in:
lib/shamu/features/conditions/proc.rb

Overview

Match against a custom method. Due to their dynamic nature, proc conditions are much slower and should be reserved for only a few features.

The proc is specified in the configuration by class and method name like

# features.yml
commerce:
  buy_now:
    select:
    - proc: Commerce::BuyNow#match?

Shamu will instantiate a new instance of the Commerce::BuyNow class and invoke the match? method passing the current Shamu::Features::Context.

The custom proj will also have access to the current Scorpion if it includes the Scorpion::Object mixin.
