![]() Torm tries to follow Semantic Versioning 2.0.0, this means that given a version number, it will increment the: bundle install to install all development gems.Because rules are stored in order of priority, the first rule remaining is the one that applies the best.We gather all rules, then filter irrelevant rules based on environment conditions.Decisions take a rule and a bunch of environment conditions.Rationale: "We usually don't do this, except when it's summer." On equal policy level, more specific rules (more conditions) overrule less specific ones.Each condition must be met in order for a rule to be relevant.Rules have a set of zero or more conditions.Law (usually specific to a country) overrules everything.The Code of Conduct (usually specific to a country + payment method) overrules our policies and experiments.On top of defaults we can run experiments.decide ( 'Happy', country: 'NL' ) # => true How rules are evaluated add_rule 'Happy', true, :default engine. decide ( 'Happy', country: 'GB', rain: true ) # => true # If you need more rules engines, instantiate a non-global engine when you need one. decide ( 'Happy', country: 'NL', rain: true ) # => false Torm. decide ( 'Happy', country: 'NL' ) # => true Torm. variation false, :medium, umbrella_color: :red end end end end # Torm.instance holds the default engine used by t_defaults, so we can use it for making decisions. variation true, :high # Red umbrellas still make people grumpy, though. # People with an umbrella don't mind rain. variation true, :high, country: 'GB' rule. ![]() # Setup general conditions for the rest of the block rule. add_rules 'Happy', true, :default do | rule| priorities = # Add a new rule named 'Happy', with a value of true as 'default' policy engine.
