module Chaintown
This module add ability to define chain of steps which will be called in order. Every step is a method in the class which include this module. Every class receive state and immutable params.
State
is used to keep information which will be shared between steps. State
should inherit from Chaintown::State
. Steps
are calls only when state is valid in other case invocation is stopped and moved to run steps defined as failed.
We can add conditions to step by using if parameter. We can also nest steps.
Example:
step :step1 step :step2, if: proc { |state, params| params[:run_step_2] } step :step3 do step :step4 end failed_step :step5
This module add DLS for defininig steps or failed_steps. All steps are of type Chaintown::Step
.
