module SolidusSupport
# Compatibility middleman for {Spree::Event} and {Spree::Bus}
#
# Solidus v3.2 changed to use [Omnes](https://github.com/nebulab/omnes) as the
# backbone for event-driven behavior (see {Spree::Bus}) by default. Before
# that, a custom adapter based on {ActiveSupport::Notifications} was used (see
# {Spree::Event}. Both systems are still supported on v3.2.
#
# This module provides compatibility support so that extensions can easily
# target both systems regardless of the underlying circumstances:
#
# - Solidus v3.2 with the new system.
# - Solidus v3.2 with the legacy system.
# - Solidus v2.9 to v3.1, when only {Spree::Event} existed.
# - Possible future versions of Solidus, whether the legacy system is
# eventually removed or not.
module LegacyEventCompat
# Returns whether the application is using the legacy event system
#
# @return [Boolean]
