Module: Pliny::ConfigHelpers

Defined in:
lib/pliny/config_helpers.rb

Overview

DEPRECATED: ConfigHelpers was a slightly more primitive version of CastingConfigHelpers above that didn’t contain any of the latter’s features around typing. It’s been left here for backwards compatibility in apps based on old templates that may be using it.
