Module: RSpecTracer::Configuration::DslTypoSuggester

Defined in:
lib/rspec_tracer/configuration.rb

Overview

Helpers for the DSL-typo did you mean surface. Lives in a dedicated module so its methods stay outside the configure-time alias_method :"_#{name}" wrapper loop in Configuration#configure (which iterates Configuration's private_instance_methods(false) twice during load_default_config + load_local_config and would double-alias any helper instance methods we kept here).
