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).
