MethodNameChecker::RB_RESERVED_WORDS
is the list of reserved words in Ruby that take an argument. UnlikeVariableNameChecker::RB_RESERVED_WORDS
, these reserved words require an argument, and aNoMethodError
is raised due to the presence of the argument.The
MethodNameChecker
will use this list to suggest a reversed word if aNoMethodError
is raised and found closest matches.Also see
