类 DidYouMean::MethodNameChecker

常量

NAMES_TO_EXCLUDE

RB_RESERVED_WORDS

MethodNameChecker::RB_RESERVED_WORDS 是 Ruby 中需要参数的保留字列表。与 VariableNameChecker::RB_RESERVED_WORDS 不同，这些保留字需要参数，并且由于参数的存在而引发 NoMethodError。

如果引发 NoMethodError 并找到最接近的匹配项，MethodNameChecker 将使用此列表建议使用反向字。

另请参阅 VariableNameChecker::RB_RESERVED_WORDS。
