用英語命名標識符。
# bad - identifier using non-ascii characters заплата = 1_000 # bad - identifier is a Bulgarian word, written with Latin letters (instead of Cyrillic) zaplata = 1_000 # good salary = 1_000
使用snake_case的形式給變量和方法命名。
# bad :'some symbol' :SomeSymbol :someSymbol someVar = 5 def someMethod ... end def SomeMethod ... end # good :some_symbol def some_method ... end
Snake case: punctuation is removed and spaces are replaced by single underscores. Normally the letters share the same case (either UPPER_CASE_EMBEDDED_UNDERSCORE or lower_case_embedded_underscore) but the case can be mixed
