Aktualizacja 2012 : Naprawdę polecam teraz wypróbowanie vim-powerline, który zastąpił mój stary skrypt linii statusu, chociaż obecnie brakuje mi kilku funkcji, których brakuje.
Powiedziałbym, że rzeczy dotyczące linii statusu w moim vimrc były prawdopodobnie najbardziej interesujące / przydatne z całej masy (zgrane z vimrc autorów tutaj i odpowiadający im post na blogu tutaj ).

Między innymi informuje w linii stanu o zwykłych standardowych informacjach o pliku, ale zawiera również dodatkowe rzeczy, takie jak ostrzeżenia dla: ustaw wklejania, mieszane wcięcia, końcowe białe znaki itp. Całkiem przydatne, jeśli jesteś szczególnie zainteresowany formatowaniem kodu.
Ponadto, jak pokazano na zrzucie ekranu, połączenie go ze
składnią pozwala na wyróżnienie wszelkich błędów składniowych (zakładając, że wybrany język ma dołączony moduł sprawdzania składni.
