func NotExist ¶

func NotExist(src string) bool

NotExist reports whether nothing is at src.

It was called CheckExist and documented as checking existence while returning the opposite, so its one caller compensated by inverting twice. Renamed rather than corrected in place: a caller who had worked the real behaviour out gets a compile error instead of a silent inversion.

func Open ¶

func Open(name string, flag int, perm os.FileMode) (*os.File, error)

Open 打开文件

The caller owns the file and closes it. Closing it here — which a deferred call did — handed back a file that was already closed.

func PathExists ¶

func PathExists(path string) bool

func RemoveRepByMap ¶

func RemoveRepByMap(slc []string) []string

RemoveRepByMap returns slc without its duplicates, keeping first order.
