Functions

func FileExists

func FileExists(path string) (bool, error)

func GlobMatch

func GlobMatch(key1 string, key2 string) (bool, error)

GlobMatch determines whether key1 matches the pattern of key2 using glob pattern

func GlobMatchFunc

func GlobMatchFunc(args ...interface{}) (interface{}, error)

GlobMatchFunc is the wrapper for GlobMatch.

func Hash
