paths

func Clean ¶

func Clean(path string) (string, error)

Clean returns the shortest path name equivalent to path by purely lexical processing. It applies the following rules iteratively until no further processing can be done:

1. Replace multiple slashes with a single slash.
2. Eliminate each . path name element (the current directory).
3. Eliminate each inner .. path name element (the parent directory) along with the non-.. element that precedes it.
4. Eliminate .. elements that begin a rooted path: that is, replace "/.." by "/" at the beginning of a path.

The returned path ends in a slash only if it is the root "/".

If the result of this process is an empty string, Clean returns the string ".".

func IsAbs ¶

func IsAbs(path string) bool

IsAbs reports whether the path is absolute.

func Join ¶

func Join(elem ...string) (string, error)

Join joins any number of path elements into a single path, separating them with slashes. Empty elements are ignored. The result is Cleaned. However, if the argument list is empty or all its elements are empty, Join returns an empty string.

func JoinTwoPath ¶

func JoinTwoPath(filePath string, relPath string) string
