Function clean

clean(path): string

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:

Replace multiple [Separator] elements with a single one.
Eliminate each . path name element (the current directory).
Eliminate each inner .. path name element (the parent directory)

along with the non-.. element that precedes it.Copy

Eliminate .. elements that begin a rooted path:

that is, replace "/.." by "/" at the beginning of a path, assuming Separator is '/'.Copy

The returned path ends in a slash only if it represents a root directory, such as "/" on Unix or C:\ on Windows.

Finally, any occurrences of slash are replaced by Separator.

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

On Windows, Clean does not modify the volume name other than to replace occurrences of "/" with ``. For example, Clean("//host/share/../x") returns \\host\share\x.
