A general, non-filesystem-specific pathname library.
Returns just the basename of path, with any directory
removed. If path does not contain a directory separator,
return the whole path. If path ends in a directory
separator (i.e. path is a directory), or is empty, return the
empty string.
Returns just the directory of path.
If path is relative (or empty), return ".".
Returns the rightmost extension of path, not including the
".". If there is no extension, returns #f. The
extension will always be non-empty and contain no "."s.
Returns path with the extension, if any, removed,
along with the ".".
Returns path with the extension, if any, replaced
with ext.
Returns path with any leading ../ removed.
Returns #t iff path is an absolute path,
i.e. begins with "/".
Returns #t iff path is a relative path.
Returns the suffix of path relative to the directory
dir, or #f if path is not contained in
dir. If the two are the same (modulo a trailing
"/"), then "." is returned.
Resolve path relative to the given directory. Returns
path unchanged if already absolute.
Returns a normalized version of path, with duplicate directory
separators removed and "/./" and "x/../" references removed.
Does not take symbolic links into account - this is meant to
be abstract and applicable to paths on remote systems and in
URIs. Returns path itself if path is already
normalized.
Return a new string representing the path where each of args
is a path component, separated with the directory separator.
args may include symbols and integers, in addition to
strings.
