split-path

[procedure] split-path path

MzScheme: decompose pathname and returns three values, base, name and must-be-dir?.

• base may be:
  • a string pathname
  • 'relative
  • #f (if path is a root dir)
• name may be:
  • a string dir name
  • a string file name
  • 'up if the last component is up-directory (..)
  • 'same if the last component is same-directory (.)
• must-be-dir?
  • #t if path explicitly specifies a directory
  • #f otherwise

Chicken has decompose-pathname, which is somewhat similar to this function.
