path/:name is a path of name located in a directory path. For example:

• PathType.root/:"var"/:"log" builds absolute path "/var/log"

• [user]/:".ssh" can be either:

  • absolute path "/.ssh" in case user is an empty string
  • relative path otherwise

PathType.default_validator is applied to the argument. name must not contain path separator (causes Illegal_char exception).

• raises Illegal_char

  (raised by validator on any bad character)

basepath//\@relpath catenates two paths.

Windows: As a special exception it is possible to pass absolute path as relpath, provided that basepath is simple absolute path (i.e. of the form [...; ""]) and relpath is not simple absolute path.

• raises Invalid_argument

  if the second argument is an absolute path (Windows: see above).
