namestring, file-namestring, directory-namestring, host-namestring, enough-namestringFunction


    namestring pathname namestring

    file-namestring pathname namestring

    directory-namestring pathname namestring

    host-namestring pathname namestring

    enough-namestring pathname &optional defaults namestring

    Arguments and Values

    pathname — a pathname designator.

    defaults — a pathname designator. The default is the value of *default-pathname-defaults*.

    namestring — a string or nil.


    These functions convert pathname into a namestring. The name represented by pathname is returned as a namestring in an implementation-dependent canonical form.

    namestring returns the full form of pathname.

    file-namestring returns just the name, type, and version components of pathname.

    directory-namestring returns the directory name portion.

    host-namestring returns the host name.

    enough-namestring returns an abbreviated namestring that is just sufficient to identify the file named by pathname when considered relative to the defaults. It is required that

     (merge-pathnames (enough-namestring pathname defaults) defaults) 
     (merge-pathnames (parse-namestring pathname nil defaults) defaults)

    in all cases, and the result of enough-namestring is the shortest reasonable string that will satisfy this criterion.

    It is not necessarily possible to construct a valid namestring by concatenating some of the three shorter namestrings in some order.

     (namestring "getty") 
     (setq q (make-pathname :host "kathy" 
                               (pathname-directory *default-pathname-defaults*) 
                             :name "getty")) 
     #S(PATHNAME :HOST "kathy" :DEVICE NIL :DIRECTORY directory-name 
           :NAME "getty" :TYPE NIL :VERSION NIL) 
     (file-namestring q)  "getty" 
     (directory-namestring q)  directory-name 
     (host-namestring q)  "kathy"

     ;;;This is similar to the above example but uses two different hosts, 
     ;;;U: which is a Unix and V: which is a VMS.  Note the translation
