map over directory

Is there a function that would let me map over files in a directory?

	Thanks, Joel

Re: map over directory

DIRECTORY will return a list of the files in a directory that match a particular path:

(let* ((wild (make-pathname :name :wild :type "txt" :defaults #P"/Users/temerson/"))
(files (directory wild :directories nil)))
(dolist (f files)
(format t "~a~%" f)))

Hey Joel,

What about using this:

(mapcar #'namestring (directory "/"))

DIRECTORY returns a list of files in the specified pathname.
You can use MAPC instead of MAPCAR if you don't care about the result.



Best,
