Interesting question! Seems short answer is no, if you check out the help: DIRECTORY is the name of a directory, a string. But that of course doesn't mean you cannot have what you want. There should be many ways to do this. Perhaps even a standard one? The principle should be easy: 1. Apply the regexp on the set of possible directories, to get a list of matches. 2. Feed those one-by-one to the function. Now, step one is the tricky part. I would use the shell and ls. Like this: (let*((dirs-str (with-temp-buffer (call-process-shell-command "ls -d testdir/*/" ; shell regexp here nil ; no INFILE t) ; BUFFER (t -> current buffer = the temp one) (buffer-substring (point-min) (point-max)) )) (dirs (split-string dirs-str)) ) (dolist (dir dirs) (dir-locals-set-directory-class dir 'class-one) )) -- underground experts united
