Hi, I'd like to be able to set the location of the *.fasl files that are ending up in ~/.slime/fasl/..., preferably from my .emacs. I tried setting slime-compile-file-options in my .emacs file as follows (eval-after-load "slime" '(progn (setq slime-compile-file-options (append '(:fasl-directory "/tmp/") slime-compile-file-options)) ...)) but that didn't seem to do it. Then I tried to put the following in my ~/.swank.lisp file (setf swank:*fasl-pathname-function* (lambda (input-file options) (declare (ignore options)) (let* ((str "/tmp/") (dir (filename-to-pathname str))) (assert (char= (aref str (1- (length str))) #\/)) (compile-file-pathname input-file :output-file dir)))) but that didn't seem to do it. Many thanks for any suggestions! Cheers, David
