Each vendor has his/her own mailing list or other contact point where to submit bug reports and other requests. It looks like most vendors are here though. mkdir -p /tmp/x ; touch "/tmp/x/" ; for i in sbcl ccl clisp cmucl ecl abcl scl allegro lispworks gcl xcl ; do echo $i ; cl -l $i -iw '(let ((x (directory "/tmp/x/"))) (list "'$i'" x (pathname-name (first x))))' ; done #cl Escape properly: ("sbcl" (#P"/tmp/x/\\") "") ("cmucl" (#P"/tmp/x/\\") "") ("ccl" (#P"/tmp/x/\\") "\\") ("lispworks" (#P"/tmp/x/\\") "\\") ("scl" (#P"file://localhost/tmp/x/") "") Read badly: ("clisp" (#P"/tmp/x/*") :WILD) ("ecl" (#P"/tmp/x/*") :WILD) ("allegro" (#P"/tmp/x/*") :WILD) ("xcl" (#P"/tmp/x/*") :WILD) Error out: abcl Fatal condition: Bad place for a wild pathname. gcl: Fatal condition: Condition in LET [or a callee]: INTERNAL-SIMPLE-FILE-ERROR: File error on "/tmp/x/": File "/tmp/x/" is wild Some of the results are obviously erroneous, but I don’t quite understand some of the others… (my POSIX-fu being very rusty). The script you posted is (reformatted) mkdir -p /tmp/x # Creates directory /tmp/x/ touch "/tmp/x/“ # What is the intended effect here? for i in sbcl ccl clisp cmucl ecl abcl scl allegro lispworks gcl xcl do echo $i cl -l $i -iw '(let ((x (directory "/tmp/x/"))) (list "'$i'" x (pathname-name (first x))))' done #cl If you execute the first two commands on a Mac the result is a just to create the /tmp/x/ directory. The call to DIRECTORY in CCL then returns: Welcome to Clozure Common Lisp Version 1.8-store-r15418 (DarwinX8664)! ? (directory "/tmp/x/") (#P"/private/tmp/x/“) ; Which may be correct by interpreting the CLHS. The call to DIRECTORY in LW returns CL-USER 1 > (directory "/tmp/x/") NIL ; Which may be not be appropriate... In SBCL you get This is SBCL 1.0.49, an implementation of ANSI Common Lisp.

In SBCL and CCL the PATHNAME-NAME returned is NIL. I would have expected no escaping and NIL as pathname names. Cheers -- Marco Antoniotti
