Wild pathnames

[Faré]

My apologies: blindly copying and pasting from Google+ was a bad idea.

Here is the command I ran, where cl is the latest cl-launch 4:

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

And the summarized results are:

Escape properly:
("sbcl" (#P"/tmp/x/\\*") "*")
("ccl" (#P"/tmp/x/\\*") "\\*")
("cmucl" (#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
