[slime-devel] SB-EXT:RUN-PROGRAM and *STANDARD-OUTPUT* interaction in REPL

[Michael Weber]

[Apologies, if this hit the list twice.]

There seems to be some SLIME interaction between SBCL's
SB-EXT:RUN-PROGRAM and *STANDARD-OUTPUT*.  Consider this:

(defun test (stream)
  (let* ((p (sb-ext:run-program "tr" '("a-z" "n-za-m") 
				:input :stream
				:output stream
				:search t
				:wait nil))
	 (in (sb-ext:process-input p)))
    (format in "test~%")
    (sb-ext:process-close p)
    (sb-ext:process-wait p)))

Executing (TEST T) causes the output go to emacs' *inferior-lisp*
buffer, with (TEST *STANDARD-OUTPUT*) it goes to SLIME's REPL buffer,
although they should behave the same, AFAICT.

GNU Emacs 21.3.50.1
SLIME CVS-2004/08/13
SBCL 0.8.13


(I understand that this could just as well be an SBCL issue.)

Now, why this function hangs after executing is another thing which I
haven't figured out yet, but this is likely due to wrong use...


Cheers,
