There has been some discuttion on the mailing list on how to make
bidirectional communication between clisp and other programs using Unix.
below is one solutoin provided by Mr. Haible.
>> (shell "mkfifo /tmp/wish-in")
>> (shell "mkfifo /tmp/wish-out")
>> (setq *lisp-to-wish-stream*
>> (make-two-way-stream (open "/tmp/wish-out" :direction :input)
>> (open "/tmp/wish-in" :direction :output)
>> ) )
>> (shell "wish < /tmp/wish-in > /tmp/wish-out")
>> (delete-file "/tmp/wish-in")
>> (delete-file "/tmp/wish-out")
As for my check, it doesn't work as they are seen above.
when (open pipename-out :direction :input) is entered, prompt never comes.
But (open pipename-in :direction :output) is entered, I can get #<FILE-HANDLE-STREAM #"out">.
I think only it can work in case of `:direction :io '. And I tried:
>> (shell "command < pipename-in > pipename-out") ,
but I couln't succeed. Has Mr. Hoefling already succeeded to connect
Any suggestion and information are welcome.
