After letting it run for about 5s before hitting escape, on separate terminal windows:

 

=={{header|PicoLisp}}==

 

(zero *Cnt) # Initialize byte counter

 

(push '*Bye '(call 'rm "in" "out")) # Remove pipes upon exit

Test:

<pre>$ line <out

 

=={{header|Racket}}==

 

(define-values (in out) (make-pipe))

 

(thread-wait t1)

 

=={{header|Raku}}==

{{incorrect|Raku| Blocks on the read pipe and not able to empty/update the write pipe according to the task requirement }}

Couldn't figure out how to get around the IO blockages as per the talk page so any help would be appreciated, thanks in advance.

{{works with|Unix}}

 

 

# Ruby has no direct access to mkfifo(2). We use a shell script.

end

end

 

Example run:

 

=={{header|Tcl}}==

exec sh -c {test -p in || mkfifo in || exit 1;test -p out || exec mkfifo out}

 

 

# Run the event loop until done

 

=={{header|Wren}}==

 

This works fine on Ubuntu 20.04 and should work on other Linux distros though I can't vouch for anything else.

 

var InputFifo = "in"

 

Fifo.make(InputFifo, 438)

We now embed this script in the following C program, build and run from one terminal.

 

#include <stdio.h>

free(script);

return 0;

zkl doesn't open pipes but it knows about them (on Unix anyway as they are just a file). So, outside of the program, create two named pipes and read/write to them inside the program.

{{trans|C}}

fcn writeLoop(pipe){ // a thread

out:=File("out","w");

}.launch(pipe);
