I test, works VERY good. :)
Thanks. For now, I will use only the charterm-screen-size function, because
until I use more the charterm-insert-line
is simpler to cut the output to serve only some number of lines. I will use
charterm-insert-line in the future.

If you're on a Unix, like GNU/Linux or a BSD, you could use the

(require charterm)
(with-charterm

(charterm-clear-screen)
(charterm-display "Width: " w " Height: " h " ")
(charterm-cursor 1 2)))

Well, another possibility is : instead of call main.rkt, call start.sh
where start.sh can get the number of lines just using LINES environment
variable and use that as argument.
Something like :
#!/bin/sh
#start.sh
racket main.rkt $LINES
#end of start.sh
What do you think? Is ugly? There's a
Well, I know that the game will run only on Gnu/Linux systems. A
alternative that I see is using ffi to provide 1 function that returns this
number but if exists some racket-only solution I think is better, right?

Thanks Ben.
The problem is that this functions can give me the number of line that live
my next read, but cannot tell me "Well, this port is a terminal and have 80
lines of height".
With the height information I can control the display but without that, and
using just port-count-lines! and port-n
Maybe use `port-count-lines!` and `port-next-location` ?

Hi everyone. I am coding a console-based game in racket to teach shell to
freshman on university. In some point, I need to print a message that can
