Hi everyone! For learning purpose I'm porting some python examples to nim that
use the library blt, so far I got this:

The example is working except for the read_str function: when I finished
inserting the string, it prints always just the first character of the string.
I suppose the error is in this line:
discard terminal_printf(6,5, "$1", text)
but it seems legit to me. Anyone can help me? What's wrong?
Thanks!
