Hello,
is there any way to detect keyboard input using Nim? Something like this:
echo "What do you want to do?"
echo "1) Do something"
echo "2) Exit"
echo "Press '1' or '2' on your keyboard"
echo "What do you want to do?"
echo "1) Do something"
echo "2) Exit"
var choice = readLine(stdin)
case choice:
of "1":
echo "Chosen 1"
of "2":
echo "Chosen 2"
I would like to automatically detect "1" or "2" on your keyboard. Thanks for help!
I believe the Unix & similar way to do this is "CBREAK mode" on the terminal/tty device, but under Windows there is a totally different mechanism. I do not believe the Nim stdlib abstracts over these possibilities.
So, sorry to answer your question with a question, but I believe the answer to your question depends on if you are you willing to have this work on a subset of operating systems, and if so which subset?
@Stefan_Salewski is right - terminal.getch does abstract over OSes after all, though only (Windows & posix it looks like). So this code should work:
import terminal
echo """What do you want to do?
1) Do something
2) Exit"""
case getch():
of '1': echo "Chosen 1"
of '2': echo "Chosen 2"
else: echo "invalid choice; bye"; quit(1)
