Clear terminal / console in Crystal (CLI)

Question

How does one clear the console like with console.clear() in Node, but on Crystal.

I have searched around for a while but there seems to be no solution.

Answer 1

There is no fully standardized and ubiquitous way to clear a terminal. Most terminals recognize a special character sequence, though.

The string that has worked very reliably (and has been in my Bash aliases) is \33c\e[3J:

print "\33c\e[3J"
