Description

Hi!

Please try the attached program.

Expected result:

  • After you hit some key, the program should quit and the "Hit any key" message should still be visible on screen

Current result:

  • When the program exits, the screen contents is restored to what it was before the program was started

Note:

  • If you kill -9 the program, it exits without restoring the screen contents just like I want, but then it exits with a non-zero return code.

The use case is that I want my pager implementation to be able to exit without restoring screen contents when pressing C:

I currently use the kill -9 workaround, but would like to be able to do without it.

Regards /Johan

You can use Process.exit! in such a situation.

Try appending "Process.exit!(0)" at the end of your code.
