Cleaning up when the app exits

[jcw]

Hello - I'm having a hard time figuring out how to cleanly restore the tty state to cooked mode when my application exits. I can use a defer.Close() in the goroutine where rl.ReadLine() is running, but the problem is that sometimes my application must quit programmatically (or panics). In these cases, the program exists and leaves the terminal in a very confusing raw/noecho mode.

The only workaround I can think of is to open a pipe to a child process, which then waits for its input to close before it runs stty sane (but this won't be portable to Windows, as far as I know). And it feels like a hack...

Is there a standard idiom for this? Or some example code, perhaps?

hi, it seems there has no ways to restore the tty state if it's exit unexpected.
And I can't see any terminal applications support this, even vim if I send kill -9 to it.
So, the only way is you keeping defer recover() it your every goroutines, make sure it exit properly.
