Skip interactive survey if devbox is not executed in a terminal

[LucilleH]

Summary

Skip interactive survey if devbox is not executed in a terminal. When devbox init or devbox generate direnv is called in a dockerfile for example, we do not want to prompt for user input.

I tried echo 'y' | devbox generate direnv or yes | devbox generate direnv or devbox generate direnv <<< "y". None of them worked.

Bug in the survey package: AlecAivazis/survey#394

How was it tested?

devbox run build
./dist/devbox init (interactive mode)

docker build -t devbox-cli .
docker run --entrypoint=/bin/sh -ti devbox-cli (non interactive mode)

Thanks for catching this

Could we make the result a bool outside of the if so we only need to do isatty once? Something like:

enableDirEnv := true
if isatty.IsTerminal(os.Stdin.Fd()) {
	// ...
	enableDirEnv := strings.ToLower(result) == "y"
}

if enableDirEnv {
	// ...
}
