We discussed this briefly in a commit in dev-time-cli.

At the moment, when an error occurs and it is not handled by the developer, the entire error stack is shown.

devTime(cli.input[0], cli.flags).then(result => {
    console.log(time);
});

$ dev-time 0

This was before I disabled argument type parsing

When an error occurs, you got that "ugly" error string representation with the entire stacktrace. While this is very usefully, especially for debugging and reporting issues, it's not that user friendly.

proposal

Show a nice and clean error message. Something like pageres (but instead logSymbols.error).

If you want the entire stack trace, use the --verbose (or -v) flag.

Feedback and opinions more then welcome.
