Disable prompt() globally

[jacobk]

Hello!

In line with https://clig.dev/#interactivity

If --no-input is passed, don’t prompt or do anything interactive. This allows users an explicit way to disable all prompts in commands. If the command requires input, fail and tell the user how to pass the information as a flag.

It would be great to have the ability to disable all prompt() and have them fall back to being normal options. Including handling of required() as needed.

Maybe this is already possible?

This isn't built in, but you could implement it yourself:

val noInput by option().flag()
val foo by option().transformAll {
    when {
        noInput -> "foo default" // or `throw MissingOption(this)` if it's required
        else -> terminal.prompt("Enter foo")
    }
}

Cool resource, btw! I sent a PR to add Clikt: https://github.com/cli-guidelines/cli-guidelines/pull/128

Thanks! Didn't know about transformAll.
