How to: Flag whose presence disables validation (like --help)

[jasonkuhrt]

Hey, I'm trying to add a flag that behaves like --help in regards to how its presence disables validation of input.

How can this be achieved?

Note:

I am aware of preparse hook but in my case also need access to the command class to read some static properties.

I am trying the prerun hook but it gets undefined for Command at runtime. This seems incorrect given the TypeScript type does not declare the property as being optional.

import {Hook} from '@oclif/core'

const hook: Hook<'prerun'> = async function (opts) {
  console.log(opts.Command) // undefined
}

export default hook

We can override command init method. We already were, and were running parse there, but I didn't know that until now. Not sure if init by default does a parse too, or that's just because of our logic. Anyways, either way, init method overriding is the solution in my case.
