exact length "string = 2"

Can we do something like stateCode: 'string.alpha = 2' ? stateCode: type.string.exactlyLength(2), works but curious if the = works

import { type } from 'arktype';

const x = type({
  stateCode: '1 < string.alpha < 3',
});

const out = x({ stateCode: 'Error' });

if (out instanceof type.errors) {
  console.error(out.summary);
}
//  error is: stateCode must be exactly length 2 (was 5)

import { type } from 'arktype';

const x = type({
  stateCode: '1 < string.alpha < 3',
});

const out = x({ stateCode: 'Error' });

if (out instanceof type.errors) {
  console.error(out.summary);
}
//  error is: stateCode must be exactly length 2 (was 5)

maybe something like this I think using = is assigning default value there

= means default So here you need 2<=string.alpha<=2

I see. Maybe a “===“ alias would make sense here

Dimava•4d ago

Maybe it's there and we've just not tried it lol So It was there all the time

Wait you mean ===?

import { type } from 'arktype'

type("string == 123")

import { type } from 'arktype'

type("string == 123")

no ==
