🐞 Bug Report

Describe the bug

For this signature:

function pick<T extends Record<string, any>, K extends string> (obj: T, keys: F.AutoPath<T, K>[]): O.P.Pick<T, S.Split<K, '.'>>

this works:

however, adding a second key breaks the nested pick:

Reproduce the bug

// REPL or a link to your repository if applicable.
// A *self-contained* demonstration of the problem.

Is it possible to use TS Toolbelt in the typescript TS Playground? If so it's easy for me to replicate this.
Otherwise I can set up a branch on my package if you like.

Possible Solution

I'm not sure!

It happens that I forgot to distribute O.P utilities. I took the day to rewrite all of them. Nous you can do:

import {F, O, S} from 'ts-toolbelt'

declare function pick<T extends Record<string, any>, K extends string>(
    obj: T,
    keys: F.AutoPath<T, K>[]
): O.P.Pick<T, S.Split<K, '.'>>

type O = {
    a: {
        b: O
        c: 1
    }
}
const a = pick({} as O, ['a', 'a.b', 'a.b.a.c'])
