O.P.Pick — issue with multiple nested picks from a single object

[mesqueeb]

🐞 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!

Yes, it works in the playground. AutoPath cannot work on arrays like this, the inference won't work. Please, set a playground up and I'll look what I can do.

@mesqueeb I fixed the issue, sorry for moving this to discussions. I re-implemented to whole O.P family. Thanks for pointing this issue out. Let me know it it's all good! I added your use-case to the tests, I'm gonna do this for all user posted code from now on.

[mesqueeb]

Thank you so much!

Hey @mesqueeb, is your pick function return type right ?
I can only get Union of objects. And with Union.Merge I get an object but nested objects of this object are still Unions :/

I think it's best you open a new ticket or discussion, and show your exact input, the current behavior and your expected behavior. : )
