Brendan MolloyI could really use some help with macOS UI work for this Mastodon client I'm working on. I'm struggling ridiculously with the core concept of NSTableView cell resizing.
Please boost.
charlag test account@piecritic hey, I'm an ex-iOS dev but I may help
@charlag every part of that toot is perfect.
@piecritic my journey was Android -> iOS (Swift!) -> (for the short time) Android -> iOS and Android (another guy leaves) and now I'm going to do Android only in another place
@charlag my company does Kotlin on Android to make it not totally suck. :)
@piecritic yeah, I brought Kotlin here too and it rocks. I miss some protocol stuff from Swift and that optional types are not real but apart from that it rocks, so many good design decisions
@charlag don't buy into that lie. Kotlin nullable types are real in Kotlin, as much as Swift nullable types are real in Swift.
Objective C can break those constraints just as well as Java can in Kotlin.
@piecritic I didn't mean that you can break it. Ofc you can. I meant that there's actually no optional types at runtime and you cannot make optional type from non-optional by hand
@charlag you've broken me. What do you mean by "cannot make optional type from non-optional by hand" at runtime?
@piecritic sorry, I probably hurry too much and cannot explain stuff properly.
suppose you have
let x = "Masto!"
How do you make a String? from x?
In Swift, you can
Optional(x)
in Kotlin, you cannot, there's no
enum Optional<T> { ... }
suppose you have
let x = "Masto!"

In Swift, you can
Optional(x)
in Kotlin, you cannot, there's no
enum Optional<T> { ... }
@charlag I thought that might be what you are saying, but I can't think of the use case.
If you really need that you can just do this:
fun String.optional(): String? {
return this
}
@piecritic there was one case when I wanted to use Rx like that
someNetworkRequest()
.map { Optional(t) }
.onErrorJustReturn(nil)
.filter { it != nil }
but I had to go with something like
.onErrorResumeNext(Observable.empty())
@charlag why were you passing an optional out of a map? I usually use flatMap to get _rid_ of optionals in Rx.
In RxSwift, RxOptional's filterNil.
@charlag btw, I can keep an eye out for Kotlin opportunities for you if you like. Tell me which continent you exist within and I'll ping you. :D
@piecritic oh my, that sounds awesome. I live in St. Petersburg, Russia but I would love to go remote (our move out of here)
@charlag ha, my first iOS contractor was from Ukraine and is now in the UK (which I made terrible ISO puns about).
@piecritic haha, sounds fun :D
@charlag when hiring Kotlin devs, we could only find people in Russia, Ukraine or Vietnam. Nowhere else!
@piecritic there's a reason for that I guess... https://mastodon.social/media/EtPtlR_pbKtE-XsX5Xs
@piecritic yeah, yeah, I know :D No one calls it by island name here, tho, but by city name, Kronshtadt.
And lighthouse on the kotlinlang.org is from there ofc
And lighthouse on the kotlinlang.org is from there ofc
@charlag you should create a kapt implementation of an optional enum that overrides all instances of Type? in a codebase and call it Kronshtadt just to spite everyone.
@piecritic totally! 😂
@charlag how often do the apps you work on rely on HTTP APIs for a majority of functionality?
@piecritic oh almost always I guess? I worked with awful API here...
@charlag right, so I use OpenAPI for literally everything now, and I have a Kotlin output.
You might want to play with it.
tl;dr you define a REST API in a YAML file, run it through a script, and get a Retrofit/OkHttp typesafe API + models out of it. xD
https://github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md
... and I haven't published the generator to github yet and only just realised omg.
@piecritic that's pretty cool, thanks for sharing!
@charlag yeah! It saved me about 1 month of real work time, and took about 1 week of real work to implement!
@piecritic automation rocks!
@charlag lol 33% of my iOS codebase is generated. Ever done localisation on iOS? ... yeah.
So I went around and it's awesome.
@charlag tl;dr my localisation library/generator can support Sami languages even if iOS doesn't. ;)
@piecritic !!
sorry, I think I have to work, was nice to talk
sorry, I think I have to work, was nice to talk
@charlag haha fucking timezones xD enjoy your day.
@charlag the best part is you aren't shitting a brick about accidentally implementing the API slightly wrong, because if it broke, the template is broken, or the generator is broken _on every platform at the same time_, so the bug is found really fast.
@charlag so I have one input, that can output a Swift, Kotlin and JS API. I generate my server's test API from the same specification that i use for mapping my routes to functions on Node.js... so many layers of self-testing.
@charlag but yeah, I didn't really think about the lack of a real Option type (like what Rust and Swift have) until you just said it.
