[@TminusDoom]

@@personal-stream-studio Yeah, you're right that they don't end up being simple and straightforward. I guess what I meant was, I don't believe anyone sets out making a new language without that being the intention. The only reason I see to make a new language is that someone thinks they can do something more simple or straightforward than one of the other 100 billion languages.

[@C4CH3S]

@@TminusDoomLook at go. still at 25 keywords, everything slightly complicated is in the stdlib, and some edge cases are made by the go team but not even in the stdlib (like the text or cases package) writing Go feels like i'm forced to do it the idiomatic way by how constrained it is, and that's good. it's been more than a decade and the language is about as simple as when it came out, with exception of generics maybe. compare that to Rust, which has an insane amount of features every update. I doubt their original idea was to be like Go simplicity wise. stuff like java which has about 10 ways of making an array and 5 ways of concatenating two strings together, if they had the Go philosophy like gleam also has, you wouldn't have those things. there is a method for literally anything you can think about on every type. gleam aims to be like Go, and if they do it like Go did in the last decade, I believe they can achieve their goal. for example, gleam doesn't even have a for loop, looping is strictly done with recursion.

[@angeloceccato]

Zig is a super language, but lsp is not a primary focus for them

[@FlanPoirot]

not a primary focus **at the moment**. they've made it clear that they will only work on those things after the language itself is further along, anyone that has hung around enough on the zig discourse channels knows that zls will eventually die as zig will have it's own autocompletion server in the compiler itself (they won't be using the LSP as their protocol)

[@PRIMARYATIAS]

Their main Lsp contributor died some time ago. 😢, probably because of that.

[@egorsozonov7425]

No, Zig is shit because no concept of trait/interface

[@FlanPoirot]

@@egorsozonov7425 that's the dumbest shit I've heard interfaces are nice but they're not a complete requirement, Zig is a C replacement which is a language that doesn't have those either, you just get data do soemthing and maybe return data. it's a different style of programming. if you were to give an argument for why zig sucks I'd think it would be more valid if you spoke about comptime's complexity and how it makes making good tooling harder. also there's a lot of inconsistency in the stdlib and the conventions used in the language rn. also the language is not even 1.0, it could completely change under ur feet, so unless you're very much into it and willing to contribute I'd advise u to keep out for now

[@RandomGeometryDashStuff]

12:18 isn't that what `static` keyword is for (properties on functions)?

[@nyahhbinghi]

Just like TS -> JS, I believe the incremental compiler for Gleam will be super fast

[@MadaraUchihaSecondRikudo]

Re: 16:00 - This is what the `static` keyword is sugar for. A property on the constructor function.

[@godbleak]

The caveat is that you then have to use the `new` keyword to access the non-static methods. I created a WooCommerce API client that had an interface like this: interface Products extends Methods { (id: number): { Variations: Variations } Attributes: ProductAttributes } interface ProductAttributes extends Methods { (id: number): { Terms: Terms } } /* Terms & Variations look much like the above */ interface Methods { retrieve: (id: I) => Promise /* other methods */ delete: (id: I) => Promise } This would mean that I can make a DELETE request to the `/products/1` endpoint like this: `await Products.delete(1)` make a GET request to `/products/2/variations/3` with `await Products(2).Variations.retrieve(3)` and make another GET request to `/products/attributes/4/terms/5` with `await Products.Attributes(4).Terms.retrieve(5)` To use static methods, that last one would look like `await (new Products.Attributes(4)).Terms.retrieve(5)` which just feels weird. (I suppose one could argue that the pattern I created does too, but 🤷)

[@sadaros95]

For that last part, information should be free, education deserves compensation

[@Lemmy4555]

I'm not a fun of currying because it adds a significant amount of "distance" from the caller to the "actual logic". A syntax like retry(3, fn) is much better, and if you want multiple functions to retry the same amount of times, just use a variable: retry3 = retry(3) res = retry3(fn) vs let times = 3; res = retry(times, fn)

[@chawakornchaichanawirote1196]

Haven't watched the vid yet. My ick with Gleam is division by 0 returns 0, because 'no runtime exceptions' for operations, except assert.

[@draakisback]

I played around with gleam a bunch, it's quite good. It's still missing a few things that stop me from moving from elixir to it. I would love to see OTP as a part of the core language given that it's a part of the core in the erlang virtual machine, I also think the import system is slightly clunky, I wish they had some kind of import that wasn't just aliasing. That being said, it has all the great features of elixir and erlang with static analysis. I am curious to see what the elixir type system will look like when they eventually release that, but gleam does fill a niche in the beam languages. I would also be curious to see how gleam handles native interface functions and interop in general.

[@dandogamer]

I've used gleam for the past 3 days and can confirm it's very easy to learn (even without knowing any preexisting functional languages)

[@RandomGeometryDashStuff]

11:36 I think javascript is less hard to read than c++ because there is less syntax (you know `array._isDefault = true` is assignment, now you only need to figure out how assignment to arrays works) and the many ways to solve problem use similar syntax features (I mean things like, addition, subtraction, multiplication, bitwise or, function declaration, class declaration, function literal…) but combine them differently

[@TJackson736]

4:18 That doesn't look like the assignment variable but the stream operator in C++. Notice how it can be reversed to stream out the response or an error.

I got really excited seeing this but then instantly realized that it will take years for this language to get any level of relevance to the point of doing it full time, if it even survives.

Gleam looks so cool! I went through the language tour and it really has the best parts of all language paradigms I used so far! And when they say "only one way to do things", they mean it! There's no for loops, only recursion (with tail optimization, of course), and all the typical functional list operations are built on top of that. There's no async/await or coroutines, there's just functions with callbacks, and the use keyword is syntactic sugar to make that easier to read and write. And there's no mutability in the language either, you use the erlang OTP with actors, so you have an in-memory key-value store for mutable state. This is how it always should've been.
