I like rust’s arrow syntax. So easy to see what is what . Ts have colons everywhere, such a pain to know if its a type, a return type or another thing

[@sk-sm9sh]

Return type IS a type. What the heck you're talking about? But I hear you it's confusing because on object notation column is value assignment operator yet in ingerface/type its type declaration.

[@stevenhe3462]

Agreed. In Kotlin and Python, I hunt down where the return types are. A big arrow helps a lot in that sense.

@live is a broken feature, very raw and as a borrow checker it probably wouldn't scale. D also has memory safe and pure tags out of the box, these are pretty cool. Not this but meta programming in D is probably the best out there in terms of easiness to read and write.

Vala, Genie, and others (original c++) have compiled to C for decades. It's low level enough to be similar to compiling to asm. It's really not _that_ different than LLVM, atleast not fundamentally.

[@harrytsang1501]

Compiling to C also has the added benefit of the half-century worth of optimization out of the box. Also just like LLVM but at the same time C has a much more well known interface than LLVM.

[@guywithknife]

Chicken scheme, ATS and many others also do this

[@Hazanko83]

Copy as default makes more sense if you're not constantly passing objects around, and only passing basic types like integers/floats/etc. In my game I'm working on in C++, i'd guess over half of all my functions operate on basic types, and the remainder is passing around pointers(which technically exists ITSELF as a variable and gets copied). The cpu has no real problem just creating basic types like integers and shifting them around, while copying the address of a pointer then possibly needing to do a memory lookup is much more expensive - especially if the cpu was already working on the values being passed. In something like javascript where ''everything is an object'', I'd guess basic types being copied might be more expensive(I'm not sure)?

[@9SMTM6]

Somebody mentioned Vale in your chat. That seems like a far more interesting language to me if I were to adopt a newish language. (do note, Vale, not Vala)

[@toup0]

There is no definition for arrays that says something has to be immutable and on the stack to be a technical array. Well in rust we call it array and vector, there this distinction is clearly made. But it can be a dynamic, heap allocated list and still called array. Like it is commonly done in many langs. For fixed sized arrays in v that are put on the stack, the syntax is e.g., `mut fnums := [3]int{}`.

[@brotheradamfromups]

Or the short syntax is to use ! at the end of your expression. This also allocates to the stack arr := [1, 2, 3]!

[@nabilabdel-hafeez3916]

Fyi: the name: Type annotation comes from Scala. Inventor Martin Odersky chose it, because the colon is a mathematical notation for element of a set (usually you learn in school the symbol that look like similar to €). So you could read a: Int as a is an element of the set of integers.

[@RuslanKovtun]

8:00 - as a vim use you should know how awesome it is to have some separator before type to navigate quickly.

[@empresagabriel]

Thanks for the video, Prime!

[@andrewgjkgjk]

I think the whole thing about references was maybe a nod to performance considerations. I think perhaps he was conveying that if you have some big struct and you're passing it into a function that doesn't mutate it, the compiler passes a reference instead. This way, the function operates as if a tedious time consuming copy had been made to pass it by value, but without that overhead. I mean, the style of the video leaves open the possibility that he was describing some cool "optimization" vs something the user would ever really perceive semantically from the feature.

how? its a v program that translated doom C to V. thats pretty impressive

[@icoudntfindaname]

​​@@asad-ullahkhan2368 and then THAT V code is again compiled to a similar(less efficient even) C code C is so "simple" that it could possibly be transpiled to many langs... You just lose efficiency... But V is compiled back down so that doesn't matter.... All you need are pointers, functions, integer types etc... Mostly just basic stuff

[@asad-ullahkhan2368]

@@icoudntfindaname the impressive part is translating the C code to V, not the transpiler. It shows you can incrementally convert a codebase to V (or all at once even). Besides, the V compiler also has an LLVM emitter, which will eventually be able to run doom as well (if not already capable of that)

[@asandax6]

V is still pretty much in alpha stage. They transpile to C because they haven't implemented a direct compiler and for some reason the V developer hates LLVM and doesn't want to use it for compiling.

[@Pece0]

@@icoudntfindaname You missed the point of the past 30 years (at least) of language design then. Most languages abstract away from the simplicity to ensure security. Yes C is a simple low-level language, this is what makes it *difficult* to translate it into a high-level language. Precisely because that's the point of high-level languages! If we could do the same prone-to-errors manipulations in Haskell as in C, nobody would program in Haskell, everybody would program in C directly and not compromise on efficiency. (I took Haskell as an example, this would work for basically any language which is not a dictionary for C). So the fact that you can translate a fairly large project like Doom automatically from C and then compile it by any means (including transpiling back to C on the way) and still have something decently runnable is pretty impressive. That being said, I don't really see the big innovation that this V thing is supposed to be.

I'm primarily a Go dev. I also use some other languages at work but Go is my main one. V is definitely heavily inspired by Go.

It won't be a language I'd use for actual projects any time soon though. But it's promising .

[@stephanpio]

I like your content, but it seems like your community is sounding more like haters day by day. In my view, they are just looking for validation by the streamer. I bet less than 10% have their own true opinions nowadays, and instead just look to have an opinion Prime would agree with. Most tech youtubers who stream seem to have echo chambers behind them, which I guess is good for their community, but perhaps not the best for meaningful discussion. I'd like to see content with people who have contrarian viewpoints but in Prime's content I just see echoes 99% of the time. I am just one guy on the internet, and probably sound like a hater as well, but just as Prime criticizes or has contrarian viewpoints to the things he reacts to, it would be great to hear the counters of his points as well.

[@xplinux22]

Yep, Rust is entirely null-safe by default (see Option). Note that within the scope of an *unsafe {}* block, you may work with raw nullable pointers, should you need to do so for advanced purposes. For instance: implementing self-referential or cyclical data structures that the borrow checker currently rejects, calling C functions via FFI, etc.

[@toddmartin7030]

I agree with you on the properties and interfaces. Taking a language like C# or Java, if you can put properties in the interface, to me it really blurs the lines between what a class is and what an interface is. Interface should only describe behavior and be decoupled from internal data. Once an interface has internal data, it pretty much is a class.

[@asandax6]

V doesn't have classes so that's why you have properties on interfaces.

[@toddmartin7030]

@@asandax6 Structs with methods are essentially roughly around the same thing without inheritance. A class at a high level is essentially data coupled with behavior. Taking this sample from Vlang struct User { age int } fn (u User) can_register() bool { return u.age > 16 } This is essentially a class, just without polymorphism and a different syntax. Why Do I need a property on an interface when I can just implement getters and setters or make a public property on the struct itself? Under the hood the above example and the following are not really that different. class User { int age; public bool can_register() { return this.age > 16; } } In most cases, these are not that functionally different from one another.

[@sacredgeometry]

How does it blur the line? For most of its existence it was a specification. These days though they really have gone full retard with interfaces in C#. Properties are syntactic sugar around getters/ setters so methods backed by a field. Why wouldnt they belong on an interface?

[@toddmartin7030]

@@sacredgeometry Interfaces are more about guaranteeing same behavior without concrete implementators having to have the same data. If you want to guarantee two classes have the same data and behavior, well, that is what super and subclasses are for. Properties in an interface seems like it is trying to not only guarantee behavior, but also guarantee shared data. Getters and setters are not really behavior in my opinion since your directly working internal data to a struct or class. Or it opens the door to it.

[@sacredgeometry]

​@@toddmartin7030 I am not sure I agree with that at all. It's not about guaranteeing they have the same data or behaviour. Why use an interface if you wanted they had the same of either of those things. It's about making sure they have the same interface. "Getters and setters are not really behavior" Of course they are they are essentially no different to having two methods GetSomeState() and SetSomeState() That is behaviour. Some examples from C# IEnumerator has a Current, IList without a Count, IDictionary has a property to retrieve the Keys and another for Values. Its not exactly hard to imagine why you would want the interface to specify properties.

Like its crazy how when code compiles it works for so many cases the first time.

1. If you're finding lifetimes hard for some code, try throwing an Rc or using indexes instead. It's generally a hint that what you're doing isn't something "transient" which is really what lifetimes are for 2. Complex macros like serde use procedural macros, not macro_rules!. They're a bit more to set up, but then they are just Rust code running on compile on your source. Much simpler for fiddler cases. 3. impl Trait in return type just looks at the type returned from the function body and uses that (without exposing the type in the signature). impl Trait in parameter creates a hidden generic type parameter. They're both pretty simple transformations. Impl Trait in types is much harder, as it essentially means it has to look at the usages of that type and guess which specific type to use, which could need to look at the whole program, or mutually depend on other types stuff impl Trait, etc. And it won't even do what you want in that case, which is being able to return different types in different functions. Use a Box to use a trait polymorphically. The real problem with Rust is it makes things other languages don't let you do so easy, that you can get quite far without needing the slightly worse but more general thing. As an example, the equivalent of a C# List is basically Arc, and that's what you need if you want to use it like you do in C#, sharing it between threads and modifying it wherever. But if you just need it in one place, Vec is fine and way cheaper.

It's a Veasel !

Colon as function return type operator? Yep at first TS way looked like it's more consistent .. function xyz( n: number ): number ... but actually maybe it is not. First colon mean value type and second is return type. Function has no type, it is a function - it returns a value of some type so it's basically a different thing, just slightly but different. At first I too didn't like the -> thing in Rust but it make sense .. a little more than colon in TS. Also I liked no semicolon and no colon syntax in Go for some time. But nowadays the Go/V syntax seems to me like too much void, too much magic syntax, too much 'not obvious - convention based' syntax.

I look at this from consistency perspective. I prefer the TS design, where syntax for type annotation is always DEFINITION + COLON + TYPE

I don't really know what was so bad about return type first before function name. int foo() Vs fn foo() -> i32. I like a lot of the things that rust does but this just feels like extra boilerplate for no reason.

[@jsonkody]

int foo .. is somewhat elegant in a way, but also its kinda backwards. We are wired that we think of name first, then we want to know what it returns. This way you see from left to right what returns, than what is the name of something, maybe youll think about the name, then return back to start what it will return :) It's all wrong way .. but it's short.

@@georgehelyar Read Rob Pike's article on Go's syntax. I can't share a link since YT would delete my comment. But basically there's nothing wrong with your example, until you start making it more complicated - such as signatures of functions that return pointers and take pointers to functions that take and return pointers. The Go/Rust way would be easier to read and write.

I love C++ style lambda syntax. It will grow on you.
