Zig for Impatient Devs

[@IsaacHarrisHolt]

ERRATA: 0:33 - I mentioned that Zig doesn't have nice stack traces. This isn't true! They're very good, and quite detailed. It also does have a package manager. See @mlugg5499's comment for more information :) (or see the package manager release notes: ziglang.org/download/0.11.0/release-notes.html#Package-Management) 1:18 - []const u8 is a SLICE of const bytes, not an array! Also, strings will COERCE to this type, but as @rexicon2269 correctly pointed out, Zig string literals are technically constant single item pointers to null terminated byte arrays (*const [N:0]u8), however, I left this out of the video as we didn't cover sentinel termination :) 1:30 - @as is not a cast! It's effectively an inline type assertion. It'll only work if the type can be safely (upwardly) cast (thanks again @rexicon2269) 3:02 - The output would be 1, 4, 16, 64, not 4, 16, 64, 256 (thanks @someoneunknown6894!) 4:15 - There are some `const`s missing from types (thanks @unperrier5998!) 4:27 - The first line should be `const x` (thanks @GhislainGt!) 4:43 - Same as 1:18 4:58 - Missing `u8` between `[_]` and `{0}` (thanks @unperrier5998!) 5:39 - Struct fields are assigned with `=` not `:` (thanks @unperrier5998!) 8:18 - The inline loop should print `false` twice at the end (thanks @jcsahnwaldt!)

[@raffimolero64]

Nice work. Good middle-ground between Fireship's " in 100 Seconds" and other more in-depth tutorial vids. 7:10 Rust's actual Option type declares `None` before `Some`, affecting the order of comparisons. This means the discriminant (tag) for None is 0, None < Some(0), and this behavior will be optimized out for Option. 9:16 As a newbie, I hadn't seen this syntax before. Looks like the while loop is taking an expression, which should only return true or false as per if/else, but the expression manages to return a value which is captured in the block. It looks more like some sort of Optional value matching, which wasn't explained earlier. I did a little bit of research and it looks like you can run an expression like if (?T) |t| { doSomething(t); } else { doSomethingElse(); } which appears to be special-cased for optional types and error unions. Maybe this errata comment could also be used with a "NOT COVERED:" section to dump a bunch of keywords that may be important to search, starting with the words you said at the end of the video. One thing you haven't mentioned, I think, is tests. Just put those words in there and go. The video is long enough, writing out whole examples in a comment would just be extra work that could go into making a part 2.

At 0:39 the PATH specified is also incorrect. It should be a path to where the binary resides, not a path to the binary itself. In fact, /usr/bin very well should already be in the PATH variable.

[@Maagiicc]

All of this looks pretty good, but I think I'll stick with C

[@pierreollivier1]

Zig is really my favorite language, as a C developer it really is everything I wish C was and more : - No more Macro cancer. - No more make/cmake/ninja cancer. - No more implicit integer promotion foot guns. - No more namespace conflict. - No more quirks. - No more checking for null everywhere. - No more void* and macros for generic. - Actually useful and usable standard library. - Seamless interop with C. - Lower level control than C with native support for SIMD primitive. - Errors as value. - Stricter type system. - Allocators are first class citizens - Very readable and explicit code, there is next to no hidden control flow everything you read is everything you get.

[@IsaacHarrisHolt]

This is exactly what Zig is trying to solve! It's still not my cup of tea personally - I like slightly higher level languages - but I'm not solving low level problems, so I don't need as much control as Zig provides. That said, I definitely want to experiment more with working on low level systems and such, and I think Zig is definitely a fun way to try and accomplish that.

[@pierreollivier1]

@@IsaacHarrisHolt That's understandable. If you wish to get the broader perspective on why Zig is so awesome, a quick experiment that I would recommend, would be to re implement something relatively trivial like hex dump. Try to do it in C, try do to it in your favorite language, then try to do it in Zig. This shouldn't take too long, (around 500 loc for a bare bone implementation). If you try hard to write good C code redoing everything in Zig will really give you valuable insights on why Zig is so great.

Zig big feature is seamless integration with C, not only using libraries in both directions with lon the fly bindings generation but zig even can compile C code or be used as build system (programmed in Zig !)....

[@IsaacHarrisHolt]

Cool! What would you say is your favourite Zig feature?

[@koool56]

⁠​⁠​⁠@@IsaacHarrisHoltWell, it’s three things I missed in C, hard to pick one. * optional value as 1st class language citizen (not unwieldy C++ implementation, null pointer or magic value) * being able to add methods to structures (C void pointer way loses type safety and syntax is nuts) * Errors as values, checking for null on top of checking some global error variable is hacky in both C and C++

[@IsaacHarrisHolt]

Very valid reasons! Let me know how you get on with Zig

[@mlugg5499]

At 0:33, you mention some missing features. Firstly, Zig does have a package manager - it's a quite recent creation and so somewhat immature, but it does exist, and is being used in the wild (the best example is probably the Mach project). Secondly, I'm not sure what you meant by "reasonable stack traces". I haven't heard of any major issues we currently have with stack traces - in general, stack traces are printed by the panic handler on any crash, and they're detailed & prettified. If you've encountered any specific issue with incomplete/incorrect stack traces, that's a bug, and possibly one we're not aware of, so please report it!

[@IsaacHarrisHolt]

Apologies for that! I couldn't find any information on the Zig package manager (I assume you mean Zon?) on the ziglang.org site, so I assumed it was potentially third-party, like nektro/zigmod. If you could just make sure I've got the right one, and provide some documentation, I'll include a link in the pinned ERRATA comment. I'll do the same re the stack traces. I don't know why, and I can't reproduce them, but I didn't have a great experience when I was researching for this video. Thanks for calling me out, though!

[@mlugg5499]

(I just wrote a detailed reply here and KZbin in its infinite wisdom deleted it when I tried to fix a typo. I'll rewrite it later on :p)

[@IsaacHarrisHolt]

Looking forward to it :)

[@mlugg5499]

@@IsaacHarrisHolt Sorry it took me so long to get around to this, I've been quite busy. Okay, so! ZON is not the name of the package manager, but rather a file format. It stands for Zig Object Notation - like JSON, we've basically taken Zig's construction syntax and turned it into a file format. ZON is used by the package manager, but it's a general-purpose file format. The package manager itself does not have a name - it's just a system integrated into the compiler. The way it works is that you create a file named `build.zig.zon`, which declares the name of this package, and all of its dependencies and their URLs (the package system is decentralized, unlike e.g. npm). These dependencies can then be referenced from your `build.zig`. The schema for this ZON file is detailed at github.com/ziglang/zig/blob/master/doc/build.zig.zon.md. Unfortunately documentation for the package manager itself is a little lacking at the minute - the best resource is probably the release notes for 0.11.0 (ziglang.org/download/0.11.0/release-notes.html#Package-Management), but keep in mind that might be a little outdated. You can see an example package at github.com/andrewrk/SDL, and an example usage of said package at github.com/andrewrk/sdl-zig-demo. I hope this helps!

[@IsaacHarrisHolt]

Very helpful, thank you! I'll add a link to this comment in the errata :)

[@blouse_man]

Zig feels like a mix, can u tell what the special reason for which zig is in the talks for sometime now??

[@IsaacHarrisHolt]

A lot of it is down to how low level you can get with it. It's as low level as C, but ultimately safer. Comptime is also very useful once you start getting into advanced stuff with it - much nicer than headers and macros.

[@pierreollivier1]

Zig is meant to replace C, If you know C well you can clearly see (no pun intended) that Zig was built off the frustrations of C. The problem with C is that it lacks type safety, and carries a lot of terrible decisions, namely, macros, preprocessor, nullability implicit conversion rules, forward declaration etc. You might think that alternatives already exist, like C++ or Rust, the problem with those languages is that they aren't "real" C replacement, Why ? Because they don't follow the same set of principles. Zig on the other hand really focus on simplicity and ease of use, especially if you are a C programmer all of the very "unsafe" things and all of the error prone stuff is replaced with more explicit or safe constructs and idioms. In Zig you can't cast variables as freely as you used to do in C, instead you have to use specific builtins to do so. You don't need to use macro magic or void* to get generics, instead you can use a safe alternative called comptime. You don't need to worry about the build system and portability and linking error, instead you can use Zig to build Zig. You don't have to migrate to a new testing framework, instead you can just rely on the Zig builtin testing framework, You don't need to use more macro magic from another language to generate bindings to interops with your old C you can just compile it with the Zig compiler, You also avoid namespace conflict out of the box, and so much more that I can't really name everything, the point is that I'm a C developer, and Zig literally is everything I wished C was.

[@joopie46614]

This looks a lot like rust in some cases, I also see a lot of rust developers alternating between rust and zig, it looks promising. As for things like panicking on integer overflow, how about dynamic integers? Does it have runtime checks for overflows? That sounds like a poor trade off between performance and safety.

[@mgord9518]

It has runtime checks in Debug and ReleaseSafe mode. For ReleaseSmall and ReleaseFast, integer overflows are UD

[@IsaacHarrisHolt]

Good to know, thanks!

[@dealloc]

i think the analogy most people make is Rust is "the new C++" and Zig is "the new C". Of course doesn't mean they're going to replace the languages; just that Rust is more implicit like C++ and Zig is more explicit like C. Of course it's not apples to apples, since C++ is (somewhat) extended C, not the same history with Zig and Rust. Interop between the two is a whole other rabbit hole :P

[@rexicon2269]

at 1:18 this is not a array of "const u8" :) it's actually a slice of "const u8". the difference being "[]const u8" and "[N]const u8", where N is a comptime known value. "this is a string" is of type "*const [N:0]u8" aka a pointer to a const 0 terminated array of u8. this then coerces into a []const u8 through the explicit type you give "const string: []const u8". same thing at 4:43 minor error, but they are distinctly different things. error 2: at 1:30 the @as is not a cast. it's a inline way of writing `const flt: f80". the actual cast here happens implicitly. the same thing would have worked if you had written "const flt: f80 = 5000.1". of course this can only happen if it's a safe cast such as casting upwards i.e u32 => u64. casting downwards would not work, and be an error, and would require i.e @intCast

[@IsaacHarrisHolt]

Have added to the pinned errata comment! Thanks for calling me out :)

[@j.r.8176]

Why do arrays store their length by default? isn't that memory wasted? Also what's a point of 'arbitrary bitwidth' variables? All modern CPUs have a minimum operation width of 8 bits. If you define two variables of type 'u3', it is smart enough to fit both into one byte? Or will it fit each into an individual byte? If it's the latter then what's the point?

[@IsaacHarrisHolt]

To answer your first question, yes, it's extra memory usage at the cost of safety. As for the arbitrary bitwidth ints, I'm not sure. I would Google it, if I were you.

[@LageAfonso]

I don't feel like Zig syntax is well structured enough, seems like a bunch of syntax sugar that someone just added to make things work. Maybe I'm just used to Rust typesystem.

[@IsaacHarrisHolt]

I do love the Rust typesystem. Zig is still technically pre-1.0 though, and I think there's a lot of room for it to grow and improve

[@shrin210]

​@@IsaacHarrisHolt There is no room to grow and improve syntax i guess

[@IsaacHarrisHolt]

Major versions could introduce breaking changes :)

[@pierreollivier1]

From the perspective of a rust developers maybe, but if you've been programming in C extensively, you might be able to see that basically all of the "syntactic sugar" is really just very common C idioms (who are very error prone, or unreadable) expressed in a shorter and or safer way. Because the target audience for zig is really just C developers who want to migrate/maintain their old code base with a more modern and safer language, with more control/freedom than what Rust offers (at the expense of memory safety), and without the ugliness of C++. Which makes a lot of sense, I also believe that they've said that the syntax might evolve once everything is ready for the 1.0 as they don't think syntax should be their primary concern.

[@IsaacHarrisHolt]

I disagree with the developers here somewhat. People these days are generally flocking to languages that feel good to write, and syntax is a big part of that. Zig is currently lauded because it's a vast improvement on C, but lots of things are a vast improvement on C, tbh. As soon as a 'Zig with nice syntax' comes along, Zig could be in trouble.

I really like Zig in concept, as a replacement for C it's definitely a stellar option with just straight upgrades everywhere! I've never really worked that low-level though, I don't deal well with the whole "manual memory management" thing, which is why I'll probably stick with Rust instead. What's really sad to me is how awesome the whole comptime and emergent type meta stuff is, and how that whole system is probably fundamentally incompatible with Rust's type system. If the Rust team ever finds a way to integrate all this comptime magic into their code naturally, it's really gonna pop off for me! (and yes I know macros exist, but they only operate on tokens and not actual types and structures. Again because Zig's model of building the types at comptime seems pretty much incompatible with Rust's type checker.)

[@IsaacHarrisHolt]

I like this take! Yeah, comptime is pretty much my favourite feature of Zig. Like you, I prefer Rust's memory management and I find the type system more robust.

What's init-exe?

[@IsaacHarrisHolt]

It's how you initialise a new Zig project. It's technically not needed, but it gives a nice structure etc. It's kinda like Cargo init, but more optional

[@EduardKaresli]

OK, we have C, C++ and Rust, why would one prefer Zig instead? What is Zig's best use-case scenario?

[@IsaacHarrisHolt]

Zig is supposed to be a replacement for C. It's not finished yet, so it doesn't cover quite as wide a surface area, but I can see Zig being used anywhere C might. A good example is Bun, the new JS runtime built as an alternative to Node.

[@IsaacHarrisHolt]

[@ΝικΝοκ]

@@IsaacHarrisHolt Seems pretty fast and nice. I saw a video of zig being the first in speed in some task. Faster than c and rust. That is amazing ! I hope it replaces c or at least be used as much as c. It feels like a new breath or smthing. I like c / c++ but i would totally love to use zig for a project in my university. The only drawback i see atm is that i feel i cant use it for something solid or long term (since i guess there would be some changes in the languages ). Mostly for some demo projects i guess. I hope it goes well

[@IsaacHarrisHolt]

There are some pretty big production projects happening in Zig right now - you can definitely use it long term! There's nothing saying you'll be forced to update versions.

[@KimberlyWilliamsch]

So it's literally modern c

[@IsaacHarrisHolt]

Pretty much! It's a vast improvement

[@f.artemenkov]

Why the modern language as Zig still need semicolons as end of the line?

[@IsaacHarrisHolt]

A lot of the time it can prevent undesired function calls, or situations where the compiler may get confused between attempting to call a function or some.other operation with parens

[@j.r.8176]

Removing semicolons is a step backwards, not forwards. Regard.

[@IsaacHarrisHolt]

My RSI disagrees

[@ThatBonsaipanda]

Whitespace is not a good character in source code (hidden). Imagine that the compiler sees the source code as one continuous line, not like how we view it on screen.

[@lmnts556]

Very well done, just not a fan of the zig syntax. I honestly prefer the c syntax over zig. Zig reminds me of java and I really hate java.

[@user-he4ef9br7z]

Really not a replacement for C though. The whole advantage of C is that it maps very well to assembly and how memory is represented. Zig seems to have too many abstractions, making it more high level. Anyways, looking forward to learning and implementing it.

[@IsaacHarrisHolt]

Fair take! I think Zig is supposed to give you as much low level control (which I think it does) while being safer than C. Glad you enjoyed the video though!

[@lockbert99]

I would say the majority of "modern languages" allow exceptions for errors. And they all have a string type. But with "try" and "catch" in the language it looks an awful lot like exception handling.

[@IsaacHarrisHolt]

I disagree. With exceptions it's difficult to predict where errors are going to come from. Error unions tell you in advance that a function could throw an error via their return type. Take JavaScript for example. `JSON.parse('not JSON')`, will error, but there's no warning in advance. Also, by returning the error rather than throwing it, you know the code won't stop unless you explicitly tell it to stop.

[@lockbert99]

@@IsaacHarrisHolt I think input data is ideally verified with a predicate function. If it is too much to do both (verify and process) there should be an indication that a function returns an invalid input error. I wouldn't do that with an exception in C++/Java etc. since it is a known possibility that the data is malformed and the function should return success/failure. If the Zig code is forcing error handling on a function with a known error possibility that's a good feature since programmers can code like, for example, fopen will never return NULL. I would save exceptions for errors that cannot be anticipated and which don't have a path forward other than program termination and find out what went wrong.

[@IsaacHarrisHolt]

Fair take! This is what languages like Go and Rust do. Errors are values, so you're forced to handle them when they arise, but you can also panic to halt termination

[@CodingResoures]

zig vs rust

[@IsaacHarrisHolt]

Personally I think they solve different problems. Zig gives you more control and will ultimately allow for slightly better performance, but Rust is safer and makes it more difficult to shoot yourself in the foot.

[@pr0master]

Another new language...

[@IsaacHarrisHolt]

Another great new language!

[@xarcaz]

Zig has a lot of cool stuff, but IMHO there's sadly not much point in using it until it gets something equivalent to RAII.

[@IsaacHarrisHolt]

That's a fair take. If you use the larger data structures, and then immediately defer the deinit call, it's not THAT dissimilar to RAII patterns

[@regeleionescu935]

It looks like Java with pub, fn etc. Very verbose, too many words to do something

[@IsaacHarrisHolt]

I disagree, to some extent. Having more reserved words typically makes a language LESS verbose, as you only need a single word to achieve something that takes a lot in other languages (e.g. the `go` keyword in Go). I'm curious which language you're comparing to to form this opinion, though

[@TobiasCastillo-f7u]

The syntax is ugly af. I'll just use C

[@IsaacHarrisHolt]

Syntax should never be a big reason not to use a language. Unless that language is Perl.

[@Little-bird-told-me]

Why bother to learn a new language, where there are no string only arrays defined as [u8], string manipulation function are verbose and clunky, and memory allocators are different paradym. Sure there error handling "try syntax" is good. The complier is your enemy. When we already have Rust why bother with zig ? A simple language with manual memory management and no head files

[@IsaacHarrisHolt]

All your points are very valid! Zig does have some advantages over Rust - it's a bit lower level, and you have more fine grained control over your memory management without having to resort to "unsafe" blocks and so on. Also, comptime is awesome

[@todorelax1793]

pointers? no thanks!!!
