I have been reading about this new language for a while. It’s a C competitor, very slim language with very interesting choices, like supporting cross platform compilation out of the box, supports compiling C/C++ code (and can be used as a drop in replacement for C) to the point in can be used as replacement of ©make and executables are very small.
But, like all languages, adoption is what makes the difference. And we don’t know how it goes.
Is anyone actually using Zig right now? Any thoughts?
The thing that keeps me from loving Zig is https://github.com/ziglang/zig/issues/234
I am too shell shocked to keep thinking of strings as u8[] it’s 2023 for god’s sake.
That issue was marked as resolved but what was the resolution?
Won’t fix
Is there a library being maintained that can handle the concerns?
Yes and no. Sure you can build a library that puts an encoding aware interface on top of strings, but it will cause friction every time the program interacts with something that does not subscribe to the same library, most notably probably the stdlib.
Big oof.
I’ve heard of it, and don’t know what the point is.
In zigs defence, I felt the same way about rust a few years back as well.
I wonder what the killer feature for zig is. At least rust promises safer code, what does zig promise?
I think the main advantages over C are:
- better tooling
- modern syntax
- by default, pointers must be non-null. You have to specify if you want to use null pointers
- better exception handling using the functional style of exceptions-as-values
There are probably more, but those are the ones I remember.
The killer feature (IMO) is automatic conversion of C code to Zig code (transpiling). E.g. take a C project, convert it all to Zig, and even if you don’t transpile, you still get really nice compat (include C headers just like a normal input without converting). Getting a medium sized C project converted to Zig in 1 day or 1 week, then incrementally improving from there, is really enticing IMO especially considering the alternative of rewriting in Rust could be months of very hard conversion work. Transpiling isn’t perfect but it seems to be a 97% soltuion.
The second advantage seems to be easy unsafe work.
BTW I don’t really use Zig, and I still prefer Rust, but those are the reasons I think it has a niche of its own.
I wonder if owners of large C projects are that keen to move off C to zip though? I guess time will tell. I do a fair bit of C, and I can’t see us risking switching to Zig, unless there was something else that made it really worth it. I should probably have a look at Zig if I have spare time, maybe there is a killer feature we aren’t seeing yet.
Easy interop with legacy code is how kotlin took off, so maybe it will work out?
My understanding is that this is possible: you should be able to take a C project, add a build.zig file and under the hood the system is calling clang to compile the C project. HOWEVER, you can now add a .zig source file, compile that in zig and link together with the output of the C compiler into an executable. If this is actually true, I can definitely see the attractiveness of the language.
Easy interop with legacy code is how kotlin took off, so maybe it will work out?
Good interop was a requirement for widespread adoption, but not the reason why programmers want to use it. There’s also null safety, a much nicer syntax, custom DSLs, sealed classes, type inference, data classes, named and optional arguments, template strings, multi-line strings, computed properties, arbitrary-arity function types, delegation, custom operators, operator overloading, structural equality, destructuring, extension methods, inline functions and non-local control flow, reified types, …
Some of these features have since been added to Java.
I wasn’t trying to diminish the value of Kotlin, my point was that interop makes it so easy to stealth insert it into legacy java codebase, and that probably contributed heavily to it’s success?
Language adoption is a multi-part problem, you ideally need good interop (or upgrade path) and your language needs to also be compelling enough to upgrade to. Zig certain seems to have the former, I’m not personally sold on the latter, but it certainly sounds like it might have some compelling features.
It competes with C, so in 2023 this basically means embedded systems. It offers executable size of few KB and out-of-the-box cross-platform compilation. It’s a modern C, basically, and it claims to be even faster than C as some language rules allow more optimizations
This talk is technically not about Zig, but he still shows many of Zig’s strengts: https://youtu.be/aPWFLkHRIAQ?si=b-rf_oM*removed*IvAdq
To me, Zig is a language that tries to be like C, but with all the decades of mistakes removed, or rather with modern knowledge of good language design in mind, while keeping as much compatibility as possible, as to not require a lot of work for the transition as Rust did. Thus, if you’re working in a C codebase, you’ll be good to go to integrate Zig in as little as an hour. They also have by far the cleanest solution to macros and generics that I have seen yet (although I miss my type classes).

It promises more correct code. As an example, most rust code and in fact most crates you will find will treat a memory allocation failure as an irrecoverable error, ie. your program will just crash.
In Zig, such error classes are not supposed to exist by definition, making the resulting programs more robust.
How does zig solve the memory allocation failure issue? RAM isn’t unlimited, it has to fail eventually?
It does not “solve” memory allocation failures, as its not a thing that can be solved. It exposes memory allocation in a way that forces you as a programmer to handle the possible error situation. You cannot just call
mallocornewor what have you and the just move on as if nothing happens.Oh right, okay. I thought you meant that allocations just couldn’t fail.
Instead you are just forced to handle it properly if it does fail. Would be very interested to test that in practice. C memory allocations are notoriously tolerant, and will happily let you allocate terabytes of memory that doesn’t really exist until you try write to it.
I’ll definitely have to give that a play at some point.
Ah, that is another thing that Zig does well (in my opinion). Instead of having a global allocation call, Zig uses an
allocatorinterface interface, meaning you as the programmer can plug in different allocation strategies as you require. So depending on if you do or don’t like that behavior, just pick the allocator accordingly, either for your whole program or just for parts of it.
zig’s biggest feature is comptime. completely removes need for generics as types exist as first class at compile time. also all functions can run at comlile time. no exceptions.
for example theVecfunction accepts a type as and returns a struct that can hold arbitrary amounts of said type on the heap.
I really don’t see what niche it is trying to fill that isn’t already occupied.
Rust is as successful as it is because it found a previously unoccupied niche: safe systems programming without garbage collector and with high level abstractions that (mostly) optimise away.
I don’t think “better C” is a big enough niche to be of interest to enough people for it to gain a critical mass. I certainly have very little interest in it myself.

BTW I don’t really use Zig, and I still prefer Rust, but those are the reasons I think it has a niche of its own. Does rust already fill this space? Yeah kinda, but that’s why I’d call in a niche
comptime is a huge killer feature for me. I used it to generate ARM lookup tables at compile time and it’s amazing, it also removes the need for generics as types are just arguments
for example theVecfunction accepts a type as and returns a struct that can hold arbitrary amounts of said type on the heap.
I eventually switched to rust + proc macros tho (zig solution was MUCH cleaner!) because both ZLS and the Zig compiler are terrible and still needs a lot of work.Yeah my thinking as well.
Addtionally, why I think other system language competitors like Zig or Nim aren’t succeeding long-term, is because of fast growth and already big ecosystem of Rust. Zig may be better though for some use-cases (when you want to avoid all the mental overhead, and the application stays simple).
I’ve heard of it for sure, and have seen some examples. I’ve never seen a real good use case for my personal or professional projects that I couldn’t fulfill with Rust or Dart in the same capacity or better. Then again, I don’t work with C projects basically at all, so other people’s mileage may vary.
I also prefer Rust, but I saw a pretty good argument for Zig (and actually a pretty big hole/problem with Rust) when it comes to unsafe stuff. The title of this is clickbait but the content is really good: https://www.youtube.com/watch?v=CbQVR4v5PZw

His clickbaity nature is what makes ThePrimeagen successful I’d argue
Yes some people are using it! I think this video gives a good idea of adoption since its about a company’s experience using zig: https://www.youtube.com/watch?v=wxx5_Xaw7zU
I considered Zig and Nim as kind of irrelevant given Rust is being adopted, but this video, specifically the C compat, changed my mind, at least for Zig.

good bot
I started hearing of it in 2021. Read through the documentation in February of 2022 and started to learn it in Fall of 2022. Ever since then I use both, Rust and Zig depending on the small project or concept I currently want to explore.
I wrote a blog post that describes the 3 things I like about both languages each: https://zigurust.gitlab.io/blog/posts/three-things/
Might be interesting.
Well, there’s the focus text editor
but, at least when I tried it, you had do change the code just to compile it in Linux. Even tho it has a Linux “compatible” version.
Its a neat language, very simple. Has a somewhat simple approach to codegen at compile time, which is both a boon and a curse; you can do a lot with it, and not get too deep into footgun territory, but once you hit the limits of what you can do, you’re pretty much stuck there.
The syntax and other features are very nice, and it makes rather small binaries. I’d say its comparable to Nim in this area.
Sadly, it also suffers the same problems Nim suffers: dearth of libraries.
Sadly, it also suffers the same problems Nim suffers: dearth of libraries.
That might change once the language stabilizes. Imagine creating a library now and the language changes breaking it.
would transpilation of C libraries help with the lack of libraries however?
In theory yes, but it becomes a problem of ergonomics. The transpiled library feels like a transpiled library, it doesn’t match the conventions of Nim/Zig. The best ports/wrappers/whatever typically use the C lib for all the heavy lifting and unique things, and build their own interface, that matches conventions of the calling language
Syntax is too confusing. Instead of looking like code it looks like a wall of pure text instead. Also too strict to do basic stuff
I’m not super interested in the language at the moment, simply because the two I currently use most (Go and Rust) cover all of my use cases. It does sound quite promising though and I like the governance model.

Never heard of it.
Take off every “Zig.”
You know what you doing.
For great justice.
