I got involved to multiple debates regarding recent events, then I realized that some people just came to this forum to watch this language development, and judge it by its cover, without actually using it. After judging, unfortunately, they joined the debates, and provided others with inaccurate...
Hashiwokakero ( Hashi Bridges ) Source Code Play the Web Version Here A zig implementation of the popular japanese game “Hashiwokakero”, using the raylib-zig binding for the graphics. This is my first project using zig, I’m much more familiar with C/C++, for example. I wanted something about e...
Anytime i use any of these tools to launch my MMO’s server they always crash on .INVALD => unreachable,. Otherwise, the server runs normally. In my server I initialize a player list in main players: std.MultiArrayList(struct { player: Player, socket: std.posix.pollfd, aid: common.A...
Hi everyone, This was the topic that finally motivated my first post here. Not to try and litigate it, but try and understand it, and perhaps ask what to do about an edge case if the long considered removal were to be accepted one day. I’m pretty new to Zig, but feel I’ve gotten pretty far. I’v...
Good breakdown of Data Oriented Design for parsers.
/// return true if /// a = b; // a: Afunc, b: Bfunc /// won’t cause a compile error fn match_function_type(Afunc: type, Bfunc: type) bool simply Afunc == Bfunc is not all the cases. by the way, is there a way to capture the compile error?
I just had plain c.sdl* functions and I decided that I want to strip them to sdl.* Gnerally it is just about trying to find a way to create decls for comptime generated struct (As a probably a lot of people tried: example1, example2). And I found one way! In zig you can do following: // It is...
This test: const run = b.addSystemCommand(&.{ b.graph.zig_exe, "fetch", "--no-unpack=subpath/../example_dep_file.txt", }); run.addFileArg(b.path("example/example_dep_file.txt")); run.expectExitCode(1); run.expectStdErrMatch("--no-unpack path may not contain '..' components"); test_st...
I see some posts here example that older versions of zig allowed to retrieve function names via @typeInfo but I try to do it and there are only field names… const anon = struct { tte: u32, pub fn ttr() void {} }; const stripped = stripNamespace(anon); pub fn main() !void { stripped....
I’m making an abstraction over Vulkan based on No Graphics API and I’ve been debating how to represent gpu side pointers on cpu, here’s a small snippet of what it looks like right now in my user code so you get the idea: const Data = extern struct { particles: *anyopaque, // gpu pointer,...
I know there are a few of us in Portland, and pride is this weekend. Anyone want to meet up for lunch on Sunday after the parade? If nobody suggests an alternative, my default plan is Veggie Grill @ 1PM since it’s easy and near the festival/parade route. I’m open to suggestions though, I rarely...
While doing Advent of code 2015 day 13 I realized I needed to make some combinations of people around a table. Turns out this concept is called a permutation and well, one thing led to the other until I made my first library ever. You can find it here: https://codeberg.org/T3kla/plain-changes A...
Richard’s style of writing is less similar to mine than Andrew’s or Mitchell’s: he reads as a bit more generous and takes time to say things that I might just leave to a reader to notice. Excellent move, to move up this blog post ahead of the 0.1.0 announcement, given current events 😉 Anyway,...
cons buffer: []u8 = std.Io.Dir.readFileAllocOptions(...) // with align 4 gpa.free(buffer); gives an error thread 17498 panic: free of [addr: 776193d598a0, len: 1408 (0x580) align: 1] mismatches allocation of [addr: 776193d598a0, len: 1408 (0x580) align: 4] I know about .rawFree which has an a...
How would you do cross platform atomic/tmp dirs? I was thinking of using knownfolders .runtime with some random hex name and then renaming it into place, but unsure how to handle cleanup(i.e. should I do any?)
I’d really like to use ReleaseSafe builds by default, but I keep finding them unreasonably slow. A common source of slowdowns is var large_buf: [N]u8 = undefined. If you have something like that in the hot path, it has meaningful impact. I’ve seen some other thread that memset is not actually as...
I currently try to implement an fs for which I require positional reads/writes. For testing purposes I would like to have the implementation only take *std.Io.Reader and *std.Io.Writer instead of an *std.Io.File, but I noticed that the interfaces don’t expose positional reads/writes, not even se...
Cruller: a production-focused Bun runtime ported to Zig 0.16 Cruller is a fork of the last Zig-based Bun release, reduced to the parts needed to run already-built production JavaScript servers and ported to vanilla Zig 0.16. Repository: GitHub - solenopsys/cruller: fork of Bun · GitHub The proj...
// The two are less consistent. const v = T{.x = 1, .y = true}; // why not T.{.x = 1, .y = true} ? const v: T = .{.x = 1, .y = true}; // The two are more consistent. const v = T.declOrTag; const v: T = .declOrTag;
Hey 🙂 this is my first Post and also my first attempts at metaprogramming. For my Project im working on, i needed some icons and found them in the form of SVGs. Because i want this project to be small and minimal, and because i need the icons the whole time the Program is running, i want to em...
Hello, i would like to write zon in such a way that, i could omit struct fields and their value would default to whatever code i write for them example // when i parse this, i check if the optional bool is present in the zon. // if not, default it to "false" const Foo = struct { required_int...
Zaman Zaman (زمان in Persian) is a memory safety tool for Zig that tries to prevent use-after-free and ifetime confusion at compile time by encoding arena lifetimes directly into pointer types. Why does this exist? I have several die-hard Rustacean friends who were constantly bragging about...
Hi! Please tell me, what is the latest version of C++ supported by the zig c++ compiler? Thanks!
Railroad It’s a railroad diagram generator that comes with a live server for editing. This all started as a search for a way to add railroad diagrams to https://ziggy-lang.io and ended up in a small rabbit hole. I’ll soon add this to Zine to let authors place a diagram source in their cont...
Hi all, I’ve been working on a node editor using Vulkan and Wayland. I am playing around with creating my own version of MaxMSP, which is a node editor that can be used essentially to create sound graphs where each node is a source, a filter, etc. It is often used for prototyping, but also for o...
this is a function from my vector library, it sets the X axis of a vector (the first element in a SIMD vector) to the provided value. question is: how would the compiler handles this given that dimensions is a comptime_int and so it is comptime known, would it make a copy of the function for eac...
I wrote a small command line argument parser and I would now like to test it. The parser takes a std.process.Args.Iterator for initialization like so: const args: std.process.Args = .{ .vector = &.{ "--asdf", "--qwerty", "--", "-abc", "waow", "woah", "hmmm" }, }; var iter: ArgsIterator = .in...
Zero Sugar Added A zig-only game jam, with a unique gimmick for each jam, focused on limiting you in fun ways! A couple of months ago, me, @evaleek and @Sietse2202 decided we wanted to host a zig gamejam to show our love for the language, game development, and the community! As said above, the...
xsync.zig This project implements a new set of synchronization primitives that work across std.Io instances. std.Io.Mutex and friends wake waiters through whichever Io the waker happens to run on. That works when everything shares one parking implementation, but a waiter parked through one Io i...

decache Have you ever thought to yourself: “Gosh dang it, all these .zig-cache directories are taking up so much space on my disk, but I have so many projects it would take AGES to clean them all up! What ever could I do?” decache lets you easily clean up all directories that match a pattern,...
I don’t know what tool I really need but I would like (to shoot my leg again) and just have force cast So I have two C libraries (both of which I independently use) and one of them exposes API which takes as parameter type from another one //lib1.h struct lib1_struct {...} //lib2.h #include <l...
Hi! How many times does the import function include the standard library in each translation unit? Is it cached or included in every translation unit, as in C++? If I worded the question incorrectly, forgive me! Thanks!
Hello, i am having an issue where i am getting seg fault on a seemingly random spot of the code. using a step debugger, the path to crash is -> array_list.zig 1142:26 -> allocator.zig 360:18 -> allocator.zig 448:5 -> compiler_rt.zig 684:14 Segmentation fault at address 0x7f0d40580000 lib/std/m...
stdio-zig A teensy library that wraps stdin/stdout behind a clean, buffered API for Zig’s new std.Io interface (0.16+). https://github.com/tacheraSasi/stdio-zig In all my CLI projects I found myself writing the same three things over and over: allocate buffers, wire up stdout/stdin readers and...
klack is a lightweight, zero-configuration mechanical keyboard sound simulator for Linux. It runs seamlessly in the background, listens directly to your selected input devices, and is designed to be easily managed as a standard systemd user service. The application is completely agnostic to the...
Hello, Ziglings! How do I get Zig to work with GTK 4? Creating forms and controls. Thanks!
I am writing an application that needs, at runtime, to download resources from the internet and pre-process them. But I want to skip the work on subsequent launches. This seems exactly the problem solved by build.zig. Is there a nice way to re-use that in my application? The brute-force would be...
Hi, recently ive been having to create runtime arrays where i have some data to iterate over and append it to an array, and although i have a way that works (and even think is the proper/accepted way) One of my usecases: create an array of the cli arguments. Solution: pub fn argsToArray(gpa: st...
While working on my emulator project I’ve noticed that size of the zig-cache directory can grow really fast and can easily pass the 200GB in size. Has the core team looked into this issue yet?
Hello. I’m having issues with 0.16 when targeting wasm32-emscripten and as far as I’m aware it’s a known problem. Latest 0.17 works fine, but ZLS stops working and it’s hard to work without an LSP. ZLS explicitly states: use Zig 0.17.0-dev.387+31f157d80 with master branch ZLS So 0.17.0-dev.38...

Is there a way to send ancillary data with 0.16 Io, and if not, is there a way to cleanly integrate it into the io system?

I’m currently working on a hobby OS (which I may also post about if I ever finish getting to userland), and I’ve been running into build issues on CI only on macos and windows (which I can only replicate on github CI since I work on this project mostly on my linux box). I pull in various project...
Is there are feature on this site so that I could add custom tags to users? For example: It would be nice to be able to add a note to people to say what project they’re working on (if they’ve shared it). That way I’m not relying on my memory to realise “Oh, that’s the one that’s working on a che...
I see no problem with having a bunch of @compileLogs here and there even after the testing is done. One annoying thing I currently have to deal with, is I have to look at the comptime logs and runtime logs. To do that, have to look at the comptime logs, comment all them out, and build it again to...
I have am making an application that requires CAP_NET_RAW. I would like to include a convenience run step so I can change my current workflow: zig build sudo zig-out/bin/gatorcat --log-level err dc --ifname enx00e04c68006a --recv-timeout-us 50000 --config-file eni.zon to this: zig build run --...
Hey folks, I’ve noticed a few people posting here about having issues with translate-c since 0.16.0. I’ve been actively helping out with resolving some of the outstanding issues with Aro and translate-c as we work to update Ghostty to 0.16.0. I’m currently maintaining a branch with mostly up-to...

I can’t find a better title for this. What I’m asking for example: const arr: std.ArrayList(usize) = .empty; Is there a method that let me check if arr is an instance of the generic ArrayList struct. My main use for this is to make my own json parse that support zig first party structs without...
regrex: regrex means regret + regex. Something a lot of developers can relate to - an inescapable dread of processing text and having to utilize regular expressions, the meaning of which even the best can forget in two weeks or so. regrex is a small and primitive implementation of a regular exp...
I need to create a map with amino acids as keys and values that represent their mass (f32). Amino acids, the building blocks of proteins, are represented by a single capital letter–there are just 20 of them. I created the working solution below that uses string keys, but is there something simila...
https://codeberg.org/krl/zig-ts-mode Hello all fellow emacsians, i have made a minimalist ts mode for emacs that i have been running for a while now. The other zig-ts-modes i have found have either been incomplete or outdated, as well as containing a lot of stuff that i don’t need and/or unders...
I’ve been writing a small program (that I’m hoping to showcase soon!) that needs to walk a directory tree to do its job. The basic code I want to write is as follows: while (walker.next()) |ok| { const entry = ok orelse break; // walker is finished // do stuff with entry... } else |err|...
Just to clean mess in my head. Let’s suppose that we have two “execution contexts”: under Io.Threaded under Io.Evented And shared struct with Io.Mutex used guard As far as I understand the way of safely access to this struct is use “neitral” 3rd Io - std.Io.Threaded.global_single_thr...

Hello, I was wondering how MultiArrayList.deinit interacts with a MultiArrayList obtained with .empty? I see empty is defined as follows: pub const empty: Self = .{ .bytes = undefined, .len = 0, .capacity = 0, }; … and deinit as follows: /// <SNIP> fn allocatedBytes(self: Self) []a...
I have (almost) never done anything with simd operations. Time to play around with it. When I want to bitwise combine the following (chess) struct would that be a good candidate for simd (instead of ‘manually’ combine all fields with another Threats struct)? Operations like and, or, xor. Or so...
assembly-zig I spent some time learning assembly and took the opportunity to do so while also trying to interact with Zig code from assembly and vice-versa. I learned a lot about calling conventions, X86 assembly, Zig – at the time 0.16.0 wasn’t tagged yet so I also got to experiment with the...
I was playing with TSan, adding instrumentation to zio so that it can detect coroutine switches and was very surprised it flagged some of my internal code. It turns out if I do &self.foo.bar to take the reference, Zig 0.16 in debug mode (both self-hosted and LLVM) actually copies the entire self....
I finally hit a scenario where i need dynamic error messages to be shown to an end user for binary decoder i am busy with. This naturally led me to discover the diagnostics pattern, which I see has been discussed a few times on this forum. The idea made a lot of sense and I looked at some example...
I am adding native file dialog extended as a dependency to my project, and I am using portal instead of gtk to avoid X11 conflicts with glfw.zig. When compiling to x86_64-linux (not native), I get: error: error: unable to find dynamic system library 'dbus-1' using strategy 'paths_first'. searched...
I only discovered today that both the debug allocator (gpa) and the smp allocator indefinitely caches small/medium allocations. Firstly is this correct? If the above is correct, what would a good way be to have some global backing allocator(s) for my http request based arena allocators. However...
wssup - simple WebSocket client library Hi Ziggit! A couple of months ago I was writing a NetworkTables client in Zig and needed a WebSocket client library (the standard library only has WebSocket server support). So I used karlseguin’s websocket.zig, but I didn’t like it because of how bulky...
I’m trying to include licenses / readmes from my dependencies in my project, as well as bundle dependency source code with my releases to comply with copyleft licenses (Im statically compiling to a lone executable). However, some of my dependencies exclude their readme/license from their build.zi...
Hello everyone, There is this project which looks way better than use electron for desktop applications based on web technologies: I am wondering if there is any similar project for zigo. or, if what ould be the errort to consume this from zig. any thougts on this?
Around some time last year I’ve decided to give Zig a try and the best way to learn a new language is to build a project with it. So after spending some time thinking about what to build, I’ve decided to build an emulator because I was always curious to know how emulators worked, thus NESkwik was...
scdoc – Zig package I made a tiny wrapper for Drew DeVault’s scdoc, a simple man page generator for POSIX systems. The wrapper uses zig cc to build scdoc from the original C sources, while providing convenience functions when used as a dependency for Zig projects. If you use the built-in option...

I found this a nice antidote to the emotionally charged Zig news cycle of the last 24 hours. a lot to love, but this line made me smile: Zig is just getting better and better. They focus a lot on compilation tooling and even removed language features to improve compilation speed, mind blowing....
Hey all, I fell in love with zig while exploring it this summer and I kind of look at it as a language that can actually be the forefront of low level parts of ML/AI in the future. Hence, I have been working on zcore, a tensor library in Zig, and wanted to share it early while the core design is...
Suppose I have a fairly large amount of possible values in a switch, and need to check a few of them for special behavior and most of them for default behavior, but I also have some values that are forbidden. Is that doable inside a switch? switch (value) { 0, 1, 2 => do_this(), 3, 4, 5...

I’m trying to automate getting licenses and readmes from my dependencies, as well as urls in order to link to library source code in my gui (I’m trying to statically compile, and I want to be extra cautious about copyleft compliance). Right now, there seems to be no built-in way to parse the zon...
I know the community was pretty split on Jared Sumner’s decision. Now, we get to read his thoughts on the move and appreciation for Zig.
Hello everyone, I have a question about using realloc on an aligned slice. Say I have a struct with an aligned slice like this: struct { ... data: []align(64) i32, ... } And I initialize it with a capacity of 9: allocator.alignedAlloc(i32, mem.Alignment.@"64", 9); My understandi...
I’m running into an odd comptime issue when I was trying some sample code using evented + Grand Central Dispatch, and I’m not quite understanding it. I suspect this is just a standard library bug but I’m still not positive that it isn’t user error. The issue happens for me on both master (0.17.0-...

Zig Asset Bundler Compress and embed directories into your Zig executable. This is a first initial release, I plan to use it in Zine because the Zine executable needs to contain all the assets that are part of the template website you get when you run zine init. As the readme says, I would l...
nanozlog: Hello! This is my first post in the community. I’m glad to introduce my small zig library: nanozlog. It is basically porting from the famous C++ logging library: fmtlog. It is mainly focusing on the frontend logging speed. It could achieve 6-7ns per message which will cause the smalles...

I somewhat recently cleaned up the sokol-zig build.zig file and added a manual build step for installing the Emscripten SDK via zig build install-emsdk (previously this was done ‘on demand’ when doing the first build with target wasm32-emscripten). Now of course I have the problem that this new...
