📝 Walkthrough

Walkthrough

The package now requires Zig 0.16.0. Internal NIL construction, benchmark buffers, benchmark separators, and test fixtures use updated Zig initialization syntax. Exported declarations and behavior remain unchanged.

Changes

Zig compatibility updates

Layer / File(s)	Summary
Compiler baseline and NIL syntax `build.zig.zon`, `src/msgpack.zig`, `src/test.zig`	The minimum Zig version changes from `0.14.0` to `0.16.0`. NIL payload construction now uses `{}` instead of `void{}`.
Benchmark initialization and separators `src/bench.zig`	Benchmark buffers use `@splat`, medium strings use concatenated `base` strings, and output sections reuse precomputed separators.
Test fixture initialization `src/test.zig`	String boundary and PackerIO tests use fixed-size byte arrays with `@splat` or array references.

Can you do some compatibility work? I don't want to drop support for 0.16.

burakssen · 2026-08-19T07:49:45Z

Can you do some compatibility work? I don't want to drop support for 0.16.

Sure, I'll try to complete until tomorrow.

burakssen · 2026-08-20T19:48:43Z

Hi, I just checked, and all the code works with both Zig 0.16.0 and 0.17-dev. Should I just update the minimum_zig_version in build.zig.zon? It was previously set to 0.14.0, so should I change it to 0.16.0 or leave it at 0.14.0?

jinzhongjia · 2026-08-21T06:20:53Z

0.16.0

jinzhongjia · 2026-08-21T06:21:16Z

I've been quite busy with work lately, so I might merge this PR later.

jinzhongjia · 2026-09-04T20:17:10Z

Oh,I will check this today!

 - Provides a `BufferStream` implementation for Zig 0.16+ that mimics the behavior of the old `FixedBufferStream`
- Uses conditional compilation to maintain backward compatibility with Zig 0.14 and 0.15
- Ensures all existing functionality works seamlessly across different Zig versions
+- Keeps the same buffer-stream API on Zig 0.16 and 0.17 development builds
+- Is exercised by CI on Zig `0.16.0` and the latest `master` development build

-This means you can use the same API regardless of your Zig version, and the library will handle the differences internally.
+The current minimum supported Zig version is `0.16.0`; older compatibility branches in the source do not imply support for older compilers. Code formatting is checked with Zig `0.16.0`, since development compiler formatters may introduce syntax migrations.


📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Update all stale Zig support guidance in AGENT.md and CLAUDE.md. These tracked instruction files still claim Zig 0.14/0.15 support and reference the removed CI matrix. They also contain stale compatibility checks and examples. Align them with the Zig 0.16.0 minimum, master development support, and current CI workflows. No other checked-in support or CI configuration requires this update.
