v0.2.0: gputypes integration

gputypes Integration Release

This release integrates go-webgpu with the gogpu ecosystem through github.com/gogpu/gputypes.

⚠️ Breaking Changes

• All WebGPU types now use github.com/gogpu/gputypes directly
  • Example: wgpu.TextureFormatBGRA8Unorm → gputypes.TextureFormatBGRA8Unorm
  • Enum values now match webgpu.h specification

✨ Added

• Integration with gogpu ecosystem via gputypes
• Full webgpu.h spec compliance for enum values
• Comprehensive conversion layer for wgpu-native v27 compatibility
  • TextureFormat (~45 formats), VertexFormat (~30 formats)
  • Wire structs with correct FFI padding (uint64 flags)

🐛 Fixed

• TextureFormat enum values mismatch (BGRA8Unorm was 0x17, now correct 0x1B)
• Compatibility with gogpu Rust backend
• All 11 examples now work correctly

📦 Dependencies

• goffi v0.3.7 (ARM64 Darwin improvements)
• wgpu-native v27.0.4.0

Migration Guide

// Before (v0.1.x)
import "github.com/go-webgpu/webgpu/wgpu"
format := wgpu.TextureFormatBGRA8Unorm

// After (v0.2.0)
import (
    "github.com/go-webgpu/webgpu/wgpu"
    "github.com/gogpu/gputypes"
)
format := gputypes.TextureFormatBGRA8Unorm

Full Changelog: v0.1.4...v0.2.0

v0.1.4

ARM64 Darwin Improvements

Update goffi v0.3.6 → v0.3.7

Improved

• Comprehensive ARM64 Darwin support — tested on M3 Pro hardware
• Nested struct handling — proper layout for complex struct types
• Mixed integer/float struct support — automatic struct layout computation
• Struct returns 9-16 bytes — Call8Float now returns both X0 and X1 registers

Fixed

• Segmentation fault in string output benchmarks on Darwin

Contributors

• @ppoage — ARM64 Darwin implementation, Objective-C test suite, assembly verification

v0.1.3

ARM64 HFA Fix

Update goffi v0.3.5 → v0.3.6

Fixed

• ARM64 HFA returns — NSRect (4×float64) now correctly returns all values on Apple Silicon
• Large struct returns — Structs >16 bytes properly use X8 register for implicit pointer passing
• Blank window on macOS ARM64 — GPU dimensions no longer return 0×0

Fixes gogpu#24

v0.1.2

Update goffi dependency v0.3.3 → v0.3.5

v0.1.1 - Hotfix

Summary

• golang.org/x/sys: v0.38.0 → v0.39.0

Fixed

• Critical bug in PointerType argument passing (goffi#4)

Infrastructure

• Branch protection enabled for main
• All changes now require Pull Requests
• Updated CONTRIBUTING.md with PR workflow
