From 1a0011e0f4a5bbcc6e16c7017a19d315235e3b98 Mon Sep 17 00:00:00 2001 From: Denis Arnst Date: Sun, 14 Dec 2025 15:41:35 +0100 Subject: [PATCH 01/13] C++ Rewrite MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rewrite codebase from C to modern C++20 Complete modernization introducing type safety, better error handling, and a cleaner architecture. - **Language**: C → C++20 (requires GCC 10+, Clang 10+, MSVC 2019+) - **Structure**: Reorganized into lib/, cli/, tests/ - **Error handling**: Result type with rich error information - **Device code**: 50-70% reduction via protocol templates - High-level C++ API (headsetcontrol.hpp) - C API for FFI bindings (headsetcontrol_c.h) - Shared library support (-DBUILD_SHARED_LIBRARY=ON) - Protocol templates: HIDPPDevice, SteelSeriesNovaDevice - Data-driven capability system - Test suite - HIDDevice base class with virtual methods per capability - Device registry singleton for device lookup - Capability descriptors as single source of truth - Feature handler registry (replaces switch statements) CLI interface unchanged - fully backwards compatible. - See docs/ADDING_A_DEVICE.md for adding devices - See docs/ADDING_A_CAPABILITY.md for adding features - See docs/LIBRARY_USAGE.md for library integration CI: Use GCC 13 on Ubuntu, add verbose test output ---

rewrite of HeadsetControl from C to modern C++20, introducing: +- Type-safe error handling with `Result` +- RAII resource management +- Protocol abstraction templates +- High-level library API +- Comprehensive test suite + +## Breaking Changes + +- **Minimum C++ standard**: Now requires C++20 (GCC 10+, Clang 10+, MSVC 2019+) +- **Project structure**: Code reorganized into `lib/`, `cli/`, `tests/` +- **Header extensions**: Changed from `.h` to `.hpp` for C++ headers + +## New Features + +### High-Level Library API + +New `headsetcontrol.hpp` provides a simple, HID-abstracted interface: + +```cpp +#include + +auto headsets = headsetcontrol::discover(); +for (auto& headset : headsets) { + if (headset.supports(CAP_BATTERY_STATUS)) { + auto battery = headset.getBattery(); + if (battery) { + std::cout << battery->level_percent << "%\n"; + } + } +} +``` + +### C API for FFI + +New `headsetcontrol_c.h` provides a pure C interface for bindings: + +```c +hsc_headset_t* headsets; +int count = hsc_discover(&headsets); +// ... use headsets ... +hsc_free_headsets(headsets, count); +``` + +### Result Error Handling + +All device methods now return `Result` with rich error information: + +```cpp +auto result = device->getBattery(handle); +if (result) { + // Success: access result->level_percent, result->status, etc. +} else { + // Error: result.error().code, result.error().message +} +``` + +### Protocol Templates + +Reusable protocol implementations reduce device code by 60-80%: + +- `HIDPPDevice` - Logitech HID++ protocol +- `SteelSeriesDevice` - SteelSeries protocol family +- `CorsairDevice` - Corsair iCUE protocol + +### Rich Result Types + +New structured result types with extended information: + +- `BatteryResult` - level, status, voltage, time estimates +- `SidetoneResult` - level with device range info +- `ChatmixResult` - level with game/chat percentages +- `EqualizerInfo` - bands, range, step size + +### Data-Driven Feature System + +New capability descriptor and handler registry system: + +- `CapabilityDescriptor` - Single source of truth for all capability metadata (CLI flags, descriptions, value ranges) +- `FeatureHandlerRegistry` - Dispatch table replacing giant switch statements +- Automatic parameter validation from descriptors +- Auto-generated help text value hints from descriptors + +```cpp +// All capability metadata in one place +inline constexpr std::array CAPABILITY_DESCRIPTORS = {{ + {CAP_SIDETONE, CAPABILITYTYPE_ACTION, "sidetone", "-s", "Set sidetone level", 0, 128, "<0-128>"}, + // ... +}}; + +// Feature execution via registry +auto result = FeatureHandlerRegistry::instance().execute(cap, device, handle, param); +``` + +### Shared Library Support + +- `BUILD_SHARED_LIBRARY` CMake option for creating dynamic library +- Windows DLL export macros (`HSC_API`) +- Versioned shared library with SOVERSION + +### Comprehensive Test Suite + +- Unit tests for utility functions (67 tests) +- Mock device tests +- Integration tests +- Test device with all capabilities + +## Architecture Changes + +### Project Structure + +``` +HeadsetControl/ +├── lib/ # Core library +│ ├── devices/ # Device implementations +│ │ ├──
