From bf46e44e1cb6027a072819a2a3aa3be32651f6e1 Mon Sep 17 00:00:00 2001 From: skal Date: Tue, 3 Feb 2026 18:44:41 +0100 Subject: refactor: Task #20 - Platform & Code Hygiene - Consolidated all WebGPU shims and platform-specific logic into src/platform.h. - Refactored platform_init to return PlatformState by value and platform_poll to automatically refresh time and aspect_ratio. - Removed STL dependencies (std::map, std::vector, std::string) from AssetManager and Procedural subsystems. - Fixed Windows cross-compilation by adjusting include paths and linker flags in CMakeLists.txt and updating build_win.sh. - Removed redundant direct inclusions of GLFW/glfw3.h and WebGPU headers across the project. - Applied clang-format and updated documentation. handoff(Gemini): Completed Task #20 and 20.1. Platform abstraction is now unified, and core paths are STL-free.

Removed STL containers (`std::map`, `std::vector`, `std::string`) from `AssetManager` and procedural generators. - **Task #26: Shader Asset Testing & Validation**: Developed comprehensive tests for `ShaderComposer` and WGSL asset loading/composition. Added a shader validation test to ensure production assets are valid. - **Asset Pipeline Improvement**: Created a robust `gen_spectrograms.sh` script to automate the conversion of `.wav` and `.aif` files to `.spec` format, replacing the old, fragile script. Added 13 new drum and bass samples to the project. - **Build System Consolidation (Task #25)**: Modularized the build by creating subsystem libraries (audio, gpu, 3d, util, procedural) and implemented helper macros to reduce boilerplate in `CMakeLists.txt`.
