Next Steps - -## Current Status ✅ - -The parser is **functional with dependency resolution** and includes: -- All C declaration types supported (opaque, enum, struct, flags, functions) -- Proper naming conventions implemented ("first underscore" rule) -- Memory leak free (validated with GPA) -- 18+ unit tests, all passing -- **NEW: Dependency resolution system** ✅ - - Automatic detection of missing types - - Extraction from included headers - - Single-file output with dependencies - - Successfully resolves 4/6 types from SDL_gpu.h dependencies -- Comprehensive documentation under `docs/` -- Successfully parses SDL_gpu.h (169 declarations) -- Mock code generator complete - -## Recently Completed (2026-01-22) - -### ✅ Phase 1: Dependency Resolution Infrastructure - -**Implemented**: -- `src/dependency_resolver.zig` - Complete dependency analysis system -- Type reference scanning (finds SDL types in signatures) -- Include directive parsing (`#include `) -- Selective type extraction from headers -- Declaration deep cloning with proper memory management -- Integration into main parser workflow -
