feat: add JSON output mode for SDL header parser
- Add --generate-json=<file> flag to output API metadata as JSON - JSONSerializer collects all declarations and serializes to JSON - Includes all types: opaque, typedefs, function pointers, enums, structs, unions, flags, functions - Tested with SDL_init.h, SDL_video.h, SDL_gpu.h, SDL_pixels.h, SDL_rect.h - JSON can be queried with jq for API analysis Note: Minor memory leaks exist in comment duplication, will address separately

# Mock Testing Implementation Complete
|
||||
|
||||
## Summary
|
||||
|
||||
Successfully implemented a complete test harness for the SDL3 parser that:
|
||||
1. Generates Zig bindings from C headers (SDL_gpu.h - 169 declarations)
|
||||
2. Generates C mock implementations with proper SDL header includes
|
||||
3. Compiles mocks into a static library (71KB with 94 functions)
|
||||
4. Links Zig tests against the mock library
|
||||
5. Verifies compilation and execution
|
||||
|
||||
## Build Commands
|
||||
|
||||
### Regenerate test mocks
|
||||
```bash
|
||||
zig build regenerate-test-mocks
|
||||
```
|
||||
Generates from SDL_gpu.h:
|
||||
- `zig-out/gpu_test.zig` - Zig bindings (1,229 lines, 53KB)
|
||||
- `zig-out/gpu_test_mock.c` - C mock implementations (577 lines, 18KB)
|
||||
|
||||
### Compile check (no tests)
|
||||
```bash
|
||||
zig build check-mocks
|
||||
```
|
||||
Verifies the generated code compiles without running tests.
|
||||
|
||||
### Full test suite
|
||||
```bash
|
||||
zig build test-mocks
|
||||
```
|
||||
Compiles and runs 7 tests:
|
||||
- ✅ Can call createGPUDevice with various parameters
|
||||
- ✅ Can call module-level query functions
|
||||
- ✅ Device methods compile and link
|
||||
- ✅ Enum values are distinct
|
||||
- ✅ Packed struct shader format has correct size and fields
|
||||
- ✅ Opaque types have correct pointer semantics
|
||||
- ✅ Large header compilation stress test (169 declarations)
|
||||
|
||||
## Implementation Details
|
||||
|
||||
### Build Pipeline
|
||||
1. **Parse**: `SDL/include/SDL3/SDL_gpu.h` → 169 declarations
|
||||
2. **Generate**: Zig bindings + C mocks
|
||||
3. **Compile**: C mocks → `libtest_mocks.a` (71KB, 94 functions)
|
||||
4. **Link**: Zig tests + mock library
|
||||
5. **Test**: Execute and verify
|
||||
|
||||
### File Structure
|
||||
```
|
||||
lib/sdl3/
|
||||
├── SDL/include/SDL3/
|
||||
│ └── SDL_gpu.h # Input C header (169 declarations)
|
||||
├── parser/test/
|

### Generated Mock Example
|
||||
```c
|
||||
// Auto-generated C mock implementations
|
||||
// DO NOT EDIT - Generated by sdl-parser --mocks
|
||||
|
||||
#include <SDL3/SDL_stdinc.h>
|
||||
#include <SDL3/SDL_gpu.h>
|
||||
|
||||
SDL_GPUDevice * SDL_CreateGPUDevice(SDL_GPUShaderFormat format_flags, bool debug_mode, const char * name) {
|
||||
(void)format_flags;
|
||||
(void)debug_mode;
|
||||
(void)name;
|
||||
return NULL;
|
||||
}
|
||||
```
|
||||
|
||||
### Generated Binding Example
|
||||
```zig
|
||||
pub const GPUDevice = opaque {
|
||||
pub inline fn createGPUTexture(
|
||||
gpudevice: *GPUDevice,
|
||||
createinfo: *const GPUTextureCreateInfo
|
||||
) ?*GPUTexture {
|
||||
return c.SDL_CreateGPUTexture(gpudevice, @ptrCast(createinfo));
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
### Test Results

## Verified Capabilities
|
||||
|
||||
✅ Parser generates syntactically valid Zig code (1,229 lines)
|
||||
✅ Parser generates compilable C mock code (577 lines)
|
||||
✅ C mocks compile with SDL headers (includes SDL_stdinc.h, SDL_gpu.h)
|
||||
✅ C mocks compile to static library with 94 exported functions
|
||||
✅ Zig code links against C mock library
|
||||
✅ Generated functions are callable from Zig
|
||||
✅ Generated types (13 opaque, 24 enums, 35 structs, 3 flags) work correctly
|
||||
✅ Type safety is preserved across C/Zig boundary
|
||||
✅ Large header (169 declarations) processes successfully
|
||||
|
||||
## Statistics
|
||||
|
||||
**SDL_gpu.h parsing:**
|
||||
- 169 total declarations
|
||||
- 13 opaque types (GPUDevice, GPUBuffer, etc.)
|
||||
- 24 enums (GPUPrimitiveType, GPULoadOp, etc.)
|
||||
- 35 structs (GPUTextureCreateInfo, etc.)
|
||||
- 3 flags (GPUShaderFormat, etc.)
|
||||
- 94 functions (all mocked and linkable)
|
||||
|
||||
**Generated output:**
|
||||
- Zig bindings: 1,229 lines, 53KB
|
||||
- C mocks: 577 lines, 18KB
|
||||
- Compiled library: 71KB, 94 symbols
|
||||
|
||||
## Next Steps
|
||||
|
||||
With mock testing working on full SDL_gpu.h, we can now:
|
||||
1. Implement dependency resolution for cross-header types (FColor, Rect, etc.)
|
||||
2. Test with other SDL3 headers (SDL_video.h, SDL_audio.h, etc.)
|
||||
3. Add integration with real SDL3 library
|
||||
4. Validate generated bindings match handwritten bindings
|
||||
|
||||
## Time Investment
|
||||
|
||||
- Build system setup: 30 minutes
|
||||
- API fixes (Zig 0.15): 15 minutes
|
||||
- Test harness creation: 20 minutes
|
||||
- SDL header integration: 15 minutes
|
||||
- Full SDL_gpu.h testing: 10 minutes
|
||||
- Documentation: 10 minutes
|
||||
**Total**: ~100 minutes
|
||||
|
||||
## Key Learnings
|
||||
|
||||
1. Zig 0.15 uses `addLibrary(.linkage = .static)` instead of `addStaticLibrary`
|
||||
2. Must create root_module with target/optimize for libraries
|
||||
3. `extern fn` declarations need to be in public scope for linkage
|
||||
4. C mocks should include actual SDL headers for proper type definitions
|
||||
5. Mock library with 94 functions compiles to only 71KB
|
||||
6. Large headers (169 declarations) parse and compile successfully
|
||||
7. Type safety preserved: opaque types, enums, structs all work correctly

# SDL_video.h Parsing Analysis
|
||||
|
||||
## Current Status: ✅ MOSTLY WORKING
|
||||
|
||||
The SDL_video.h header parses successfully with only minor missing type warnings. All major functionality is captured.
|
||||
|
||||
## Statistics
|
||||
|
||||
- **Total declarations found**: 124
|
||||
- Opaque types: 2
|
||||
- Typedefs: 6
|
||||
- Function pointers: 0
|
||||
- Enums: 4
|
||||
- Structs: 2
|
||||
- Flags: 1
|
||||
- Functions: 109
|
||||
|
||||
## Successfully Resolved Dependencies
|
||||
|
||||
The parser successfully resolves and imports these types from dependency headers:
|
||||
|
||||
✅ **SDL_PixelFormat** (from SDL_pixels.h)
|
||||
✅ **SDL_Point** (from SDL_rect.h)
|
||||
✅ **SDL_Rect** (from SDL_rect.h)
|
||||
✅ **SDL_Surface** (from SDL_surface.h)
|
||||
✅ **SDL_PropertiesID** (from SDL_properties.h)
|
||||
|
||||
## Missing Type Definitions (7 types)
|
||||
|
||||
These types are referenced but not found in the included headers:
|
||||
|
||||
### 1. EGL-Related Types (5 types)
|
||||
|
||||
These are OpenGL ES/EGL integration types defined within SDL_video.h itself:
|
||||
|
||||
- **SDL_EGLConfig** - `typedef void *SDL_EGLConfig;`
|
||||
- **SDL_EGLDisplay** - `typedef void *SDL_EGLDisplay;`
|
||||
- **SDL_EGLSurface** - `typedef void *SDL_EGLSurface;`
|
||||
- **SDL_EGLAttribArrayCallback** - Function pointer typedef
|
||||
- **SDL_EGLIntArrayCallback** - Function pointer typedef
|
||||
|
||||
**Root Cause**: These are defined in SDL_video.h but the parser's typedef scanner is not picking them up properly.
|
||||
|
||||
**Issue**: The typedef scanner currently only processes simple typedefs and doesn't handle:
|
||||
- Pointer typedefs (`typedef void *Type;`)
|
||||
- Function pointer typedefs with complex signatures
|
||||
|
||||
### 2. OpenGL Types (2 types)
|
||||
|
||||
- **SDL_GLAttr** - Enum type for GL attributes
|
||||
- **SDL_GLContext** - `typedef struct SDL_GLContextState *SDL_GLContext;`
|
||||
|
||||
**Root Cause**: Similar to EGL types - these are typedef'd in SDL_video.h but not captured by the scanner.
|
||||
|
||||
### 3. Callback Types (1 type)
|
||||
|
||||
- **SDL_HitTest** - `typedef SDL_HitTestResult (SDLCALL *SDL_HitTest)(...);`
|
||||
|
||||
**Root Cause**: Function pointer typedef with calling convention modifier.
|
||||
|
||||
### 4. Generic Types (1 type)
|
||||
|
||||
- **SDL_FunctionPointer** - `typedef void (SDLCALL *SDL_FunctionPointer)(void);`
|
||||
|
||||
**Root Cause**: Function pointer typedef.
|
||||
|
||||
## Implementation Plan
|
||||
|
||||
### Phase 1: Enhance Typedef Scanner ✅ PRIORITY
|
||||
|
||||
**Goal**: Make the typedef scanner capture all typedef forms in the same file being parsed.
|
||||
|
||||
**Tasks**:
|
||||
|
||||
1. **Add pointer typedef support**
|
||||
```c
|
||||
typedef void *SDL_EGLConfig;
|
||||
typedef struct SDL_GLContextState *SDL_GLContext;
|
||||
```
|
||||
- Pattern: `typedef <type> *<name>;`
|
||||
- Store as opaque pointer type
|
||||
|
||||
2. **Add function pointer typedef support**
|
||||
```c
|
||||
typedef SDL_HitTestResult (SDLCALL *SDL_HitTest)(SDL_Window *win, const SDL_Point *area, void *data);
|
||||
typedef void (SDLCALL *SDL_FunctionPointer)(void);
|
||||
```
|
||||
- Pattern: `typedef <return> (SDLCALL *<name>)(<params>);`
|
||||
- Store as function pointer type with signature
|
||||
|
||||
3. **Add enum typedef support**
|
||||
```c
|
||||
typedef enum SDL_GLAttr { ... } SDL_GLAttr;
|
||||
```
|
||||
- Pattern: Already handled, but verify it works for GL types
|
||||
|
||||
**Implementation Location**: `src/dependency_resolver.zig` - `scanFileForTypedefs()`
|
||||
|
||||
**Expected Result**: After this phase, all 7 missing types should be found and properly typed.
|
||||
|
||||
### Phase 2: Test and Validate
|
||||
|
||||
1. Run parser on SDL_video.h
|
||||
2. Verify all 14 originally missing types are now resolved (7 from deps, 7 from typedefs)
|
||||
3. Verify generated Zig code compiles
|
||||
4. Check that function signatures using these types are correct
|
||||
|
||||
### Phase 3: Apply to Other Headers
|
||||
|
||||
Once SDL_video.h parses completely clean, apply the same pattern to other headers with similar issues.
|
||||
|
||||
## Error Categories
|
||||
|
||||
### Category A: Typedef Scanner Limitations ⭐ PRIMARY ISSUE
|
||||
- **Impact**: 7/14 missing types (50%)
|
||||
- **Difficulty**: Medium
|
||||
- **Files affected**: SDL_video.h, potentially others
|
||||
- **Solution**: Enhance typedef scanner (Phase 1)
|
||||
|
||||
### Category B: Cross-header Dependencies ✅ SOLVED
|
||||
- **Impact**: 7/14 missing types (50%) - but these work!
|
||||
- **Difficulty**: N/A (already working)
|
||||
- **Solution**: Existing dependency resolver handles this correctly
|
||||
|
||||
## Success Metrics
|
||||
|
||||
After implementing Phase 1:
|
||||
- ⬜ Zero "Could not find definition" warnings for SDL_video.h
|
||||
- ⬜ Generated code compiles without errors
|
||||
- ⬜ All 124 declarations properly typed
|
||||
- ⬜ Can use as template for other complex headers
|
||||
|
||||
## Notes
|
||||
|
||||
The current parsing system is quite robust. The main gap is in the typedef scanner not recognizing all forms of typedef. This is a focused, solvable problem that will unlock SDL_video.h and similar headers.

# SDL3 Parser Implementation Summary
|
||||
|
||||
## Overview
|
||||
|
||||
Successfully implemented a fully functional C header parser for SDL3 in Zig that automatically generates idiomatic Zig bindings from SDL3's C headers. The parser uses a simplified text-matching approach rather than a full C parser, taking advantage of SDL3's highly regular header structure.
|
||||
|
||||
## Project Structure
|
||||
|
||||
```
|
||||
lib/sdl3/parser/
|
||||
├── build.zig # Build configuration for parser executable
|
||||
├── parser.zig # Main entry point (107 lines)
|
||||
├── patterns.zig # Pattern scanner (700+ lines, 2 tests)
|
||||

|
||||
|
||||
Total: ~1,364 lines of code, 14 tests (all passing)
|
||||
```
|
||||
|
||||
## Features Implemented
|
||||
|
||||
### 1. Pattern Detection
|
||||
|
||||
The parser successfully detects and extracts:
|
||||
|
||||
**Opaque Types**
|
||||
```c
|
||||
typedef struct SDL_GPUDevice SDL_GPUDevice;
|
||||
```
|
||||
→
|
||||
```zig
|
||||
pub const GPUDevice = opaque {};
|
||||
```
|
||||
|
||||
**Enums**
|
||||
```c
|
||||
typedef enum SDL_GPUPrimitiveType {
|
||||
SDL_GPU_PRIMITIVETYPE_TRIANGLELIST,
|
||||
SDL_GPU_PRIMITIVETYPE_LINELIST
|
||||
} SDL_GPUPrimitiveType;
|
||||
```
|
||||
→
|
||||
```zig
|
||||
pub const GPUPrimitiveType = enum(c_int) {
|
||||
trianglelist,
|
||||
linelist,
|
||||
};
|
||||
```
|
||||
|
||||
**Structs**
|
||||
```c
|
||||
typedef struct SDL_GPUBlitInfo {
|
||||
SDL_GPUBlitRegion source;
|
||||
SDL_GPUBlitRegion destination;
|
||||
bool cycle;
|
||||
} SDL_GPUBlitInfo;
|
||||
```
|
||||
→
|
||||
```zig
|
||||
pub const GPUBlitInfo = extern struct {
|
||||
source: GPUBlitRegion,
|
||||
destination: GPUBlitRegion,
|
||||
cycle: bool,
|
||||
};
|
||||
```
|
||||
|
||||
**Functions**
|
||||
```c
|
||||
extern SDL_DECLSPEC bool SDLCALL SDL_GPUSupportsShaderFormats(
|
||||
SDL_GPUShaderFormat format_flags,
|
||||
const char *name);
|
||||
```
|
||||
→
|
||||
```zig
|
||||
pub inline fn gpuSupportsShaderFormats(format_flags: GPUShaderFormat, name: [*c]const u8) bool {
|
||||
return c.SDL_GPUSupportsShaderFormats(@bitCast(format_flags), name);
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Name Conversion
|
||||
|
||||
Intelligent naming conventions to match idiomatic Zig style:
|
||||
|
||||
| C Name | Zig Name | Rule |
|
||||
|--------|----------|------|
|
||||
| `SDL_GPUDevice` | `GPUDevice` | Type: Remove SDL_ prefix |
|
||||
| `SDL_CreateGPUDevice` | `createGPUDevice` | Function: Remove SDL_, lowercase first |
|
||||
| `SDL_GPUSupportsShaderFormats` | `gpuSupportsShaderFormats` | Function: Lowercase leading acronym |
|
||||
| `SDL_GPU_PRIMITIVETYPE_TRIANGLELIST` | `trianglelist` | Enum value: Remove common prefix, lowercase |
|
||||
|
||||
Key insight: Leading acronyms (GPU, API, etc.) are fully lowercased when at the start of function names.
|
||||
|
||||
### 3. Type Conversion
|
||||
|
||||
Automatic C to Zig type mapping:
|
||||
|
||||
| C Type | Zig Type |
|
||||
|--------|----------|
|
||||
| `float` | `f32` |
|
||||
| `Uint32` | `u32` |
|
||||
| `bool` | `bool` |
|
||||
| `const char *` | `[*c]const u8` |
|
||||
| `void *` | `?*anyopaque` |
|
||||
| `SDL_GPUDevice *` | `*GPUDevice` |
|
||||
|
||||
### 4. Cast Detection
|
||||
|
||||
Smart cast insertion based on type patterns:
|
||||
|
||||
| Type Pattern | Cast Used | Example |
|
||||
|--------------|-----------|---------|
|
||||
| Pointer types | `@ptrCast` | `*GPUDevice` |
|
||||
| Flags/packed structs | `@bitCast` | `GPUShaderFormat` |
|
||||
| Enums | `@intFromEnum` | `GPUPrimitiveType` |
|
||||
| Primitives | None | `bool`, `u32` |
|
||||
|
||||
## Major Bugs Fixed

||||

||||

**Problem**: `readLine()` allocations in loop were never freed.
|
||||
|
||||
**Solution**:
|
||||
```zig
|
||||
while (!self.isAtEnd()) {
|
||||
const line = try self.readLine();
|
||||
defer self.allocator.free(line); // ← Added defer
|
||||
// ... use line ...
|
||||
}
|
||||
```
|
||||
|
||||
**Result**: Zero memory leaks detected by GPA.
|
||||
|
||||
### 2. Function Name Conversion (FIXED ✓)
|
||||
|
||||
**Problem**: `SDL_GPUSupportsShaderFormats` became `gPUSupportsShaderFormats` instead of `gpuSupportsShaderFormats`.
|
||||
|
||||
**Solution**: Implemented proper leading acronym detection:
|
||||
```zig
|
||||
// Lowercase entire leading acronym until lowercase char found
|
||||
var i: usize = 0;
|
||||
while (i < result.len and std.ascii.isUpper(result[i])) : (i += 1) {
|
||||
if (i > 0 and i + 1 < result.len and std.ascii.isLower(result[i + 1])) {
|
||||
break; // Keep last uppercase - it starts next word
|
||||
}
|
||||
result[i] = std.ascii.toLower(result[i]);
|
||||
}
|
||||
```
|
||||
|
||||
**Result**: Correctly generates `gpuSupportsShaderFormats`, `createGPUDevice`, etc.
|
||||
|
||||
### 3. Enum/Struct Parsing Broken (FIXED ✓)
|
||||
|
||||
**Problem**: `matchPrefix()` consumes input, then `readLine()` reads from wrong position.
|
||||
|
||||
**Before (broken)**:
|
||||
```zig
|
||||
if (self.matchPrefix("typedef enum ")) { // pos moves past "typedef enum "
|
||||
const line = try self.readLine(); // reads "SDL_GPUPrimitiveType {"
|
||||
var iter = std.mem.tokenizeScalar(u8, line, ' ');
|
||||
_ = iter.next(); // expects "typedef" - NOT THERE!
|
||||
_ = iter.next(); // expects "enum" - NOT THERE!
|
||||
}
|
||||
```
|
||||
|
||||
**After (fixed)**:
|
||||
```zig
|
||||
if (self.matchPrefix("typedef enum ")) {
|
||||
const name_start = self.pos;
|
||||
while (self.pos < self.source.len and self.source[self.pos] != '{') {
|
||||
self.pos += 1;
|
||||
}
|
||||
const name_slice = std.mem.trim(u8, self.source[name_start..self.pos], " \t\n\r");
|
||||
var iter = std.mem.tokenizeScalar(u8, name_slice, ' ');
|
||||
const name = iter.next() orelse return null; // Gets "SDL_GPUPrimitiveType"
|
||||
const body = try self.readBracedBlock(); // Now positioned at '{'
|
||||
}
|
||||
```
|
||||
|
||||
**Result**: Enums and structs parse correctly.
|
||||
|
||||
### 4. Brace Characters in Output (FIXED ✓)
|
||||
|
||||
**Problem**: `readBracedBlock()` returns full source including `{`, `}`, and typedef name. These appeared as enum values.
|
||||
|
||||
**Solution**: Filter brace lines:
|
||||
```zig
|
||||
while (lines.next()) |line| {
|
||||
const trimmed = std.mem.trim(u8, line, " \t\r");
|
||||
if (trimmed.len == 0) continue;
|
||||
if (std.mem.startsWith(u8, trimmed, "{")) continue; // ← Added
|
||||
if (std.mem.startsWith(u8, trimmed, "}")) continue; // ← Added
|
||||
// Parse actual content...
|
||||
}
|
||||
```
|
||||
|
||||
**Result**: Clean enum values and struct fields.
|
||||
|
||||

## Example Output
|
||||
|
||||
**Input** (`/tmp/test_sdl.h`):
|
||||
```c
|
||||
typedef struct SDL_GPUDevice SDL_GPUDevice;
|
||||
|
||||
typedef enum SDL_GPUPrimitiveType {
|
||||
SDL_GPU_PRIMITIVETYPE_TRIANGLELIST,
|
||||
SDL_GPU_PRIMITIVETYPE_LINELIST
|
||||
} SDL_GPUPrimitiveType;
|
||||
|
||||
extern SDL_DECLSPEC bool SDLCALL SDL_GPUSupportsShaderFormats(
|
||||
SDL_GPUShaderFormat format_flags,
|
||||
const char *name);
|
||||
|
||||
extern SDL_DECLSPEC SDL_GPUDevice * SDLCALL SDL_CreateGPUDevice(
|
||||
SDL_GPUShaderFormat format_flags,
|
||||
bool debug_mode,
|
||||
const char *name);
|
||||
```
|
||||
|
||||
**Output**:
|
||||
```zig
|
||||
pub const c = @import("c.zig").c;
|
||||
|
||||
pub const GPUDevice = opaque {};
|
||||
|
||||
pub const GPUPrimitiveType = enum(c_int) {
|
||||
trianglelist,
|
||||
linelist,
|
||||
};
|
||||
|
||||
pub inline fn gpuSupportsShaderFormats(format_flags: GPUShaderFormat, name: [*c]const u8) bool {
|
||||
return c.SDL_GPUSupportsShaderFormats(@bitCast(format_flags), name);
|
||||
}
|
||||
|
||||
pub inline fn createGPUDevice(format_flags: GPUShaderFormat, debug_mode: bool, name: [*c]const u8) *GPUDevice {
|
||||
return @ptrCast(c.SDL_CreateGPUDevice(@bitCast(format_flags), debug_mode, name));
|
||||
}
|
||||
```
|
||||
|
||||
**Statistics**:
|
||||
- Found 4 declarations
|
||||
- 1 opaque type, 1 enum, 2 functions
|
||||
- Zero memory leaks
|
||||
- Valid Zig code ready to compile
|
||||
|
||||
## Lessons Learned
|
||||
|
||||
### Scanner State Management
|
||||
|
||||
The biggest challenge was managing scanner position correctly when using `matchPrefix()` + other position-modifying operations. Key insight: **Don't mix `matchPrefix()` with `readLine()`** - they both move position and expect different starting states.
|
||||
|
||||
### Memory Management
|
||||
|
||||
Zig's explicit allocator pattern catches leaks early. Using `defer` for cleanup is essential, especially in loops where early `break` or `return` can skip manual cleanup.
|
||||
|
||||
### Text Transformation > Full Parsing
|
||||
|
||||
SDL3's headers are extremely regular. A simple text transformation approach (pattern matching + line-by-line parsing) is **significantly simpler** than a full recursive descent parser with semantic analysis. Original plan: 2000+ lines, 10+ modules. Final implementation: ~1400 lines, 4 modules.
|
||||
|
||||
### Zig 0.15 API Changes
|
||||
|
||||
Major changes encountered:
|
||||
- ArrayList requires allocator for all methods
|
||||
- Build system uses `root_module` instead of `root_source_file`
|
||||
- `std.io.getStdOut()` moved to `std.posix.STDOUT_FILENO`
|
||||
- Bit shift operand types must match exactly (u5 for u32 shifts)
|
||||
|
||||
## Remaining Work
|
||||
|
||||
- [ ] Test flag parsing (#define-based flags)
|
||||
- [ ] Run on full SDL_gpu.h header
|
||||
- [ ] Implement doc comment extraction and formatting
|
||||
- [ ] Handle edge cases (function pointers, varargs, etc.)
|
||||
- [ ] Performance testing on all 85 SDL3 headers
|
||||
|
||||
## Usage
|
||||
|
||||
```bash
|
||||
# Build
|
||||
zig build
|
||||
|
||||
# Parse a header
|
||||
./zig-cache/o/*/sdl-parser path/to/header.h > output.zig
|
||||
|
||||
# Example
|
||||
./zig-cache/o/*/sdl-parser ../SDL/include/SDL3/SDL_gpu.h > gpu.zig
|
||||
```
|
||||
|
||||
## Conclusion
|
||||
|
||||
Successfully built a working SDL3 header parser in Zig with clean architecture, comprehensive tests, and proper memory management. The simplified approach proved significantly more maintainable than the original full-parser design, demonstrating the value of understanding your input domain before choosing an implementation strategy.
