docs: Add comprehensive documentation for getting started, testing, building, and architecture
- Introduced a new "Getting Started" guide to help users set up and use the YAZE software effectively. - Added detailed "Testing Guide" outlining the testing framework and best practices for contributors. - Created "Build Instructions" for macOS, Linux, and Windows, including environment verification and quick start with CMake presets. - Documented the architecture and networking aspects of YAZE, focusing on service-oriented design and gRPC integration. - Updated the index to reflect new documentation structure and improve navigation.

|
||||
## 🎊 Summary
|
||||
|
||||

|
||||
## 🏗️ Architecture
|
||||
|
||||
### **YazeGRPCServer** (formerly UnifiedGRPCServer)
|
||||
|
||||
```cpp
|
||||
class YazeGRPCServer {
|
||||
public:
|
||||
struct Config {
|
||||
int port = 50051;
|
||||
bool enable_test_harness = true;
|
||||
bool enable_rom_service = true;
|
||||
bool enable_canvas_automation = true; // NEW!
|
||||
bool require_approval_for_rom_writes = true;
|
||||
};
|
||||
|
||||
absl::Status Initialize(
|
||||
int port,
|
||||
test::TestManager* test_manager = nullptr,
|
||||
app::Rom* rom = nullptr,
|
||||
app::net::RomVersionManager* version_mgr = nullptr,
|
||||
app::net::ProposalApprovalManager* approval_mgr = nullptr,
|
||||
CanvasAutomationServiceImpl* canvas_service = nullptr); // NEW!
|
||||
};
|
||||
```
|
||||
|
||||
### **Service Stack**
|
||||
|
||||
```
|
||||
YazeGRPCServer (Port 50051)
|
||||
├── ImGuiTestHarness [GUI automation]
|
||||
├── RomService [ROM manipulation]
|
||||
└── CanvasAutomation [Canvas operations] ✅ NEW
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🔧 Technical Details
|
||||
|
||||
### **Incomplete Type Solution**
|
||||
|
||||
**Problem**: `unique_ptr<CanvasAutomationServiceGrpc>` caused incomplete type errors
|
||||
|
||||
**Solution**:
|
||||
1. Store as `unique_ptr<grpc::Service>` (base class)
|
||||
2. Factory function returns `grpc::Service*`
|
||||
3. Destructor defined in .cc file
|
||||
4. Proto includes only in .cc file
|
||||
|
||||
```cpp
|
||||
// Header: Store as base class
|
||||
std::unique_ptr<grpc::Service> canvas_grpc_service_;
|
||||
|
||||
// Implementation: Factory returns base class
|
||||
std::unique_ptr<grpc::Service> CreateCanvasAutomationServiceGrpc(
|
||||
CanvasAutomationServiceImpl* impl) {
|
||||
return std::make_unique<CanvasAutomationServiceGrpc>(impl);
|
||||
}
|
||||
```
|
||||
|
||||
### **Service Wrapper Pattern**
|
||||
|
||||
```cpp
|
||||
class CanvasAutomationServiceGrpc final : public proto::CanvasAutomation::Service {
|
||||
public:
|
||||
explicit CanvasAutomationServiceGrpc(CanvasAutomationServiceImpl* impl)
|
||||
: impl_(impl) {}
|
||||
|
||||
grpc::Status SetTile(...) override {
|
||||
return ConvertStatus(impl_->SetTile(request, response));
|
||||
}
|
||||
|
||||
// ... 13 more RPC methods ...
|
||||
|
||||
private:
|
||||
CanvasAutomationServiceImpl* impl_;
|
||||
};
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 🎯 What's Ready to Test
|
||||
|
||||
### **✅ Working Right Now** (No Build Needed)
|
||||
|
||||
CLI commands work immediately:
|
||||
```bash
|
||||
cd /Users/scawful/Code/yaze
|
||||
|
||||
# Test selection
|
||||
./build/bin/z3ed overworld select-rect --map 0 --x1 5 --y1 5 --x2 10 --y2 10 --rom assets/zelda3.sfc
|
||||
|
||||
# Test scroll
|
||||
./build/bin/z3ed overworld scroll-to --map 0 --x 10 --y 10 --center --rom assets/zelda3.sfc
|
||||
|
||||
# Test zoom
|
||||
./build/bin/z3ed overworld set-zoom --zoom 1.5 --rom assets/zelda3.sfc
|
||||
|
||||
# Test visible region
|
||||
./build/bin/z3ed overworld get-visible-region --map 0 --format json --rom assets/zelda3.sfc
|
||||
```
|
||||
|
||||
### **⏳ After Full Build** (Pending assembly_editor fix)
|
||||
|
||||
1. **GUI with gRPC**:
|
||||
```bash
|
||||
./build/bin/yaze --grpc-port 50051 assets/zelda3.sfc
|
||||
```
|
||||
|
||||
2. **gRPC Service Testing**:
|
||||
```bash
|
||||
# List services
|
||||
grpcurl -plaintext localhost:50051 list
|
||||
|
||||
# Test Canvas Automation
|
||||
grpcurl -plaintext -d '{"canvas_id":"OverworldCanvas"}' \
|
||||
localhost:50051 yaze.proto.CanvasAutomation/GetDimensions
|
||||
|
||||
# Set tile
|
||||
grpcurl -plaintext -d '{"canvas_id":"OverworldCanvas","x":10,"y":10,"tile_id":42}' \
|
||||
localhost:50051 yaze.proto.CanvasAutomation/SetTile
|
||||
```
|
||||
|
||||
3. **Unit Tests**:
|
||||
```bash
|
||||
./build/bin/yaze_test --gtest_filter="CanvasAutomationAPI*"
|
||||
./build/bin/yaze_test --gtest_filter="TileSelectorWidget*"
|
||||
```

## 🚀 Usage Examples
|
||||
|
||||
### **C++ Application Initialization**
|
||||
|
||||
```cpp
|
||||
// Create canvas automation service
|
||||
auto canvas_service = std::make_unique<CanvasAutomationServiceImpl>();
|
||||
|
||||
// Register overworld editor's canvas
|
||||
canvas_service->RegisterCanvas("OverworldCanvas",
|
||||
overworld_editor->GetOverworldCanvas());
|
||||
canvas_service->RegisterOverworldEditor("OverworldCanvas",
|
||||
overworld_editor);
|
||||
|
||||
// Start YAZE gRPC server
|
||||
YazeGRPCServer grpc_server;
|
||||
grpc_server.Initialize(50051, test_manager, rom, version_mgr, approval_mgr,
|
||||
canvas_service.get());
|
||||
grpc_server.StartAsync(); // Non-blocking
|
||||
|
||||
// ... run your app ...
|
||||
|
||||
grpc_server.Shutdown();
|
||||
```
|
||||
|
||||
### **Python Client Example**
|
||||
|
||||
```python
|
||||
import grpc
|
||||
from protos import canvas_automation_pb2_grpc, canvas_automation_pb2
|
||||
|
||||
# Connect to YAZE
|
||||
channel = grpc.insecure_channel('localhost:50051')
|
||||
stub = canvas_automation_pb2_grpc.CanvasAutomationStub(channel)
|
||||
|
||||
# Get dimensions
|
||||
response = stub.GetDimensions(
|
||||
canvas_automation_pb2.GetDimensionsRequest(
|
||||
canvas_id="OverworldCanvas"
|
||||
)
|
||||
)
|
||||
print(f"Canvas: {response.dimensions.width_tiles}x{response.dimensions.height_tiles}")
|
||||
|
||||
# Set zoom
|
||||
stub.SetZoom(canvas_automation_pb2.SetZoomRequest(
|
||||
canvas_id="OverworldCanvas",
|
||||
zoom=1.5
|
||||
))
|
||||
|
||||
# Paint tiles
|
||||
stub.SetTile(canvas_automation_pb2.SetTileRequest(
|
||||
canvas_id="OverworldCanvas",
|
||||
x=10, y=10, tile_id=42
|
||||
))
