# Widget ID Refactoring - Next Actions

**Date**: October 2, 2025  
**Status**: Phase 1 Complete - Testing & Integration Phase  
**Previous Session**: [SESSION_SUMMARY_OCT2_NIGHT.md](SESSION_SUMMARY_OCT2_NIGHT.md)

## Quick Start - Next Session

### Option 1: Manual Testing (15 minutes) 🎯 RECOMMENDED FIRST

**Goal**: Verify widgets register correctly in running GUI

```bash
# 1. Launch YAZE
./build/bin/yaze.app/Contents/MacOS/yaze

# 2. Open a ROM
# File → Open ROM → assets/zelda3.sfc

# 3. Open Overworld Editor
# Click "Overworld" button in main window

# 4. Test toolset buttons
# Click through: Pan, DrawTile, Entrances, etc.
# Expected: All work normally, no crashes

# 5. Check console output
# Look for any errors or warnings
# Widget registrations happen silently
```

**Success Criteria**:
- ✅ GUI launches without crashes
- ✅ Overworld editor opens normally
- ✅ All toolset buttons clickable
- ✅ No error messages in console

---

### Option 2: Add Widget Discovery Command (30 minutes)

**Goal**: Create CLI command to list registered widgets

**File to Edit**: `src/cli/handlers/agent.cc`

**Add New Command**: `z3ed agent discover`

```cpp
// Add to agent.cc:
absl::Status HandleDiscoverCommand(const std::vector<std::string>& args) {
  // Parse --pattern flag (default "*")
  std::string pattern = "*";
  for (size_t i = 0; i < args.size(); ++i) {
    if (args[i] == "--pattern" && i + 1 < args.size()) {
      pattern = args[++i];
    }
  }
  
  // Get widget registry
  auto& registry = gui::WidgetIdRegistry::Instance();
  auto matches = registry.FindWidgets(pattern);
  
  if (matches.empty()) {
    std::cout << "No widgets found matching pattern: " << pattern << "\n";
    return absl::NotFoundError("No widgets found");
  }
  
  std::cout << "=== Registered Widgets ===\n\n";
  std::cout << "Pattern: " << pattern << "\n";
  std::cout << "Count: " << matches.size() << "\n\n";
  
  for (const auto& path : matches) {
    const auto* info = registry.GetWidgetInfo(path);
    if (info) {
      std::cout << path << "\n";
      std::cout << "  Type: " << info->type << "\n";
      std::cout << "  ImGui ID: " << info->imgui_id << "\n";
      if (!info->description.empty()) {
        std::cout << "  Description: " << info->description << "\n";
      }
      std::cout << "\n";
    }
  }
  
  return absl::OkStatus();
}

// Add routing in HandleAgentCommand:
if (subcommand == "discover") {
  return HandleDiscoverCommand(args);
}
```

**Test**:
```bash
# Rebuild
cmake --build build --target z3ed -j8

# Test discovery (will fail - widgets registered at runtime)
./build/bin/z3ed agent discover
# Note: This requires YAZE to be running with widgets registered
# We'll need a different approach - see Option 3
```

---

### Option 3: Widget Export at Shutdown (30 minutes) 🎯 BETTER APPROACH

**Goal**: Export widget catalog when YAZE exits

**File to Edit**: `src/app/editor/editor_manager.cc`

**Add Destructor or Shutdown Method**:

```cpp
// In editor_manager.cc destructor or Shutdown():
void EditorManager::Shutdown() {
  // Export widget catalog for z3ed agent
  auto& registry = gui::WidgetIdRegistry::Instance();
  std::string catalog_path = "/tmp/yaze_widgets.yaml";
  
  try {
    registry.ExportCatalogToFile(catalog_path, "yaml");
    std::cout << "Widget catalog exported to: " << catalog_path << "\n";
  } catch (const std::exception& e) {
    std::cerr << "Failed to export widget catalog: " << e.what() << "\n";
  }
}
```

**Test**:
```bash
# 1. Rebuild
cmake --build build --target yaze -j8

# 2. Launch YAZE
./build/bin/yaze.app/Contents/MacOS/yaze

# 3. Open Overworld editor
# (registers widgets)

# 4. Quit YAZE
# File → Quit or Cmd+Q

# 5. Check exported catalog
cat /tmp/yaze_widgets.yaml

# Expected output:
# widgets:
#   - path: "Overworld/Toolset/button:Pan"
#     type: button
#     imgui_id: 12345
#     context:
#       editor: Overworld
#       tab: Toolset
#     ...
```

### Option 4: Test Harness Integration (1-2 hours)

**Goal**: Enable test harness to click widgets by hierarchical ID

**Files to Edit**:
1. `src/app/core/service/imgui_test_harness_service.cc`
2. `src/app/core/proto/imgui_test_harness.proto` (optional - add DiscoverWidgets RPC)

**Implementation**:

```cpp
// In imgui_test_harness_service.cc, update Click RPC:
absl::Status ImGuiTestHarnessServiceImpl::Click(
    const ClickRequest* request, ClickResponse* response) {
  
  const std::string& target = request->target();
  
  // Try hierarchical widget ID first
  auto& registry = gui::WidgetIdRegistry::Instance();
  ImGuiID widget_id = registry.GetWidgetId(target);
  
  if (widget_id != 0) {
    // Found in registry - use ImGui ID directly
    std::string test_name = absl::StrFormat("DynamicClick_%s", target);
    
    auto* dynamic_test = ImGuiTest_CreateDynamicTest(
        test_manager_->GetEngine(), test_category_.c_str(), test_name.c_str());
    
    dynamic_test->GuiFunc = [widget_id](ImGuiTestContext* ctx) {
      ctx->ItemClick(widget_id);
    };
    
    ImGuiTest_RunTest(test_manager_->GetEngine(), dynamic_test);
    
    response->set_success(true);
    response->set_message(absl::StrFormat("Clicked widget: %s", target));
    return absl::OkStatus();
  }
  
  // Fallback to legacy string-based lookup
  // ... existing code ...
  
  // If not found, suggest alternatives
  auto matches = registry.FindWidgets("*" + target + "*");
  if (!matches.empty()) {
    std::string suggestions = absl::StrJoin(matches, ", ");
    return absl::NotFoundError(
        absl::StrFormat("Widget not found: %s. Did you mean: %s?",
                        target, suggestions));
  }
  
  return absl::NotFoundError(
      absl::StrFormat("Widget not found: %s", target));
}
```

**Test**:
```bash
# 1. Rebuild with gRPC
cmake --build build-grpc-test --target yaze -j8

# 2. Start test harness
./build-grpc-test/bin/yaze.app/Contents/MacOS/yaze \
  --enable_test_harness \
  --test_harness_port=50052 \
  --rom_file=assets/zelda3.sfc &

# 3. Open Overworld editor in GUI
# (registers widgets)

# 4. Test hierarchical click
grpcurl -plaintext \
  -import-path src/app/core/proto \
  -proto imgui_test_harness.proto \
  -d '{"target":"Overworld/Toolset/button:DrawTile","type":"LEFT"}' \
  127.0.0.1:50052 yaze.test.ImGuiTestHarness/Click

# Expected: Click succeeds, DrawTile mode activated
```
