# ImGui ID Management Refactoring Plan
|
||||
|
||||
**Date**: October 2, 2025
|
||||
**Goal**: Improve GUI ID management for better test automation and eliminate duplicate ID issues
|
||||
**Related**: z3ed CLI test automation, ImGuiTestHarness integration
|
||||
|
||||
## Executive Summary
|
||||
|
||||
The current YAZE codebase uses ImGui's `##` prefix for hidden labels extensively (100+ occurrences), which creates challenges for automated testing and can lead to ID conflicts when widgets share the same label within the same ID scope.
|
||||
|
||||
**Key Problems**:
|
||||
1. **Difficult to reference widgets** - Test automation needs stable, predictable widget IDs
|
||||
2. **Potential ID conflicts** - Multiple `##table` or `##canvas` widgets in same scope
|
||||
3. **Inconsistent naming** - No convention for widget naming across editors
|
||||
4. **No centralized registry** - Hard to discover available widget IDs for testing
|
||||
|
||||
**Proposed Solution**:
|
||||
- Implement hierarchical ID scheme with scoping
|
||||
- Create centralized widget ID registry
|
||||
- Add systematic `PushID`/`PopID` usage
|
||||
- Establish naming conventions
|
||||
- Build tooling for ID discovery and validation
|
||||
|
||||
## Current State Analysis
|
||||
|
||||
### Pattern 1: Unnamed Widgets with ## Prefix (Most Common)
|
||||
|
||||
Found 100+ instances across the codebase:
|
||||
|
||||
```cpp
|
||||
// overworld_editor.cc
|
||||
if (BeginTable("##BlocksetTable", ...)) { }
|
||||
if (BeginChild("##RoomsetList")) { }
|
||||
InputText("##CGXFile", &cgx_file_name_);
|
||||
|
||||
// dungeon_editor.cc
|
||||
gui::InputHexByte("##layout", &room.layout);
|
||||
gui::InputHexByte("##blockset", &room.blockset);
|
||||
|
||||
// palette_editor.cc
|
||||
ColorPicker4("##picker", (float*)&color, ...);
|
||||
ColorButton("##palette", current_palette[n], ...);
|
||||
```
|
||||
|
||||
**Problem**: Multiple widgets named `##table`, `##canvas`, `##picker` etc. across different editors can conflict when windows overlap or use shared ID stacks.
|
||||
|
||||
### Pattern 2: Dynamic IDs with String Formatting
|
||||
|
||||
```cpp
|
||||
// graphics_editor.cc
|
||||
ImGui::BeginChild(absl::StrFormat("##GfxSheet%02X", key).c_str(), ...);
|
||||
ImGui::Begin(absl::StrFormat("##GfxEditPaletteChildWindow%d", id).c_str(), ...);
|
||||
|
||||
// tile16_editor.cc
|
||||
ImGui::ColorButton(absl::StrFormat("##c%d", i).c_str(), ...);
|
||||
```
|
||||
|
||||
**Good**: Unique IDs, but still hard to reference from test automation without knowing the exact format string.
|
||||
|
||||
### Pattern 3: Explicit PushID/PopID (Rare)
|
||||
|
||||
Only found in third-party ImGuiTestEngine code, rarely used in YAZE:
|
||||
|
||||
```cpp
|
||||
// imgui_test_engine (example of good practice)
|
||||
ImGui::PushID(window);
|
||||
// ... widgets here ...
|
||||
ImGui::PopID();
|
||||
```
|
||||
|
||||
**Missing**: YAZE editors don't systematically use ID scoping.
|
||||
|
||||
## Proposed Hierarchical ID Scheme
|
||||
|
||||
### Design Principles
|
||||
|
||||
1. **Hierarchical Naming**: Editor → Tab → Section → Widget
|
||||
2. **Stable IDs**: Don't change across frames or code refactors
|
||||
3. **Discoverable**: Can be enumerated for test automation
|
||||
4. **Backwards Compatible**: Gradual migration, no breaking changes
|
||||
|
||||
### ID Format Convention
|
||||
|
||||
```
|
||||
<Editor>/<Tab>/<Section>/<WidgetType>:<Name>
|
||||
```
|
||||
|
||||
**Examples**:
|
||||
```
|
||||
Overworld/Main/Toolset/button:DrawTile
|
||||
Overworld/Main/Canvas/canvas:OverworldMap
|
||||
Overworld/MapSettings/Table/input:AreaGfx
|
||||
Dungeon/Room/Properties/input:Layout
|
||||
Palette/Main/Picker/button:Color0
|
||||
Graphics/Sheets/Sheet0x00/canvas:Tiles
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- **Unique**: Hierarchical structure prevents conflicts
|
||||
- **Readable**: Clear what editor and context each widget belongs to
|
||||
- **Testable**: Test harness can reference by full path or partial match
|
||||
- **Discoverable**: Can build tree of all available widget IDs
|
||||
|
||||
### Implementation Strategy
|
||||
|
||||
#### Phase 1: Core Infrastructure (2-3 hours)
|
||||
|
||||
**Create Widget ID Registry System**:
|
||||
|
||||
```cpp
|
||||
// src/app/gui/widget_id_registry.h
|
||||
namespace yaze::gui {
|
||||
|
||||
class WidgetIdScope {
|
||||
public:
|
||||
explicit WidgetIdScope(const std::string& name);
|
||||
~WidgetIdScope(); // Auto PopID()
|
||||
|
||||
std::string GetFullPath() const;
|
||||
|
||||
private:
|
||||
std::string name_;
|
||||
static std::vector<std::string> id_stack_;
|
||||
};
|
||||
|
||||
class WidgetIdRegistry {
|
||||
public:
|
||||
static WidgetIdRegistry& Instance();
|
||||
|
||||
// Register a widget for discovery
|
||||
void RegisterWidget(const std::string& full_path,
|
||||
const std::string& type,
|
||||
ImGuiID imgui_id);
|
||||
|
||||
// Query widgets for test automation
|
||||
std::vector<std::string> FindWidgets(const std::string& pattern) const;
|
||||
ImGuiID GetWidgetId(const std::string& full_path) const;
|
||||
|
||||
// Export catalog for z3ed agent describe
|
||||
void ExportCatalog(const std::string& output_file) const;
|
||||
|
||||
private:
|
||||
struct WidgetInfo {
|
||||
std::string full_path;
|
||||
std::string type;
|
||||
ImGuiID imgui_id;
|
||||
};
|
||||
std::unordered_map<std::string, WidgetInfo> widgets_;
|
||||
};
|
||||
|
||||
// RAII helper macros
|
||||
#define YAZE_WIDGET_SCOPE(name) \
|
||||
yaze::gui::WidgetIdScope _scope##__LINE__(name)
|
||||
|
||||
#define YAZE_REGISTER_WIDGET(type, name) \
|
||||
yaze::gui::WidgetIdRegistry::Instance().RegisterWidget( \
|
||||
_scope##__LINE__.GetFullPath() + "/" #type ":" name, \
|
||||
#type, \
|
||||
ImGui::GetItemID())
|
||||
|
||||
} // namespace yaze::gui
|
||||
```
|
||||
|
||||
**Implementation**:
|
||||
|
||||
```cpp
|
||||
// src/app/gui/widget_id_registry.cc
|
||||
namespace yaze::gui {
|
||||
|
||||
thread_local std::vector<std::string> WidgetIdScope::id_stack_;
|
||||
|
||||
WidgetIdScope::WidgetIdScope(const std::string& name) : name_(name) {
|
||||
ImGui::PushID(name.c_str());
|
||||
id_stack_.push_back(name);
|
||||
}
|
||||
|
||||
WidgetIdScope::~WidgetIdScope() {
|
||||
ImGui::PopID();
|
||||
if (!id_stack_.empty()) {
|
||||
id_stack_.pop_back();
|
||||
}
|
||||
}
|
||||
|
||||
std::string WidgetIdScope::GetFullPath() const {
|
||||
std::string path;
|
||||
for (const auto& segment : id_stack_) {
|
||||
if (!path.empty()) path += "/";
|
||||
path += segment;
|
||||
}
|
||||
return path;
|
||||
}
|
||||
|
||||
void WidgetIdRegistry::RegisterWidget(const std::string& full_path,
|
||||
const std::string& type,
|
||||
ImGuiID imgui_id) {
|
||||
WidgetInfo info{full_path, type, imgui_id};
|
||||
widgets_[full_path] = info;
|
||||
}
|
||||
|
||||
std::vector<std::string> WidgetIdRegistry::FindWidgets(
|
||||
const std::string& pattern) const {
|
||||
std::vector<std::string> matches;
|
||||
for (const auto& [path, info] : widgets_) {
|
||||
if (path.find(pattern) != std::string::npos) {
|
||||
matches.push_back(path);
|
||||
}
|
||||
}
|
||||
return matches;
|
||||
}
|
||||
|
||||
} // namespace yaze::gui
|
||||
```
|
||||
|
||||
#### Phase 2: Refactor Overworld Editor (3-4 hours)
|
||||
|
||||
**Before** (overworld_editor.cc):
|
||||
```cpp
|
||||
void OverworldEditor::DrawToolset() {
|
||||
gui::DrawTable(toolset_table_);
|
||||
|
||||
if (show_tile16_editor_) {
|
||||
if (ImGui::Begin("Tile16 Editor", &show_tile16_editor_)) {
|
||||
tile16_editor_.Update();
|
||||
}
|
||||
ImGui::End();
|
||||
}
|
||||
}
|
||||
|
||||
void OverworldEditor::DrawOverworldCanvas() {
|
||||
if (ImGui::BeginChild("##OverworldCanvas", ImVec2(0, 0), true)) {
|
||||
// Canvas rendering...
|
||||
}
|
||||
ImGui::EndChild();
|
||||
}
|
||||
```
|
||||
|
||||
**After**:
|
||||
```cpp
|
||||
void OverworldEditor::DrawToolset() {
|
||||
YAZE_WIDGET_SCOPE("Toolset");
|
||||
|
||||
gui::DrawTable(toolset_table_);
|
||||
|
||||
if (show_tile16_editor_) {
|
||||
YAZE_WIDGET_SCOPE("Tile16Editor");
|
||||
if (ImGui::Begin("Tile16 Editor", &show_tile16_editor_)) {
|
||||
tile16_editor_.Update();
|
||||
}
|
||||
ImGui::End();
|
||||
}
|
||||
}
|
||||
|
||||
void OverworldEditor::DrawOverworldCanvas() {
|
||||
YAZE_WIDGET_SCOPE("Canvas");
|
||||
if (ImGui::BeginChild("OverworldCanvas", ImVec2(0, 0), true)) {
|
||||
YAZE_REGISTER_WIDGET(canvas, "OverworldCanvas");
|
||||
// Canvas rendering...
|
||||
}
|
||||
ImGui::EndChild();
|
||||
}
|
||||
|
||||
void OverworldEditor::DrawOverworldMapSettings() {
|
||||
YAZE_WIDGET_SCOPE("MapSettings");
|
||||
|
||||
if (BeginTable("SettingsTable", column_count, flags)) {
|
||||
YAZE_REGISTER_WIDGET(table, "SettingsTable");
|
||||
|
||||
for (int map_id = 0; map_id < 64; ++map_id) {
|
||||
YAZE_WIDGET_SCOPE(absl::StrFormat("Map%02X", map_id));
|
||||
|
||||
ImGui::TableNextRow();
|
||||
ImGui::TableSetColumnIndex(0);
|
||||
|
||||
// GfxId input
|
||||
uint8_t gfx_id = maps[map_id].gfx_id;
|
||||
if (gui::InputHexByte("GfxId", &gfx_id)) {
|
||||
YAZE_REGISTER_WIDGET(input, "GfxId");
|
||||
maps[map_id].gfx_id = gfx_id;
|
||||
}
|
||||
|
||||
// ... other inputs
|
||||
}
|
||||
ImGui::EndTable();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- Each editor gets its own top-level scope
|
||||
- Nested scopes create hierarchy automatically
|
||||
- Widgets are discoverable via registry
|
||||
- Test automation can reference: `Overworld/Canvas/canvas:OverworldCanvas`
|
||||
|
||||
#### Phase 3: Add Test Harness Integration (1-2 hours)
|
||||
|
||||
**Enhance ImGuiTestHarness to use Widget Registry**:
|
||||
|
||||
```cpp
|
||||
// imgui_test_harness_service.cc
|
||||
absl::Status ImGuiTestHarnessServiceImpl::Click(
|
||||
const ClickRequest* request, ClickResponse* response) {
|
||||
|
||||
const std::string& target = request->target();
|
||||
|
||||
// Try hierarchical lookup first
|
||||
auto& registry = yaze::gui::WidgetIdRegistry::Instance();
|
||||
ImGuiID widget_id = registry.GetWidgetId(target);
|
||||
|
||||
if (widget_id != 0) {
|
||||
// Found exact match in registry
|
||||
test->ItemClick(widget_id);
|
||||
} else {
|
||||
// Fallback to legacy string-based lookup
|
||||
test->ItemClick(target.c_str());
|
||||
}
|
||||
|
||||
// Check for partial matches if exact fails
|
||||
auto matches = registry.FindWidgets(target);
|
||||
if (!matches.empty()) {
|
||||
response->add_suggestions(matches.begin(), matches.end());
|
||||
}
|
||||
|
||||
return absl::OkStatus();
|
||||
}
|
||||
```
|
||||
|
||||
**Widget Discovery Endpoint**:
|
||||
|
||||
Add to proto:
|
||||
```protobuf
|
||||
// imgui_test_harness.proto
|
||||
message DiscoverWidgetsRequest {
|
||||
string pattern = 1; // e.g. "Overworld/Canvas/*" or "*button*"
|
||||
}
|
||||
|
||||
message DiscoverWidgetsResponse {
|
||||
repeated WidgetInfo widgets = 1;
|
||||
}
|
||||
|
||||
message WidgetInfo {
|
||||
string full_path = 1;
|
||||
string type = 2;
|
||||
uint32 imgui_id = 3;
|
||||
}
|
||||
|
||||
service ImGuiTestHarness {
|
||||
// ... existing RPCs ...
|
||||
rpc DiscoverWidgets(DiscoverWidgetsRequest) returns (DiscoverWidgetsResponse);
|
||||
}
|
||||
```
|
||||
|
||||
**CLI Integration**:
|
||||
|
||||
```bash
|
||||
# Discover all widgets in Overworld editor
|
||||
z3ed agent discover --pattern "Overworld/*"
|
||||
|
||||
# Output:
|
||||
# Overworld/Main/Toolset/button:DrawTile
|
||||
# Overworld/Main/Toolset/button:Pan
|
||||
# Overworld/Main/Canvas/canvas:OverworldMap
|
||||
# Overworld/MapSettings/Table/input:AreaGfx
|
||||
# ...
|
||||
|
||||
# Use in test
|
||||
z3ed agent test --prompt "Click the DrawTile button in Overworld editor"
|
||||
# Auto-resolves to: Overworld/Main/Toolset/button:DrawTile
|
||||
```
|
||||
|
||||
#### Phase 4: Gradual Migration (Ongoing)
|
||||
|
||||
**Priority Order**:
|
||||
1. ✅ Overworld Editor (most complex, most tested)
|
||||
2. Dungeon Editor
|
||||
3. Palette Editor
|
||||
4. Graphics Editor
|
||||
5. Message Editor
|
||||
6. Sprite Editor
|
||||
7. Music Editor
|
||||
8. Screen Editor
|
||||
|
||||
**Migration Strategy**:
|
||||
- Add `YAZE_WIDGET_SCOPE` at function entry points
|
||||
- Replace `##name` with meaningful names + register
|
||||
- Add registration for interactive widgets (buttons, inputs, canvases)
|
||||
- Test with z3ed agent test after each editor
|
||||
|
||||
## Benefits for z3ed Agent Workflow
|
||||
|
||||
### 1. Stable Widget References
|
||||
|
||||
**Before**:
|
||||
```bash
|
||||
z3ed agent test --prompt "Click button:Overworld"
|
||||
# Brittle: depends on exact button label
|
||||
```
|
||||
|
||||
**After**:
|
||||
```bash
|
||||
z3ed agent test --prompt "Click the DrawTile tool in Overworld editor"
|
||||
# Resolves to: Overworld/Main/Toolset/button:DrawTile
|
||||
# Or partial match: */Toolset/button:DrawTile
|
||||
```
|
||||
|
||||
### 2. Widget Discovery for AI
|
||||
|
||||
**Command**:
|
||||
```bash
|
||||
z3ed agent describe --widgets --format yaml > docs/api/yaze-widgets.yaml
|
||||
```
|
||||
|
||||
**Output** (yaze-widgets.yaml):
|
||||
```yaml
|
||||
widgets:
|
||||
- path: Overworld/Main/Toolset/button:DrawTile
|
||||
type: button
|
||||
context:
|
||||
editor: Overworld
|
||||
tab: Main
|
||||
section: Toolset
|
||||
actions: [click]
|
||||
|
||||
- path: Overworld/Main/Canvas/canvas:OverworldMap
|
||||
type: canvas
|
||||
context:
|
||||
editor: Overworld
|
||||
tab: Main
|
||||
section: Canvas
|
||||
actions: [click, drag, scroll]
|
||||
|
||||
- path: Overworld/MapSettings/Table/input:AreaGfx
|
||||
type: input
|
||||
context:
|
||||
editor: Overworld
|
||||
tab: MapSettings
|
||||
map_id: "00-3F (per row)"
|
||||
actions: [type, clear]
|
||||
```
|
||||
|
||||
**LLM Integration**:
|
||||
- AI reads widget catalog to understand available UI
|
||||
- Generates commands referencing stable widget paths
|
||||
- Partial matching allows fuzzy references
|
||||
- Hierarchical structure provides context
|
||||
|
||||
### 3. Automated Test Generation
|
||||
|
||||
**Workflow**:
|
||||
1. User: "Make soldiers wear red armor"
|
||||
2. AI analyzes requirement
|
||||
3. AI queries widget catalog: "What widgets are needed?"
|
||||
4. AI generates test plan:
|
||||
```
|
||||
1. Click Palette/Main/ExportButton
|
||||
2. Type "sprites_aux1" in FileDialog/input:Filename
|
||||
3. Wait for file dialog to close
|
||||
4. Assert file exists
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Testing Strategy
|
||||
|
||||
### Unit Tests
|
||||
|
||||
```cpp
|
||||
TEST(WidgetIdRegistryTest, HierarchicalScopes) {
|
||||
{
|
||||
WidgetIdScope editor("Overworld");
|
||||
EXPECT_EQ(editor.GetFullPath(), "Overworld");
|
||||
|
||||
{
|
||||
WidgetIdScope tab("Main");
|
||||
EXPECT_EQ(tab.GetFullPath(), "Overworld/Main");
|
||||
|
||||
{
|
||||
WidgetIdScope section("Toolset");
|
||||
EXPECT_EQ(section.GetFullPath(), "Overworld/Main/Toolset");
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
TEST(WidgetIdRegistryTest, FindWidgets) {
|
||||
auto& registry = WidgetIdRegistry::Instance();
|
||||
registry.RegisterWidget("Overworld/Main/Toolset/button:DrawTile",
|
||||
"button", 12345);
|
||||
|
||||
auto matches = registry.FindWidgets("*DrawTile");
|
||||
EXPECT_EQ(matches.size(), 1);
|
||||
EXPECT_EQ(matches[0], "Overworld/Main/Toolset/button:DrawTile");
|
||||
}
|
||||
```
|
||||
|
||||
### Integration Tests
|
||||
|
||||
```bash
|
||||
# Test widget discovery via gRPC
|
||||
grpcurl -plaintext -import-path src/app/core/proto -proto imgui_test_harness.proto \
|
||||
-d '{"pattern":"Overworld/*"}' \
|
||||
127.0.0.1:50052 yaze.test.ImGuiTestHarness/DiscoverWidgets
|
||||
|
||||
# Test CLI widget discovery
|
||||
./build/bin/z3ed agent discover --pattern "*/button:*"
|
||||
|
||||
# Test with actual GUI automation
|
||||
./build-grpc-test/bin/z3ed agent test \
|
||||
--prompt "Click the DrawTile button in Overworld editor"
|
||||
```
|
||||
|
||||
## Backwards Compatibility
|
||||
|
||||
### Fallback Mechanism
|
||||
|
||||
```cpp
|
||||
absl::Status ImGuiTestHarnessServiceImpl::Click(...) {
|
||||
// Try new hierarchical system first
|
||||
ImGuiID widget_id = registry.GetWidgetId(target);
|
||||
|
||||
if (widget_id != 0) {
|
||||
test->ItemClick(widget_id);
|
||||
return absl::OkStatus();
|
||||
}
|
||||
|
||||
// Fallback to legacy string-based lookup
|
||||
auto info = test->ItemInfo(target.c_str());
|
||||
if (info.ID != 0) {
|
||||
test->ItemClick(target.c_str());
|
||||
return absl::OkStatus();
|
||||
}
|
||||
|
||||
// Suggest alternatives from registry
|
||||
auto matches = registry.FindWidgets(target);
|
||||
std::string suggestions = absl::StrJoin(matches, ", ");
|
||||
return absl::NotFoundError(
|
||||
absl::StrFormat("Widget not found: %s. Did you mean: %s?",
|
||||
target, suggestions));
|
||||
}
|
||||
```
|
||||
|
||||
**Migration Path**:
|
||||
1. New code uses hierarchical IDs
|
||||
2. Legacy string lookups still work
|
||||
3. Gradual migration editor-by-editor
|
||||
4. Eventually deprecate `##` patterns
|
||||
|
||||
## Success Metrics
|
||||
|
||||
**Technical**:
|
||||
- ✅ Zero duplicate ImGui ID warnings
|
||||
- ✅ 100% of interactive widgets registered
|
||||
- ✅ Widget discovery returns complete catalog
|
||||
- ✅ Test automation can reference any widget by path
|
||||
|
||||
**UX**:
|
||||
- ✅ Natural language prompts resolve to correct widgets
|
||||
- ✅ Partial matching finds widgets without exact names
|
||||
- ✅ Error messages suggest correct widget paths
|
||||
- ✅ Widget catalog enables LLM-driven automation
|
||||
|
||||
**Quality**:
|
||||
- ✅ No performance regression (registry overhead minimal)
|
||||
- ✅ No visual changes to GUI
|
||||
- ✅ Backwards compatible with existing code
|
||||
- ✅ Clean separation of concerns (registry in gui/, not editor/)
|
||||
|
||||

# ImGui ID Management Analysis & Implementation Summary
|
||||
|
||||
**Date**: October 2, 2025
|
||||
**Prepared for**: @scawful
|
||||
**Topic**: GUI widget ID refactoring for z3ed test automation
|
||||
|
||||
## Executive Summary
|
||||
|
||||
I've completed a comprehensive analysis of YAZE's ImGui ID management and created a complete refactoring plan to enable better test automation and eliminate duplicate ID issues.
|
||||
|
||||
### Key Findings
|
||||
|
||||
1. **100+ uses of `##` prefix** - Creates unnamed widgets that are hard to reference from tests
|
||||
2. **Potential ID conflicts** - Multiple widgets with same label (`##table`, `##canvas`) in different scopes
|
||||
3. **No centralized registry** - Test automation has no way to discover available widgets
|
||||
4. **Inconsistent naming** - No convention across editors
|
||||
|
||||
### Proposed Solution
|
||||
|
||||
**Hierarchical Widget ID System** with:
|
||||
- Automatic ID scoping via RAII helpers
|
||||
- Centralized widget registry for discovery
|
||||
- Stable, predictable widget paths
|
||||
- Machine-readable catalog for AI agents
|
||||
|
||||
**Example transformation**:
|
||||
```cpp
|
||||
// Before
|
||||
if (ImGui::BeginChild("##Canvas", ...)) { }
|
||||
|
||||
// After
|
||||
YAZE_WIDGET_SCOPE("Canvas");
|
||||
if (ImGui::BeginChild("OverworldMap", ...)) {
|
||||
YAZE_REGISTER_WIDGET(canvas, "OverworldMap");
|
||||
// Widget path: Overworld/Main/Canvas/canvas:OverworldMap
|
||||
}
|
||||
```
|
||||
|
||||
## Deliverables Created
|
||||
|

|
||||
|
||||
## Implementation Plan Summary
|
||||
|
||||
### Phase 1: Core Infrastructure (2-3 hours) ⚡
|
||||
**Priority**: P0 - Immediate
|
||||
**Status**: Code complete, needs build integration
|
||||
|
||||
**Tasks**:
|
||||
- ✅ Created WidgetIdScope RAII helper
|
||||
- ✅ Created WidgetIdRegistry with discovery
|
||||
- 📋 Add to CMake build system
|
||||
- 📋 Write unit tests
|
||||
|
||||
### Phase 2: Overworld Editor Refactoring (3-4 hours)
|
||||
**Priority**: P0 - This week
|
||||
**Rationale**: Most complex, most tested, immediate value for E2E validation
|
||||
|
||||
**Tasks**:
|
||||
- Add `YAZE_WIDGET_SCOPE` at function boundaries
|
||||
- Replace `##name` with meaningful names
|
||||
- Register all interactive widgets
|
||||
- Test with z3ed agent test
|
||||
|
||||
### Phase 3: Test Harness Integration (1-2 hours)
|
||||
**Priority**: P0 - This week
|
||||
|
||||
**Tasks**:
|
||||
- Add `DiscoverWidgets` RPC to proto
|
||||
- Update Click/Type/Assert handlers to use registry
|
||||
- Add widget suggestions on lookup failures
|
||||
- Test with grpcurl
|
||||
|
||||
### Phase 4: Gradual Migration (4-6 hours per editor)
|
||||
**Priority**: P1-P2 - Next 2-3 weeks
|
||||
|
||||
**Order**:
|
||||
1. Overworld Editor (P0)
|
||||
2. Dungeon Editor (P1)
|
||||
3. Palette Editor (P1)
|
||||
4. Graphics Editor (P1)
|
||||
5. Remaining editors (P2)
|
||||
|
||||
## Benefits for z3ed Agent Workflow
|
||||
|
||||
### 1. Stable Widget References
|
||||
```bash
|
||||
# Before: brittle string matching
|
||||
z3ed agent test --prompt "Click button:Overworld"
|
||||
|
||||
# After: hierarchical path resolution
|
||||
z3ed agent test --prompt "Click the DrawTile tool"
|
||||
# Resolves to: Overworld/Main/Toolset/button:DrawTile
|
||||
```
|
||||
|
||||
### 2. Widget Discovery for AI
|
||||
```bash
|
||||
z3ed agent describe --widgets --format yaml > docs/api/yaze-widgets.yaml
|
||||
```
|
||||
|
||||
**Output includes**:
|
||||
- Full widget paths
|
||||
- Widget types (button, input, canvas, etc.)
|
||||
- Hierarchical context (editor, tab, section)
|
||||
- Available actions (click, type, drag, etc.)
|
||||
|
||||
### 3. Automated Test Generation
|
||||
AI agents can:
|
||||
- Query widget catalog to understand UI structure
|
||||
- Generate commands with stable widget references
|
||||
- Use partial matching for fuzzy lookups
|
||||
- Get helpful suggestions when widgets not found
|
||||
|
||||
## Integration with Existing Work
|
||||
|
||||
### Complements IT-01 (ImGuiTestHarness)
|
||||
- Test harness can now discover widgets dynamically
|
||||
- Widget registry provides stable IDs for Click/Type/Assert RPCs
|
||||
- Better error messages with suggested alternatives
|
||||
|
||||
### Enables IT-02 (CLI Agent Test)
|
||||
- Natural language prompts can resolve to exact widget paths
|
||||
- TestWorkflowGenerator can query available widgets
|
||||
- LLM can read widget catalog to understand UI
|
||||
|
||||
### Supports E2E Validation
|
||||
- Fixes window detection issues with proper ID scoping
|
||||
- Eliminates duplicate ID warnings
|
||||
- Provides foundation for comprehensive GUI testing
|
||||
|
||||
## Next Steps
|
||||
|
||||
### Immediate (Tonight/Tomorrow) - 3 hours
|
||||
1. Add widget_id_registry to CMakeLists.txt
|
||||
2. Write unit tests for WidgetIdScope and WidgetIdRegistry
|
||||
3. Build and verify no compilation errors
|
||||
|
||||
### This Week - 6 hours
|
||||
4. Refactor Overworld Editor (Phase 2)
|
||||
- Start with DrawToolset() and DrawOverworldCanvas()
|
||||
- Add scoping and registration
|
||||
- Test with existing E2E tests
|
||||
|
||||
5. Integrate with test harness (Phase 3)
|
||||
- Add DiscoverWidgets RPC
|
||||
- Update Click handler to use registry
|
||||
- Test widget discovery via grpcurl
|
||||
|
||||
### Next Week - 8 hours
|
||||
6. Continue editor migration (Dungeon, Palette, Graphics)
|
||||
7. Write comprehensive documentation
|
||||
8. Update z3ed guides with widget path examples
|
||||
|
||||
## Success Metrics
|
||||
|
||||
**Technical**:
|
||||
- ✅ Zero duplicate ImGui ID warnings
|
||||
- ✅ All interactive widgets registered and discoverable
|
||||
- ✅ Test automation can reference any widget
|
||||
- ✅ No performance regression
|
||||
|
||||
**UX**:
|
||||
- ✅ Natural language prompts work reliably
|
||||
- ✅ Error messages suggest correct widget paths
|
||||
- ✅ AI agents can understand UI structure
|
||||
- ✅ Tests are maintainable across refactors
|
||||
|
||||
## Risk Mitigation
|
||||
|
||||
### Backwards Compatibility
|
||||
- Fallback mechanism for legacy string lookups
|
||||
- Gradual migration, no breaking changes
|
||||
- Both systems work during transition
|
||||
|
||||
### Performance
|
||||
- Registry overhead minimal (hash map lookup)
|
||||
- Thread-local storage for ID stack
|
||||
- Lazy registration (only interactive widgets)
|
||||
|
||||
### Maintenance
|
||||
- RAII helpers prevent scope leaks
|
||||
- Macros hide complexity from editor code
|
||||
- Centralized registry simplifies updates
|
||||
|
||||
## Code Review Notes
|
||||
|
||||
### Design Decisions
|
||||
|
||||
**Why RAII for scoping?**
|
||||
- Automatic push/pop prevents mistakes
|
||||
- Matches ImGui's own ID scoping semantics
|
||||
- Clean, exception-safe
|
||||
|
||||
**Why thread_local for ID stack?**
|
||||
- ImGui contexts are per-thread
|
||||
- Avoids race conditions
|
||||
- Allows multiple test instances
|
||||
|
||||
**Why singleton for registry?**
|
||||
- Single source of truth
|
||||
- Easy access from any editor
|
||||
- Matches ImGui's singleton pattern
|
||||
|
||||
**Why hierarchical paths?**
|
||||
- Natural organization (editor/tab/section/widget)
|
||||
- Easy to understand and remember
|
||||
- Supports partial matching
|
||||
- Mirrors filesystem conventions
|
||||
|
||||
### Future Enhancements
|
||||
|
||||
1. **Widget State Tracking**
|
||||
- Track enabled/disabled state
|
||||
- Track visibility
|
||||
- Track value changes
|
||||
|
||||
2. **Action Recording**
|
||||
- Record user interactions
|
||||
- Generate tests from recordings
|
||||
- Replay for regression testing
|
||||
|
||||
3. **Visual Tree Inspector**
|
||||
- ImGui debug window showing widget hierarchy
|
||||
- Click to highlight in UI
|
||||
- Real-time registration updates
