# Whetstone DSL - Progress Tracker
|
||||
|
||||
> **Purpose:** Living document for cross-session, cross-LLM continuity.
|
||||
> Updated after each work session. The git log is the authoritative source of truth.

|
||||
## Project Overview
|
||||
|
||||
Whetstone is a semantic annotation DSL (SemAnno) and structured editor for cross-language code generation with memory strategy annotations. The core idea: annotate code with memory management intent (`@Reclaim(Tracing)`, `@Owner(Single)`, `@Lifetime(RAII)`, etc.) and generate correct target-language code from a single AST representation.
|
||||
|
||||
**Stack:** C++20, Dear ImGui + SDL2 + OpenGL3, nlohmann-json, vcpkg, CMake

||||
- Editor definitions for all concepts
|
||||
- TextGen definitions for Python output
|
||||
- Phase1Example sandbox model

## Build Infrastructure
|
||||
|
||||
Created in the most recent session:
|
||||
|
||||
| File | Purpose |
|
||||
|------|---------|
|
||||
| `editor/vcpkg.json` | vcpkg manifest (dependencies declaration) |
|
||||
| `editor/CMakePresets.json` | Standardized CMake presets (Windows/Linux) |
|
||||
| `installer/windows/build.ps1` | PowerShell build script (prerequisites, vcpkg, cmake, staging) |
|
||||
| `installer/windows/setup.iss` | Inno Setup installer script (produces `.exe` installer) |
|
||||
| `installer/linux/build.sh` | Bash build script for Linux |
|
||||
| `installer/linux/install.sh` | Linux install script (system deps, desktop entry) |
|
||||
|
||||
### Building on Windows
|
||||
|
||||
```powershell
|
||||
# Prerequisites: VS2022, CMake 3.20+, vcpkg at E:\vcpkg
|
||||
cd E:\Whetstone_DSL\installer\windows
|
||||
.\build.ps1 -Config Release -VcpkgRoot E:\vcpkg
|
||||
|
||||
# Then compile installer (requires Inno Setup 6):
|
||||
& "C:\Users\Bill\AppData\Local\Programs\Inno Setup 6\ISCC.exe" setup.iss
|
||||
```
|
||||
|
||||
### vcpkg Packages Required
|
||||
- `nlohmann-json:x64-windows`
|
||||
- `sdl2:x64-windows`
|
||||
- `imgui[docking-experimental,opengl3-binding]:x64-windows`
|
||||
- `glad:x64-windows`
|
||||
|
||||
### Known Issue: imgui SDL2 Backend
|
||||
vcpkg's imgui 1.91.9 removed the `sdl2-binding` feature (only `sdl3-binding` exists). The SDL2 backend files are vendored locally in `editor/src/imgui_backends/` and compiled directly by CMake.
|
||||
|
||||
---
|
||||
|
||||
## Test Results (Last Verified)
|
||||
|
||||
**Steps 1–47:** All compile and pass (47 executables in `editor/build/Release/`)
|
||||
**Steps 48–75:** Either not started or TDD stubs that don't link yet
|
||||
|
||||
The build only compiles `whetstone_editor` and `orchestrator` targets plus steps 1–47. Steps 51+ are TDD stubs that reference unimplemented code and will fail to link until their implementations exist.
|
||||
|
||||
---
|
||||
|
||||
## Key Source Files
|
||||
|
||||
| File | Contents |
|
||||
|------|----------|
|
||||
| `editor/src/ast/ASTNode.h` | All 33+ AST node classes, JSON serialization |
|
||||
| `editor/src/ast/Generator.h` | PythonGenerator, CppGenerator, ElispGenerator, all canonical annotation classes |
|
||||
| `editor/src/ast/Schema.h` | AST schema validation |
|
||||
| `editor/src/ast/Parser.h` | TreeSitterParser (stub implementations) |
|
||||
| `editor/src/Orchestrator.h` | Orchestrator: Emacs integration, file ops, undo/redo, agent API |
|
||||
| `editor/src/main.cpp` | ImGui editor shell (SDL2 + OpenGL3) |
|
||||
| `editor/src/orchestrator_main.cpp` | Orchestrator standalone process (JSON-RPC server) |
|
||||
| `editor/CMakeLists.txt` | CMake build config (vcpkg-based) |
|
||||
|
||||
---
|
||||
|
||||
## Architecture Notes
|
||||
|
||||
- **Editor** (`whetstone_editor.exe`): ImGui-based GUI. Renders AST as structured editor panels with file tree, toolbar, projection toggles. Currently a Step 12 scaffold — functional but minimal.
|
||||
- **Orchestrator** (`orchestrator.exe`): Standalone JSON-RPC server. Manages AST state, undo/redo journal, file I/O, Emacs daemon integration, agent API.
|
||||
- **Communication**: Editor ↔ Orchestrator via JSON-RPC over stdin/stdout pipes. When launched standalone (no pipe), the editor runs in disconnected mode.
|
||||
- **Generators**: AST → Python, C++, Elisp text output. C++ generator handles canonical memory annotations.
|
||||
- **Parsers**: Text → AST via tree-sitter (currently stub implementations from Sprint 2).
|
||||
|
||||
---
|
||||
|
||||
## What's Next
|
||||
|
||||
The next logical work is **Phase 3b real implementation** (Steps 45–49): replace tree-sitter stubs with real C bindings. This requires:
|
||||
1. Add `tree-sitter`, `tree-sitter-python`, `tree-sitter-cpp`, `tree-sitter-elisp` as CMake FetchContent dependencies
|
||||
2. Replace `TreeSitterParser` stubs in `Parser.h` with real CST-to-AST mapping
|
||||
3. Ensure the existing TDD tests for steps 45–47 pass with real implementations
|
||||
|
||||
Alternatively, jump to **Phase 3c** (Steps 50–54) for classical text editing mode, or **Phase 3e** (Steps 59–63) for WebSocket agent API — these are independent of tree-sitter.
