# DSK Development Progress

This document tracks the implementation progress of the DSL Development Kit (dsk) command-line tool.

## **Project Overview**
- **Start Date**: December 2024
- **Current Phase**: Phase 3 - Development Workflow (In Progress)
- **Target**: Complete CLI tool for streamlined DSL creation

## **Phase Progress**

### **✅ Phase 0: Tool Setup & Prerequisites** 
**Status**: ✅ Completed  
**Objective**: Establish development environment and project structure

#### **Completed Tasks**:
- [x] Initialize Bun project structure
- [x] Install core dependencies (commander, execa, fs-extra, chalk, chokidar, inquirer)
- [x] Configure TypeScript with proper output settings
- [x] Set up project directory structure (src/commands, src/utils, templates/)
- [x] Configure CLI binary entry point with commander.js
- [x] Create template directories (default/, js-addon/)
- [x] Implement basic CLI with placeholder commands
- [x] Test CLI functionality (`dsk --version`, `dsk --help`, `dsk new`)
- [x] Link command globally for development testing

#### **Key Achievements**:
- ✅ Working CLI tool with proper TypeScript compilation
- ✅ All dependencies installed and configured
- ✅ Project structure matches the plan specification
- ✅ CLI binary (`dsk`) linked and functional

---

### **✅ Phase 1: Interactive Grammar Scaffolding**
**Status**: ✅ Completed  
**Objective**: Create paradigm-aware interactive grammar generation

#### **Tasks**:
- [x] Implement pattern inference engine (`src/utils/inference.ts`)
- [x] Build three-phase interactive flow (Architecture → Features → Syntax)
- [x] Create paradigm-aware grammar generation logic
- [x] Implement project template system
- [x] Connect interactive command to main CLI

#### **Key Achievements**:
- ✅ **Pattern Inference Engine**: 17 built-in token patterns with automatic inference from examples
- ✅ **Interactive Question Flow**: Complete three-phase system (Architecture → Features → Syntax)
- ✅ **Paradigm-Aware Grammar Generation**: Generates different Tree-sitter rules based on language paradigm
- ✅ **Template Processing System**: Dynamic project generation with placeholder replacement
- ✅ **Complete Integration**: `dsk new project --interactive` creates full DSL projects
- ✅ **Robust Error Handling**: Graceful fallbacks when pattern inference fails

#### **Generated Artifacts**:
- **grammar.js**: Complete Tree-sitter grammar with paradigm-specific rules
- **README.md**: Comprehensive project documentation
- **corpus/examples.txt**: Test cases for grammar validation  
- **examples/**: Sample programs in the new language
- **Project structure**: Ready for Tree-sitter development workflow

---

### **✅ Phase 2: Core Build Process**
**Status**: ✅ Completed  
**Objective**: Compile grammar to C library and JS package

#### **Tasks**:
- [x] Implement `tree-sitter generate` command wrapper
- [x] Build C static library with system compiler (gcc/clang) 
- [x] Create JavaScript package with node-gyp compilation
- [x] Implement bun/npm runtime detection
- [x] Generate header files for C library
- [x] Copy and configure JS addon templates

#### **Key Achievements**:
- ✅ **Complete Build Command**: `dsk build` with verbose mode and selective builds (--skip-c, --skip-js)
- ✅ **Tree-sitter Integration**: Automatic parser generation with proper error handling
- ✅ **C Library Compilation**: Full static library build with automatic compiler detection (clang/gcc/cc)
- ✅ **Header Generation**: Proper C header files with function signatures for Tree-sitter language
- ✅ **JavaScript Package Structure**: Complete Node.js addon setup with node-gyp configuration
- ✅ **Runtime Detection**: Automatic bun/npm detection for package building
- ✅ **Template System**: JS addon templates with proper binding.gyp and node.cc files
- ✅ **Source File Management**: Automatic copying of Tree-sitter generated files to JS package

#### **Generated Artifacts**:
- **generated/c/lib/**: Static library (.a files) ready for linking
- **generated/c/include/**: C header files for external usage
- **generated/js/**: Complete Node.js package with native addon configuration
- **Build verification**: Successfully tested with real grammar files

#### **Notable Fixes**
- ✅ JS addon `binding.gyp` updated to correctly include Node-API headers and set `NAPI_VERSION=8`
- ✅ JS template now depends on `node-gyp` to avoid global requirement

### **🚧 Phase 3: Development Workflow**
**Status**: In Progress  
**Objective**: Implement watch mode and testing commands

#### **Tasks**:
- [x] `dsk test`: Wrapper around `tree-sitter test` with streamed output
  - Options: `-u/--update`, `-f/--filter <regex>`, `--cwd <dir>`, `-v/--verbose`
- [x] `dsk dev`: Watch `grammar.js`; on change run build → test with clear status
  - Options: `--debounce <ms>` (default 150), `--quiet`, `-v/--verbose`

---

### **⏳ Phase 4: Editor Integration**
**Status**: 📋 Pending  
**Objective**: Generate syntax highlighting for Tree-sitter queries and editors: Neovim, Emacs, VS Code

#### **Initial Step Completed**:
- [x] Generate `generated/editors/tree-sitter/highlights.scm`
- [x] Generate Neovim setup instructions
- [x] Generate minimal Emacs major mode scaffold
- [x] Generate VS Code TextMate grammar and language configuration

---

### **⏳ Phase 5: Packaging & Distribution**
**Status**: 📋 Pending  
**Objective**: Create distributable artifacts

#### **Initial Step Completed**:
- [x] `dsk package`: Builds, tars `generated/c`, and packs JS (`bun pack` → `npm pack` fallback)

---

## **Implementation Notes**

### **Technology Decisions**
- **Runtime**: Bun (primary) with Node.js fallback
- **Language**: TypeScript for type safety and modern features
- **CLI Framework**: commander.js for robust argument parsing
- **File Operations**: fs-extra for enhanced file system utilities

### **Architecture Decisions**
- **Modular Commands**: Each command (new, build, dev, test, highlight, package) in separate files
- **Extensible Inference**: Pattern library with solid defaults, user customizable
- **Template-Driven**: Convention over configuration through project templates

---

## **Next Steps**
1. Phase 3 polish:
   - Add `--debounce <ms>` to `dsk dev` (default 150ms) and `--quiet` to suppress non-error logs
   - Pass `--verbose` through to `dsk build` and `dsk test`
2. Phase 4 expansion (reduced scope):
   - Flesh out templates for Neovim, Emacs, VS Code (Tree-sitter queries based)
3. Phase 5 completion:
   - Include README and checksums in `dist/`
   - Verify packed JS `.tgz` metadata (name/version)
4. Docs:
   - Update `dsk-cli/README.md` with new commands and examples
