# 🎯 ANTLR Parser Setup & Testing Guide
|
||||
|
||||
This guide explains how to use the ANTLR parser for Mermaid flowcharts and test it in the development environment.
|
||||
This guide explains how to use the ANTLR parser system for Mermaid diagrams and test it in the development environment. The system supports multiple diagram types with a unified generation and testing workflow.
|
||||
|
||||
## 🚀 Quick Start
|
||||
|
||||
### 1. Generate ANTLR Parser Files
|
||||
### 1. Automatic Generation (Recommended)
|
||||
|
||||
ANTLR files are **automatically generated** during:
|
||||
|
||||
```bash
|
||||
# Generate ANTLR parser files from grammar
|
||||
pnpm antlr:generate
|
||||
```
|
||||
# Fresh installation - ANTLR files generated automatically
|
||||
pnpm install
|
||||
|
||||
### 2. Start Development Server with ANTLR Parser
|
||||
# Build process - ANTLR files regenerated automatically
|
||||
pnpm build
|
||||
|
||||
```bash
|
||||
# Start dev server with ANTLR parser enabled
|
||||
# Development server - ANTLR files generated + watched
|
||||
pnpm dev:antlr
|
||||
```
|
||||
|
||||
### 3. Test ANTLR Parser
|
||||
### 2. Manual Generation (Optional)
|
||||
|
||||
Open your browser to:
|
||||
```bash
|
||||
# Generate ANTLR parser files for ALL supported diagrams
|
||||
pnpm antlr:generate
|
||||
```
|
||||
|
||||
- **ANTLR Test Page**: http://localhost:9000/flowchart-antlr-test.html
|
||||
This single command automatically:
|
||||
|
||||
- 🔍 **Discovers** all `.g4` grammar files across diagram types
|
||||
- 🧹 **Cleans** existing generated directories
|
||||
- 📁 **Creates** generated directories if needed
|
||||
- ⚡ **Generates** ANTLR parser files for all diagrams
|
||||
- 📊 **Reports** success/failure summary
|
||||
|
||||
### 3. Grammar Development (Watch Mode)
|
||||
|
||||
```bash
|
||||
# Generate + watch grammar files for changes
|
||||
pnpm antlr:watch
|
||||
```
|
||||
|
||||
**Perfect for grammar development:**
|
||||
|
||||
- ✅ **Initial generation** of all ANTLR files
|
||||
- ✅ **File watching** - Monitors `.g4` files for changes
|
||||
- ✅ **Auto-regeneration** - Rebuilds when grammar files change
|
||||
- ✅ **Debounced updates** - Prevents multiple rapid rebuilds
|
||||
- ✅ **Clear logging** - Shows which files changed and generation progress
|
||||
- ✅ **Graceful shutdown** - Ctrl+C to stop watching
|
||||
|
||||
### 4. Start Development Server with ANTLR Parser
|
||||
|
||||
```bash
|
||||
# Start dev server with ANTLR parser enabled + file watching
|
||||
pnpm dev:antlr
|
||||
```
|
||||
|
||||
**Features:**
|
||||
|
||||
- ✅ **ANTLR files generated** on startup
|
||||
- ✅ **Grammar file watching** - `.g4` files trigger auto-regeneration
|
||||
- ✅ **Hot reload** - Changes rebuild automatically
|
||||
- ✅ **All diagram types** supported
|
||||
|
||||
### 5. Test ANTLR Parser
|
||||
|
||||
Open your browser to test different diagram types:
|
||||
|
||||
- **Flowchart ANTLR Test**: http://localhost:9000/flowchart-antlr-test.html
|
||||
- **Regular Flowchart Demo**: http://localhost:9000/flowchart.html
|
||||
- **Sequence Diagram Demo**: http://localhost:9000/sequence.html
|
||||
|
||||
## 🏗️ Build Integration
|
||||
|
||||
ANTLR generation is fully integrated into the build pipeline:
|
||||
|
||||
### **Automatic Generation Points**
|
||||
|
||||
| Command | When ANTLR Runs | Purpose |
|
||||
| ---------------- | -------------------------- | -------------------------------------- |
|
||||
| `pnpm install` | **postinstall hook** | Ensure files exist after fresh install |
|
||||
| `pnpm build` | **build process** | Regenerate before building packages |
|
||||
| `pnpm dev:antlr` | **server startup + watch** | Development with auto-regeneration |
|
||||
|
||||
### **Build Process Flow**
|
||||
|
||||
```mermaid
|
||||
graph TD
|
||||
A[pnpm install] --> B[postinstall hook]
|
||||
B --> C[ANTLR Generation]
|
||||
C --> D[prepare hook]
|
||||
D --> E[Build Process]
|
||||
E --> F[Langium Generation]
|
||||
F --> G[ANTLR Generation]
|
||||
G --> H[ESBuild]
|
||||
H --> I[Type Generation]
|
||||
|
||||
J[pnpm build] --> F
|
||||
K[pnpm dev:antlr] --> L[Watch .g4 files]
|
||||
L --> G
|
||||
```
|
||||
|
||||
### **Smart Path Detection**
|
||||
|
||||
The ANTLR generator works from any directory:
|
||||
|
||||
```bash
|
||||
# From project root
|
||||
pnpm antlr:generate # Uses: packages/mermaid/src/diagrams
|
||||
|
||||
# From mermaid package
|
||||
cd packages/mermaid
|
||||
pnpm antlr:generate # Uses: src/diagrams
|
||||
```
|
||||
|
||||

## 🚨 Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
### **Build & Generation Issues**
|
||||
|
||||
1. **ANTLR files not generated**: Run `pnpm antlr:generate`
|
||||
2. **Environment variable not set**: Use `pnpm dev:antlr` instead of `pnpm dev`
|
||||
3. **Diagrams not rendering**: Check browser console for parsing errors
|
||||
4. **Build errors**: Ensure all dependencies are installed with `pnpm install`
|
||||
1. **Missing ANTLR files after install**
|
||||
|
||||
### Getting Help
|
||||
```bash
|
||||
# Manually regenerate
|
||||
pnpm antlr:generate
|
||||
|
||||
- Check the browser console for detailed error messages
|
||||
- Review server logs for build issues
|
||||
- Compare with working Jison parser using regular `pnpm dev`
|
||||
# Check if postinstall ran
|
||||
pnpm install --force
|
||||
```
|
||||
|
||||
2. **Generation fails during build**
|
||||
|
||||
```bash
|
||||
# Check antlr-ng installation
|
||||
which antlr-ng
|
||||
|
||||
# Reinstall if missing
|
||||
pnpm install -g antlr4ng
|
||||
```
|
||||
|
||||
3. **No grammar files found**
|
||||
|
||||
- Ensure `.g4` files are in correct location: `src/diagrams/*/parser/antlr/*.g4`
|
||||
- Check file naming convention: `*Lexer.g4`, `*Parser.g4`
|
||||
- Verify you're running from correct directory
|
||||
|
||||
4. **Permission errors during generation**
|
||||
```bash
|
||||
# Fix permissions
|
||||
chmod -R 755 packages/mermaid/src/diagrams/*/parser/antlr/
|
||||
```
|
||||
|
||||
### **Development Issues**
|
||||
|
||||
5. **ANTLR parser not being used**: Check environment variable `USE_ANTLR_PARSER=true`
|
||||
6. **Environment variable not set**: Use `pnpm dev:antlr` instead of `pnpm dev`
|
||||
7. **Diagrams not rendering**: Check browser console for parsing errors
|
||||
8. **Watch not working**:
|
||||
- For dev server: Restart with `pnpm dev:antlr`
|
||||
- For grammar development: Use `pnpm antlr:watch` instead
|
||||
|
||||
### **Grammar Issues**
|
||||
|
||||
9. **ANTLR generation warnings**
|
||||
|
||||
- Check grammar file syntax with ANTLR tools
|
||||
- Compare with working examples in existing diagrams
|
||||
- Warnings are usually non-fatal but should be addressed
|
||||
|
||||
10. **Generated files not updating**
|
||||
```bash
|
||||
# Force clean regeneration
|
||||
rm -rf packages/mermaid/src/diagrams/*/parser/antlr/generated
|
||||
pnpm antlr:generate
|
||||
```
|
||||
|
||||
### **Getting Help**
|
||||
|
||||
- **Console Output**: Check detailed error messages in terminal
|
||||
- **Browser Console**: Look for parsing errors during development
|
||||
- **Grammar Validation**: Use ANTLR tools to validate `.g4` files
|
||||
- **Compare Examples**: Reference working implementations in existing diagrams
|
||||
- **Build Logs**: Review server logs for build issues
|
||||
- **Fresh Start**: Try `pnpm install --force` for clean installation

|
||||
```
|
||||
|
||||
### 📋 Class Parser
|
||||
|
||||

||||
|
||||
## 🚀 Adding New Diagram Types
|
||||
|
||||
To add ANTLR support for a new diagram type:
|
||||
|
||||
1. **Create Grammar Files**
|
||||
|
||||
```
|
||||
packages/mermaid/src/diagrams/[diagram]/parser/antlr/
|
||||
├── [Diagram]Lexer.g4
|
||||
└── [Diagram]Parser.g4
|
||||
```
|
||||
|
||||
2. **Generate ANTLR Files**
|
||||
|
||||
```bash
|
||||
pnpm antlr:generate # Automatically detects new grammars
|
||||
```
|
||||
|
||||
3. **Implement Architecture**
|
||||
|
||||
- Create `[Diagram]ParserCore.ts` with shared logic
|
||||
- Create `[Diagram]Listener.ts` extending core
|
||||
- Create `[Diagram]Visitor.ts` extending core
|
||||
- Update main parser with pattern selection
|
||||
|
||||
4. **Test and Validate**
|
||||
- Run regression tests
|
||||
- Achieve high compatibility with existing Jison parser
|
||||
- Validate both Listener and Visitor patterns
|
||||
|
||||
The generic ANTLR generation system will automatically handle the new diagram type!
|
||||
|
||||

|
||||
|
||||
## 🎯 Generic ANTLR Generation System
|
||||
|
||||
### **How It Works**
|
||||
|
||||
#### 1. **Auto-Discovery**
|
||||
|
||||
The script automatically finds all `.g4` files in:
|
||||
|
||||
```
|
||||
packages/mermaid/src/diagrams/*/parser/antlr/*.g4
|
||||
```
|
||||
|
||||
#### 2. **Grammar Pairing**
|
||||
|
||||
For each diagram, it looks for:
|
||||
|
||||
- `*Lexer.g4` - Lexical analyzer grammar
|
||||
- `*Parser.g4` - Parser grammar
|
||||
|
||||
#### 3. **Generation Process**
|
||||
|
||||
For each valid grammar pair:
|
||||
|
||||
1. Clean the `generated/` directory
|
||||
2. Create the directory if needed
|
||||
3. Run `antlr-ng` with TypeScript target
|
||||
4. Generate all necessary files
|
||||
|
||||
#### 4. **Generated Files**
|
||||
|
||||
Each diagram gets these generated files:
|
||||
|
||||
- `*Lexer.ts` - Lexer implementation
|
||||
- `*Parser.ts` - Parser implementation
|
||||
- `*ParserListener.ts` - Listener interface
|
||||
- `*ParserVisitor.ts` - Visitor interface
|
||||
- `*.tokens` - Token definitions
|
||||
- `*.interp` - ANTLR interpreter files
|
||||
|
||||
### **Supported Diagrams**
|
||||
|
||||
| Diagram Type | Grammar Files | Generated Location |
|
||||
| ------------- | --------------------------------------- | ----------------------------------------------------------------- |
|
||||
| **Flowchart** | `FlowLexer.g4`, `FlowParser.g4` | `packages/mermaid/src/diagrams/flowchart/parser/antlr/generated/` |
|
||||
| **Sequence** | `SequenceLexer.g4`, `SequenceParser.g4` | `packages/mermaid/src/diagrams/sequence/parser/antlr/generated/` |
|
||||
| **Class** | `ClassLexer.g4`, `ClassParser.g4` | `packages/mermaid/src/diagrams/class/parser/antlr/generated/` |
