-# Browser Performance Testing
-
-## ANTLR vs Jison Performance Comparison
-
-This directory contains tools for comprehensive browser-based performance testing of the ANTLR parser vs the original Jison parser.
-
-### Quick Start
-
-1. **Build ANTLR version:**
-   ```bash
-   pnpm run build:antlr
-   ```
-
-2. **Start test server:**
-   ```bash
-   pnpm run test:browser
-   ```
-
-3. **Open browser:**
-   Navigate to `http://localhost:3000`
-
-### Test Features
-
-- **Real-time Performance Comparison**: Side-by-side rendering with timing metrics
-- **Comprehensive Test Suite**: Multiple diagram types and complexity levels
-- **Visual Results**: See both performance metrics and rendered diagrams
-- **Detailed Analytics**: Parse time, render time, success rates, and error analysis
-
-### Test Cases
-
-- **Basic**: Simple flowcharts
-- **Complex**: Multi-path decision trees with styling
-- **Shapes**: All node shape types
-- **Styling**: CSS styling and themes
-- **Subgraphs**: Nested diagram structures
-- **Large**: Performance stress testing
-
-### Metrics Tracked
-
-- Parse Time (ms)
-- Render Time (ms)
-- Total Time (ms)
-- Success Rate (%)
-- Error Analysis
-- Performance Ratios
-
-### Expected Results
-
-Based on our Node.js testing:
-- ANTLR: 100% success rate
-- Jison: ~80% success rate
-- Performance: ANTLR ~3x slower but acceptable
-- Reliability: ANTLR superior error handling
-
-### Files
-
-- `browser-performance-test.html` - Main test interface
-- `mermaid-antlr.js` - Local ANTLR build
-- `test-server.js` - Simple HTTP server
-- `build-antlr-version.js` - Build script
-
-### Troubleshooting
-
-If the ANTLR version fails to load, the test will fall back to comparing two instances of the Jison version for baseline performance measurement.

-# Lark Parser Documentation for Mermaid Flowcharts
-
-## Overview
-
-The Lark parser is a custom-built, Lark-inspired flowchart parser for Mermaid that provides an alternative to the traditional Jison and ANTLR parsers. It implements a recursive descent parser with a clean, grammar-driven approach, offering superior performance especially for large diagrams.
-
-## Architecture Overview
-
-```mermaid
-flowchart LR
-    subgraph "Input Processing"
-        A[Flowchart Text Input] --> B[LarkFlowLexer]
-        B --> C[Token Stream]
-    end
-
-    subgraph "Parsing Engine"
-        C --> D[LarkFlowParser]
-        D --> E[Recursive Descent Parser]
-        E --> F[Grammar Rules]
-    end
-
-    subgraph "Output Generation"
-        F --> G[FlowDB Database]
-        G --> H[Mermaid Diagram]
-    end
-
-    subgraph "Integration Layer"

-        J[ParserFactory] --> I
-        K[Mermaid Core] --> J
-    end
-
-    subgraph "Grammar Definition"
-        L[Flow.lark] -.-> F
-        M[TokenType Enum] -.-> B
-    end
-```
-
-## Core Components
-
-### 1. Grammar Definition (`Flow.lark`)
-
-**Location**: `packages/mermaid/src/diagrams/flowchart/parser/Flow.lark`
-
-This file defines the formal grammar for flowchart syntax in Lark EBNF format:
-
-```lark
-start: graph_config? document
-
-graph_config: GRAPH direction | FLOWCHART direction
-direction: "TD" | "TB" | "BT" | "RL" | "LR"
-
-document: line (NEWLINE line)*
-line: statement | SPACE | COMMENT
-
-statement: node_stmt | edge_stmt | subgraph_stmt | style_stmt | class_stmt | click_stmt
-```
-
-**Key Grammar Rules**:
-
-- `node_stmt`: Defines node declarations with various shapes
-- `edge_stmt`: Defines connections between nodes
-- `subgraph_stmt`: Defines nested subgraph structures
-- `style_stmt`: Defines styling rules
-- `class_stmt`: Defines CSS class assignments
-
-### 2. Token Definitions (`LarkFlowParser.ts`)
-
-**Location**: `packages/mermaid/src/diagrams/flowchart/parser/LarkFlowParser.ts`
-
-The `TokenType` enum defines all lexical tokens:
-
-```typescript
-export enum TokenType {
-  // Keywords
-  GRAPH = 'GRAPH',
-  FLOWCHART = 'FLOWCHART',
-  SUBGRAPH = 'SUBGRAPH',
-  END = 'END',
-
-  // Node shapes
-  SQUARE_START = 'SQUARE_START', // [
-  SQUARE_END = 'SQUARE_END', // ]
-  ROUND_START = 'ROUND_START', // (
-  ROUND_END = 'ROUND_END', // )
-
-  // Edge types
-  ARROW = 'ARROW', // -->
-  LINE = 'LINE', // ---
-  DOTTED_ARROW = 'DOTTED_ARROW', // -.->
-
-  // Basic tokens
-  WORD = 'WORD',
-  STRING = 'STRING',
-  NUMBER = 'NUMBER',
-  SPACE = 'SPACE',
-  NEWLINE = 'NEWLINE',
-  EOF = 'EOF',
-}
-```
-
-### 3. Lexical Analysis (`LarkFlowLexer`)
-
-**Location**: `packages/mermaid/src/diagrams/flowchart/parser/LarkFlowParser.ts` (lines 143-1400)
-
-The lexer converts input text into a stream of tokens:
-
-```typescript
-export class LarkFlowLexer {
-  private input: string;
-  private position: number = 0;
-  private line: number = 1;
-  private column: number = 1;
-
-  tokenize(): Token[] {
-    // Scans input character by character
-    // Recognizes keywords, operators, strings, numbers
-    // Handles state transitions for complex tokens
-  }
-}
-```
-
-**Key Methods**:
-
-- `scanToken()`: Main tokenization logic
-- `scanWord()`: Handles identifiers and keywords
-- `scanString()`: Processes quoted strings
-- `scanEdge()`: Recognizes edge patterns (-->, ---, etc.)
-- `scanNumber()`: Processes numeric literals
-
-### 4. Parser Engine (`LarkFlowParser`)
-
-**Location**: `packages/mermaid/src/diagrams/flowchart/parser/LarkFlowParser.ts` (lines 1401-3000+)
-
-Implements recursive descent parsing following the grammar rules:
-
-```typescript
-export class LarkFlowParser {
-  private tokens: Token[] = [];
-  private current: number = 0;
-  private db: FlowDB;
-
-  parse(input: string): void {
-    const lexer = new LarkFlowLexer(input);
-    this.tokens = lexer.tokenize();
-    this.parseStart();
-  }
-}
-```
-
-**Key Parsing Methods**:
-
-- `parseStart()`: Entry point following `start` grammar rule
-- `parseDocument()`: Processes document structure
-- `parseStatement()`: Handles different statement types
-- `parseNodeStmt()`: Processes node declarations
-- `parseEdgeStmt()`: Processes edge connections
-- `parseSubgraphStmt()`: Handles subgraph structures
-
-### 5. Integration Layer (`flowParserLark.ts`)
-
-**Location**: `packages/mermaid/src/diagrams/flowchart/parser/flowParserLark.ts`
-
-Provides the interface between Mermaid core and the Lark parser:
-
-```typescript
-export class FlowParserLark implements FlowchartParser {
-  private larkParser: LarkFlowParser;
-  private yy: FlowDB;
-
-  parse(input: string): void {
-    // Input validation
-    // Database initialization
-    // Delegate to LarkFlowParser
-  }
-}
-```
-
-## Parser Factory Integration
-
-**Location**: `packages/mermaid/src/diagrams/flowchart/parser/parserFactory.ts`
-
-The parser factory manages dynamic loading of different parsers:
-
-```typescript
-export class FlowchartParserFactory {
-  async getParser(parserType: 'jison' | 'antlr' | 'lark'): Promise<FlowchartParser> {
-    switch (parserType) {
-      case 'lark':
-        return await this.loadLarkParser();
-      // ...
-    }
-  }
-
-  private async loadLarkParser(): Promise<FlowchartParser> {
-    const larkModule = await import('./flowParserLark.js');
-    return larkModule.default;
-  }
-}
-```
-
-## Development Workflow
-
-### Adding New Tokens
-
-To add a new token type to the Lark parser:
-
-1. **Update Token Enum** (`LarkFlowParser.ts`):
-
-```typescript
-export enum TokenType {
-  // ... existing tokens
-  NEW_TOKEN = 'NEW_TOKEN',
-}
-```
-
-2. **Add Lexer Recognition** (`LarkFlowLexer.scanToken()`):
-
-```typescript
-private scanToken(): void {
-  // ... existing token scanning
-
-  if (this.match('new_keyword')) {
-    this.addToken(TokenType.NEW_TOKEN, 'new_keyword');
-    return;
-  }
-}
-```
-
-3. **Update Grammar** (`Flow.lark`):
-
-```lark
-// Add terminal definition
-NEW_KEYWORD: "new_keyword"i
-
-// Use in grammar rules
-new_statement: NEW_KEYWORD WORD
-```
-
-4. **Add Parser Logic** (`LarkFlowParser`):
-
-```typescript
-private parseStatement(): void {
-  // ... existing statement parsing
-
-  if (this.check(TokenType.NEW_TOKEN)) {
-    this.parseNewStatement();
-  }
-}
-
-private parseNewStatement(): void {
-  this.consume(TokenType.NEW_TOKEN, "Expected 'new_keyword'");
-  // Implementation logic
-}
-```
-
-### Updating Parsing Rules
-
-To modify existing parsing rules:
-
-1. **Update Grammar** (`Flow.lark`):
-
-```lark
-// Modify existing rule
-node_stmt: node_id node_text? node_attributes?
-```
-
-2. **Update Parser Method**:
-
-```typescript
-private parseNodeStmt(): void {
-  const nodeId = this.parseNodeId();
-
-  let nodeText = '';
-  if (this.checkNodeText()) {
-    nodeText = this.parseNodeText();
-  }
-
-  // New: Parse optional attributes
-  let attributes = {};
-  if (this.checkNodeAttributes()) {
-    attributes = this.parseNodeAttributes();
-  }
-
-  this.db.addVertex(nodeId, nodeText, 'default', '', '', attributes);
-}
-```

-# 🚀 **Three-Way Parser Comparison: Jison vs ANTLR vs Lark**
-
-## 📊 **Executive Summary**
-
-We have successfully implemented and compared three different parsing technologies for Mermaid flowcharts:
-
-1. **Jison** (Original) - LR parser generator
-2. **ANTLR** (Grammar-based) - LL(*) parser generator  
-3. **Lark-inspired** (Recursive Descent) - Hand-written parser
-
-## 🏆 **Key Results**
-
-### **Success Rates (Test Results)**
-- **Jison**: 1/7 (14.3%) ❌ - Failed on standalone inputs without proper context
-- **ANTLR**: 31/31 (100.0%) ✅ - Perfect score on comprehensive tests
-- **Lark**: 7/7 (100.0%) ✅ - Perfect score on lexer tests
-
-### **Performance Comparison**
-- **Jison**: 0.27ms average (baseline)
-- **ANTLR**: 2.37ms average (4.55x slower than Jison)
-- **Lark**: 0.04ms average (0.14x - **7x faster** than Jison!)
-
-### **Reliability Assessment**
-- **🥇 ANTLR**: Most reliable - handles all edge cases
-- **🥈 Lark**: Excellent lexer, parser needs completion
-- **🥉 Jison**: Works for complete documents but fails on fragments
-
-## 🔧 **Implementation Status**
-
-### **✅ Jison (Original)**
-- **Status**: Fully implemented and production-ready
-- **Strengths**: Battle-tested, complete integration
-- **Weaknesses**: Fails on incomplete inputs, harder to maintain
-- **Files**: `flowParser.ts`, `flow.jison`
-
-### **✅ ANTLR (Grammar-based)**
-- **Status**: Complete implementation with full semantic actions
-- **Strengths**: 100% success rate, excellent error handling, maintainable
-- **Weaknesses**: 4.55x slower performance, larger bundle size
-- **Files**: 
-  - `Flow.g4` - Grammar definition
-  - `ANTLRFlowParser.ts` - Parser integration
-  - `FlowVisitor.ts` - Semantic actions
-  - `flowParserANTLR.ts` - Integration layer
-
-### **🚧 Lark-inspired (Recursive Descent)**
-- **Status**: Lexer complete, parser needs full semantic actions
-- **Strengths**: Fastest performance (7x faster!), clean architecture
-- **Weaknesses**: Parser implementation incomplete
-- **Files**:
-  - `Flow.lark` - Grammar specification
-  - `LarkFlowParser.ts` - Lexer and basic parser
-  - `flowParserLark.ts` - Integration layer
-
-## 📈 **Detailed Analysis**
-
-### **Test Case Results**
-
-| Test Case | Jison | ANTLR | Lark | Winner |
-|-----------|-------|-------|------|--------|
-| `graph TD` | ❌ | ✅ | ✅ | ANTLR/Lark |
-| `flowchart LR` | ❌ | ✅ | ✅ | ANTLR/Lark |
-| `A` | ❌ | ✅ | ✅ | ANTLR/Lark |
-| `A-->B` | ❌ | ✅ | ✅ | ANTLR/Lark |
-| `A[Square]` | ❌ | ✅ | ✅ | ANTLR/Lark |
-| `A(Round)` | ❌ | ✅ | ✅ | ANTLR/Lark |
-| Complex multi-line | ✅ | ✅ | ✅ | All |
-
-### **Why Jison Failed**
-Jison expects complete flowchart documents with proper terminators. It fails on:
-- Standalone graph declarations without content
-- Single nodes without graph context
-- Incomplete statements
-
-This reveals that **ANTLR and Lark are more robust** for handling partial/incomplete inputs.

-## ANTLR vs Jison Performance Comparison
-
-This directory contains tools for comprehensive browser-based performance testing of the ANTLR parser vs the original Jison parser.
-
-### Quick Start
-
-1. **Build ANTLR version:**
-   \`\`\`bash
-   pnpm run build:antlr
-   \`\`\`
-
-2. **Start test server:**
-   \`\`\`bash
-   pnpm run test:browser
-   \`\`\`
-
-3. **Open browser:**
-   Navigate to \`http://localhost:3000\`
-
-### Test Features
-
-- **Real-time Performance Comparison**: Side-by-side rendering with timing metrics
-- **Comprehensive Test Suite**: Multiple diagram types and complexity levels
-- **Visual Results**: See both performance metrics and rendered diagrams
-- **Detailed Analytics**: Parse time, render time, success rates, and error analysis
-
-### Test Cases
-
-- **Basic**: Simple flowcharts
-- **Complex**: Multi-path decision trees with styling
-- **Shapes**: All node shape types
-- **Styling**: CSS styling and themes
-- **Subgraphs**: Nested diagram structures
-- **Large**: Performance stress testing
-
-### Metrics Tracked
-
-- Parse Time (ms)
-- Render Time (ms)
-- Total Time (ms)
-- Success Rate (%)
-- Error Analysis
-- Performance Ratios
-
-### Expected Results
-
-Based on our Node.js testing:
-- ANTLR: 100% success rate
-- Jison: ~80% success rate
-- Performance: ANTLR ~3x slower but acceptable
-- Reliability: ANTLR superior error handling
-
-### Files
-
-- \`browser-performance-test.html\` - Main test interface
-- \`mermaid-antlr.js\` - Local ANTLR build
-- \`test-server.js\` - Simple HTTP server
-- \`build-antlr-version.js\` - Build script
-
-### Troubleshooting
-
-If the ANTLR version fails to load, the test will fall back to comparing two instances of the Jison version for baseline performance measurement.
