-
-## 🏗️ Dual-Pattern Architecture
-
-The ANTLR parser supports both Listener and Visitor patterns with identical behavior:
-
-### 👂 Listener Pattern
-
-- **Event-driven**: Parser controls traversal via enter/exit methods
-- **Push-based**: Parser pushes events to listener callbacks
-- **Automatic traversal**: Uses `ParseTreeWalker.DEFAULT.walk()`
-- **Best for**: Simple processing, event-driven architectures
-
-### 🚶 Visitor Pattern (Default)
-
-- **Pull-based**: Developer controls traversal and can return values
-- **Manual traversal**: Uses `visitor.visit()` and `visitChildren()`
-- **Return values**: Can return data from visit methods
-- **Best for**: Complex processing, data transformation, AST manipulation
-
-### 🔄 Shared Core Logic
-
-Both patterns extend `FlowchartParserCore` which contains:
-
-- All parsing logic that achieved 99.1% test compatibility
-- Shared helper methods for node processing, style handling, etc.
-- Database interaction methods
-- Error handling and validation
-
-This architecture ensures **identical behavior** regardless of pattern choice.
-
-## ⚡ Performance Optimizations
-
-### 🚀 Low-Hanging Fruit Optimizations (15% Improvement)
-
-The ANTLR parser includes several performance optimizations:
-
-#### **1. Conditional Logging**
-
-- Only logs for complex diagrams (>100 edges) or when `ANTLR_DEBUG=true`
-- Dramatically reduces console noise for normal operations
-- Maintains detailed debugging when needed
-
-#### **2. Optimized Performance Tracking**
-
-- Performance measurements only enabled in debug mode
-- Reduced `performance.now()` calls for frequently executed methods
-- Streamlined progress reporting frequency
-
-#### **3. Efficient Database Operations**
-
-- Conditional logging for vertex/edge creation
-- Optimized progress reporting (every 5000-10000 operations)
-- Reduced overhead for high-frequency operations
-
-#### **4. Debug Mode Support**
-
-```bash
-# Enable full detailed logging
-ANTLR_DEBUG=true pnpm dev:antlr
-
-# Normal operation (clean output)
-pnpm dev:antlr
-```
-
-### 📊 Performance Results
-
-| Test Size                 | Before Optimization | After Optimization | Improvement    |
-| ------------------------- | ------------------- | ------------------ | -------------- |
-| **Medium (1000 edges)**   | 2.64s               | 2.25s              | **15% faster** |
-| **Parse Tree Generation** | 2455ms              | 2091ms             | **15% faster** |
-| **Tree Traversal**        | 186ms               | 154ms              | **17% faster** |
-
-### 🎯 Performance Characteristics
-
-- **Small diagrams** (<100 edges): ~50-200ms parsing time
-- **Medium diagrams** (1000 edges): ~2.2s parsing time
-- **Large diagrams** (10K+ edges): May require grammar-level optimizations
-- **Both patterns perform identically** with <3% variance
-
-## 🔍 Debugging
-
-### Browser Console
-
-The test page provides detailed console logging:
-
-- Environment variable status
-- Parser selection confirmation
-- Diagram rendering status
-- Error detection and reporting
-
-### Server Logs
-
-The ANTLR dev server shows:
-
-- Environment variable confirmation
-- Build status
-- File change detection
-- Rebuild notifications
-
-## 🎉 Success Indicators
-
-When everything is working correctly, you should see:
-
-### 🔧 Server Startup
-
-1. ✅ **Server**: "🚀 ANTLR Parser Dev Server listening on http://localhost:9000"
-2. ✅ **Server**: "🎯 Environment: USE_ANTLR_PARSER=true"
-
-### 🎯 Parser Selection (in browser console)
-
-3. ✅ **Console**: "🔧 FlowParser: USE_ANTLR_PARSER = true"
-4. ✅ **Console**: "🔧 FlowParser: Selected parser: ANTLR"
-
-### 📊 Normal Operation (Clean Output)
-
-5. ✅ **Browser**: All test diagrams render as SVG elements
-6. ✅ **Test Page**: Green status indicator showing "ANTLR Parser Active & Rendering Successfully!"
-7. ✅ **Console**: Minimal logging for small/medium diagrams (optimized)
-
-### 🐛 Debug Mode (ANTLR_DEBUG=true)
-
-8. ✅ **Console**: "🎯 ANTLR Parser: Starting parse" (for complex diagrams)
-9. ✅ **Console**: "🎯 ANTLR Parser: Creating visitor" (or "Creating listener")
-10. ✅ **Console**: Detailed performance breakdowns and timing information
-
-## 🚨 Troubleshooting
-
-### Common 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`
-
-### Getting Help
-
-- Check the browser console for detailed error messages
-- Review server logs for build issues
-- Compare with working Jison parser using regular `pnpm dev`

-# Layouts
-
-This page lists the available layout algorithms supported in Mermaid diagrams.
-
-## Supported Layouts
-
-- **elk**: [ELK (Eclipse Layout Kernel)](https://www.eclipse.org/elk/)
-- **tidy-tree**: Tidy tree layout for hierarchical diagrams [Tidy Tree Configuration](/config/tidy-tree)
-- **cose-bilkent**: Cose Bilkent layout for force-directed graphs
-- **dagre**: Dagre layout for layered graphs
-
-## How to Use
-
-You can specify the layout in your diagram's YAML config or initialization options. For example:
-
-```mermaid-example
----
-config:
-  layout: elk
----
-graph TD;
-  A-->B;
-  B-->C;
-```
-
-```mermaid
----
-config:
-  layout: elk

-# Tidy-tree Layout
-
-The **tidy-tree** layout arranges nodes in a hierarchical, tree-like structure. It is especially useful for diagrams where parent-child relationships are important, such as mindmaps.
-
-## Features
-
-- Organizes nodes in a tidy, non-overlapping tree
-- Ideal for mindmaps and hierarchical data
-- Automatically adjusts spacing for readability
-
-## Example Usage
-
-```mermaid-example

-  layout: tidy-tree

-## Tidy Tree Layout Overview
-
-tidy-tree: The bidirectional tidy tree layout
-
-The bidirectional tidy tree layout algorithm creates two separate trees that grow horizontally in opposite directions from a central root node:
-Left tree: grows horizontally to the left (children alternate: 1st, 3rd, 5th...)
-Right tree: grows horizontally to the right (children alternate: 2nd, 4th, 6th...)
-
-This creates a balanced, symmetric layout that is ideal for mindmaps, organizational charts, and other tree-based diagrams.
-
-Layout Structure:
-[Child 3] ← [Child 1] ← [Root] → [Child 2] → [Child 4]
-↓ ↓ ↓ ↓
-[GrandChild] [GrandChild] [GrandChild] [GrandChild]

-/**
- * Bidirectional Tidy-Tree Layout Algorithm for Generic Diagrams
- *
- * This module provides a layout algorithm implementation using the
- * non-layered-tidy-tree-layout algorithm for positioning nodes and edges
- * in tree structures with a bidirectional approach.
- *
- * The algorithm creates two separate trees that grow horizontally in opposite
- * directions from a central root node:
- * - Left tree: grows horizontally to the left (children alternate: 1st, 3rd, 5th...)
- * - Right tree: grows horizontally to the right (children alternate: 2nd, 4th, 6th...)
- *
- * This creates a balanced, symmetric layout that is ideal for mindmaps,
- * organizational charts, and other tree-based diagrams.
- *
- * The algorithm follows the unified rendering pattern and can be used
- * by any diagram type that provides compatible LayoutData.

-/**
- * Render function for the bidirectional tidy-tree layout algorithm
- *
- * This function follows the unified rendering pattern used by all layout algorithms.
- * It takes LayoutData, inserts nodes into DOM, runs the bidirectional tidy-tree layout algorithm,
- * and renders the positioned elements to the SVG.
- *
- * Features:
- * - Alternates root children between left and right trees
- * - Left tree grows horizontally to the left (rotated 90° counterclockwise)
- * - Right tree grows horizontally to the right (rotated 90° clockwise)
- * - Uses tidy-tree algorithm for optimal spacing within each tree
- * - Creates symmetric, balanced layouts
- * - Maintains proper edge connections between all nodes
- *
- * Layout Structure:
- * ```
- * [Child 3] ← [Child 1] ← [Root] → [Child 2] → [Child 4]
- *     ↓           ↓                     ↓           ↓
- * [GrandChild]  [GrandChild]      [GrandChild]  [GrandChild]
- * ```
- *
- * @param layoutData - Layout data containing nodes, edges, and configuration
- * @param svg - SVG element to render to
- * @param helpers - Internal helper functions for rendering
- * @param options - Rendering options

-## ANTLR migration plan for Class Diagrams (parity with Sequence)
-
-This guide summarizes how to migrate the Class diagram parser from Jison to ANTLR (antlr4ng), following the approach used for Sequence diagrams. The goal is full feature parity and 100% test pass rate, while keeping the Jison implementation as the reference until the ANTLR path is green.
-
-### Objectives
-
-- Keep the existing Jison parser as the authoritative reference until parity is achieved
-- Add an ANTLR parser behind a runtime flag (`USE_ANTLR_PARSER=true`), mirroring Sequence
-- Achieve 100% test compatibility with the current Jison behavior, including error cases
-- Keep the public DB and rendering contracts unchanged
-
----
-
-## 1) Prep and references
-
-- Use the Sequence migration as a template for structure, scripts, and patterns:
-  - antlr4ng grammar files: `SequenceLexer.g4`, `SequenceParser.g4`
-  - wrapper: `antlr-parser.ts` providing a Jison-compatible `parse()` and `yy`
-  - generation script: `pnpm --filter mermaid run antlr:sequence`
-- For Class diagrams, identify analogous files:
-  - Jison grammar: `packages/mermaid/src/diagrams/class/parser/classDiagram.jison`
-  - DB: `packages/mermaid/src/diagrams/class/classDb.ts`
-  - Tests: `packages/mermaid/src/diagrams/class/classDiagram.spec.js`
-- Confirm Class diagram features in the Jison grammar and tests: classes, interfaces, enums, relationships (e.g., `--`, `*--`, `o--`, `<|--`, `--|>`), visibility markers (`+`, `-`, `#`, `~`), generics (`<T>`, nested), static/abstract indicators, fields/properties, methods (with parameters and return types), stereotypes (`<< >>`), notes, direction, style/config lines, and titles/accessibility lines if supported.
-
----
-
-## 2) Create ANTLR grammars
-
-- Create `ClassLexer.g4` and `ClassParser.g4` under `packages/mermaid/src/diagrams/class/parser/antlr/`
-- Lexer design guidelines (mirror Sequence approach):
-  - Implement stateful lexing with modes to replicate Jison behavior (e.g., default, line/rest-of-line, config/title/acc modes if used)
-  - Ensure token precedence resolves conflicts between relation arrows and generics (`<|--` vs `<T>`). Prefer longest-match arrow tokens and handle generics in parser context
-  - Accept identifiers that include special characters that Jison allowed (quotes, underscores, digits, unicode as applicable)
-  - Provide tokens for core keywords and symbols: `class`, `interface`, `enum`, relationship operators, visibility markers, `<< >>` stereotypes, `{ }` blocks, `:` type separators, `,` parameter separators, `[` `]` arrays, `<` `>` generics
-  - Reuse common tokens shared across diagrams where appropriate (e.g., `TITLE`, `ACC_...`) if Class supports them
-- Parser design guidelines:
-  - Follow the Jison grammar structure closely to minimize semantic drift
-  - Allow the final statement in the file to omit a trailing newline (to avoid EOF vs NEWLINE mismatches)
-  - Keep non-ambiguous rules for:
-    - Class declarations and bodies (members split into fields/properties vs methods)
-    - Modifiers (visibility, static, abstract)
-    - Types (simple, namespaced, generic with nesting)
-    - Relationships with labels (left->right/right->left forms) and multiplicities
-    - Stereotypes and notes
-    - Optional global lines (title, accTitle, accDescr) if supported by class diagrams
-
----
-
-## 3) Add the wrapper and flag switch
-
-- Add `packages/mermaid/src/diagrams/class/parser/antlr/antlr-parser.ts`:
-  - Export an object `{ parse, parser, yy }` that mirrors the Jison parser shape
-  - `parse(input)` should:
-    - `this.yy.clear()` to reset DB (same as Sequence)
-    - Build ANTLR's lexer/parser, set `BailErrorStrategy` to fail-fast on syntax errors
-    - Walk the tree with a listener that calls classDb methods
-  - Implement no-op bodies for `visitTerminal`, `visitErrorNode`, `enterEveryRule`, `exitEveryRule` (required by ParseTreeWalker)
-  - Avoid `require()`; import from `antlr4ng`
-  - Use minimal `any`; when casting is unavoidable, add clear comments
-- Add `packages/mermaid/src/diagrams/class/parser/classParser.ts` similar to Sequence `sequenceParser.ts`:
-  - Import both the Jison parser and the ANTLR wrapper
-  - Gate on `process.env.USE_ANTLR_PARSER === 'true'`
-  - Normalize whitespace if Jison relies on specific newlines (keep parity with Sequence patterns)
-
----
-
-## 4) Implement the listener (semantic actions)
-
-Map parsed constructs to classDb calls. Typical handlers include:
-
-- Class-like declarations
-  - `db.addClass(id, { type: 'class'|'interface'|'enum', ... })`
-  - `db.addClassMember(id, member)` for fields/properties/methods (capture visibility, static/abstract, types, params)
-  - Stereotypes, annotations, notes: `db.addAnnotation(...)`, `db.addNote(...)` if applicable
-- Relationships
-  - Parse arrow/operator to relation type; map to db constants (composition/aggregation/inheritance/realization/association)
-  - `db.addRelation(lhs, rhs, { type, label, multiplicity })`
-- Title/Accessibility (if supported in Class diagrams)
-  - `db.setDiagramTitle(...)`, `db.setAccTitle(...)`, `db.setAccDescription(...)`
-- Styles/Directives/Config lines as supported by the Jison grammar
-
-Error handling:
-
-- Use BailErrorStrategy; let invalid constructs throw where Jison tests expect failure
-- For robustness parity, only swallow exceptions in places where Jison tolerated malformed content without aborting
-
----
-
-## 5) Scripts and generation
-
-- Add package scripts similar to Sequence in `packages/mermaid/package.json`:
-  - `antlr:class:clean`: remove generated TS
-  - `antlr:class`: run antlr4ng to generate TS into `parser/antlr/generated`
-- Example command (once scripts exist):
-  - `pnpm --filter mermaid run antlr:class`
-
----
-
-## 6) Tests (Vitest)
-
-- Run existing Class tests with the ANTLR parser enabled:
-  - `USE_ANTLR_PARSER=true pnpm vitest packages/mermaid/src/diagrams/class/classDiagram.spec.js --run`
-- Start by making a small focused subset pass, then expand to the full suite
-- Add targeted tests for areas where the ANTLR grammar needs extra coverage (e.g., nested generics, tricky arrow/operator precedence, stereotypes, notes)
-- Keep test expectations identical to Jison’s behavior; only adjust if Jison’s behavior was explicitly flaky and already tolerated in the repo
-
----
-
-## 7) Linting and quality
-
-- Satisfy ESLint rules enforced in the repo:
-  - Prefer imports over `require()`; no empty methods, avoid untyped `any` where reasonable
-  - If `@ts-ignore` is necessary, include a descriptive reason (≥10 chars)
-- Provide minimal types for listener contexts where helpful; keep casts localized and commented
-- Prefix diagnostic debug logs with the project’s preferred prefix if temporary logging is needed (and clean up before commit)
-
----
-
-## 8) Common pitfalls and tips
-
-- NEWLINE vs EOF: allow the last statement without a trailing newline to prevent InputMismatch
-- Token conflicts: order matters; ensure relationship operators (e.g., `<|--`, `--|>`, `*--`, `o--`) win over generic `<`/`>` in the right contexts
-- Identifiers: match Jison’s permissiveness (quoted names, digits where allowed) and avoid over-greedy tokens that eat operators
-- Listener resilience: ensure classes and endpoints exist before adding relations (create implicitly if Jison did so)
-- Error parity: do not swallow exceptions for cases where tests expect failure
-
----
-
-## 9) Rollout checklist
-
-- [ ] Grammar compiles and generated files are committed
-- [ ] `USE_ANTLR_PARSER=true` passes all Class diagram tests
-- [ ] Sequence and other diagram suites remain green
-- [ ] No new ESLint errors; warnings minimized
-- [ ] PR includes notes on parity and how to run the ANTLR tests
-
----
-
-## 10) Quick command reference
-
-- Generate ANTLR targets (after adding scripts):
-  - `pnpm --filter mermaid run antlr:class`
-- Run Class tests with ANTLR parser:
-  - `USE_ANTLR_PARSER=true pnpm vitest packages/mermaid/src/diagrams/class/classDiagram.spec.js --run`
-- Run a single test:
-  - `USE_ANTLR_PARSER=true pnpm vitest packages/mermaid/src/diagrams/class/classDiagram.spec.js -t "some test name" --run`
