## 🎯 **MISSION: Achieve 100% Test Compatibility**
|
||||
|
||||
**Goal:** All 15 test files must reach 100% compatibility with the JISON parser.
|
||||
|
||||
### **Phase 2A: Fix Partially Working Features** 🔧
|
||||
**Target:** Bring moderate compatibility files to 100%
|
||||
|
||||

|
||||
|
||||
## 🔧 **PHASE 2A: PARTIALLY WORKING FEATURES TO FIX**
|
||||
|
||||
### **1. 🎯 Arrow Parsing Issues** (`lezer-flow-arrows.spec.ts` - 35.7% → 100%)
|
||||
|
||||
**❌ Current Problems:**
|
||||
- Double-edged arrows not parsing: `A <--> B`, `A <==> B`
|
||||
- Direction parsing missing: arrows don't set proper direction
|
||||
- Complex arrow patterns failing
|
||||
|
||||
**✅ Implementation Strategy:**
|
||||
1. **Update Grammar Rules** - Add support for bidirectional arrow patterns
|
||||
2. **Fix Direction Logic** - Implement proper direction setting from arrow types
|
||||
3. **Reference JISON** - Check `flow.jison` for arrow token patterns
|
||||
|
||||
**📁 Key Files:**
|
||||
- Grammar: `packages/mermaid/src/diagrams/flowchart/parser/flow.grammar`

1. **Grammar Refinement** - Fine-tune identifier patterns to avoid token conflicts
|
||||
2. **Keyword Validation** - Implement error handling for reserved keywords
|
||||
3. **Token Precedence** - Fix conflicts between special characters and operators
|
||||
|
||||
**📁 Key Files:**
|
||||
- Grammar: `packages/mermaid/src/diagrams/flowchart/parser/flow.grammar`

|
||||
|
||||
**❌ Current Problems:**
|
||||
- Multi-statement graphs with comments failing
|
||||
- Accessibility features (`accTitle`, `accDescr`) not supported
|
||||
- Complex edge parsing in multi-line graphs
|
||||
|
||||
**✅ Implementation Strategy:**
|
||||
1. **Add Missing Grammar Rules** - Implement `accTitle` and `accDescr` support
|
||||
2. **Fix Multi-statement Parsing** - Improve handling of complex graph structures

|

|
||||
## 📋 **IMPLEMENTATION METHODOLOGY**
|
||||
|
||||
### **🎯 Recommended Approach:**
|
||||
|
||||
#### **Step 1: Priority Order**
|
||||
1. **Vertex Chaining** (0% → 100%) - Most critical missing feature
|
||||
2. **Styling System** (4.2% → 100%) - Core functionality
|
||||
3. **Subgraph System** (9.1% → 100%) - Important structural feature
|
||||
4. **Arrow Improvements** (35.7% → 100%) - Polish existing functionality
|
||||
5. **Edge System** (13.9% → 100%) - Advanced edge features
|
||||
6. **Remaining Features** - Final cleanup
|
||||
|
||||
#### **Step 2: For Each Feature**
|
||||
1. **Analyze JISON Reference** - Study `flow.jison` for grammar patterns
|
||||
2. **Update Lezer Grammar** - Add missing grammar rules to `flow.grammar`
|
||||
3. **Regenerate Parser** - Run `npx lezer-generator --output flow.grammar.js flow.grammar`
|
||||
4. **Implement Semantic Actions** - Add processing logic in `flowParser.ts`
|
||||
5. **Run Tests** - Execute specific test file: `vitest lezer-[feature].spec.ts --run`
|
||||
6. **Iterate** - Fix failing tests one by one until 100% compatibility
|
||||
|
||||
#### **Step 3: Grammar Update Process**
|
||||
```bash
|
||||
# Navigate to parser directory
|
||||
cd packages/mermaid/src/diagrams/flowchart/parser
|
||||
|
||||
# Update flow.grammar file with new rules
|
||||
# Then regenerate the parser
|
||||
npx lezer-generator --output flow.grammar.js flow.grammar
|
||||
|
||||
# Run specific test to check progress
|
||||
cd /Users/knsv/source/git/mermaid
|
||||
vitest packages/mermaid/src/diagrams/flowchart/parser/lezer-[feature].spec.ts --run
|
||||
```

### **🎯 Success Metrics:**
|
||||
- **Target:** All 15 test files at 100% compatibility
|
||||
- **Current:** 6 files at 100%, 9 files need improvement
|
||||
- **Estimated:** ~1,000+ individual test cases to make pass
|
||||
|
||||
---
|
||||
|
||||
## 💡 **CRITICAL SUCCESS FACTORS**
|
||||
|
||||
### **🔑 Key Principles:**
|
||||
1. **100% Compatibility Required** - User expects all tests to pass, not partial compatibility
|
||||
2. **JISON is the Authority** - Always reference `flow.jison` for correct implementation patterns
|
||||
3. **Systematic Approach** - Fix one feature at a time, achieve 100% before moving to next
|
||||
4. **Grammar First** - Most issues are grammar-related, fix grammar before semantic actions
|
||||
|
||||
### **⚠️ Common Pitfalls to Avoid:**
|
||||
1. **Don't Skip Grammar Updates** - Missing grammar rules cause parsing failures
|
||||
2. **Don't Forget Regeneration** - Always regenerate parser after grammar changes
|
||||
3. **Don't Ignore JISON Patterns** - JISON shows exactly how features should work
|
||||
4. **Don't Accept Partial Solutions** - 95% compatibility is not sufficient
|
||||
|
||||
### **🚀 Quick Start for New Agent:**
|
||||
```bash
|
||||
# 1. Check current status
|
||||
cd /Users/knsv/source/git/mermaid
|
||||
vitest packages/mermaid/src/diagrams/flowchart/parser/lezer-flow-vertice-chaining.spec.ts --run
|
||||
|
||||
# 2. Study JISON reference
|
||||
cat packages/mermaid/src/diagrams/flowchart/parser/flow.jison | grep -A5 -B5 "AMP\|vertices"
|
||||
|
||||
# 3. Update grammar
|
||||
cd packages/mermaid/src/diagrams/flowchart/parser
|
||||
# Edit flow.grammar to add missing rules
|
||||
npx lezer-generator --output flow.grammar.js flow.grammar
|
||||
|
||||
# 4. Test and iterate
|
||||
cd /Users/knsv/source/git/mermaid
|
||||
vitest packages/mermaid/src/diagrams/flowchart/parser/lezer-flow-vertice-chaining.spec.ts --run

# Instructions for Mermaid Development
|
||||
|
||||
This document contains important guidelines and standards for working on the Mermaid project.
|
||||
|
||||
## General Guidelines
|
||||
|
||||
- Follow the existing code style and patterns
|
||||
- Write comprehensive tests for new features
|
||||
- Update documentation when adding new functionality
|
||||
- Ensure backward compatibility unless explicitly breaking changes are needed
|
||||
|
||||
## Testing
|
||||
|
||||
- Use vitest for testing (not jest)
|
||||
- Run tests from the project root directory
|
||||
- Use unique test IDs with format of 3 letters and 3 digits (like ABC123) for easy individual test execution
|
||||
- When creating multiple test files with similar functionality, extract shared code into common utilities
|
||||
|
||||
## Package Management
|
||||
|
||||
- This project uses pnpm for package management
|
||||
- Always use pnpm install to add modules
|
||||
- Never use npm in this project
|
||||
|
||||
## Debugging
|
||||
|
||||
- Use logger instead of console for logging in the codebase
|
||||
- Prefix debug logs with 'UIO' for easier identification when testing and reviewing console output
|
||||
|
||||
## Refactoring
|
||||
|
||||
- Always read and follow the complete refactoring instructions in .instructions/refactoring.md
|
||||
- Follow the methodology, standards, testing requirements, and backward compatibility guidelines
|
||||
|
||||
## Diagram Development
|
||||
|
||||
- Documentation for diagram types is located in packages/mermaid/src/docs/
|
||||
- Add links to the sidenav when adding new diagram documentation
|
||||
- Use classDiagram.spec.js as a reference for writing diagram test files
