Wiki Generator with LSP

Usage

Copypython scripts/generate_docs.py /path/to/project --output WIKI.md

Workflow

1. Detect language from config files (package.json, pyproject.toml, go.mod, etc.)
2. Start LSP server for the detected language
3. Query LSP for symbols, references, types, and call hierarchy
4. Generate WIKI.md with Mermaid diagrams

LSP Servers

If LSP unavailable, scripts fall back to AST/regex analysis.

Output Sections

1. Project Overview (tech stack, dependencies)
2. Architecture (Mermaid flowchart)
3. Project Structure (directory tree)
4. Core Components (classes, functions, APIs)
5. Data Flow (Mermaid sequenceDiagram)
6. Data Model (Mermaid erDiagram, classDiagram)
7. API Reference
8. Configuration
9. Getting Started
10. Development Guide

See references/wiki-template.md for section templates.

Tips

Analysis:

• Exclude: node_modules/, venv/, .git/, dist/, build/
• Prioritize entry points: main.py, index.ts, App.tsx
• For large codebases, focus on src/ or lib/

Formatting:

• Use Mermaid diagrams extensively (flowchart, sequenceDiagram, classDiagram, erDiagram)
• Include code snippets where helpful
• Use tables for structured information
• Add navigation links between sections
• Keep explanations clear and concise

Language Support Details

Fallback Analysis

When LSP is unavailable, the scripts use fallback analyzers:

1. AST Parsing - For Python (ast module) and JavaScript (regex-based)
2. Regex Patterns - For function/class detection in other languages
3. Import Analysis - Parse import statements for dependency graphs

Fallback provides ~70% of LSP accuracy but works without server setup.

Troubleshooting

LSP Server Not Found

CopyError: Could not start LSP server for TypeScript

Solution: Install the required LSP server globally. See Installation column in Language Support table.

Timeout During Analysis

CopyError: LSP request timed out

Solutions:

• Increase timeout: --timeout 120
• Reduce scope: --path src/ instead of entire project
• Check if LSP server is overloaded (large codebase)

Empty or Incomplete Output

Possible causes:

• Project has no recognizable entry points
• LSP server crashed during analysis
• File permissions prevent reading

Solutions:

• Specify entry point: --entry src/main.py
• Check LSP server logs
• Run with --verbose for debug output

Mermaid Diagrams Not Rendering

Mermaid diagrams require a compatible viewer:

• GitHub/GitLab markdown preview
• VS Code with Mermaid extension
• Mermaid Live Editor: https://mermaid.live

Performance Considerations

Tips for large codebases:

• Analyze specific directories: --path src/core
• Skip test files: --exclude "**/test/**"
• Use incremental analysis if available
• Consider generating separate docs per module

Known Limitations

• Monorepos: May need per-package analysis
• Dynamic imports: Not fully detected (Python importlib, JS import())
• Metaprogramming: Dynamically generated code may be missed
• Private symbols: Some LSP servers don't expose private members
• Cross-language projects: Analyze each language separately

Best Practices

1. Run from project root - Ensures correct path resolution
2. Commit WIKI.md - Track documentation changes with code
3. Regenerate periodically - Keep docs in sync with codebase
4. Review output - AI-generated docs may need human refinement
5. Customize template - Adapt wiki-template.md to your needs
