🔗 DocWeave

CLI tool powered by GitHub Copilot CLI that analyzes git repositories and generates beautiful documentation

DocWeave is a command-line tool that analyzes your git repository and generates organized documentation using GitHub Copilot CLI. It transforms your commit history into markdown docs, Mermaid diagrams, and AI-powered insights.

✨ Features

🤖 AI-Powered Analysis: Uses GitHub Copilot CLI to understand code changes and provide context
📊 Visual Diagrams: Generates Mermaid diagrams (timelines, file relationships, importance charts)
📝 Auto-Documentation: Creates organized markdown files in DocweaveDocs/ folder
🎯 Next Steps: Suggests actionable next steps based on code analysis
⚡ Simple CLI: Just run docweave analyze in any git repository
🔄 Graceful Fallback: Works even without Copilot CLI using intelligent heuristics

📖 How the DocWeave Process Works

Step-by-Step Process

When you run docweave analyze, here's what happens:

1. Repository Detection 📂

📊 Detecting git repository...
✅ Detected git repository: your-repo
ℹ️  Repository path: /path/to/your/repo

DocWeave checks if the current directory (or specified path) is a git repository
It looks for a .git folder, checking up to 5 parent directories if needed
If no git repository is found, it shows a clear error message with instructions

2. GitHub Copilot CLI Check 🤖

📊 Checking GitHub Copilot CLI...
✅ GitHub Copilot CLI is available - using enhanced analysis

OR if not available:

⚠️  GitHub Copilot CLI not available: [error message]
ℹ️  Using fallback analysis (still generates great docs!)

What happens if GitHub credentials aren't detected:

Copilot CLI Not Installed: DocWeave detects this and automatically falls back to heuristic-based analysis. You'll see a warning message, but the tool continues working.
Copilot CLI Installed but Not Authenticated: Same behavior - fallback analysis is used. The tool will still generate documentation, just without AI-powered insights.
Copilot CLI Available and Authenticated: Enhanced AI-powered analysis is used for each commit, providing deeper insights, better summaries, and more contextual next steps.

Key Point: DocWeave always works, regardless of Copilot CLI status. It gracefully degrades to intelligent heuristics when Copilot isn't available.

3. Commit Analysis 📊

📊 Analyzing recent commits (limit: 5)...
✅ Found 5 commit(s) to analyze

📊 Analyzing commits with AI-powered insights...
  [1/5] abc1234 - Fix bug in login... ✅ ✓
  [2/5] def5678 - Add new feature... ✅ ✓
  ...

For each commit:

With Copilot CLI: The commit diff and message are analyzed using AI to extract:
- Summary of changes
- Why the change was made
- Suggested next steps
- Importance level (low/medium/high)
Without Copilot CLI: Intelligent heuristics analyze:
- Commit message patterns (e.g., "fix", "feat", "test")
- File types changed
- Code diff patterns
- Generates similar insights using rule-based analysis

4. Documentation Generation 📝

📊 Generating documentation...
✅ Documentation generated successfully!

DocWeave creates:

CHANGES.md: Detailed analysis of each commit
NARRATIVE.md: Storytelling narrative of development journey
DIAGRAMS.md: Mermaid diagrams (timelines, file relationships, importance charts)
NEXT_STEPS.md: Actionable next steps based on analysis

5. Output Summary 📁

📁 Generated Files:
  ✓ CHANGES.md - Detailed commit analysis
  ✓ NARRATIVE.md - Development narrative
  ✓ DIAGRAMS.md - Mermaid diagrams
  ✓ NEXT_STEPS.md - Suggested next steps

📂 Documentation saved to: /path/to/repo/DocweaveDocs

All files are saved in the DocweaveDocs/ folder in your repository root.

🔧 GitHub Copilot CLI Setup

Installation

Option 1: Homebrew (macOS/Linux)

brew install copilot-cli

Option 2: npm (requires Node.js 22+)

npm install -g @github/copilot

Option 3: Install Script

curl -fsSL https://gh.io/copilot-install | bash

Authentication

Method 1: Interactive Login

🔍 Troubleshooting

"command not found: docweave"

Check if installed:
```
which docweave
pip show docweave
```

Add to PATH:

export PATH="$HOME/.local/bin:$PATH"
# Add this to ~/.zshrc or ~/.bashrc

Reinstall:
```
cd DocWeave
./install.sh
```

"Module not found" errors

Make sure you're using Python 3.10+:

python3 --version  # Should be 3.10 or higher

"Path is not a git repository"

Ensure you're in a directory with a .git folder
Or use --path to specify a repository:
```
docweave analyze --path /path/to/repo
```

GitHub URL Error

If you see an error about GitHub URLs:

DocWeave requires local git repositories

Clone the repository first:

git clone https://github.com/owner/repo.git
cd repo
docweave analyze

Copilot CLI Issues

"copilot: command not found"

# Check installation
which copilot
copilot --version

# Install if needed
brew install copilot-cli
# or
npm install -g @github/copilot

"Authentication required"

# Authenticate
copilot
# Then type: /login
# Or set token:
export GH_TOKEN=your_token_here

Note: DocWeave works without Copilot CLI - you'll just get fallback analysis instead of AI-powered insights.
