## Advanced Features

### Intelligent Chunking & Parallel Processing

For large diffs, git-llm-tool automatically uses intelligent chunking to break down changes into manageable pieces:

- **Automatic Threshold Detection**: Diffs larger than 12,000 tokens are automatically chunked
- **Smart Splitting**: Prioritizes file-based splitting, then hunks, then size-based splitting
- **Parallel Processing**: Multiple chunks processed simultaneously for faster results
- **Progress Indicators**: Beautiful progress bars show real-time processing status

```bash
# Enable verbose mode to see chunking details
git-llm commit --verbose

# Example output:
# 🔄 Analyzing diff and creating intelligent chunks...
# ✅ Created 4 intelligent chunks
# 📄 Smart chunking stats:
#    Total chunks: 4
#    File chunks: 2
#    Hunk chunks: 2
#    Complete files: 2
# 🚀 Processing 4 chunks in parallel (4/4 completed)...
# ✅ Parallel processing completed: 4/4 chunks successful
# 🔄 Combining 4 summaries into final commit message...
# ✅ Final commit message generated successfully
```

### Hybrid Ollama Processing

Use local Ollama for chunk processing combined with cloud LLM for final quality:

#### Setup Ollama
```bash
# Install Ollama (macOS/Linux)
curl -fsSL https://ollama.ai/install.sh | sh

# Pull a model
ollama pull llama3:8b
# or
ollama pull llama3.1:8b
ollama pull codellama:7b
```

#### Enable Hybrid Mode
```bash
# Enable hybrid processing
git-llm config set llm.use_ollama_for_chunks true
git-llm config set llm.ollama_model llama3:8b

# Verify Ollama is running
curl http://localhost:11434/api/version
```

#### How It Works
1. **Map Phase**: Each chunk processed locally with Ollama (fast, private)
2. **Reduce Phase**: Final combination using cloud LLM (high quality)
3. **Cost Efficient**: Reduces cloud API usage while maintaining quality
4. **Privacy**: Sensitive code chunks processed locally

```bash
# With verbose mode, you'll see:
git-llm commit --verbose

# 🔄 Hybrid processing mode:
#    Map phase (chunks): Ollama (llama3:8b)
#    Reduce phase (final): gpt-4o
# 🚀 Processing 4 chunks in parallel (4/4 completed)...
```

### LangChain Integration

Advanced LLM provider management with automatic model selection:

- **Automatic Provider Detection**: Based on model name
- **Retry Logic**: Exponential backoff for failed requests
- **Rate Limiting**: Prevents API quota exhaustion
- **Error Recovery**: Graceful fallbacks

```

## Usage Examples

### Basic Workflow
```bash
# 1. Make changes to your code
echo "console.log('Hello World');" > app.js

# 2. Stage changes
git add app.js

# 3. Generate commit message with review
git-llm commit
# Opens your editor with AI-generated message for review

# 4. Or apply directly
git-llm commit --apply
```

### Using Different Models
```bash
# Use specific model for this commit
git-llm commit --model claude-3-sonnet

# Use different language
git-llm commit --language zh
```

### Project-specific Configuration
Create `.git-llm-tool.yaml` in your project root:
```yaml
llm:
  default_model: 'claude-3-sonnet'
  language: 'zh'
editor:
  preferred_editor: 'code --wait'
jira:
  enabled: true
  branch_regex: '^(feat|fix|docs)\/([A-Z]+-\d+)\/.+$'
```

## Supported Models

### OpenAI
- `gpt-4o` (recommended)
- `gpt-4o-mini`
- `gpt-4-turbo`
- `gpt-3.5-turbo`

### Anthropic Claude
- `claude-3-5-sonnet-20241022` (recommended)
- `claude-3-5-haiku-20241022`
- `claude-3-opus-20240229`

### Google Gemini
- `gemini-1.5-pro`
- `gemini-1.5-flash`

### Azure OpenAI
- Any deployment of the above OpenAI models

### Ollama (Local)
For hybrid processing (chunk processing only):
- `llama3:8b` (recommended)
- `llama3.1:8b`
- `llama3:70b`

## Git Custom Command Integration

You can integrate git-llm as a native git subcommand, allowing you to use `git llm` instead of `git-llm`.

### Method 1: Git Aliases (Recommended)

Add aliases to your git configuration:

```bash
# Add git aliases for all commands
git config --global alias.llm-commit '!git-llm commit'
git config --global alias.llm-changelog '!git-llm changelog'
git config --global alias.llm-config '!git-llm config'

# Or create a general alias
git config --global alias.llm '!git-llm'
```

Now you can use:
```bash
git llm commit              # Instead of git-llm commit
git llm changelog           # Instead of git-llm changelog
git llm config get          # Instead of git-llm config get

# Or with specific aliases
git llm-commit              # Direct alias to git-llm commit
git llm-changelog           # Direct alias to git-llm changelog
```

### Method 2: Shell Aliases

Add to your shell profile (`.bashrc`, `.zshrc`, etc.):

```bash
# Simple alias
alias gllm='git-llm'

# Or git-style aliases
alias gllmc='git-llm commit'
alias gllmcl='git-llm changelog'
alias gllmcfg='git-llm config'
```

Usage:
```bash
gllm commit                 # git-llm commit
gllmc                       # git-llm commit
gllmcl                      # git-llm changelog
```

### Method 3: Custom Git Script

Create a custom git command script:

```bash
# Create git-llm script in your PATH
sudo tee /usr/local/bin/git-llm > /dev/null << 'EOF'
#!/bin/bash
# Git-LLM integration script
exec git-llm "$@"
EOF

sudo chmod +x /usr/local/bin/git-llm
```

Now you can use:
```bash
git llm commit              # Calls git-llm commit
git llm changelog           # Calls git-llm changelog
```

### Recommended Git Workflow

With git aliases configured, your workflow becomes:

```bash
# Make changes
echo "console.log('Hello');" > app.js

# Stage changes
git add .

# Generate AI commit message (opens editor)
git llm commit

# Or commit directly
git llm commit --apply

# Generate changelog
git llm changelog

# Check configuration
git llm config get
```

## Requirements

- Python 3.12+
- Git
- At least one LLM provider API key (OpenAI, Anthropic, Google, or Azure OpenAI)
- **Optional**: Ollama for hybrid processing (local chunk processing)

## Troubleshooting

### Common Issues

**"No suitable editor found"**
- Set your preferred editor: `git-llm config set editor.preferred_editor vi`
- Or set git editor: `git config --global core.editor vi`

**"No staged changes found"**
- Stage your changes first: `git add .`

**"API Error: Invalid API key"**
- Check your API key configuration: `git-llm config get`
- Ensure the key is correctly set: `git-llm config set llm.api_keys.openai sk-your-key`

**"No commits found in range"**
- Make sure you have commits in the specified range
- Check git log: `git log --oneline`

**"Ollama not available, using main LLM for chunks"**
- Make sure Ollama is installed and running: `ollama serve`
- Check Ollama is accessible: `curl http://localhost:11434/api/version`
- Verify the model is pulled: `ollama list`
- Pull the model if needed: `ollama pull llama3:8b`

**"Processing is slower than expected"**
- For large diffs, enable hybrid mode with Ollama for faster chunk processing
- Check your `chunking_threshold` setting - lower values use chunking sooner
- Use `--verbose` to see processing details and bottlenecks

**"Chunk processing failed"**
- If using Ollama, ensure sufficient system resources (RAM)
- Try a smaller model like `llama3:8b` instead of larger models
- Check Ollama logs: `ollama logs`
