## 📦 Installation

### From Source

```bash
git clone https://github.com/jondot/bhgrep.git
cd bhgrep
cargo build --release
```

The binary will be at `target/release/bhgrep`. You can add it to your PATH:

```bash
sudo cp target/release/bhgrep /usr/local/bin/
```

### Using Cargo

```bash
cargo install bhgrep
```

## 🚀 Quick Start

### Interactive Mode (Default)

Simply run `bhgrep` without arguments to enter interactive mode:

```bash
bhgrep
```

**Keyboard shortcuts:**
- Type to search
- `Enter`: Open selected URL in browser
- `y`: Copy URL to clipboard
- `Esc` or `q`: Quit
- `↑/↓`: Navigate results
- `Ctrl+U`: Clear search

### CLI Mode

Search with a query:

```bash
bhgrep --query "rust programming"
```

## 📖 Usage

### Basic Examples

```bash
# Search and output as JSON
bhgrep -q "rust" --format json

# Get only URLs (perfect for scripting)
bhgrep -q "tutorial" --format url-only

# Open first result in browser
bhgrep -q "github" --open

# Copy first result URL to clipboard
bhgrep -q "stackoverflow" --copy

# Search only Chrome history
bhgrep -q "documentation" --browser chrome

# Use regex for pattern matching
bhgrep --mode regex -q "github\.com/.*/.*" --format url-only
```

### Advanced Examples

```bash
# Find all GitHub repos you've visited
bhgrep -q "github.com" --format url-only | grep -E "github\.com/[^/]+/[^/]+" | sort -u

# Export full history as JSON for analysis
bhgrep -q "" --format json --limit 10000 > history.json

# Search with custom limit
bhgrep -q "documentation" --limit 50

# Use database mode for faster startup (slower queries)
bhgrep -q "search term" --mode db
```

### Output Formats

- **`plain`** (default): Human-readable format with title, URL, and metadata
- **`json`**: JSON format perfect for scripting and automation
- **`url-only`**: Just URLs, one per line

## 🎯 Use Cases

### For Developers

```bash
# Quick alias for documentation lookup
alias doc='bhgrep -q "$1" --format url-only --open'

# Find all Stack Overflow answers you've visited
bhgrep -q "stackoverflow.com" --format url-only

# Collect resources for a project
bhgrep -q "myproject" --format json | jq '.[] | .url' > resources.txt
```

### For Security Researchers

```bash
# Export sensitive history for analysis
bhgrep -q "token=" --format json --limit 50000 > full_history.json

# Find visits to specific domains
bhgrep --mode regex -q "example\.com" --format json

# Timeline analysis
bhgrep -q "target" --format json | jq -r '.[] | "\(.last_visit) | \(.url)"' | sort
```

## 🌐 Supported Browsers

## 🙏 Acknowledgments

- Built with [Rust](https://www.rust-lang.org/)
- Uses [ratatui](https://github.com/ratatui-org/ratatui) for the TUI
- Uses [fuzzy-matcher](https://github.com/lotabout/fuzzy-matcher) for fuzzy search
- Inspired by tools like `fzf` and `ripgrep`

## 📊 Performance

bhgrep is optimized for speed:

- **Fuzzy mode**: Fast queries after initial load (~100ms for 10k entries)
- **DB mode**: Fast startup, queries database directly
- **Smart caching**: Browser databases are cached to avoid repeated file operations
- **Efficient scoring**: Only clones entries that make it to final results

## 🐛 Troubleshooting

### No results found

- Make sure you have browser history in supported browsers
- Try a broader search query
- Check that browsers are installed and have history

### Permission errors (macOS)

- Grant Full Disk Access to Terminal/iTerm in System Preferences
- Safari requires Full Disk Access to read its history database

### Slow performance

- Use `--mode db` for faster startup if you have large history
- Reduce `--limit` for faster results
- Consider using `--browser` to search only specific browsers
