## Installation

### From PyPI

```bash
pip install changelog-checker
```

## Quick Start

The most common usage is to pipe package manager output directly to changelog-checker:

```bash
# Update dependencies and check changelogs
uv sync -U 2>&1 | changelog-checker

# Or save output to file first
uv sync -U &> updates.txt
changelog-checker -i updates.txt

# or get html report
changelog-checker -i updates.txt -f html -o report.html
```

## Usage

### Basic Usage

```bash
# Pipe uv output directly
uv sync -U 2>&1 | changelog-checker

# Read from file
changelog-checker --input-file updates.txt

# Enable verbose output
changelog-checker -v --input-file updates.txt

# Use GitHub token for higher rate limits
export GITHUB_TOKEN=your_token_here
uv sync -U 2>&1 | changelog-checker
```

### Command Line Options

```bash
Options:
  -i, --input-file FILENAME       Read input from file instead of stdin
  -p, --parser [uv]               Parser type to use (default: uv)

  -t, --github-token TEXT         GitHub API token for authentication (can
                                  also use GITHUB_TOKEN env var)
  -f, --output-format [terminal|html]
                                  Output format: terminal (rich console) or

## Supported Package Managers

Currently supported:

- **uv**: Python package manager

## How It Works

1. **Parse Input**: Analyzes package manager output to identify updated packages
2. **Find Packages**: Searches for package information on PyPI and GitHub
3. **Fetch Changelogs**: Retrieves changelog information from multiple sources:
   - GitHub releases API
   - Repository changelog files (CHANGELOG.md, HISTORY.md, etc.)
   - PyPI project descriptions
4. **Parse & Format**: Processes changelog content and presents it in a readable format

## Configuration

### GitHub Token

For better rate limits and access to private repositories, set up a GitHub token:

1. Go to GitHub Settings → Developer settings → Personal access tokens
2. Generate a new token with `public_repo` scope
3. Set the environment variable:

   ```bash
   export GITHUB_TOKEN=your_token_here
   ```

## Development

### Setup

```bash
git clone https://github.com/MrNaif2018/changelog-checker.git
cd changelog-checker
uv sync
```

### Running Tests

```bash
uv run task test
```

### Code Quality

```bash
# Run linting
uv run task lint
# Type checking
uv run task lint_types

# Run all checks
uv run task ci
```
