Installation

From PyPI

pip install changelog-checker

Quick Start

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

# 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

# or use with (uv) pip to check changelogs of pinned dependencies
uv pip list --outdated | changelog-checker -p pip

Usage

Basic Usage

# 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

HTML reports

You can also generate HTML reports for later viewing:

changelog-checker -i updates.txt -f html -o report.html

Supported Package Managers

Currently supported:

• uv: Python package manager
• pip: Pip (only "list --outdated")

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:

   export GITHUB_TOKEN=your_token_here
