A Python tool to check your requirements.txt file for package updates, with optional file caching for better performance.

• Check for available updates in your requirements.txt file
• Show update severity (major/minor/patch)
• Display package homepages and changelogs when available
• Optional file caching for faster repeated checks
• Support for comments and inline comments in requirements.txt
• Ignores pre-release versions (alpha, beta, release candidates)

Install from PyPI:

pip install req-update-check

Or install from the repo directly:

pip install git+https://github.com/ontherivt/req-update-check.git

Or install from source:

git clone https://github.com/ontherivt/req-update-check.git
cd req-update-check
pip install -e .

Basic usage:

req-update-check requirements.txt

req-update-check [-h] [--no-cache] [--cache-dir CACHE_DIR] requirements_file

Arguments:

• requirements_file: Path to your requirements.txt file

Options:

• --no-cache: Disable file caching
• --cache-dir: Custom cache directory (default: ~/.req-update-check-cache)

File caching enabled
The following packages need to be updated:

requests: 2.28.0 -> 2.31.0 [minor]
    Pypi page: https://pypi.python.org/project/requests/
    Homepage: https://requests.readthedocs.io
    Changelog: https://requests.readthedocs.io/en/latest/community/updates/#release-history

redis: 4.5.0 -> 5.0.1 [major]
    Pypi page: https://pypi.python.org/project/redis/
    Homepage: https://github.com/redis/redis-py
    Changelog: https://github.com/redis/redis-py/blob/master/CHANGES

The tool supports file caching to improve performance when checking multiple times. You can configure the cache storage:

req-update-check --cache-dir ~/.your-cache-dir requirements.txt

The tool supports requirements.txt files with the following formats:

package==1.2.3
package == 1.2.3  # with spaces
package==1.2.3  # with inline comments
# Full line comments

Note: Currently only supports exact version specifiers (==). Support for other specifiers (like >=, ~=) is planned for future releases.

You can also use req-update-check as a Python library:

from req_update_check import Requirements

# Without file cache
req = Requirements('requirements.txt', allow_cache=False)
req.check_packages()
req.report()

# With file cache defaults
req = Requirements('requirements.txt')
req.check_packages()
req.report()

To set up for development:

1. Clone the repository
2. Create a virtual environment: python -m venv venv
3. Activate the virtual environment: source venv/bin/activate (Unix) or venv\Scripts\activate (Windows)
4. Install development dependencies: pip install -e ".[dev]"

To run tests:

1. python -m unittest
