Utility to find unused packages in requirements and to constrain package usage
A simple source code import checker that checks your project for whether you:
- Import and use everything in your requirements.txt file; and/or
- Import packages with specified frequencies using a constraint file (use to wean a project off of a dependency).
Install the latest stable version from PyPI using:
pip install important
Otherwise, to grab the latest version on master, use:
pip install git+https://github.com/cfournie/important.git
This works best when run from a virtualenv where your project’s requirements are installed (to translate requirements to module names).
This tool requires that it be installed with the same Python version as the source code that it’s analyzing and that the source code is syntactically correct.
Check for unused requirements using:
$ important -v --requirements requirements.txt . Parsed 52 imports in 8 files Error: Unused requirements or violated constraints found caniusepython3 (unused requirement)
Check for imports that are used too frequently (to prevent further usage of a requirement while you phase it out) using:
$ important -v --constraints constraints.txt . Parsed 52 imports in 8 files Error: Unused requirements or violated constraints found click<=1 (constraint violated by click==2)
Check for unused requirements but exclude test files using:
$ important -v --requirements requirements.txt --exclude **/test_*.py . Parsed 52 imports in 8 files Error: Unused requirements or violated constraints found caniusepython3 (unused requirement)
Ignore errors related to some of your requirements using:
$ important -v --requirements requirements.txt --ignore caniusepython3 . Parsed 52 imports in 8 files $ important -v --requirements requirements.txt --ignorefile ignored.txt . Parsed 52 imports in 8 files
Alternatively, you can configure important using a setup.cfg file in the current working directory, e.g.:
[important] requirements= requirements.txt constraints= constraints.txt ignore= Sphinx flake8 exclude= .git sourcecode=.
Then run using:
$ important -v Parsed 52 imports in 8 files
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
