Depwise is pre-alpha software. It is not ready.
A fast, comprehensive dependency analyzer for Python projects that detects unused, missing, and optional dependencies across multiple environments. Supports requirements.txt, conda, pyproject.toml, pixi, and setup.py without requiring installation. Features intelligent pattern detection for optional dependencies, synthetic fast-pass analysis, and validation against actual environments. Designed for pre-commit hooks and CI/CD pipelines.
To check a project, you can use the depwise check command.
# Check a project using a pyproject.toml file
depwise check --project <path-to-pyproject.toml> <path to source code>
# Check a project using a requirements.txt file. Explictly treat the path as a module and not recursively check subdirectories.
depwise check --requirements <path-to-requirements.txt> --module <path to source code>
# Check a project using a conda environment file. Explictly treat the path as a project and recursively check subdirectories.
depwise check --condayml <path-to-environment.yml> --project <path to source code>To check source code in the currently active Python environment, you can use the depwise check command with the --current flag.
depwise check --current <path to source code>To check a wheel, sdist, or conda package, you can use the depwise check-package command.
depwise check-package <path-to-package>To make it easier to test multiple environments, Depwise can be configured using a depwise.toml or pyproject.toml (using the [tool.depwise] prefix) file.
