The pre-commit hooks in this repository help me maintain my own projects.
Enforces that the tool.poetry.dependencies.python value matches across pyproject.toml files in a given repository.
By default, only pyproject.toml files in a requirements/ subdirectory are checked. This can be customized by setting args in the .pre-commit.hooks.yaml configuration:
- id: "enforce-consistent-pyproject-toml-python-version-requirements"
args: ["test-requirements", "docs-requirements"]Poetry requires that all dependencies in all dependency groups must be internally consistent, but I typically don't want my testing dependencies to affect my package dependencies. (For example, the dependencies for static type analysis and documentation builds don't need to be internally consistent with the project requirements.) To support independent dependency resolution, I currently create separate pyproject.toml files, have Poetry resolve the dependencies, and export the requirements to pip-installable text files.
To help ensure that the secondary pyproject.toml files' Python requirements stay maintained, this hook verifies that the Python requirements (like ">=3.8") match across all files.
