Date/time helper functions used by various Seantis packages.

Project description

PyPI version Python versions Tests pre-commit

Date/time helper functions used by various Seantis packages.

There are projects like Arrow or Delorean which provide ways to work with timezones without having to think about it too much.

Seantis doesn’t use them because we want to reason about these things, to ensure they are correct, and partly because of self-loathing.

Adding another layer makes this reasoning harder.

Run the Tests

Install tox and run it:

pip install tox

Limit the tests to a specific python version:

tox -e py37


Sedate follows PEP8 as close as possible. To test for it run:

tox -e lint

Sedate uses Semantic Versioning


Setup your local development environment:

python3.8 -m venv venv
source venv/bin/activate
pip install .[dev]
pre-commit install
