Development

If you’d like to develop welly, this page should help you get started.

Installation

You can install this package with pip. The dev option will install the packages you need for testing and building the documentation.

pip install welly[dev]

Contributing

If you’d like to contribute pull requests back to the main welly project, please see CONTRIBUTING.md.

Testing

You can run the tests (requires pytest and pytest-cov) with

python run_tests.py

Most of the tests are doctest tests, which are contained in the docstrings of this package’s functions. It is also possible to add test files to the tests folder in the normal way.

Building the package

This repo uses PEP 517-style packaging. Read more about this and about Python packaging in general.

Building the project requires build, so first:

python -m pip install build

Then to build welly locally:

python -m build

This builds both .tar.gz and .whl files, either of which you can install with pip.

Building the docs

You can build the docs with the following commands:

cd docs
make html

Don’t just run sphinx-build manually: there is other stuff happening in the Makefile.

There is a continuous integration script to update the docs on published releases.

Continuous integration

This repo has two GitHub ‘workflows’ or ‘actions’:

• Push to main: Run all tests on all version of Python. This is the Build and test workflow.

• Publish a new release: Build and upload to PyPI. This is the Publish to PyPI workflow. Publish using the GitHub interface, for example (read more).
