zampy developer documentation

If you're looking for user documentation, go here.

Development install

# Create a virtual environment, e.g. with
python3 -m venv env

# activate virtual environment
source env/bin/activate

# make sure to have a recent version of pip and hatch
python3 -m pip install --upgrade pip hatch

# (from the project root directory)
# install s2spy as an editable package
python3 -m pip install --no-cache-dir --editable .
# install development dependencies
python3 -m pip install --no-cache-dir --editable .[dev]

Afterwards check that the install directory is present in the PATH environment variable.

Running the tests

Running tests has been configured using hatch, and can be started by running:

hatch run test

The second is to use tox, which can be installed separately (e.g. with pip install tox), i.e. not necessarily inside the virtual environment you use for installing zampy, but then builds the necessary virtual environments itself by simply running:

Test coverage

In addition to just running the tests to see if they pass, they can be used for coverage statistics, i.e. to determine how much of the package's code is actually executed during tests. Inside the package directory, run:

hatch run coverage

This runs tests and prints the results to the command line, as well as storing the result in a coverage.xml file (for analysis by, e.g. SonarCloud).

Running linters locally

For linting we will use flake8, black and isort. We additionally use mypy to check the type hints. All tools can simply be run by doing:

linter

hatch run lint

To easily comply with black and isort, you can also run:

hatch run format

This will apply the black and isort formatting, and then check the code style.

Generating the documentation

To generate the documentation, simply run the following command. This will also test the documentation code snippets. Note that you might need to install pandoc to be able to generate the documentation.

hatch run docs:build

The documentation will be in docs/_build/html.

Versioning

Bumping the version across all files is done with bump-my-version, e.g.

bumpversion bump major
bumpversion bump minor
bumpversion bump patch

Making a release

This section describes how to make a release in 3 parts: preparation, release and validation.

Preparation

  1. Update the (don't forget to update links at bottom of page)
  2. Verify that the information in CITATION.cff is correct, and that .zenodo.json contains equivalent data
  3. Make sure the version has been updated.
  4. Run the unit tests with hatch run test

Making the GitHub release

Make a release and tag on GitHub.com. This will:

  • trigger Zenodo into making a snapshot of your repository and sticking a DOI on it.
  • start a GitHub action that builds and uploads the new version to PyPI.

Validation

After making the release, you should check that:

  • The publishing action ran successfully, and that pip install zampy installs the new version.
