Development

First setup your virtual environment (or ignore if you already have it):

python -m venv .venv
source .venv/bin/activate

Then install required dependencies:

pip install -U pip setuptools
pip install build pre-commit pytest wheel mypy~=1.4 black~=23.7 pylint~=2.17 ruff==0.0.282
pre-commit install

Then install this extension in editable mode, simply change to this directory, and run:

pip install -e .

You could also use make targets such as:

make install    # for installation
make dev        # for editable install
make lint       # run linters and formatters
make tests      # for running tests
make build      # for source and wheel distribution packages
make clean      # to clean up autogenerated files

Contributing

Pull requests are welcome. To make a PR, first fork the repo, make your proposed changes on the main branch, and open a PR from your fork. If it passes tests and is accepted after review, it will be merged in.

Code style

Formatting

All code should be formatted using black, with default options. This is checked on the CI.

Type annotation

On the CI, mypy is used as a static type checker and all submissions must pass its checks. You should therefore run mypy locally on any changed files before submitting a PR. Because of the way extension modules embed themselves into the pytket namespace this is a little complicated, but it should be sufficient to run the script ./mypy-check (passing as a single argument the root directory of the module to test).

Linting

We use ruff and pylint on the CI to check compliance with a set of style requirements (listed in ruff.toml and .pylintrc). You should run pylint over any changed files before submitting a PR, to catch any issues.

An easy way to meet all formatting and linting requirements is to issue pre-commit run --all-files or make lint before sending a PR.

Tests

To run the tests:

1. cd into the tests directory;
2. ensure you have installed pytest, hypothesis, and any modules listed in the test-requirements.txt file (all via pip);
3. run pytest.

When adding a new feature, please add a test for it. When fixing a bug, please add a test that demonstrates the fix.
