Development

To get started with working on the codebase, use the following steps prepare your local environment:

# clone the github repo and navigate into the folder
git clone https://github.com/ApeWorX/ape-vyper.git
cd ape-vyper

# create and load a virtual environment
python3 -m venv venv
source venv/bin/activate

# install ape-vyper into the virtual environment
python setup.py install

# install the developer dependencies (-e is interactive mode)
pip install -e .'[dev]'

Pre-Commit Hooks

We use pre-commit hooks to simplify linting and ensure consistent formatting among contributors. Use of pre-commit is not a requirement, but is highly recommended.

Install pre-commit locally from the root folder:

pip install pre-commit
pre-commit install

Committing will now automatically run the local hooks and ensure that your commit passes all lint checks.

Pull Requests

Pull requests are welcomed! Please adhere to the following:

  • Ensure your pull request passes our linting checks
  • Include test cases for any new functionality
  • Include any relevant documentation updates

It's a good idea to make pull requests early on. A pull request represents the start of a discussion, and doesn't necessarily need to be the final, finished submission.

If you are opening a work-in-progress pull request to verify that it passes CI tests, please consider marking it as a draft.

Join the ApeWorX Discord if you have any questions.

Testing

By default, the test suite will use a new, temporary path for the Vyper compiler installations. This ensures that the tests always run from a clean slate without any relying on existing installations.

If you wish to use your existing ~/.vvm installations instead, you must set the environment variable APE_VYPER_USE_SYSTEM_VYPER=1.

This will ensure that vvm's default path will be used, but any compilers installed as part of the tests will not be removed after tests have completed.
