This is highly recommended unless you are experienced
with cross-platform Python packaging.

Development

For changes to the plugin, a Python virtual environment is recommended. The development requirements can be sourced from the core repository:

python3 -m venv env
source env/bin/activate
pip install -e . -e src/ \
  -r https://raw.githubusercontent.com/aws-cloudformation/aws-cloudformation-rpdk/master/requirements.txt
pre-commit install

Linting and running unit tests is done via pre-commit, and so is performed automatically on commit. The continuous integration also runs these checks. Manual options are available so you don't have to commit):

# run all hooks on all files, mirrors what the CI runs
pre-commit run --all-files
# run unit tests only. can also be used for other hooks, e.g. black, flake8, pylint-local
pre-commit run pytest-local
