For Developers

Environment set up

From this directory (./diffify-lib/ in the repository), to load the developer environment for this package:

• Install poetry: pip install poetry
• Install the 'dev' dependencies: poetry install

Then activate the environment:

poetry shell

From here you can open VS code, and have the environment preloaded.

Tests

Unit tests can be run without further set up:

pytest tests/unit

To run the integration tests, you'll need some environment variables defined:

• S3_KEY_DEV
• S3_SECRET_DEV
• S3_BUCKET_DEV
• S3_URL_DEV

Contact the diffify devs if you need these secrets. The simplest way to use these secrets locally is to store them in a file .dev.env (do not add this file to version control) and load that file into your working environment before running the tests:

env $(cat .dev.env) pytest tests

Note that the integration tests will be run in GitLab's CI runners, so you may not need to have access to these secrets.

Version numbers

Any pull request that modifies the source code should have an associated version bump to the package. When this happens you should change the version in two places:

• [tool.poetry] section of pyproject.toml
• __version__ declaration in diffify_lib/__init__.py

A simple way to keep the version numbers in sync is to use:

poetry version patch|minor|major

This requires that poetry-bumpversion is installed alongside poetry.

Pre-commit hooks

A pre-commit suite is defined in the root of this repository. You are strongly advised to use these hooks during development. To register the hooks with your local copy of the repository, run the following (from the repo-root):

# Install pre-commit itself
pip install pre-commit
# Install the hooks that pre-commit runs
pre-commit install

Now, pre-commit will run on your code at every commit, maintaining the style and quality of the code.
