Contributing to Kalamine

Setup

After checking out the repository, you can install kalamine and its development dependencies like this:

python3 -m pip install --user .[dev]

Which is the equivalent of:

python3 -m pip install --user -e .
python3 -m pip install --user build ruff pytest mypy types-PyYAML pre-commit

There’s also a Makefile recipe for that:

make dev

We rely on ruff for that, with the isort rule enabled:

ruff format kalamine
ruff check --fix kalamine

Alternative:

make format

We rely on ruff and mypy for that, with their default configurations:

ruff format --check kalamine
ruff check kalamine
mypy kalamine

Alternative:

make lint

Many linting errors can be fixed automatically:

ruff check --fix kalamine

We rely on pytest for that, but the sample layouts must be built by kalamine first:

python3 -m kalamine.cli make layouts/*.toml
pytest

Alternative:

make test

You may ensure manually that your commit will pass the Github CI (continuous integration) with:

make

But setting up a git pre-commit hook is strongly recommended. Just create an executable .git/hooks/pre-commit file containing:

#!/bin/sh
make

This is asking git to run the above command before any commit is created, and to abort the commit if it fails.
