Contributing

Contributions to emeis are very welcome! Best have a look at the open issues and open a GitHub pull request. See instructions below how to setup development environment. Before writing any code, best discuss your proposed change in a GitHub issue to see if the proposed change makes sense for the project.

Setup development environment

Clone

To work on emeis you first need to clone

git clone https://github.com/projectcaluma/emeis.git
cd emeis

Open Shell

Once it is cloned you can easily open a shell in the docker container to open an development environment.

# needed for permission handling
# only needs to be run once
echo UID=$UID > .env
# open shell
docker-compose run --rm emeis bash

Testing

Once you have shelled in docker container as described above you can use common python tooling for formatting, linting, testing etc.

# linting
flake8
# format code
black .
# running tests
pytest
# create migrations
./manage.py makemigrations
# install debugger or other temporary dependencies
pip install --user pdbpp

Writing of code can still happen outside the docker container of course.

Install new requirements

In case you're adding new requirements you simply need to build the docker container again for those to be installed and re-open shell.

docker-compose build --pull

Setup pre commit

Pre commit hooks is an additional option instead of executing checks in your editor of choice.

First create a virtualenv with the tool of your choice before running below commands:

pip install pre-commit
pip install -r requiements-dev.txt -U
pre-commit install
