We're so glad you're thinking about contributing to this open source project! If you're unsure or afraid of anything, just ask or submit the issue or pull request anyway. The worst that can happen is that you'll be politely asked to change something. We appreciate any sort of contribution, and don't want a wall of rules to get in the way of that.

Before contributing, we encourage you to read our CONTRIBUTING policy (you are here), our LICENSE, and our README, all of which should be in this repository.


If you want to report a bug or request a new feature, the most direct method is to create an issue in this repository. We recommend that you first search through existing issues (both open and closed) to check if your particular issue has already been reported. If it has then you might want to add a comment to the existing issue. If it hasn't then feel free to create a new one.

Pull requests

If you choose to submit a pull request, you will notice that our continuous integration (CI) system runs a fairly extensive set of linters and syntax checkers. Your pull request may fail these checks, and that's OK. If you want you can stop there and wait for us to make the necessary corrections to ensure your code passes the CI checks.

If you want to make the changes yourself, or if you want to become a regular contributor, then you will want to set up pre-commit on your local machine. Once you do that, the CI checks will run locally before you even write your commit message. This speeds up your development cycle considerably.

Setting up pre-commit

There are a few ways to do this, but we prefer to use pyenv and pyenv-virtualenv to create and manage a Python virtual environment specific to this project.

Installing and using pyenv and pyenv-virtualenv

On the Mac, installation is as simple as brew install pyenv pyenv-virtualenv and adding this to your profile:

eval "$(pyenv init -)"
eval "$(pyenv virtualenv-init -)"

For Linux (or on the Mac, if you don't want to use brew) you can use pyenv/pyenv-installer to install the necessary tools. When you are finished you will need to add the same two lines above to your profile.

For a list of Python versions that are already installed and ready to use with pyenv, use the command pyenv versions. To see a list of the Python versions available to be installed and used with pyenv use the command pyenv install --list. You can read more here about the many things that pyenv can do. See here for the additional capabilities that pyenv-virtualenv adds to the pyenv command.

Creating the Python virtual environment

Once pyenv and pyenv-virtualenv are installed on your system, you can create and configure the Python virtual environment with these commands:

cd skeleton-generic
pyenv virtualenv <python_version_to_use> skeleton-generic
pyenv local skeleton-generic
pip install -r requirements-dev.txt

Installing the pre-commit hook

Now setting up pre-commit is as simple as:

pre-commit install

At this point the pre-commit checks will run against any files that you attempt to commit. If you want to run the checks against the entire repo, just execute pre-commit run --all-files.
