Dev environment setup

We use some tools as part of our development workflow which you'll need to install into your host environment:

• poetry for packaging and dependency management
• poethepoet for running development tasks
• commitizen for writing git commits easily

Or you can use to start hacking with one click!

Get Started!

Ready to contribute? Here's how to set up the project for local development.

1. Fork the copier repo on GitHub.

2. Clone your fork locally:

   git clone git@github.com:my-user/copier.git
   cd copier
   

3. Use poetry to setup a development environment

   # Tell Poetry to create the virtualenv in the project directory
   poetry config virtualenvs.in-project true --local
   
   # Create a virtualenv with all dependencies from pyproject.toml
   poetry install -E docs
   
   # Install development helper tools
   poetry run pre-commit install -t pre-commit -t commit-msg
   
   # Create a new shell with the virtualenv activated
   poetry shell
   

4. Create a branch for local development:

   git checkout -b name-of-your-bugfix-or-feature
   

   Now you can make your changes locally.

5. When you're done making changes, check that your changes pass all tests

   poe test
   poe lint
   

   To have multiple Python versions on the same machine for running tox, I recommend using pyenv (do not confuse it with pipenv,).

6. Commit your changes and push your branch to GitHub:

   git add .
   cz commit  # use `git commit` if you prefer, but this helps
   git push origin name-of-your-bugfix-or-feature
   

7. Submit a pull request through the GitHub website.

Pull Request Guidelines

Before you submit a pull request, check that it meets these guidelines:

1. The pull request has code, it should include tests.
2. Check that all checks pass on GitHub CI

Tips

To run a subset of tests:

poe test tests/the-tests-file.py
