GitHub Workflow

Git

There are many great tutorials on git out there, so this one won’t cover the basics. Check out e.g.:

GitHub Flow

In general, we use the GitHub flow:

Note

If you want to build your commits on CircleCI or start a discussion before your branch is ready for review, you can also create a draft pull request.

Rebasing

In extension to the GitHub flow, we use rebasing in two situations:

1. Update feature branch

You want to merge recent changes of the develop branch into your current feature branch, e.g. because there are conflicts that prevent your branch from being merged:

# fetch upstream changes of origin/develop
git fetch --all
# rebase your feature branch onto the current upstream develop branch
git rebase origin/develop
# if the rebase cannot be performed automatically, resolve the conflicts and continue
git rebase --continue
# if more conflicts pop up, repeat the previous step until the rebase is finished
# force-push your changes
git push --force-with-lease

2. Clean up git history

You have many small commits which clutter the git history, or want to combine rearrange commits on your current feature branch:

# fetch upstream changes of origin/develop
git fetch --all
# interactive rebase starting at the commit where your current branch was forked from develop
git rebase --interactive $(git merge-base --fork-point origin/develop $(git rev-parse --abbrev-ref HEAD))
# sort and modify your commits as you want
# exit the editor and save
# if the rebase cannot be performed automatically, resolve the conflicts and continue
git rebase --continue
# if more conflicts pop up, repeat the previous step until the rebase is finished
# force-push your changes
git push --force-with-lease

Warning

Don’t do git pull between rebasing and pushing. This will result in duplicate commits. You have to overwrite the upstream branch with your rebased commits by using the option --force-with-lease.
Only force-push to your own feature branches!

Note

If you want to pull your rebased branch feature from another machine, use the following:

git fetch --all
git reset --hard origin/feature

Pre-commit Hooks

Pre-commit hooks are commands which are run every time a commit is created to check whether the committed changes comply with the repository’s standards. All hooks for this repository are defined in .pre-commit-config.yaml. At the moment, the following hooks are configured:

shellcheck: a static analysis tool for shell scripts (see: Shellcheck and ShellCheck wiki)
ruff: A formatter and linter which applies automatic code formatting to Python files (see Ruff)
prettier: A formatter which applies automatic code formatting to CSS/JS files (see Prettier)
djlint: A formatter which applies automatic code formatting to Django HTML templates (see DjLint)
translations A script which checks whether the translation file is up-to-date (see: Internationalization (i18n) and Translations)

Activation

To activate the pre-commit hooks, either install the CMS with the command:

./tools/install.sh --pre-commit

or execute:

pre-commit install

manually after installing.

Deactivation

To deactivate a specific hook (in this example the translations-hook), use:

SKIP=translations git commit

To deactivate all pre-commit hooks for a specific commit, use:

git commit --no-verify

If you want to deactivate pre-commit hooks for this repository entirely, use:

pre-commit uninstall
