Autohooks

Library for managing and writing git hooks in Python

Why

Several outstanding libraries for managing and executing git hooks already exist. To name few: husky, lint-staged, precise-commits or pre-commit.

But either they need another interpreter besides python (like husky) or they are too ambiguous like (pre-commit). pre-commit is written in python but has support hooks written in all kind of languages. Also it maintains the dependencies by itself and doesn't install in the current environment.

Solution

Autohooks is a pure python library that installs a minimal executable git hook. If autohooks isn't installed in your current python path the hooks aren't executed. So autohooks is always opt-in by installing the package into your current development environment. It would be even possible to run different versions of autohooks by switching the environment.

Installation

For the installation of autohooks three steps are necessary:

1. Install the autohooks package into your current environment
2. Activate the git hooks
3. Configure the plugins to be run

Install autohooks python package

For installing the autohooks python package, using pipenv is highly recommended.

To install autohooks as a development dependency run

pipenv install --dev autohooks

Alternatively autohooks can be installed directly from GitHub

pipenv install --dev -e git+https://github.com/bjoernricks/autohooks#egg=autohooks

Activating the git hooks

If autohooks is installed from git or a source tarball, the git hooks should be activated automatically. The activation can be verified by running e.g. autohooks check.

Installing autohooks from a wheel package will NOT activate the git commit hooks.

To manually activate the git hooks you can run

pipenv run autohooks activate

Configure plugins to be run

To actually run an action on git hooks, autohooks plugins have to be configured. Autohooks uses the pyproject.toml file specified in PEP518 for its configuration. Adding a [tool.autohooks] section allows to set python modules to be run on a specific git hook.

Example pyproject.toml:

[build-system]
requires = ["setuptools", "wheel"]

[tool.autohooks]
pre-commit = ["autohooks.plugins.black"]

Plugins

• Python code formatting via black

• Python code linting via pylint
