A hatch virtual environment plugin to lock dependencies with pip-deepfreeze.

Installation

hatch-pip-deepfreeze must be installed in the same environment as hatch itself.

If hatch has been installed with pipx:

pipx runpip hatch install hatch-pip-deepfreeze

If hatch has been installed with pip in the user environment:

pip install --user hatch-pip-deepfreeze

Usage

In the tool.hatch.envs.{name} section, add type = "pip-deepfreeze". Such environments behave similarly to the standard hatch virtual environments, except the installation and synchronization is performed using pip-deepfreeze sync.

This will automatically generate locked dependencies in requirements.txt, and uninstall unneeded dependencies after removing them from pyproject.toml. It also pins optional dependencies groups in requirements-{extra}.txt.

You can use the features to install project.optional-dependencies in environments.

Note that this pluging does not support per environment dependencies, because pip-deepfreeze works exclusively with project.optional-dependencies for that. Fortunately this is well supported by hatch.

As an example, you can adapt a pyproject.toml generated by hatch new like so:

Declare optional dependencies for test:

[project.optional-dependencies]
test = [
    "pytest",
    "pytest-cov",
]

Update the default environment section to remove dependencies and add features:

[tool.hatch.envs.default]
type = "pip-deepfreeze"
features = ["test"]

Use the usual hatch environment activation features such as hatch shell and notice pip-deepfreeze in action.
