dependency-groups
A tool for resolving PEP 735 Dependency Group data
Description
Dependency Groups ================= An implementation of Dependency Groups (`PEP 735 <https://peps.python.org/pep-0735/>`_). This is a library which is able to parse dependency groups, following includes, and provide that data as output. Interfaces ---------- ``dependency-groups`` provides the following: - A ``DependencyGroupResolver`` which implements efficient resolution of dependency groups - A ``resolve()`` function which converts a dependency group name to a list of strings (powered by the resolver) - Three CLI commands: - ``python -m dependency_groups GROUPNAME`` prints a dependency group's contents - ``lint-dependency-groups`` loads all dependency groups to check for correctness - ``pip-install-dependency-groups GROUPNAME...`` wraps a ``pip`` invocation to install the contents of a dependency group - A pre-commit hooks which runs ``lint-dependency-groups`` Documentation ------------- Full documentation is available on `the Dependency Groups doc site <https://dependency-groups.readthedocs.io/>`_.
Release History
| Version | Changes | Urgency | Date |
|---|---|---|---|
| 1.3.2 | - Add support for Python 3.14 and 3.15 - Remove support for Python 3.8 - Correct the type of the ``dependency_groups`` parameter to ``resolve()``, ``resolve_all()``, and ``DependencyGroupsResolver()``. - Raise a clear ``TypeError`` when an ``include-group`` value is not a string (was a cryptic ``TypeError`` from name normalization), and accept any ``Mapping`` for include items, not only ``dict``. - Fix a bug in which ``pip-install-dependency-groups`` failed when the resolved groups were empty.

| 1.3.0 | - Bugfix: raise a `TypeError` on non-list groups (was `ValueError`). Thanks @henryiii! - Several improvements to the CLI interfaces! Thanks @henryiii! - Add support for a `cli` extra, as in `pip install "dependency-groups[cli]"`, which ensures that `tomli` is present on older Pythons. - Add support for `dependency-groups` as an entrypoint, as an alias of `python -m dependency_groups`. - The `dependency-groups` command now supports a `--list` flag to list groups instead of resolving the | Low | 11/1/2024 |
