An implementation of Dependency Groups (PEP 735).

This is a library which is able to parse dependency groups, following includes, and provide that data as output.

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

Full documentation is available on the Dependency Groups doc site.
