"""Tox plugin for installing environments using Poetry
This plugin makes use of the ``tox_testenv_install_deps`` Tox plugin hook to augment the default
installation functionality to install dependencies from the Poetry lockfile for the project. It
does this by using ``poetry`` to read in the lockfile, identify necessary dependencies, and then
use Poetry's ``PipInstaller`` class to install those packages into the Tox environment.
Quick definition of terminology:
* "project package" - the package that Tox is testing, usually the one the current project is
is developing; definitionally, this is the package that is built by Tox in the ``.package`` env.
* "project package dependency" or "project dependency" - a dependency required by the project
package for installation; i.e. a package that would be installed when running
``pip install <project package>``.
* "environment dependency" - a dependency specified for a given testenv in the Tox configuration.
* "locked dependency" - a package that is present in the Poetry lockfile and will be installed
according to the metadata in the lockfile.
* "unlocked dependency" - a package that is either not present in the Poetry lockfile or is not
specified to be installed according to the metadata in the lockfile.
* "transiety dependency" - a package not explicitly specified for installation, but required by a
package that is explicitly specified.
