+# All of the pre-commit hooks here actually use the `pytyhon` pre-commit language

-## Installation

-Add the plugin as a development dependency of a Poetry project:
+## Introduction

-```
-~ $: poetry add tox-poetry-installer --dev
+This is a plugin to unify two great projects in the Python ecosystem: the
+[Tox](https://tox.readthedocs.io/en/latest/) automation project and the
+[Poetry](https://python-poetry.org) project/dependency manager. Specifically it allows
+the repeatable dependency resolution and installation tools that Poetry uses to benefit
+the isolated environments that Tox uses to run automated tests. The motivation to write
+this plugin came from a need for a single source of truth for the versions of all
+packages that should be installed to an environment.
+
+When in use this plugin will allow a Tox environment to install its required
+dependencies using the versions specified in the Poetry lockfile. This eliminates
+needing to specify package versions in multiple places as well as ensures that the Tox
+environment has the exact same versions of a given package as the Poetry environment.
+This reduces (or hopefully eliminates) hard to debug problems caused by subtle
+differences in the dependency graph of the active development environment (the one managed
+by Poetry) and the automated test environment(s) created by Tox.
+
+To learn more about the problems this plugin aims to solve jump ahead to
+[What problems does this solve?](#why-would-i-use-this).
+Otherwise keep reading to get started.
+
+### Install
+
+The recommended way to install the plugin is to add it to a project's `pyproject.toml`
+and lockfile using Poetry:
+
+```bash
+poetry add tox-poetry-installer[poetry] --dev
 ```

-Confirm that the plugin is installed, and Tox recognizes it, by checking the Tox version:
+**WARNING:** The below installation methods are vulnerable to the
+[transient dependency issues this plugin aims to avoid](#why-would-i-use-this). It is
+always recommended to install dependencies using Poetry whenever possible.
+
+The plugin can also be installed with pip directly, though it is recommended to always
+install to a virtual environment and pin to a specific version:
+
+```bash
+source my-venv/bi/activate
+pip install tox-poetry-installer[poetry] == 0.6.0
+```
+
+The plugin can also be installed using the Tox
+[`requires`]((https://tox.readthedocs.io/en/latest/config.html#conf-requires))
+configuration option. Note however that dependencies installed via the `requires` option
+are not handled by the plugin and will be installed the same way as a `pip install ...`
+above. For this reason it is also recommended to always pin to a specific version when
+using this installation method:
+
+```ini
+# tox.ini
+[tox]
+requires
+    tox-poetry-installer[poetry] == 0.6.0
+```
+
+Check that the plugin is registered by checking the Tox version:

 ```
 ~ $: poetry run tox --version
 3.20.0 imported from .venv/lib64/python3.8/site-packages/tox/__init__.py
 registered plugins:
-    tox-poetry-installer-0.2.2 at .venv/lib64/python3.8/site-packages/tox_poetry_installer.py
+    tox-poetry-installer-0.6.0 at .venv/lib64/python3.8/site-packages/tox_poetry_installer.py
 ```

-If using Pip, ensure that the plugin is installed to the same environment as Tox:
+**NOTE:** Installing the `tox-poetry-installer[poetry]` extra will add the `poetry`
+package as a managed environment dependency which can cause problems when the Poetry
+installation is externally managed (such as in a CI or container environment). See
+[Advanced Usage](#installing-alongside-an-existing-poetry-installation) for more
+information on this use case.

-```
+### Quick Start

+Before making any changes to `tox.ini` the project is already benefiting from having
+the plugin installed: all dependencies of the root project package are installed using
+the Poetry backend to all Tox environments that install the root package without any
+configuration changes.

-## Quick Start
-
-To require a Tox environment install all it's dependencies from the Poetry lockfile, add the
-`require_locked_deps = true` option to the environment configuration and remove all version
-specifiers from the dependency list. The versions to install will be taken from the lockfile
-directly:
+To add dependencies from the lockfile to a Tox environment, add the option
+[`locked_deps`](#locked_deps) to the environment configuration and list names of
+dependencies (with no version specifier) under it:

 ```ini
 [testenv]
-description = Run the tests
-require_locked_deps = true
-deps =
-    pytest
-    pytest-cov
+description = Some very cool tests
+locked_deps =
    black
    pylint
    mypy
 commands = ...
 ```

-To require specific dependencies be installed from the Poetry lockfile, and let the rest be
-installed using the default Tox installation backend, add the suffix `@poetry` to the dependencies.
-In the example below the `pytest`, `pytest-cov`, and `black` dependencies will be installed from
-the lockfile while `pylint` and `mypy` will be installed using the versions specified here:
+The standard [`deps`](https://tox.readthedocs.io/en/latest/config.html#conf-deps) option
+can be used in parallel with the `locked_deps` option to install unlocked dependencies
+(dependencies not in the lockfile) alongside locked dependencies:

 ```ini
 [testenv]
-description = Run the tests
-require_locked_deps = true
+description = Some very cool tests
+locked_deps =
+    black
+    pylint
+    mypy
 deps =
-    pytest@poetry
-    pytest-cov@poetry
-    black@poetry
-    pylint >=2.5.0
-    mypy == 0.770
+    pytest == 6.1.1
+    pytest-cov >= 2.10, <2.11
 commands = ...
 ```

 Alternatively, to quickly install all Poetry dev-dependencies to a Tox environment, add the
-`install_dev_deps =  true` option to the environment configuration. This option can be used either
-with the `require_locked_deps = true` option or without it
-
-**Note:** Regardless of the settings outlined above, all dependencies of the project package (the
-one Tox is testing) will always be installed from the lockfile.
-
-
-## Usage Examples
-
-After installing the plugin to a project your Tox automation is already benefiting from the
-lockfile: when Tox installs your project package to one of your environments, all the dependencies
-of your project package will be installed using the versions specified in the lockfile. This
-happens automatically and requires no configuration changes.
-
-But what about the rest of your Tox environment dependencies?
-
-Let's use an example `tox.ini` file, below, that defines two environments: the main `testenv` for
-running the project tests and `testenv:check` for running some other helpful tools:
-
-```ini
-[tox]
-envlist = py37, static
-isolated_build = true
-
-[testenv]
-description = Run the tests
-deps =
-    pytest == 5.3.0
-commands = ...
-
-[testenv:check]
-description = Static formatting and quality enforcement
-deps =
-    pylint >=2.4.4,<2.6.0
-    mypy == 0.770
-    black --pre
-commands = ...
-```
-
-Let's focus on the `testenv:check` environment first. In this project there's no reason that any
-of these tools should be a different version than what a human developer is using when installing
-from the lockfile. We can require that these dependencies be installed from the lockfile by adding
-the option `require_locked_deps = true` to the environment config, but this will cause an error:
-
-```ini
-[testenv:check]
-description = Static formatting and quality enforcement
-require_locked_deps = true
-deps =
-    pylint >=2.4.4,<2.6.0
-    mypy == 0.770
-    black --pre
-commands = ...
-```
-
-Running Tox using this config gives us this error:
-
-```
-tox_poetry_installer.LockedDepVersionConflictError: Locked dependency 'pylint >=2.4.4,<2.6.0' cannot include version specifier
-```
-
-This is because we told the Tox environment to require all dependencies be locked, but then also
-specified a specific version constraint for Pylint. With the `require_locked_deps = true` setting
-Tox expects all dependencies to take their version from the lockfile, so when it gets conflicting
-information it errors. We can fix this by simply removing all version specifiers from the
-environment dependency list:
-
-```ini
-[testenv:check]
-description = Static formatting and quality enforcement
-require_locked_deps = true
-deps =
-    pylint
-    mypy
-    black
-commands = ...
-```
-
-Now all the dependencies will be installed from the lockfile. If Poetry updates the lockfile with
-a new version then that updated version will be automatically installed when the Tox environment is
-recreated.
-
-Now let's look at the `testenv` environment. Let's make the same changes to the `testenv`
-environment that we made to `testenv:check` above; remove the PyTest version and add
-`require_locked_deps = true`. Then imagine that we want to add the
-[Requests](https://requests.readthedocs.io/en/master/) library to the test environment: we
-can add `requests` as a dependency of the test environment, but this will cause an error:
+[`install_dev_deps`](#install_dev_deps) option to the environment configuration:

 ```ini
 [testenv]
-description = Run the tests
-require_locked_deps = true
-deps =
-    pytest
-    requests
-commands = ...
+description = Some very cool tests
+install_dev_deps = true
 ```

-Running Tox with this config gives us this error:
+See the [Reference](#reference) section for more details on available
+configuration options and the [Advanced Usage](#advanced-usage) section for some
+unusual use cases.

-```
-tox_poetry_installer.LockedDepNotFoundError: No version of locked dependency 'requests' found in the project lockfile
-```
-
-This is because `requests` is not in our lockfile yet. Tox will refuse to install a dependency
-that isn't in the lockfile to an an environment that specifies `require_locked_deps = true`. We
-can fix this by running `poetry add requests --dev` to add it to the lockfile.
-
-Now let's combine dependencies from the lockfile with dependencies that are
-specified in-line in the Tox environment configuration.
-[This isn't generally recommended](#why-would-i-use-this), but it is a valid use case and
-fully supported by this plugin. Let's modify the `testenv` configuration to install PyTest
-from the lockfile but then install an older version of the Requests library.
-
-The first thing to do is remove the `require_locked_deps = true` setting so that we can install
-Requests as an unlocked dependency. Then we can add our version specifier to the `requests`
-entry in the dependency list:
-
-```ini
-[testenv]
-description = Run the tests
-deps =
-    pytest
-    requests >=2.2.0,<2.10.0
-commands = ...
-```
-
-However we still want `pytest` to be installed from the lockfile, so the final step is to tell Tox
-to install it from the lockfile by adding the suffix `@poetry` to the `pytest` entry in the
-dependency list:
-
-```ini
-[testenv]
-description = Run the tests
-deps =
-    pytest@poetry
-    requests >=2.2.0,<2.10.0
-commands = ...
-```
-
-Now when the `testenv` environment is created it will install PyTest (and all of its dependencies)
-from the lockfile while it will install Requests (and all of its dependencies) using the default
-Tox installation backend.
-
-
-## Known Drawbacks and Problems
-
-* The following `tox.ini` configuration options have no effect on the dependencies installed from
-  the Poetry lockfile (note that they will still affect unlocked dependencies):
-  * [`install_command`](https://tox.readthedocs.io/en/latest/config.html#conf-install_command)
-  * [`pip_pre`](https://tox.readthedocs.io/en/latest/config.html#conf-pip_pre)
-  * [`downloadcache`](https://tox.readthedocs.io/en/latest/config.html#conf-downloadcache) (deprecated)
-  * [`download`](https://tox.readthedocs.io/en/latest/config.html#conf-download)
-  * [`indexserver`](https://tox.readthedocs.io/en/latest/config.html#conf-indexserver)
-  * [`usedevelop`](https://tox.readthedocs.io/en/latest/config.html#conf-indexserver)
-
-* Tox environments automatically inherit their settings from the main `testenv` environment. This
-  means that if the `require_locked_deps = true` is specified for the `testenv` environment then
-  all environments will also require locked dependencies. This can be overwritten by explicitly
-  specifying `require_locked_deps = false` on child environments where unlocked dependencies are
-  needed.
-
-* There are a handful of packages that cannot be installed from the lockfile, whether as specific
-  dependencies or as transient dependencies (dependencies of dependencies). This is due to
-  [an ongoing discussion in the Poetry project](https://github.com/python-poetry/poetry/issues/1584);
-  the list of dependencies that cannot be installed from the lockfile can be found
-  [here](https://github.com/python-poetry/poetry/blob/cc8f59a31567f806be868aba880ae0642d49b74e/poetry/puzzle/provider.py#L55).
-  This plugin will skip these dependencies entirely, but log a warning when they are encountered.

-## Why would I use this?
-
-**Introduction**
-
-The lockfile is a file generated by a package manager for a project that records what
-dependencies are installed, the versions of those dependencies, and any additional metadata that
-the package manager needs to recreate the local project environment. This allows developers
-to have confidence that a bug they are encountering that may be caused by one of their
-dependencies will be reproducible on another device. In addition, installing a project
-environment from a lockfile gives confidence that automated systems running tests or performing
-builds are using the same environment as a developer.
-
-[Poetry](https://python-poetry.org/) is a project dependency manager for Python projects, and
-so it creates and manages a lockfile so that its users can benefit from all the features
-described above. [Tox](https://tox.readthedocs.io/en/latest/#what-is-tox) is an automation tool
-that allows Python developers to run tests suites, perform builds, and automate tasks within
-self-contained [Python virtual environments](https://docs.python.org/3/tutorial/venv.html).
-To make these environments useful Tox supports installing dependencies in each environment.
-However, since these environments are created on the fly and Tox does not maintain a lockfile,
-there can be subtle differences between the dependencies a developer is using and the
-dependencies Tox uses.
-
-This is where this plugin comes into play.
-
-By default Tox uses [Pip](https://docs.python.org/3/tutorial/venv.html) to install the
-PEP-508 compliant dependencies to a test environment. This plugin extends the default
-Tox dependency installation behavior to support installing dependencies using a Poetry-based
-installation method that makes use of the dependency metadata from Poetry's lockfile.
+### Why would I use this?

 **The Problem**

+By default Tox uses Pip to install the [PEP-508](https://www.python.org/dev/peps/pep-0508/)
+compliant dependencies to a test environment. This plugin extends the default Tox
+dependency installation behavior to support installing dependencies using a Poetry-based
+installation method that makes use of the dependency metadata from Poetry's lockfile.
+
 Environment dependencies for a Tox environment are usually specified in PEP-508 format, like
 the below example:

 ```ini
-# from tox.ini
-...
-
 [testenv]
 description = Some very cool tests
 deps =
    foo == 1.2.3
    bar >=1.3,<2.0
    baz

 ```

+
+
+## Reference
+
+### Configuration Options
+
+All options listed below are Tox environment options and can be applied to one or more
+environment sections of the `tox.ini` file. They cannot be applied to the global Tox
+configuration section.
+
+**NOTE:** Environment settings applied to the main `testenv` environment will be
+inherited by child environments (i.e. `testenv:foo`) unless they are explicitly
+overridden by the child environment's configuration.
+
+#### `locked_deps`
+
+* **Type:** multi-line list
+* **Default:** `[]`
+
+Names of packages in the Poetry lockfile to install to the Tox environment. All
+dependencies specified here will be installed to the Tox environment using the details
+given by the Poetry lockfile.
+
+#### `require_locked_deps`
+
+
+* **Type:** boolean
+* **Default:** `false`
+
+Whether the environment should allow unlocked dependencies (dependencies not in the
+Poetry lockfile) to be installed alongside locked dependencies. If `true` then an error
+will be raised if the environment specifies unlocked dependencies to install and the
+plugin will block any other plugins from using the
+[`tox_testenv_install_deps`](https://tox.readthedocs.io/en/latest/plugins.html#tox.hookspecs.tox_testenv_install_deps)
+hook.
+
+#### `install_dev_deps`
+
+* **Type:** boolean
+* **Default:** `false`
+
+Whether all Poetry dev-dependencies should be installed to the environment. If `true`
+then all dependencies specified in the
+[`dev-dependencies`](https://python-poetry.org/docs/pyproject/#dependencies-and-dev-dependencies)
+section of `pyproject.toml` will be installed automatically.
+
+### Command-line Arguments
+
+All arguments listed below can be passed to the `tox` command to modify runtime behavior
+of the plugin.
+
+#### `--require-poetry`
+
+Indicates that Poetry is expected to be available to Tox and, if it is not, then the Tox
+run should fail. If provided and the `poetry` package is not installed to the same
+environment as the `tox` package then Tox will fail.
+
+**NOTE:** See [Advanced Usage](#installing-alongside-an-existing-poetry-installation)
+for more information.
+
+### Errors
+
+If the plugin encounters an error while processing a Tox environment then it will mark
+the environment as failed and set the environment status to one of the values below:
+
+**NOTE:** In addition to the reasons noted below, the plugin can encounter errors if the
+Poetry lockfile is not up-to-date with `pyproject.toml`. To resynchronize the
+lockfile with the `pyproject.toml` run one of
+[`poetry update`](https://python-poetry.org/docs/cli/#update) or
+[`poetry lock`](https://python-poetry.org/docs/cli/#lock)
+
+#### Poetry Not Installed Error
+
+* **Status value:** `PoetryNotInstalledError`
+* **Cause:** Indicates that the `poetry` module could not be imported from the same
+  environment as the running `tox` module and the runtime flags specified
+  [`--require-poetry`](#--require-poetry).
+* **Resolution options:**
+  * Install Poetry: ensure that `poetry` is installed to the same environment as `tox`.
+  * Skip running the plugin: remove the `--require-poetry` flag from the runtime options.
+
+**NOTE:** See [Advanced Usage](#installing-alongside-an-existing-poetry-installation)
+for more information.
+
+#### Locked Dependency Version Conflict Error
+
+* **Status value:** `LockedDepVersionConflictError`
+* **Cause:** Indicates that a dependency specified in the [`locked_deps`](#locked_deps)
+  configuration option in `tox.ini` includes a
+  [PEP-508 version specifier](https://www.python.org/dev/peps/pep-0508/#grammar)
+  (i.e. `pytest >=6.0, <6.1`).
+* **Resolution options:**
+  * Use the dependency version from the lockfile: remove any/all version specifiers
+    from the item in the `locked_deps` list in `tox.ini`.
+  * Do not install the dependency: remove the item from the `locked_deps` list in
+    `tox.ini`.
+
+#### Locked Dependency Not Found Error
+
+* **Status value:** `LockedDepNotFoundError`
+* **Cause:** Indicates that a dependency specified in the [`locked_deps`](#locked_deps)
+  configuration option in `tox.ini` could not be found in the Poetry lockfile.
+* **Resolution options:**
+  * Add the dependency to the lockfile: run
+    [`poetry add <dependency>`](https://python-poetry.org/docs/cli/#add).
+  * Do not install the dependency: remove the item from the `locked_deps` list in
+    `tox.ini`.
+
+#### Extra Not Found Error
+
+* **Status value:** `ExtraNotFoundError`
+* **Cause:** Indicates that the [`extras`](https://tox.readthedocs.io/en/latest/config.html#conf-extras)
+  configuration option specified a setuptools extra that is not configured by Poetry in
+  `pyproject.toml`
+* **Resolution options:**
+  * Configure the extra: add a section for the named extra to the
+    [`extras`](https://python-poetry.org/docs/pyproject/#extras) section of
+    `pyproject.toml` and optionally assign dependencies to the named extra using the
+    [`--optional`](https://python-poetry.org/docs/cli/#options_3) dependency setting.
+  * Remove the extra: remove the item from the `extras` list in `tox.ini`.
+
+#### Locked Dependencies Required Error
+
+* **Status value:** `LockedDepsRequiredError`
+* **Cause:** Indicates that an environment with the [`require_locked_deps`](#require_locked_deps)
+  configuration option also specified unlocked dependencies using
+  [`deps`](https://tox.readthedocs.io/en/latest/config.html#conf-deps) option in
+  `tox.ini`.
+* **Resolution options:**
+  * Remove all unlocked dependencies: remove the `deps` configuration option in
+    `tox.ini`.
+  * Allow unlocked dependencies: remove the `require_locked_deps` configuration option
+    in `tox.ini` or explicitly set `require_locked_deps = false`.
+
+### Advanced Usage
+
+#### Unsupported Tox configuration options
+
+The `tox.ini` configuration options listed below have no effect on the dependencies
+installed by this plugin the Poetry lockfile. Note that these settings will still be
+applied by the default Tox installation backend when installing unlocked dependencies
+using the built-in `deps` option.
+
+  * [`install_command`](https://tox.readthedocs.io/en/latest/config.html#conf-install_command)
+  * [`pip_pre`](https://tox.readthedocs.io/en/latest/config.html#conf-pip_pre)
+  * [`download`](https://tox.readthedocs.io/en/latest/config.html#conf-download)
+  * [`indexserver`](https://tox.readthedocs.io/en/latest/config.html#conf-indexserver)
+  * [`usedevelop`](https://tox.readthedocs.io/en/latest/config.html#conf-indexserver)
+
+All of these options are obsoleted by using the Poetry backend. If a given package
+installs successfully using Poetry (using either `poetry add <package>` or
+`poetry install`) then the required configuration options are already properly set in
+the Poetry configuration and the plugin will automatically use the same settings when
+installing the package.
+
+#### Reinstalling locked dependencies to a Tox environment
+
+Updating the `poetry.lock` file will not automatically cause Tox to install the updated
+lockfile specifications to the Tox environments that specify them.
+
+The Tox environment(s) with updated locked dependencies must be deleted and recreated
+using the [`--recreate`](https://tox.readthedocs.io/en/latest/config.html#cmdoption-tox-r)
+runtime flag. Alternatively Tox can be configured to always recreate an environment by
+setting the [`recreate`](https://tox.readthedocs.io/en/latest/config.html#conf-recreate)
+option in `tox.ini`.
+
+#### Installing Poetry's unsafe dependencies
+
+There are several packages that cannot be installed from the lockfile because they are
+excluded by Poetry itself. As a result these packages cannot be installed by this plugin
+either as environment dependencies (passed directly to [`locked_deps`](#locked_deps)) or
+as transient dependencies (a dependency of a locked dependency).
+
+As of [Poetry-1.1.4](https://github.com/python-poetry/poetry/releases/tag/1.1.4) there
+are four packages classified as "unsafe" by Poetry and excluded from the lockfile:
+
+* `setuptools`
+* `distribute`
+* `pip`
+* `wheel`
+
+When one of these packages is encountered by the plugin a warning will be logged and
+_**the package will not be installed to the environment**_. If the unsafe package
+is required for the environment then it will need to be specified as an unlocked
+dependency using the [`deps`](https://tox.readthedocs.io/en/latest/config.html#conf-deps)
+configuration option in `tox.ini`, ideally with an exact pinned version.
+
+* The set of packages excluded from the Poetry lockfile can be found in
+  [`poetry.puzzle.provider.Provider.UNSAFE_DEPENDENCIES`](https://github.com/python-poetry/poetry/blob/master/poetry/puzzle/provider.py)
+* There is an ongoing discussion of Poetry's handling of these packages at
+  [python-poetry/poetry#1584](https://github.com/python-poetry/poetry/issues/1584)
+
+#### Installing alongside an existing Poetry installation
+
+The plugin specifies the `poetry` package as an optional dependency to support an
+externally managed Poetry installation such as in a container or CI environment. This
+gives greater flexibility when using Poetry arguments like `--no-root`, `--no-dev`, or
+`--remove-untracked` which can cause Poetry to uninstall itself if Poetry is specified
+as a dependency of one of the packages it is managing (like this plugin).
+
+To have the plugin use the externally-managed Poetry package simply do not install the
+`poetry` extra when installing this plugin:
+
+```bash
+# Installing Poetry as a dependency with the plugin
+poetry add tox-poetry-installer[poetry]
+
+# Relying on an externally managed Poetry installation
+poetry add tox-poetry-installer
+```
+
+Note that Poetry is an optional dependency to support this use case _only_: Poetry must
+be installed to the same environment as Tox for the plugin to function. To check that
+the local environment has all of the required modules in scope run the below command:
+
+```bash
+python -c '\
+  import tox;\
+  import tox_poetry_installer;\
+  from poetry.poetry import Poetry;\
+'
+```
+
+**NOTE:** To force Tox to fail if Poetry is not installed, run the `tox` command with
+the [`--require-poetry`](#--require-poetry) option.

-"""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.

+"""You've heard of vendoirization, now get ready for internal namespace shadowing
+
+Poetry is an optional dependency of this package explicitly to support the use case of having the
+plugin and the `poetry` package installed to the same python environment; this is most common in
+containers and/or CI. In this case there are two potential problems that can arise in this case:
+
+* The installation of the plugin overwrites the installed version of Poetry resulting in
+  compatibility issues.
+* Running `poetry install --no-dev`, when this plugin is in the dev-deps, results in poetry being
+  uninstalled from the environment.
+
+To support these edge cases, and more broadly to support not messing with a system package manager,
+the `poetry` package dependency is listed as optional dependency. This allows the plugin to be
+installed to the same environment as Poetry and import that same Poetry installation here.
+
+However, simply importing Poetry on the assumption that it is installed breaks another valid use
+case: having this plugin installed alongside Tox when not using a Poetry-based project. To account
+for this the imports in this module are isolated and the resultant import error that would result
+is converted to an internal error that can be caught by callers. Rather than importing this module
+at the module scope it is imported into function scope wherever Poetry components are needed. This
+moves import errors from load time to runtime which allows the plugin to be skipped if Poetry isn't
+installed and/or a more helpful error be raised within the Tox framework.

Ethan Paul	872f6b0892	Update poetry dependency to be installed as optional extra When running 'poetry remove tox-poetry-installer' in the same env as poetry is installed to, poetry will uninstall itself. This is, obviously, not ideal. This change makes poetry an optional dependency so that the plugin can be installed (and uninstalled) alongside poetry in the same env without breaking the poetry installation. The intention is that the plugin can be installed with the 'poetry' extra when being installed to an isolated environment where poetry is not otherwise available. This is a mitigation of Issue #2 as an alternative to vendorization of the enitre poetry project 😬	2020-12-04 17:57:38 -05:00
