 response to any behavior that they deem inappropriate, threatening, offensive,
 or harmful.
 Community leaders have the right and responsibility to remove, edit, or reject
 comments, commits, code, wiki edits, issues, and other contributions that are
 not aligned to this Code of Conduct, and will communicate reasons for moderation
 decisions when appropriate.
 ## Scope
 This Code of Conduct applies within all community spaces, and also applies when
 an individual is officially representing the community in public spaces.
 Examples of representing our community include using an official e-mail address,
 posting via an official social media account, or acting as an appointed
 representative at an online or offline event.
 ## Enforcement
 Instances of abusive, harassing, or otherwise unacceptable behavior may be
 reported to the community leaders responsible for enforcement at
 [INSERT CONTACT METHOD].
 All complaints will be reviewed and investigated promptly and fairly.
 All community leaders are obligated to respect the privacy and security of the
 reporter of any incident.
 ## Enforcement Guidelines
 Community leaders will follow these Community Impact Guidelines in determining
 the consequences for any action they deem in violation of this Code of Conduct:
 ### 1. Correction
 **Community Impact**: Use of inappropriate language or other behavior deemed
 unprofessional or unwelcome in the community.
 **Consequence**: A private, written warning from community leaders, providing
 clarity around the nature of the violation and an explanation of why the
 behavior was inappropriate. A public apology may be requested.

 * [Tox plugins](https://tox.readthedocs.io/en/latest/plugins.html)
 ## Installation
 Add the plugin as a development dependency a project using Poetry:
 ```
 ~ $: poetry add tox-poetry-installer --dev
 ```
 Confirm that the plugin is installed, and Tox recognizes it, 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-0.2.0 at .venv/lib64/python3.8/site-packages/tox_poetry_installer.py
 ```
 If using in a CI/automation environment using Pip, ensure that the plugin is installed to the
 same environment as Tox:
 ```
 # Calling the virtualenv's 'pip' binary directly will cause pip to install to that virtualenv
 ~ $: /path/to/my/automation/virtualenv/bin/pip install tox
 ~ $: /path/to/my/automation/virtualenv/bin/pip install tox-poetry-installer
 ```
 ## 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:
 ```ini
 [testenv]
 description = Run the tests
 require_locked_deps = true
 deps =
    pytest
    pytest-cov
    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 method, add the suffix `@poetry` to the dependencies.
 In the example below the `pytest`, `pytest-cov`, and `black` dependencies will be installed using
 the lockfile while `pylint` and `mypy` will be installed using the versions specified here:
 ```ini
 [testenv]
 description = Run the tests
 require_locked_deps = true
 deps =
    pytest@poetry
    pytest-cov@poetry
    black@poetry
    pylint >=2.5.0
    mypy == 0.770
 commands = ...
 ```
 **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
 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 checks:
 ```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 to 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 got 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 a new (made up) tool the test
 environment called `crash_override` to the environment: we can add `crash-override` as a dependency
 of the test environment, but this will cause an error:
 ```ini
 [testenv]
 description = Run the tests
 require_locked_deps = true
 deps =
    pytest
    crash-override
 commands = ...
 ```
 Running Tox with this config gives us this error:
 ```
 tox_poetry_installer.LockedDepNotFoundError: No version of locked dependency 'crash-override' found in the project lockfile
 ```
 This is because `crash-override` is not in our lockfile. Tox will refuse to install a dependency
 that isn't in the lockfile to an an environment that specifies `require_locked_deps = true`. We
 could fix this (if `crash-override` was a real package) by running
 `poetry add crash-override --dev` to add it to the lockfile.
 Now let's combine dependencies from the lockfile ("locked dependencies") with dependencies that are
 specified inline in the environment configuration ("unlocked dependencies").
 [This isn't generally recommended of course](#why-would-i-use-this), but it's 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](https://requests.readthedocs.io/en/master/) 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 of requests to 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 it:
 ```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 using Pip.
 ## 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)
 * The [`extras`](https://tox.readthedocs.io/en/latest/config.html#conf-extras) setting in `tox.ini`
  does not work. Optional dependencies of the project package will not be installed to Tox
  environments. (See the [road map](#roadmap))
 * The plugin currently depends on `poetry<1.1.0`. This can be a different version than Poetry being
  used for actual project development. (See the [road map](#roadmap))
 * 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 point of using a lockfile is to create reproducable builds](https://docs.gradle.org/current/userguide/dependency_locking.html). One of the main points of Tox is to [allow a Python
 package to be built and tested in multiple environments](https://tox.readthedocs.io/en/latest/#what-is-tox). However, in the Tox configuration file the dependencies are specified with
 standard dynamic ranges and passed directly to Pip. This means that the reproducability
 a lockfile brings to a project is circumvented when running the tests.
-The lockfile is a file generated by a package manager for a project that lists what

 as such 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 per-environment dependencies.
 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.
+Traditionally Tox environments specify dependencies and their corresponding versions inline in
-
+[PEP-440](https://www.python.org/dev/peps/pep-0440/) format like below:
 By default Tox uses [Pip](https://docs.python.org/3/tutorial/venv.html) to install the
 PEP-508 compliant dependencies to a test environment. A more robust way to do this is to
 install dependencies directly from the lockfile so that the version installed to the Tox
 environment always matches the version Poetry specifies. This plugin overwrites the default
 Tox dependency installation behavior and replaces it with a Poetry-based installation using
 the dependency metadata from the lockfile.
 **The Problem**
 Environment dependencies for a Tox environment are usually done in PEP-508 format like the
 below example
 ```ini
 # tox.ini
 ...
 [testenv]
-description = Some very cool tests
+description = Run the tests
 deps =
-    foo == 1.2.3
+  foo == 1.2.3
-    bar >=1.3,<2.0
+  bar >=1.3,<2.0
-    baz
+  baz
 ...
 ```
-Perhaps these dependencies are also useful during development, so they can be added to the
+This runs into the problem outlined above: many different versions of the `bar` dependency
-Poetry environment using this command:
+could be installed depending on what the latest version is that matches the defined range. The
 `baz` dependency is entirely unpinned making it a true wildcard, and even the seemingly static
 `foo` dependency could result in subtly different files being downloaded depending on what's
 available in the upstream mirrors.
- ```
+However these same versions, specified in the [pyproject.toml](https://snarky.ca/what-the-heck-is-pyproject-toml/) file, result in reproducible
- poetry add foo==1.2.3 bar>=1.3,<2.0 baz --dev
+installations when using `poetry install` because they each have a specific version and file
- ```
+hash specified in the lockfile. The versions specified in the lockfile are updated only when
 `poetry update` is run.
- However there are three potential problems that could arise from each of these environment
+This plugin allows environment dependencies to be specified in the [tox.ini](https://tox.readthedocs.io/en/latest/config.html) configuration file

   it. A developer can run `poetry remove foo && poetry add foo^1.2` to get the new version,
   but the Tox environment is left unchanged. The developer environment specified by the
   lockfile is now patched against the vulnerability, but the Tox environment is not.
 * **The `bar` dependency specifies a dynamic range:** a dynamic range allows a range of
  versions to be installed, but the lockfile will have an exact version specified so that
  the Poetry environment is reproducible; this allows versions to be updated with
  `poetry update` rather than with the `remove` and `add` used above. If the maintainers of
  `bar` release version `1.6.0` then the Tox environment will install it because it is valid
  for the specified version range, meanwhile the Poetry environment will continue to install
  the version from the lockfile until `poetry update bar` explicitly updates it. The
  development environment is now has a different version of `bar` than the Tox environment.
 * **The `baz` dependency is unpinned:** unpinned dependencies are
  [generally a bad idea](https://python-poetry.org/docs/faq/#why-are-unbound-version-constraints-a-bad-idea),
  but here it can cause real problems. Poetry will interpret an unbound dependency using
  [the carrot requirement](https://python-poetry.org/docs/dependency-specification/#caret-requirements)
  but Pip (via Tox) will interpret it as a wildcard. If the latest version of `baz` is `1.0.0`
  then `poetry add baz` will result in a constraint of `baz>=1.0.0,<2.0.0` while the Tox
  environment will have a constraint of `baz==*`. The Tox environment can now install an
  incompatible version of `baz` that cannot be easily caught using `poetry update`.
 All of these problems can apply not only to the dependencies specified for a Tox environment,
 but also to the dependencies of those dependencies, and so on.
 **The Solution**
 This plugin requires that all dependencies specified for all Tox environments be unbound
 with no version constraint specified at all. This seems counter-intuitive given the problems
 outlined above, but what it allows the plugin to do is offload all version management to
 Poetry.
 On initial inspection, the environment below appears less stable than the one presented above
 because it does not specify any versions for its dependencies:
 ```ini
 # tox.ini
 ...
 [testenv]
 description = Some very cool tests
 deps =
    foo
    bar
    baz
 ...
 ```
 However with the `tox-poetry-installer` plugin installed this instructs Tox to install these
 dependencies using the Poetry lockfile so that the version installed to the Tox environment
 exactly matches the version Poetry is managing. When `poetry update` updates the lockfile
 with new dependency versions, Tox will automatically install these new versions without needing
 any changes to the configuration.
 All dependencies are specified in one place (the lockfile) and dependency version management is
 handled by a tool dedicated to that task (Poetry).

 usage in production systems.
 * Beta classification will be assigned when the initial feature set is finalized
 * Stable classification will be assigned when the test suite covers an acceptable number of
  use cases
 ### Path to Beta
 - [X] Verify that primary package dependencies (from the `.package` env) are installed
      correctly using the Poetry backend.
 - [ ] Support the [`extras`](https://tox.readthedocs.io/en/latest/config.html#conf-extras)
      Tox configuration option
 - [X] Add per-environment Tox configuration option to fall back to default installation
      backend.
 - [ ] Add detection of a changed lockfile to automatically trigger a rebuild of Tox
      environments when necessary.
 - [ ] Add warnings when an unsupported Tox configuration option is detected while using the
      Poetry backend.
 - [X] Add trivial tests to ensure the project metadata is consistent between the pyproject.toml
      and the module constants.
 - [ ] Update to use [poetry-core](https://github.com/python-poetry/poetry-core)
      Tox configuration option) and improve robustness of the Tox and Poetry module imports
      to avoid potentially breaking API changes in upstream packages.
 - [ ] Find and implement a way to mitigate the [Poetry UNSAFE_DEPENDENCIES bug](https://github.com/python-poetry/poetry/issues/1584).
 ### Path to Stable
