Poetry integration

[johnthagen]

Poetry recently went 1.0, and looks pretty good. It's inspired by really solid package managers like Cargo.

There are some tox related issues that looked a bit concerning.

Should continue to monitor it, and if it continues to gain market share and maturity, consider switching from recommending pip-tools to poetry.

PyCharm support for poetry feature request: https://youtrack.jetbrains.com/issue/PY-30702

Edit: This should be in PyCharm 2021.3.

The latest tox configuration I have been trying with Poetry using tox-poetry-installer:

[tox]
envlist =
    fmt-check
    lint
    docs
    py{38,39}
skipsdist = true
skip_missing_interpreters = true
isolated_build = true
requires =
    tox-poetry-installer[poetry] == 0.8.1

[testenv]
require_locked_deps = true
install_project_deps = true
install_dev_deps = true
commands =
    {envpython} -m pytest --cov=fact --cov-report=html --cov-report=term {posargs}

[testenv:type-check]
install_project_deps = false
# Require all dev_deps to install types-* packages.
install_dev_deps = true
commands =
    mypy src tests

[testenv:lint]
install_project_deps = false
install_dev_deps = false
locked_deps =
    flake8
    pep8-naming
commands =
    flake8

[testenv:fmt]
install_project_deps = false
install_dev_deps = false
locked_deps =
    isort
    black
commands =
    isort .
    black .

[testenv:fmt-check]
install_project_deps = false
install_dev_deps = false
locked_deps =
    isort
    black
commands =
    isort --check-only .
    black --check .

I'd like to chime in and say that poetry integration would be marvellous

The export command can be used to work around the Poetry bootstrapping issue where a project is moved into a network where Poetry is challenging to install (but pip is bundled with Python).

Poetry 1.2 dependency groups look very promising. After 1.2 is released and the dust settles, investigate Poetry and PyCharm support for 1.2.
