Tox：针对 flake8 和 pylint 等工具的每个平台配置

Question

我在 linux 和 windows 环境中都为 ci 配置了 tox.ini，类似于：

[tox]
envlist =
    {py3,py27}-{test,lint}-{linux,windows}
    flake8
    check-package
skip_missing_interpreters = true
isolated_build = True
distdir = dist

[testenv]
platform =
    linux: linux
    windows: win

# Reuse py3 and py27 envs for pylint
envdir =
    py3: {toxworkdir}/py3
    py27: {toxworkdir}/py27
    !py3-!py27: {toxworkdir}/{envname}
deps =
    py27: setuptools < 45.0.0

# test extras must include pytest and pylint
extras = test
commands =
    test: python -m pytest -c {toxinidir}/pytest.ini --junitxml=test-reports/pytest.{envname}.xml {posargs}
    lint: python -m pylint --rcfile=tox.ini src/displaylink {posargs}

[testenv:flake8]
basepython = python3
skip_install = true
deps = flake8
commands = flake8 src tests

[tool:pylint]
disable = missing-docstring,
          R,
          C,
          line-too-long
output-format = parseable
reports = no
extension-pkg-whitelist = win32api, win32gui

[flake8]
ignore = E501, E722, W503
per-file-ignores =
    # imported but unused
    __init__.py: F401
max-complexity = 10

问题是如何为工具（flake 和 pylint）添加每个平台的配置？我需要从 flake8 中排除 files/dirs 并且 pylint 根据 os 运行，即我有 windows 子目录，其中的文件不会在 linux 上通过 linting，副相反

编辑：

我在 linux:

上遇到的 pylint 错误示例

py3-lint-linux run-test: commands[0] | python -m pylint --rcfile=tox.ini src/displaylink

************* Module displaylink.qa.windows.registry
registry.py:4: [E0401(import-error), ] Unable to import 'win32con'
registry.py:74: [E0602(undefined-variable), reg_value_exists] Undefined variable 'WindowsError'
registry.py:82: [E0602(undefined-variable), reg_key_exists] Undefined variable 'WindowsError'

也许我遗漏了您要求的某些部分，但是运行 flake8 平台特定似乎很简单：

[testenv]
platform =
    linux: linux
    windows: win

[testenv:flake8]
deps = flake8
commands =
    linux: flake8 <linux specific directories>
    windows: flake8 <windows specific directories>

也比较 official documentation。
