It's a Flake8 wrapper to make it cool.

• Sharable and remote configs.
• Legacy-friendly: ability to get report only about new errors.
• Use only specified plugins, not everything installed.
• Manage codes per plugin.
• Enable and disable plugins and codes by wildcard.
• Make output beautiful.
• pyproject.toml support.
• Show codes for installed plugins.
• Show all messages and codes for a plugin.
• Check that all required plugins are installed.
• Syntax highlighting in messages and code snippets.
• PyLint integration.

Installation

python3 -m pip install --user flakehell

Usage

First of all, let's create pyproject.toml config:

[tool.flakehell]
# optionally inherit from remote config (or local if you want)
base = "https://raw.githubusercontent.com/life4/flakehell/master/pyproject.toml"
# specify any flake8 options. For example, exclude "example.py":
exclude = ["example.py"]
# make output nice
format = "grouped"
# 80 chars aren't enough in 21 century
max_line_length = 90
# show line of source code in output
show_source = true

# list of plugins and rules for them
[tool.flakehell.plugins]
# include everything in pyflakes except F401
pyflakes = ["+*", "-F401"]
# enable only codes from S100 to S199
flake8-bandit = ["-*", "+S1??"]
# enable everything that starts from `flake8-`
"flake8-*" = ["+*"]
# explicitly disable plugin
flake8-docstrings = ["-*"]

Show plugins that aren't installed yet:

flakehell missed

Show installed plugins, used plugins, specified rules, codes prefixes:

flakehell plugins

Show codes and messages for a specific plugin:

flakehell codes pyflakes

Run flake8 against the code:

flakehell lint

This command accepts all the same arguments as Flake8.
