brunette

🟤 A best practice Python code formatter

This is the "black" formatter but with some improvements:

• --config option supports setup.cfg format.
  • Where a single-quotes option enables single quotes as the preferred.
• --single-quotes option to make single quotes the preferred.

Installation

pip install brunette

Usage

Use in the same way you would the 'black' formatter.

brunette **/*.py
brunette *.py --config=setup.cfg
brunette *.py --line-length=79 --single-quotes

Example setup.cfg:

[tool:brunette]
line-length = 79
verbose = true
single-quotes = false
# etc, etc...

This can also be combined with Flake8's configuration:

[flake8]
# This section configures `flake8`, the python linting utility.
# See also https://flake8.pycqa.org/en/latest/user/configuration.html
ignore = E201,E202,E203
# E201 - whitespace after ‘(‘
# E202 - whitespace before ‘)’
# E203 - whitespace before ‘:’

# Exclude the git directory and virtualenv directory (as `.env`)
exclude = .git,.env

[tool:brunette]
line-length = 79
# etc, etc...

Why does this need to exist?

• The current maintainer of Black, refuses to allow a single-quotes option. Due to his own personal preference (a preference which most of the Python community do not share).

• The current maintainer of Black, refuses to add setup.cfg support. Setup.cfg is the most widely used configuration file for Python projects. The maintainer of that library prefers "pyproject.toml" few people use at this time due to it's inflexibility and it requiring you to use Poetry, whatever that is.

• The current configuration file format as adopted by Black may conflict with the new build isolation context with pip. To avoid this, the use of a setup.cfg file is preferred but the policy is under review by the maintainers (https://github.com/pypa/pip/issues/8437#issuecomment-644196428).

How to configure in VSCode

• Get the full path to your brunette installation. In your terminal type:

• which brunette (Linux)
• where brunette (Windows)

In my case this looks like /home/work/.pyenv/shims/brunette. On Windows thats more like C:\Python39\Scripts\brunette.exe. Now copy whatever that value is.\

• Open the setttings UI.

• Search for black.

• Paste that path into Black Path.
• Set black as the Python Formatting Provider.
• Add arguments as --single-quotes you like to the Black Args

• That's it! Now whenever you format your Python code brunette will be used.
