Nitpick

Command-line tool and flake8 plugin to enforce the same settings across multiple language-independent projects.

Useful if you maintain multiple projects and are tired of copying/pasting the same INI/TOML/YAML/JSON keys and values over and over, in all of them.

The tool now has an "apply" feature that modifies configuration files directly (pretty much like black and isort do with Python files). See the CLI docs for more info.

Many more features are planned for the future, check the roadmap.

Style file

A "nitpick code style" is a TOML file with the settings that should be present in config files from other tools.

Example of a style:

["pyproject.toml".tool.black]
line-length = 120

["pyproject.toml".tool.poetry.dev-dependencies]
pylint = "*"

["setup.cfg".flake8]
ignore = "D107,D202,D203,D401"
max-line-length = 120
inline-quotes = "double"

["setup.cfg".isort]
line_length = 120
multi_line_output = 3
include_trailing_comma = true
force_grid_wrap = 0
combine_as_imports = true

This style will assert that:

• ... black, isort and flake8 have a line length of 120;
• ... flake8 and isort are configured as above in setup.cfg;
• ... Pylint is present as a Poetry dev dependency in pyproject.toml).

Quick setup

To try the package, simply install it (in a virtualenv or globally) and run flake8 on a project with at least one Python (.py) file:

# Install using pip:
$ pip install -U nitpick

# Or using Poetry:
$ poetry add --dev nitpick

$ flake8 .

Nitpick will download and use the opinionated default style file.

You can use it as a template to configure your own style.

Run as a pre-commit hook (recommended)

If you use pre-commit on your project (you should), add this to the .pre-commit-config.yaml in your repository:

repos:
  - repo: https://github.com/andreoliwa/nitpick
    rev: v0.26.0
    hooks:
      - id: nitpick

To install the pre-commit and commit-msg Git hooks:

pre-commit install --install-hooks
pre-commit install -t commit-msg

To start checking all your code against the default rules:

pre-commit run --all-files
