Rubric

>> Linter Config Initializer for Python <<

 

Preface

Rubric initializes the configuration files of a few Python linters and formatters. Also, it adds a README.md boilerplate and a simple Makefile with the commands to apply the tools. This helps you maintain an isomorphic workflow across multiple projects. It assumes that, in all of your Python projects, you'll use—

• Black as the primary code formatter.
• EditorConfig to enforce consistent style across different editors.
• Ruff to ensure style guide conformance and sort the imports.
• Mypy to check the type hints.
• Pip-tools to manage the dependencies.
• [Hatch][hatch] to generate build artifacts for reusable libraries.
• Pre-commit for managing and maintaining the pre-commit hooks.

Following is a list of config files that Rubric is going to add to your target directory:

root
├── .editorconfig           # Config file for Editorconfig
├── .gitignore              # Python specific .gitignore file
├── .pre-commit-config.yaml # Config to manage pre-commit hooks.
├── Makefile                # Makefile containing the commands to lint your code
├── pyproject.toml          # Toml file to with the configs for black, ruff, and mypy
├── README.md               # A readme boilerplate
├── requirements-dev.txt    # File to specify the dev requirements
└── requirements.txt        # File to specify the pinned app requirements

The files will contain minimal but sensible default configurations for the respective tools. You're free to change them as you like.

Installation

• Rubric requires Python 3.8 and up.

• Make a virtual environment in your project's root directory.

• Activate the environment and run:

  pip install rubric
  

Usage

• To inspect all the CLI options, run:

  rubric --help
  

  You should see the following output:

  $ rubric --help
                 >> Config Initializer for Python Projects <<
  
  Usage: rubric [OPTIONS]
  
  Options:
  -h, --help                      Display help message.
  -v, --version                   Display the version number.
  -s, --show                      Show the contents of the config files.
  -a, --append                    Append to existing config files.
  -o, --overwrite                 Overwrite existing config files.
  -c, --create                    Create the config files in the current
                                  directory.
  -f, --filename [.editorconfig|.gitignore|.pre-commit-config.yaml|README.md|
          Makefile|pyproject.toml|requirements-dev.in|requirements-dev.txt|
          requirements.in|requirements.txt]
                                  Target file names.
  -d, --dirname PATH              Target directory name.
  -l, --list                      List the config files that are about to be
                                  generated.
  
  

• Display a list of config files that are going to be created:

  rubric --list
  

  Config files that are about to be generated:
  
  => .editorconfig
  => .gitignore
  => .pre-commit-config.yaml
  => README.md
  => Makefile
  => pyproject.toml
  => requirements-dev.txt
  => requirements.txt
  

• Take a peek into the content of any config file(s):

  rubric --show -f requirements.txt -f .editorconfig
  

  This will print:

  ============================ requirements.txt ============================
  
  #
  # This file is autogenerated by pip-compile with python 3.11
  # To update, run:
  #
  #    pip-compile --output-file=requirements.txt requirements.in
  #
  
  ============================ .editorconfig ============================
  
  # https://editorconfig.org
  
  root = true

  indent_style = tab
  

• Initialize a project with the following command:

  rubric --create
  

  This will run the tool in a non-destructive way—that means it won't overwrite any of the configuration files that you might already have in the directory.

• If you only want to create a selected list of config files, then run:

  rubric --create -f requirements.txt -f requirements-dev.txt
  

• If you want to overwrite any of the existing config files that you might have in the directory, then run:

  rubric --overwrite -f filename1 -f filename2
  

• If you want to append the configs to an existing file, then run:

  rubric --append -f filename1 -f filename2
  

• You can also point Rubric to a directory.

  rubric --create --directory "some/custom/directory"
  

• If you want to check and update the configs across multiple repositories in a single sweep, use the following command:

  s="dir1 dir2 dir3"; echo $s | xargs -n 1 -P $(echo $s | wc -w) rubric -c -d
  

  This command will spawn 3 processes to create the config files in dir1, dir2, and dir3 in parallel.

• You can run the entire linter suite with this command:

  make lint
