upadup -- Utility for Python additional_dependencies Updates in Pre-Commit

pre-commit is great, and pre-commit autoupdate is also great. However, what's not great is that pre-commit autoupdate cannot update your additional_dependencies lists.

upadup is a supplemental tool which knows how to handle specific common cases.

upadup will only update additional_dependencies items which are pinned to specific versions, and only for known python hooks and their dependencies.

Simply cd myrepo; upadup!

upadup can also be configured with information about hooks which are unknown to it. More on this below.

If you have hooks outside of the defaults which you want upadup to examine, drop a .upadup.yaml file into your repo to configure which hooks to update.

upadup takes no arguments and automatically reads .upadup.yaml from the current directory if available. Otherwise, it uses its default configuration.

upadup needs to know what hook repos you want it to examine, and within those which dependencies you want it to keep updated. The config format intentionally mirrors your pre-commit config. Specify a list of repos, and in each repo, specify a list of hooks to update. Hooks are a combination of id (the hook ID) and additional_dependencies.

For example:

# .upadup.yaml
repos:
  - repo: https://github.com/pycqa/flake8
    hooks:
      - id: flake8
        additional_dependencies:
          - flake8_bugbear

This configuration would match the following pre-commit config:

# .pre-commit-config.yaml
repos:
  - repo: https://github.com/PyCQA/flake8
    rev: 5.0.4
    hooks:
      - id: flake8
        additional_dependencies:
          - 'flake8-bugbear==22.7.1'

Note that matching is case insensitive for repo names and additional_dependencies, and that we normalize - and _ to match, as pypi.org does. But the overall structure of the config is intended to be a mirror image.

The following config is the upadup default. Note that missing dependencies are ignored.

repos:
  - repo: https://github.com/pycqa/flake8
    hooks:
      - id: flake8
        additional_dependencies:
          - flake8-bandit
          - flake8-bugbear
          - flake8-builtins
          - flake8-comprehensions
          - flake8-docstrings
          - flake8-implicit-str-concat
          - flake8-logging-format
          - flake8-pyi
          - flake8-typing-as-t
          - flake8-typing-imports

  - repo: https://github.com/adamchainz/blacken-docs
    hooks:
      - id: blacken-docs
        additional_dependencies:
          - black

  # Old hook URLs
  # -------------

  - repo: https://github.com/asottile/blacken-docs
    hooks:
      - id: blacken-docs
        additional_dependencies:
          - black

Unless otherwise specified, the default config will be merged with your .upadup.yaml configuration, effectively a union.

You can disable this behavior by setting extends_default: false, as in

extends_default: false
repos:
  - repo: https://github.com/pycqa/flake8
    hooks:
      - id: flake8
        additional_dependencies:
          - flake8-bugbear

Update python additional depenedencies uh... pre-commit!

Unbelievably playful, awesome, deterministic update program
