Jupytext pre-commit hook

Hook for Jupytext with conda as a language. Currently the main Jupytext-repo doesn't have pre-commit hooks defined, so this repo is called mirror only for consistency.

• For pre-commit: see https://github.com/pre-commit/pre-commit
• For Jupytext: see https://github.com/mwouts/jupytext

Using Jupytext with pre-commit and conda:

Add this to your .pre-commit-config.yaml:

- repo: https://github.com/Quantco/pre-commit-mirrors-jupytext
  rev: ''  # The git sha / tag you want to point to
  hooks:
    - id: jupytext-conda
    - args:
      - --to=py:percent

args is optional and allows passing further parameters to jupytext. By default only --to=py:percent is passed which converts all Jupyter notebooks to Python scripts using the percent formatting.
