Pre-commit Exclusions Updater

A simple script and pre-commit hook to automatically update the exclude regex patterns in your .pre-commit-config.yaml. This tool helps maintain clean and consistent exclusions across multiple repositories by merging default exclusions with custom rules.

---

Features

• Reads default exclusions and appends custom exclusions from a separate file.
• Updates the exclude: block in .pre-commit-config.yaml safely.
• Can be used as a standalone script or integrated as a pre-commit hook.
• Designed to be reused across hundreds of repositories.

---

Usage

Before using the script or hook, ensure your .pre-commit-config.yaml file contains the exclude: block delimited by these two comment lines exactly as shown:

# Start exclude
exclude: |
# End exclude

This allows the script to correctly locate and replace the exclusion patterns.

Standalone

Place your default exclusions in .pre-commit-default-exclusions and your custom exclusions in .pre-commit-exclusions.

Run the update script:

./update_exclusions.sh

As a pre-commit hook

Add the following to your .pre-commit-config.yaml:

- repo: https://github.com/Romathi/pre-commit-exclusions
  rev: v0.2.2
  hooks:
    - id: update-exclusions
