pre-commit-stats

Some stats about the usage of pre-commit hooks on GitHub.

These are generated using GitHub's code search.

The results of my crawling are checked in under all_repos.json (listing all public repos revealed by the search that use pre-commit) and hook_users.json (showing which repos use which particular hook).

At the time of writing (January 2017), the most popular hooks are:

Running these scripts

• Create a python3 virtualenv and pip install requirements.txt.
• Go create a throwaway GitHub user.
• Run get_stats.py. The results are cached as JSON files in the repo, so if you actually want to collect the data again, delete those first.
