Useful git pre-commit hooks for R

CRAN status Lifecycle: stable R build status

Pre-commit hooks are tests that run each time you attempt to commit. If the tests pass, the commit will be made, otherwise not. A very basic test is to check if the code is parsable, making sure you have not forgotten a comma, brace or quote. You can run hooks locally and/or in the cloud:

  • As a check before local commits: This requires installing pre-commit.

  • As a CI check with If you want to enforce passing hooks on pull requests (and auto-fix trivial problems like styling) even if the committer does not have a local installation.

Goals of the package

The goal of this package is to twofold:

  • Provide a set of hooks that are useful when your git repo contains R code.

  • Provide usethis-like functionality for common tasks such as installation and set-up and config file modification.

The following online docs are available:

These only cover the functionality added on top of the pre-commit framework by this package. Everything else is covered in the extensive online documentation of the pre-commit framework itself, including how to create hooks for actions like git push or git checkout, create local hooks etc.
