Pre-commit

This repository contains an example pre-commit configuration.

pre-commit is a tool that uses Git hooks to identify and resolve simple issues before submission for code review. Git hooks run on every commit to automatically point out and solve issues such as missing semicolons, trailing whitespaces, code formatting and spell checks.

Setting up pre-commit for R project

• Install the pre-commit framework. Use the official installation guide.

• Install R package precommit

  R -e 'install.packages("precommit")'

• Run the use_precommit() function to generate an example pre-commit configuration called .pre-commit-config.yaml:

  [ ! -f ".pre-commit-config.yaml" ] && R -e 'precommit::use_precommit()'

• Install the git hooks script:

  pre-commit install

• From this moment on, all scripts from .pre-commit-config.yaml will run before every git commit command. If you want to run them manually without committing you can use command pre-commit run --all-files. For more information, please refer to the official pre-commit documentation.

NOTE: Frequently run pre-commit autoupdate to update all hooks in the .pre-commit-config.yaml configuration file.
