Questions tagged [pre-commit]

Pre-commit is an action taken prior to committing your code into a version control system.

A pre-commit is an action that would be applied to source code before it is committed to the version control system. To utilize a pre-commit action you'll need to install a pre-commit hook into the repository. Pre-commit hooks are available in most commonly used version control systems such as SVN or git.

Some actions that could be achieved using pre-commit hooks:

  1. Fixing case issues in file names
  2. Validating file content, such as executing a linter or code convention checker.
  3. Preventing specific users from committing code

pre-commit is also the name of a framework for managing such hooks for git.
