| # An example hook script to verify what is about to be committed. | |
| # Called by "git commit" with no arguments. The hook should | |
| # exit with non-zero status after issuing an appropriate message if | |
| # it wants to stop the commit. | |
| # | |
| # To enable this hook, rename this file to "pre-commit". | |
| # Added a prompt to allow commiting anyways even if there are style isseus. | |
| # Put filters in an array. I thought it was easier to add or remove them when each one is on its own line. | |
