  36 # This script is intended as a pre-commit hook that optionally runs all
  37 # changes through some formatting check.  Currently, it runs uncrustify and
  38 # checks copyright headers.
  39 #
  40 # It needs to be copied as .git/hooks/pre-commit and configured with
  41 #   git config hooks.uncrustifypath /path/to/uncrustify
  42 #   git config hooks.uncrustifymode check
  43 #   git config hooks.copyrightmode update
  44 #
  45 # To disable the hook temporarily for a commit, set NO_FORMAT_CHECK environment
  46 # variable.  For example,
  47 #   NO_FORMAT_CHECK=1 git commit -a
  48 # You can also run git commit --no-verify, but that also disables other hooks,
  49 # such as the Change-Id hook used by Gerrit.
  50 #
  51 # See docs/dev-manual/uncrustify.rst for more details.
