# This script ensures Crystal code is correctly formatted before committing it.

# It won't apply any format changes automatically.

# Only staged files (the ones to be committed) are being processed, but each file is checked
|
|
# entirely as it is stored on disc, even parts that are not staged.

# To use this script, it needs to be installed in the local git repository. For example by running
|
|
# `ln -s scripts/git/pre-commit .git/hooks` in the root folder.
|

#
|
|
# 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.
