# Hook called before a commit is created. It will try to format each file which
|
|
# has been added/copy/modified/renamed up to a maximum of 5 times and if a
|
|
# stable code formatting can be achieved, the commit operation will be allowed
|
|
# to proceed. If no stable code formatting is achieved in 5 passes, the commit
|
|
# operation will be aborted.

# Note on amended commits. Amending a commit can add/modify/remove files to/from an
|
|
# original commit. The pre-commit hook was already run against the original commit files
|
|
# when that commit was created. The pre-commit hook ran on an amended commit will only
|
|
# check those files which have actually been added/modified compared to the original commit.
|

# Files that were not touched by the amending operation, will not be tested again.
