# A hook to disallow php syntax errors to be committed
|
|
# by running php -l (lint) on them. It requires php-cli
|
|
# to be installed.
|
|
#
|
|
# This is a pre-commit hook.
|
|
#
|
|
# To install this you can either copy or symlink it to
|
|
# $GIT_DIR/hooks, example:
|
|
#
|
|
# ln -s ../../git-tools/hooks/pre-commit \\
|
|
# .git/hooks/pre-commit
|
|
|
|
# NOTE: this is run through /usr/bin/env
|
