# 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
# necessary check for initial commit
if git rev-parse --verify HEAD >/dev/null 2>&1
then
against=HEAD
else
# Initial commit: diff against an empty tree object
against=4b825dc642cb6eb9a060e54bf8d69288fbee4904

# get a list of staged .php files, omitting file removals

# store lint result in a temp file
