pre-commit

#!/bin/bash

# This script is a wrapper around the run-tests script.
# It is highly recommended to link it as the git pre-commit hook via:

# ln -s ../../pre-commit .git/hooks/pre-commit

# The difference to the run-tests script is that this script stashes
# unstaged changes before testing (see below). Thus only the changeset to be
# commited will be tested. No worries, "git commit -a" will still work ;)
# Stephan Kuschel, 2014

# Stash unstaged changes if and only if(!) necessary (=possible):
# if you dont check that you might uninentionally apply an older stash,
# because this if statement just makes sure, that there are changed to
# be stashed on executing "git staph -q --keep-index". Otherwise it coud
# happen, that git stash is executed, but no stash is created, because
# there were no changes, that could be stashed.

    #echo "pre-commit hook without stashing"
    ./run-tests
    exitcode=$?
