Мы используем отличный инструмент CS-Script для наших ловушек перед фиксацией, чтобы мы могли писать скрипты на языке, на котором мы разрабатываем. Вот пример, который гарантирует, что сообщение фиксации длиннее, чем 10 символов и гарантирует, что файлы .suo и .user не будут проверены. Вы также можете проверить наличие отступов табуляции / пробела или выполнить небольшие стандарты кода при регистрации, но будьте осторожны, чтобы ваш скрипт делал слишком много, как вы не хочу замедлять коммит.
