I like to enforce code style because I use automated-formatting on all the files I change.  So, to avoid useless lines in git diff we have everybody use the same settings in their IDE to make sure we don&#x27;t have to go through a bunch of &quot;tab to space&quot; changes.<p>I personally don&#x27;t care much for style per se (e.g. should I leave an empty line after each class declaration and garbage like that).  The only one I like: no lines longer than 80 characters, simply because I occasionally work on small laptops and like being able to see the whole line at once.
