--- title: Why Does Style Matter? teaser: Working in a well-organized code base is like cooking in a clean kitchen. tags: web,productivity,hound author: Matt Sumner published_on: 2015-02-12 --- A few days ago, our [Hound](https://houndci.com/) team asked a question that gave me pause: "Why does style matter? If we were to stop using style guides on all of our projects, what would your argument be for bringing them back?" This reminded me of a recent client engagement. I found myself in a delicate situation while integrating with an existing developer team: They were not accustomed to following a style guide while working on a project. When we first pitched the benefits of introducing a style guide to the code base it appeared the whole team was on board. > Having a style guide makes a code base feel neat. It gives the impression of > a team working well together towards a common goal, rather than individual > developers working frantically and without purpose. > > Working in a well-organized code base is like cooking in a clean kitchen. If > things feel messy, it's easy not to treat it with respect. If the formatting > feels sloppy, it will tempt you to also be sloppy when it comes to > readability, dependency management, and testing. > > Inconsistent formatting is the first sign of a code base that nobody really > cares about. > > Joe Ferris However, in practice, the team was not on board with a style guide. During code review developers defended each style violation as a special case. This tension was magnified by the fact that pull requests and code reviews were only introduced shortly before the style guide. We went through the exhausting process of searching through pull requests for style violations and then having to explain the reasoning behind each guideline. This exercise made me feel awful and wasted time we could have spent developing features. > I hate doing work that can be automated.

When the team learned that a robot dog was going to start reviewing their code, their attitude completely changed. Instead of arguing about the style choice everyone simply made the changes. After all, it would be silly to be offended by a bot!

You know, having Hound on OSS is really nice. I can point to it for style problems without feeling like a jerk.
