Code formatting is an opinionated beast. It always has been a matter of taste, and it always will be a matter of taste. This is the reason, why professional formatting tools, such as Eclipse JDT, offer a gazillion number of options. Which is still not sufficient enough. After all, you can override them inline with tag-comments to make the formatter shut up. Can't we do better than that? What if we could use machine learning techniques to detect the preferred code style that was used in a codebase so far? Turned out, we can.
