RuboCoping with legacy: Bring your Ruby code up to Standard

  A RuboCop extension focused on enforcing Rails best practices and coding conventions.

  

  1) Auto-correcting a whole (large) codebase at once with tons of offenses and dozens of active branches should be used with caution. Merge conflicts, blame pollution (ok, can be solved with .git-blame-ignore-revs, though can hardly remember any project using it). Though, the most important argument is that auto-correct can introduce bugs. Unfortunately, even safe autocorrect can be unsafe. Recently, I broke one popular project (with a decent, but not 99.999% test coverage) with a single "safe" auto-correction commit 🙂 (This issue).

  2) Inline comments add a lot of noise. Encouraging developers to fix style issues? Or encouraging them to spend time on irrelevant fixes while working on features? The TODO approach should be considered as a prevention measure. The primary goal is to write new code in style. Unfortunately, if there are many large classes/files, TODO config can silent new offenses. To overcome this, we can use alternative tools, like rubocop-gradual.
