    A Ruby static code analyzer and formatter, based on the community Ruby style guide.

    Project mention: Thoughts on this? Blizzard replacing the word "blacklisted" with "blocklisted" in their code. | | 2021-09-19

    And if anyone doubts it's a slippery slope, see "cop" is offensive, and style guides that say to avoid using "kill", despite that being a ubiquitous term in many areas of software. Do we really want to have to bowldlerize our code into the blandest corporate family-friendly terms we can think of? If marketing want to do that to the marketing materials, sure, but I'm not interested in overanalysing my code for imagined offence

    You'll want to keep an eye on Qodana[0] which when combined with ReviewDog[1] (and some glue script since Qodana has its own snowflake output JSON that RD doesn't read natively; engineering!) can offer suggested changes on MR/PR platforms which support such a thing [2]

    I have the first two working together but not the last part yet, and Qodana is for sure a moving target but is what I've been praying for them to do for years now

    Project mention: When is it bad to use OOP? | | 2021-09-30

    So it doesn't say it isn't justified, it indicates that you might want to reconsider. So by leaving out that nuance, you're promoting this to a binary bad/wrong label which it really isn't. Also consider it's a bit obsolete in context of for example dataclasses and custom exceptions, as those often have 0 methods unless you need something extra from them. See for example complaint tickets about these and So to summarize, using a linter's best effort to indicate something that can easily be a non-issue isn't exactly the best source for programming style rules.
