standard VS plugin-ruby

Rubocop has a default rule that says to put parentheses when there are parameters; even Standardrb has a default ([https://github.com/standardrb/standard/blob/8307fa8f449f896075ccad 74bf6a128ed2c26189/config/base.yml#L1098:title])

Cynically, reading heavily between the lines, this reads to me like DHH just found out lots of rubyists like standardrb. https://github.com/standardrb/standard -- and this is his quick reaction to it.

This is a huge reason why I still use StandardJS and—shifting back to Ruby—why I rejected the countless requests for implementing line-length or any other metrics analysis rules for [StandardRB](https://github.com/standardrb/standard). There is always a legitimate edge case when it comes to length of lines and functions and the alternative—chopping them off arbitrarily—is rarely an improvement.

This approach is known as Standard Ruby. It can also be completed with plugins, including one for Ruby on Rails projects.

Oh, this is fantastic! Would you be willing to send a quick PR to our README?

If you don't want to fiddle with configuration files and the wealth of options provided by RuboCop, consider taking a look at the Standard project. It's largely a pre-configured version of RuboCop that aims to enforce a consistent style in your Ruby project without allowing the customization of any of its rules. The lightning talk where it was first announced gives more details about its origin and motivations.

Prettier started out as an opinionated code formatter for JavaScript, but it now supports many other languages, including Ruby. Installing its Ruby plugin is straight forward: add the prettier gem to your Gemfile and then run bundle.

You'd need a prettier plugin for Lua, similar to the ones that exist for php (https://github.com/prettier/plugin-php) and ruby (https://github.com/prettier/plugin-ruby). I'm pretty sure that there isn't one for Lua, but you can try googling it.

Did you try prettier maybe?

To me "stardard" ruby style is style used in the std-lib.

Whilst I can see the benefit of having an AST format code for you, e.g. if can you use it to fix language version changes like positional arguments and keyword arguments in Ruby 3,.0 I worry about how good/bad RuboCop is at formatting.

Last time I tried it, it was indenting in a different way to the std-lib.

At the time I found that prettier-ruby[1] did a much better job. Hopefully that's improved since.

Rubocop has a very nice auto-correct feature to automatically fix many of the warnings it gives, but we've noticed in the past that with line length issues specifically the auto-corrected files can be misformatted. For that reason, we use the Ruby plugin for Prettier to correct line length.
