Very good points. A codebase that gets this VERY wrong is Gitlab. I think it might be a dumb characteristic of Ruby programs, but they generate identifiers all over the place. I once had to literally give up following some code because I could not find what it was calling anywhere. Insanity.
Another point: don't use
-in names. Eventually you'll have to write them down in a programming language, at which point you have to change the name. CSS made this mistake.foo-barin CSS maps tofooBarin Javascript. Rust also made this mistake with crate names. A crate calledfoo-barmagically becomesfoo_barin Rust code.Has nothing to do with Ruby and everything to do with rails. Rails is terrible.
Funny because Rails is often touted as the main reason to use Ruby!
I've been working in Ruby on Rails lately (unfortunately) and yeah it's extremely bad at this. There's so much hidden implicit behavior everywhere.
Ruby on Rails is the worst thing to ever happen to Ruby. The language is great, much better than Python from a tooling perspective. And then Rails came along and ruined everything. I sincerely believe that the reason Python won out is solely because of Rails, because Ruby is better in every other regard.
The dash
-vs underscore_is also a common "problem" with CLI arguments--file-name, that are mapped to variable namesfile_name.Yeah, translating between cases isn't exactly a problem IME. Might be neat to have a case-aware grep though, so you can get kebab-case, snake_case, camelCase and PascalCase all done in one go.
