## Ruby Best Practices - **RVM/rbenv:** Use a version manager for Ruby. - **StandardRB:** Prefer StandardRB for linting and formatting. - **Bundler:** Always use Bundler for dependency management. ## Riccardo opinionations 1. I really love the =begin/=end even if nobody uses it. In python, I love a big '''....''' Multiline at the beginning of a file explain what this file is for, and same with ruby, so I can survive this ugly =begin/=end to reach the same goal: \*\*Add a big multiline at the beginning of everything, just after the shebang and an empty line with what the app does! 2. **Minimalism** is important. 3. **Beauty** is important. If your code is minimal and beautiful, it's easier to read and to maintain. 4. Do not monkey patch unless it's the ONLY way or unless it's incredibly minimalistic/beautiful to do. 5. Riccardo likes it colorful and emojiful. I like `lolcat` and `rainbow` gems. 6. Use env ruby as shebang. 7. I don't speak JavaScirpt and friends => reduce JS to a minimum, use Ruby whenever you can, in doubt. If you have to use JS, make sure to document throughly like I was a 13yr old. ## Ruby idiosyncrasies - I love the symbols. Whenever you have a small constant string, like "foobar" use :foobar if it makes sense. - I love BLOCKs. Whenever a variable is repeated many times, feel free to use them for readability. - I tolerate =begin/-end -> but only on top of ruby files to explain what they do. ## Image Generation of Ruby Logo (NanoBanana) I find it DIFFICULT to design ruby logos, so I found two ways to create ruby logos: - **Brilliant-cut ruby** (maybe add pentagonal to it or vertical view, as opposed to aerial view which is wrong) - **Red diamond** (while more imprecise, this usually gets the job done and gets the right color!) If you experiment with this and find a better implementation which works, PLEASE ask Riccardo to piggyback it into this skill! ### Versions - Ruby 3.4+ - Rails 8.1+ ### CLIs I also love powerful CLIs with multiple options, particularly: - `-h|--help` - `-n|--dryrun` (usually disabled unless the script is DANGEROUS then should be enabled by default) - A default invocation should be SAFE, like listing, and only a further knowledgeable invocation should allow me to damage/mutate the system.
