The main difference I’ve noticed is the consistent use of “” for all strings vs. only using “” for strings that are doing interpolation. I got started on the latter, so my fingers seem to prefer using ‘’ for strings unless interpolation is needed.
I think it’s important to just find style guidelines you and your teammates can agree on, and then to stick to it. There’s parts of the Github, BBatsov/Rubocop and Thoughtbot style guides that I like, and parts I don’t. Just find things that work for you, and pay attention to when people that you respect do things differently, because there might be a good reason why.
fwiw, I prefer rubocop. I use guard-rubocop which I think is a great way to ensure the aesthetics of the code throughout the system. I did disable the 80 character line-limit and the top level comment (I hate writing comments).
Like you I like the ‘’ for strings that don’t have interpolation. I just think it looks nicer.
I still prefer to say what I mean and mean what I say (PoLS)…
immutable_str = 'something cool here'
interop = "#{immutable_str}, how awesome is that?"
I will freely admit this comes from back when i did ASP.Net work and strings were killing app performance due to garbage collection. Since then i have been careful about what kind of string i use.
I am also into ruby-functional coding, so I prefer values and idempotency. To me, this style of stringing goes along with that, as well as PoLS.
