Ameba: Rubocop for Crystal Language
Ameba seems like quite mature linter for Crystal language. As I start my first real world code in Crystal language, the real tools are very useful. (Side note: I didn’t write any non-real-world crystal code. I’m not sure it helps. REPL sessions are not code. they don’t count) It automatically uses built-in formatter in the --fix mode. There is also awesome emacs integration as well. Check ameba.el
