Hello, I’d like to have a printf-like function, that prints a newline after each message. Here is one of my attempts (which doesn’t even compile): let warn fmt = Printf.eprintf (fmt ^ "\n") let () = let fname = "abc" in let lnum = 123 in warn "%s:%d: hello world" fname lnum Any suggestion…

Printf with automatic '\n'

Just replace ^ (string concatenation) by ^^ (format string concatenation): let warn fmt = Printf.eprintf (fmt ^^ "\n").
