Programming clean remote6/29/2023 ![]() To compute the maximumBy, you need an ordering function and a list, and the result is an element of that list. ![]() That's a theoretical structural concept that transcends programming paradigms.Įxpressed in Bob Martin's "TO paragraph" format, I read your example as: The important part is the grouping of functionality at the same level of abstraction, in a logical progression. He doesn't mean the code should read like English. Paragraphs, as he describes them, do not require long-windedness. I'm not sure I follow what you mean by your example. I suspect that Haskell written to the standard of Clean Code would come off as long-winded and unnatural.Īm I wrong to consider (at least some of) Clean Code at odds with functional programming best practices? Is there a sensible way to reinterpret what he says in a different paradigm? ![]() Unlike the Java examples in his book, I can't imagine any way to refactor that in to something that has the sort of cadence he asks for. That is about as far away as you can possibly get from Martin's advice, but that's concise, idiomatic Haskell. MaximumBy _ = error "List.maximumBy: empty list" Taking an example out of the Haskell standard library: maximumBy :: (a -> a -> Ordering) -> -> a Martin's examples in the book definitely do read as if they were a set of paragraphs, and they're very clear - but I'm not so sure that "reads like a set of paragraphs" is a desirable quality for functional code to have. In either case we render the page in HTML TO RenderPageWithSetupsAndTeardowns, we check to see whether the page is a test page and if so, we include the setups and teardowns. ![]() "To do X, we perform steps Y and Z." "To do Y, we." etc.) For example: ( Clean Code, page 37: a "TO paragraph" is a paragraph that begins with a sentence voiced in the infinitive. Of TO paragraphs, each of which is describing the current level of abstraction and referencing subsequent TO paragraphs at the next level down. It's best summed up by this quote:Į want to be able to read the program as though it were a set In particular, I think his advice to use small functions with meaningful names makes my code flow much more smoothly. I think it's great, and when writing OO code I'm taking his lessons to heart. I'm currently reading Robert Martin's Clean Code.
