Extra optional attr-map argument on defn... why?

In a private chat (I will not expose their names, but they may feel free to identify themselves in this thread) someone posed a question: Anyone know why the multi-arity version of `defn` takes an extra optional `attr-map?` argument? https://github.com/clojure/clojure/blob/clojure-1.10.1/src/clj

Hi folks I've released 0.1.0 of defn-spec <https://github.com/danielcompton/defn-spec>, a library that lets you define your function specs inline with your function definitions. A quick example, defn-spec lets you write: (ds/defn to-zoned-dt :- ::zoned-date-time [instant :- ::inst

No, we don't plan to add that. We think there is a lot of value in having them independent. Rather than add it to the guide, I would prefer to add a section to the FAQ page. I've been to do so, but haven't gotten around to it yet. -- You received this message because you are subscribed to the

defn with inline specs?

Currently I don't think it's possible to include a spec inline with a function definition. If you want to spec a function, it needs to come afterwards in an s/fdef. Is it planned for defn to have an extension to allow inline specs, similar to how pre and postconditions are defined

I defined my own defn in the namespace mwm. My new code looks like this (mwm/defn foo [x] ...) Everything was fine as long as it was called defn2, but after renaming it to defn and refering to the original defn using clojure.core/defn, only "lein uberjar" works. When I run

x27;s inside other def's are _not_ local. In your example, you will find after defn'ing double-square with the defn square inside that later you can call not only double-square from other functions, but also square, because the defn makes it globally visible (in that namespace, and any oth

Re: Cheap way to find function (defn) name using a macro?

Since you want to use the plain defn, what about thinking in a different way ? Write a macro like `with-function-name`, wraps the function call instead of the function definition. (defmacro with-function-name [fn-name args] ...) In clojure, because you can assign function to a var at any
