Hi, I’m trying to create a POST route with compojure-api using spec. My login-params spec has login and password as strings. This: :body-params [params :- ::login-params] gives me this as a request body in swagger:

{
 "params": {
  "login": "string",
  "password": "string"
 }
}

@hoopes I know nothing about compojure-api but I wonder if you could just say :body-params ::login-params ?

yeah, that was the first thing i tried 🙂 java.lang.UnsupportedOperationException: count not supported on this type: Keyword I’ve tried a bunch of different permutations, but all result in one error or another except the line above

Sorry... ¯\(ツ)/¯

is there a better channel to ask in? it seems a little beginner-y to open an issue on the repo, unless it might cause a doc update

@hoopes I don't know. There's doesn't seem to be a channel for Compojure API although some of the Metosin projects have their own channels...

They're based in Europe so maybe asking during a time they're online (on a weekday, perhaps)... and maybe tagging one of the main contributors or maintainers?

Will do. Thanks! Appreciate it greatly

@hoopes @seancorfield I recall it's: :body [params ::login-params], the macro generates a let statement out of it. And there is #ring-swagger. Compojure-api would desperately need someone to write proper docs.

there is a nice "full" compojure-api example here to look for tips: https://github.com/yogthos/memory-hole

Hello, is there some reason in my code that these two functions have very different performances (this is in Cljs)?

(def test-file (fs/readFileSync "/tmp/test-file" "utf8"))

(let [start-time (js/Date.now)
      x (map js/JSON.parse (string/split-lines test-file))]
  (prn (str "Clj - Count: " (count x) ", Time: " (- (js/Date.now) start-time)))) ;; Clj - Count: 985, Time: 10254

(let [start-time (js/Date.now)
      x ((js/eval "x => x.split('\n').filter(x => !!x).map(JSON.parse)")
         test-file)]
  (prn (str "JS - Count: " (count x) ", Time: " (- (js/Date.now) start-time)))) ;; JS - Count: 985, Time: 774

It looks like clojure.string/split has different performance (https://cljs.github.io/api/clojure.string/split) so I’m just going to call out to JavaScript’s (.split test-file) instead

Suppose I have a map of functions like {:fn1 my.functions/fn1 :fn2 my.functions/fn2 ...} . Is there Clojure function that will invoke one of those functions in a thread first context? For example (-> (my-function-map :fn1) <invoke> (assoc :number 42)

<invoke> would call the function that resulted from the function map and, presumably, returns a map which is then threaded into the assoc.

@mafcocinco I think it would just be easier to wrap extra (..) around that first expression to invoke it.

(-> ((my-function-map :fn1)) (assoc :number 42)

that will do it. I could also bind it to a name with a let. Was more curious than anything so figured i would ask. Binding it to a name might actually be the best way from a readability stand-point, but opinions may vary.

But if you really want it in the threaded expression, I think this would do it: (-> (my-function-map :fn1) (#(%)) (assoc :number 42)) -- I just don't think that's very clear.

Or (-> (my-function-map :fn1) (as-> f (assoc (f) :number 42)))

as-> is useful inside a -> pipeline for naming something and using it in a non-first-argument way.

@mafcocinco (-> {:a (fn [] {:str "string"})} :a (apply nil) (assoc :number 42)) ?

Ooh, (apply nil) that's a nice, sneaky way of doing it!

I actually expected apply to accept 1 arg, there's no reason for it not to

yeah, trying not be clever. I think it is clearer to either invoke it on the part of the threading macro or, if that is not possible, bind it to a name.

but since it doesn't, apply nil will have to do
