how would i configure lein to copy the static assets (imgs, css, etc) to the output directory of cljsbuild?

Does anyone know what Google means by "2D array" in this? https://google.github.io/closure-library/api/goog.fx.dom.Scroll.html

henrik10:04:08

start	(Array<number>|null)
2D array for start scroll left and top.

henrik10:04:41

Looks decidedly one dimensional to me, but it fails silently, so I'm guessing I have something wrong.

victorb10:04:42

guessing it's a array with two coordinates, x y which would be the pixels from the left and the pixels from the top (but, this is a guess)

victorb10:04:54

should be used something like this: goog.fx.dom.Scroll(document, [0,0], [0,100], 200);

victorb10:04:42

well, (new goog.fx.dom.Scroll(document, [0,0], [0,100], 200)).play() I guess would be the full usage actually

henrik10:04:43

This is what I have:

(let [el (get-element "the-element")
      scroller (Scroll. el
                       (clj->js [0 800])
                       (clj->js [0 (.-offsetTop el)])
                       200)]
   (.play scroller))

I'm guessing the problem is somewhere else then. Alright, thanks!

I gave up on Closure and just used .scrollIntoView.

I’m working through Ch7 of living clojure and I think I’m getting tangled up in version dependencies The book is written circa 2015 pardon the length of this output cljsbuild barfout my cheshire-cat.core file core.cljs

(ns cheshire-cat.core
  (:require-macros [cljs.core.async.macros :refer [go]])
  (:require [clojure.browser.repl :as repl]
            [cljs-http.client :as http]
            [cljs.core.async :refer [<!]]
            [enfocus.core :as ef]))

(defn ^:export init []
  (repl/connect "")
  (go (let [response (<! (http/get "/cheshire-cat"))
            body (:body response)]
        (ef/at "#cat-name" (ef/content (:name body)))
        (ef/at "#status" (ef/content (:status body))))))

my project version dance

Hey @UHVRM4S64, did you get yourself sorted here?

zane06:04:29

The issue I believe you're running into is that since that book was written the ns macro became more strict about its arguments.

zane06:04:28

In particular inside a ns form (:import [package.Class]) used to work, even though it's malformed (import lists expect a space between the package name and the class name(s) (:import [package Class])).

zane06:04:28

One of the packages you're using, enfocus, has a namespace (`enfocus.macros`) that uses that malformed syntax: https://github.com/ckirkendall/enfocus/blob/master/src/clj/enfocus/macros.clj#L5).

zane06:04:19

One thing you could try is downgrading your Clojure version to when the ns macro was less strict. 1.9.0, say.

zane06:04:58

I filed an issue for the malformed ns form in enfocus.macros here: https://github.com/ckirkendall/enfocus/issues/111

Tangible Dream13:04:34

I was thinking of downgrading. I’ll try it

Tangible Dream13:04:07

Here is what I get with 1.9.36

@UHVRM4S64 The relevant bit there is this part:

Call to clojure.core/ns did not conform to spec.

Try going back farther.

Tangible Dream20:04:20

Actually, the writer of enfocus is going to get his code up to current versions

zane20:04:56

Oh, great!
