Failed to open browser and the X11 DISPLAY thing… So if the app is never opened in the browser you will not get a REPL connection, since that is where the REPL runs. Can you open http://localhost:9500 manually in a browser and see if you get a REPL then?

I do that and normally I see the repl but not today

I see the html appeat and nothing else seems to happen

and no error messages in my console or the dev browser

maybe put the project on github so you can try and see what happens ? @U0ETXRFEW

Do you have an earlier commit you can try, when things worked? The answer should be in the changes since then.

nope, I deleted it and start all over again

sorry

@U0ETXRFEW any idea ?

I have only changed this method

(defn update-output [_]
    (prn "event fired")
    (cond
      (and (= \C (get-input-target))
           (= \F (get-output-target)))
      (do (set-output-temp (c->f (get-input-temp)))
          (gdom/setTextContent display-unit-target "F"))
      (and (= \F (get-input-target))
           (= \C (get-output-target)))
      (do (set-output-temp (f->c (get-input-temp)))
          (gdom/setTextContent display-unit-target "C"))
      :else
      (do (set-output-temp (get-input-temp))
          (gdom/setTextContent display-unit-target(get-input-target)))))

but i think there is nothing wrong with

It is probably something else, but you can rule out this function by making the function body empty. Seem only to be side-effecting, so already returns nil, I think…

I rule it out and it is not that

bummer, not even close to the solution

Try shortcurcuit the app so that it does nothing at all. Somewhere where it starts, do as little as possible to just ensure that you can see if it starts or not.

hmm, I have to think how to do that here

(ns learn-cljs.temp-converter
  (:require [goog.dom :as gdom]
            [goog.events :as gevents]))

(defn f->c [deg-f]
  (/ (- deg-f 32) 1.8))

(defn c->f [deg-c]
  (+ (* deg-c 1.8) 32))

(def input-target (gdom/getElement "selectInputDegreeType"))
(def temp-input (gdom/getElement "inputDegree"))
(def output-target (gdom/getElement "convertedDegree"))
(def output-unit-target (gdom/getElement "selectConversionType"))
(def display-unit-target (gdom/getElement "convertedUnit"))

(defn get-input-temp []
  (js/parseInt (.-value temp-input)))

(defn set-output-temp [temp]
  (gdom/setTextContent output-target
                       (.toFixed temp 2)))

(defn get-input-target []
  (.-value input-target))

(defn get-output-target []
 (.-value output-target))

(defn update-output [_]
    (prn "event fired")
    (cond
      (and (= \C (get-input-target))
           (= \F (get-output-target)))
      (do (set-output-temp (c->f (get-input-temp)))
          (gdom/setTextContent display-unit-target "F"))
      (and (= \F (get-input-target))
           (= \C (get-output-target)))
      (do (set-output-temp (f->c (get-input-temp)))
          (gdom/setTextContent display-unit-target "C"))
      :else
      (do (set-output-temp (get-input-temp))
          (gdom/setTextContent display-unit-target(get-input-target)))))

(gevents/listen output-unit-target "change" update-output)

Commenting out the listener registration maybe…

Tried and nothing changes

is there another way we can find the culprit?

Do you have another, similar, project that works? Otherwise create one from scratch. If that works, you know that the infrastructure works. Then “lifting” over things from the broken project, piece by small piece, should find you the problem.

oke

I can make this project again with the original code

It’s awful that you don’t get any errors anywhere. I don’t understand why that happens. I haven’t used figwheel in a long time so am not the best person to advice on that particular thing. I can only offer general advice and that I share your frustration of getting stuck like that. It’s never fun when that happens!

> I can make this project again with the original code Yeah, it is like when you are lost during orienteering. Try find your way back to the last place where you could make the map match your surroundings. To keep running while lost only gets you more lost.

A trusty friend to quickly get you back to a working state is Git. commit often.

I know

that is wierd

as soon as i copy my html to a new fresh project I see the same problem

There is nothing in there bringing in your figwheel app, I think.

you mean this part : <script src="cljs-out/dev-main.js" type="text/javascript"></script>

Yes, that part. Can’t see it in the html you pasted.

Thanks, that was it

finnaly the challenge solved

Awesome. I guess the silence from any error messages is explained as well. 😃

yep

sorry for the noise on this channel then

No problem. I am happy I could help! I don’t think it is noisy when we keep it in a thread.

good Sunday

To you as well! ☀️

here almost time for supper/dinner and then maybe see kids for halloween

Our smallest ones hope we will get some monsters visiting. We’ll see.

exactly Where do you live. I live in the Netherlands

I live in a suburb south of Stockholm, Sweden. In a residential area by a lake. It’s pitch dark outside. We don’t have any street lights on the strip outside our house. Because I like to see the stars and planets better. But it has the downside that the small monsters think it is a bit scary to visit the house, so my youngest ones don’t get many (or even any) monster visits. 😃

oke, I live in a small town in the east of the Netherlands

today 3 kids ;'(

Just checked it out, the clojureDocs integration is awesome! is there any way to increase the hover space(or maybe have the docs in a new file itself?)

The hover are a bit tiny and flickery for this, unfortunately. You can use the commands for printing the examples to rich comments or the output window to get more room, and also play with the examples in the REPL.

If you haven’t upgraded Calva to 2.0.223, you should. Because this is now released, and there are some improvements since this VSIX. See #announcements
