any reason this commands doesn't return a repl? clj -m cljs.main -H '0.0.0.0' -p 8080 -ro '{:launch-browser false}' -c hello-world.core -r

the browser connects fine and displays https://clojurescript.org/images/content/guides/quick-start/browser.png

@lockdown- you can't use -c together with -r

oh hrm, I guess you can, I keep forgetting we tweaked that to work together - do you see any errors in the browser JS console?

(also I'm assuming this works for you if you don't use any of the options)

@dnolen in the console I get an error connection refused for http://localhost:9000/repl?xpc=%7B%22cn%22%3A%22FSbb3twDOo%22%2C%22tp%22%3Anull%2C%22osh%22%3Anull%2C%22ppu%22%3A%22http%3A%2F%2F3.19.55.194%3A8080%2Frobots.txt%22%2C%22lpu%22%3A%22http%3A%2F%2Flocalhost%3A9000%2Frobots.txt%22%7D

took out the port flag and used default port 9000

this is from a remote browser btw, hence the flags

The issue is localhost is hardcoded here https://github.com/clojure/clojurescript/blob/master/src/main/cljs/clojure/browser/repl.cljs#L31

Can anyone point me at a compare function that can be used to to sort mixed types?

I am looking to compare strings, numbers, booleans and keywords.

Something along the lines of (defn safe-compare [x y] (if (or (identical? (type x) (type y)) (and (number? x) (number? y))) (compare x y) (let [type-preced #(cond (number? %) 0 (string? %) 1 (boolean? %) 2 (keyword? %) 3 :else 4)] (< (type-preced x) (type-preced y)))))

@lockdown- You should be able to override that by adding -co '{clojure.browser.repl/HOST "my-host"}' to your command line

Hello guys, I try to make react-beautiful-dnd work with shadow-cljs but it doesn’t seem to work. I imported react-flatpickr that worked fine.

@lockdown- @mfikes and I believe that's actually done

there is some cljs.core function equivalent to js/Array.from ?

@mfikes @dnolen just tried that, the browser still tries to request the file from localhost

btw, if a host is not specified, the web server still accepts remote connections

@lockdown- try removing your output directory and try again

yeah, did that before trying the compiler option but requests from localhost

Hi all, I’m trying to pretty print a piece of EDN but for some reason the CLJS compiler is saying pprint doesn’t exist:

(with-out-str (cljs.pprint/pprint {:foo 1}))

Use of undeclared Var cljs.pprint/pprint

What am I missing?

have you required cljs.pprint ?

I should need to?

cljs.user=> (require '[cljs.pprint :as pprint])
nil
cljs.user=> cljs.pprint/pprint
#object[Function]

Given I’m using a fully qualified name

yes. you need to require anything not in core

welll... it's way more complicated than that. but that's the way to think about clojure namespaces at least

kk, thanks

np

Is there a good resource for clj -> cljs ns and fn mapping?

@mruzekw not really, but it's not needed we auto-alias them anyway

require clojure.pprint will just load cljs.pprint

Oh! That’s neat

Thanks for the tip

@lockdown- it's possible it's just a bug - the standard browser REPL is mostly used for testing, not quite enough there yet for serious development

whatever it is that you want to do you can definitely do with something like Figwheel which is much more mature due to the number of users

@dnolen oh, I see, looks like the browser repl in cljs is a complex subject (compared to clojure). Using just --watch (and my own web server) and refreshing the browser has been enough for playing with cljs for now, will look into figwheel next.

is --watch considered reliable? 😉

unlikely to change, works ok - not quite as fancy as Figwheel again

How would I go about doing incremental compilation manually? (without watch)

nm, will take a look at http://cljs.github.io/api/cljs.build.api/watch

Can somebody share Selenium tests for cljs? What library do you use? Do you recommend something else, than selenium? Do you even code this tests in cljs? I did research about this a long time ago. I am not up to date.
