Wrong Clojurescript REPL URL

Community Center Beginners
1

I was following ClojureScript - Quick Start and just started a small clojurescript project.

But, my REPL and browser were on different machines, I started the REPL by:

$ clj -M --main cljs.main --repl-opts "{:launch-browser false :port 8091 :host \"100.64.0.32\"}" --compile cljs01.core --repl
Waiting for browser to connect to http://100.64.0.32:8091 ...
ClojureScript 1.11.54
cljs.user=>

And on the other machine, I opened http://100.64.0.32:8091 with my browser, I could see the webpage, but there was a request directing to http://localhost:9000/repl?xpc=%7B..., I think this URL may be the default URL listened by the server side? Why didn’t the --repl-opts change it?

Waiting for replies in eagerness, Thanks.

Can’t reproduce it with 1.11.132.

I’d try refreshing the browser page with removing all cache (in Chrome you can do it by opening the DevTools and then holding the Refresh button in the main browser panel, then selecting the Empty Cache and Hard Reload option).

I disabled the cache in the browser dev tools and upgraded clojurescrpt from 1.11.54 to 1.11.132, but the issue is still there…

and the query string of the request to http://localhost:9000/repl is:

xpc={"cn":"JjBpKU5zry","tp":null,"osh":null,"ppu":"http://100.64.0.32:8091/robots.txt","lpu":"http://localhost:9000/robots.txt"}

I am not sure if this helps for solving the issue.

Ah, wait - I actually can reproduce it but only if I also provide the --compile option. Starting a plain REPL works just fine and uses the specified host/post.

Thank you, so it’s a bug? If so, could you or someone else help create an issue? I have no permission to file an issue on JIRA.

Also, I get this:

$ ag 9000 out/
out/clojure/browser/repl.cljs
32:(goog-define PORT 9000)

out/clojure/browser/repl.js
27:clojure.browser.repl.PORT = goog.define("clojure.browser.repl.PORT",(9000));

$ ag localhost out/
out/clojure/browser/repl.cljs
31:(goog-define HOST "localhost")

out/clojure/browser/repl.js
22:clojure.browser.repl.HOST = goog.define("clojure.browser.repl.HOST","localhost");

Same on my boxes, REPL without --compile xxx works.

I think I figured it out. This is what I’ve reported on Slack in the #cljs-dev channel:

What I assume is going on is that without the --compile option, the third cond branch in cljs.repl.browser/send-static gets executed, the one with the ;; "/main.js" doesn't exist, provide our own comment, and it sets a custom CLOSURE_UNCOMPILED_DEFINES .
But with the --compile option, the first branch gets executed, and it doesn’t use :host /:port by itself. Perhaps, those parameters also don’t get compiled into main.js , which results in the issue.

As a workaround, you can add these arguments to the CLI, in addition to --repl-opts:

--compile-opts '{:closure-defines {clojure.browser.repl.HOST "100.64.0.32" clojure.browser.repl.PORT 8091}}'

(Note that you don’t have to escape " if the outer quotes are '.)

That works, thank you in advance!

It’s tracked under [CLJS-3416] - JIRA.
