Compatible with latest CLJS/REPL stuff?

[brandonparsons]

Sorry for the poorly titled issue.... I'm struggling my way into the CLJS ecosystem :)

Getting the following error after trying to launch a CLJS REPL with Weasel/Piggieback:

Calling function was:

(defn browser-repl []
  (let [weasel-repl-env (weasel.repl.websocket/repl-env :ip "0.0.0.0" :port 9001)]
    (cemerick.piggieback/cljs-repl {:repl-env weasel-repl-env})))

[cichli]

I think that should be (cemerick.piggieback/cljs-repl :repl-env weasel-repl-env) (i.e. keyword arg rather than options map), unless you're using piggieback 0.2.0-SNAPSHOT, in which case: (cemerick.piggieback/cljs-repl weasel-repl-env).

[brandonparsons]

@cichli I am trying to use 0.2.0-SNAPSHOT, and changed it to (cemerick.piggieback/cljs-repl weasel-repl-env).

My particular error went away, but now I'm getting a new one....

My client-side code that goes along with this:

(ws-repl/connect "ws://127.0.0.1:9001"
                 :verbose true
                 :print #{:repl :console}
                 :on-error #(print "Error! " %))

I have tried using 127.0.0.1 and localhost and get various errors. I'm wondering if I'm doing something totally wrong.

On the client side I"m seeing:

WebSocket connection to 'ws://localhost:9001/' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED
repl.cljs:80 WebSocket error goog.net.WebSocket.ErrorEvent {type: "error_1", target: goog.net.WebSocket, currentTarget: goog.net.WebSocket, propagationStopped_: false, defaultPrevented: false…}
core.cljs:116 Error!  #<[object Object]>
repl.cljs:75 Closed Websocket REPL connection

[tomjakubowski]

Sounds like something in piggieback is trying to eval during the -setup phase. Weasel really needs to block until a client connects for it to work properly. There's an open issue at #51 that now must be fixed.

Gotcha. Will keep an eye on both!

[tomjakubowski]

@brandonparsons if you weren't scared off by how everything in REPL land is always breaking (sorry!), did you manage to try out one of the newer Weasel snapshots?

[brandonparsons]

@tomjakubowski I did get a tad scared away (don't worry - I understand everything is in flux right now!), and this was just a bit of a side project.

Whenever I do pick up CLJS again, I will be giving this another shot :)

I will close this issue for now!
