Hey all, I have been experimenting with clojurescript and following the modern tutorial.
However I am now stuck while trying to get the browser repl (brepl) working. I looked on the clojurescript jira tracker and there was no mention of this problem. There was no way to add an issue, so I thought I would post here as this is what is mentioned on the clojurescript page. This issue means no brepl, which pretty much brings any further investigation of clojurescript to a halt. Thanks in advance for any help. Rohan The details: I was following this tutorial: https://github.com/magomimmo/modern-cljs/blob/master/doc/tutorial-02.md I have a static web server running, I get a repl by executing: lein trampoline cljsbuild repl-listen And then I go to the simple.html page being served up by my server: http://localhost:8888/simple.html At this point according to the tutorial I should be good to go, and the repl from the cljsbuild command given in the terminal earlier should work. However, it hangs, and so I opened the console and saw these errors. Uncaught TypeError: Cannot call method 'call' of undefined on line 989 of repl Which is actually caused by: Uncaught TypeError: Cannot read property 'client' of undefined on line 1021 of repl The source comes from this url: http://localhost:9000/repl?xpc=%7B%22cn%22%3A%22ScD89D6Sbo%22%2C%22tp%22%3Anull%2C%22osh%22%3Anull%2C%22ppu%22%3A%22http%3A%2F%2Flocalhost%3A3000%2Frobots.txt%22%2C%22lpu%22%3A%22http%3A%2F%2Flocalhost%3A9000%2Frobots.txt%22%7D which after some grepping is coming from: <project root>/repl/client.js And sure enough if I go to the offending line I see this: </script><script type="text/javascript"> clojure.browser.repl.client.start("http://localhost:9000";); Uncaught TypeError: Cannot read property 'client' of undefined </script></body></html> evaluating the clojure object indeed gives us clojure.browser.repl but the repl object has no client. I started looking into this in more depth and found that indeed the code that defines a client and the start function which is found one line up: clojure.browser.repl.client={}; clojure.browser.repl.client.start=function(a){ return goog.events.listen(window,"load",function(){ return clojure.browser.repl.start_evaluator.call(null,a) }) }; The ...repl.start_evaluator exists, and looks like this: clojure.browser.repl.start_evaluator=function(a){ var b=clojure.browser.net.xpc_connection.call(null); if(cljs.core.truth_(b)){ var c=clojure.browser.net.xhr_connection.call(null); clojure.browser.event.listen.call(null,c,"\ufdd0'success",function(a){ return clojure.browser.net.transmit.call(null,b,"\ufdd0'evaluate-javascript",a.currentTarget.getResponseText(cljs.core.List.EMPTY)) }); clojure.browser.net.register_service.call(null,b,"\ufdd0'send-result",function(b){ return clojure.browser.repl.send_result.call(null,c,a,clojure.browser.repl.wrap_message.call(null,"\ufdd0'result",b)) }); clojure.browser.net.register_service.call(null,b,"\ufdd0'print",function(b){ return clojure.browser.repl.send_print.call(null,a,clojure.browser.repl.wrap_message.call(null,"\ufdd0'print",b)) }); clojure.browser.net.connect.call(null,b,cljs.core.constantly.call(null,null)); return setTimeout(function(){ return clojure.browser.repl.send_result.call(null,c,a,clojure.browser.repl.wrap_message.call(null,"\ufdd0'ready","ready")) },50) } return alert("No 'xpc' param provided to child iframe.") } There is no obvious place where this goes wrong within the start_evaluator, as all the methods that are called, exist. So here is the function (prettyfied) where the error occurs. Uncaught TypeError: Cannot call method 'call' of undefined on line 989 of repl clojure.browser.net.connect=function(){ var a=null, b=function(a){ var b; b=a?a.clojure$browser$net$IConnection$connect$arity$1:a; if(b) return a.clojure$browser$net$IConnection$connect$arity$1(a); b=clojure.browser.net.connect[goog.typeOf(null==a?null:a)]; if(!b&&(b=clojure.browser.net.connect._,!b)) throw cljs.core.missing_protocol.call(null,"IConnection.connect",a); return b.call(null,a) }, c=function(a,b){ var c; c=a?a.clojure$browser$net$IConnection$connect$arity$2:a; if(c) return a.clojure$browser$net$IConnection$connect$arity$2(a,b); c=clojure.browser.net.connect[goog.typeOf(null==a?null:a)]; if(!c&&(c=clojure.browser.net.connect._,!c)) throw cljs.core.missing_protocol.call(null,"IConnection.connect",a); return c.call(null,a,b) }, d=function(a,b,c){ var d; d=a?a.clojure$browser$net$IConnection$connect$arity$3:a; if(d) return a.clojure$browser$net$IConnection$connect$arity$3(a,b,c); d=clojure.browser.net.connect[goog.typeOf(null==a?null:a)]; if(!d&&(d=clojure.browser.net.connect._,!d)) throw cljs.core.missing_protocol.call(null,"IConnection.connect",a); return d.call(null,a,b,c) }, e=function(a,b,c,d){ var e; e=a?a.clojure$browser$net$IConnection$connect$arity$4:a; if(e) return a.clojure$browser$net$IConnection$connect$arity$4(a,b,c,d); e=clojure.browser.net.connect[goog.typeOf(null==a?null:a)]; if(!e&&(e=clojure.browser.net.connect._,!e)) throw cljs.core.missing_protocol.call(null,"IConnection.connect",a); return e.call(null,a,b,c,d) }, a=function(a,g,h,i){ switch(arguments.length){ case 1:return b.call(this,a); case 2:return c.call(this,a,g); case 3:return d.call(this,a,g,h); case 4:return e.call(this,a,g,h,i) } throw Error("Invalid arity: "+arguments.length); }; a.cljs$lang$arity$1=b; a.cljs$lang$arity$2=c; a.cljs$lang$arity$3=d; a.cljs$lang$arity$4=e; return a}(); I have not managed to walk through this as the debugger considers the xpc material new every time so breakpoints get discarded on each refresh.
