live-cljs code for the dojo

[Richard]

I checked out the live-cljs code to prepare for the dojo, but it hit an exception when I ran it. Has anyone had a similar issue?

I checked out https://github.com/ibdknox/live-cljs.git

And after "lein run" it throws an exception:

Exception in thread "main" java.lang.RuntimeException: java.lang.AssertionError:

 Assert failed: Can't recur here

Yes, you have to do

rm -rf target/classes/cljs

to fix it.

I have the demo running at http://bristolclojure.herokuapp.com so that beginners can just play with that instead of worrying about setting up lein, light table etc. It doesn't seem to work as well on Firefox as with Chrome, though.

It's doing it on the first run, so nothing already existed in the
target directory.
I'm also doing it on a Windows machine -- that can't be the problem, can it?

[Matt Thompson]

Hi Richard,

I've forked the project on github and applied a fix that seems to be working (at least on my Linux machine). Can you try it on your Windows box and see if it works?

Thanks Matt
I can confirm that your version https://github.com/cblop/live-cljs
works for me. How did you find the fix?

It was on a Google groups discussion somewhere. It involved removing some files somewhere in the project.

I'm now playing around with the WebGL Clojurescript game engine Chocolatier: https://github.com/alexkehayias/chocolatier. It's a bit tricky to get running, but it works.

Hi.

I had a look at Chocolatier but could not get it running... is there a particular version of clourescript I need ?

Do you remember how you got it working ?

Thanks.

[Matthew Thompson]

I have to admit, it's been a while since I looked at Chocolatier, so it's probably changed a lot since I last used it.

I have used play-clj recently, though, which is very promising. It's more or less an interface to libGDX, but allows you to write game code in a very idiomatic Clojure-y way: https://github.com/oakes/play-clj

If you have any questions about getting that working (it is much easier to get running!), then I'm happy to help.
