Re: js-clj not working
It can only handle Object objects. Check out http://stackoverflow.com/questions/16044897/why-cant-i-call-seq-functions-in-a-sequence-generated-by-js-clj 2013/5/11 nchurch nchubr...@gmail.com I'm trying to get a map out of a Goog events object (and also out of Domina events objects). Calling js-clj on either of these, even in the most recent version of cljs, doesn't seem to do anything; it just returns the inscrutable #[object Object] at the REPL. (It doesn't seem to produce maps outside the REPL either, since a console.log of a lookup on the result of js-clj returns an unimplemented protocol error.) Is there a problem with js-clj, or is there perhaps a limitation on what kinds of js objects it can handle?

Re: Why is this so difficult?
You might, BJG145, also profit by taking a look at clojurewiki.org - I'm listing there all resources I can find. Good luck! 2013/2/15 Jules julesjac...@gmail.com vemv, here is a file describing my Clojure install experience: https://www.dropbox.com/s/ln2ek5f5n47qnl1/clojureinstall.odp How should I continue? And where would a beginner find that information? Hopefully this is taken in good humor, this is meant as an illustration from a beginners' point of view, because undoubtedly the stupidity of a beginner (i.e. me) is greater than any expert can imagine. Keep in mind that once you know how to do something, doing it is easy. Driving to work is easy, but if you are in a new city then driving from point A to point B is hard if you don't know the way. The problem is the multitude of ways you can go wrong. The ideal experience would be a big download Clojure starter kit right on the clojure.org homepage, that would install leiningen, and an IDE with leiningen integration, and display a quick guide how to set up a project and run it.

On Friday, February 15, 2013 12:19:34 AM UTC+1, vemv wrote: I never tried out core.logic. This is how I just got it installed in less than a minute. Really no magic here: lein new foo; cd foo # google core.logic, grab the dependencies vector ([org.clojure/core.logic 0.7.5]), attach it to your project.clj lein repl (use 'clojure.core.logic)(run* [q] (== q true)) Same principle for practically every single Clojure lib. On Friday, February 15, 2013 12:08:18 AM UTC+1, Jules wrote: You are certainly not alone. Learning the language and concepts is very easy for me, but the sysadmin stuff to get set up is so much harder. Believe it or not, I had much more trouble with installing core.logic than understanding it. It doesn't end either, you bump into more problems once you try to do something interesting. Just try e.g. to call the LLVM C api from Clojure, I have not succeeded to this day (was trying to implement a LLVM backend for Clojurescript). You have the same problem with many open source projects, they are simply not focused on user friendliness, it's certainly not a Clojure specific problem. If you are on Windows the problems are 10x worse. Compare this with e.g. Visual Studio. You install it, and everything just works. Package manager, calling C functions, powerful GUI libraries, IDE with debugger, syntax highlighting, autocomplete, etc. From the first minute on you are programming rather than sysadmining. I wish we had the same experience for Clojure. On Thursday, February 14, 2013 7:42:57 PM UTC+1, BJG145 wrote: Having studied Lisp decades ago I like the look of Clojure a lot. But as a complete newbie when it comes to modern software development, I'm exasperated by what strikes me as a very difficult and primitive set of tools to get started. I keep seeing Leinigen, Leinigen, and the Leinigen homepage boasts that Leinigen offers the easiest way to get started with Clojure, but this simply isn't true. The easiest way to get started with Clojure that I've come across so far is IntelliJ IDEA. If I hadn't found that I'd probably have given up by now. What got me back into programming recently was a Lua-based development environment for Android called Gideros. Lua seems popular for developing apps for some reason. (Cf Corona, Moia, Unity). It seems like quite a neat language, though I'd like to use something more Lisp-like. Maybe the tools are just too difficult for me at the moment, though I'll persevere for a bit. I'd like to achieve some simple graphics on an Android device at least. I've come across some tutorials for CLojure and jMonkey and I'm wondering to dive into that, though I'm still unsure whether OpenGL is the way to go for simple 2D stuff... -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Clojure Wiki
Hello, fellow clojurians! For the next couple of months (or until I get a new functional job), I'll be working on honing my clojure skills, starting with getting a perspective of what lies *out there*: events, podcasts, guides, etc. I've created a freely-editable wiki http://clojurewiki.org, just like EmacsWiki http://emacswiki.org and CLiki http://cliki.net, for this purpose, and filled it with I already knew. There are so many cool things that I found by accident (like ClojureGazettehttp://us4.campaign-archive.com/?u=a33b5228d1b5bf2e0c68a83f4id=b25f11a98a), that I wonder how many more I am missing - and everybody is missing! - without such an iniciative. I know there is already a blog aggregator, a couple of websites with courses, a list of meetups, but no single place with everything categorized and neatly divided, which is what I'm building. I've already spent some time on the wiki so to make it worth clicking, but it's still in the beginning and much can be improved, so I invite to come around and participate in shaping it. Advertise your own tool, your own event; add a website you find particularly valuable; tell what you'd like to see! Suggestions and comments are very welcome! -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Debugging in Clojure
(comment) and #_ are pretty useful to disable forms when debugging: (+ 3 #_4) - 3 (comment println hi) - nil Excerpts from David Nolen's message of Fri Jan 22 02:38:29 -0300 2010: I find that injecting print statements is painful if you're not using something like paredit (Emacs).

I don't think I can introduce println at arbitrary places to figure out at which step is the algorithm failing. Sure you can. You might need to add a (do ) block if you're wanting to add them in an (if), but that's no different to any other form in an (if).
