Re: standalone indentation tool
I've tried pprint and found it lacking as it inserts newlines in awkward places apart from the medatada/comments issue mentioned. Are you using pprint with code-dispatch? That tends to work a lot better, though it will put newlines where it deems fit. This is either a good thing or a bad thing depending your context. It also handles all the read macros that it can: (with-pprint-dispatch code-dispatch (pprint '#(+ % 1) )) = #(+ % 1) But some get eaten by the reader and are therefore impossible for pprint to deal with (since it's working on clojure data structures and not the raw text). These are: `, ~@, ;, ^, and the comma character. I think your best bet is to use Emacs from the command-line. Even if I agree that when you're just trying to reindent human written source code, emacs is going to produce the best results. pprint is probably better for machine generated code, as long as you're not depending on the macros above. (It would also be possible to annotate your code in clojure with that and have some custom dispatch that generated those characters as appropriate.)

rebind var for all threads
There is a function in a library I am using that I want to have rebound to a
function of mine for all threads, and can't seem to figure this out, or if
it is even possible. binding, push-thread-bindings, in-ns with def, etc.
are not working, seemingly because they are only rebinding for the current
thread, but I don't know.
This is what I have tried, without success:
(clojure.lang.RT/var other-ns other-fn my-ns/my-fn)
(some-other-ns/fn-using-other-fn params)
;; still uses original binding
(push-thread-bindings {(var other-ns/other-fn) (var my-ns/my-fn)})
(some-other-ns/fn-using-other-fn params)
;; still uses original binding
(in-ns 'other-ns)
(def other-fn my-ns/my-fn)
(in-ns 'previous-ns)
(some-other-ns/fn-using-other-fn params)
;; still uses original binding
(binding [other-ns/other-fn my-ns/my-fn]
(some-other-ns/fn-using-other-fn params))
;; still uses original binding
Is what I am trying to do possible?

Small bug in clojure.core/bases?
I think I found a small bug in clojure.core/bases. Extending the
existing unit test reveals it:
(deftest test-bases
(are [x y] (= x y)
(bases java.lang.Math)
(list java.lang.Object)
(bases java.lang.Integer)
(list java.lang.Number java.lang.Comparable) )
(is (seq? (bases java.util.List
Test output is:
FAIL in (test-bases) (java_interop.clj:143)
expected: (seq? (bases java.util.List))
actual: (not (seq? #Class[] [Ljava.lang.Class;@363256a5))
When calling bases on an inteface it returns an array. Should this not
be a seq?
An easy fix though, 'seq' the else part:
(defn bases
Returns the immediate superclass and direct interfaces of c, if any
{:added 1.0
:static true}
[^Class c]
(when c
(let [i (.getInterfaces c)
s (.getSuperclass c)]
(not-empty
(if s (cons s i) (seq i))
Should I file a bug, submit a pull request, or is the behavior intended?
Cheers,
Alf

After the announcement on July 23 I immediately got excited about ClojureScript and the Google Closure toolkit, so I dropped the existing Backbone.js and jQuery code and rewrote all client-side functionality in ClojureScript. Despite (or maybe because of) the fact that the functionality is still very minimal I wanted to share this code as an example of ClojureScript in the wild. Be warned that: - this is not perfect, clean example code written by a ClojureScript expert (in several places I've used hacks and shortcuts to make things work), but hopefully at least a starting point for others working on similar functionality, - you should read the installation instructions carefully (e.g. there is still a hardcoded path in src/vix/db.clj at the time of this writing, which I hope to correct in the near future), - I'm actively developing this application, so things will change and new features will be added frequently, - the application isn't done yet, although it has a working prototype. I'm concentrating on adding features that will allow users to manage feeds (currently blog is the default feed), add media files like images and to manage users. I had trouble getting unit testing to work properly for the ClojureScript part of the application, so I grudgingly wrote it using a non-TDD approach. Retrofitting unit tests into the ClojureScript part is a priority. The user interface is also lacking some bells and whistles that I had previously implemented in jQuery, but still have to rewrite using Google Closure. Eventually, I want to turn Vix into a commercial SaaS offering, with a focus on performance (e.g. Amazon CloudFront support), scalability and webshop functionality. The application itself, however, will be perpetually available as open source software, because I'm committed to sharing my code.

Passing ClojureScript objects to JavaScript functions
What is the best way to pass Clojure vectors and maps to JavaScript functions? Currently when I need to call a JavaScript function that takes an array I do something like (js/my_js_fn (.array (vector 1 2 3))) and I pass Clojure maps like (js/my_js_fn (.strobj (hash-map a 1 b 2))) This feels a bit gross, since I'm digging into the implementation details. Is there a recommended way to do this yet? Some kind of reader macro (say @@) would be okay, turning (js/my_js_fn @@(vector 1 2 3)) into (js/my_js_fn (.array (vector 1 2 3))) at read time. Ideally though, the compiler would automatically convert ClojureScript objects into JavaScript native objects when they're passed to a function in the js/ namespace. -- You received this message because you are subscribed to the Google Groups Clojure group.

Adding ClojureScript support to a noir-based project
For what it may be worth to you: In trying out the Noir framework (which neatly assembles ring+compojure+hiccup+other stuff) for its new bindings to ClojureScript (using noir-cljs and pivot), I thought some people might like to see what kind of diff is needed to add basic ClojureScript support to a noir project. Here goes the diff on GitHub: http://goo.gl/oJjkI Note that for now, I haven't yet written a single line of ClojureScript; but if you launch the server in simple/advanced mode, you'll already be able to observe that the generated .js file is already different. In advanced compilation, it's empty. In simple compilation, it contains a few KBs of Javascript code. Since my project on GitHub is very much at its infancy for now, you might like to browse its few lines of code to see how Noir expects you to code a (very) basic website. For more information on Noir, visit its website; it's been updated by the author with nice examples. Mentioned: - Noir: http://www.webnoir.org/ - Noir-cljs: https://github.com/ibdknox/noir-cljs - Pinot (not demonstrated in my diff): https://github.com/ibdknox/pinot -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Example of a real-world ClojureScript web application
Good on you. I've been looking to find a reliable way to have Javascript unit testing run in a v8 (or any JS) shell. I've tried Jasmine and am now trying Google Closure's unit testing framework, but have so far come up short. Have you come up with anything that works? For now, i'm just having the tests run in the browser. But trying with Nodejs is the next step. Keep it up Tim On Tue, Aug 9, 2011 at 8:53 PM, Filip de Waard f...@vix.io wrote: I'm working on Vix, which is a document repository and content management system written in Clojure with a CouchDB backend. After the announcement on July 23 I immediately got excited about ClojureScript and the Google Closure toolkit, so I dropped the existing Backbone.js and jQuery code and rewrote all client-side functionality in ClojureScript. Despite (or maybe because of) the fact that the functionality is still very minimal I wanted to share this code as an example of ClojureScript in the wild. Be warned that: - this is not perfect, clean example code written by a ClojureScript expert (in several places I've used hacks and shortcuts to make things work), but hopefully at least a starting point for others working on similar functionality, - you should read the installation instructions carefully (e.g. there is still a hardcoded path in src/vix/db.clj at the time of this writing, which I hope to correct in the near future), - I'm actively developing this application, so things will change and new features will be added frequently, - the application isn't done yet, although it has a working prototype. I'm concentrating on adding features that will allow users to manage feeds (currently blog is the default feed), add media files like images and to manage users. I had trouble getting unit testing to work properly for the ClojureScript part of the application, so I grudgingly wrote it using a non-TDD approach. Retrofitting unit tests into the ClojureScript part is a priority. The user interface is also lacking some bells and whistles that I had previously implemented in jQuery, but still have to rewrite using Google Closure. Eventually, I want to turn Vix into a commercial SaaS offering, with a focus on performance (e.g. Amazon CloudFront support), scalability and webshop functionality. The application itself, however, will be perpetually available as open source software, because I'm committed to sharing my code. Here is the GitHub page for Vix: https://github.com/fmw/vix This is not a launch post for Vix, because we're not ready for supporting typical end-users yet, but I hope that the code will be useful to other developers in the meantime. I'm also happy to receive any feedback (positive as well as negative) and answer questions. You can reply to this post, but if you prefer to contact me privately you can also find my contact information on Github (https://github.com/ fmw). Sincerely, F.M. (Filip) de Waard / fmw P.S. I'd like to thank the ClojureScript developers. There are surprisingly few glitches considering that the project has only just been released. The language is incredibly well designed and a pleasure to use.

Re: tasting pinot noir
i would love to read other community-member's opinion on pinot noir ... I've gotten into these over the last week, and I've got to say, Chris is doing a very nice job on these frameworks. They are really turning into a nicely integrated offering to develop Clojure and ClojureScript web apps. Definitely worth checking out. In case you are not familiar: noir [1] = a light and simple wrapper over compojure/ring and hiccup noir-cljs [2] = middleware to add ClojureScript compilation and integration to your development pinot [3] = wrapper over some GClosure libraries, and client side hiccup templating, offering an alternative to closure templates for client and server side templates [1] http://www.webnoir.org/ [2] https://github.com/ibdknox/noir-cljs [3] https://github.com/ibdknox/pinot On Mon, Aug 8, 2011 at 6:45 AM, faenvie fanny.aen...@gmx.de wrote: recently i took a closer look at noir (http://webnoir.org) and found it a quite promising and in the words best sense minimalistic approach of a clojure-based full-stack framework for building webapps. noir is in an early stage and lacks some of the features that established frameworks like rails, django, grails have.

I've gotten into these over the last week, and I've got to say, Chris is doing a very nice job on these frameworks. They are really turning into a nicely integrated offering to develop Clojure and ClojureScript web apps. So...I've been wanting to get into using Cljs recently for a project I'm working on (porting a small Silverlight app to JS/HTML), and I wasn't sure how I wanted to setup my workflow. This is exactly what I was looking for. Being able to abstract away my async calls, routes, etc, is just awesome! Now all I need is to setup Clutch to run Clojure for my CouchDB views, and I'll have a end-to-end clojure web stack.
