I'm using 100% ClojureScript, with Google Closure as the only external dependency. I don't miss Backbone.js, because it's design makes less sense with ClojureScript than it does with JavaScript (i.e. it is based on the JavaScript OOP paradigm). I used what I learned from Backbone.js while writing my ClojureScript code. I copied the idea of a routes function that generates views based on the URI. I use this routing method to generate views without reloading the page, using an event listener and the goog.history.Html5History module. One of my favorite aspects of Backbone.js is Underscore.js, which brings Lisp functions like filter, map and reduce to JavaScript, but this is clearly redundant in ClojureScript. Backbone.js is not something I would use with ClojureScript, but it is definitely designed by smart people and it is a useful source of inspiration when building client-side applications. Have you shared any code between the frontend and backend? As in run the same functions on both sides. If so, are you duplicating the code in both .clj and .cljs or doing something else Vix has three quite separate components: the visitor-facing presentation layer (flat HTML pages that are used as Enlive templates and CSS), the Clojure backend (basically a document repository with a JSON API) and the ClojureScript client-side code. The client-side code, including it's templates, is fully written using the Google Closure tools and ClojureScript, so there is almost no overlap. Off the top of my head I can think of a single utility function that I copied between the ClojureScript and Clojure parts. As far as I'm aware it is not possible to share code by other means than copying yet, because there are some practical barriers for interoperability. How has the debugging/error notification experience been? The stack traces aren't always very informative, so some things took a while to figure out. This was usually my own fault, because I skimmed over something important in the docs, for example, but it wouldn't hurt if it was easier to figure out what was going wrong. I suggest using the generated JavaScript as the starting point for debugging. My process is pretty much to check if the JavaScript output looks correct and use the debuggers in Firefox and Gnome if that doesn't help. I've also used the occasional (js/console.log) call and even edited the generated JavaScript on occasion to figure out the root of a particularly nasty problem. - fmw -- You received this message because you are subscribed to the Google Groups Clojure group.

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. I don't have it at hand, right now, because I'm not at home, but I think the Google Closure book suggests using Selenium to automatically run the tests. Alternatively, using script/repljs might work. Do you have the tests running a browser window already? If so, I'd love to have a look at how you did that, because I haven't gotten that far yet myself. I'm going to give this another shot soon, because I've learned quite a lot about ClojureScript since I last tried to get testing to work. -fmw 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.

[ANN] Lacij v.0.4.0
Hello, I'm pleased to announce the release of the version 0.4.0 of the Lacij graph visualization library. The release includes a new automatic layout called hierarchical layout. It is similar to a tree layout or family tree but works on any type of graph (tree or not). An example of this layout can be seen here http://minus.com/ll9M1g it is a PNG exported from the generated SVG. The release also extends the API and fixes a couple of bugs. The library is available on GitHub: https://github.com/pallix/lacij and Clojars: http://clojars.org/lacij Please get in touch if you want to help the Lacij project and implement additional layouts algorithms. From the README: Lacij is a graph visualization library written in Clojure. It allows the display and the dynamic modification of graphs as SVG documents that can be viewed with a Web browser or with a Swing component. Undo/ redo is supported for the dynamic modification. Automatic layout is provided for the visualization. -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: rebind var for all threads
(This is all moot at this point, since the author or Noir has made changes that allow it to be compatible with App Engine.) Background: This was with noir version 1.1.0, and appengine-magic version 0.4.3. appengine-magic needs a ring handler, which noir provided with noir.server/gen-handler. However, that handler had a bunch of default middlewares added by compojure.handler/site. One of those middlewares was the ring multipart-params middleware, added by ring.middleware.multipart-params/wrap-multipart-params. This middleware uses java.rmi.server.UID, which is not an allowed class on app engine. For that reason, appengine-magic already has a replacement in appengine-magic-multipart-params/wrap-multipart-params. What I was trying to do was re-bind the var that was bound to the ring middleware, instead binding it to the appengine-magic replacement, for all threads executing the servlet. Since this runs on app engine, who knows which thread initializes the servlet, who know which threads are executing the code on each request, etc. A couple methods worked in the repl, and in local testing, but not in the live app engine environment. I believe this may be one of those, but I tried so many things it is hard to remember: Code: (ns test-site.core (:require [appengine-magic.core :as gae] [noir.server :as server])) (defn handler [] (binding [ring.middleware.multipart-params/wrap-multipart-params appengine-magic.multipart-params/wrap-multipart-params] (server/gen-handler))) (gae/def-appengine-app test-site-gae (handler)) Relevant code files, if you want to look, but this is all moot at this point: ring.middleware.multipart-params = https://raw.github.com/mmcgrana/ring/8dc40e8f38c59c9a1275991d7b7522b620b3a180/ring-core/src/ring/middleware/multipart_params.clj compojure.handler = https://raw.github.com/weavejester/compojure/master/src/compojure/handler.clj noir.server = https://raw.github.com/ibdknox/noir/master/src/noir/server.clj appengine-magic.multipart-params = https://raw.github.com/gcv/appengine-magic/master/src/appengine_magic/multipart_params.clj On Thu, Aug 11, 2011 at 10:43 AM, Armando Blancas armando_blan...@yahoo.com wrote: My code calls a function in 3rd party library A, which in turn calls a function in 3rd party library B.

At the very least there should be nice functions to call to convert back and forth explicitly, if automatic conversion is out and a reader macro will only work for compile time constants.

Or is such a function already there, but considered annoying enough to want to be able to hide it in implicit conversions or short, pithy reader macros? Of course, in the latter case, a reader macro that expands to the function call could work on non-constants, though, as @foo already expands to (deref foo) in normal Clojure and does not require foo to be a compile time constant. -- Protege: What is this seething mass of parentheses?!

Yeah, I ended up writing two such functions for converting Clojure sequentials into JS arrays and maps into JS objects: https://gist.github.com/1141054 (Note that they won't convert a vector containing maps or vice versa properly, so they're not quite nice functions yet.)

Do you know why an automatic solution is out? I'm trying to use D3 from ClojureScript, but right now all of the clarity I get from Clojure's nicer data manipulation abstractions is lost having to convert to/from JS objects everywhere. At the very least there should be nice functions to call to convert back and forth explicitly, if automatic conversion is out and a reader macro will only work for compile time constants. So one could use @@the-structure for constants, and (to-js the-structure) for anything else, or something of the sort. Or is such a function already there, but considered annoying enough to want to be able to hide it in implicit conversions or short, pithy reader macros? Of course, in the latter case, a reader macro that expands to the function call could work on non-constants, though, as @foo already expands to (deref foo) in normal Clojure and does not require foo to be a compile time constant. -- Protege: What is this seething mass of parentheses?!

Re: rebind var for all threads
Is the app store for more than just Android device apps then? Apple has one central app store for iPhone/iPad apps, and now even has one for Mac apps. Android's situation I haven't exactly figured out, but I think there is a central app store somewhat managed by Google, but Amazon also has an app store for Android, and I don't know if there are others, or if any carriers have their own stores. - Mark On Thu, Aug 11, 2011 at 9:48 PM, Ken Wesson kwess...@gmail.com wrote: On Thu, Aug 11, 2011 at 5:47 PM, Sean Corfield seancorfi...@gmail.com wrote: On Thu, Aug 11, 2011 at 2:10 PM, Ken Wesson kwess...@gmail.com wrote: Previous discussions of App Engine here have implied it to be associated with the APIs for Android, a phone OS.

Protocol Power - Pattern Matching Java Classes
I realized that supporting pattern matching on Java classes is pretty trivial - 15 lines code needed to be changed.

Re: Example of a real-world ClojureScript web application
You get Selenium running by using the clj-webdriver [1], thanks to Semperos for that one!

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. I don't have it at hand, right now, because I'm not at home, but I think the Google Closure book suggests using Selenium to automatically run the tests. Alternatively, using script/repljs might work. Do you have the tests running a browser window already? If so, I'd love to have a look at how you did that, because I haven't gotten that far yet myself. I'm going to give this another shot soon, because I've learned quite a lot about ClojureScript since I last tried to get testing to work. -fmw 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.
