Non-tail recursion (Clojure way to hierarchies)
Hello Guys! Here is the task: Assume that we have function called `fetch-from-source`, which used to fetch vector of maps from the data source. I want to make iteration on every fetched row (element of vector) and ask `fetch-from-source` again to add 'children' key to that row. And so on, until given depth. So i want to use map function on collection from some function `expand- groups`, which will call the same function `expand-groups` on every collection element to assign children on it. Keep in mind, that the map function is not last in my function, because i have to append one more row to mapped collection. Currently i'm just calling function, but there is a danger of StackOverflow. I can't use recur, because it's not last statement. As i can understand recur is good to build long sequences, but in my case i'm building hierarchy. What do you think guys? Is there are clojure-rish way to solve that problem?

Re: ICFP 2009 / ICFP 2010
So, I'm done for this weekend. What I have (and put on the blog) * a binary parser * the vm (interpreted, maybe I can turn it into a compiled vm in the coming week? any ideas? macros? have to think about it) * a graphical visualizer * a controller "framework", allows you to solve the actual problems, starting from the simplest, the Hohmann transfer What's missing now is only the binary writer, which should be straightforward to do now, maybe I'll take care of that the next couple of days, maybe not. Way more interesting would be to get this thing fast, and I guess compiling the vm should boost performance significantly, and it sounds like an interesting problem, too: Here's my chance to really get into macros (I guess?). But there are certainly other ways to improve performance. Will see. Thanks guys for the input on my "getting the fn name" problem, that's good to know, and great that 1.2 will change it, too.

Re: ICFP 2009 / ICFP 2010
OK, I'm done for this weekend. Here's what I got:
* the binary reader
* the vm ("interpreted" for now - would like to make a "compiled" vm.
still have to think about it, I guess macros would help?)
* a graphical visualizer
* a controller framework to solve the actual problems
The code is surprisingly modular and readable (if I may say so myself,
I was surprised at least).
All that's missing now is a binary writer to be able to hand in the
solution. But that is pretty straightforward, so I'm not sure if I'll
bother to do it in the next couple of days.
Way more interesting would be to speed this thing up, and the vm is a
crucial part, the instruction processor is iterated over A LOT. So
maybe here's my chance to finally learn macros... Will see, I guess
there are other things that I could do in the vm code to boost
performance, but macros are one thing I haven't really gotten around
to, except for some small and boring ones. Any suggestions on the
issue "compiled vm"?
And thanks guys for the answers to my "get name of fn" problem! Also
good to know is that 1.2 will improve this.
Cheers
Eugen

Re: Clojure Enhancement Proposals or "wish list"
Thanks for comments.
In fact, I have some other thing to recommend.
I think that there should be some kind of clojure "standard library". I
don't see how to write any code if I have to have 2 different versions
depending on underlying virtual machine, JVM or CLR. There are 3 python
implementations (CPython, IronPython, Jython) which support python standard
libraries at the moment.
For example, I have looked at "REPL on socket" example. I have naively tried
to start it under ClojureCLR. Of course, it ended with exception because
there are references to java.net and java.io.
.NET is standard in company where I work so I have no way to promote clojure
which runs on JVM.
Also, there is additional benefit of such standard library. It isolates your
code from changes in java libraries. I am not java expert so I don't know
rate of change of java libraries at the moment, but I remember that there
are some deprecated libraries in the past. Deprecated features are still
present in .NET environment.
I would like to help on building of such library (libraries), but I don't
feel confident to propose design. I don't know if functional or OO way is
preferred by clojure users.
Also, I see that there is clojure.java.io library. I think clojure.io would
be more appropriate name.
And one comment for the end. I find syntax for map lookup little bit
uncommon. I find get function easier to understand in code. What you think?
Best wishes, Franis.

Why does clojure-http stores cookies in a ref instead of an atom
I'm a clojure newbie trying to understand when to use atoms versus refs. In clojure-http.resourcefully, if you use the with-cookies macro stores the cookies in a thread local ref. Why a ref and not an atom? My impression is that refs are for when you need to coordinate changes to more than one variable, or maybe if you need triggered validations.

noob questions - Hello world + learning
Hi everyone, I'm 100% new to LISP, 95% new to Java, and 90% new to programming in general. Where and how would you recommend learning Clojure? I'm planning on buying Programming Clojure, but until then what would you suggest? I got Netbeans working with Clojure and the default template is this: (comment Sample clojure source file ) (ns com.yourcompany.defpackage (:gen-class)) (defn -main ([greetee] (println (str "Hello " greetee "!"))) ([] (-main "world"))) It ran and printed "Hello world!". Can anyone explain to me in detail what each statement means. I'm particularly confused by: (comment Sample clojure source file ) I thought all comments began with ; ? I understand what println does and that's it.

After setting up the Leiningen builds and moving the source files into a more appropriate structure, I'm now fixing all of the errors and test failures. Right now, pretty much everything that was in the vendor/conjure directory will be in the conjure.jar. All of the scripts and a new initial Conjure generator script will be in the plugin.

Maybe I don't know exactly how it works, but I would like to define routes with something like Rails old "/:controller/:action/:id", but clout seemed to require something more like "/book/:id" where book would then be hard coded to the book controller and the action could be figured out from the request method. Though this is somewhat closer to how Rails works now, it isn't very useful for me. Am I missing something, or is that how you designed it? How would the Rails route: "/book/1/edit" work? Clout does look like an interesting project, and will probably use it to some extent if I can figure out how best to do it. -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re-binding special functions in a Namespace?
Hello, I would like to re-bind some functions from a namespace with a macro. The list of functions to rebind should be determined at macro-expansion-time, the functions to rebind are marked with a special metadata-entry. I implemented it in the this gist: http://gist.github.com/436786 Can someone with a deeper understanding of the var-internals take a look at my code and tell me if it's okay to do that like this? It looks a bit "hacky" for me...

Re: noob questions - Hello world + learning
I don't think that Structure and Interpretion of Computer Programs is a good first-book if you want to start lisp-programming (Especially Clojure). It's very detailed and gives much insights, but Clojure is way more practical than this book. If you want to start programming Clojure, I'd recommend "Pragmatic Programming Clojure" or "The Joy of Clojure" (Even when JoC isn't finished yet). To your original question: That's a hard piece of code to start with. I'd recommend firing up a repl and trying with this instead of this template you've mentioned.

I think you're missing something :)
Clout is a very low level library. It matches routes using a
Rails-like routing syntax, but it doesn't do anything more than that.
You can match routes like "/book/:id", but you can also match routes
like "/:controller/:action/:id".
user=> (use 'clout.core)
nil
user=> (route-matches "/:controller/:action/:id" "/book/edit/1")
{"id" "1", "action" "edit", "controller" "book"}
It uses strings instead of keywords, because that ties into Ring
parameters better. I may change this in future to keywords; I'm not
sure which is best at the moment.
In any case, you could write a Ring handler function something like this:
(defvar- main-route
(route-compile "/:controller/:action/:id"))
(defn conjure-handler [request]
(if-let [route-params (route-matches main-route request)]
(let [params (merge (request :params) route-params)
action (find-action (params "controller") (params "action"))
request (assoc request :params params)]
(run-action action request))
(page-not-found request)))
Using this scheme, you get similar behaviour to Rails, and it opens up
the possibility of custom routes.

Re: Re-binding special functions in a Namespace?
This was in the original branch of the clojure-couchdb-project. I
forked it and rewrote all functions to take an argument instead of
using *server*.
This annoyed me, because it was complicated to use multiple servers
with one codebase (binding is annoying in multi-thread-applications).

But your idea doesn't improve things, no? You hard-wire the server at macro expansion time. So using multiple servers doesn't work at all. At least not easily. I still prefer the double approach. Bind *server* or pass it as an argument. You can add even another level of indirection. Make *server* an atom and set it once a startup. Then you don't even need binding. For local required different server you can use binding for a bunch off functions, you don't control. Or pass in a server if do control the code.

Huh? I don't see why I wire server at macro expansion time. You can pass a variable and it'll be integrated in the emitted code.

can not install clojure-test-mode using elpa (package.el)
Hi Clojurians, This weekend, while off the grid, I discovered that mvn clojure:swank and M-x slime-connect no longer talk to eachother. When I got back, I looked in M-x package-list-packages to see that there had been updates to clojure-mode (1.7.2), clojure-test-mode (1.4), slime (20100404). (swank-clojure is still at 1.1.0 though 1.2.0 is tagged in git; is that bad?) I'm tearing my hair out trying to get this crap to install, and it's past my bed time, so I'm hoping that I'm missing something obvious. Maybe someone has a pointer for me. Installing clojure-mode seems to run without error.

And even if you are trying to install it redundantly, how *exactly* is it an error that it's already there. End result: clojure-test-mode doesn't get installed.

There are some bugs in package.el that I have fixed in my personal fork but have not yet made it upstream yet. Try clearing out .emacs.d/elpa and trying again with the version at http://GitHub.com/technomancy/package.el and it should work although you will get byte compilation warnings. Sorry for the hassle.

I swear I tried just that and it didn't work. I'll try again when I
have Conjure working again. It's currently all sorts of screwed up as

Would it help to try to manually install swank-clojure 1.2.0 do you think? (package.el only provides 1.1.0). I'm developing against clojure 1.2.0-SNAPSHOT, while swank-clojure 1.1.0 seems to use clojure 1.1.0. // ben -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: Colon (:) in comments?
It is also possible to use the clj-todo module for annotating your code with todo items. http://github.com/tgk/clj-todo http://clojars.org/clj-todo Thomas On Jun 13, 4:13 pm, j-g-faustus wrote: > Hi, > > I get an exception whenever I put a colon in a multiline comment: > > (comment > TODO: x y z > ) > => # > > Is this a Clojure bug?

Keyboard Input in Applets
Hi All, I've been able to figure out many Java things based on Sun's online documentation, and this is undoubtedly due to my not being a Java programmer, but for the life of me I can't figure out based on Java examples how to get my Clojure JApplets to respond to keyboard input. Does anyone have any ideas as to how to go about doing this? (set! *warn-on-reflection* true) (ns ... ... (:gen-class :extends javax.swing.JApplet ??? :implements java.awt.event.KeyListener)) ... (defn -init [#^JApplet applet] ??? addKeyListener ) (defn -paint [#^JApplet applet #^Graphics g] ... (.drawString #^String @message 60 40) ...) (defn -keyPressed [#^JApplet applet #^KeyEvent event] (let [key (. event getKeyCode)] (cond (= key (. KeyEvent VK_LEFT)) (dosync (ref-set message "left")) (= key (. KeyEvent VK_RIGHT)) (dosync (ref-set message "right")) (= key (. KeyEvent VK_UP))(dosync (ref-set message "up")) (= key (. KeyEvent VK_DOWN)) (dosync (ref-set message "down" (. applet repaint)) Thanks, Rob -- You received this message because you are subscribed to the Google Groups "Clojure" group.
