Re: clojure-scheme - Compiling Clojure to Scheme to C
Great work! Just a question, why Clojure->Scheme->C, instead of Clojure->Clozure? That way there would no be any C compiler dependency. -- Paulo On Mar 14, 10:08 pm, Nathan Sorenson wrote: > I've modified the output of the ClojureScript compiler to emit Scheme code. > At this point the core library is successfully compiled by Gambit Scheme.

Try Clojure instance with web based REPL interface.
Hi all, If you want to try couple of quick things without waiting for "lein repl" to fire up, or you are just curious about Clojure but have not managed to install it yet, point your browser at: http://noirmon.herokuapp.com/ringmon/monview.html You will get syntax coloured editor, ability to start/stop Clojure scripts, persistent concurrent sessions and a chat facility to communicate with other people whose sessions are active at the same time.

Creating map from string
Hi,
I would like to generate a hashmap from a string. The key portions of
the string will have some a prefix such as @ to define that they are
a key. So the following string
"@key1 this is a value @another-key and another value @test1 and
other value"
would get converted to.
{ :@key1 "this is a value", :@another-key "and another
value" , :@test1 "and other value"}
What's the best way to do this?
Thanks,
Jimmy

Re: Creating map from string
You could use a regexp to pick out the key and the value - something like
this:
(into {}
(map (fn [[_ x y]] [(keyword x) (clojure.string/trim y)])
(re-seq #"(@[^ ]*) *([^@]*)" s)))

I think `for' is cleaner than map + anonymous function:
(into {}
(for [[_ k v] (re-seq #"(@[^ ]*) *([^@]*)" s)]
[(keyword k) (clojure.string/trim v)]))

Re: The extensible reader
So to answer my own question, this is in 1.4.0.
Here is an example:
(binding [*data-readers* {'user/f (fn [x] (java.io.File. (first x)))}]
(read-string "#user/f [\"hello\"]"))
returns
#
On the best way to pass types around, though, I still think this is an open
question.
The problem is that, currently, the default print behavior of java objects
is an unreadable form like
#
I think there should be discussion about defaulting this to
#java.class.name [args*]
this form is still unreadable by default, but with tagged literals, allows
users to define custom reader behavior per class.
Either that or is there a way to alter the printing behavior of java
objects locally, instead of globally as when defining a print-method for
that type?

Clojure code optimizer
Hello, I am a third year student majoring in computer science and I am interested in the Clojure code optimizer project proposed for GSoC 2012. Could you please give more details (or examples) on the types of optimizations the optimizer should be able to do? Also, what is a tree shaker implementation? I was thinking that an optimizer could be implemented as a rule engine similar to Jess or CLIPS in which rules contains patterns which need to be replaced and the code to replace them with. For example one could write patterns for generic linear recursive functions that should be replaced with linear iterative functions. Similarly patterns can be written for functions which replicate the behavior of an already existing function (such as reverse, map, apply etc) and a rule to replace those functions with the predefined ones.

how to include external lib with :foreign-libs in ClojureScript One?
hi, I think I'm almost there but I can't figure out how to include an
external js lib in a cljs one project. What's the correct way to do it
when working in development mode?
I have a dependency on unicodetiles.js in project.clj:
:git-dependencies [
["https://github.com/tapio/unicodetiles.js.git";
"8a1922b4977685bc168de147efc2a9c72a958b08"]]
And I added that to the classpath (not sure if that's necessary):
:extra-classpath-dirs [
".lein-git-deps/unicodetiles.js/
unicodetiles"]
In the compiler options in config.clj I tried adding :foreign-libs
following
http://lukevanderhart.com/2011/09/30/using-javascript-and-clojurescript.html:
(def ^{:doc "Configuration for the sample application."}
config {
:foreign-libs [{:file "C:/george/work/great-mystery/.lein-
git-deps/unicodetiles.js/unicodetiles/unicodetiles.js" :provides
["ut.core"]}]
})
And from a view.cljs file tried to require the namespace:
(:require
[ut.core :as ut]))
Working in development mode I get the error:

Re: 3d modeling tools
AFAIK there's not much projects focussing on 3D in Clojure, but you can
take a look at processing (http://processing.org) and one of it's Clojure
wrappers. It's a great little language for 2D/3D visuals, and there's
plenty of swarm-like demos for it (http://openprocessing.org). For 3D
calculations, (verlet) physics and more there's the java library toxiclibs
(http://toxiclibs.org), whose author is currently porting/wrapping to
Clojure.
It's not really a cut-and-dried solution, but it's pretty flexible and has
a simple API unlike a lot of 3D projects which focus very narrowly on games
development.

beginner help with views in ClojureScript One?
hi, I'm starting to modify the One sample application and can't get
the hang of rendering a new view. I've tried looking at some forked
projects but am coming up short.
I created a basic template /templates/game.html:
<_within file="application.html">
My game goes here.
I edited /public/design.html to add a link:
Form
Greeting
Play the game
And now I can click on the link at http://localhost/design.html and
see the template.
To check if I can see this in Development mode, in one/sample/
view.cljs I changed the render method for :init,
(defmethod render :init [_]
(fx/my-initialize-views (:game snippets)))
And in one/sample/animation.cljs added:
(defn my-initialize-views
[game-html]
(let [content (xpath "//div[@id='content']")]
(destroy-children! content)
(set-html! content game-html)
))
And in one/sample/snippets.clj modified the macro snippets:
(defmacro snippets
"Expands to a map of HTML snippets which are extracted from the
design templates."
[]
{:form (snippet "form.html" [:div#form])
:greeting (snippet "greeting.html" [:div#greeting])
:game (snippet "game.html" [:div#game])})
However when I browse to Development the content div is empty -- the
html looks like:
Does anyone have some suggestions on how to display the game.html
template when first browsing to Development? Thanks.

understanding data structures, and other low-level stuff
Hi all, I am starting to learn Clojure after buying the book 7 Languages in 7 Weeks (really interesting read) and working through the examples there. But my background is PHP (and no Computer Science degree) so my understanding of data structures and in general, my understanding of low-level CS ideas, is pretty limited to say the least - PHP only has arrays (which I read are only 'ordered hash tables' in fact) and objects so I've never had to think hard about which data structures to use, nor how they actually work. So I guess I'm asking whether anyone can recommend some good primers on data structures, both as they relate to Clojure, but also how they work in the fundamentals - e.g. what exactly is the classic model of an 'array' and how does it work, etc. I have read the various performance commitments for the data-types in Clojure on the .org site but even things like Big O notation are still pretty new to me. I'm sure this stuff is pretty basic for many, but I don't know it and would like to! I'm not afraid of some heavy reading; I'd rather get a really deep and solid grasp of the fundamentals, then a quick surface-level solution. If I'm to develop as a programmer I feel like I need to get looking under the hood as it were, even though I can get by in PHP (for the most part anyway) without this kind of understanding.

Re: Which emacs packages?
I would advice to just to through the emacs tutorial *Emacs Tutorial Learn basic Emacs keystroke commands* link that appears when you start emacs. There are some starter kits around, such as https://github.com/bbatsov/emacs-prelude https://github.com/technomancy/emacs-starter-kit Another advice is to have patience. Emacs is something that I classify as hard fun. So you can enjoy yourself learning it, but it won't be an easy ride. It does pay off, because emacs has decades of being hammered to be a great text crafting environment. Good luck.

Re: understanding data structures, and other low-level stuff
Feel free to ask follow-up questions on the basics privately, since many Clojure programmers are probably already familiar with them, whereas follow-up questions on persistent data structures are very on-topic, since I would guess many people who have studied computer science and/or programming for a while may not be familiar with them. The classic model of an array is based upon the implementation of physical RAM in a computer: a physical RAM, at a high level and leaving out details of variations, is a device where you either give it a command READ and an address, and it returns an 8-bit byte stored at that location, or you give it a WRITE command, an address, and an 8-bit value, and it stores the 8-bit value at the location given by the address. A classic array is a one-dimensional structure indexed by an integer i, usually from 0 up to some maximum value N, and every item in the array stores an item of the same size and type, e.g. all 32-bit integers, or all pointers to some object elsewhere in the memory. If every item fits in exactly B bytes, and the first item of the array begins at address A in the memory, then item i will be at address A+B*i in the memory. In terms of performance, computers are designed to be able to access any address in their memory in the same amount of time, no matter what address it is stored at, so with a couple of instructions to calculate A+B*i, the computer can read or write any element of an array within a constant amount of time (constant meaning it doesn't get larger or smaller depending upon the size of the array -- it is always the same no matter the array's size). With other non-array data structures like trees, accessing an element takes longer as the data structure grows to contain more items. I don't recall if it covers persistent data structures like the ones most commonly used in Clojure, but Cormen, Leiserson, and Rivest's "Introduction to Algorithms" is used in many colleges as a text in courses on algorithms and data structures. There are probably other books that would be better as a "primer", and it does assume you are comfortable with at least algebra and a bit more math, but if you got through a chapter of it and understood even half of it, you'd have learned something worth knowing about the subject. http://www.amazon.com/Introduction-Algorithms-Includes-CD-Rom-Thomas/dp/0072970545/ref=sr_1_2?ie=UTF8&qid=1332128117&sr=8-2 There is a newer edition than the one I linked to, but an older used copy for $25.00 might be closer to what you want if you aren't sure yet.
