Re: clojure struct with java
I suspect this... Var struct = RT.var(clojure.core, struct,employee :diego 10 :coach 1000); isn't doing what you think it will. That will set the root binding of clojure.core/struct to the string you gave it. you probably want to get the var for the struct function, and then invoke it with the arguments to create an employee struct instance. -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Reactions to google dart?
For me the real meaning of this is that support for new features in closure library will stop in its actual form in the years to come. Only bugs will be corrected, no more. This is already the case in a sence I think, because before Dart, GWT was viewed as the new official way to make new web applications at google. Closure library is not where google put effort for new developpments. GWT somewhat failed on some aspects and now google is betting on Dart. For short term, this change nothing to us. In the long term we might have to choose between staying on a legacy library (closure library in JS form) or compile to Dart instead of JS. For raw clojure script code, this would not be very important. As the semantics could be preserved. But call to APIs might change quite a lot. New APIs under Dart might have really different behavior than actual closure library. Like in a sence GWT API is already totally different beast than closure library. Long term this might mean that instead of compilling to raw JS and having a dependancy on closure library, we might choose to compile to raw Dart and use new Dart APIs. In a sence to keep with the with the latest trend and benefits of latest features. This is not the only choice, as long as the closure compiler from google is working and there are not too many bugs in closure library, there is no real problem. As this is open source, nothing prevent us to fix things ourselves if needed... Maybe we are more interrested by the compiler itself and by the low level closure API providing access to all browser features (DOM...) than using cutting edge API that will not be idiomatic clojure anyway. If we want more idiomatic libraries, we will have to make them ourselves anyways. My 2 cents...

SICP sqrt function generates unexpected NullPointerException
Hi everyone, I've encountered an unexpected NullPointerException while translating some early SICP code into Clojure 1.3.0. In particular, I'm implementing the iterative sqrt procedure from section 1.1.7. Here's my code: (defn square [x] (* x x)) (defn abs [x] (cond ( x 0) (- x) :else x)) (defn average [x y] (/ (+ x y) 2)) (defn sqrt ([x] (sqrt 1.0 x)) ([guess x] (letfn [(good-enough? [guess] ( (abs (- (square guess) x)) 0.001)) (improve [guess] (average guess (/ x guess)))] (if (good-enough? guess) guess (recur (improve guess) x) Rather mysteriously, this works correctly for inputs less than roughly (square 2718.259...); anything larger throws a NullPointerException clojure.lang.Numbers.lt (Numbers.java:3693).

Re: newbie, installation problem
I don't know how to install CLOJURE on Windows but i have installed it on Ubuntu Should i have to learn Java first? You don't need to know Java, you just need to have it installed already. Have another look at the Clojure getting started wiki page that Phil linked [1]. Linked from that page are installation instructions and tutorials for Clooj and Leiningen.

Clojure is basically a functional language; mutability is limited to a few specific constructs precisely because idiomatic Clojure code is expected to be nearly all functional, with mutability used only as necessary. Performance might be one reason to use mutability (though see above); another might be that some framework you're using more-or-les requires it. For example, Java's Swing has you provide a callback function that is supposed to know how to draw your app's content. But Swing can't pass your current world state to your callback, so the callback needs to be able to access the world state in some other way. A global atom holding the world state is a pretty natural solution in that case. -- You received this message because you are subscribed to the Google Groups Clojure group.

Sum on a list of maps

I'm a Clojure newbie trying to the following simple task:
Given a list of maps of the followign format: ({Type A, Value
5} {Type B, Value 4} {Type A, Value 7.2} {Type
A, Value 25.4} {Type B, Value 2.982})
I want to compute a list of maps such that each type appears once in
the list and the value of the type is the sum of the values, so that
in the example it would be:
({Type, A, Value, 37.6} {Type, B, Value, 6.982})
Any ideas?

Re: Sum on a list of maps
The best i could think was:
(defn calc-types [coll]
(let [types (map (fn [m] {:type (get m Type) :value (Double/parseDouble
(get m Value))}) coll) ; convert keys to keywords and values to doubles
it1 (sort-by :type types) ; sort by type
a (atom (:type (first it1)))
it2 (partition-by (fn [m] (if (not= (:type m) @a) (do (reset! a
(:type m)) true) false)) it1)] ; partition by type
(map (fn [l] {:type (:type (first l)), :value (reduce + (map :value
l))}) it2))) ; map reduce
Hope it helps.
P.S: Try to use keywords and numbers instead of strings, the function will
be simpler

Re: Sum on a list of maps
Someone cleverer than me to post the built-in function that already
does exactly what you want, but here's one way:
(defn sum-by-type [in]
(- in
(group-by #(get % Type))
(map
(fn [[k vs]]
{Type k
Value (reduce
(fn [acc v] (+ acc (Double/parseDouble (get v Value

vs)}
All the strings don't help much.

Re: Sum on a list of maps
You could first turn the Values from String into Double like this:
(defn step1 [coll]
(map (fn [m]
(assoc m Value (Double/parseDouble (m Value
coll))
Next, you can use reduce to calculate the sum per Value:
(defn step2 [coll]
(reduce (fn [res m]
(let [k (m Type)
v (m Value)]
(assoc res k (+ v (get res k 0)
{}
coll))
This yields a map:
{B 6.982, A 37.594}
Finally, this map can be turned into the list that you want:
(defn step3 [m]
(map (fn [[k v]]
{Type k Value (format %.3f v)})
m))
The steps can be rolled into one function like this:
(defn der [coll]
(- coll
step1
step2
step3))

strings and why the values are also strings instead of numbers?
If the keys were keywords, you could just use :type instead of #(%
Type) or #(get % Type) which would make for cleaner code. Just a
thought.

Sample (simple!) game on rosettacode.org
Hi, if your're not aware of rosettacode.org, it is a very interesting wiki where people submit algorithms and short programs in different languages so than it is easy to compare how different languages approach the same problem. To start learning Clojure, I've tried to implement RCRPG, that is a very minimal dungeon exploring game. You can check the code on the wiki (http://rosettacode.org/wiki/RCRPG/Clojure) and I've also set up a git repository on https://github.com/pistacchio/rosettacode.clojure.rcrpg This is my very first approach to Clojure, so I'd love to see comments and corrections on my code by more expert coders. It's a wiki, so by contributing you'll help the rosettacode project and me! ^__^ Thanks. -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: ClojureScript: API documentation
Frank, Apologies, ClojureScript at the moment is designed with a bit of a bias towards people to who already know Clojure. This is unfortunate since there are many people who could use ClojureScript *today* who don't need or want to invest in Clojure on the JVM. Because of the bias some obvious things aren't there yet (remember this is a language that's about 4 months old). Perhaps including docstrings should be a compiler option which is enabled by default (not compiling in advanced mode). Perhaps it should also be the default when launching the Rhino based REPL. I think that including the full set of documentation functions from Clojure would be big usability win. Thanks for bringing it up, we'll try to work on it.

Re: Pipe function
I really liked this one too, though my first draft of it was more like (defn pipe [test f] (fn [value] (...))) I've since expanded and generalized it into three related functions you can see at https://github.com/flatland/useful/blob/develop/src/useful/fn.clj#L16 fix is basically your pipe, except it takes a series of test/f pairs, and to-fix is my original version, returning a function of x instead of computing on x immediately (this is handy as you can map (to-fix string? read-string) over a collection, for example). Given accepts only one clause and is shaped right for use in - thread chains, like: (- x inc (given even? / 2)) I would love to see something like one of these make it into Clojure proper, but given that I usually complain about clojure.core being too big, I would be perfectly happy to see it in some other namespace. In the meantime, take useful for a spin, and see if the enhanced versions of pipe are of any use to you. If nothing else, I recommend you change the argument order to your pipe function: (defn pipe [value test f]) is clearly the correct signature, since it means that (like fix) you can use it in update-in/ alter/swap!/- chains.

Re: [ClojureScript]: Breaking change coming WRT object property access syntax
Sorry I didn't copy my perspective over here from clojure-dev as someone who's been working as a JavaScript dev for the past 6 years - The proposed change is not optimal and I think it clashes with the realities of JavaScript interop. (.property foo) Currently gives us a notion of place, that means we can set it: (set! (.property foo) bar) This convention is quite common in many JavaScript APIs, for example pretty everything in the browser: (set! (.id foo) my-css-id)) (set! (.fillStyle ctxt) rgb(255, 150, 0)) Now compare to the proposed change: (set! (. foo :id) my-css-id)) (set! (. ctxt :fillStyle) rgb(255, 150, 0)) I don't see any win.
