Re: apply func
why inc can't take each element and incr it giving the result ... 2 3 4 5 thanks in advance apply works as if you were calling the function with the elements of the vector. In other words: (apply inc [1 2 3 4 5) ==is like saying=== (inc 1 2 3 4 5) Which is not what you want.

Re: apply func
On Sun Sep 25 06:38 2011, Vincent wrote: I cannot understand why this does'nt work (apply inc [1 2 3 4]) ; apply inc to each vector element From the documentation: clojure.core/apply ([f args* argseq]) Applies fn f to the argument list formed by prepending args to argseq. This means that apply invokes the function once with the collection expanded to become the arguments to the function. So, (apply inc [1 2 3 4]) essentially expands to (inc 1 2 3 4). However, inc only takes one argument at a time. What you want to do instead is invoke the function for each item in the vector. For this, there is map: clojure.core/map ([f coll] [f c1 c2] [f c1 c2 c3] [f c1 c2 c3 colls]) Returns a lazy sequence consisting of the result of applying f to the set of first items of each coll, followed by applying f to the set of second items in each coll, until any one of the colls is exhausted. Any remaining items in other colls are ignored. Function f should accept number-of-colls arguments. Using map, (map inc [1 2 3 4]) essentially becomes: '((inc 1) (inc 2) (inc 3) (inc 4)), except that it is lazy, meaning that none of the increments are actually invoked until you actually try to use them. If you really want a vector, you can use apply for that: user= (apply vector (map inc [1 2 3 4])) [2 3 4 5] This apply/map combination is common in Clojure and other functional languagues. while this works (apply println [1 2 3 4]) ;; takes each element and prints it This works because takes a variable number of arguments. You can compare how map and apply differ when using them with println: user= (apply println [1 2 3 4]) ; one invocation with all arguments 1 2 3 4 nil user= (map println [1 2 3 4]) ; an invocation for each argument (1 2 3 4 nil nil nil nil) why inc can't take each element and incr it giving the result ... 2 3 4 5 I hope my explanation helps.

Overtone 0.4.0 - Clojure 1.3 ready
Hi everyone, given that Clojure 1.3 has recently gone GOLD (http://www.youtube.com/watch?v=n0pvFulUd98) I thought we should celebrate with a new version of Overtone with full Clojure 1.3 support. Overtone 0.4.0 is now on Clojars and tagged on Github. https://github.com/overtone/overtone/tree/0.4.0 In addition, all of Overtone's direct dependencies: osc-clj, at-at, midi-clc, byte-spec and indirect dependencies (if you have a monome) serial-port, monome-serial and polynome have all been updated to support Clojure 1.3. Here's the changelog: ### New * Support for Clojure 1.3 * Provide more separation between 'public' and 'private' APIs by moving non-public aspects of overtone.sc into overtone.sc.machinery * Similarly pull out 'private' machinery from overtone.sc.server into overtone.sc.machinery.server - overtone.sc.server now contains only public fns. * Create new helpers namespace for useful 'public' fns. overtone.util is now meant for internal/private util fns. * Define and use default Overtone at-at pool * Remove server dependence on studio.rig. Use #'boot-rig to boot and wait for rig to complete its initialisation * Improve doc for sin-osc-fb ugen * Improve doc for node-free * Clean up implementation of cgen macro * Rename boot to boot-server * Rename quit to kill-server * Make osc-validator check for actual types not the 'fuzzy' types Clojure uses * Add information about resolving collider ugen fns to collider docstrings * Teach resolve-degree about sharps and flats * Stop users from attempting to receive osc messages from the server when it's not connected * Various ugen metadata fixes * Various docstring improvements ### Examples * Add piano piece - Gnossienne No. 1 by Erik Satie ### Helpers * Add some useful string manipulation fns * Add some file helper fns * Move splay-pan into helpers ns * Move sc-lang converter here ### REPL * Add odoc - Overtone version of doc which gives information about ugen colliders * Add super rudimentary (but still pretty fun) shell fns ls and grep * Make find-ug and find-ug-doc macros so you can pass unquoted symbols as args * Allow ugen searches to also match the ugen name in addition to its full doc string * Teach find-ug to print the full docstring of the match if only one is returned ### Deprecated * Support for vijual representation of node tree ### Bugfixes * Fix clear-ids in allocator * Don't explicitly free node id when freeing node as this is already handled by a callback * Fix resolve-gen-name * Fix cgen bug in arglist generation * Fix snare drum inst Sam --- http://sam.aaron.name -- You received this message because you are subscribed to the Google Groups Clojure group.

clojure.contrib.io, clojure.contrib.http.agent and clojure.contrib.http.connection for Clojure 1.3
Hi guys, not really sure if this is of any interest, since I am sure you have plans for all the contrib libraries. However I needed a version of clojure.contrib.io, clojure.contrib.http.agent and clojure.contrib.http.connection for a workshop that we are doing, and we really want to use 1.3, so I made version of these which work with 1.3. Basically all I did was add ^dynamic where needed. The results are pushed to github: https://github.com/stoyle/clojure.contrib.io To make it work with leiningen I installed the jars in a privately hosted maven proxy. I don't want to take any credit for the libraries, of course, but I did this the quickest way I could, for instance created a new git repo. Hope it is ok. If you have plans to migrate these libraries in any other way, I will gladly help. Cheers, Alf -- You received this message because you are subscribed to the Google Groups Clojure group.

I don't think it's trying to cast your zero to a function. Instead, here's what I think is going on: In this expression: ((nextInt dummy) 0) The inner expression gets evaluated to some integer. The end result is: (some int 0) And that is where an integer is trying to be invoked as a function. Ultimately, I am not sure that 'iterate' is really the function you want. If you want an infinite lazy sequence of random integers, you probably want something more like 'repeatedly': (let [rand (java.util.Random.) nextInt #(.nextInt rand)] (map print (repeatedly nextInt))) Note that this sequence, being infinite, will not terminate. If you only want to print the first five random numbers, you can do something like: (let [rand (java.util.Random.) nextInt #(.nextInt rand)] (map print (take 5 (repeatedly nextInt I hope this helps.

Is clojure-1.3.0 too serious, enterprisy, and Java-like for this sort of thing? I found no clue in the list of changes. This has to do with the primitive math support in Clojure 1.3. Every number is now a primitive unless otherwise mentioned. `(pow2 63)` is throwing an exception now because 63 is a primitive int. If you want `pow2` to work well on large numbers you will have to use the arbitrary precision math functions like +', -', *', /', etc. You can also take advantage of BigInteger contagion by switching the initial value of p to 1N instead of 1. Thus you can write your function in two ways - ;;; Use arbitrary precision add function. Will return BigInteger when needed. (defn pow2 [n] (loop [n n, p 1] (if (zero? n) p (recur (dec n) (+' p p) ; +' instead of + ;;; Utilize BigInteger contagion. Will always return BigInteger. (defn pow2 [n] (loop [n n, p 1N] ; this is different (if (zero? n) p (recur (dec n) (+ p p) I hope that helps.

In addition to Baishampayan's excellent answer, it might also be useful to point you to the relevant documentation.

Re: aquamacs, slime and clojure on OS X
I'm quite happy using emacs's Scheme support. But then, I've never experienced the luxury of swank and slime. The Scheme modes work a bit better (for Clojure) than the Lisp modes, because: 1) it highlights matching square and curly brackets, not just parentheses; and 2) after you do C-u M-x run-scheme / java -cp... to start inferior Scheme mode, you can restart it with just M-x run- scheme (within the same emacs session). So, until you man up, and build the great edifice of leiningen + ant + maven + ..., something I'll probably never get around to, you can make do with Scheme mode. Good enough for the '90s! Some people are happy with mini-IDE called clooj that's under developement. You can find that on github. ciao, George -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: aquamacs, slime and clojure on OS X
I have some trouble. I'm on OSX Lion, and have a few hours ago installed Aquamacs and SLIME from http://aquamacs.org/download.shtml. Then installed lein/swank/and clojure-mode, as Phil suggested. In order to make it work I had to remove the autodoc option, by commenting line 20 from /Library/Application Support/Aquamacs Emacs/SLIME/contrib/slime-fancy.el: ;(slime-autodoc-init) So by starting swank manually with lein swank (or swank-clojure) + M-x slime-connect I can now evaluate Clojure code in the REPL; instead when doing a clojure-jack-in I get the following error: (from *Messages* buffer) Starting swank server... error in process filter: progn: Invalid read syntax: ) error in process filter: Invalid read syntax: ) (last lines from *swank* buffer) (provide 'slime-repl) ;;; slime-repl.el ends here (run-hooks 'slime-load-hook) Any idea?

Re: beginner question
All persistent data structures are immutable, but not all immutable data structures are persistent. For example, imagine an immutable array that, unlike Clojure's vector data structure, implemented conj by copying the entire array into a new one with the original elements plus the new one. Immutable, but the performance characteristics are abysmal. As a more subtle example, imagine an immutable array that, unlike Clojure's vector data structure, let you update arbitrary elements, and did not copy the entire array, but created an imbalanced tree of vector indices that had their values updated. A lookup in this augmented data structure would require first looking through the imbalanced tree for the index, to see if it had been modified, and only if it failed to find it in the tree would it be looked up in the original array. Immutable, but not persistent in the sense that it maintains the performance characteristics of the original data structure -- the augmented/updated data structure has slow access times than the original.

clojure : collaborative learning ...
Hi guys : - We started the BioClojure project to learn about Clojure by applying it to some bioinformatics problems. -Its gone well, and we now know the basics of leiningan, java-interop, and basic map-oriented programming. -But of course, thats not enough --- we are now aspiring to reach that next level of Clojure zen -- using the really powerful features, like macros --- to engineer a real app. So Is anyone interested in learning about incanter, machine learning, parser combinators, and clojure ? We wanted to add a text file analysis module to BioClojure, and it would be a good learning experience for all of us.

Sample application as showcase of Clojure DSL / Metaprogramming?
Hello, I'm learning Clojure (work mainly with Java and Ruby), interested in it after reading Paul Graham and watched very interesting presentation about persistent data structures by Rich Hickey. So, one of the cornerstones of Paul Graham articles is - Lisp has no syntax, so You can create any syntax that suits You best, and because code is just a data it's very easy to do. You can model any concept - create DSL best suited for Your problem or model Object Oriented approach, Inheritance, and so on. But I believe, it's very hard to demonstrate this advantages on the simple samples. You has to do something real and complex to see advantages of this approach. So, maybe there's an interesting Open Source Project that uses this approach? With clean code that can be seen as showcase of such techniks, and You can dig in it and see all this in action by Yourself? It would be really interesting. Thanks. P.S. One more small question - as far as I know right now ClojureScript doesn't support eval and requires Java for compiling, any plans to support this in future? ClojureScript compiler written in ClojureScript / JavaScript without Java requirement? -- You received this message because you are subscribed to the Google Groups Clojure group.

You might find my article useful: http://pragprog.com/magazines/2011-07/growing-a-dsl-with-clojure (Errata: http://forums.pragprog.com/forums/134/topics/9318) You can then dig into the code of stevedore: https://github.com/pallet/stevedore It's basically building an interpreter, but all of the same concepts as building a DSL.
