Data Literals: How to handle read errors?
Hey there, I upgraded to JDK8 and wanted to start using the new java.time.* packages. I started by implementing reader functions to get rid of #inst like: #time/local-date [2014 4 13] #time/local-datetime [2014 4 13 14 23] While that works fine and as expected, one thing I ran into is confusing error messages. For example, from a REPL: user= (pr-str #time/local-datetime [2014 4 1 0 0 2 999]) DateTimeException Invalid value for NanoOfSecond (valid values 0 - 9): 1215752191 java.time.temporal.ValueRange.checkValidValue (ValueRange.java:311) RuntimeException Unmatched delimiter: ) clojure.lang.Util.runtimeException (Util.java:221) Or another one: user= (pr-str #time/local-date [2014 4 31]) DateTimeException Invalid date 'APRIL 31' java.time.LocalDate.create (LocalDate.java:431) RuntimeException Unmatched delimiter: ) clojure.lang.Util.runtimeException (Util.java:221) The first part is what I expected, however the Unmatched delimiter part is not what I expected. Is there any special exception I should be throwing in a reader function that read something that can never be correct? Also why do I need print-dup? Nothing serious, just curious if its a bug or an oversight on my part.

[ANN] Cadejo, A MIDI management tool for Overtone
Hi everyone, I have just released Cadejo, a MIDI management tool for Overtone. It forms an infrastructure which defines how MIDI devices communicate with Overtone instruments. The release also includes 4 full-featured instruments. 1) ALGO, an 8-operator FM synth 2) Alias, a subtractive synth with extensive modulation possibilities 3) MASA, an organ loosely based on the Hammond B3 4) Combo, a simpler organ primarily used for illustration. All instruments have program banks with a few pre-defined patches accessible by MIDI program change. MIDI program 127 generates random patch data. Cadejo supports all MIDI channel messages with the exception of polyphonic after-touch. Some of it's feature are: - Keyboard layering and split points - Tuning tables for alternate intonation. - Velocity, pressure and controller mapping functions. - Separate poly and monophonic response modes. - Program banks with the ability to execute arbitrary Clojure functions in response to MIDI program change events. An introductory video may be viewed at https://www.youtube.com/watch?v=GgXCAMs2EQY The project may be found on git hub at https://github.com/plewto/Cadejo/ Thanks -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: My experiments with concurrent programming
Hi Cecil, On Apr 12, 2014, at 3:18 PM, Cecil Westerhof cldwester...@gmail.com wrote: I just started playing with Clojure a few days ago, so I am a tabula rasa. I attached what I have until now. If it can be improved, I like to know it. I had a look at your code and it's not clear to me what you are trying to experiment with. Possibly benchmark using futures to run the do-sequential function concurrently. I'll assume that for the moment and make a couple of observations... You are using atoms to store two values (max-diff and max-factor) that are used and changed in main-function. Did you really intend to share these across all the calculations? The code you've provided will have concurrency errors as a result. You might consider writing this as something like (the *completely* untested and so only good as a sketch): (def max-diff (ref 0.0)) (def max-factor (ref 0.0)) (defn init [type] (give-message (format Start %s type)) (dosync (ref-set max-diff 0.0) (ref-set max-factor 0.0))) (defn main-function [i diff] (dosync (ensure max-diff) (ensure max-factor) (when ( diff @max-diff) (give-message (format Different for %12d (%e, %e) i diff (/ diff i))) (alter max-diff max diff) (when ( (/ diff i) @max-factor) (alter max-factor max (/ diff i) The 'ensures' are there because max-diff and max-factor aren't really independent and some interaction between concurrent threads in the outer when could lead to some strange situations (like testing for max-diff (or max-factor) then finding that some other thread ran and changed max-diff (or max-factor) out from under you. Your concurrency will likely be restricted to (some subset) of your cores since there's no IO in there (you're dumping the actual logging off to an agent). This isn't a bug, just mentioning it, but there's something to think about below. There's a problem in your calculation of diff... it's always 0.0 which means that there's nothing being done in main-function. I changed it to something arbitrary (and *completely* untested and so only good as a sketch): (let [v (int (Math/sqrt i)) diff (Math/abs (- (Math/pow v 2) i))] No idea if that's reasonable, but at least main-function does something now. With the hacked up calculation of diff, I was able to demonstrate the concurrency problem in main-function by simply running (the *completely* untested and so only good as a sketch): (defn main-function [i diff] (swap! iterations0 inc) (when ( diff @max-diff) (swap! iterations1 inc) #_(give-message (format Different for %12d (%e, %e) i diff (/ diff i))) (swap! max-diff max diff) (when ( (/ diff i) @max-factor) (swap! iterations2 inc) (swap! max-factor max (/ diff i) and printing the values of iterations* -- with your swap algorithm you get different values for iterations1 and sometimes iterations2 for successive run. If you didn't intend to share max-diff and max-factor, then you'd likely be better off if do-sequential passed local values into main-function, something like (the *completely* untested and so only good as a sketch): (defn main-function [[max-diff max-factor] i] (let [v (int (Math/sqrt i)) diff (Math/abs (- (Math/pow v 2) i))] (if ( diff max-diff) (do #_(give-message (format Different for %12d (%e, %e) i diff (/ diff i))) [(max max-diff diff) (max max-factor (/ diff i))]) [max-diff max-factor]))) (defn do-sequential [start stop step] (reduce main-function [0.0 0.0] (range start stop step))) You've decided to use futures for concurrency. Maybe that's the whole point, but if you're just trying to get a feel for concurrency in Clojure then there are some options. I find I directly use futures and promises, at most, rarely (I can't remember ever using them directly, maybe in the very early days of Clojure). What I find handy for this sort of thing is something like pmap, and if you really want this asynchronous then have a look at core.async. Anyway, with pmap (the *completely* untested and so only good as a sketch): (defn check-concurrent [number] (doall (pmap #(do-sequential % check-until number) (range 1 (inc number) The shutdown-agents call is likely not what you want, you don't need it. You're using agents for the logging. This gets the IO out of your code being tested, but there's still a lot of formatting work happening there (not much of a problem). But you don't know the impact of the agent thread pool on your benchmark. It's possible that it acts as a throttle. You can avoid this easily by not logging anything in main-function (I've commented it out in the example above). Benchmarking is tricky to do. It's a lot easier to use something like criterium, kind of like this (I added the *verbose* dynamic variable for fun to the *completely* untested and so only good as a sketch): (def ^:dynamic *verbose* true) (defn

Re: [ANN] iroh 0.1.9 - class reflection and exploration
It's short because i hate typing... And it's meant to be 'intuitive' so that clojure users would find it relatively straight forward to pick up. The only unintuitive bit would be the .% and .% for class information and class hierarchy. The thing is, when combined with the threading macro, all the functions are very powerful tools at the repl: (. 123 .%) get class hierarchy (. 123 .?) get all methods (. 123 (.? :name)) get method name (. 123 .toString (.? :name)) get method names of (.toString 123) Giveit a go! And if you have any suggestions for short names, please let me know.

Potential Intro clojure projects - libraries and ideas with wow factor
A handful of developers at the organisation I work at, want to encourage interest in Clojure with the aim of using it in production amongst the organisation's wider developer community (hundreds of developers). We ourselves are Clojure hobbyists. We wanted to do this through a basic project (with few moving parts), so I wanted to get feedback on a couple of aspects: 1. Examples of basic project ideas that would be compelling to fellow developers not familiar with Clojure (e.g. something useful that you can do easily with Clojure that's harder to do in more established languages such as Java) 2. Particular libraries that again had a wow factor towards an objective not easily achievable in more established languages (perhaps related to data analysis, visualisation, or taking advantage of the benefit of lazy evaluation in a novel way as examples). I realise these questions are somewhat open-ended, but just wanted to spark off some ideas for us through bouncing these questions off the google group's members.

[ANN] clj-cursor 0.0.1 - server-side cursor for clojure data structures (inspired by om)
Hi, https://github.com/rlewczuk/clj-cursor This is my attempt at (properly) managing application state. It is based on David Nolen's cursor concept implemented in the om library. Cursor allows storing whole application state in a single structure, yet still be able to swap underlying application state and allow application components receiving changes without hassle (think online reconfiguration etc.). Current implementation aims at solving server-side application state, it partially overlaps with what Stuart Sierra work (presentations and accompanying Component framework/convention) aims at. Note that this is highly experimental stuff worth around two evenings of thinking/coding. Currently it is dead simple wrapper for maps and vectors, in many respects incomplete (yet it's propably enough for me to test it on some real world application). I'm announcing this very early version in order to spark some discussion about this topic as I haven't been fully happy with existing solutions for application state management (albeit Stuart's work did push things forward quite a lot). So, any suggestions will be welcome - especially I'm looking for more usage scenarios (in addition to two scenarios I'm currently aware of: distributing config/state across application components and storing local caches of certain types of data (rather low rate of change, eg. dictionary data).

Re: newbie seq question
Hi François, Thank you. I have read through each of the articles you've indicated and will read in full the braveclojure book. I am playing the syntax-quotes and will explore the io/resource package.
