Re: Overtone - Live @ Arnolfini

Hi Robert, thank-you for your kind words. Andrew Sorensen has been a huge influence for me, so it's really rather humbling for you to describe my efforts as being comparable to his. BTW, you should check out his latest project Extempore - it's pretty remarkable. Overtone doesn't really have di

Clojure contrib profiler error

Hi All I'm trying to run the clojure contrib profiler and I'm getting an error. Has anyone faced the same problem? user=> (use 'clojure.contrib.profile) nil user=> (defn my-function [x y] (let [sum (prof :addition (+ x y)) product (prof :multiplication (* x

Re: Clojure contrib profiler error

clojure.contrib is not supported in clojure versions 1.3+ The reason in this case is that in 1.3+, it is necessary to add ^:dynamic or ^{:dynamic true} in the def form (i.e. to the metadata) for the var to be dynamically changed with bindings. Fixed clojure.contrib.profile: https://gist.github.com

You are running clojure 1.3 or greater with the pre-1.3 contrib. Since 1.3, contrib has been split in separate libs, you can find where the different parts have moved here; http://dev.clojure.org/display/design/Where+Did+Clojure.Contrib+Go The profiling stuff did not make it it seems. A java pro

record constructor

My vague impression is this has been discussed somewhere, but I did not find a ticket in Jira when searching on "record, constructor", so I want to have some discussion here before considering entering a ticket myself. Often, when I create a record, I need to do some set-up more than just pass

Re: record constructor

for setting up objects as you say, I'm fine using (doto Object ... ... ...). Records, as everything else in Clojure promote immutability and so setting fields doesn't really make sense unless you're consuming external java classes in which case 'doto' suffices...at least that is the way I see

No worries... looking at the examples.clj in 0.4.1-SNAPSHOT, it is likely it won't even compile which is good evidence of how much your first email made me jump!!! If you want to run the examples just copy-paste the entire code in a namespace of your own while commenting out the travelling-s

Warren, I can't speak for others, but I can say that personally one of the reasons I love Clojure so much is that it doesn't try to be a OOP language, instead it cleanly separates data from logic.
