what does defserverfn mean?
Hi all, I am a newbie of Clojure and I am reading the source code of Twitter Storm, which has its major functions implemented by Clojure. I find following code: (defserverfn service-handler [conf inimbus] (.prepare inimbus conf (master-inimbus-dir conf)) (log-message Starting Nimbus with conf conf) But I did not find any related information of defserverfn in books or documents. Can anybody tell me why no books mention this keyword? Thx. -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: what does defserverfn mean?
Hi, Clojure allows the creation of macros, which means that developers can define new things that look like the keywords from other languages. For example, even defn is just a macro that builds on top of the underlying def and fn forms. I expect that the Twitter storm team have a macro called defserverfn defined somewhere in their codebase - don't expect to find it in Clojure documentation or books because it's not part of the core language.

Re: Regarding http://clojuredocs.org
Agree. I find the examples on clojuredocs really helpful (I find the official documentation often near-impenetrable), but it's super confusing how it references a bunch of old things.

[ANN] Two Essays
Hey All, I've been working on a few essays for a while now. But I wanted to release these two initial ones for public consumption (citations pending). All criticism and feedback is welcome. I'm eager to keep all of our tools and skill set at the cutting edge, and hope this can benefit developers and the community in general. *A)* Computation And The Mind http://bit.ly/1c4I6nG is only tangentially related to Clojure. I think though, that this is a good forum to get constructive criticism, as it addresses the mindsets needed when thinking about data, information, and the nature of computation. *B)* I do want to remain grounded though. So there's also A Developer's Toolbox http://bit.ly/154a6U0, which explores a good set of tools for Web-Based and Rich Internet Applications.

core.match on a set
I've been playing with core.match recently. One thing that I am confused
about is, I cannot match over a set (based on membership), unless I
convert into a map first.
So, for example
(defn map-set [set]
(into {}
(for [k set]
[k k])))
(let [x (map-set #{:a :b :c})]
(match
[x]
[{:a _ :b _}] 'match_a_b
:else nil))
returns 'match_a_b
Both of these...
(let [y #{:a :b :c}]
(match
[y]
[{:a _ :b _}] 'match_a_b
:else nil))
(let [z #{:a :b :c}]
(match
[z]
[#{:a :b}] 'match_a_b
:else nil))
returns nil. Am I missing something obvious?

Re: core.match on a set
There's currently no support for matching sets and I have no plans in the
near future. Patch welcome, it could be matched and optimized similarly to
map matching.

Hi Mike, You can use any of the brokers listed here: http://mqtt.org/wiki/doku.php/brokers Mosquitto is a free GPL (?) based broker which I have used in the past, I have used RSMB as well. And they all should work with Machine Head as it uses the Eclipse Paho Java client so I think it is very unlikely to be a problem.

Re: Question about vector-of
(a 1) will return a boxed value and (long (a 1)) will just cast it back to a primitive. There is currently no way to efficiently deal with the contents of gvecs. Their inclusion at this point is mostly about saving memory. In theory reducers could allow a primitive fn to do efficient work inside. As far as getting a particular element without boxing, I don't see a way to do that without implementing some interface like nthLong, nthDouble etc. Maybe invokeDynamic could help here in the future?

Re: Question about vector-of
(a 1) will return a boxed value and (long (a 1)) will just cast it back to a primitive. There is currently no way to efficiently deal with the contents of gvecs. Their inclusion at this point is mostly about saving memory. In theory reducers could allow a primitive fn to do efficient work inside. As far as getting a particular element without boxing, I don't see a way to do that without implementing some interface that supports nthLong, nthDouble etc. David On Thu, Oct 10, 2013 at 11:38 AM, Mark Engelberg mark.engelb...@gmail.comwrote: So do you just do: (inc (long (a 1))), i.e., manually converting to long primitive? Is there much overhead for that call, if it is already a primitive? To the best of my knowledge, you can't do: (let [^long x (a 1)] (inc x)) because I think primitive type hints only work in function headers. Is that correct?

Clojure - Where to start?
Hi, I have a good understanding on Common Lisp and I've worked on it a lot. I also have worked on Clojure a bit, very little actually, using emacs and nrepl. I am now looking for something intermediate level resources on Clojure. Mostly stuffs that deal with idiomatic clojures, clojure monads, lazy sequences etc. Can someone point me to such resources on the internet that could get me writing some proper clojure? I'd really appreciate that. Thanks, Anurag. -- -- You received this message because you are subscribed to the Google Groups Clojure group.

JVM assertions in Clojure
Dear All, Is it possible to use Java assertion system in Clojure? I want to put invariant checks in my code which can be turned on/off at runtime with java -ea/-da. http://docs.oracle.com/javase/7/docs/technotes/guides/language/assert.html The only mention touching this issue in Clojure I could find is https://groups.google.com/forum/#!topic/clojure-dev/kUCVUEALmWI it does not give any constructive suggestions, though. Has anybody used this JVM facility in Clojure code? Thanks in advance for any of your hints!

Re: clojars.org image for latest version of a project
Is there any chance we could get a route which simply returns this as plain text? I have an emacs plugin which looks up the latest version of an artifact on clojars (currently using some horrible regex) https://github.com/AdamClements/latest-clojure-libraries which would be much much nicer if it was using a supported api!
