Re: Regarding http://clojuredocs.org

[binita]

Yes , agree with puzzler . 
Also the Search feature at http://clojuredocs.org is awesome. Personally, 
as a newbie , I find it very helpful, to be able to search and see the 
examples.

I didn't find the same at http://clojure.org/documentation, 
http://clojure.github.io/clojure or at http://clojure-doc.org though.

Thanks

what does "defserverfn" mean?

[Waldstein Wang]

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.

Re: what does "defserverfn" mean?

[Chris Ford]

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.

Cheers,

Chris

Re: Regarding http://clojuredocs.org

[Stefan du Fresne]

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.

 Hi,

 I have a web service returning edn representations containing many 
 java.util.Date values. Using a profiler, one Hot Spot is inside the 
 clojure.instant/print-date function. The relevant reflections warnings are:

 Reflection warning, 
 instant.clj:172:20
  
 - reference to field get can't be resolved.
 Reflection warning, instant.clj:174:15 - call to format can't be 
 resolved.
 Reflection warning, instant.clj:174:5 - call to write can't be 
 resolved.

 Adding a ^ThreadLocal annotation to thread-local-utc-date-**format and 
 a ^java.text.DateFormat to utc-format resolves all reflection warnings.

 I tested the speedup with 

 (time (let [d (java.util.Date.)] (doseq [_ (range 10)] (pr-str 
 d

 which takes about 1500 ms without the type annotations and about 500 ms 
 with type annotations.

 A single web service access is speeded up from about 350 ms to 250 ms. 
 The response contains about 3000 java.util.Date values.

 I could create a pull request if that would help. But I like to discuss 
 the change first. I have no CA so I use Clojure instead of Clojure Dev.

[ANN] Two Essays

[Timothy Washington]

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  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 , which explores a good set of tools for
Web-Based and Rich Internet Applications.


Cheers

core.match on a set

[Phillip Lord]

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?

Phil

Indeed. You will find the defserverfn macro definition in

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.

Re: ANN Introducing Machine Head, a Clojure MQTT client

[Thomas]

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.

[ANN] Puny, a tiny layer for persisting Clojure maps into Redis hashes

[ronen]

Puny is a tiny layer for persisting Clojure maps into Redis hashes, it aims 
to reduce boilerplate and to enable end to end life cycle management of 
entities from validation to data migration and indexing.

It includes support for:

* Complete generated CRUD API.
* Automatic keys and id management (both generated and internal to the 
entity).
* Automatic Validation checks.
* Declaring indexes.
* Attaching persisted metadata like versioning etc..
* Defining interceptors on CRUD functions enabling support for security 
checks, automatic migration etc..

Puny is based on [carmin](https://github.com/ptaoussanis/carmine), a big 
thank you to Peter its author.

For more info please visit: https://github.com/narkisr/puny

Re: boolean java interopt puzzle/bug?!

[John D. Hume]

That behavior seems like a bug to me. Do you know whether there's some good
(or stated, good or bad) reason for it?

Re: Question about vector-of

[Mark Engelberg]

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?

Thanks,

Mark

Re: Question about vector-of

[David Nolen]

(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?

Clojure - Where to start?

[Anurag Ramdasan]

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.

http://clojure-doc.org can cover some of your needs, although it does not
cover monads.

Read source code of popular open source projects. There is certainly more
than one
"proper" way to program in a Lisp dialect ;)

JVM assertions in Clojure

[lopusz]

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!

Best regards,
Michal

Re: [ANN] Counterclockwise - Clojure plugin for Eclipse

[Mark C]

Nice update, I like auto-indent.

I ran into one small glitch on OSX, which is that the shortcut for toggling 
between unrestricted and strict/paredit mode wasn't working for me at first.
Going to Preferences -> General -> Keys : Switch Edit mode, and deleting 
then re-applying the Alt-D fixed it.  Just in case anyone else runs into 
that.

Re: Clojure - Where to start?

[Jeff Heon]

I remember reading a post with a list of open source projects with excellent 
clojure code.

Unfortunately, I can't find it anymore, but I remember Ring was on the list.

Re: clojars.org image for latest version of a project

[Adam Clements]

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! I find it ridiculously
useful not having to go to my browser to look up the latest version of
libraries I use all the time.

streams, reading bytes

[Brian Craft]

I'm struggling with how to gzip/gunzip byte arrays from clojure. I don't 
really get how clojure.java.io streams supposed to be used.

This appears to gzip a string:

(let [baos (java.io.ByteArrayOutputStream.)
  gzos (java.util.zip.GZIPOutputStream. baos)]
(.write gzos (.getBytes "foo"))
(.finish gzos)
(.toByteArray baos))


and I can expand on this to gunzip the string afterwards:

(let [baos (java.io.ByteArrayOutputStream.)
  gzos (java.util.zip.GZIPOutputStream. baos)]
  (.write gzos (.getBytes "foo"))
  (.finish gzos)
  (let [gzbytes (.toByteArray baos)
bais (java.io.ByteArrayInputStream. gzbytes)
gzis (java.util.zip.GZIPInputStream. bais)]
(slurp gzis)))

But slurp builds strings. I need to do this with byte arrays.  Do I have to 
rewrite slurp to build a byte array? Is there any simpler way to do this?

Zach Tellman's byte-streams library is very handy for these kinds of 
conversions:

Re: streams, reading bytes

[Brian Craft]

I like the blurb:

"This library is a Rosetta stone for all the byte representations Java has 
to offer, and gives you the freedom to forget all the APIs you never wanted 
to know in the first place."

My feelings, exactly. ;)

Thanks.

monger read reference

[Gary Zhao]

Hello

Anyone knows if I can set read reference in monger? e.g. "nearest". I 
didn't see it on their documentation.

Thanks
