Re: [ANN] Dunaj project, an alternative core API for Clojure
Dunaj, an alternative core API for Clojure, has been released! Try it yourself and check out its extensive documentation at http://www.dunaj.org/ Last Dunaj experiment aims to improve API's primary documentation. Official documentation is available at project's homepage at http://www.dunaj.org. API and SPI documentation is automatically generated from Dunaj sources. Other parts of the documentation are written in AsciiDoc format and are available in project's repository alongside other sources. Everything is released under the same license as Clojure. Library used for the actual documentation generation can be used to generate documentation for any Clojure project, and will be released soon. API documentation is presented in a clear and user friendly way. Vars in a given namespace are grouped by their purpose into several categories. In addition to Var's docstring, type signatures, examples and see also references are provided. Moreover, Dunaj defines new metadata keys for vars that provide additional information to IDEs. With these metadata, editors can offer improved and more precise highlighting and indentation. You can read about this and previous experiments at the documentation section of Dunaj at http://www.dunaj.org/doc.html Best, Jozef Wagner On Thursday, March 5, 2015 at 10:33:53 PM UTC+1, Jozef Wagner wrote: > > I'm happy to announce a project called Dunaj [1], which provides an > alternative core API for Clojure.

Re: Support for IBM JVM?
Created a ticket: http://dev.clojure.org/jira/browse/CLJ-1678 It appears there is no bug here. Some Clojure tests were written with particular constants that have equal .hashCode values, to test Clojure's code generation for case expressions when hashCode values collide. Somewhere between IBM JDK 1.6 and 1.7 the hashCode for the BigInteger value used in those tests changed.

Re: Support for IBM JVM?
You are welcome to file a jira ticket for this problem in the system and a patch would be welcome if it seems like an issue in the tests (assuming things that should not be assumed across JDKs). The percentage of users on IBM JDK is very small so it is not the highest priority platform, but I don't know of any reason that Clojure itself would have issues on it.

Re: [GSoC] Source meta information model proposal
Chris (and anyone else), Daniel mentioned to me in a note that it is ok for multiple students to submit a proposal for the same project. We do not know how many spots we will be given as an organization and whether particular students will meet whatever guidelines are set out by Google. So I think I was a bit incorrect in my understanding of the process and you would still be welcome to submit a proposal with the caveat that there are no guarantees that any particular proposal will move forward.

Re: Clojure Logo Licensing
Rich generally does not approve any use of the Clojure logo if: a) it's for commercial use (anything that involves collecting money) b) any modification or inclusion of the logo in other logos c) any use of the logo or "Clojure" where there could be confusion about whether something is "official" That's all pretty normal trademark usage stuff.

Sonian is hiring for remote Clojure positions!
For the official job opening, look here: http://sonian.com/about/careers/software-engineer-core/ -- there are a few other openings as well, have a look around! At Sonian, we work in Clojure full-time. We use it for just about everything, and wouldn't have it any other way. We're a fully remote team distributed across 5 time zones in the Americas. We pair a lot, talk all the time on IRC, and have lots of cool automations around our builds, tests, and github workflows. What do we do with Clojure? Tons of stuff! We work with Elasticsearch to index petabytes of documents in several clouds, including AWS and Softlayer. We use Datomic as a system of record to manage metadata over all those documents. We write RESTful, service-oriented platforms using tools like Pedestal, and components like Zookeeper and RabbitMQ. What would you do here? All the same kinds of things, working along with a great team of smart, experienced developers. We are a US-based company, so things like US eligibility, and a willingness to work around a timezone difference to accomodate that scheduling "center of gravity" are important to us. We love to pair on our code, so that kind of thing does matter. A couple of times a year, we get together as a team for meetups, where we can all get to know each other face to face too. We also attend conferences, especially showing up in force at Clojure/conj each year. Maybe you already know some of us!

Clojure Logo Licensing
Hello All, Please accept my apologies in advance if this is not the right channel to ask this question. I wanted to get some Clojure stickers printed for my upcoming Clojure(script) workshop at Mission Creek Tech Innovation Conference[1]. I see that the clojure-swag[2] has some stickers, but they don't seem close to the quality that sticker mule[3] delivers (sheets vs. shape cut stickers). I was just wondering if I can get the Clojure logo stickers printed through sticker mule and if there would be any potential legal issues if I do so. Any help would be greatly appreciated.

Re: Macro Help with Symbols and Evaluation
If there are a unknown number of layouts you can just define a map from
keywords to layouts: {:x_axis BoxLayout/x_axis ..}
Otherwise using java reflection is another option.
Thanks,

Re: Macro Help with Symbols and Evaluation
To provide a little more context, the problem I am trying to solve is this: Often in Java I see constructors that have a pattern of (ClassName. X) where X is some static integer value. For example, in Swing you build a Box like so (Box. BoxLayout/X_AXIS). I want to simplify this by doing something along the lines of (make-box :x_axis) by building the symbol and passing it into the constructor. Here is a complete example of how I've solved the problem using eval: (import '(javax.swing Box BoxLayout)) (defn make-symbol[sym] (->> x name .toUpperCase (str "BoxLayout/") symbol)) ;This works, but I am eval-ing. Seems like I could use a macro instead. (defn make-box[box-type] (Box. (eval (make-symbol box-type ;Works (make-box :x_axis) ;Works (map make-box [:x_axis :y_axis]) ;My first attempt using a macro (defmacro make-box-macro[box-type] `(Box. (make-symbol ~box-type))) ;ClassCastException - Symbol cannot be cast to java.lang.Number (make-box-macro :x_axis) ;Hmmm, works, but still using eval. Might as well use the defn. (defmacro make-box-macro2[box-type] `(let[x# (make-symbol ~box-type)] (Box. (eval x# (make-box-macro2 :x_axis) Hopefully one of you can point out some small change I need to make to make this work.

This is going to do two inefficient linear searches on every lookup.
There's a fix for that, but it meshes so well with the rest of your request
that I'll post it below.
But then one may want to replace .indexOf for some other ord-function- like

I'd suggest the following.
First, for explicitly supplying an ord-fn:
(defn order-by
"Given a map or function with integer values, returns a comparison fn
that will order the keys by these values.
That function will throw an exception if passed an argument that's not a
key in the map, or for which the
passed map or function throws an exception or returns a nonnumeric
value."
[order-map]
(fn [x y]
(- (order-map x) (order-map y
And then, for ordering by a sequence:
(defn order-by-seq
"Given a sequential coll of keys, returns a comparison fn that will order
the keys per the sequence."
[order-seq]
(-> (map vector order-seq (range))
(into {})
(order-by)))
(NOTE: untested.)
Note that the lookups inside the comparator are O(1) hashmap lookups now,
rather than linear .indexOf lookups. And this version *should* also work in
CLJS and Clojure-CLR since it avoids host-specific interop and only uses
clojure.core functions.

Problem deploying to heroku using the boot buildpack
When I try to deploy an application using boot I get:
-> Fetching custom git buildpack... done
-> BootClojure app detected
-> Installing OpenJDK 1.8...
/tmp/buildpack_8dd5d6e1eb90146982470bbee05eb89d/bin/compile: 192:
/tmp/buildpack_8dd5d6e1eb90146982470bbee05eb89d/bin/compile: Bad
substitution
cp: cannot stat '//opt/with_jmap': No such file or directory
Looking at the source code for the buildpack. It seems identical to how
the clojure buildpack works with leiningen. The problem occurs before
there is really any divergence in how the two work.
# Install JDKjavaVersion=$(detect_java_version ${BUILD_DIR})echo -n "->
Installing OpenJDK ${javaVersion}..."install_java ${BUILD_DIR}
${javaVersion}jdk_overlay ${BUILD_DIR}echo "done"
It doesn't get past the install_java
I deployed an app using clojure/leiningen, so I know the above could should
work.

Re: Sorting a collection of elements according to a given list of elements
I don't know if it is a more elegant implementation, but I found something
like this for maps in the useful library a while back, called ordering-map:
https://github.com/amalloy/useful/blob/master/src/flatland/useful/map.clj#L243-L245
I have been putting a few different varieties of sorted maps and sets,
including ordering-maps, into the Sets/Create and Maps/Create categories of
the Clojure cheat sheet here:

Sorting a collection of elements according to a given list of elements
Hi,
I want to sort a set/map according to an ordering given by a seq of
elements - e.g.
(def some-order [:u :a :e :i :o])
(def some-order-fn (order-fn some-order))
(sorted-set-by some-order-fn :a :e :i :o :u) ; --> #{:u :a :e :i :o}
This is what I came up with:
(defn order-fn [ks]
#(- (.indexOf ks %1)
(.indexOf ks %2)))
But then one may want to replace .indexOf for some other ord-function- like
this:
(defn order-fn
([ks] (order-fn ks #(.indexOf %1 %2)))
([ks ord-fn]
#(- (ord-fn ks %1)
(ord-fn ks %2
Now we may force the elements to be present in ks:
(defn order-fn
([ks] (order-fn ks #(.indexOf %1 %2)))
([ks ord-fn]
(letfn
[(-ord-fn [e]
(let [o (ord-fn ks e)]
(if (> o -1) o
(throw
(RuntimeException.
(format "'%s' not found in %s" e ks))]
#(compare (-ord-fn %1)
(-ord-fn %2)
Is there something like this in clojure.core already or a more elegant
implementation?

Re: [ANN] Dunaj project, an alternative core API for Clojure
Thank you for all the responses so far! 9th experiment is a small one compared to previous ones, but still worth of mention. Experiment #9 - Improved Math Facilities Dunaj extends available math facilities with means to specify precision of arithmetic operations and to round numbers. A pluggable mechanism for using random number generators is introduced, and math related API was extended with functions of an angle, exponentiations and logarithms. Instead of using prefixes and suffixes like in Clojure, facilities for unchecked and precise math are in Dunaj specified in separate namespaces. Common arithmetic functions are provided in dunaj.math namespace, with unchecked functions and arithmetic functions with arbitrary precisions defined in dunaj.math.unchecked and dunaj.math.precise respectively. List of available math functions is extended with exponentiation, logarithms functions and several miscellaneous ones. A separate namespace called dunaj.math.angle contains math functions of an angle, with floating point numbers. Precision of these functions is as implemented by host. Both circular and hyperbolic functions are available. You can read more about this experiment at http://www.dunaj.org Best, Jozef On Thursday, March 5, 2015 at 10:33:53 PM UTC+1, Jozef Wagner wrote: > > I'm happy to announce a project called Dunaj [1], which provides an > alternative core API for Clojure.
