Re: Using JPPF in Clojure - Class Loading Issues
My first try to get JPPF to work from REPL is changing the ContextClassLoader to an implementation derived from clojure.lang.DynamicClassLoader which caches the class bytes on definition. That did not work so far. Sometimes (.setContextClassLoader (Thread/currentThread) cacheClassLoader) does not even seem to work - since (.getContextClassLoader (Thread/currentThread)) still returns a DynamicClassLoader afterwards. In case caching dynamically created classes will not be included in any future Clojure version, I want to be able to intercept class definition for the caching. The best scenario would be, if Clojure had a compiler option that creates class files for dynamically created classes like *compile-files* in Clojure's compiler does when using (compile 'my-ns). *compile-files* seems not usable for that case in REPL by simply binding it to true. -- You received this message because you are subscribed to the Google Groups Clojure group.

Google Summer of Code 2012 Application
Hi there, I've been a hobbyist Clojure developer for some time now, and a lurker in the community. I'm very interrested in participating to the Google Summer of Code on the Clojure team. Clojure is a language that i love, and i would love contributing to it.

Advice on style implementation
Hi all,
Please have a look at the following function (explained in the doc
string). I have a bunch of rows that I need to aggregate using
different functions per field. I also need to apply the aggregate to a
subset of the rows. Obviously this is just like SQL aggregation, hence
the interface I've specified.
However I'm left wondering whether my implementation could be improved.
Particularly I very often find myself doing
(apply hash-map (flatten (for [[k v] some-map] ...)))
so often in fact that I feel like I'm missing something.
Any pointers or advice on improving my style will be much appreciated!
(defn aggregate
Aggregate rows using the functions provided in select and after
filtering the rows by where.
E.g.
(aggregate [{:a 1 :b 2} {:a 3 :b 4} {:a 5 :b 6}] :select {:a +}
:where (fn [r] ( (:b r) 6))) -- {:a 4}
[rows {select :select where :where}]
(letfn [(selected? [col] (some #{col} (keys select)))
(agg [col] (get select col))]
(apply hash-map
(flatten
(for [[k vs] (apply merge-with vector (filter where
rows)) :when (selected? k)]
[k (apply (agg k) vs)])

Don't have a direct answer to your question, but what about
implementing aggregate like this -
(defn aggregate [rows {select :select where :where}]
(let [projection (apply merge-with vector (map #(select-keys %
(keys select)) (filter where rows)))]
(reduce (fn [agg [k v]] (assoc agg k (apply (select k) v))) {}
projection)))

Re: Google Summer of Code 2012 Application
Oh that's very interresting, so in some way you *are* also decoupling ClojureScript backend from it's parse and analysis components ! But doing so in a separate project, and in a more ambitious form than what i proposed in my application. Maybe there is a possibility of pairing the projects ? It would be nice to have David Nolen feedback about that. Anyway, i'm gonna spend some more time studying your CinC code, and i will probably get back to you with numerous questions :) If you have any comments or corrections that you'd think may be nice for the GSOC applications, i'd be very happy !

Hi again!
I've played around a little with Chris Grangers editor and changed it into

Possibility to add the example input and the corresponding expected

Pluggable ui-widgets (like the slider and colorpicker in Brets talk).

(predicate dispatch to determine what widget to choose? :)
Pluggable widgets for visualising data(structures) could also be
created.(Perhaps inline widgets? Although I think that most often
would be more annoying than helpful.)
Use kibit to highlight code that could be rewritten.
Visualising the call-stack (as Chris suggested)
Graphs of relations between namespaces.

[ANN] shady 0.1.0: JVM interop classes with less heartache
Hi all:
Shady is intended to be a collection of JVM interop facilities. Right
now it contains two useful pieces of functionality for producing iterop
classes: a version of `gen-class` supporting dynamic redefinition like
`deftype`; and a `defclass` macro providing a `deftype`-like interface
to that `gen-class`.
For example:
(ns example.defclass
(:use [shady.defclass :only [defclass]]))
(defclass Example [field1 field2]
:extend BaseClass
:constructors {[String String] [String]}
Example
(-init [arg1 arg2] [[arg1] [arg1 arg2]])
(newMethod ^String [^int param]
(str example: field1 : param : field2))
BaseClass
(override ^Long [^Class class] 10)
SomeInterface
(implementedMethod []
Types defaulting to Object, as you'd hope.))
The interface is cleaner (IMHO), and normalized with the other Clojure
type-definition facilities. The support for dynamic class redefinition
is clinically proven to produce 73% less heartache for interop
situations where you need full JVM classes. Be warned though, under the
hood `defclass` does still use the same class-generation code as
`gen-class`, with all that implies (performance, methods backed by
functions bound to vars in the implementing namespace, etc).
You can get the source from github:
https://github.com/llasram/shady
And the jar from Clojars:
[shady 0.1.0]
This is the first Clojure library I'm pushing for broader consumption,
so feedback is more than welcome.

Re: Google Summer of Code 2012 Application
Raph, rather than do an edit pass at this point, there are some larger problems with your proposal you need to take care of. :) In my opinion, your proposals are too informal, Hi, I'm Raphael As I'm not going to be choosing them, I can't guarantee this is the case, but judging from http://www.booki.cc/gsocstudentguide/proposal-examples/ these are intended to be more like a short formal paper (with abstract or synopsis to begin) than a resume (though your tone is probably too informal for most resumes too for what it's worth). Make sure you've addressed all the items here: http://www.booki.cc/gsocstudentguide/writing-a-proposal/ Specifically: You don't have your full contact information (understandable since this is on a public github, but be sure that you include it as Google requested in the end) Your biographical information is too spread out, confine it to a single section and be brief (but complete). You have some great skills listed, I'd pull them out to a separate section (LLVM experience, VMKit experience, experience using git, any of the things you've already done relevant to working with clojure) You don't have any deliverables or a proposed timeline, and you haven't outlined the _specific_ tasks you'd like to complete in 3 months. For instance, your clojurescript to lua compiler says what you propose to do, but it needs specific items describing the how. Related work: You should be able to find some existing projects that relate to the proposals you are looking at, list them separately, it shows you've done your homework Also make sure you've address all the items on the clojure specific requirements, here: http://dev.clojure.org/display/community/Google+Summer+of+Code+2012+Application+Questions (second paragraph) Specifically, you seem to be missing: - Are you comfortable working independently under a supervisor or mentor who is several thousand miles away, not to mention 12 time zones away? How will you work with your mentor to track your work? Have you worked in this style before? - If your native language is not English, are you comfortable working closely with a supervisor whose native language is English? What is your native language, as that may help us find a mentor who has the same native language? - Where do you live, and can we assign a mentor who is local to you so you can meet in a coffee shop for lunch? -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Google Summer of Code 2012 Application
Great, thank you very much, i'm gonna address those points right away ! The thing is, there are some keys choices about the proposals that i probably need to make for the final application, and that's what i hoped to discuss here. Although i'm quite late and it leaves little time to consider different options. For example, for the ClojureScript backend project, i have two very different backend alternatives, and i need to choose one if i want to make a serious timeline, so i wondered what would seem like the most realizable and interesting alternative.

Re: ClojureScript One in Eclipse
Note that the browser-connected REPL (at least, when run via one.sample.repl/go) hoists itself up on top of the REPL you start via Run Clojure Application, and assumes that it's in a console, and therefore doesn't play well with the ccw REPL, assumes the opposite. I assume this means the browser repl from cljs-template would not work from ccw either? (I tried it, and I get a continuous stream of EOF errors scrolling by.)

Re: ClojureScript allows fns to be called with too many arguments
I would probably say that in questions like this, it's best to do it the way Clojure on the JVM does it. ClojureScript is still pretty immature, so using it as a reference standard is going to be troublesome. This is the approach clojure-py is taking. Consider Clojure-jvm to be the reference spec, everything else that doesn't make sense is a bug. Timothy -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Compiling Libraries With :aot
An AOT generated lib mainly avoids compilation on the fly when your app starts up. We use AOT here to avoid deployment issues that could be found at application startup (missing component, bad fn signatures, ...) or if we call Clojure code from Java using gen-class. On some application containers (tomcat, weblogic, ...), AOT can simplify your life when configuring your app context, you may need to refer to some of your Clojure components but the container can only refer to compiled classes. On the fly compilation is not an option in this case. I would not use AOT in dev mode or if you do not deploy frequently especially if your project is not mission critical and the application container does not require it.

Here's all the reasons I know of for doing AOT-compilation: - The code produces JVM classes with `clojure.core/gen-class`, which only produces any results when compiling. - The code needs to expose a JVM class as an entry-point for a JVM framework which expects to find and instantiate a class through reflection. (Usually in tandem with the previous case.) - One wishes to build and distribute source-less JARs of only the compiled code. Any I'm missing?

Re: Compiling Libraries With :aot
I would add that you can look at the resulting jar file and you will see both the source code and the .class files in it. By default the source is present but you can ask leiningen to remove it from the target. If you need to keep your code private, that's an option.

We encourage everyone interested in Lisp to participate. The main theme of the 2012 European Lisp Conference is Interoperability: Systems, Libraries, Workflows. Lisp based and functional-languages based systems have grown a variety of solutions to become more and more integrated with the wider world of Information and Communication Technologies in current use. There are several dimensions to the scope of the solutions proposed, ranging from embedding of interpreters in C-based systems, to the development of abstractions levels that facilitate the expression of complex context dependent tasks, to the construction of exchange formats handling libraries, to the construction of theorem-provers for the Semantic Web. The European Lisp Symposium 2012 solicits the submission of papers with this specific theme in mind, alongside the more traditional tracks which have appeared in the past editions. Registration: Until April 15th the registration fee will be reduced. Use the form on www.european-lisp-symposium.org to register.

Re: Congomongo or monger ???
Marcus Lindner: But it might be intersting to see the opinions from more experienced people ;). Monger [1] has several things Congomongo does not (or did not last time I looked at it): * No integration of clj-time (transparent Joda Time types serialization) * No integration with clojure.data.json * No query DSL à la Korma * No recommended way of validating your data Which means more choices to make and boilerplate code to write on your part. For basic usage they are probably very similar. CongoMongo still supports Clojure 1.2 while Monger was created from the ground up for 1.3 and its dependencies such as Validateur [2] also require Clojure 1.3. So if you have reasons to use 1.2, CongoMongo is a safe bet. Full disclosure: I am the author of Monger. 1. https://github.com/michaelklishin/monger 2. https://github.com/michaelklishin/validateur MK -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Compiling Libraries With :aot
Agree, I still wonder about the downsides of AOT, comments ?

Re: Compiling Libraries With :aot
This email is not from me, did'nt type anything... I wonder if my email client is buggy... Listed as a downer for Scala: Functional programming can be difficult to understand for a Java developer - same can be said for Clojure, so I think it is a similarity but he presents it as a difference. Wow. All the more reason for a Java developer to mess with it then! After all, Java doesn't (in general) preclude using a functional style so that would imply many Java programmers are missing an important tool in their arsenal. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Clojure group.

cljsbuild and checkouts?
Can anyone confirm whether lein cljsbuild can support use of the checkouts directory? I have tried this with a simple test. The code compiles without error but the checkouts dependencies are not included. I know that you can jar the cljs files but it is good to be able to work without doing this for small edits. I currently use a modified version of cljs-watch that does this - but I would like to switch to a more standard build path If not supported I will add this as an enhancement request.

Re: cljsbuild and checkouts?
Correction - the code does not compile in simple mode and above because the checkouts do not appear to be found.

[ANN] Clojure Namespace Browser (clj-ns-browser 1.0.0)
I still remember the first time I was introduced to Smalltalk, when my colleague demonstrated the class-browser - it was one of those jaw-dropping moments: all that information at your finger-tips of a live- and living system… Guess nowadays it's more nostalgia than anything else, but in many ways that Smalltalk development environment is still a hard act to follow. Hopefully this Clojure Namespace Browser will get us one small step closer to our ultimate development environment (… although I'm sure that some of you emacs-gurus believe you're already there ;-) ). The graphical browser should give you easier access to the documentation strings of all the vars in your live clojure project, as well as the source code, and clojuredocs' examplescomments. You can get all that info from the repl, but hopefully this browser should make it easier to … browse, explore, and find stuff in Clojure's vast collection of libraries. The installation is dead-simple - just add: :dev-development [[clj-ns-browser 1.0.0]] to your project.clj file, start your repl, evaluate (use 'clj-ns-browser.sdoc), and then (sdoc), and your up and running with this namespace browser always one click or (sdoc…) away… Caveat… it all works well on my MacOSX, but I have seen some issues with Lubuntu and missing unloaded namespaces - also I haven't tested it on windoze or other OS-flavors. So you mileage may vary… The code and some more info with some screenshots are available at: https://github.com/franks42/clj-ns-browser Finally, kudos to Dave Ray and his Seesaw - fantastic tool and near real-time support on the mailing list. (this has essentially been a 2 week project after Clojure-Conj/West - an after the kids are asleep project - no experience with Swing… a testament of how good seesaw is as an abstraction tool…) Please let me know if it works for you, and suggestions and feedback are more than welcome.
