ANN: 3 August Incanter and Clojure talk by Ben Evans (LJC, JCP) in London
Fellow Clojurians, The London Clojure User Group in co-operation with the London Java Community are proud to announce a talk on Clojure and Incanter by Ben Evans on 3 August at Skillsmatter in London. The sign up is here: http://skillsmatter.com/event/java-jee/ljclcug-incanter-clojure-presentation This presentation covers the Clojure programming language and the Incanter system for statistical computing and will be presented by Ben Evans. Clojure is a Lisp dialect which runs on top of the JVM, and so our treatment is especially geared towards developers who are already proficient in the Java language and environment. Attendees will gain an understanding of: The pillars and fundamentals of Clojure Clojure's novel language features and its powerful programming model Introduction to Incanter Why Clojure is a good language for statistical computing Exploring datsets with Incanter Interfacing with Excel and graphing and charting libraries I'm sure afterwards we will be repairing to The Slaughtered Lamb to have a pint or two.

I updated the Confluence getting started page to address this last week: Clojure is unlike most language in that you don't generally install Clojure itself; it's just a library that's loaded into the JVM. You don't interact with it directly, you use a build tool and editor/IDE integration instead. * IDEs and Editors [...] * Build Tools [...] http://dev.clojure.org/display/doc/Getting+Started Would this have helped if you had found it? Using the jar file directly is really not very common or convenient which is why it's not well-documented, but people coming from other languages naturally assume that the first step is to "install Clojure". It's unfortunate that the Getting Started page on clojure.org is in such an embarrassing state of disarray, but according to Clojure Core they can't spare any resources to fix it at the present time. The community-editable pages are generally much more helpful, but they aren't as prominent or easy to find. -Phil -- You received this message because you are subscribed to the Google Groups "Clojure" group.

That would mean the docstrings need to provide more detail in the source code. Not sure how practical that is since the docstrings would substantially outweigh the code - maybe Clojure/core could comment? I'd recommend using the community-managed clojuredocs.org website since anyone can login and add / edit examples and notes etc. Not as convenient from the REPL, I agree, but I find I always have clojuredocs.org and clojureatlas.com open in tabs in my browser when I need more detail. -- Sean A Corfield -- (904) 302-SEAN An Architect's View -- http://corfield.org/ World Singles, LLC. -- http://worldsingles.com/ Railo Technologies, Inc. -- http://www.getrailo.com/ "Perfection is the enemy of the good." -- Gustave Flaubert, French realist novelist (1821-1880) -- You received this message because you are subscribed to the Google Groups "Clojure" group.

This issue applies to "all" JVM-based languages but I wouldn't go so far as to say you need to know _Java_, there's just a little bit of Java infrastructure knowledge required. It seems like we need some sort of Java Classpath 101 on the community wiki. Mind you, as Phil hints in his edit, using the raw Java libraries just isn't how folks really use Clojure - the problem is that's what clojure.org/getting_started says right now but we're hoping to see that changed after the "big news" on July 20th from Rich in NYC. If clojure.org/getting_started told folks to use Leiningen to get started, I suspect we'd stop worrying about Java classpaths completely :) -- Sean A Corfield -- (904) 302-SEAN An Architect's View -- http://corfield.org/ World Singles, LLC. -- http://worldsingles.com/ Railo Technologies, Inc. -- http://www.getrailo.com/ "Perfection is the enemy of the good." -- Gustave Flaubert, French realist novelist (1821-1880) -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Just curious, is your background Java or some similar C-style language? I ask because folks coming from that sort of background tend to want braces and parentheses on separate lines and fixed indentation whereas the Lisp crowd tend to want trailing braces and "natural" indentation, i.e., continuation lines are indented so elements line up: (somefn arg1 (f arg2)) If I got that right the (f... should line up with arg1 above it. It took me a while to get used to the "Clojure way" of code/data layout but now I tend to avoid commas and just go with the flow of how pprint or my IDE wants to format stuff and I like the concise consistency. Sorry that doesn't answer your question but I hope it helps explain why the default pprint output looks the way it does? -- Sean A Corfield -- (904) 302-SEAN An Architect's View -- http://corfield.org/ World Singles, LLC. -- http://worldsingles.com/ Railo Technologies, Inc. -- http://www.getrailo.com/ "Perfection is the enemy of the good." -- Gustave Flaubert, French realist novelist (1821-1880) -- You received this message because you are subscribed to the Google Groups "Clojure" group.

java.lang.IllegalArgumentException: More than one matching method found: submit - when "letting" an ExecutorService
Hi guys. Experimenting a bit with code from "The joy of Clojure", and
I ran into a little problem. Trying to run this in the REPL gives the
following error:
user=> (import [java.util.concurrent Executors])
java.util.concurrent.Executors
user=> (let [*pool* (Executors/newFixedThreadPool (+ 2
(.availableProcessors (Runtime/getRuntime]
(defn dothreads! [f & {thread-count :threads
exec-count :times
:or {thread-count 1 exec-count 1}}]
(dotimes [t thread-count]
(.submit *pool* #(dotimes [_ exec-count] (f))
java.lang.IllegalArgumentException: More than one matching method
found: submit (NO_SOURCE_FILE:7)
However if I define pool as a Var it seems to work fine:
user=> (import '(java.util.concurrent Executors))
java.util.concurrent.Executors
user=> (def *pool* (Executors/newFixedThreadPool
(+ 2 (.availableProcessors (Runtime/getRuntime)
#'user/*pool*
user=> (defn dothreads! [f & {thread-count :threads
exec-count :times
:or {thread-count 1 exec-count 1}}]
(dotimes [t thread-count]
(.submit *pool* #(dotimes [_ exec-count] (f)
#'user/dothreads!
(from
https://github.com/joyofclojure/book-source/blob/master/src/joy/mutation.clj)
ExecutorService has three submit methods, and two with one parameter,
a Runnable and a Callable. Since Clojure functions are both, I
understand the compiler error, but why does it work when *pool* is a
Var?
The "let" version works when I cast the function to Runnable or
Callable, just wondering why there is a difference.
Cheers,
Alf

Re: FleetDB or other "NoSQL" store for Clojure?
I’ve found the MongoDB integration to Clojure to be really good for most of what I wanted for my app. With the Congomongo driver, you very strongly tick off the first two points, but I don’t think it will go so well with your other constraints. Mongo explicitly excludes transactions (http://www.mongodb.org/display/DOCS/Developer+FAQ#DeveloperFAQ-HowdoIdotransactions%2Flocking%3F) and instead provides support for atomic updates on individual documents. If you can fit your data model for your transaction into a single document you may be okay. This seems to be a more common schema for NoSQL type DBs, where the documents themselves are quite large, rather than lots of smaller entries joined in many tables for a relational DB.

Re: Increasing indent level in pprint
The position of the braces might be a red herring here. I was mostly interested in figuring out how to increase the indentation level from 1 to something larger.

leiningen 1.6.1 not compatible with lein-nailgun 1.1.0
Hello, I've upgraded leiningen to 1.6.1, and found that I can't use it on my old projects. wei$ lein help Leiningen is a tool for working with Clojure projects. Several tasks are available: leiningen.classpath Problem loading: clean Remove compiled class files and jars from project. leiningen.compile Problem loading: Could not initialize class leiningen.deps__init leiningen.deploy Problem loading: leiningen.deps Problem loading: Could not initialize class leiningen.deps__init ... I tracked the issue down to lein-nailgun (I believe it requires some dependencies incompatible with the new version of lein), but I'm unsure how to fix it. A more general question: how do you find the latest version number of a library? Thanks, Wei -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Questions About Assoc-in, Dissoc-in, etc.
I've been using assoc-in and dissoc-in to navigate through nested associative structures (HTTP requests). Had some questions: 1. Why doesn't dissoc-in take multiple key-sequences? For example: (dissoc-in m [:a :b :c] [:a :b :d]) I can do this using a series of dissoc-in calls, but it might be easier to just have this naturally there. 2. Why isn't there a select-in? Even dissoc-in is in contrib instead of in core. Is there an easier way to do these things that I am missing? 3. Similar to #1, why doesn't assoc-in take a sequence of key-sequences and values? For example: (assoc-in m [:a :b :c] 1 [:a :b :d] 2) Again this is possible by doing a sequence of assoc-in calls. Now is the reason these are not provided to hint that this might not be the most efficient way to do this kind of surgery? -- You received this message because you are subscribed to the Google Groups "Clojure" group.

My point was that the "natural" Lisp/Clojure indentation is to match
the items above so for:
{:something
the natural indentation is 1 and for:
(foo a
the natural indentation is 5: '(', 'f', 'o', 'o', ' '.
Indentation is not some fixed quantity you can change - it's dependent
on the structure of the data/code and the length of the symbols.

Re: FleetDB or other "NoSQL" store for Clojure?
Hello - I'd like to throw in my vote for Redis. The only downside is that there is not an officially supported port on Windows. However, you may consider using a service such as Redis to Go (http://redistogo.com) and just accessing that as you need it.

Re: can't set up Clojure 1.2.1
Phil: You ask whether, if I had found it, the following web page would have helped: http://dev.clojure.org/display/doc/Getting+Started+with+Emacs The answer: Definitely yes. The page advises me to use for bringing up a Clojure REPL java -cp path/to/clojure.jar clojure.main whereas the page http://clojure.org/getting_started advises java -cp clojure.jar clojure.main I followed the latter advice blindly because I didn't know what "-cp" was doing. What I have now done is follow the Confluence advice for setting the value of the Aquamacs variable 'inferior-lisp-program, and so far things are working well. Some time soon I want to set up a Slime plus Swank Clojure plus Leiningen environment instead, but right now I prefer to spend the time I have for such things digging deeper into Clojure proper. By the way, I don't want to come across as unhappy with Clojure and Clojurians. Starting with the creation of the language itself, I very much appreciate what you guys have done and are doing, and I predict that that creation and the subsequent evolution of the language will ultimately go down as a major development in the history of computer science -- at least, for the very important areas of programming multi-processor systems and of experimental programming (so important, for example, for artificial intelligence research). --Larry On 7/16/11 10:10 AM, Phil Hagelberg wrote: On Fri, Jul 15, 2011 at 11:29 PM, Larry Travis wrote: Thanks, Sergey. The problem was indeed a classpath problem. The part of my ignorance about Java that seems to cause me the most trouble is my ignorance about Java classpaths. I think some Clojurians underestimate the difficulties involved in learning Clojure without knowing Java first. I updated the Confluence getting started page to address this last week: Clojure is unlike most language in that you don't generally install Clojure itself; it's just a library that's loaded into the JVM. You don't interact with it directly, you use a build tool and editor/IDE integration instead. * IDEs and Editors [...] * Build Tools [...] http://dev.clojure.org/display/doc/Getting+Started Would this have helped if you had found it? Using the jar file directly is really not very common or convenient which is why it's not well-documented, but people coming from other languages naturally assume that the first step is to "install Clojure". It's unfortunate that the Getting Started page on clojure.org is in such an embarrassing state of disarray, but according to Clojure Core they can't spare any resources to fix it at the present time. The community-editable pages are generally much more helpful, but they aren't as prominent or easy to find. -Phil -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: (doc more-examples)
Or an option for more extended doc when launching REPL for those who need the extra documentation more than performance during development, or maybe a searchable dictionary panel at the left hand side of REPL, ala some versions of Ruby's irb. Meanwhile, thanks for the pointer to the clojure quickref at clojuredocs.org. Good enough.
