Re: Improving visibility of clojure-doc.org
With the aim of increasing exposure, have you covered off boring SEO things like having a sitemap.xml and verifying the domain with Webmaster tools? I couldn't find a sitemap, but it does look like the content has been indexed by Google. On another note, I wonder whether it's worth clarifying the position of the site in relation to the other Clojure Documentations out there. I've often thought it's a shame to see http://clojuredocs.org/ fall out of regular updates. Having an up to date, searchable reference is one of the best things for a language to have. Is this likely to be rolled into clojure-doc in the future? Are they sister sites? If you want help bringing the http://clojuredocs.org/ site up to date I'd be happy to offer some time. I put together some Overtone docs based on a fork of it so I feel like I'm up to speed with the whole thing - you can see my fork here http://overtone-docs.herokuapp.com/ Thanks, On Wednesday, February 27, 2013 6:06:46 PM UTC, Michael Klishin wrote: Started in October 2012, http://clojure-doc.org is a pretty extensive community documentation effort. It covers Clojure, its ecosystem and tools and has two key goals: * We produce beginner-friendly content * It is dead easy to join and help Even though recently that hasn't been as much activity as in the past, it is not abandoned and continues to accumulate useful, beginner-friendly material. We constantly get praises from newcomers to Clojure who discover clojure-doc.org. Unfortunately, it does not appear even in top 10 in Google for clojure docs or clojure documentation and many community members are not aware of it. In part it is less visible because we no longer actively post progress reports. Things have settled down and most of changes now are small edits and improvements all over the place. It is a bit pointless to post progress reports more often than once a month or so. So I'd like to start a discussion about what can be done about it. The community (we have 40 contributors) has worked very hard on clojure-doc.org and I'd like to see high profile resources (namly clojure.org and leiningen.org) link to it. What would it take to convince clojure.org maintainers to do so? There are still guides left ot be written (macros, gen-class), but overall, I'd say there is no better source of freely available, beginner-friendly, hackable (no Clojure CA, everything is developed on GitHub [1], content is in Markdown) documentation. All it needs is some linking and promotion love. One way to help would be to start a campaign such as Mozilla's Promote JS [docs]. Unfortunately, unlike Mozilla key contributors behind clojure-doc.org largely lack graphic and Web design skills, so replicating that campaing is probably not an option. Do you have any ideas about how we can make clojure-doc.org more visible? Do you know who can help with getting a link from clojure.org? Do you think clojure-doc.org is not good enough to be the blessed open source documentation resource? Please post your suggestions and concerns. Improving CDS visibility will benefit the entire community plus all the people who will join it in the future. Most of the work is already done, it just needs to be promoted better.

Re: instance? with one argument
Yes, you are right about the lexical binding; I suspect that is less likely to hit people though. I don't know why I keep typing (instance? String) but I've done it a lot. Possibly because I am using a Java API with a lot of very similar classes; by the time I have managed to find out which class I need to check, I've forgotten what I was doing in the first place.

Re: what on earth is happening?
Just a general pointer: the bytecode verification that the JVM performs when loading a class has failed. There is a code path through the bytecode of the mentioned method such that it pops more than it pushes (Java bytecode is a stack-oriented machine language). So it makes sense that it blows up only when you try to actually run the code. Why it blows up---no idea. On Thursday, February 28, 2013 3:23:22 PM UTC+1, Jim foo.bar wrote: I've got a project 1.

Re: what on earth is happening?
I don't have the regular compile-and-load route in mind; this doesn't use concurrency. However if the runtime evaluation of a form results in just-in-time bytecode generation and classloading, I don't see why this couldn't be happening in any thread. Whether any of this could actually result in the errors you are getting, I don't know. On Thursday, February 28, 2013 4:25:59 PM UTC+1, Jim foo.bar wrote: WOW! Clojure compiles in parallel?

Clojure/West - don't miss it!
Clojure/West http://clojurewest.org, of course, is the Clojure conference taking place in sunny [1] Portland, OR from March 18-20th. Full schedule: http://clojurewest.org/schedule Registration: http://regonline.com/clojurewest2013 The night before the conference we've rented out Ground Kontrol, an excellent pinball and arcade mecca just a couple blocks from the hotel. We've got free play on all the games from 7-9 pm as well as early registration for the conference. (If your company is interested in sponsoring drinks at the event, please let me know!) I also want to mention that Relevance is providing full day ClojureScript training on the preconference day (http://clojurewest.org/training/). On the first day of the conference, we've got two tracks in the morning with talks on domain driven design, Cascalog, the data reader, REST, abstraction, and building a PaaS. In the afternoon we've got a talk from Stuart Sierra about building large systems with Clojure and some exciting work by Paul deGrandis on leveraging specifications as data. We also have two talks that will introduce the new Pedestal project from Relevance, which I think is going to be an important part of the Clojure ecosystem. And the day will end with a keynote from Rich Hickey - I don't what he's talking about yet but I'm betting it's something you'll want to hear. :) That evening, we'll have some more casual unsessions at the conference hotel. On the second day of the conference, we are two tracks all day long. Lots of ClojureScript talks about interop with JavaScript, asset pipelines, functional reactive programming, and ClojureScript in ClojureScript. We also have talks on DSLs, PuppetDB (written in Clojure), using Clojure to track deforestation, securing web apps with Friend, core.logic and SQL, macros, compiling Clojure to native code via scheme, and monitoring systems. To top all that off, we've got a 4 hour mini conference on logic programming that night - Byrd and Friedman will be closing the night but we've also got talks by David Nolen, Nada Amin, and more. On the last day of the conference, we're double-tracked in the morning with talks on concenative Clojure, macros and monads, working with mixed Clojure/ClojureScript code bases, editing with Emacs, debugging with Ritz, and managing your infrastructure with Clojure. After lunch we've got a bunch of great lightning talks lined up, Stuart Sierra talking about his new simulation testing framework Simulant, and a closing keynote from Matthew Flatt about metaprogramming in Racket. But hey, Racket's not Clojure! Exactly - the Clojure community has never been shy about learning and incorporating great ideas from other communities and there is much to learn about extensibility from their examples. Hopefully you can find some time to explore Portland a bit as well! It's a great city with amazing food, coffee, beer, book stores, and lots more. I think it's clear from the (incomplete!) list above that Clojure/West is going to be a tremendous learning opportunity for Clojure developers. I hope you can make it!

No I did not try Oracle Java6 and it would be a real hassle since it's not even installed...I think I've got openJDK 6 though...hmm I'll poke around with the dependencies of the namespace I'm trying to load see if that changes anything and if it doesn't I'll give openJDK a spin... Clojure seems rather sure it is my record definition...but if I try to load the namespace containing the record everything is fine...it is the 'consumer' namespace (workflows.clj) that doesn't load (sometimes)...

Did you try limiting the definition of the run protocol to the two arity case that you are actually implementing? funny you should mention that though cos I had 2 arities at first but now there is a library that defines a void 'execute' method that I need to hook on to so I added another 1-arg arity to cover that.

Re: what on earth is happening?
not that I have any serious arguments agaisnt what you're saying but this sounds very limiting...where is the power then? what are the chances that you will be able to extend a particular protocol to many types without needing at least 2-3 arities...it's perfectly fine that an exception will be thrown if someone calls the wrong arity isn't it? in addition, how about when extending a protocol to an interface that defines multiple arities? The concrete classes implementing that interface and thus your protocol, need to be able to be called with whichever arity is available. some other interface though may only defines a single arity but you still want to extend the protocol to - what do you do then? this is the first time I'm hearing about this and if you cold expand that would be great...If one hangs out on the list enough, it doesn't take much brains to realise that you are very knowledgeable and always have good insights/suggestions so I'm only trying to learn.

Re: what on earth is happening?
David has something here. I did not pay attention because they were commented in the snippet you posted. I remember playing around with this months ago and dropped it, unexpected and strange behaviours popped out and I did not have time to spend digging into it. We AOT all our code here and even that prove hard to stabilize with multiple arities. If some of your implementations are not in sync with the definition then it may explain the glitch. Certainly it can be hard to track what has been loaded first and what byte code comes up first. Luc P.

It's worth examining how protocols were done in ClojureScript. In every case where a protocol fn has multiple arities they are all implemented. The one outlier is IFn, and I don't personally have a good answer for that. in addition, how about when extending a protocol to an interface that defines multiple arities? The concrete classes implementing that interface and thus your protocol, need to be able to be called with whichever arity is available. some other interface though may only defines a single arity but you still want to extend the protocol to - what do you do then? Being able to extend protocols to interfaces is a nice JVM-centric convenience. It's not clear to me the whether the peculiarities around interface interop have much to do with the actual semantics of protocols. -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: ANN: lein-clr 0.2.0 for ClojureCLR
Hi Rainer, glad you're checking this out. This code (as I believe I mentioned above) requires a special build of the ClojureCLR compiler (see this github branch https://github.com/aaronc/clojure-clr - I just merged it with the clojure-clr master). I'm going to try to make some effort today to see if I can get Dave the patches so he can review them for inclusion in clojure-clr master. Hopefully soon we can have an official nuget package.

[ANN] Immutant 0.9.0 released
Hi all, We released Immutant 0.9.0 a few minutes ago, which features a much smaller distribution size, sharing caches with TorqueBox, a friendlier API for scheduling recurring jobs, and more stuff described here: http://bit.ly/immutant090 Toby and I will be at Clojure/West, I think doing an unsession, so please grab us if you want to chat about Immutant or whatever else. # What is Immutant? Immutant is an application server for Clojure. It's an integrated platform built on JBoss AS7 that aims to reduce the incidental complexity in real-world applications. It provides support for Ring handlers, asynchronous messaging, caching, scheduled jobs, XA transactions, clustering, and highly-available daemon services.

I actually spent some time a while back getting a very simple nleiningen working in ClojureCLR. I had nuget downloads working and also the ability to AOT compile namespaces and merge them into a single DLL. It's not fully ready for prime time yet though, in part because it depends on some custom modifications to the ClojureCLR compiler. In the long run, I'd like to work together on getting a full lein clr implementation working. I'd love to discuss further if you have time. By the way Dave - speaking of custom modifications to ClojureCLR, this past week, my colleague and I merged your latest master with our changes ( https://github.com/kocubinski/clojure-clr). I hope to put together some formal patches soon which clearly identify the changes I'm suggesting for the main compiler. While we're at it, a few other things I'm working on or have working in clojure-clr are: tools.logging and pinvoke (https://github.com/aaronc/ClojureClrEx) - logging is mostly ported but with only one backend working, pinvoke/dllimport works great, but no docs a nice interface to WPF (https://github.com/aaronc/ClojureWpf) - pretty stable, but again no docs yet nrepl (https://github.com/aaronc/tools.nrepl/tree/clr) - needs quite a bit more work Unfortunately, I haven't been too diligent with documentation, but I hope to correct that as time allows.

Clojure equivalents of .indexOf .lastIndexOf
Hi, I was looking at http://clojure.org/cheatsheet to find something I could use for getting an index of specific item in the string / vector. It looks like `.indexOf` / `.lastIndexOf (http://docs.oracle.com/javase/6/docs/api/java/lang/String.html#lastIndexOf%28java.lang.String%29)` are officially suggested options. I would prefer to avoid backend specific API like these (as I intend to compile to lua) and was wondering if it's reasonable to open issue requesting clojure native equivalents. I'd also be happy to provide patches to do it.

Adding string support to `split`
At the moment `split (http://clojuredocs.org/clojure_core/clojure.string/split)` only accepts regexps as delimiter argument. Is it reasonable to add support for string type delimiters ?

contains? for vectors
Hi,
Function contains?
(http://clojuredocs.org/clojure_core/clojure.core/contains_q) returns true if
key is present in the given collection, although arguably on some data
structures
one would expect behaviour to be different. In fact it's already different on
sets:
(contains? #{:a :b :c} :a) ; = true
Would that be reasonable to change behaviour for other types too like:
(contains? [:a :b :c] :a) ; = false
(contains? foo o) ; = false
(contains? '(1 2 3) 1) ; = false
So they do return `true` instead ?
If that will break too much code, maybe some other function can be added
instead ?
Regards

converting an xml database backup to insert statements
Preamble: I've read some about xml and clojure, and done some mostly trivial things (reading and writing values from and to xml). Most of the examples I've seen of parse, zip, etc are very elegant and do a great job at reading a specific x-path-like value or series of values. But I'm stuck trying to do what I think is a more involved operation with xml - to the point where I'm thinking clojure isn't the right tool. But I really enjoy programming in clojure, and so I'm hoping some folks on the list can help point me in the right direction. TIA! Detail: I have poked around some, read the APIs and examples, and I can even navigate using something like (- down down right node) but I can't seem to reconcile or mix that manual navigation of the zipper (that is passing locs to each fn) and what I think I really want from something like xml- (which doesn't return a loc, it returns a lazy-seq that's de-loc-ified). Overview: I have a backup of a database as xml. It's got a bunch of stuff in it, some of which I want and some that I want to discard. But I mostly have a blacklist of this is what I need to discard and I want everything else. Once I have the parts of the db backup I want, I need to translate them to insert statements to build the database back up. I'm having some difficulty wrapping my head around what I haven't even gotten to solving yet - that I need the list of tags and the value back, when something really nifty like xml- seems to be designed to only give me the values. Code (ish): Sample files below (or gisted https://gist.github.com/pbuckley/5060575). xml: config xmlns=some-url FAKENAME xmlns=another-url SomeSettings SpecificSettings FooVAL1/Foo BarVAL3/Bar /SpecificSettings /SomeSettings DoNotWant SomeEnormousChildren /SomEnormousChildren /DoNotWant MoreConfig Baz20/Baz Buz300/Buz /MoreConfig /FAKENAME /config And this non-working somewhat pseudo-code (it gets more pseudo the further you get): (ns config-backup.confdbackup (:require [clojure.xml :as xml] ; I think I need both zip and data.zip? [clojure.zip :as zip] ; different from clojure.data.zip? [clojure.data.zip :as zf] ; used to be zip-filter? [clojure.data.zip.xml :as zx])) (def my-xml (xml/parse my-db-backup.xml)) (def my-zipped-xml (zip/xml-zip my-xml)) (def this-worked (zx/xml- my-zipped-xml :FAKENAME :SomeSettings :SpecificSettings :Foo zx/text)) (def with-junk-removed (zip/remove (zx/xml- my-zipped-xml :FAKENAME :DoNotWant))) ; does not work (defn transmogrifier given the xml, nodes and text, create insert statements for them [things] (do-some-magic)) (transmogrifier with-junk-removed) ; returns insert FAKENAME SomeSettings SpecificSettings Foo VAL1 and the stuff from MoreConfig etc -- The king’s heart is like a stream of water directed by the Lord; He guides it wherever He pleases. -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Hi,
Function
contains?http://clojuredocs.org/clojure_core/clojure.core/contains_q
returns
true if key is present in the given collection, although arguably on some
data structures
one would expect behaviour to be different. In fact it's already
different on sets:
(contains? #{:a :b :c} :a) ; = true
Would that be reasonable to change behaviour for other types too like:
(contains? [:a :b :c] :a) ; = false
(contains? foo o) ; = false
(contains? '(1 2 3) 1) ; = false
So they do return `true` instead ?
If that will break too much code, maybe some other function can be added
instead ?

Re: contains? for vectors
This is a sore spot that has been discussed many times on this list[1]. The short version is that many people agree that the name contains? is misleading to newcomers, but according to Rich it's not changing any time soon[2]. What you want for linear searches is 'some (as mentioned in the doc for 'contains?). Also, why are you quoting your vectors (e.g. '[:a :b :c] instead of just [:a :b :c])?

Re: Clojure Performance For Expensive Algorithms
I didn't know reduce could be short circuited! I assume from the code below this is done calling the function reduced? Is this in Clojure 1.5 only and is where is this documented?

Re: contains? for vectors
Thanks Michael, This links are helpful. As far as I can see nothing like contains-val? or seq-contains? has being added though :( I'm trying to use cljs for performance sensitive code and high order functions like `some` don't really do it, while indexOf on strings in JS are well optimised by engines. Maybe something else can be considered like `includes?` to do that instead ? Also Rich says no better name was suggest for includes?, I think `has?` would have being a lot better name. Don't know if it makes sense to reply to that post at this point.

Re: Clojure equivalents of .indexOf .lastIndexOf
Although the cheat sheet is hosted on clojure.org, I'd hesitate a bit in inferring from its contents that .indexOf and .lastIndexOf are officially suggested options. More precise would be to say that when I was updating the cheatsheet a year ago to add many things that weren't already on there, it occurred to me that those would be useful for people to know about, even though they could of course write equivalents for themselves. I'm certainly open to suggestions for those entries on the cheat sheet if there is something better to suggest. (or any of it at all, really) If there already are Clojure core or contrib functions that have the same behavior and performance as .indexOf / .lastIndexOf, I'm all ears.

Re: ANN: lein-clr 0.2.0 for ClojureCLR
Rainer, I've pushed some updates to nleiningen. Be sure you do a git submodule update first. There is now a Bootstrap project that you can build from VS 2010 - enable Nuget package restore on it first and then try building. There is a private nuget package for Clojure.dll that it pulls. Then you use script\repl.bat to start a repl (you must do this from the root of the nleiningen dir). You should be again to compile nlein.exe using the following commands: user= (use 'nleiningen.core) user= (main compile) Let me know if you get this to work or if you have any problems. Please keep in mind that this is just a proof of concept really - the code is not too well organized yet. -- -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: In order to get java-like performance, one needs to write java-like code first?
Performance at doing what? why? what are your requirements and what is important to you? Your question is simple but can generate extensive debate. Don't expect a yes/no answer. See this extensive discussion and examples: https://groups.google.com/d/topic/clojure/byHO-9t6X4U/discussion it's funny how the phrase java-like performance is now used as a moniker for fast. when Java came out the phrase was c-like performance. when C came out, probably assembler-like ..its even faster if you build it in hardware too... just maybe not flexible in the way you would like.
