[ANN] clj-xpath 1.3.3

clj-xpath is a library that makes it easier to with XPath from Clojure. I've never announced this library before (or any for that matter). Someone recently sent me a pull request to fix an issue in the README (during the Conj) so I thought I'd announce it to solicit feedback. The Leiningen coord

Re: Some Friend documentation and regarding documentation in general

Thanks David for the extra doc. I have had a try with OpenID. Everything works kind of expected. I had a question about "302 redirection prior to authentication" that I posted on github. Another question is how to link the concept of roles with the openid credentials. IMHO the doc is really l

Re: Clojure : a good start for non-programmers?

I would go with the book "Simply Scheme, Introducing Computer Science" by Harvey and Wright. Install the Racket system on your computer, and have at it. http://racket-lang.org/ Once you come up to speed on Scheme, you will have no trouble with core Clojure. But if you venture in the the Java i

Clojure : a good start for non-programmers?

Hello Clojurists! I'm a person in middle age (you know, too old to rock'n'roll, to young to die) and would like to programm but starting with functional programming. Regarding this i have some questions: is clojure a good start to learn programming? which (prerfer free online) is a good tut to

How about trying: nrepl-jack-in This is working good here, at least from within a leiningen project. Regards, Greg On Saturday, September 15, 2012 2:39:36 AM UTC-4, sal wrote: > > Hi Everyone, > Trying to setup emacs 24.2 on mac osx clean setup, nothing else. > > clojure-mode 20120808..

Re: Found bug in contains? used with vectors.

You could try the function some. => (some #{3} [1 2 3]) 3 => (some #{3} [1 2 5]) nil This uses a set as a predicate function. Greg On Monday, September 3, 2012 7:03:07 AM UTC-4, Goldritter wrote: > > I use Clojure 1.4.0 and wanted to use 'contains?' on a vector and get > following results: > >

Re: using "lein repl" as the Emacs Inferior Lisp REPL as opposed to a custom script that does "java -jar clojure-1.4.0.jar"

Hello, I am also using Leiningen in Ubuntu, and I feel your pain. One thing I would suggest is to remove anything related to your tool chain which was installed by Ubuntu. (except maybe emacs 24.x). You clearly have Clojure installed via the usual Ubuntu Software Center or related mechanism. Unin

Looking for help with a deadlock issue

I encountered a deadlock on one of our production systems (one out of 3) last night. Looking at a thread dump of the JVM, there are several (over 200) threads that are all waiting on a java.util.concurrent.locks.ReentrantLock from Keyword.intern. I've put up the thread dump and information about
