Hi everyone, I was perusing Amazon for some books on Clojure and Lisp and came across Let Over Lambda. From its reviews, it seems that this book may be useful for macro development in Clojure. Has anyone else read this book? Do you think it would be a good book for Clojure work? Thanks! -- Y

Re: Trouble with classpath

Thanks for the tips and the welcome. I have been wanting to learn clojure for over a year, but teaching has been keeping me busy! Summer is here and it's time to learn. It appears that restarting the repl fixed that issue. I then tested the same code in a terminal repl and the CCW repl and I ge

Hi everyone, I'm new to clojure and I have been working through Clojure in Action as well as Chas Emerick's webcast. I created my environment in Eclipse and CCW, but I am having trouble using "use" to get the json library in my program namespace. I have the leiningen project.clj use the [org.d

Yeah I don't like that either. Consider (comp vals (partial group-by identity)). On 2012-03-29 16:18 , "David Jagoe" wrote: >Hi all, >I'm sure I'm missing a really simple way of doing this! > >Given a sequence like this: [1 2 1 2 1 1 2 1 2 2 2] > >partition it to get this: [(1 2) (1 2) (1) (1 2)

I agree that title attribute is the way to go. You shouldn't use the alt attribute for tooltips though, as this violates accessibility standards. Alt should either contain a literal description of the image, or be left empty. On Mar 23, 2012 1:11 PM, "Cedric Greevey" wrote: > On Fri, Mar 23, 2012

GSoC: Browser-based Clojure(Script) editor

Hello! I am thinking of applying to GSoC and I found the proposal to continue working on Chris Grangers Clojure(script)-editor in "Bret Victor- style" really interesting. I have some ideas on features that I think would be nice to have, other than opening, saving and compiling files: Visualizatio
