Programming Clojure Beta 5 is Out

Programming Clojure Beta 5 is now available. What's new:

A new chapter, Clojure in the Wild, with information on

I have rewritten Section 1.1 "Clojure Coding Quick Start." All dependent libraries (Clojure, clojure-contrib, etc.) are now prebuilt and included with the sample code for the book. This should make it much easier for people to get started.

I have rewritten Section 2.6 "Metadata" to clearly explain the difference between user metadata and compiler metadata.

Clojure and clojure-contrib continue to evolve. To make sure you have the latest, greatest version of the sample code from the book, go and grab the github repo.

Thanks to everyone who has been offering feedback. I have cleared over 300 entries from the errata/suggestion page.  Keep the feedback coming!

Clojure Wins Again

Steve Yegge's most recent post takes a right angle turn about a third of the way through, and begins a comparison of Emacs Lisp and JavaScript.

And the winner is ... Clojure!

OK, Steve didn't say that. What he did do was call out things he liked about JavaScript and Emacs Lisp.

For JavaScript:

  • momentum
  • (namespace) encapsulation
  • delegation (polymorphism?)
  • properties (by Steve's definition)
  • serialize to source

For Emacs Lisp:

  • Macros
  • S-Expressions

I first picked up Clojure looking for many of the same things that Steve wants. I found them. Clojure can do all the things on both lists above. (Serialize to source isn't formal yet, but check the mailing list. And of course, you will have to judge "momentum" for yourself.)

The scary thing is that Clojure wins the language war before you even learn about its signature features. When I started exploring Clojure, I quickly realized it had everything I wanted, which could be summarized as "Lisp that really embraces the Java platform."

Then Clojure changed the definition of what I wanted. Now I also want

If you have half an hour, watch a compelling vision of what software development will look like in 2010.
