In the last few weeks, there’s been a fair amount of Clojure news and activity here in our study group. Here are some links to things we’ve been watching.
- A new language release. On December 17th, Rich “cut a new release” of the language. This should bring the offical release up to date enough for most people, although you’re still advised to check out the latest from Subversion, especially a few months go by without another official release
- Streams vs. sequences. A lively discussion about the right implementation(s) of laziness and the role of caching in Clojure’s sequences. There is a move afoot to add true streams to Clojure, although the ramifications of such an addition are uncertain.
- Compojure. Yes, Clojure has its own web framework now, and it looks pretty smart. Its syntax is inspired by Ruby’s Sinatra, it interfaces with Jetty, and it lets you write HTML in a vector-tree fashion that looks odd but probably saves the experienced user lots of keystrokes. Eric Levigne has written some posts about using Compojure to run a website.
- Paul’s article on
beanand Java interop. A nice tip on making it easier (and more Clojure-ish) to work with Java libraries.
- Luke’s Markov chain generator and Michael’s post about it. Luke wrote a cool program that generates an output text from the pieces of an input text and uses pattern analysis and probability to mimic the style of the input text. Your humble blogger responded with a post examining the workings of the program and suggesting ways to build on it. This could become a group project.
That isn’t everything that happened in Clojure lately, not by a long shot, so feel free to comment to ad your own observations. Also, consider joining our study group list (link in the column to the right) to contribute. You don’t have to be in DC or come to meetings–we’d love to hear from you.
