RedBook draft out for OSGi applications and JPA 2.0 feature pack

I have the great pleasure to announce that the OSGi applications feature pack, which I have been working on for the past year and so, will soon have a dedicated IBM RedBooks publication to its name. The open draft can be found here.

JLine clojure wrapper

I recently wanted to write a bit of interactive shell and to my dismay discovered that apparently no one in the wide clojure community has yet wrapped up the JLine library. What a shame!

So I have knocked up something as best as I could. The result is available under on GitHub: http://github.com/tuor713/uwh-clojure-common.

Example usage:

	(use 'uwh.common.jline)
	(use '[clojure.contrib.io :only (file read-lines)])
	(def processor (atom identity))
	(defn nil-safe [f] #(if (nil? %) % (f %)))
	(defn add! [f] (swap! processor #(comp (nil-safe f) %)))
	(run
	(commands
	(transform [f :file]
	(doall (map (comp (nil-safe println) @processor)
	(read-lines (file f)))))
	(reset [] (reset! processor identity))
	(include [re :any]
	(add! #(if (.matches % (str ".*" re ".*"))
	% nil)))
	(exclude [re :any]
	(add! #(if (.matches % (str ".*" re ".*"))
	nil %)))
	(replace [re :any s :any]
	(add! #(.replaceAll % re s)))
	(exit [] (reset! *exit* true))))
