Re: Grabbing Rotten Tomatoes movie ratings in clojure
> Neat project, have you looked into using their web service API > (http://developer.rottentomatoes.com/) rather than scraping? Hi Yeah that is a good idea. The purpose of this project was that I was finding my feet with Clojure and wanted to do something that retrieved and parsed html pages. Extending it to use the developer API looks like a fun next step which I will probably do. Justin -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: Grabbing Rotten Tomatoes movie ratings in clojure
An update on this little side project to grab movie ratings from popular a movie website: I've add it to github and included the project file and updated the README https://github.com/justinhj/movieratings Also fixed it so it works with a recent change their page format.

Re: Grabbing Rotten Tomatoes movie ratings in clojure
Thanks for the feedback Stuart I'll check out Enliven. I'm currently writing an app using Compojure, Ring and Hiccup, so it would fit nicely with that too by the sound of it.

Re: Entity component system
Thanks for sharing. I've also spent some time building a Common Lisp game engine that uses a component architecture for the game objects. For example in pong the player's paddle is made up of a visual, physical and logical components. (defun make-pong-player(side human sprite-def control-type name) (let ((phys (make-instance '2d-physics :collide-type 'paddle :y *paddle-start-y* :width *paddle- width* :height *paddle-height*)) ; (anim (make-instance 'animated-sprite :sprite-def sprite-def ;:current-frame 'frame-1 :speed 5.0)) (visual (make-instance 'rectangle :w *paddle-width* :h *paddle-height*)) (pong (make-instance 'player-paddle-logic :control-type control-type :side side)) (obj (make-instance 'composite-object :name name))) (add-component obj phys) (add-component obj visual) ;(add-component obj anim) (add-component obj pong) obj)) The objects implement message handlers in order to operate. For example the game engine sends update and draw messages. Users can write their own message types with custom argument lists. I've put the project on google code http://code.google.com/p/lisp-game-engine/ Although the pong game works I wouldn't consider this a finished project by any means; it's more an experiment in game programming using CL and the REPL. It would require significant refactoring to make it work with Clojure since I use mutable state a lot, but would certainly be possible.

printf output from threads
What do people use for logging debug output from threads? Either native threads created with Thread. or implicit threads via agents or pmap etc? I tried passing *out* to my thread function and then binding it to *out* in the thread, and this works but then makes the threads execute one at a time, and I'm presuming that is because my use of *out* in the binding block is blocking for the other threads which use it.
