summing shorts vs summing ints
Hi all, Noticed in Clojure 1.3-Alpha8 that there is a large difference in speed when adding two Short/TYPE arrays rather than two Integer/TYPE java arrays. Is that something related to clojure, my code, or just a CPU-related thing when it comes to summing. I'd like to save some memory by using shorts, but for now that is too much of a speed sacrifice. Using criterium, the difference * adding int arrays: Execution time mean : 111.429525 us 95.0% CI: (111.426342 us, 111.432155 us) * adding short arrays: Execution time mean : 226.836034 ms 95.0% CI: (226.824310 ms, 226.846928 ms) (I saw no such difference in adding or multiplying floats vs doubles) Code: (defn plusS ^shorts [^shorts array ^shorts arr2] adds two Short arrays (amap array idx ret (short (+ (aget array idx) (aget arr2 idx) (defn plusI ^ints [^ints array ^ints arr2] adds two Int arrays.

Re: another question on macros defining functions
Ok, so what you really want is not to change how your program functions, but how your IDE/editor functions. That means what you really want is not a clojure macro, but an emacs macro--you want to extend the functionality of emacs to make your editing easier. The clojure code you write is not going to achieve what you want (though it may help you in learning how to write Emacs macros). I know enough about elisp to customize it so that it throws error messages every time I start it up, so I'll bow out here, but that's where you need to go from here. Cheers.

Re: summing shorts vs summing ints
I get reflection warnings on your `plusS` function. I think it's from adding the two `short`s. Remember that Clojure 1.3 only supports `long` and `double` primitives natively. The compiler may be a missing a case for conversion from `short` to `long`. If this is performance-critical code you're writing in pure Clojure, try using arrays of `long` instead. If you need to save memory by using `short`, try writing your array-adding method in Java. -Stuart Sierra clojure.com -- You received this message because you are subscribed to the Google Groups Clojure group.

[noob] porting an old project - where to begin?
I suppose the noob tag is appropriate ie I was around sometime last year and earlier but RLing got in the way of doing anything useful with this lovely language. Anyway, I've got this old project (https://github.com/doubleagent/ Magic--legacy- ) which I've recently gained a renewed interest in, and simultaneously am less concerned about the potential legal issues which made me disinterested enough to drop it 4 years ago. I'm proud that it still builds and runs, but don't take the readme too seriously, and I highly doubt the perl scripts work anymore. The intent was to write a program which assisted MTG (Magic: The Gathering) players by providing them with robust deck building tools and a way to compete over a network using the honor system. Several features are still unimplemented, and some were removed in this version because the java2d worked too poorly to accommodate them. I'd like to port it to Clojure, but in the process I'd also like to solve some fundamental problems. More specifically, real estate. In a real game you would not be able to see any of the cards in great detail, but get an overall view of the board, and be able to inspect cards more closely by zooming and panning (over the whole board - I find Wotc's way of zooming on individual cards undesirable). This is even more critical when there are a lot of cards on the field eg some decks can blast tokens onto the field which number into the hundreds. I'm unsure how to approach this core problem in Clojure. clj- processing looks interesting, but I would prefer something more high level b/c 3d graphics is difficult for me to wrap my head around.

Re: Best Installation Option
That was a weird guide. I don't see any real benefits from using some sort of 'installer' for clojure.

Re: Best Installation Option
I'm not a Windows user so I can't speak to any special needs in that environment but I'll +1 Leiningen as the simplest way I've found to get people up and running with Clojure. Clojure doesn't really need to be installed - it's just a JAR file that needs to be on your classpath - and Leiningen takes care of that very cleanly. I think the other thing to consider is your IDE. Depending on your background, you'll lean toward a Java-based IDE or Emacs to use Clojure. I use Eclipse and CCW (CounterClockWise) because my background has been Java-based technology for about 14 years and I like Eclipse. I'm able to work with Clojure, much the same way as I work with Java (albeit with much more productivity because of a REPL in my IDE).
