Re: new Clojure Compiler...
first that dinamic languages are better for developers, but you loose some performance compared to typed languages.. and jvm was created with types in mind.. so right now clojure data structures are implemented in java and typed, when you get it in the clojure runtime its boxed already. theres some good approaches for dinamic languages like trace-jits(notably the new mozilla-javascript and luajit) .. but we are not there yet.. (JSR's was created as lazy sequences .. rsrs) for the immutability you could see you can see the performance gains when you use transients against the immutable data.. i guess it cant compare in with mutable data when you use it sequentially(thats why transients get in the game)... but when you add concurrency to that scenario.. things get better and simpler for us.. :) On Mon, May 17, 2010 at 2:08 AM, Rob Lachlan wrote: > > for the persistent data.. well all this "laziness" and dinamic types, and > on > > top of that immutability should not perform well in pure clojure > > Why? > > -- > You received this message because you are subscribed to the Google > Groups "Clojure" group. > To post to this group, send email to clojure@googlegroups.com > Note that posts from new members are moderated - please be patient with > your first post. > To unsubscribe from this group, send email to > clojure+unsubscr...@googlegroups.com > For more options, visit this group at > http://groups.google.com/group/clojure?hl=en > -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Re: ANN: try clojure
Pretty enough for you now, David? You can thank Lau Jensen for tons of help making it pretty. Since I didn't know Heinz had already decided to throw my stuff out to the world, I'll go ahead and point out my plans now, since it still isn't finished. Right now, I'm working on making it a bit of a Clojure resource for new people. I'm adding links and such, and learning more JQuery as I go along. The most important thing that I know you're all wondering about is the tutorial. There obviously has to be a tutorial. I for one, have never really cared for the tightly integrated REPL tutorials in which you have to type into the REPL to move along. I understand that the whole point is to get the users to use the REPL, but I think I can do that by making most of the tutorial useless without trying stuff out in the REPL. The tutorial will be below the REPL, and it will be click- through. It will be mostly based on examples that should be tried out in the REPL, like the other ones, but not so tightly integrated with the REPL that you have to type expressions to move along. This is just my point of view, and that's how I'll do this. If everybody thinks that TryHaskell-like integratedness with the REPL is important enough, Heinz/somebody else is welcome to do it themselves. Just see if you like my version when it's done before you do so. ;) I should have some new stuff ready in a couple of days, and I'll post back when I do. On May 16, 2:09 pm, "Heinz N.

Nice diatribe against actors by someone who's apparently never... actually... used... actors.

how do I clojurize this java ?
Hi,
I was wondering how to 'clojurize'

from the java code below,which is the from the open source twitter4j
java library ( http://twitter4j.org/en/index.html )
from the source, .getInstance(args[0], args[1]) is a "protected"
method of TwitterStreamFactory, :

Re: Clojure web app + js libraries - any suggestions?
If you are taking Saul's approach, you might also want to take a look at generating XHTML, since XML support in Clojure is so easy, and strict HTML is a little more limiting. And if you were looking at Raphael, take a second look at plain-ol' SVG. It's already very good in Opera, Chrome, FireFox, and Safari. Microsoft will finally support it in IE 9. Raphael does not use a standard data form, so you could be stuck with your Raphael code for a decade after it's no longer necessary. SVG is more capable (Raphael uses it when available), is a stable, mature standard, and is part of HTML 5. To get an understanding of SVG, go grab Inkscape, draw a simple picture, and look at the SVG file it creates. It's beautiful stuff. -- You received this message because you are subscribed to the Google Groups "Clojure" group.

That is, on the "generate-sources" phase, you generate .java files that stub out the classes you mean to create in Clojure. Javac comes along, sees the stubs, and can compile all the classes together. Then, once Javac has done its work, you run Clojure to replace the stubbed .class files with the real thing. Solves the "chicken-and- egg" problem quite nicely. The stubs would contain Javadoc, annotations, and generics (eventually...), allowing Java frameworks to easily consume classes compiled from Clojure. That is, it would work with the compile-time annotation processor from Java 5 and 6, and it would also work with Maven plugins, since they use Javadoc (in Maven 2, at least) for annotations. I had imagined that Maven plugins would just sort of fall out from having a good stub generator. Has anyone talked about doing something like this??? This is how the Groovy cross-compiler works, and how GMaven (the Groovy Maven plugin) performs cross compilation. Of course, it should be much easier to do with Clojure. With Groovy you have to worry about all the intricacies of ANTLR, but parsing in Clojure is dead simple. Theoretically you should just have to look for the correct function names and metadata and spit out Java source. -- You received this message because you are subscribed to the Google Groups "Clojure" group.

You might also want to look into rlwrap. For Ctrl+C: it does not exit the Repl, it shoots your process in the head. Use Ctrl+D (with JLine or on Unix) or Ctrl+Z Enter (on Windows) to indicate end of input and shut down the system gracefully.

I presume you've read about JLine at http://jline.sourceforge.net/ given your masked character comment? I guess it's up to what you think is important. In my case I use jline because it gives proper line editing functionality with (by default) emacs key bindings. For example, "ctrl-a, ctrl-k" kills a line. "ctrl-p" gives me the line I just wrote, etc. For me, being used to primarily sitting at the zsh command line,I would not be able to use the plain REPL without it or I'd go nuts ;) -- / Peter Schuller -- You received this message because you are subscribed to the Google Groups "Clojure" group.
