Re: [Newbies] collection enumeration
cdrick a écrit : This can be fast if collection is an array and if you say 1 to: collection do: [:index | ... instead of creating an interval. The compiler cheats for to:do: on a SmallInteger and doesn't create the block. But I would only use this if the profiler showed it was a real improvement. Almost always I would use option C. same here or the method Bert has given.. #withIndexDo: It's strange that we have #withIndexDo: and #keysAndValuesDo: doing the same things on SequenceableCollection.

Re: [Newbies] Making cultural simulations in Squeak with Kedama
I tried using first the SqueakAtenex.image from the Extremadura project, because it's what my students and me used the last semester, but remaking the Epidemic example I found that there is a problem with the Kedama menu translation of Kedama in that image. In the english version you can see four options in the viewer of the Kedama Turtle: kedama turtle, scripts, kedama turtle breed and kedama turtle color. In the Atenex image you can see four also in that viewer, but one of them is repeated (kedama turtle) and kedama turtle breed is absent. It seems that kedama turtle breed was translated as tortuga kedama (kedama turtle), so adding a turtle is possible, but not increasing the amount of turtles in a breed (at lest not as is explained in the documentation). I think the Kedama in SqueakLand Squeak has been updated from the one in the Extramadura version, So I tried then the Squeak3.8-6665full.image but Kedama is not available from the object catalog. Trying to update from server says that no updates are available from server and using the Squeak Map I can`t find Kedama either. ¿How can I find/install the Kedama if its not available in the object catalog of an image? Kedama is, as much as I know, not available for 3.8. (maybe there is an old version somewhere). Then I tried Squeak3.9g-7054.image and Squeak3.9b-7051.image installed from squeakland directly (without using any deb repository for Ubuntu) and Kedama is there and I can reproduce the Epidemic simulation example, but anytime I tried to open a *.pr project I get some error messages about MessageNotUnderstood: SmallIntegerremoveKey:ifAbsent: and other one about fonts. I can made the pr files run (after getting a lot of that messages with the Abandon window), but some of them can't run in with the go button for example (I need to locate the proper scripts and make them ticking). In 3.9, we put some effort into merging all changes from squeakland and extramadura into the standard Squeak release. Sadly 3.9 brakes backwards compatibility for project loading (.pr files)... this is unfortunate, and I don't know if this will ever get fixed. A problem is a bit that both the squeakland and extramadura people did not join the 3.9 effort in any way, so all the eToy things are very likely not much tested.

RE: [Newbies] HTTPSocket class - getting to the instance
Hi Andy, Take a look at the method: HTTPSocket class httpGetDocument: url args: args accept: mimeType request: requestString Go about half way down after it has parsed the URL. Start at: HTTPSocket new. You too can get an instance of HTTPSocket but issuing new. Hope that helps! Happy coding.

Second. Due to my lack of knowledge I am now stuck ;-) I am still working on the problem of building a Smalltalk version of Wget. I have used the HTTPClient as my basic object and that is doing most of what I want. However, I can't get to the HTTP Headers. I noticed that HTTPSocket does seem to offer the headers but this is where I get stuck. The creation methods of HTTPSocket (i.e. telling it which url to go to) seem to only exist on the class side. But the methods for getting to headers etc only exist in the instance. I can't work out how to create an instance of the socket and tell it which url to go to. All the construction methods just seem to return the class. Obviously I am missing something pretty basic. Could someone please enlighten me?

The ugly details are found in HttpSocket's class side method;httpGetDocument: url args: args accept: mimeType request: requestStringIts a little ugly - an HttpRequest class should bundle up a lot of that complexity in a nice data structure that represents the structure of a request.But there it is.On Aug 24, 2006, at 8:58 AM, [EMAIL PROTECTED] wrote:First, Smalltalk is just amazing!
