Re: [Newbies] Error: No content to install
Hi! I can invoke the image without problem. When I try to pass a script file on the command line there's a Error: No content to install. The script file 'file:test.sq' is set in the url field of HTTPDownloadRequest I guess you did not use a proper file URL? They generally look like: file://$HOME/startup.st regards, Göran PS. This is a common gotcha, IMHO we might add a default fallback looking in PWD for a file name if the arg does not look like a proper URL. ___ Beginners mailing list [EMAIL PROTECTED] http://lists.squeakfoundation.org/mailman/listinfo/beginners

[Newbies] Re: Adding methods to Integers...
Hi Patrick, some of the symptoms you describe have to do with a small set of classes being hardwired in Squeak's virtual machine. To see which they are, evaluate (printIt) Smalltalk specialObjectsArray select: [:each | each isBehavior] So when you do primitive arithmethic with your own subclass of LargePositiveInteger, the VM returns an instance of LargePositiveInteger (and not your subinstance of it). Of course the specialObjectsArray can be changed and from then on the VM (after being notified) will use your subclass but, I think this is not what you really want ;-) Putting your methods into Integer is fine as long as they do not conflict with anything else. Yes, this is the usual approach for adding new behavior to all the integers :) /Klaus On Thu, 12 Apr 2007 17:28:01 +0200, you wrote: Background: :: The most recent MathFactor Podcast ( http://mathfactor.uark.edu/ ) ended with a request to write a computer program that could, in principal, given enough time and memory, compute Graham's Number ( http://mathworld.wolfram.com/GrahamsNumber.html ).

Re: [Newbies] Re: Adding methods to Integers...
This is actually wrong. Only SmallIntegers are special [*]. What happens is this: When you add two SmallIntegers (like 3 + 4), and the result is a SmallInteger, the result is calculated in the bytecode directly. Otherwise, a regular send of #+ is performed. From there, everything else happens in the image, including conversion to LargeIntegers - see implementors of #+. Like, if the receiver was a SmallInteger, it tries the add primitive, which fails, and then the implementation of #+ in class Integer is invoked. This method then creates a large integer. For the implementation of all this see #bytecodePrimAdd and #primitiveAdd. You may have to load VMMaker first. - Bert - [*] Well, Floats are optimized a bit, and we have a plugin to speed up LargeIntegers, but this is all optional and doesn't matter in this discussion.

[Newbies] Re: Squeak Firefox plugin on Linux
You've lost me. The installer did put npsqueak.so into the plugins directory, but eToys still aren't working in Firefox. What is libXt? That's exactly the problem - until very recently, both Mozilla and Firefox linked to libXt by default. Now Firefox does not anymore. So our new version links libXt directly into the squeak plugin. It should be sufficient to install the new plugin, and manually run npsqueakregister. Or even manually create the symlinks from npsqueak.so into your browser's plugins directory (that's all npsqueakregister does). - Bert - begin:vcard fn:Andrew Dabrowski n:Dabrowski;Andrew email;internet:[EMAIL PROTECTED] tel;work:812 855-5470 x-mozilla-html:FALSE version:2.1 end:vcard ___ Beginners mailing list [EMAIL PROTECTED] http://lists.squeakfoundation.org/mailman/listinfo/beginners
