Where to 'declare' symbols
by John Almberg 14 Aug '07

14 Aug '07

I want to eliminate a 'magic number' used by methods in a single class. I'd like to do that by creating a symbol that would be available to all the methods in the class. Where and how should I create such a symbol? I can't seem to find an example anywhere. Thanks: John

Mod operator?
by John Almberg 14 Aug '07

14 Aug '07

Sorry for this simple question, but I can't seem to find the mod operator. As in, "what's the remainder after doing division?" Thanks: John

adding methods to a class at runtime
by Mark Volkmann 14 Aug '07

14 Aug '07

Is it possible to write code that adds methods to a class at runtime. In particular I'm thinking about something like attr_accessor in Ruby which adds get and set methods for instance variables so you don't have to write them. Thanks to everybody who has answered my questions so far! --- Mark Volkmann

I¹m having no luck at all. I¹m trying to build from sources but the system keeps complaining that gcc can¹t create executables. I tried doing it as root but it made no difference. This is ridiculous. Everything is fighting against me. I don't want to have to debug my C development environment. I just want to run Squeak! Why is it that everyone else has no problem running Squeak 3.9 under Feisty Fawn??? This is driving me crazy. What binaries/libraries are the Squeak VM installation looking for?

It works without problems here. Good luck Enno

Ubuntu Linux

I¹m trying to install Squeak on a *fresh* installation of Ubuntu Linux 7.04 (Feisty Fawn) using... Squeak-3.9-8.i686-pc-linux-gnu.tar.gz ...from Squeak.org. But it complains... ³No binaries/libraries found for i686-pc-linux-gnulibc1.² I am completely baffled by how this can fail, unless no one on this planet has ever installed Squeak on Feisty Fawn. Can somebody give me a clue? Thanks, Richard

deploying Squeak applications
by Mark Volkmann 13 Aug '07

13 Aug '07

How are Squeak applications typically deployed to users? Is there a way to create an image that runs a given method when double-clicked? Is there a way to reduce an image to contain only the classes used from a given starting class? --- Mark Volkmann

No, not install from source. As I said, I tried to install Squeak-3.9-8.i686-pc-linux-gnu.tar.gz ...which is the binary download from Squeak.org. And I¹m using 32-bit Linux (Ubuntu). The Synaptic package is out of date--the latest version it has is 3.8. I need 3.9 (because I have development images of Seaside based on 3.9). This is really goofy. What can possibly be wrong with my fresh Feisty Fawn installation???

Can somebody give me a clue? Squeak runs on Ubuntu 7.04 without problems here. You download a tar.gz, so you want to install from source? Try a pre-compiled Synaptic package instead. (Could be difficult on a 64bit Linux) If you want to build from source, dont forget to install all the development tools before. Go to synaptic and install the "build-essential" package. Hope that helps Enno

class name scoping

What happens in Smalltalk if multiple categories contain a class with the same name? Is that allowed? If so, how do you specify which one you want? --- Mark Volkmann

Generating a predictable 'atRandom' result for testing
by John Almberg 13 Aug '07

13 Aug '07

I'm trying to write a test for a method that uses atRandom to choose a random integer. Is there a way to seed the random number generator to generate a predictable sequence of numbers, so I end up with testable results? TIA: John

Hello www.squeakland.org/ may be of more use to you then www.squeak.org as it's more about squeak in education. What tutorials are you using? I'm working my way throw this one: http://squeak.preeminent.org/tut2007/html/index.html and am finding it very usful. Also the book: Squeak: Learn Programming with Robots, may be of use to you.
