What difference between this things. I know about Eliots post describing closures in Squeak, but it's too massive and so special to understand. Thanks. -- Andrey Larionov

Adding GLU library to OpenGL for Sqeuak
by Phua Khai Fong 10 Apr '09

10 Apr '09

Hi, I would like to know how to add the GLU library into OpenGL. I am using Cobalt actually but since I am new in this, I figured the beginners section is appropriate to post this. The functions in the GLU library I want to use are the ones related to NURBS. Please let me know where to start and how to accomplish this task. Thank you.

Setting up squeak on Ubuntu
by Jerome Peace 10 Apr '09

10 Apr '09

I finally found the first things that worked. Installing Squeak on Ubuntu >From the Ubuntu menu (top leftmost icon) Select the last item: Add/Remove The application window opens: select Show: all available applications. In the search box type: squeak You get one option from www.squeak.org. (It rates two stars. We have not made a big dent in the outer world. Sigh.) Check the box next to it. Press the apply changes button at the bottom left. Give permission to install squeak despite its copyright restrictions Give your administrative password when asked. It downloads five packages One to deal with binformat The other four are the vm (today I got 3.9.3 and a 3.9 sources and change and image files based on sq 7067). Under the application menu>education I now have two choices one for etoys which I installed before and the other for squeak. I also have one choice in the application menu>programming. If I click gently on the educational menu (as opposed to dragging thru the menu to the submenu) the sub menu stays up. Then I can go and right (or middle?) click on the squeak item and be offered a launcher on the desktop. I can get properties for the launcher. Select the launcher tab, then modify the selection. Which I do by giving it a file name relative to my home folder. Actually I give it the filename of a link in my home folder which points to the right image. Later I can change which image I mean by changing the link. As long as a link is named what the launcher expects I don't have to change the launcher. To clear the desktop I just moved the launcher into a different folder. The squeak shell script explains the options and such so I found and studied that. ===== Thats about it. By some clever manipulation of the launchers I can sub the images I want for the standard image. I still have most of my ignorance intact. Though I expect to be losing it bit by bit to the school of hard knocks. Its not obvious where things will be stored when saved. So far text from saved workspaces turn up as files in the directories of the original image not the links. It seems to me when squeak saves something it should at least report back what it saved where. Thank everybody for their clues. I haven't used all of them yet but the time will come. Yours in curiosity and service, --Jerome Peace

What's the relationship between scripts and methods?
by Steinar Bang 08 Apr '09

08 Apr '09

The scripts, converted to code, kind of look like like methods. What are the relationship of scripts and methods? Are scripts instance level methods? I see two possible implementations for this: - the eToys objects could have a system dictionary of methods as an instance value? - eToys objects could be singletons of a new class created on the fly? Or are scripts code blocks associated with the instance in some other way? - Steinar

Getting at the squeak beneath eToys?
by Steinar Bang 08 Apr '09

08 Apr '09

Is there a way to get at the underlying squeak system when working in an eToys image? I've looked for menu entries to on open a System Browser, but I haven't found any. (I guess I could start a bare bones squeak, but then I won't have eToys... or would I...?) - Steinar

Opening a Changes file with another image
by Rob Rothwell 07 Apr '09

07 Apr '09

Hi all, We have an image that won't open anymore...and being the terrific professionals that we are, have no other version of the source code than what might be in the changes file! Is it possible to "open up" a changes file with a different image and see what you can recover? Just wondering... Thanks, Rob
