How does ImageSegmentLoader>>readObject work?

Hello this is a follow up mail on loading a project file (*.pr) saved in Squeak 3.10.2 [1] into Squeak 6.0a-#18000 [2] The code breaks at ImageSegmentLoader>>readObject [3] I'd like to find out which class causes this problem. readObject | header oop nWords class format | header := self readUint32.

Dynamic essay project MorphLayoutArticle on Bob's SuperSwiki?
by H. Hirzel 28 Jun '18

28 Jun '18

Hello Is there a backup-copy/mirror available of the MorphLayoutArticle project which was on Bob's SuperSwiki? [1] Regards Hannes ---------------------------------- [1] http://wiki.squeak.org/squeak/2141 How to lay out submorphs Please read the excellent dynamic essay project MorphLayoutArticle (broken link) on Bob's SuperSwiki. Every Morph now has the capability to layout it's submorphs. (Previously, only the AlignmentMorph could implement layout policies. AlignmentMorph is still available because of compatibility reasons and some utility methods it implements.

squeakbyexample book/website needs love
by tim Rowledge 28 Jun '18

28 Jun '18

One of the online resources we've been listing in Help for a long time is the Squeak By Example book that was available on the (duh!) squeakbyexample.org site. Sadly if you hit that URL these days you get redirected to a github repository. It's nice that all the resources are there but I can't help thinking that new users wanting to read the book might be a bit confused to find that they have to learn enough git-fu to be able to 'make' the book. Is it practical to have a pdf file provided somewhere? Or any other much simpler way to read the book? tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Strange OpCodes: BYEBYE: Store in Write-Only Storage

Squeak digests -- nothing here since June 14th?
by Donald Major 27 Jun '18

I’m asking because it’s been a little too quiet on my end. Can someone please kick whatever server or service is falling down on the job? I need my Squeak chatter feed. 😊

I represent the machine state at the time of an interrupted process. I also represent a query path into the state of the process. The debugger is typically viewed through a window that views the stack of suspended contexts, the code for, and execution point in, the currently selected message, and inspectors on both the receiver of the currently selected message, and the variables in the current context. Special note on recursive errors: Some errors affect Squeak's ability to present a debugger. This is normally an unrecoverable situation. However, if such an error occurs in an isolation layer, Squeak will attempt to exit from the isolation layer and then present a debugger. Here is the chain of events in such a recovery. * A recursive error is detected. * The current project is queried for an isolationHead * Changes in the isolationHead are revoked * The parent project of isolated project is returned to * The debugger is opened there and execution resumes. If the user closes that debugger, execution continues in the outer project and layer. If, after repairing some damage, the user proceeds from the debugger, then the isolationHead is re-invoked, the failed project is re-entered, and execution resumes in that world. !
