It is always rewarding to read about people using The Cuis book to learn Smalltalk. <blockquote type="cite" cite="mid:CAKDUZVi=9T6hTDb0y63T5SiDaOSUOGHeURCZsZcyW49rqZoGfw@mail.gmail.com">and I've come across a couple of small issues - I've tested these with the latest code from git on both an intel mac and a 64-bit raspberry pi and I've even compared to squeak where I think it makes sense. The first one is the when I set the size of the GUI elements to something other than default I can see a gap on the left and the right hand sides between the top of the window and the title bar, I've attached a small screen shot so you can see what I'm </blockquote> I think we all observed that. It is likely a rounding error in the title bar morph revealed when VectorGraphics was set as default in Cuis. I will try to look at it. But you don't need to worry about it. <blockquote type="cite" cite="mid:CAKDUZVi=9T6hTDb0y63T5SiDaOSUOGHeURCZsZcyW49rqZoGfw@mail.gmail.com">The second one is I don't seem to be able to make a LinkedList. I get a message not understood. So in squeak if I do an inspect on the following it works: (LinkedList new) add: 1; add: 2; add: 3; yourself. </blockquote> To a LinkedList isntance you can only add object kind of Link. You can add any sort of object. For example: LinkedList new add: (Link new); add: (Link new); yourself However Link is an abstract class not capable to hold data for the link. It only provides the mechanism to navigate to the next link in the LinkedList (#nextLink message) So to make anything useful with LinkedList, you must subclass Link and add the appropriate attributes to hold the data you want for a Link. For example in DrGeo, to sample a Locus I use a LinkList and each sample of the Locus is a sort of Link with the appropriate attributes related to a sample, some of the attributes are only cache for optimization: Link subclass: #DrGLocusSample instanceVariableNames: 'abscissa pointScreen pointWorld offScreen exist' classVariableNames: '' poolDictionaries: '' category: 'DrGeo-Item-Views' <blockquote type="cite" cite="mid:CAKDUZVi=9T6hTDb0y63T5SiDaOSUOGHeURCZsZcyW49rqZoGfw@mail.gmail.com">Finally the Cuis-Smalltalk book says that the following will return false, it does in squeak but in Cuis it returns true. 'hello' == 'hello' copy </blockquote> Good catch! Thanks. I think it is a bug related to the recent adoption of Unicode as the default string representation in Cuis because : (String withAll: 'hello') == (String withAll: 'hello') copy => false Adoption of Unicode as the default string representation in Cuis is an important change impacting many area and external package of Cuis. So it mY take a few cycles to get it bug free but it is a big win in the long term. Thanks a lot for your detailed reports.
