wiki page for 'how to change default font'

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 How to change the system font to a custom TrueType font ? I managed to solve with the help of the following: http://wiki.squeak.org/squeak/5586 http://wiki.squeak.org/squeak/5584 http://wiki.squeak.org/squeak/5773 - system with russian (cyrillic) fonts The above documents helped a lot; specifically the document 5773 "how to setup Squeak with a cyrillic font", had an important note: "Switch your fonts This can be done from World->Appearance->System Fonts." That works indeed, if you set the various fonts (text font, menu font, list font, code font etc.) in the World->Appearances->System Fonts. I think this could be in its own wiki page: "How to change the default System Fonts" if such a doc does not already exist. I didn't find it on wiki.squeak.org but fortunately the other docs helped.

syntaxHighlightingAsYouTypeLeftArrowAssignment

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, Platform: squeak 4.19.5 with Squeak 4.6 or squeak 5.x with Squeak 6.0alpha I wonder whether it's possible to display the assignment operator '_' underscore as Left Arrow. "Cuis-Smalltalk" is doing this, looks very nice. I've found something on wiki.squeak.org : syntaxHighlightingAsYouTypeLeftArrowAssignment in preferences. Go to Menu -> Tools -> Preferences (or Menu -> Apps -> Preferences Browser) Search : syntaxHighlightingAsYouType (it's under "browsing') enabled syntaxHighlightingAsYouTypeLeftArrowAssignment enabled does not work : do I need "Shout" http://wiki.squeak.org/squeak/5700 is Shout still working in 4.6 ? I have the impression from the wiki.squeak.org page that there existed a package to display '_' as left-arrow but not sure whether it is still there.

Alto Sherif Smalltalk-72 "Legacy"
by stes＠PANDORA.BE 18 Jan '21

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 The font I use is a free font : Alto Sherif Smalltalk-72 "Legacy" http://www.kreativekorp.com/software/fonts/index.shtml I think the "Legacy" stands for the encodings of underscore as left-arrow, and circumflex (caret) as up-arrow. There are other fonts that do this, as for example the PETSCII encoding (on that same website) indicates the Commodore PET series of computers, had the same encoding of left-arrow and up-arrow where modern ASCII has its underscore and circumflex (caret). Presumably a wide range of computers in the 1960's and 1970's had those symbols on these positions.

two classes with the same name (Matrix issue)
by stes＠PANDORA.BE 11 Jan '21

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Platform: /usr/lib/squeak/4.19.5-3793/squeakvm Squeak4.6 of 11 December 2017 [latest update: #15117] Unix built on Jan 1 2021 12:28:22 Compiler: 5.15.0 platform sources revision 3793 VMMaker versionString 4.19.5 Issue: There exists a class Matrix subclass of Collection, it seems to have been implemented in 2002 by 'raok' ? Go to the Browser, select "Matrix" and browse, and one can see Matrix, subclass of Collection. When I open a Monticello Browser and add a repository: http repository: MCHttpRepository location: 'http://www.squeaksource.com/cakit' user: '' password: '' I can load the Computer Algebra Kit with the "Load" button. HOWEVER ... despite the fact that there's no warning in the Transcript, this will now result in 2 Matrix classes in the system. Go to the Browser, select "Matrix" and browse, and one can see Matrix, in the Computer Algebra Kit. It's a different class ... but a hybrid or 'merged' version, perhaps some sort of 'pose As' version of the original, replaced by the different and totally different subclass Matrix in the CAkit. Now what I can do, and that works, is before installing the Computer Algebra Kit, I can remove the class Matrix subclass of Collection. In fact I'm under the impression that I should do that. If you select Matrix subclass of Collection and from the menu, Remove class ('x') that works. In fact, I think it is more or less required to do so, because I suspect the steps that I did above, corrupt the image. The old Matrix class is no longer displayed as subclass of Collection, and the methods of the old class and comments are visible in the new class, but that makes no sense since the instance variables of the new class, are totally different ... Puzzled by this result. I think what I'm observing here is that if you load 2 classes with the same name, and with different implementations, what Squeak 4.6 is doing, looks like some sort of poseAs where the last class that is loads substitutes/replaces the first version ...
