The Trunk: System-mt.1453.mcz
by commits＠source.squeak.org 17 Apr '24

Marcel Taeumel uploaded a new version of System to project The Trunk: http://source.squeak.org/trunk/System-mt.1453.mcz ==================== Summary ==================== Name: System-mt.1453 Author: mt Time: 17 April 2024, 10:43:17.752706 am UUID: d5ecd791-4890-e748-950c-809da8376186 Ancestors: System-mt.1452 For structured primitive errors, expose #errorName in its print-string to make the error table more readable (see index 52 in #specialObjectsArray). While ExceptionInFFICallError has both a custom name and an extra slot, you can use any custom instance of PrimitiveError to pass scoped error codes from failing primitives such as the existing #'operating system error' and its platform-specific error codes. However, you would need to reserve a new index in the error table and thus update the special-objects array. Therefore, custom VM plugins might want to choose an extra interface to communicate failed operations. For example, SqueakFFI uses #getLastError and #externalCallFailed to fabricate readable error messages. Not sure why we do it this way (see #ffiFail: in plugin code) ... the approach via PrimitiveError seems more elegant to me... and via PrimErrFFIMarshallingError there is even a way to use the new scheme. :-) =============== Diff against System-mt.1452 =============== Item was added: + ----- Method: PrimitiveError>>printOn: (in category 'printing') ----- + printOn: aStream + + self errorName + ifNil: [super printOn: aStream] + ifNotNil: [:nm | nm printOn: aStream].!

transparency, black, and PNG files
by Lauren Pullen 17 Apr '24

17 Apr '24

Hi List, I have a 32-bit Form I imported from a PNG without an alpha layer that has a black background for transparency, but this is what I get when I examine it in the inspector: self pixelValueAt: 1@1. 4278190080 . self pixelValueFor: Color black. 4278190081 . self colorAt: 1@1. Color transparent . self isTransparentAt: 1@1. false . self pixelValueFor: Color transparent. 0 . I feel like having #colorAt: answer transparent while #isTransparentAt: answers false is a bug.

News Squeak
by Ron Teitelbaum 16 Apr '24

16 Apr '24

Hello All, Our last news update was 6 years ago. https://news.squeak.org/ That is a very long time to have nothing happen! It is entirely my fault although I have been asking for someone to take it over. I haven't done it often enough. I'm doing it again now. HELP! Ok to try and do it a bit better. Why: because not everyone reads the mailing list. It is a good way to reach potential and existing users of Squeak to let them know what is going on. Small simple regular articles about what is happening is a great way to promote the squeak community and to give it more life. I still believe that news.squeak.org has real value and it would be great to have someone, who does read the mailing lists, post articles about what is going on. It doesn't have to be big events, just interesting ones that squeak users would want to know. The articles don't have to be long, just a paragraph or two and a picture would be nice. There are a ton of things that have happened in the past 6 years but we don't have to go backwards even just going forwards would help. Since news.squeak.org started we have had 750K views. our best month had 25K views. Our top article is this: https://news.squeak.org/2007/12/29/old-smalltalk-pics-from-parc-place/ with 35K views. Would someone or everyone that reads the smalltalk lists please step up and agree to periodically post articles to news.squeak.org? In other words: HELP! If you are willing to help please contact me and I'll give you an account on our wordpress site so you can start posting articles. I can also answer any questions and help get you started. Having more than one volunteer would be great. Maybe then we can reach our goal of one article a week! Thank you!!! All the best, Ron Teitelbaum News Team Leader

Anyone using FileMan package?
by Tim Rowledge 09 Apr '24

09 Apr '24

I was just taking a look at the FileMan package (https://github.com/mumez/FileMan) since I've heard it mentioned as having some improved file name handling. It looks like it would need a little mangling for Squeak 6 and it seems to have a difference in how "this string' asDirectoryEntry works that might be a problem. Current trunk Squeak will return nil if one tries to do 'nonexistentfilename' asDirectoryEntry but FileMan will create an FmDirectoryEntry; so any code that anticipates nil meaning "the file wasn't there" will have issues. Is anyone using this? Updating it? tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Useful random insult:- A titanic intellect... In a world full of icebergs.

monticello browser says it is updating SqueakSource...Xtreams when I save to a local cache
by gettimothy 03 Apr '24

03 Apr '24

Hi folks, I am in the process of undoing my rookie kludge in Xtreams where I stored my grammars in the PEGParser class alongside the other grammars. When I save to my local cache, the Monticello Browser says it is updating the squeaksource site. I checked and it appears to be fine. But I want to make sure I did not muddy up the project. cordially, t

Questions Loading Maui from SqueakMap
by Edwin Ancaer 03 Apr '24

03 Apr '24

Hello, I wanted to load Maui from SqueakMap but as I'm running a 6.0 image, there is no corresponding Maui verson in squeakmap. I first tried to load version 1.53, but that is giving following error: [image: mabase1.png] Then I tried the Head version, but that proposes met to merge code. Not being a specialist, I don't want to rush into this. Is it safe for the other applications in the image to start changing existing code? Which of the proposed options can I take best?.... [image: merging.png] Is there any chance for a Maui version for the 6.0 image, and if not, what is the best option for the proposed merges? Please don't see this as a complaint. Free time is scarce for everybody, so "We just don't have the time to keep up with all this" is a valid answer for me. Kind regards, Edwin Ancaer

Re: [squeak-smalltalk/squeak-object-memory] `Json` produces invalid JSON output for integer keys (Issue #109)
by Vanessa Freudenberg 01 Apr '24

01 Apr '24

The second should raise an error. Our dictionaries do not preserve insertion order so we don't even know which one is the duplicate. For the first case where it's unambiguous I'd find it more convenient to allow this and automatically convert the key to a string, just like `Association>> jsonWriteOn:` does (there is an argument for removing this method though, because unlike all other methods it does not by itself produce valid JSON) -- Reply to this email directly or view it on GitHub: https://github.com/squeak-smalltalk/squeak-object-memory/issues/109#issueco… You are receiving this because you are subscribed to this thread.
