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.

Discuss & Review | Faster ProcessExplorer through AllProcesses list
by Taeumel, Marcel 03 Apr '24

...instead of "Process allSubInstances". The caveat is this: process creation gets a little bit slower while accessing the list of runnable *and* waiting processes gets about 40x faster: [ [] newProcess terminate ] bench. AFTER: '140,000 per second. 7.13 microseconds per run. 35.02 % GC time.' BEFORE: '224,000 per second. 4.47 microseconds per run. 4.38 % GC time.' [ aProcessBrowser updateProcessList ] bench. -- allow quick updates AFTER: '4,410 per second. 227 microseconds per run. 77.34453 % GC time.' BEFORE: '118 per second. 8.47 milliseconds per run. 2.59792 % GC time.' Why do we need this? If you have an auto-updating ProcessBrowser running in the background while doing time-sensitive benchmarks, you want a fast ProcessBrowser :-) Please see the attached change set. Thanks to Leon and Eliot for the hint! Best, Marcel

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

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.

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

Looking at https://www.json.org/json-en.html & https://jsonlint.com/ I think the expectation is that the key must be a string and the value must be the json-ised value, so ``` Dictionary new at: 1 put: 2; asJsonString ``` should result in an error. Consider the first EBNF diagram on https://www.json.org/json-en.html - it can be simplified for this case to { string : jsonised-value}. Since we're exceptionally clever we could consider doing "make the key be a string of whatever we have" _except_ that trying to reliably convert non-string keys might open up entire pallet-loads of worms. What if somebody is making dictionaries where the keys are complex objects? Might also want to check on STON as well (https://wiki.squeak.org/squeak/6504). If we're attempting to produce sometihng that meets a standard we should probably actually meet the standard... -- 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.

drawing on morphs, damage recording, and canvas origin
by Lauren Pullen 30 Mar '24

30 Mar '24

Hi List, Easy question first. #refreshWorld warns not to use it often because of damage recording... but it doesn't say what to use instead. What is the correct method to mark a morph damaged? (I'm rendering a static 3D scene with a movable camera, so I only need to redraw it on demand by the camera.) Whenever I draw on a morph I always forget I need to offset coordinates by the morph's origin, so things end up getting drawn in the top left. I tend to open morphs in hand, so it draws correctly until I drop it back into the world. Why does the canvas in #drawOn: have a different origin depending on if you're holding the morph or not?
