Ballooning image size! Approaching 400MB
by Russ Whaley April 1, 2020

April 1, 2020

My image size keeps growing and growing. I've been scouring Google and mailing lists, trying to find a solution. Observables: - Running this 'query' shows I have a whole lot instances of Objects I've created that are not "releasing". There are 65000 instances of one Object/Class, and 350,000 of another. (there are more, these are just the big hitters). (Object allSubclasses collect: [ :aClass | aClass -> aClass allInstances size]) sort: [ :a :b | a value > b value ]. - Each time I load my app/UI - which creates/loads another 5000 of one object and 25,000 of the 2nd object - my Class>>instanceCount(s) keep growing and so does my image size. - I've done: - Smalltalk garbageCollect. - Smalltalk garbageCollectMost. - 10 timesRepeat: [ Smalltalk garbageCollect]. (many, many times) Somehow, these instances I create are not 'releasing'. All of my Classes are direct subclasses of Object. Interestingly enough, all these objects sit in a single collection for the high-level model - and there are only 67 instances of that Object... here's the hierarchy: MyTunes - instance holds a Dictionary of Libraries, rootFolder and tags collection Library - instance(s) hold Dictionary of Artists & Playlists, tags collection, and MyTunes reference Artist - instances hold Dictionary of Albums, and Library reference Album - instances hold Dictionary of Tracks, and Artist reference Track - instances hold TagInfo, Album reference TagInfo - instances hold fileReference and ByteString of ID3 tag info. PlayList - instances hold Dictionary of Tracks, Library reference. Here's my start code in my app... (I don't know how to use SpApplication, SpPresenter and my model(s) together - this may be part of the problem).. start "Override this to start your app" "*** I don't know how to use SpApplicatoin, SpPresenter and my model MyTunes ***" | myTunes tmpLibrary myPres | "where do I store the model -> MyTunes?" myTunes := MyTunes new. "this is just for testing, but the actual re-load of the library takes 15-20 minutes (60,000 files!)" tmpLibrary := myTunes readLibraryFromSTONfile. myTunes addLibrary: tmpLibrary. "where do I store the presenter -> MyTunesPresenter? " myPres := MyTunesPresenter on: tmpLibrary. myPres openWithSpec. While I'd love help with my App/Pres/Model - my first goal is to stop the rapid growth of my object. Questions? Thanks! Russ Whaley (USA, Ohio) -- Russ Whaley whaley.russ(a)gmail.com

Unicode migration from SmalltalkHub to Github
by Alistair Grant April 1, 2020

April 1, 2020

Hi Sven and All, We have a need to migrate the Unicode library (http://smalltalkhub.com/#!/~Pharo/Unicode) to github (for our release tagging process). I've imported the code, with full history, in to: https://github.com/feenkcom/pharo-unicode If there's no suggestions / objections, I'll request that it be added to https://github.com/pharo-contributions. Thanks, Alistair

[ANN] Complishon: efficient heuristics for code completion
by Guillermo Polito March 31, 2020

March 31, 2020

Hi all, Since yesterday, Pharo 9 contains a new alternative code completion engine. The idea behind this engine is to be pluggable, to be efficient and to be more accurate through the introduction of heuristics. The completion engine implements a couple of nice heuristics, like - chances are `anOrderedCollection` references an ordered collection - chances are you want to auto-complete messages implemented in the same package New heuristics can be added easily (I was playing with plugging heuristics using type inference like roel typer). If you want more details, check the blogpost: https://masteringobjects.wordpress.com/2020/03/30/complishon-efficient-heur… <https://masteringobjects.wordpress.com/2020/03/30/complishon-efficient-heur…> And if you have ideas for new heuristics that could make your Pharo experience better, let us know! Cheers, Guille

What is the status of SUnit in Pharo?
by Tim Mackinnon March 30, 2020

March 30, 2020

Hi guys - whatâs the status of SUnit in Pharo, are fixes supposed to be applied upstream to some master SUnit project or do we propose fixes/improvements locally? For example the method: should: aBlock raise: anExceptionalEvent whoseDescriptionIncludes: substring description: aString ^self assert: (self executeShould: aBlock inScopeOf: anExceptionalEvent withDescriptionContaining: substring) description: aString The #executeShould:â¦. Is implemented in the subclass TestCase and not TestAsserter (is that a local pharo thing to do with Traits?) - the code critic shows an error - and it seems the Calypso doesnât have an option to call these things out anymore? But equally poking more - while I REALLY LOVE the fact that assert:equals: give me a useful diff browser on a failure - I REALLY HATE that there are many other examples where I donât get the same useful UI - e.g. #should:raise:whoseDescriptionIncludes:description: is awful???? Given our community mostly invented unit testing - why is it so poorly fleshed out to do the right thing? Along the same lines - when trying to write descriptive tests, why canât I easily assert the existence of a substring in something and get an equally useful message? I recall mentioning this a few years ago and donât remember why I got shot down - but honestly, this stops us writing helpful tests and keeps us in the stone ages? Can we modernise this state of affairs so things are like the amazing diff browser (which Iâm assuming is some sort of hack? Is the debug window pulling apart a TestResult to do this - am interested in how it does this, as I couldnât figure it out?) Tim

[Spec] Min script browser
by Hilaire March 30, 2020

March 30, 2020

Hi, I am experimenting Spec to write a DrGeo user scripts browser (in DrGeo scripts are classes). The layout and widgetery is so far ok (see screenshot). Nevertheless I have issue to keep synchronized the compiled methods in the Spec list, a recompiled method when the user edit its code and save it, then the source code in the code widget. Indeed when the user press save to keep the code it is compiled fine but the Spec list still hold what I guess is another instance of the compiled method. My attempt to manage this situation makes my code to look like shit. How will you manage this to keep up to date and synchronized the script information in the different Spec widgets? Thanks Hilaire -- Dr. Geo http://drgeo.eu

Autocompletion shortcut
by Vitor Medina Cruz March 28, 2020

March 28, 2020

Hi there, Is it possible to change autocompletion shortcut to ctrl + space instead of tab or shift + space? Every other tool uses ctrl + space, I would like to use it on Pharo also. Thanks, Vitor

Re: [Pharo-users] Test Completion has been added to Pharo 8 - please test!

Hello, I didn't find the controller option in Pharo 8, and I really want to use this autocompletion test, something has changed?
