How should XMLHTMLParser handle strange HTML?
by PBKResearch April 3, 2020

April 3, 2020

Hello I have come across a strange problem in using XMLHTMLParser to parse some HTML files which use strange constructions. The input files have been generated by using MS Outlook to translate incoming messages, stored in .msg files, into HTML. The translated files display normally in Firefox, and the XMLHTMLParser appears to generate a normal parse, but examination of the parse output shows that the structure is distorted, and about half the input text has been put into one string node. Hunting around, I am convinced that the trouble lies in the presence in the HTML source of pairs of comment-like tags, with this form: <![if !supportLists]> <![endif]> since the distorted parse starts at the first occurrence of one of these tags. I don't know whether these are meant to be a structure in some programming language - there is no reference to supportLists anywhere in the source code. When it is displayed in Firefox, use of the 'Inspect Element' option shows that the browser has treated them as comments, displaying them with the necessary dashes as e.g. . I edited the source code by inserting the dashes, and XMLHTMLParser parsed everything correctly. I have a workaround, therefore; either edit in the dashes to make them into legitimate comments, or equivalently edit out these tags completely. The only question of general interest is whether XMLHTMLParser should be expected to handle these in some other way, rather than produce a distorted parse without comment. The Firefox approach, turning them into comments, seems sensible. It would also be interesting if anyone has any idea what is going on in the source code. Thanks for any help Peter Kenny

This interpreter (vers. X) cannot read image file (vers. Y)
by HernÃ¡n Morales Durand April 2, 2020

April 2, 2020

Hello, I'm using Pharo images obtained from get.pharo.org for different OSes (GLIBCs). Is there any way to query VM and image file version from CLI? Or Is there any table matching the OS versus Supported/Unsupported VM + Image? Cheers, HernÃ¡n

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

by Alistair Grant 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
