How to debug why external library isn't loading with UFFI or appears not to be ?

by recursive68＠gmail.com

What's the best way to debug whether an external library is being loaded or not with UFFI ? I can't tell if it is or not, and nothing is showing up in the pharodebug.log. It's being loaded with the unix64LibraryName method. Thanks

Sure it is. You have all the information in the pdf. You can load the tool and nour can explain it to you in case.

Re: How to get dimensions (extent) of a SpPresenter

by Esteban Lorenzano

Hi, So, I was able to reproduce your problem : for some reason, cairo does not answer a correct surface extent while in x11 (I didn't noticed before because I use wayland). I can hack a solution (and I will), but have fear that will cause future problems :/ Anyway, I will commit a fix and you will be able to use the surface extent message.

Announcements on Traits methods injection ?

by LABORDE Pierre

Hello all ! I'm looking for Announcements related to Traits which are triggered when classes methods from a uses Trait are injected into a Classe (of course using this Trait). I haven't find equivalent to that, there is Announcement when classes methods are edited into a Trait but not into a Traits user. For the moment I'm using a custom pragma in my Trait class methods to have the information about the classe method modification but when the pragma is triggered from the Trait, Trait users aren't not yet updated (methods are not yet injected or linked and not available to use). After when users are updated (with adding the classes methods from the Trait) the pragma is not triggered. Thanks for your help ! Cheers, Pierre

Hi Estaban. Thank you for your helpful and prompt replies to my problem. Unfortunately, your code does not work for me. I pasted your code into a playground.

Re: Creating tests for the TinyBlog tutorial

by Sebastian Jordan

When you already have a package with a name "XXX" and you create a new class with its package name as "XXX-YYY", Pharo automatically detects "YYY" as a tag for the package and not as a new package. That is your problem. Your class TBPostTest is not in a package that ends with "-Tests". It is in "TinyBlog" package with the tag "Tests" ________________________________ From: Michael Burns via Pharo-users <pharo-users(a)lists.pharo.org> Sent: 24 May 2021 18:00 To: pharo-users(a)lists.pharo.org <pharo-users(a)lists.pharo.org> Cc: Michael and Mary Burns <michaelburns(a)mac.com> Subject: [Pharo-users] Creating tests for the TinyBlog tutorial In TinyBlogEn-gitc55a88d.pdf on page 11 (2.7 Post Queries): TestCase subclass: #TBPostTest instanceVariableNames: '' classVariableNames: '' package: 'TinyBlog-Tests' Every time I save this new class, it ends up in the TinyBlog package, not TinyBlog-Tests.

I think the speed difference comes from the different VM. P9 runs natively on M1. P8 does not run yet natively on the M1, meaning it runs on top of rosetta (which virtualises x86 at the expense of some performance degradation). > >> I have got caught up in a simple file operation - I am trying to rename a file and `I have come u with the following difference. > > I do not get what is the error. > Do you have a script to reproduce it. > We can only fix what we can reproduce. Take into account that the UI on P9 has been through a huge effort to use Spec2 and a new iteration of the original moldable GT tools on top of Spec2.

Re: How to get dimensions (extent) of a SpPresenter

by Esteban Lorenzano

Well, I noticed that it was working on gtk backend but not in morphic this works perfect: exampleResizing | extent | extent := 350@300. SpAthensPresenter new application: (SpApplication new useBackend: #Gtk); surfaceExtent: extent; drawBlock: [ :aCanvas | | paint surface | surface := aCanvas surface. paint := surface createLinearGradient: { 0->Color red. 1->Color green } start: 0@0 stop: surface extent. surface clear. aCanvas setPaint: paint. aCanvas drawShape: (0@0 corner: surface extent) ]; openWithSpec. but it does not work if you change the backend for morphic. Anyway, I submit a fix: https://github.com/pharo-spec/Spec/pull/1075 It will be in image soon :) Esteban On May 24 2021, at 8:06 pm, kmo <voxkmp(a)gmail.com> wrote: > I should also point out that nothing works unless I also set a surfaceExtentwhen the presenter is set up - > > initializePresenters > rosesAthensPresenter := RosesAthensPresenter new. > rosesAthensPresenter surfaceExtent: 400 @ 400. > rosesAthensPresenter drawBlock: [ :aCanvas | > | paint surface | > surface := aCanvas surface. > paint := surface > createLinearGradient: { > (0 -> Color blue). > (1 -> Color black) } > start: 0 @ 0 > stop: 300 @ 300. > surface clear. > aCanvas setPaint: paint. > aCanvas drawShape: (0 @ 0 corner: 300 @ 300) ]. > > > > > -- > Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html >

I should also point out that nothing works unless I also set a surfaceExtent when the presenter is set up - initializePresenters rosesAthensPresenter := RosesAthensPresenter new. rosesAthensPresenter surfaceExtent: 400 @ 400. rosesAthensPresenter drawBlock: [ :aCanvas | | paint surface | surface := aCanvas surface. paint := surface createLinearGradient: { (0 -> Color blue). (1 -> Color black) } start: 0 @ 0 stop: 300 @ 300. surface clear. aCanvas setPaint: paint. aCanvas drawShape: (0 @ 0 corner: 300 @ 300) ]. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: How to get dimensions (extent) of a SpPresenter

I'm afraid it still doesn't work for me. If I have a drawBlock like this: drawBlock ^ [ :aCanvas | | paint surface | surface := aCanvas surface. paint := surface createLinearGradient: { (0 -> Color blue). (1 -> Color black) } start: 0 @ 0 stop: aCanvas surface extent. surface clear. aCanvas setPaint: paint. aCanvas drawShape: (0 @ 0 corner: aCanvas surface extent) ] I get just a blank canvas.- nothing is drawn. If I replace the aCanvas surface extent with a fixed size like this: drawBlock ^ [ :aCanvas | | paint surface | surface := aCanvas surface. paint := surface createLinearGradient: { (0 -> Color red). (1 -> Color green) } start: 0 @ 0 stop: 300 @ 300. surface clear. aCanvas setPaint: paint. aCanvas drawShape: (0 @ 0 corner: 300 @ 300) ] then it works. Any ideas what i might be doing wrong? -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
