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

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.

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.

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

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.

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).

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

by kmo

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

Look carefully, they are both FileReferences, the UI is different. Also, explore the difference between the working directory and the image directory: FileLocator workingDirectory absolutePath. FileLocator imageDirectory absolutePath. The working directory depends on how the image was launched.

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

by Esteban Lorenzano

Hi, short answer: you can't (and you shouldn't) :) long answer: conceptually, a presenter does not has an extent because it is not a component by itself, is just a set of other presenters arranged into a layout. However, that does not means you can't know the extent where your athens component will be drawn! Basically, you cannot know the presenter size (or position), but you can know the extent assigned to your athens canvas because the renderer will call your drawBlock with a canvas already initialized. So, you can do something like: athensPresenter := self newAthens drawBlock: [ :aCanvas | | extent | extent := aCanvas surface extent. ... etc ... ]. But! This is poorly documented and even less used, so there may be missing parts (both bugs and things I didn't think on when I implemented the component). Please let me know if this is working for you :) cheers!

How to get dimensions (extent) of a SpPresenter

by kmo

I'm porting a little Morphic geometry program from Morphic to a Spec 2 application using GTK. I need to draw a shape in an SpAthensPresenter but to draw it I need to know the current dimensions (extent) of the presenter so it can still work OK even when the window is resized. The old Morphic version also used An Athens canvas but I had no problem then as a morph has an extent method that provides this information. But now that I can't use a morph I find that the extent method of an SpPresenter always seems to answer nil. Is that right? How d you get the current size of a presenter? Is it a bug? I'm using a very recent Pharo 9 image and headless VM on Linux.

David There is no magic. You should also consider that pharo-ui is a shell script and that you can also read it and learn. The vm is an executable and it needs an image and it cannot guess where you put it.

David with the script Stef showed you just downloaded the VM. If you want to download the image also you can use https://get.pharo.org/90+vmLatest .

Re: Bootstrap4 package or Willow

OK this sounds wierd - I installed one more image only with astares/Seaside-Bootstrap4 then astares/Seaside-Bootstrap4 examples started working fine on both images. I continued to work just fine even after I removed the second image Note i am installing thru PharoLauncher, both images are in their own folder, However in settings Iceberg is pointed to a common folder in c:\iceberg (I am using windows - this is to get past the long filenames problem) Sanjay Minni wrote > Hi > > If I install both i.e. > > A. gh:astares/Seaside-Bootstrap4 ... and ... > B. gh:ba-st/willow-bootstrap > > then why is astares/Seaside-Bootstrap4 examples clobbered. how can this be > set right: > > <http://forum.world.st/file/t368721/AstaresBS4-1.jpg> > > <http://forum.world.st/file/t368721/AstaresBS4-2.jpg> > > > > ----- > cheers, > Sanjay > -- > Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html ----- cheers, Sanjay -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

UK Smalltalk User Group meeting - Wednesday May 26th

by Giovanni Corriga

The next meeting of the UK Smalltalk User Group will be on Wednesday, May 26th. Caffeine ( https://caffeine.js.org ) is a livecoded integration of the SqueakJS Smalltalkvirtual machine with the Web platform and its many frameworks. Craig Latta will show the current state of Caffeine development through live manipulation and combination of those frameworks. The primary vehicle is a Caffeine app called Worldly, combining the A-Frame VR framework, screen-sharing, and the Chrome Debugging Protocol into an immersive virtual-reality workspace. Craig Latta ( https://blackpagedigital.com ) is a livecoding composer from California. He studied music at Berkeley, where he learned Smalltalk as an improvisation practice. He has worked as a research computer scientist at Atari Games, IBM's Watson lab, and Lam Research. In 2016 he began combining Smalltalk technologies with the Web platform, with an emphasis on spatial computing. He is currently exploring spatial audio for immersive workspaces. Given the current COVID-19 restrictions, this will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/UKSTUG/events/cbklbrycchbjc/ ) to receive the meeting details. Donât forget to bring your laptop and drinks!

Now, since you both got plain and secure connections working, there is no fundamental problem for either type, or the rest of your setup/situation. You seem to have hit some edge, resulting from a small configuration difference in one of the server you are trying to log in to. You say you get a "SSL Exception: connect failed [code:-5]" - we have to find out what the -5 means. As you can see in ZdcPluginSSLSession>>#primitiveSSL:connect:startingAt:count:into: these errors are not specified or explained. We will have to look into the SSL plugin C code for that, and maybe/probably consult the Windows documentation for the system calls used. Apart from certificate issues, it could also be a cipher issue (as in something specific is required but not available). Sven PS: to configure the server (version 13.2), I added the following to postgres.conf ssl = on ssl_cert_file = '/Users/sven/.ssh/ssl-cert-snakeoil.pem' ssl_key_file = '/Users/sven/.ssh/ssl-cert-snakeoil.key' the ssl-cert-snakeoil I took from a standard Ubuntu postgreSQL installation. In pg_hba.conf the first field allows you to control access over different connection types: - host = both plain & secure - hostssl = only secure - hostnossl = only plain

Hi David, for M1 we have Pharo 9 compatible VMs, you can download them using Zero Conf or directly. For the latest: - wget -O - https://get.pharo.org/vmLatest90 | bash - http://files.pharo.org/get-files/90/pharo-vm-Darwin-arm64-latest.zip For the stable: - wget -O - https://get.pharo.org/vm90 | bash - http://files.pharo.org/get-files/90/pharo-vm-Darwin-arm64-stable.zip If you are scripting the download I recommend using ZeroConf. For Pharo 8, we don't have a M1 native version, because Pharo 8 requires changes in the image to support the newer VMs. We have plans to backport the changes in the future, now we are putting all efforts in the release of Pharo 9. However, if the community consider it, we can switch priorities but it is not magical; we will need to leave something aside. Also, future versions of the Pharo Launcher will have support for detecting the architecture. In the meantime, Pharo 8 / 9 can be used without a problem with Rossetta, although the performance is not ideal. Tell me if you have any problem.

Hi David, I do not own a M1 macBook but I read on discord that people are successfully using it. You might to take a look at : https://thepharo.dev/2021/02/16/first-apple-m1-pharo-version/ I think that you can download the last version here (instead ot the one given in the link above) : http://files.pharo.org/vm/pharo-spur64-headless/Darwin-arm64/ I'm afraid you'll need to find a M1 user if these links do not help you (come on discord <https://discord.gg/QewZMZa> to find some) Cheers, Harald Le mer. 19 mai 2021 Ã 01:54, David Pennington <david(a)totallyobjects.com> a Ã©crit : > Hi there.

Re: P3 connection error

Hi, Since you can connect to 3 of the 4 machines, both over plain and tls, it basically works. You will have to find out what is different in the host configurations of the servers. It could be a certificate issue like you suggest, I don't know. I am guessing you are on Windows ? Tomorrow I will try to test plain and tls connections on my machine.
