uFFI ffiCall return value
by TomaÅ¾ Turk May 10, 2021

May 10, 2021

Dear all, Should the method that calls Object>>#ffiCall: and variants always return the result of this call? For instance, in uFFI book, there is a method abs: defined as FFITutorial class >> abs: n [ ^ self ffiCall: #( int abs (int n) ) ] on page 16, however FFITutorial >> abs: n [ self ffiCall: #( int abs (int n) ) ] on page 52 doesn't have an explicit return ^. The book, however, in most of the examples uses the explicit return. What is the recommended approach? Thanks, Tomaz

Is there any way to display the Class Hierarchy as a Diagram or a indented list. Even for all the classes in a package will do. ----- cheers, Sanjay -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

[fus] Early march sync
by hogoww May 5, 2021

May 5, 2021

Hello, In today's sync we talked about the idea, progress, paper planing. Idea: Basically the same as the previous mail so I'll not detail it here. The Slides are trying to give some details & a global view. They are, however not well ordered, and an inlining problem is missing. I'll update them quickly this afternoon, and send them back, hopefully this will help. Progress: I've done the poc to extract & graft a method. (details in slides/mail) Paper planning. 2 papers planned (possibly 3 If I were to dream a bit) First paper for GPCE on Transpiling & mutating tests. I'm putting a very short description to see that we all agree and that I'm not mistaken. The point is to test *Slang*. We are translating the tests and looking for asynchronicity for the test execution between the simulation & binary. This allows that the Slang compiler preserve the semantics. 2nd Paper on incremental compiler development see Slides & previous mail. A possible title would be: "Test driven incremental development of a compiler using a software" 3d Test prioritization Possible heuristic on test prioritization One is hinted in the last slide. Noury offered another one which is to focus on getting fast green tests. However this would require a new state of the art for a different domain. Next up: - Work on paper - Finding some mutations to apply on tests and classify them - Try to get some numbers on results ! Pierre

Creating an SDL (OSWindow) window without showing the pharo interface
by kmo May 3, 2021

May 3, 2021

Does anyone know how to get an OSWindow window to open from Pharo without showing the pharo IDE? I thought the headless VM might do this. So I downloaded the latest headless VM and Pharo 9. Then if I issue the command line / pharo-ui Pharo.image eval OSWindowWorldMorph new open/ I get an SDL window but also the pharo user interface which I don't want. But if I try /pharo Pharo.image --no-quit eval OSWindowWorldMorph new open/ nothing happens. Pharo runs but nothing shows up. I expected just to get the SDL window. Can this be done in pharo? Anyone know the technique? -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

[ANN] Freezing Pharo 9 development right now :)
by Esteban Lorenzano May 3, 2021

May 3, 2021

Hi, So, today I was checking how much it is missing for release and what is our status, and I realized if we do not freeze now, we will never release in a reasonable time. So, even if there are a couple of cleanups and that to still do that should happen before, I will declare that Pharo 9.0 enters in freeze Pharo 9.0 right now (and I will sneak the cleanups anyway, but being more careful). What does this means? No more features, just bugfixes No more fixes of things that can wait until Pharo 10 In two weeks I will open the Pharo 10 development branch, up to then, please help fixing what's missing (which is a lot) ! Have a great weekend, cheers! Esteban

Creating a Spec -GTK window without showing the pharo IDE
by kmo May 2, 2021

May 2, 2021

After not lookng at it for I while, I tried the Gtk Spec bindings again on my Xubuntu desktop and - this time - they worked. I was able to open a new window using Spec-Gtk, the latest headless VM and the latest Pharo 9. (Many thanks to all concerned). But I've immediately hit the same issue as I've raised before with SLD support (OSWindow) - it seems impossible to open a Gtk window without the whole Pharo IDE being shown as well. If I run the following command line - ./pharo-ui Pharo.Image eval RunGtk execute I get the Pharo IDE and a GTK window opened If I run ./pharo Pharo.Image eval RunGtk execute I just get the string RunGtk returned. No window opens. I presume this will work some time in the future. Otherwise what's the use of Spec-Gtk (or OSWindow for that matter)? You might as well just use Spec on Morphic. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
