Creating tests for the TinyBlog tutorial

by Michael Burns

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 see that many other packages have *-Tests packages where their tests live. It seems to test OK so itâs not a stopper for me, but I get an error: âTest class not in a package with name ending with â-Testsâ" Iâd like to understand. Iâm running: Pharo8.0.0 build: 1124, commit: 0932da8 On MacOS 11.3.1. M1 MbPro

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.

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).

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

Re: New VM, how do I get it

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.

Sorry yes, I gave you the screen shots without the code.

(Not a File~Reference) In V 8.0 I get an Inspector on a FileReference (/Users/davidpennington/Documents/Pharo/images/Pharo 8.0 - 64bit (stable)).

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.
