Roassal: Adjusting to fixed canvas size
by Hernán Morales Durand 30 Dec '18

30 Dec '18

Hi guys, Using Pharo 6.1/Win here. Is there any way to adjust a RTView canvas to a fixed size, say 620 x 744 px, before the elements gets added into the view? This is what I've tried so far: 1) Empty canvas manually set to 620 x 744 px produces 1x1 image: | view | view := RTView new setCanvas: (TRCanvas new extent: 620 @ 744; yourself); yourself. (RTCanvasExporter canvas: view canvas) format: #png; fileName: 'test_empty.png'; export. 2) Non-empty canvas manually set to 620 x 744 px produces 25x15 image: | view elems | view := RTView new setCanvas: (TRCanvas new extent: 620 @ 744; yourself); yourself. elems := (RTBox new color: Color blue) elementsOn: (1 to: 5). view addAll: elems. RTGridLayout on: view elements. (RTCanvasExporter canvas: view canvas) format: #png; fileName: 'test_5elems.png'; export. 3) Idem 2) adding #scale: 10 -> 250x150px ... #scale: 24.8 -> 620 px | view elems | view := RTView new setCanvas: (TRCanvas new extent: 620 @ 744; yourself); yourself. elems := (RTBox new color: Color blue) elementsOn: (1 to: 5). view addAll: elems. RTGridLayout on: view elements. (RTCanvasExporter canvas: view canvas) format: #png; scale: 12.4; fileName: 'test_5elems_scaled.png'; export. 4) Adding #oversizedBy: to 3) finally makes the trick: | view elems | view := RTView new setCanvas: (TRCanvas new extent: 620 @ 744; yourself); yourself. elems := (RTBox new color: Color blue) elementsOn: (1 to: 5). view addAll: elems. RTGridLayout on: view elements. (RTCanvasExporter canvas: view canvas) format: #png; scale: 24.8; oversizedBy: 0 @ 15; fileName: 'test_5elems_scale2_osized.png'; export. - So setting manually canvas extent doesn't have any effect? - Any way also to set a fixed margin or padding size (distance between image element and border)? Cheers, Hernán

Help: how to follow Parameters
by Erik Stel 14 Dec '18

14 Dec '18

Through a jdt2famix parsed model of an application I'm trying to follow the usage of a (FAMIX)Parameter. How can this be done? >From a method parameter I can access its enclosing method and from there on find invocations within that method for example. The problem is that there does not seem to be a direct way to retrieve the fact that a parameter is part of a method invocation (both direct or as part of an expression). It seems I have to parse a piece of the source code (the invocation signature to be precise). This does not feel okay. Can anyone give some pointers on how to find parameter usage without resorting to parsing the source code (if such a solution exists)? (Googling didn't help so far, or I'm not using the right search parameters ;-) Example Java source code, for which I want to follow the 'x' parameter: void startPoint(String x, int y) { // Here is first 'simple' parameter usage this.doSomething(x, y); // Here parameter is part of an expression this.that.doAnother("[" + x + "]"); // Parameter is part of expression again (twice) this.doLast(x.substring(0, y) + x.substring(y + 8)); } Cheers, Erik -- Sent from: http://forum.world.st/Moose-f1310756.html

Users of Phexample are trapped
by Stéphane Ducasse 04 Dec '18

04 Dec '18

We should pay attention to super vicious dependencies. For example ConfigurationOfPhexample dependent on a new version of StateSpecs. baseline21: spec <version: '2.1-baseline'> spec for: #'common' do: [ spec blessing: #'baseline'. spec repository: 'http://www.smalltalkhub.com/mc/Phexample/Phexample/main'. spec baseline: 'StateSpecs' with: [ spec repository: 'github://dionisiydk/StateSpecs:v2.4.x’]. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ spec package: 'Phexample' ]. Since this baseline is referring to github, it means that old users of Phexample cannot load anymore their code. This is funny because they cannot load their code to be able to fix it to load in recent pharo version. So Alain cannot migrate his project because petitparser use Phexample.

MetricNormaliser on edges
by Nicolas Anquetil 06 Nov '18

06 Nov '18

A question on normalizing edges in RTMondrian: I want to show the "strength" of the edges, computed according to some metric. How can I normalize for example the color of the edge to reflect this "strength" ? Or maybe, normalize the "boldness" of the edge ? nicolas -- Nicolas Anquetil RMod team -- Inria Lille
