Roassal: Locate a legend text below a line
by Hernán Morales Durand 21 Feb '17

21 Feb '17

Hi everybody, I have this complicated code to draw a line with separators at both ends, I try to put the legend text with #below but nothing is changed : | view e1 e2 l1 label | view := RTView new. label := RTLabeled new color: Color black; below; text: 'Class IIa'; yourself. e1 := RTBox new element color: Color black; height: 10; width: 1; yourself. e2 := RTBox new element color: Color black; height: 10; width: 1; yourself. l1 := RTStyledMultiLine new color: Color black; solidLine; edgeFrom: e1 to: e2. view addAll: (Array with: e1 with: e2 with: l1). l1 @ label. RTHorizontalLineLayout new on: view elements. view elements pairsDo: [ :a :b | b translateBy: 100 @ 0 ]. ^ view Any suggestion? Hernán

Hi, Thank you Nicolas and Anne for the hints/links @Alex Yes, genetic algorithms are “abstract” algorithms. I am actually talking about analysing the code of the frameworks for developing different genetic algorithms to solve all kinds of optimisation problems (knapsack, Traveling Salesman Problem but also “real life" problems : image processing, and many artificial intelligence problems) There are many GA frameworks. Some popular ones are : ECJ (https://cs.gmu.edu/~eclab/projects/ecj/), OpenBeagle (http://vision.gel.ulaval.ca/~parizeau/Publications/beagle-gecco.pdf), WatchMaker (http://watchmaker.uncommons.org/), HeuristicLab (http://dev.heuristiclab.com/)… Abdelghani Message: 4 Date: Thu, 16 Feb 2017 11:02:44 -0300 From: Alexandre Bergel <alexandre.bergel(a)me.com> To: Moose-related development <moose-dev(a)list.inf.unibe.ch> Subject: [Moose-dev] Re: software reingineering guidelines Message-ID: <9D54173C-8CD7-4873-A5F9-AC0EF570EAB2(a)me.com> Content-Type: text/plain; charset=utf-8 Ah ah! Sorry, I read too fast! But it is not clear what are you referring to when you mention “generic algorithm”? Can you give an example? Alexandre

Hi guys, I downloaded Moose from http://moosetechnology.org/res/download/moose_suite_6_0-linux.zip My system info: $ uname -a Linux mvs-virtual-machine 3.19.0-69-generic #77~14.04.1-Ubuntu SMP Tue Aug 30 01:29:21 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux $ lsb_release -a No LSB modules are available.

Roassal: Why the grey outline?
by Hernán Morales Durand 18 Feb '17

18 Feb '17

The attached capture is the one implemented by the method #exampledoubleCurves. If you zoom the image you will notice the grey edge of each green and blue line. The same happens in #exampleVerticalAndHorizontalLines Is there a way to remove it the grey around each line? Cheers, Hernán

AthensCairoCanvas>>setPaint: receiving a "Color transparent"
by Hernán Morales Durand 17 Feb '17

17 Feb '17

I am using stable branch of Roassal2 in Pharo 5 and Win 8.1 to draw a figure for a paper (but the problem is the same loading the latest versions SmalltalkHub). When trying to open a grapher, I get a yellow-cross red morph window inside #setPaint: . The transparent color passed as argument came from AthensCairoSurface>>clear The same figure used to open without problems some months ago. All the Roassal examples open without problems. That's why here is the link to the fuel out stack with the halt previous to the crash : https://dl.dropboxusercontent.com/u/103833630/Debugger-Stack-AthensCairoCan… Is this a well-known bug? Any suggestion? Cheers, Hernán

Hi Alex, The idea is not to use genetic algorithms to improve software quality. Rather, to use Moose to enhance the design of existing frameworks for genetic algorithms. I have attached a brief description of the project to this email. It is in french but this is not a problem for you I think :) > On 15 Feb 2017, at 12:00, moose-dev-request(a)list.inf.unibe.ch wrote: > > Message: 2 > Date: Tue, 14 Feb 2017 08:13:22 -0300 > From: Alexandre Bergel <alexandre.bergel(a)me.com <mailto:alexandre.bergel@me.com>> > To: Moose-related development <moose-dev(a)list.inf.unibe.ch <mailto:moose-dev@list.inf.unibe.ch>> > Subject: [Moose-dev] Re: software reingineering guidelines > Message-ID: <6DD0680F-39CB-4E2D-8E42-9ECFF1D77542(a)me.com <mailto:6DD0680F-39CB-4E2D-8E42-9ECFF1D77542@me.com>> > Content-Type: text/plain; charset=utf-8 > > hi Abdelghani, > > How do you plan to use genetic algorithms ?

Book, Working Effectively with Legacy Code

Interesting to see this is the top mentioned book on stackoverflow. I wonder if Moose can facilitate any of its contained topics and maybe leverage its popularity. </randomThoughForTheDay> cheers -ben

software reingineering guidelines
by Abdelghani Alidra 14 Feb '17

14 Feb '17

Hi, I am about to propose an end of studies’ project for professional Master students consisting in analysing some existing genetic algorithms frameworks with Moose. The idea is that the students 1) control the principals of code quality, architectural issues and refactoring 2) evaluate the ease of adaptation of the existing frameworks. So my questions are : 1) has anybody experienced to work with Master students in using Moose for such purposes (analysis, reengineering, refactoring)? 2) is there a document that describes the guidelines for software code analysis, reengineering, refactoring (with Moose)? Thank you in advance Abdelghani

Hi all, I am wondering how in CodeCity I can zoom using the mouse wheel instead of the keys w and s in the keyboard. I am using Moose 5.1 for Windows. Best regards, Leonel Merino PhD student University of Bern +41 78 405 43 38 merino(a)inf.unibe.ch
