Hi, I updated the book with the code that works with the latest Glamour. Also, if you want to see examples, they already exist in the image. For the GLMMorphPresentation, you have an example here: GLMBasicExamples>>morphIcons For further clarifications, you better join the Moose mailing list: moose-dev(a)iam.unibe.ch https://www.iam.unibe.ch/mailman/listinfo/moose-dev Cheers, Doru On Mar 28, 2013, at 3:25 PM, Jesus NuÃ±ez <poissonbreaker(a)gmail.com> wrote: > Hello everyone, > > Does anybody have the full definition of GLMMorphPresentation such > that is usable with Glamour, especifically with the > GLMCompositePresentation?.

Hi HernÃ¡n I once did some code statistics for our web frameworks, by counting: - Nr of packages, categories, classes, methods - lines of code - Avg methods/class - Avg lines/method - Nr of test methods - Avg tests/class - % of commented methods - % of commented classes Then three graphs were drawn: - Methods in classes - Class inheritance depth - Lines in methods Results can be seen here: https://docs.google.com/spreadsheet/ccc?key=0Atnb1W9vuq9ndG4wbUpxNXpKQnFZRl… The code measuring all above is here: http://www.squeaksource.com/WebCodeStats.html Hope this helps Janko Dne 31. 03. 2013 09:23, piÅ¡e HernÃ¡n Morales Durand: > Hi there, > Guys, what are you using to measure logical lines of code (LOC) in Pharo? > Given I am measuring a script, is there any other software measure you > may recommend? > Cheers, > > HernÃ¡n > -- Janko MivÅ¡ek Aida/Web Smalltalk Web Application Server http://www.aidaweb.si

This will automatically provide a great opening for Pharo to work with the underlying OpenCL libraries for effective use of multi CPU cores and across GPU's.

Hello alain > I am developing MathsOntologie under Pharo 2.0 beta, and testing it under Pharo 1.4; when the test is OK I distribute MathsOntologie with Pharo 1.4 as "all in one". Don't know if it is the best way to do but I became used to itâ¦ Why not under 20? I would stick with the latest version since 1.4 is one year old. > By the way, I am ashamed that I never made a unit testâ¦ Just start :) this is easy. > Also, when I wanted to translate in French the method "add: anObject times: aNumber" to a Collection, I found that it didn't work, what did not work? > so I created it with something like > > Collection>add: anObject times: aNumber > aNumber timesRepeat: [self add: anObject]. may be to be consistent with add: > Collection>add: anObject times: aNumber > aNumber timesRepeat: [self add: anObject]. ^ anObject > > > I don't know if it was intended or a bug, and and did not find it very difficult to create this method but I asked myself why this method did not work. And I could not test it afterwards because I could not update Pharo 2.0 beta (conflicts between consecutive updates); I have to download Pharo 2.0 and transfer MathsOntologie inside the new version; I just did not have the timeâ¦ What you should always make sure is that you can rebuild your system everyday.
