[ANN] SortFunctions (Multiple criteria sorting)

by Esteban A. Maringolo

After the discussion about multiple sort criteria [1] I decided to make some modifications I was needing, and also repackage the initial port Nicolas Cellier did. The result is the transformation of Nicolas' TAG-SortFunctions [2] "experiment" to a first class project plainly named 'SortFunctions' available at: http://smalltalkhub.com/#!/~emaringolo/SortFunctions/ Nicolas said: "Since I got absolutely zero feedback after a long thread, I assumed it was not interesting anybody... But my personal opinion differs: this should be included in each and every Smalltalk." I sorry for not replying before, I also think this kind of features should be easily discoverable in a default image, and that's why I built a Metacello config to be included, maybe, in the MetaRepo. Credits were preserved in the STHub project site both for Travis and Nicolas. Best regards, Esteban A. Maringolo [1] http://forum.world.st/Has-someone-ever-built-a-sort-block-generator-tp47712… [2] I guess TAG is for Travis A. Griggs

Re: [Pharo-users] Zoomable & Infinitely scrollable PasteupMorph

by Alexandre Bergel

Here is an example: -=-=-=-=-=-=-=-=-=-=-=-= | v | v := RTView new. v @ RTZoomableView. v add: (RTLabel new elementOn: 'Scroll your mouse wheel while hovering cursor over the view to zoom it'). v -=-=-=-=-=-=-=-=-=-=-=-= https://www.facebook.com/video.php?v=700319393387994&set=vb.340543479365589… Zooming is not infinite here. There is nothing that prevent us from doing it. It is just we have not faced any need. What would be a simple and compelling example of infinite zooming? This would be fun to implement. Each element should have a depth right? And zooming is actually moving the camera in and out? Cheers, Alexandre On Sep 16, 2014, at 12:13 PM, Sean P.

Re: [Pharo-users] Zoomable & Infinitely scrollable PasteupMorph

by Alexandre Bergel

In the word âsubmorphâ there are two important parts. âsubâ and âmorphâ. Roassal support subelements, but only one morph is around, the trachel morph that contains all the drawing. Why staying in Morphic? Morphic does not scale well, does not have layout, and morphs are hardly composable with other morphs :-) Cheers, Alexandre On Sep 16, 2014, at 7:13 AM, Sean P.

[ANN] Test Coverage with Hapao

by Alexandre Bergel

Dear all, We are happy to release Hapao2 for Pharo. Ricard Jacas and Alejandro Infante put quite some work on Spy2 (an Ã¼ber cool profiling framework for Pharo) and Hapao2. Hapao2 is about assessing the test coverage of your code and is a major revamp of Hapao1, which was presented a couple of years ago by Vanessa. Hapao2 does not only list covered and uncovered methods, as most test coverage tool on Earth will do. Hapao gives a great visualization to easily navigate in your code, assess its complexity, and give you a great visual output telling its coverage. You need Roassal in your image: Gofer new smalltalkhubUser: 'ObjectProfile' project: 'Roassal2'; package: 'ConfigurationOfRoassal2'; load. (Smalltalk at: #ConfigurationOfRoassal2) load and you need S2py: MCHttpRepository location: 'http://smalltalkhub.com/mc/ObjectProfile/S2py/main' user: '' password: '' New entries will appear in the world menu: You can run the test coverage on : - the class classes you have modified, - on a particular - on a particular class category - on the last class categories you have modified - on the last packages you have modified Here is a portion of a large coverage: A technical description of Hapao may be found on http://bergel.eu/download/papers/Berg12c-HapaoSCP.pdf We are daily using Hapao to help us understand our tests.
