[Glamour] default selection in ListPresentation
by Cyrille Delaunay 24 Mar '18

24 Mar '18

Hello, Is there a way to set a default selection to a list presentation? so that when I open the browser, the morphic list has already a value selected. I tried that: |tmpBrowser| tmpBrowser := GLMTabulator new. tmpBrowser row: #list. tmpBrowser transmit to: #list; andShow: [:a | a list display: [:input | input]; selection: #a; yourself ]. tmpBrowser openOn: #( b c d v a d f r). but the list still open with nothing selected

[ann] gtspotter: a moldable interface for spotting objects
by Tudor Girba 23 Sep '17

23 Sep '17

Hi, Alex Syrel, Andrei Chis and I are happy to announce a new addition to the Glamorous Toolkit: GTSpotter, a novel interface for spotting objects. GTSpotter has two goals: - Provide a uniform yet moldable interface that can work on any object, and - Handle searching through arbitrary levels of object nesting. We think this will have a significant impact on the development workflow in Pharo. Here is a couple of screenshots: [image: Inline image 2] [image: Inline image 1] [image: Inline image 3] A trailer is available here: https://www.youtube.com/watch?v=PhSmjR3NOlU A detailed description is available here: http://www.humane-assessment.com/blog/introducing-gtspotter It works already in Pharo 3.0 and can be played with by following the instructions from: http://gt.moosetechnology.org Please let us know what you think. Enjoy, The Glamorous Team

A quick analyzis of the usage of instance variables in Moose
by Guillaume Larcheveque 14 Mar '17

14 Mar '17

Hi Moose users, as you may know, at Synectique we experiment lots of issues about memory usage. That's why i had a look at the number of unused instance variables in one of our system loaded with a big model from one of our main customer. Total instance variables: 26.852.653 Used instance variables: 17.393.938 Empty collections: 5.023.508 Recoverable instance variables: 14.482.223 The recoverable instance variables are those with nil or an empty collection (or MultiValueLink) As you can see, we can save a lot of memory :-) Here is my (dirty) code to get that: countUsedInstanceVariableInForSubInstances: aClass | usedInstNbr instNbr emptyCollNbr | usedInstNbr := 0. instNbr := 0. emptyCollNbr := 0. aClass allSubInstancesDo: [ :anEntity | instNbr := instNbr + anEntity class allInstVarNames size. anEntity class allInstVarNames doWithIndex: [ :e :i | (anEntity instVarAt: i) ifNotNil: [ :content | ([ content isEmpty. emptyCollNbr := emptyCollNbr + 1. false ] on: MessageNotUnderstood do: [ false ]) ifFalse: [ usedInstNbr := usedInstNbr + 1 ] ] ] ]. ^ {('Used instance variables' -> usedInstNbr). ('empty collections' -> emptyCollNbr). ('Recoverable instance variables' -> (instNbr - (usedInstNbr - emptyCollNbr))). ('Total instance variables' -> instNbr)} -- *Guillaume Larcheveque*

Roassal examples browser - too many items
by Ben Coman 27 Feb '17

27 Feb '17

Just some quick feedback... in the "Moose Suite 6.0 (beta)" image from PharoLauncher I opened World > Roassal > Roasasal Examples Nice interface, but for the category "Grapher - Overall" I find there are too many items, such that even the text labels are too small to read. It might be better to split this out to a few more categories. cheers -ben

ElasticBoxZoom
by Ben Coman 27 Feb '17

27 Feb '17

I loaded Roassal into Pharo 60411 and tried #exampleElasticBoxZoom. I select a major portion of the graph, but it zooms down onto one of the tiny axis tick-marks. Is there an issue tracker that is a better place to report this? cheers -ben P.S. I was trying to run Moose 6.0 (beta) from Pharo Launcher on top of a recent VM Feb 22 2017. It was locking up and crashing and I wasn't sure how the versions aligned, so switching to loading Roassal from catalog into 60411 has been running fine.

GTInspector duplicates overriden extensions
by Peter Uhnak 25 Feb '17

25 Feb '17

Hi, when I override a method with a GTInspector (because I need to change it), then inspector contains the extension twice. It seems Inspector scans the whole hierarchy of the inspected object for methods, but doesn't deduplicate them. Peter

CK metrics from Moose? (was Re: Publications of projects using Moose?)
by Cris Fuhrman 24 Feb '17

24 Feb '17

Hello! I'm wondering if it's in the scope of Moose to get to the standard CK metrics for a model? It seems it's been done experimentally ( https://pdfs.semanticscholar.org/0eb2/14ec7c6288dc13564580beafc2609b09118b.…) and I also found the momfe paper from 2002 ( http://scg.unibe.ch/archive/projects/Bute02a.pdf) but appeared not to have all the CK metrics. I also found the right-click on a Moose Model -> Export -> Export model to MSE, but there was nothing that looked like standard CK metrics in the exported file. We are particularly trying to generate CBO (for a research comparison) for a few classes and would like to be able to do all our work in Moose if possible (especially with the visualizations in a RTView).

Position of #numberOfLinesOfCode in hierarchy
by Cyril Ferlicot D. 24 Feb '17

24 Feb '17

Hello everyone, I found something I find odd today. The method #numberOfLinesOfCodes is defined on the Behavioral entities. I would have expected it on the Sourced entities because if an entity has sources it should have a number of lines of code. What do you think? -- Cyril Ferlicot http://www.synectique.eu 2 rue Jacques Prévert 01, 59650 Villeneuve d'ascq France

How ready is Bloc for a simple use-case?
by Peter Uhnak 23 Feb '17

23 Feb '17

Hi, I wanted to ask about Bloc: 1) how stable is the API? e.g. if some overhaul changes to unify/whatever are planned 2) I saw in the techtalk that you can align elements (to center, bottom, ...), however is that possible with lines? Lines have to rotate, morph shape, etc. 3) Are non-straight lines possible? (e.g. bezier, arc) The idea for me is to make a simple mindmap - elements with some text, icons, math symbols inside - connectors (non-straight lines) between elements To me (apart from the lines) it seems like it should be already doable. Also either my (Morphic) Pharo is really slow, or Bloc (in the video) is superfast (everything is happening instantly). Thanks, Peter
