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*

Fame/Famix statically typed
by Nicolas Anquetil 30 Nov '16

30 Nov '16

Why is Fame (and Famix) statically typed? It always seemed strange to me in the Smalltalk context. Do we really use/need this property? (Because sometimes, it really sucks) nicolas -- Nicolas Anquetil -- MCF (HDR) Project-Team RMod

[ANN] Animation package
by Thibault Raffaillac 25 Nov '16

25 Nov '16

Hello, I am happy to release the Animation package at last! http://catalog.pharo.org/catalog/project/Animation This is a general animation system, which can turn any setter message into a smooth transition (provided it has a corresponding getter, and the target value supports + and *Float). Examples: morph position: (100@100 during: 2 seconds easing: #backOut). morph color: (Color red during: 2 seconds). morph title: ('tutututu' during: 2 seconds). I am curious to see if/how it could be used with Roassal/Moose. Please send any (good or bad) feedback you may have while testing it! Cheers, Thibault ps: Thanks to anonymous contributor for the second syntax, it was a lot of fun - and evil laughs :)

smacc updates
by Tudor Girba 24 Nov '16

24 Nov '16

Hi, John and I worked a bit together and updated the following parser: - Delphi - C# (supports version 6.0) - JavaScript As you know, SmaCC is now in the Moose distribution, and it comes with detailed abstract syntax trees. This offers new opportunities for the kinds of analyses we can provide. Cheers, Doru -- www.tudorgirba.com www.feenk.com "There are no old things, there are only old ways of looking at them."

Segfault on Moose 6.1 jobs
by Blondeau Vincent 17 Nov '16

17 Nov '16

Hello, I would like to report some random segfaults happing during the build of the Moose 6.1 image (based on Pharo 6). Please find attached the latest failing stack trace. Here are the 2 jobs that fails: https://ci.inria.fr/moose/job/moose-6.1/345/console https://ci.inria.fr/moose/job/moose-6.1/347/console It seems that they are not failing for the same reason. Maybe because the job is not using the latest VM? : pharo VM version: 5.0 #1 Tue Jun 21 12:37:33 CEST 2016 gcc 4.6.3 [Production Spur ITHB VM] Built from: CoInterpreter VMMaker.oscog-HolgerHansPeterFreyther.1880 uuid: 16138eb3-2390-40f5-a6c8-15f0494936f8 Jun 21 2016 With: StackToRegisterMappingCogit VMMaker.oscog-HolgerHansPeterFreyther.1880 uuid: 16138eb3-2390-40f5-a6c8-15f0494936f8 Jun 21 2016 Revision: https://github.com/pharo-project/pharo-vm.git Commit: 9638b0190a9fc01479bfb752becd96edfd253c8c Date: 2016-06-21 12:29:26 +0200 By: GitHub <noreply(a)github.com> Jenkins build #594 Build host: Linux pharo-linux 3.2.0-31-generic-pae #50-Ubuntu SMP Fri Sep 7 16:39:45 UTC 2012 i686 i686 i386 GNU/Linux plugin path: /builds/workspace/moose-6.1/pharo-vm/ [default: /builds/workspace/moose-6.1/pharo-vm/] Thanks in advance Cheers, Vincent !!!************************************************************************************* "Ce message et les pi?ces jointes sont confidentiels et r?serv?s ? l'usage exclusif de ses destinataires.

[ann] petitparser2
by Tudor Girba 13 Nov '16

13 Nov '16

Hi, I am happy to announce the availability of PetitParser2, a wonderful redesign of the original PetitParser developed by Jan Kurš. https://github.com/kursjan/petitparser2 Highlights: - it introduces the compiler facility that speeds up parsers by a factor of ~2-5x - it introduces the possibility of parsing streams without having them in memory - it comes with a new structure internally that makes it more flexible - it introduces asPParser (not a typo) to be able to have the new version working in parallel with the classic asParser The version is already present in the latest Moose 6.1 in parallel with PetitParser. Also, several of the parsers that are shipping with PetitParser were already copied to PetitParser2 as well. You can find more details here: http://www.humane-assessment.com/blog/introducing-petitparser2/ Some more documentation will follow. I think Jan did a wonderful job and the result is quite exciting. Please take a look and let us know what you think. Cheers, Doru -- www.tudorgirba.com www.feenk.com "What we can governs what we wish."

another question for incremental loading
by stepharo 08 Nov '16

08 Nov '16

Hi doru If I have a model "model1" mse or database it will have internal names/id then I have a delta or even another model and loading it I will need to do a mapping between in memory objects of the model 1 So you propose to remove all the entities related to entities in Model2 from model1 and to load load model2 but to do so you need to know that id:xxx in Model2 corresponds to Class A in Model My impression is that we should really have a uniqueName for any entity.
