Re: pharo 8 - method versions - how to see author/timestamp?

by Esteban Lorenzano

change history for method is already there (as explained in my previous mail). for class and package level is something I always wanted to implement (class level is particularly easy to implement, with tonel format) but I didn't find the time to do it. Volunteers to implement are welcome! ;) Esteban On Feb 5 2021, at 9:16 am, Richard Sargent <richard.sargent(a)gemtalksystems.com> wrote: > Oh, yes/ That is one of the things I most love about ENVY and miss in everything else. > What is the change history of this method, class, package, etc.? > > > > On Thu, Feb 4, 2021 at 10:09 PM Kasper Osterbye <kasper.osterbye(a)gmail.com (mailto:kasper.osterbye@gmail.com)> wrote: > > I went in and updated the corresponding github issue (https://github.com/pharo-project/pharo/issues/7283) The tool is really useful, and it would be nice to have the author and timestamp in place again. > > > > > > > >

Re: pharo 8 - method versions - how to see author/timestamp?

by Esteban Lorenzano

Hi all, While the timestamp for the in-image change is, indeed, missing and needs to be fixed, I want to point that we are abandoning the in-image author tracking by method and replacing it with the git history (which wive you also authorship and timestamp by commit). This method commit history is already there (since Pharo 8) and can be queried with the "history" button in the minitoolbar of calypso, same place where you have the access to the version browser. Yes, it is not the same, but it fulfills correctly (and improves it, since it gives you the whole method history, not just what you have in image) the old version functionality, which however will remain as a track of in-image changes, but without the author (since is not needed). Even more, all the Author infrastructure is target for removal in next versions of Pharo (just not right now :P) cheers!

Oh, yes/ That is one of the things I most love about ENVY and miss in everything else. What is the change history of this method, class, package, etc.?

Migrating RBLintRules to Renraku rules

by Sebastian Jordan

Hi, I have found out that RBLintRule will be deprecated. I have a code that uses RBLintRule and I need to migrate it to Renraku Rules. I have a code that applies an RB transformation rule to a set of packages. Currently, I obtain the changes of the transformation with the following code: (RBSmalllintChecker runRule: anRBTransformationRule onEnvironment: env) builder Can someone please explain me how to do this but using ReNodeRewriteRule and ReSmalllintChecker? Thank you in advance, Sebastian

(sorry for redundancies) Hello, Bonjour, Hola, We are looking for a Master internship to work on Cormas, a simulation platform (https://github.com/cormas/cormas , or see here for our presentation at ESUG: https://hackmd.iscpif.fr/GGwvzBFqRASE5zCzlRwArQ?view) Nous recherchons un stagiaire de Master pour travailler sur Cormas, une plateforme de simulation (https://github.com/cormas/cormas , cf. notre prÃ©sentation Ã ESUG: https://hackmd.iscpif.fr/GGwvzBFqRASE5zCzlRwArQ?view) Estamos buscando un estudiante de MaestrÃa para trabajar en Cormas. Voici l'annonce en franÃ§ais (in English below) : https://www.hdigitag.fr/fr/les-offres-de-stage-digitag/ *Simulation participative de la gestion des ressources renouvelables dans des environnements hybrides* *Mots-clÃ©*: Simulation participative, Computer Vision , Smalltalk, Cormas * *DurÃ©e souhaitÃ©e du stageÂ (nombre de mois):*8 * *Date de dÃ©but du stage*: 1/02/2021 * *UnitÃ© de recherche*: Green, Cirad * *Contact*: Bommel Pierre : bommel(a)cirad.fr * *#DigitAg*: Axe 2 : Innovations en agriculture numÃ©rique, Axe 6 : ModÃ©lisation et simulation (systÃ¨mes de production agricole) / Challenge 1 :Â Le challenge agroÃ©cologique, Challenge 2 :Â Le phÃ©notypage rapide, Challenge 6 :Â La gestion des territoires agricoles, Challenge 7 :Â IntÃ©gration de lâagriculture dans les chaÃ®nes de valeur, Challenge 8 : DÃ©veloppement agricole au Sud Lâambition dâÃ©liminer les interfaces physiques qui permettent lâinteraction avec les machines est une idÃ©e ancienne dans le monde de lâinformatique qui a pris plusieurs directions. La plus emblÃ©matique pour le grand public a Ã©mergÃ© en 2005 sous le nom de âprojet Natalâ repris et dÃ©mocratisÃ© par Microsoft dans sa derniÃ¨re version baptisÃ©e âAzure Kinectâ (2019). Ce capteur dÃ©tecte les mouvements et les objets dans le champ de vision de lâutilisateur pour produire des rÃ©sultats dans un logiciel. Il a Ã©tÃ© abondamment dÃ©tournÃ© et enrichi depuis ses dÃ©buts grand public pour permettre de nouvelles maniÃ¨res dâinteragir avec les machines. Par ailleurs, le groupe de chercheurs Ã lâorigine de la crÃ©ation dâune plateforme de modÃ©lisation Ã base dâagents baptisÃ©e Cormas [1] fait actuellement face Ã des besoins accrus dâinteractivitÃ©s dans les simulations participatives. BasÃ©e sur le langage Smalltalk, Cormas est dÃ©veloppÃ©e depuis la fin des annÃ©es 1990 par une Ã©quipe fortement interdisciplinaire. Au-delÃ des usages traditionnels de la modÃ©lisation agents, Cormas se dÃ©marque des autres plateformes par des processus originaux de modÃ©lisation : lâapproche ComMod (pour Companion Modeling : modÃ©lisation dâaccompagnement [2]), qui vise Ã proposer des outils permettant de participer activement Ã la conception dâun modÃ¨le, mais aussi de sâimmerger dans des situations de jeux interactifs. Le jeu (de plateau ou informatisÃ©) sert alors de support pour Ã©changer sur une situation vÃ©cue. En 2012, pour la premiÃ¨re fois, lâÃ©quipe utilisait un video-projecteur Ã ultra-courte focale pour projeter sur une table un plateau de jeu. Ce simple changement a induit des comportements radicalement diffÃ©rents leur permettant une interaction beaucoup plus naturelle avec les simulations informatisÃ©es. En outre, la configuration spatiale des acteurs favorise les interactions sociales. Mais jusquâÃ aujourdâhui, la saisie manuelle par lâanimateur des dÃ©cisions prises par les joueurs reste nÃ©cessaire ce qui rÃ©duit la fluiditÃ© et la spontanÃ©itÃ© des interactions. LâÃ©quipe en charge du dÃ©veloppement de Cormas souhaite investiguer les possibilitÃ©s offertes par les nouvelles applications liÃ©es Ã la dÃ©tection dâobjets et de mouvements en portant un prototype de simulation participative dans le champ de la simulation hybride entre modÃ¨le informatique et jeu physique. Ce travail de preuve de concept appliquÃ© au modÃ¨le ReHab (modÃ¨le Ã©cole de ComMod) nÃ©cessitera de mettre au point des mÃ©thodes de dÃ©tection fiables dâobjets physiques pour Ãªtre intÃ©grÃ©es dans le calcul du nouvel Ã©tat simulÃ©. Aujourdâhui, Cormas sâappuie sur Pharo (Smalltalk open-source). Cette solution est dÃ©veloppÃ©e par lâINRIA et par un consortium de chercheurs et dâindustriels. La communautÃ© dynamique propose un ensemble de packages permettant de mutualiser le dÃ©veloppement de fonctionnalitÃ©s qui pourraient Ãªtre mobilisÃ©es pour proposer un prototype pour des simulation participative et la dÃ©tection dâobjets *English* : https://www.hdigitag.fr/en/digitag-master2-internship-offers/ *Participatory simulation of renewable resource management in hybrid environments* * *Keywords*: Participatory simulation, Computer Vision , Smalltalk, Cormas * *Duration*: 8 months * *Desired start date*: 1/02/2021 * *Research Unit*: Green, Cirad * *Contact*: Bommel Pierre â bommel(a)cirad.fr * *#DigitAg*: Axe 2,Axe 6 â Challenge 1,Challenge 2 ,Challenge 6 ,Challenge 7, Challenge 8 The ambition to remove the physical interfaces that allow interactions with computers is an old idea in the IT world that took several directions. The most emblematic one for the general public emerged in 2005 under the name of âProject Natalâ taken up and democratized by Microsoft in its latest version called âAzure Kinectâ (2019). This sensor detects movements and objects in the userâs field of vision to produce results in softwares.Â It has been abundantly diverted and enriched since its beginnings for the general public to allow new ways of interacting with computers. In addition, the group of researchers behind the development of an agent-based modeling platform called Cormas [1] is currently facing increased needs for interactivity in participatory simulations. Based on the Smalltalk language, Cormas has been developed since the late 1990s by a highly interdisciplinary team. Beyond the traditional uses of agent modeling, Cormas differs from other platforms by innovative modeling processes: the ComMod approach (Companion Modeling [2]), which aims to provide tools to actively participate in the design of a model, but also to immerse oneself in interactive game situations.Â The game (board or computer game) is then used as a support to exchange on a real-life situation. In 2012, for the first time, the team used an ultra-short focal projector to project a game board on a table. This simple change induced radically different behaviors of the actors allowing them to interact more naturally with computer simulations. In addition, the spatial configuration of the actors favors social interactions.Â But until today, manual input by the facilitator of the decisions taken by the players remains necessary, which reduces the fluidity and spontaneity of interactions. The team in charge of Cormasâ development wishes to investigate the possibilities offered by new opportunities related to the detection of objects and movements by bringing a prototype of participatory simulation in the field of hybrid simulation between computer model and physical game.This proof of concept work applied to the ReHab model (ComModâs school model) will require the development of reliable detection methods for physical objects to be integrated into the calculation of the new simulated state. Today, Cormas relies on Pharo (an open-source Smalltalk).Â This solution is implemented by INRIA and a consortium of researchers and industrialists. The dynamic community proposes a set of packages allowing to mutualize the development of functionalities that could be mobilized to propose a prototype for participative simulation and object detection
