Cormas Pharo Port v0.2 available

by Serge Stinckwich

Dear all, I made available a new version (v0.2) of Cormas on Pharo. CORMAS is a multi-agent simulation engine that is running on VisualWorks Smalltalk: http://cormas.cirad.fr/indexeng.htm You can download this version by using the last Moose 5.1 image : https://ci.inria.fr/moose/job/moose-5.1/ and doing in a Playground: Gofer new url: 'http://smalltalkhub.com/mc/SergeStinckwich/CORMAS/main'; configurationOf: 'Cormas'; loadStable. At the moment, nothing is working ;-) Almost classes of the original VW version are now in Pharo except some classes like Jun* that will I guess disappear for the new version if we use ROASSAL instead. I will start to clean the code now in order to be able to run as simple model like Fire Automata model All the code is also available on github here: https://github.com/cormas/cormas If some of you want to be added in the CORMAS github org, please tell me: https://github.com/cormas I will feel less alone ;-) You can join the mailing-list to help here: https://groups.google.com/forum/#!forum/cormas-dev Regards, -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://www.doesnotunderstand.org/

Re: [Pharo-users] Proxies: Subclassing nil

Hi if you want to build proxy look at Ghost library from Mariano Martinez I not know right repository.

Sean, I am not an expert in Pharo, but I think you should try subclassing ProtoObject... Joachim Am 31.03.2015 18:51 schrieb "Sean P.

Proxies: Subclassing nil

by Sean P. DeNigris

>From "Design Patterns" pg. 215: You can make[8] generic proxies in Smalltalk by defining classes whose superclass is nil and defining the doesNotUnderstand: method to handle messages. [8] Almost all classes ultimately have Object as their superclass. Hence this is the same as saying "defining a class that doesn't have Object as its superclass." but in Pharo: nil subclass: #MyProxy instanceVariableNames: '' classVariableNames: '' category: '' -> MessageNotUnderstood: receiver of "subclass:instanceVariableNames:classVariableNames:category:" is nil ----- Cheers, Sean -- View this message in context: http://forum.world.st/Proxies-Subclassing-nil-tp4816443.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Issue on enabling developer options in Pharo Launcher

by rohit sharma

hey Damien, before there was a confusion that pharo launcher is not saving proxy settings whenever we close it and we again launch the pharo-launcher we again have to add proxy settings. But the reason for launcher not saving the settings was I was closing the launcher using close button ('X' on top left side), later Nicolai Hess told me that if I use quit button (on bottom right) then launcher will save the proxy settings. greetings rohit On Tue, Mar 31, 2015 at 10:05 PM, Damien Cassou <damien.cassou(a)gmail.com> wrote: > Hi Jigyasa, > > Jigyasa Grover <grover.jigyasa1(a)gmail.com> writes: > > > You mean the update of PharoLauncher ? > > PharoLauncher has had this settings for quite a while now.
