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.

Hi Smalltalk enthusiasts! Since Tim and I were already asked for a second CampSmalltalk this spring we decided hold another camp in Nanaimo at the end of April.

We have the Space all weekend long and do not need to leave the place this time! If you are interested in ... any kind of ScratchOnPI projects ... combining your Smalltalk project with any other peripheral device ... would like to try a different Smalltalk out ... just want to chat and meet old and new friends ....then this should be the perfect weekend to do this and come over to Makerspace in Nanaimo.

The code to do that is in gitfiletree in fact ;) There is also a filesystem-like layer for archives somewhere inside Pharo, but, I do believe it doesn't work (I'm sure I tried it... and if I'm not using it, there is a good reason).

VOSS seems quite an interesting and useful technology. Is know for sure that it could be ported without disturbing Pharo opensourceness / freeness? Is anyone doing work to port it?

Re: [Pharo-users] Gitfiletree unstable on Windows

Hi Jan, there is a chance the problem is in the interface GitFileTree uses to call git on windows.
