Pharo developers you can subscribe to Pharo-Users too ; )

by Mariano Martinez Peck

Hi everybody. We have two mailing list as you may know: one for pharo developers or people very interested in Pharo and its internal details. This mailing list is pharo-project(a)lists.gforge.inria.fr It is high traffic and there are a lot of people that cannot follow. Then we have the Pharo-User mailing list for those that just want to use Pharo and don't care about their internals. This mailing list has less traffic. This mailing list is pharo-users(a)lists.gforge.inria.fr The problem is that there is people that are subscribed to pharo-project(a)lists.gforge.inria.fr but not to pharo-users. In this last mailing list, usually new comers ask questions. It would be great that all the people that is already subscribed to pharo-project(a)lists.gforge.inria.frand have time to follow that mailing list, to subscribe also to Pharo-Users. Sometimes I am obligued to tell new comers "ask in pharo-project(a)lists.gforge.inria.fr as not all the people is subscribed there" ... and thus, the Pharo-Users becomes useless. Thanks Mariano

Re: [Pharo-users] [Pharo-project] RB AST serialization

by Johan Fabry

(To pharo-users as I am not on pharo-project, and I think neither is Daniel) Yes we have been considering various strategies to get it as compact as possible and considering cputime/memory trade-offs (and making it possible to select compression strategies). But want to get it to work first. These undocumented nodes are the next hurdle: we need some info on RBPragmaNode, RBArrayNode, RBLiteralArrayNode so that Daniel can write the serializer for them.

As it says the welcome workspace of Pharo, you can install O2 like this: Gofer new squeaksource: 'MetacelloRepository'; package:'ConfigurationOfO2'; load. ((Smalltalk at: #ConfigurationOfO2) project version: '1.2') load: 'Dev'. That will install the O2 browser.You will notice this is a different browser. There are narrows pointing to left and right that may be something similar to what you want. Anyway, did you try WorkingSet ? Read this link: http://forum.world.st/ANN-WorkingSet-td1296111.html#a1296111 Cheers Mariano On Mon, Apr 26, 2010 at 4:53 PM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr > wrote: > Hi alex > > Some browsers like the O2 browser supported it but it is a bit ad-hoc and > slow.

Re: [Pharo-users] XmlRpcClient for smalltalk ?

Hi. This is what I know: http://www.squeaksource.com/XMLRPC.html and http://www.mars.dti.ne.jp/~umejava/smalltalk/soapOpera/index.html Finally, maybe it is not completely related to XMLRPC but this may be of help: http://pharocasts.blogspot.com/2010/02/rest-xml-parsing-and-photos.html Cheers Mariano On Tue, Apr 27, 2010 at 8:52 AM, tommy koorevaar <tommy.koorevaar(a)gmail.com>wrote: > Hello everyone, > > I'm a French student and I'm working on a project in which I have to send > XmlRpc request with smalltalk. > > Does anyone know if there is anything already implemented I could use ? > > Thank you very much, > Tom > > _______________________________________________ > Pharo-users mailing list > Pharo-users(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-users > >

XmlRpcClient for smalltalk ?

by tommy koorevaar

Hello everyone, I'm a French student and I'm working on a project in which I have to send XmlRpc request with smalltalk. Does anyone know if there is anything already implemented I could use ? Thank you very much, Tom

Hi alex Some browsers like the O2 browser supported it but it is a bit ad-hoc and slow. You can try by loading ConfigurationOfO2 from the MetacelloRepository repository.

Hi, when using a SystemBrowser, can there be a navigation history? To explain what iÂ mean, here is an example. WhenÂ you search : Â Rectangle >> flipBy: direction centerAt: aPoint ; Point >> rect: aPointÂ ; Rectangle >> origin: originPoint corner: cornerPoint ; Â Â .. and then want to go back to : Â Rectangle >> flipBy: direction centerAt: aPoint Â , is there some tool allowing to step back ?

Very nice. I like the casts being faster :). In a few places (e.g., where you have to read text from the help system to be able to follow) it was slightly too fast, though.
