Hi Cameron, The main websites explaining things are http://zn.stfx.eu and http://zdc.stfx.eu Please have look there, not forgetting the papers. If you have any more questions after that, please don't hesitate to ask them. Basically, you have to install Zodiac and a plugin to your VM. Regards, Sven PS: In Pharo 2.0 both Zinc and Zodiac are installed and fully operational by default.

secure sockets https in Zinc

by Cameron Sanders

In the method... ZnNetworkingUtils >> streamClassForScheme: scheme scheme = #http ifTrue: [ ^ self socketStreamClass ]. scheme = #https ifTrue: [ ^ self secureSocketStreamClass ifNil: [ self error: 'No secure socket stream class set or available' ] ]. (ZnUnknownScheme scheme: scheme) signal I am getting the error indicating the lack fo secureSocketStreamClass. The initialize and lazy-initialization try to use ZdcSecureSocketStream, but that is not found. I am using Pharo 1.4 (downloaded & configured last summer) with Pier3 loaded, along with Zinc-HTTP (SvenVanCaekenberghe.280), Zinc-Path-HTTPSocket (StephaneDucasse.2) and Zinc-Seaside (SvenVanCaekenberghe.22). I see numerous updates to those and various other new packages. I believe what I have was pulled in by the following last summer: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfPier3'; load. (Smalltalk at: #ConfigurationOfPier3) load. Gofer it squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfPier3AddOns'; load. (Smalltalk at: #ConfigurationOfPier3AddOns) load. - What is the recommended update approach for me, by those *in the know*? Thanks in advance, Cam

Re: [Pharo-users] Gettext in Pharo 1.4

by Chris

Ah now you come to mention it, my changes are actually in the Seaside extensions for it. There were a few deprecated references to MethodReference, which upon ignoring, eventually failed at a theNonMetaClass type call. I converted to RGMethodDefinition and it worked fine. I also did a couple of minor tweaks - one to the RBParseTreeSearcher which was only doing `#string as I had a few translate: messages in my app being passed integers (which had nothing to do with html in fact). Finally it seemed to be outputting method names numerous times. I think due to some perhaps understandable confusion over the way GROrderedMultiMap works. > We're using it in a commercial project on Pharo 1.4 SE, it installed > with no issues :) > > What problem are you having? > > > 2012/11/3 StÃ©phane Ducasse <stephane.ducasse(a)inria.fr > <mailto:stephane.ducasse@inria.fr>> > > I know that hilaire is using it but I do not know who is > maintaining it. > > Stef > > On Nov 2, 2012, at 11:28 PM, Chris wrote: > > > Hi All, > > > > Is anyone maintaining the above package?

We're using it in a commercial project on Pharo 1.4 SE, it installed with no issues :) What problem are you having? 2012/11/3 StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> > I know that hilaire is using it but I do not know who is maintaining it. > > Stef > > On Nov 2, 2012, at 11:28 PM, Chris wrote: > > > Hi All, > > > > Is anyone maintaining the above package?

The proper idiom to use is FileStream readOnlyFileNamed: 'C:\test.txt' do: [ :stream | â¦ ]. or in Pharo 2.0 'C:\test.txt' asFileReference readStreamDo: [ :stream | â¦ ]. 'C:\test.txt' asFileReference writeStreamDo: [ :stream | â¦ ]. HTH, Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

stream usage in workspace

by Ben Coman

I am refereshing my familiarity with streams by looking at PharoByExample1 which says... "You have to remember that each time you open a stream on a ï¬le, you have to close it too." Does that mean if in Workspace I iteratively develop some code to process a stream, so that I am continually running... myStream := FileStream readOnlyFileNamed: 'C:\test.txt. ...so that 'myStream' is overwritten each time such that I lose reference to the previous stream, and I am no longer able to send #close to it, am I creating a memory leak in my image ? My prior assumption has been that once 'myStream' drops the reference drops to the previous stream, garbage collection would take care of 'everything'. cheers -ben

Gettext in Pharo 1.4

by Chris

Hi All, Is anyone maintaining the above package? I had a few issues when trying to use it in Pharo 1.4 Summer but have done a few fixes and it is now working well for me; would like to run them by someone who knows a bit more about it first. Thanks Chris

Acquiring lock, releasing in callback

by Sebastian Nozzi

Hello Dear Pharo users, threads and co. are giving me headaches :-) I wanted to ask for advice... What do I use in Pharo to prevent more than one thread entering a region, but "releasing" the exclusivity in another block/callback? For example, let's suppose there is an hypothetical class "Lock" that does that. lock acquire. longOperation performWhenFinished: [ callback code ... lock release ]. ... rest of the program ... Is there something like that? Or do I have to simulate it with something else? (Semaphore?) I am aware or Monitor/Mutex critical:, but I am not sure I can use it in my case. Thanks in advance, Sebastian
