Hi Ben, Thanks for all the feedback, I am happy that NeoCSV is useful for you. Regarding your problem, I tried a related but different solution. When a user specifies that a field should be an integer or a float, IMO you want an error in case the input cannot be parsed. But indeed, empty/missing fields are an exception. I implemented the default option to skip further processing empty fields. No configuration needed. Please have a look and tell me if that solves your use case.

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?
