Is that just me, or... The pharo tutorials are read-only in 30782, and therefore I can't open a menu and 'do it (d)' ? Thierry -- Thierry Goubier CEA list Laboratoire des Fondations des SystÃ¨mes Temps RÃ©el EmbarquÃ©s 91191 Gif sur Yvette Cedex France Phone/Fax: +33 (0) 1 69 08 32 92 / 83 95

Unexpected stream version 19 where it should be 193." It says that in the current stream the version is 19 but the code now expects 193. So you should load Fuel 1.9 to materialize those files.

FLMaterializer Materialization error

by Lorenzo Baracchi

Hi I was using FLMaterializer materializationFromFileNamed: filename to read fuel files. Until yesterday everything was fine, but today I updated Pharo and received the error "'Materialization error. Unexpected stream version 19 where it should be 193." I guess that a new version of fuel cannot (simply) read old versions files. Is there a way to know in which version of fuel a file was written and use that version to read it? thanks Lorenzo

#new version #basicNew when materializing (SIXX/Fuel difference)

by Mariano Martinez Peck

Hi guys, I found this a bit strange and arguable. Upon materialization, for normal classes, Fuel uses #basicNew to instantiate objects and then sets its instances variables values getting them from the stream.... Today I found that SIXX sends #new first (*and hence #initialize is sent*) and after, if fails, it tries, #basicNew. This 2 approaches have different results. Which one would you expect? -- Mariano http://marianopeck.wordpress.com

I would not go for petitparser personally. My experience, speaking of performance and error reporting, not so great. I have one question: If you replace RBParser with green-field implementation, how would you deal with the rest of RB stuff? Refactorings, lint etc, which are all based of RBParser API? Best, Jan

Hi Uko, It's at http://forum.world.st/ANN-GitFileTree-with-no-git-command-line-at-all-td474… In short, have a look at either ConfigurationOfAltBrowser or ConfigurationOfSmaCC (baseline20).

git and metacello

by Yuriy Tymchuk

Hi guys! Sorry if Iâm bothering you, but I wasnât able to find any workflow or so on with git. Iâve started to use file-tree, but for now on I donât understand how to make it work with metacello. Also is there some project like that built on jenkins, so I can set up similar job. Cheers Uko

Re: [Pharo-dev] Floats problem with SIXX between Pharo and GemStone

by phil＠highoctane.be

Nicolas, Would you mind putting this in a configuration so that we can load it easily in 3.0? I agree with you that this parsing story should be as best as possible. And it is not so right now. Phil
