Hi Peter, This functionallity is already available in STON where it preserves the order when you use an OrderedDictionary. And was implemented for the usecase of dealing with fileout and versioning. Perhaps the same could be added to NeoJson so that instead of some magic flag you provide an OrderedDictionary sorted as you would like and it would then preserve the order.
If you aim to use it to preserve metada for filetree then there is a patch for that which can be found at https://github.com/DraagrenKirneh/PharoUtilities/tree/master/FileTreeFix Best regards, Henrik -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
