[Pharo-users] How to write out simple Json?

I am stumped about how to write out some simple json (for a config file). I didn't think I need Neo, and STONJSON would be fine but it seems like creating items like: { 'id'-> self id. 'name' -> self name } gives an error about the association. I think you have to do: { ('id'-> self id) asDictionary. ('name' -> self name) asDictionary } everywhere…. But when I switch over to NeoJsonWriter it also complains about Assocations too. I just want a simple output like: { "id" : 12, "name" : "tim” } I thought it was simple to do this? Am I missing something obvious. Tim
