As you may recall, I wrote a JSON compiler and decompiler in October. After running a bunch of tests against other people's JSON, I was satisfied that it worked, and moved on. I mostly focused on the compiler, because that's usually the hard part, trying to understand all the variables that people can throw at you. JSON was, as advertised, pretty easy to work with (though not as easy, imho, as it could have been). No matter.
Each group of news bits is organized as a bunch of scalar data, like feed name, url, when the feed was last read, etc. Then there are one or more news items. If there's one item I just include a struct named item. If there's more than one I include a list of structs. The list is named item. I understood this is the convention for repeating elements in JSON.
This causes problems for people in some languages because (apparently) it's hard for them to deal with an object without, in advance, knowing its type. So they say the solution is simple, always make it a list. Simple for them, but...
PS: I have a workaround I can do fairly quickly that side-steps the problem, so it won't ultimately be a deal-stopper. But I'd like to solve the problem entirely in the serializer if possible, so the solution can be work in other cases.
