JSON woes

[Bill Meyer 337]

My colleagues tell me they have identified a problem in the copy of superobject which we use in D2007. The problem is not present in the version we use in XE7, but I am not aware of what may be different, and no one appears to have noted when and where the two versions were acquired.

I am also told that there have been a great many forks of superobject, which makes it all more confusing.

What version do people here use, and what is considered the gold standard now, if there is one?

Using the std TJson class in REST.Json. 

Probably not considered gold std.

I'm using the standard System.JSON library. It supports everything I needed until now, except merging.

SuperObject is open-source.  Just diff the two versions to see what is different between them.  Or, just update the D2007 code to use the same version that the XE7 code is using.  Or update both codes to the latest version.

So pick ONE and stick with it for both codes.

I don't do JSON processing in my code.

I integrated SuperObject into the ICS library two years ago since we support D7 to 10.3 with mostly the same code, I used v1.2 from https://github.com/hgourvest/superobject

 which is not the latest, later versions added time zone stuff which made it harder to stabilise and duplicated stuff we had already.  With a few tweaks and new compiler version checks, it works fine on all those versions of Delphi.  https://svn.overbyte.be/svn/ics/trunk/Source/OverbyteIcsSuperObject.pas

mORMot's TDocVariant supports back to D7 so I think it should work well with D2007 all the way to the newest Delphi.

If anyone cares to try another alternative, I've created my own JSON handler, based on work I had done before to handle BSON for a rough-and-raw handler for MongoDB: https://github.com/stijnsanders/jsonDoc#jsondoc

I really dislike long lists of overloads, so it extensively uses Delphi's own Variant type. It also tries to prevent too much allocation of Variant instances. If you need to process identical or similar JSON objects in sequence, re-use the same instance to re-use the allocated keys and values.
