CPPON

C++ Object Notation for general use, specifically: X3D and glTF (I hope)

CPPON examples

See .h files in in below link. During C++ compilation, CPPON is #included into a C++ function. https://github.com/coderextreme/CPPON/tree/main/cplusplus/net/coderextreme/data

Parsers

There are Java, JavaScript and partial C++ parsers in below link. Currently the parsers are based on an ANTLR4 grammar. https://github.com/coderextreme/CPPON/tree/main/cplusplus/net/coderextreme

ANTLR4 Grammar

Here's an ANTLR4 Grammar for CPPON:

DOM to C++ Serializer

Here's how I create C++ from DOM (json parameter is ignored)

https://github.com/coderextreme/CPPON/blob/main/node/CppFunctionBodySerializer.js

Here's my more domain-specific (for X3D) JSON to DOM converter.

Next Steps

I have written a CPPON to DOM converter, here:
