I'm writing a python library that operates on C++ code stored in string literals. The normal use case is to create a code object like so:

code(r"""
void* foo() {
   return NULL;
}
""")

The library is meant to work in Jupyter Lab which uses Code Mirror for syntax highlighting/editing, so I'd like to extend Code Mirror to identify calls to code() and apply C++ syntax highlighting to its argument, so it'd look something like this:

code(r""" # python highlighting

void* foo() {  // C++ higlighting
   return NULL;
}

""")

I know how to do something similar in Pygments, but I'm not sure where to get started with Code Mirror.
