Woah, please don't tell me you're actually trying to read the parser C++
code (Gmsh.tab.cpp, etc.) :-)

This is automatically generated by lex and yacc (well, actually, flex
and bison) from the two human-readable files Gmsh.l and Gmsh.y. Just
look for "nurbs" in Gmsh.y to see what the syntax is.

To regenerate the C++ files when you change Gmsh.l or Gmsh.y, just type
"make parser".

Yes, you can find the current implementation in Mesh/Nurbs.cpp.
