This script generates the actual binding code to read a // blender file with a possibly different DNA into our structures. // Only `struct` declarations are considered and the following // rules must be obeyed in order for the script to work properly: // // * C++ style comments only // // * Structures may include the primitive types char, int, short, // float, double. Signed specifiers are not allowed on // integers. Enum types are allowed, but they must have been // defined in this header. // // * Structures may aggregate other structures, unless not defined // in this header. // // * Pointers to other structures or primitive types are allowed. // No references or double pointers or arrays of pointers. // A pointer to a T is normally written as std::shared_ptr, while a // pointer to an array of elements is written as boost:: // shared_array. To avoid cyclic pointers, use raw pointers in // one direction. // // * Arrays can have maximally two-dimensions. Any non-pointer // type can form them. // // * Multiple fields can be declare in a single line (i.e `int a,b;`) // provided they are neither pointers nor arrays. // // * One of WARN, FAIL can be appended to the declaration ( // prior to the semicolon to specify the error handling policy if // this field is missing in the input DNA). If none of those // is specified the default policy is to substitute a default // value for the field. // // warn if field is missing, substitute default value #ifdef WARN # undef WARN #endif #define WARN // fail the import if the field does not exist #ifdef FAIL # undef FAIL #endif #define FAIL struct Object;
