* \section aboutdna About the DNA module
|
|
*
|
|
* The DNA module holds all type definitions that are serialized in a
|
|
* blender file. There is an executable that scans all files, looking
|
|
* for struct-s to serialize (hence sdna: Struct \ref DNA). From this
|
|
* information, it builds a file with numbers that encode the format,
|
|
* the names of variables, and the place to look for them.
|
|
*
|
|
* \section dnaissues Known issues with DNA
|
|
*
|
|
* - Function pointers:
|
|
*
|
|
* Because of historical reasons, some function pointers were
|
|
* untyped. The parser/dna generator has been modified to explicitly
|
|
* handle these special cases. Most pointers have been given proper
|
|
* proto's by now. DNA_space_types.h::Spacefile::returnfunc may still
|
|
* be badly defined. The reason for this is that it is called with
|
|
* different types of arguments. It takes a char* at this moment...
|
|
*
|
|
* - Ignoring structs:
|
|
*
|
|
* Sometimes we need to define structs in DNA which aren't written
|
|
* to disk, and can be excluded from blend file DNA string.
|
|
* in this case, add two '#' chars directly before the struct. eg.
|
|
*
|
|
* \code{.c}
|
|
* #
|
|
* #
|
|
* typedef struct MyStruct {
|
|
* int value;
|
|
* } MyStruct;
|
|
* \endcode
|
|
*
|
|
* Ignored structs can only be referred to from non-ignored structs
|
|
* when referred to as a pointer (where they're usually allocated
|
|
* and cleared in `readfile.c`).
|
|
*
|
|
* - %Path to the header files
|
|
*
|
|
* Also because of historical reasons, there is a path prefix to the
|
|
* headers that need to be scanned. This is the BASE_HEADER
|
|
* define. If you change the file-layout for DNA, you will probably
|
|
* have to change this (Not very flexible, but it is hardly ever
|
|
* changed. Sorry.).
|
|
*
|
|
* \section dnadependencies Dependencies
|
|
*
|
|
* DNA has no external dependencies (except for a few system
|
|
* includes).
