- Does anyone know of a PD tool available with portable(ish) source for
- removing surplus #include directives? For example:
-
- /* "file2.h" */
- #include "file1.h"
-
- -------------------
-
- /* "file3.h" */
- #include "file1.h"
- #include "file2.h"
-
- -------------------
-
- #include "file1.h" could be removed from "file3.h". This sort of thing
- saves a lot of compiler time without having the chore of typing:
-
- #ifndef __file1_h
- #include "file1.h"
- #endif
-
- Ideally the tool should be able to remove the #ifndef structure as well.
-
- I know I will still need to do:
-
- /* "file1.h" */
- #ifndef __file1_h
- #define __file1_h
- /* Body of file */
- #endif
-
- but having an additional check around any #include directives or not
- doing the include at all saves the compiler lots of time having to load
- a file it's already included.
-
- My C compiler does have an include_only_once pragma, but it doesn't seem
- to work in CFront.
