============
|
||
|
|
|
||
|
|
The include policy for the files in app/ is as follows:
|
||
|
|
|
||
|
|
Each subdirectory has a <module>-types.h file which defines the type
|
||
|
|
space known to this module. All .c files in the directory include this
|
||
|
|
(and only this) <module>-types.h file. <foo>-types.h files from other
|
||
|
|
modules are included from the <module>-types.h file only. This way
|
||
|
|
<module>-types.h becomes the only place where the namespace known to a
|
||
|
|
module is defined.
|
||
|
|
|
||
|
|
|
||
|
|
***** .h files *****
|
||
|
|
|
||
|
|
No .h file includes anything, with two exceptions:
|
||
|
|
|
||
|
|
- objects include their immediate parent class
|
||
|
|
- if the header uses stuff like time_t (or off_t), it includes
|
||
|
|
<time.h> (or <sys/types.h>). This only applies to system stuff!
|
||
|
|
|
||
|
|
|
||
|
|
***** .c files *****
|
||
|
|
|
||
|
|
The include order of all .c files of a module is as follows:
|
||
|
|
|
||
|
|
/* any file from app/core/ */
|
||
|
|
|
||
|
|
#include "config.h" /* alyways and first */
|
||
|
|
|
||
|
|
#include <glib.h> /* *only* needed if the file needs stuff */
|
||
|
|
/* like G_OS_WIN32 for conditional inclusion */
|
||
|
|
/* of system headers */
|
||
|
|
|
||
|
|
#include <system headers> /* like <stdio.h> */
|
||
|
|
|
||
|
|
#include <glib-object.h>
|
||
|
|
|
||
|
|
#include "libgimpfoo/gimpfoo.h" /* as needed, e.g. "libgimpbase/gipmbase.h" */
|
||
|
|
#include "libgimpbar/gimpbar.h"
|
||
|
|
|
||
|
|
#include "core-types.h" /* and no other foo-types.h file */
|
||
|
|
|
||
|
|
#include "base/foo.h" /* files from modules below this one */
|
||
|
|
#include "base/bar.h"
|
||
|
|
|
||
|
|
#include "gimp.h" /* files from this module */
|
||
|
|
#include "gimpimage.h"
|
||
|
|
#include "gimpwhatever.h"
|
||
|
|
|
||
|
|
#include "libgimp/gimpintl.h" /* if needed, *must* be the last include */
