You can rename APIs using rename.py and all the code and documentation will be updated, and entries will be added to WhatsNew.txt and docs/README-migration.md.
e.g.
rename.py SDL_foo.h function SDL_CreateFoo SDL_FooCreate
SDL_oldnames.h is included in the SDL header, and if you define SDL_ENABLE_OLD_NAMES, will redefine the old API functions to call the new ones, and if not, will define them as a symbol letting you what the new API function is.
SDL.h now exists solely as a header that includes everything else, instead
of one that forces you to include everything else when you just want the
declaration for SDL_Init().
Fixes#6840.
makes the SDL_main code shorter
Also added a generic SDL_RunApp() implementation for platforms that
don't really need it.
Some platforms (that use SDL_main but haven't been ported yet) are
still missing, but are added in the following commits.
and move the #undef main and #define main SDL_main to the start/end of
SDL_main_impl.h instead of repeating it in every platform implementation
Thanks to SDL_N3DSRunApp we don't need the #include <3ds.h> in
SDL_main_impl.h - that caused conflicts with testthread.c, because both
have (different) ThreadFunc typedefs.
As the implementation requires C++, the user will have to include
SDL_main.h in a C++ source file (that needs to be compiled with /ZW).
It's ok to keep the standard main() implementation in plain C and use
an otherwise empty C++ source file for the SDL_main implementation part,
if both source files #include <SDL3/SDL_main.h>
Including SDL_main.h in a C source file will print a message at
compilation (when building for WinRT or possibly other not yet implemented
platforms that require C++ for main), to remind the user of also
including it in a .cpp source file. This message/warning can be disabled
with #define SDL_MAIN_NOIMPL before including SDL_main.h in the C file.
When including it in a .cpp file, there will be a compiler error with
helpful message if it's not compiled with /ZW
For this I renamend _SDL_MAIN_NOIMPL to SDL_MAIN_NOIMPL, because now it's
not for internal use only anymore, but also useful for users (that want
their main() function in a different file than the SDL_main implementation)
Add a project for the testdraw2.c test to the WinRT solution to at least
get some minimal testing on WinRT.
I won't add all tests because it's a lot of manual clicking per test,
but this should be better than nothing :)
Also adjusted iOS demo's includes to <SDL3/..> and explicit SDL_main.h
untested, I don't have Xcode (or a Mac, for that matter)
The xcode projects (for both Xcode-iOS/ and Xcode/) will probably
have to be adjusted for the SDL_main changes to work, but now at least
the iOS demo source should work as is :)
