This fixes several issues with compatibility with C++20. C++23 was also
tested, but apparently it does not have any additional breaking changes
compared to C++20 (or we don't have those).
VCMI still uses C++17 as before - goal is only to make potential
transition easier.
There were 2 cases that are deprecated in C++20 that we use:
- Floating point operations on enums are deprecated
- `this` can no longer be captured when using default capture by value
`[=]`
Both of those should now be replaced with code that works fine in both C+
+17 and in C++20 mode
- class CGuiHandler is now called GameEngine to better describe its
functionality
- renamed global GH to more clear ENGINE
- GH/ENGINE is now unique_ptr to make construction / deconstruction
order more clear and to allow interface / implementation split
- CGuiHandler.cpp/h is now called GameEngine.cpp/h and located in root
directory of client dir
All text processing code is now located in lib/texts.
No changes other than code being moved around and adjustment of includes
Moved without changes:
Languages.h -> texts/Languages.h
MetaString.* -> texts/MetaString.*
TextOperations.* -> texts/TextOperations.*
Split into parts:
CGeneralTextHandler.* -> texts/CGeneralTextHandler.*
-> texts/CLegacyConfigParser.*
-> texts/TextLocalizationContainer.*
-> texts/TextIdentifier.h
- Test only for Cmd modifier key when processing mouse clicks
- Test both Ctrl and Cmd modifier key when processing keyboard input
- This logic is now used for all Apple systems - macOS and iOS
- added compatibility method to Canvas to allow SDL_Surface access
- added drawBorder method to Canvas to replace CSDL_Ext method
- added drawColor method to Canvas to replace CSDL_Ext method
- minor changes to Tavern and Trade windows to adapt to new API
