Adapting old watchfaces:

• When resolving conflicts, delete clock.h/.cpp, keep both in CMakeLists.cpp, accept current in SettingWatchFace.cpp, and keep both if there are any changes in fonts.
• Add entry to WatchFace enum in displayapp/apps/Apps.h.in
• Remove DisplayApp* app param from constructor in .h and .cpp and remove Screen(app) from initializer list on constructor in .cpp
• Add const to batteryController and bleController is present in constructor params and in private members in .h
• In .cpp, remove #include <date/date.h> and convert calls to get time to format like in working watch faces. For example:

    auto newDateTime = currentDateTime.Get();

    auto dp = date::floor<date::days>(newDateTime);
    auto time = date::make_time(newDateTime - dp);

    uint8_t hour = time.hours().count();
    uint8_t minute = time.minutes().count();

with

    uint8_t hour = dateTimeController.Hours();
    uint8_t minute = dateTimeController.Minutes();

, add

Utility::DirtyValue<std::chrono::time_point<std::chrono::system_clock, std::chrono::days>> currentDate;

to .h

• Remove motionSensorOk = motionController.IsSensorOk(); and reference to motionSensorOk in following if
• In .h add #include "utility/DirtyValue.h" and replace all DirtyValue<> vars with Utility::DirtyValue<>
• Add WatchFaceTraits:

    template <>
   struct WatchFaceTraits<WatchFace::Digital> {
     static constexpr WatchFace watchFace = WatchFace::Digital;
     static constexpr const char* name = "Digital face";

     static Screens::Screen* Create(AppControllers& controllers) {
       return new Screens::WatchFaceDigital(controllers.dateTimeController,
                                            controllers.batteryController,
                                            controllers.bleController,
                                            controllers.notificationManager,
                                            controllers.settingsController,
                                            controllers.heartRateController,
                                            controllers.motionController,                                             controllers.filesystem
                                            *controllers.weatherController);
     };
 

      static bool IsAvailable(Pinetime::Controllers::FS& filesystem) {
        return Screens::WatchFaceCasioStyleG7710::IsAvailable(filesystem);
      }
   };

modify as necesary.

• Add include to UserApps.h: #include "displayapp/screens/WatchFace---.h"
• Add to displayapp/apps/CMakeLists.txt
