clock module: Support for other calendars e.g. Hijri, Chinese ...

[zefr0x]

As what some people know, English is not the only language in the world, and USA is not the only country in the world.

The Gregorian calendar is also not the only calendar in the world. Of course some of them are historical and no one use them, but some of them are used officially in some countries like the Hijri (Islamic), Chinese, Japanese (just the era name), Hebrew and the Julian calendar.

I know that I can use a custom module, but I think it should be easy to implement since we have the date C++ library which is based on the <chrono> header. (I'm not great in C++ and I haven't search a lot, so there might be a better library or some problems)

Personally I am interested in the Hijri calendar since I use it a lot, and I am working in a custom module to have it for now.

Also, why is Sunday first? Any way to change to Monday?

I'd also like to change this. The function for this is probably here:

Waybar/src/modules/clock.cpp

Line 465 in ccc3c13

auto waybar::modules::Clock::first_day_of_week() -> weekday {

Any way to change/configure this hardcoded Sunday value?

fwiw I switched to using cal -m directly. https://github.com/mattfbacon/dotfiles/blob/88ffd825eba12406e0ce43be24edf3dffa47142b/framework/sway/.config/waybar/clock.py
