Support currency conversion rates
Qalculate! supports fetching currency rates from the internet and permits queries like 1 USD to EUR, or even 1$/gallon to €/liter. It would be nice to have that function in this mobile app.
Totally agree! For that, libcurl has to be built and support for fetching the exchange rates must be enabled when building libqalculate. I created an issue for that in libqalculate-android: https://github.com/mr-kenhoff/libqalculate-android/issues/4
This is technically separate from including libcurl, but if possible I'd make sure the exratescommand works so you can refresh on demand
In the interest of collaboration, here is the code in use by my own app: maculate: https://github.com/toastclub/maculate/blob/f3e6f840510c149fa1fea6f817a32842829687e8/libqalc/Qalculate/main.cpp#L116-L164
I know how hard it is to read the code of qalculate sometimes so I thought this could be a good starting point. (I'm toying with RIIR)
One oddity I've not figured out yet is that bitcoin is inversed but nothing else is as far as I can tell.
My next challenge is to figure out how to reimplement plotting...
