Errors in vim but not in run/build. Lots of missing stuff from Arduino.h

I don’t know where to really start here. I have working code, I can build it and upload it to the target. But in my editor it is showing all errors. It seems like it isn’t recognizing the ‘Arduino.h’ include. Also, it doesn’t seem to recognize the any of the types in the variables.

My guess is maybe I am writing arduino code instead of c++? If that is the case, can you point out an example of where I am mixing up the languages? I just don’t know where to look since the compiler isn’t producing any errors.
