Four types: Angle, HourAngle, RA, and Time, useful in astronomy applications.
These types are all angle-like types. The Time type is at least angle-related. It has conversions to and from the other types and has a function to wrap a Time value to the fractional part of a day.
This package supports two other packages, github.com/soniakeys/sexagesimal and github.com/soniakeys/meeus. The sexagesimal package adds formatting to the four types defined here. The meeus package implements a large colection of astronomy algorithms.
Technically, go get github.com/soniakeys/unit is sufficient as usual.
The tests also require the sexagesimal package, so use the -t option to prompt
go get to find it as a test dependency:
go get -t github.com/soniakeys/unit
Experimentally, you can try vgo.
To run package tests, clone the repository -- anywhere! it doesn't have to be under GOPATH -- and from the cloned directory run
vgo test
Vgo will fetch the sexagesimal test dependency as needed and run the unit package tests.
If you only need unit as dependency of some other package that you are
installing, the normal installation of that package will likely install unit
for you. Try that first.
