Golang interface binding to the Swiss Ephemeris C library v2.10.01.

Swiss Ephemeris is a function package of astronomical calculations that serves the needs of astrologers, archeoastronomers, and, depending on purpose, also the needs of astronomers. It includes long-term ephemerides for the Sun, the Moon, the planets, more than 300.000 asteroids, historically relevant fixed stars and some “hypothetical” objects.

Download the Swiss Ephemeris Library here. After compiling the library, copy the libswe.so file to /usr/local/lib/

$ cp libswe.so /usr/local/lib/

Get the library with the following command:

$ go get github.com/mshafiee/swephgo

package main

import (
	"fmt"
	"github.com/mshafiee/swephgo"
)

func main() {
	sweVer := make([]byte, 12)
	swephgo.Version(sweVer)
	fmt.Printf("Library used: Swiss Ephemeris v%s\n", sweVer)
}

RUN:

$ go run main.go
