A simple package to get environment variables, returns a string or an error. Go Buffalo already had a ENV package named envy it seems. Naming stuff is hard. Oh well.
Use go get github.com/shindakun/envy to install into Go or use as a Go module.
Import github.com/shindakun/envy, see full example below.
package main
import (
"fmt"
"github.com/shindakun/envy"
)
func main() {
gopath, err := envy.Get("GOPATH")
if err != nil {
panic(err)
}
fmt.Println(gopath)
}
