gopath
gopath returns the current user's GOPATH, compatible with Go 1.8+
That is, it returns the value of the environment variable GOPATH,
and if that is not set, the directory named go in the user's home
directory.
What "home directory" means is platform-specific. gopath uses
mitchellh/go-homedir to
find out what the user's home directory is.
Example
package main
import (
"fmt"
"log"
"github.com/thomasheller/gopath"
)
func main() {
p, err := gopath.Get()
if err != nil {
log.Fatalf("Error getting GOPATH: %v", err)
}
fmt.Println(p)
// Output:
// /home/user/go (or whatever GOPATH is set)
}
For convenience, gopath also provides a function to join the GOPATH
with one or more path elements, like filepath.Join:
package main
import (
"fmt"
"log"
"github.com/thomasheller/gopath"
)
func main() {
p, err := gopath.Join("src/github.com/thomasheller/gopath")
if err != nil {
log.Fatalf("Error getting GOPATH: %v", err)
}
fmt.Println(p)
// Output:
// /home/user/go/src/github.com/thomasheller/gopath (or whatever GOPATH is set)
}
