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)
}
