How to get path of imported package

Question

I\'m having difficulty when trying to get path of imported package. When I print result of os.Getwd() inside imported package, it\'s showing same path like on <

Answer 1

PkgPath() only can retrieve the package path for non-pointer

// If the type was predeclared (string, error) or not defined (*T, struct{},
// []int, or A where A is an alias for a non-defined type), the package path
// will be the empty string.
func packageName(v interface{}) string {
    if v == nil {
        return ""
    }

    val := reflect.ValueOf(v)
    if val.Kind() == reflect.Ptr {
        return val.Elem().Type().PkgPath()
    }
    return val.Type().PkgPath()
}

If you can get a reference to something in the package, you can use reflect to get the import path.

Here's an example on Play:

package main

import (
    "bytes"
    "fmt"
    "reflect"
)

func main() {
    var b bytes.Buffer
    fmt.Println(reflect.TypeOf(b).PkgPath())
}
