import ( "fmt" "go/token" "go/types" ) func main() { // Valid package path path1 := "github.com/user/repo" if _, err := types.CheckImportPath(path1); err != nil { fmt.Println(err) } // Invalid package path path2 := "abc/def#ghi" if _, err := types.CheckImportPath(path2); err != nil { fmt.Println(err) } }
import ( "fmt" "go/token" "go/types" ) func main() { // Original package path path1 := "github.com/user/repo" fmt.Println("Original path:", path1) // Change the package name path2, _ := types.NewImportPath(path1 + "/newname") fmt.Println("New path:", path2.Path) }This example demonstrates how to manipulate a package path. In this example, we create a new package path by appending a new name to the original package path. The `NewImportPath` function is used to create the new package path object and the `Path` field is used to get the actual package path string. From the above examples, we can determine that the package library is a part of the standard Go language packages. It is used to work with package import paths in Go programs.
