How to Achieve Namespace Aliasing in Go?

Go Equivalent for C 's Namespace Aliasing

In C , the using keyword allows you to alias a specific class or function from a namespace. However, Go lacks a direct equivalent for this.

Import Entire Namespace

The provided solution in the original question imports the entire common namespace. If you need to use all objects within the namespace, this method is appropriate:

<code class="go">import (
  . "common"
)</code>

Partial Namespace Import

For importing only specific objects, a close approximation in Go is to use a series of variable assignments:

<code class="go">import (
    "fmt"
    "strings"
)

var (
    Sprintf = fmt.Sprintf // Alias for fmt.Sprintf
    HasPrefix = strings.HasPrefix // Alias for strings.HasPrefix
)</code>

This approach provides readability but compromises efficiency as the compiler cannot optimize function calls. Additionally, it introduces the imported packages' names into the file scope, unlike C 's using.
