How to Avoid Name Collisions in Go Package Imports?

Overcoming Go's Name Collision with Package Imports

In Go, it's common practice to utilize packages to organize and reuse code, but occasionally, you may encounter a collision in function names between different packages. This can hinder your ability to call a function without specifying its package name.

The example provided in the question showcases such a scenario, where you wish to import the fmt package and call its Println function without explicitly mentioning fmt.

While Go doesn't provide a direct equivalent to C#'s static import, there are two viable alternatives:

1. The Dot Import

The specification allows for the use of the explicit period (.) during import to make all exported identifiers from that package available without a qualifier.

Example:

package main

import (
    . "fmt"
)

func main() {
    Println("Hello, playground")
}

2. Package-Level Variables or Type Aliases

Another approach is to create package-level variables that reference the functions you need.

Example:

package main

import (
    "fmt"
)

var Println = fmt.Println
type ScanState = fmt.ScanState // type alias

func main() {
    Println("Hello, playground")
}

Caution:

While the dot import offers a solution, it's discouraged within the Go community due to its potential for code readability issues. The preferred method is to use package-level variables or type aliases, which provide greater clarity.
