Can I Import an Entire Go Package Globally for Direct Access?
Importing an Entire Package Globally
Question
Can I import all contents of a package into my code without the need to prefix function or variable names with the package name?
Answer
Yes, you can use a special import syntax to achieve this.
According to the Go Programming Language Specification:
If an explicit period (.) appears instead of a name, all the package's exported identifiers declared in that package's package block will be declared in the importing source file's file block and must be accessed without a qualifier.
In other words, by importing a package with a dot (.) as the package name, you instruct the compiler to import all exported symbols (functions, variables, etc.) from that package and make them available in your code without requiring the package name prefix.
Example
Consider the following example code:
<code class="go">import "fmt" func main() { fmt.Println("Hello, world") }</code>
To import all functions and variables from the fmt package without the fmt. prefix, you can use the following code:
<code class="go">import . "fmt" func main() { Println("Hello, world") }</code>
This updated code will produce the same output as the original code snippet.
You can verify this behavior in the Go Playground: https://play.golang.org/p/xl7DIxxMlU5
