Multiline String in Golang is a fundamental concept used to store and manipulate text. Multiline strings are strings that span across multiple lines, often used for embedding blocks of text like documentation, SQL queries, or templates. While Go doesn’t have a built-in syntax for multiline strings like some other languages, there are several ways to achieve multiline strings effectively. In this tutorial, we’ll explore different methods to create multiline strings in Go.

  • Using String Concatenation
  • Using Join Function
  • Conclusion

Method 1: Using Raw String Literals

Raw string literals in Go allow you to include newline characters directly within the string without any escaping.

package main

import "fmt"

func main() {
	multilineStr := `This is a multiline
string created using raw
string literals.`

	fmt.Println(multilineStr)
}

Output:

This is a multiline
string created using raw
string literals.

Method 2: Using String Concatenation

You can create multiline strings by concatenating multiple string literals, each on a separate line.

package main

import "fmt"

func main() {
	multilineStr := "This is a multiline\n" +
		"string created using\n" +
		"string concatenation."

	fmt.Println(multilineStr)
}

Output:

This is a multiline
string created using
string concatenation.

Method 3: Using Join Function

The strings.Join() function can be used to create a multiline string by joining an array of strings.

package main

import (
	"fmt"
	"strings"
)

func main() {
	lines := []string{
		"This is a multiline",
		"string created using",
		"the strings.Join() function.",
	}

	multilineStr := strings.Join(lines, "\n")
	fmt.Println(multilineStr)
}

Output:

This is a multiline
string created using
the strings.Join() function.

Conclusion

In this tutorial, you’ve learned various methods to create multiline strings in Go. Each method offers a way to structure your text over multiple lines, catering to different coding styles and preferences. Choose the method that best suits your needs and helps maintain code readability. Happy coding!
