os.PathSeparator

In the Go language, the os package provides a platform-independent interface to operating system (Unix-like) functionality. The PathSeparator constant is used to get the operating specific path separator. The value of PathSeparator constant may be different based on the operating system.

Syntax:

PathSeparator int32

Implementation in the package source code:

PathSeparator     = '/' 
// Here, '/' is Unix-based path separator

Parameter(s):

• None

Return Value:

The return type of the os.PathSeparator constant is an int32, it returns '/' (Unix-based operating system) i.e., the value of PathSeparator constant is '/' on Unix operating system.

Example 1:

// Golang program to demonstrate the
// example of PathSeparator constant

package main

import (
	"fmt"
	"os"
)

func main() {
	// Printing the type and value
	fmt.Printf("Type of os.PathSeparator: %T\n",
		os.PathSeparator)
	fmt.Printf("Value of os.PathSeparator: %c\n",
		os.PathSeparator)
}

Output:

Type of os.PathSeparator: int32
Value of os.PathSeparator: /

Example 2:

// Golang program to demonstrate the
// example of PathSeparator constant

package main

import (
	"fmt"
	"os"
	"path/filepath"
)

func main() {
	// Making a cross-platform file path
	// Example:
	// For unix: 'dir/example',
	// For windows: 'dir\example'

	path1 := "dir" + string(os.PathSeparator) + "example"
	fmt.Println("path1: " + path1)

	path2 := filepath.FromSlash("dir/example")
	fmt.Println("FromSlash (path1): " + path2)
}

Output:

path1: dir/example
FromSlash (path1): dir/example
