Golang: regexp

By Xah Lee. Date: . Last updated: .

Here's example of using regular expression to replace text.

package main

// replace Alice by Mary

import "fmt"
import "regexp"

var longtext = `Alice was beginning to get very tired of sitting by her
sister on the bank, and of having nothing to do: once or twice she had
peeped into the book her sister was reading, but it had no pictures or
conversations in it, «and what is the use of a book,» thought Alice «without
pictures or conversation?».`

func main() {
	var re = regexp.MustCompile(`(?i:alice)`)
	var replaceStr = "Mary"
	var result = re.ReplaceAllLiteralString(longtext, replaceStr)
	fmt.Printf("%v\n", result)
}
