Golang: regexp

By Xah Lee. Date: .

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

package main

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)

}
