介紹
在我們的日常開發中，有時候會遇到一些需要處理字符串的任務。并且我們也知道這是需要正則表達式的，但是礙于系統地學習正則表達式費時費力，而且一段時間不使用又很容易遺忘。最近找到了go相關的一個正則表達式第三方庫——commonregex。當然，我并不是說沒必要去學習正則表達式。
使用
創建目錄并初始化
mkdir commonregex && cd commonregex
go mod init commonregex
安裝commonregex
go get -u github.com/mingrammer/commonregex
簡單使用
package main
import (
"fmt"
cregex "github.com/mingrammer/commonregex"
)
func main() {
text := `John, please get that article on www.linkedin.com to me by 5:00PM on Jan 9th 2012. 4:00 would be ideal, actually. If you have any questions, You can reach me at (519)-236-2723x341 or get in touch with my associate at harold.smith@gmail.com`
dateList := cregex.Date(text)
timeList := cregex.Time(text)
linkList := cregex.Links(text)
phoneList := cregex.PhonesWithExts(text)
emailList := cregex.Emails(text)
fmt.Println("date list:", dateList) // ['Jan 9th 2012']
fmt.Println("time list:", timeList) // ['5:00PM', '4:00']
fmt.Println("link list:", linkList) // ['www.linkedin.com', 'harold.smith@gmail.com']
fmt.Println("phone list:", phoneList) // ['(519)-236-2723x341']
fmt.Println("email list:", emailList) // ['harold.smith@gmail.com']
}
