Examples
// import with a nice name
import (
"github.com/VerbalExpressions/GoVerbalExpressions" // imports verbalexpressions package
"fmt"
)
func main () {
v := verbalexpressions.New().
StartOfLine().
Then("http").
Maybe("s").
Then( "://").
Maybe("www.").
AnythingBut(" ").
EndOfLine()
testMe := "https://www.google.com"
if v.Test(testMe) {
fmt.Println("You have a valid URL")
} else {
fmt.Println("URL is incorrect")
}
}
We try to give alias method and/or helpers. For example:
// s will be "We have a blue house"
s := verbalexpressions.New().Find("red").Replace("We have a red house", "blue")
// c will be:
// [
// ["http://www.google.com", "http://", "www.google.com"]
// ]
c := verbalexpressions.New().
BeginCapture().
Find("http").Maybe("s").Find("://").
EndCapture().
BeginCapture().
Find("www.").Anything().
EndCapture().
Captures("http://www.google.com")
// check c[0][1] => http://
// c[0][2] => www.google.com
