Extract urls from text using regular expressions.
go get -u mvdan.cc/xurls
import "mvdan.cc/xurls"
func main() {
xurls.Relaxed().FindString("Do gophers live in golang.org?")
// "golang.org"
xurls.Strict().FindAllString("foo.com is http://foo.com/.", -1)
// []string{"http://foo.com/"}
}
Note that the funcs compile regexes, so avoid calling them repeatedly.
go get -u mvdan.cc/xurls/cmd/xurls
$ echo "Do gophers live in http://golang.org?" | xurls
http://golang.org
