xurls

Extract urls from text using regular expressions.

go get github.com/mvdan/xurls

import "github.com/mvdan/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/"}
}

Relaxed is around five times slower than Strict since it does more work to find the URLs without relying on the scheme:
