xurls

Extract urls from text using regular expressions. Requires Go 1.10.3 or later.

import "mvdan.cc/xurls/v2"

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.

cmd/xurls
