xurls

GoDoc

Extract urls from text using regular expressions. Requires Go 1.13 or later.

import "mvdan.cc/xurls/v2"

func main() {
	rxRelaxed := xurls.Relaxed()
	rxRelaxed.FindString("Do gophers live in golang.org?")  // "golang.org"
	rxRelaxed.FindString("This string does not have a URL") // ""

	rxStrict := xurls.Strict()
	rxStrict.FindAllString("must have scheme: http://foo.com/.", -1) // []string{"http://foo.com/"}
	rxStrict.FindAllString("no scheme, no match: foo.com", -1)       // []string{}
}

Since API is centered around regexp.Regexp, many other methods are available, such as finding the byte indexes for all matches.

Note that calling the exposed functions means compiling a regular expression, so repeated calls should be avoided.

cmd/xurls

To install the tool globally:

cd $(mktemp -d); go mod init tmp; GO111MODULE=on go get mvdan.cc/xurls/v2/cmd/xurls

$ echo "Do gophers live in http://golang.org?" | xurls
http://golang.org
