# xurls

[](https://godoc.org/mvdan.cc/xurls)
|
|
|
|
Extract urls from text using regular expressions. Requires Go 1.13 or later.
|
|
|
|
```go
|
|
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](https://golang.org/pkg/regexp/#Regexp),
|
|
many other methods are available, such as finding the [byte indexes](https://golang.org/pkg/regexp/#Regexp.FindAllIndex)
|
|
for all matches.
|
|
|
|
Note that calling the exposed functions means compiling a regular expression, so
|
|
repeated calls should be avoided.

To install the tool globally:
|
|
|
|
cd $(mktemp -d); go mod init tmp; GO111MODULE=on go get mvdan.cc/xurls/v2/cmd/xurls
|
|
|
|
```shell
|
|
$ echo "Do gophers live in http://golang.org?" | xurls
|
|
http://golang.org
|
|
```
