Extract urls from text using regular expressions.
|
|
|
|
go get -u github.com/mvdan/xurls
|
|
|
|
```go
|
|
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:
