func main() {
	route, _ := url.Parse("/hello/:name")
	generator := urlgen.New(urlgen.Routes{"hello": route})
	helloUrl, _ := generator.URL("hello", urlgen.Params{"name": "Jane & Jon"})
	fmt.Print(helloUrl.String())
	// Output:
	// /hello/Jane+%26+Jon
}

Using the template helper function to generate URL.

package main

	"html/template"
	"net/url"
	"os"
)

func main() {
	route, _ := url.Parse("/hello/:name")
	generator := urlgen.New(urlgen.Routes{"hello": route})
	helper := urlgen.TemplateFunc(generator)
	markup := `<a href="{{url "hello" "name" "Jane & Jon"}}">Hello</a>`
	tmpl := template.Must(template.New("foo").Funcs(template.FuncMap{"url": helper}).Parse(markup))
