badgeHandler serves a Go SVG badge image for requests to /badge/<path> and a badge generation tool page for requests to /badge/[?path=<path>].

func (s *Server) badgeHandler(w http.ResponseWriter, r *http.Request) {
	path := strings.TrimPrefix(r.URL.Path, "/badge/")
	if path != "" {
		http.ServeFile(w, r, fmt.Sprintf("%s/img/badge.svg", s.staticPath))
		return
	}

The user may input a fully qualified URL (https://pkg.go.dev/net/http or https://github.com/my/module) or just a pathname (net/http).

	path = strings.TrimPrefix(r.URL.Query().Get("path"), "https://pkg.go.dev/")
	urlSchemeIdx := strings.Index(path, "://")
	if urlSchemeIdx > -1 {
		path = path[urlSchemeIdx+3:]
	}

	page := badgePage{
		basePage:  s.newBasePage(r, "Badge generation tool"),
		LinkPath:  path,
		BadgePath: "badge/" + path + ".svg",
	}
	s.servePage(r.Context(), w, "badge.tmpl", page)
