+// Package analytics provides a standard way to store the Google Analytics
+// tracking ID.
+//
+// Usage Example
+//
+// This analytics package provides a convenient way to configure an analytics
+// ID for an app.  To use, just call analytics.ID(c) and inject that ID
+// into a template.
+//
+//   import (
+//               ...
+//     "github.com/luci/luci-go/server/analytics"
+//     ...
+//   )
+//
+//   func myHandler(c context.Context, rw http.ResponseWriter, r *http.Request, p httprouter.Params) {
+//     ...
+//     return templates.Args{
+//                 "AnalyticsID": analytics.ID(c),

add also

func Snippet(c context.Context) template.HTML {
  id := ID(c)
  if id == "" {
     return ""
  }
  sanitized := <check id against regexp or properly escape it>
  return template.HTML(fmt.Sprintf(`(function(......`, sanitized))
}

To avoid copy-pasting stuff in HTML templates.

(template.HTML is an alias for string, but it is not auto-escaped when rendered,
see https://golang.org/pkg/html/template/#HTML)

Done.

+//     }
+//   }
+//
+// And in the base html:
+//
+// {{ if .AnalyticsID }}
+// (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
+// (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
+// m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
+// })(window,document,'script','https://www.google-analytics.com/analytics.js','ga');
+//
+// ga('create', '{{.AnalyticsID}}', 'auto');
+// ga('send', 'pageview');
+// {{ end }}
