If the length of two params is larger than x, only display one param

I am trying to make Hugo limit my meta titles length. What I am trying to do is: if
{{- with .Title }}{{ . }} | {{ end }}{{ .Site.Title -}}{{ end }}
is larger than 70 chars , then only display:
{{- with .Title }}{{ . }}{{ end }}

What is the correct way of writing the math so Hugo adds {{.Title}} + | + {{.Site.Title}}?

The rest I think would be something like:
{{if gt (len “Math goes here”) 70}}
{{- with .Title }}{{ . }}{{ end }}
{{else}}
{{- with .Title }}{{ . }} | {{ end }}{{ .Site.Title -}}{{ end }}
{{end}}

Checkout the substr function

I am not sure how to apply this, as it has to combine the length of the two strings, not just one of them.

Hi,

You could try something like this:

{{ $title := "" }}

{{ with .Title }}
  {{ $title = printf "%s | " . }}
{{ end }}

{{ $title = printf "%s%s" $title .Site.Title }}

{{ if gt ( len $title ) 70 }}
  {{ with .Title }}{{.}}{{ end }}
{{ else }}
  {{ $title }}
{{ end }}
