Function htmlEscape

internal/outbound/forward.go:286–291

htmlEscape is a tiny subset of html.EscapeString — sufficient for the four characters that can break a blockquote. Avoids pulling in html/template for one function.

(s string)

// the four characters that can break a blockquote. Avoids pulling in
// html/template for one function.
func htmlEscape(s string) string {
	if !strings.ContainsAny(s, "&<>\"") {
		return s
	}
	return strings.NewReplacer("&", "&amp;", "<", "&lt;", ">", "&gt;", "\"", "&quot;").Replace(s)
}
