+`strings.ReplaceRE` returns a copy of `INPUT`, replacing all matches of the regular
+expression `PATTERN` with the replacement text `REPLACEMENT`.
+The number of replacements can be limited with an optional `LIMIT` parameter.

{{ replaceRE "^https?://([^/]+).*" "$1" "http://gohugo.io/docs" }}` → "gohugo.io"
{{ "http://gohugo.io/docs" | replaceRE "^https?://([^/]+).*" "$1" }}` → "gohugo.io"
+{{ replaceRE "a+b" "X" "aabbaabbab" 1 }} → "Xbaabbab"
