replaceRE

Replaces all occurrences of a regular expression with the replacement pattern.

Syntax

replaceRE PATTERN REPLACEMENT INPUT
{{ replaceRE "^https?://([^/]+).*" "$1" "http://gohugo.io/docs" }}` → "gohugo.io"
{{ "http://gohugo.io/docs" | replaceRE "^https?://([^/]+).*" "$1" }}` → "gohugo.io"

Hugo uses Go’s Regular Expression package, which is the same general syntax used by Perl, Python, and other languages but with a few minor differences for those coming from a background in PCRE. For a full syntax listing, see the GitHub wiki for re2.

If you are just learning RegEx, or at least Go’s flavor, you can practice pattern matching in the browser at https://regex101.com/.
