{{% note %}} Hugo uses Golang'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 Golang's flavor, you can practice pattern matching in the browser at https://regex101.com/. {{% /note %}}
