External Links | Sabancı University

External links uses patterns (regular expressions) to match the "href" property of links.

Here are some common patterns.

(example\.com) Matches example.com.
(example\.com)|(example\.net) Multiple patterns can be strung together by using a pipe. Matches example.com OR example.net.
(links/goto/[0-9]+/[0-9]+) Matches links that go through the Links module redirect.

Common special characters:

. Matches any character.
? The previous character or set is optional.
\d Matches any digit (0-9).
[a-z] Brackets may be used to match a custom set of characters. This matches any alphabetic letter.

All special characters (^ $ . ? ( ) | * +) must also be escaped with backslashes. Patterns are not case-sensitive. Any pattern supported by JavaScript may be used.
