Regular expression
Regular expressions, also referred to as regex or regexp, provide a concise and flexible means for matching strings of text, such as particular characters, words, or patterns of characters.
Source: http://en.wikipedia.org/wiki/Regex
They are used by the wikidot parser, in general, but you can use them in data forms or in mailform module for entry validation.
Examples:
- /^(19[5-9][0-9]|20[01][0-9])$/ will match any year from 1950 to 2019
- /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/ will match any valid email address
