Regular expressions (or regex) are a common and very versatile programming technique for manipulating strings. On Wikipedia you can use a limited version of regex called a Lua pattern to select and modify bits of text from a string. The pattern is a piece of code describing what you are looking for in the string.
This module is intended to provide access to basic string functions. Most of the functions provided here can be invoked with named parameters, unnamed parameters, or a mixture. If named parameters are used, Mediawiki will automatically remove any leading or trailing whitespace from the
The string-search functions in Lua script can run extremely fast, comparing millions of characters per second. For example, a search of a 40,000-character article text, for 99 separate words (passed as 99 parameters in a template), ran within one second of Lua CPU clock time.
This module is subject to page protection.It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing.
Note: Lua patterns are not regular expressions in the traditional POSIX sense, and they are not even a subset of regular expressions. But they share many constructs with regular expressions (more below). Lua patterns are used to define, find and handle a pattern in a string. It can do the common search and replace action in a text, but it has ...

Wrap the string in quotes; quotes can be chosen for a specific language. Will not quote an empty string, and will not quote if there is a quote at the start or end of the (trimmed) string. 1 Input text (will be automatically trimmed); may be empty. 2
