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.
String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.
Lua semantics have been increasingly influenced by Scheme over time, [6] especially with the introduction of anonymous functions and full lexical scoping. Several features were added in new Lua versions. Versions of Lua prior to version 5.0 were released under a license similar to the BSD license.
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.
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.
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 ...
