Perl Compatible Regular Expressions (PCRE) is a library written in C, which implements a regular expression engine, inspired by the capabilities of the Perl programming language. Philip Hazel started writing PCRE in summer 1997. [ 3 ]
A regular expression (shortened as regex or regexp), [1] sometimes referred to as rational expression, [2] [3] is a sequence of characters that specifies a match pattern in text. Usually such patterns are used by string-searching algorithms for "find" or "find and replace" operations on strings , or for input validation .
Greed, in regular expression context, describes the number of characters which will be matched (often also stated as "consumed") by a variable length portion of a regular expression – a token or group followed by a quantifier, which specifies a number (or range of numbers) of tokens. If the portion of the regular expression is "greedy", it ...
Sorting is case independent and numerically correct. It sorts by the finally displayed text, ignoring link targets, wiki-code, and non-word characters. When used on a single line, it sorts table cells or list items (separated by bullets, dots, dashes, the characters \|/-,;: enclosed in spaces, the characters ,;: followed by spaces, or just ...
The primary regex crate does not allow look-around expressions. There is an Oniguruma binding called onig that does.

Regex – If checked indicates that the find and replace expression is a regular expression. Multiline – If checked, this indicates to AWB that the regex characters "^" and "$" ought to match at the beginning and the end of lines respectively, not just the beginning and end of the entire page. In some programming contexts this is referred to ...
