Different syntaxes for writing regular expressions have existed since the 1980s, one being the POSIX standard and another, widely used, being the Perl syntax. Regular expressions are used in search engines, in search and replace dialogs of word processors and text editors, in text processing utilities such as sed and AWK, and in lexical ...
Perl interpreters have been developed for most operating systems (platforms), taking into account the idiosyncrasies of each, so all such platforms can theoretically run the same code. Text manipulation – anything from spell checking, to search and replace operations using regex, to natural language processing.
The structure of the Perl programming language encompasses both the syntactical rules of the language and the general ways in which programs are organized. Perl's design philosophy is expressed in the commonly cited motto "there's more than one way to do it".
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 ]
As of 2010, the standard module is generally regarded as deprecated; [2] often recommended libraries are pcre (with full support for PCRE) and re (which is not as complete but claims better performance and provides frontends to popular syntaxes: PCRE, Perl, Posix, Emacs, shell globbing).

In Pro Perl, Peter Wainwright makes a punning reference to the Logrus and the Pattern in an example of regular expression usage. In the example, a search-and-replace operation is being executed. The text to search for is specified as a regular expression pattern. The sample text to replace the pattern with is logrus. [16]

Raku rules are the regular expression, string matching and general-purpose parsing facility of the Raku programming language, and are a core part of the language. Since Perl's pattern-matching constructs have exceeded the capabilities of formal regular expressions for some time, Raku documentation refers to them exclusively as regexes, distancing the term from the formal definition.
