Oniguruma (鬼車) is a free and open-source regular expression library that supports a variety of character encodings written by K. Kosako. The Ruby programming language, in version 1.9, as well as PHP 's multi-byte string module (since PHP5), use Oniguruma as their regular expression engine. [2] It is also used in products such as Atom, [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.
RE2 (software) RE2 is a software library which implements a regular expression engine via finite-state machines using automata theory, in contrast to almost all other regular expression libraries, which use backtracking implementations. It provides a C++ interface. RE2 was implemented and used by Google.
Website. pcre.org. 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] PCRE's syntax is much more powerful and flexible than either of the POSIX regular expression ...
WP:AWBREGEX. A regular expression or regex is a sequence of characters that define a pattern to be searched for in a text. Each occurrence of the pattern may then be automatically replaced with another string, which may include parts of the identified pattern. AutoWikiBrowser uses the .NET flavor of regex. [1]
A regex search scans the text of each page on Wikipedia in real time, character by character, to find pages that match a specific sequence or pattern of characters. Unlike keyword searching, regex searching is by default case-sensitive, does not ignore punctuation, and operates directly on the page source (MediaWiki markup) rather than on the ...
RE/flex (regex-centric, fast lexical analyzer) [1] [2] is a free and open source computer program written in C++ that generates fast lexical analyzers (also known as "scanners" or "lexers") [3] [4] in C++. RE/flex offers full Unicode support, indentation anchors, word boundaries, lazy quantifiers (non-greedy, lazy repeats), and performance ...
