Sam is a multi-file text editor based on structural regular expressions.It was originally designed in the early 1980s at Bell Labs by Rob Pike with the help of Ken Thompson and other Unix developers for the Blit windowing terminal running on v9 Unix; [1] it was later ported to other systems.
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]
In 2011 Lifehacker described Notepad++ as "The Best Programming Text Editor for Windows", stating that "if you prefer a simple, lightweight, and extensible programming plain-text editor, our first choice is the free, open-source Notepad++". [21] Lifehacker criticized its user interface, stating that "It is, in fact, fairly ugly. Luckily you can ...
As of Perl 5.10, PCRE is also available as a replacement for Perl's default regular-expression engine through the re::engine::PCRE module. The library can be built on Unix, Windows, and several other environments.
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 .
