    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]

  3. Raku rules - Wikipedia

    en.wikipedia.org/wiki/Raku_rules

    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.

  5. Perl language structure - Wikipedia

    en.wikipedia.org/wiki/Perl_language_structure

    The Perl language includes a specialized syntax for writing regular expressions (RE, or regexes), and the interpreter contains an engine for matching strings to regular expressions. The regular-expression engine uses a backtracking algorithm, extending its capabilities from simple pattern matching to string capture and substitution. The regular ...

    en.wikipedia.org/wiki/Talk:Perl_Compatible...

    The name is a misnomer, because Perl's regular expressions permit embedded Perl code during matching and replacing, so to be truly "Perl Compatible" would need a full Perl interpreter embedded in the library. PCRE contains no such interpreter. Um...it's not a misnomer. The regular expressions of PCRE are compatible with Perl's. Embedded source ...

    sed – (stream editor), is a Unix utility that parses and transforms text, using a simple, compact programming language. sed was one of the earliest tools to support regular expressions, and remains in use for text processing, most notably with the substitution command. Other options for doing "stream editing" include AWK and Perl.

    The Raku design process was first announced on 19 July 2000, on the fourth day of that year's Perl Conference, [10] by Larry Wall in his State of the Onion 2000 talk. [11] At that time, the primary goals were to remove "historical warts" from the language; "easy things should stay easy, hard things should get easier, and impossible things should get hard"; and a general cleanup of the internal ...
