This module exists just for the sake of compatibility w/ version 0.16 and below. new Just a stub. list2re Simply does: Regexp::Asssemble->new->add(@list);...

Returns a regular expression that will match any string from the input list @strings. First argument can be a reference to a hash, which controls how the regexp is built. Valid keys are: type => pcre|posix|emacs Controls the flavor of the generated e...

Regexp::Match::List matches a string to a list of regular expressions with callbacks and sorting optimization for large datasets. Think Regexp::Match::Any with optimization (sort on usage trends, most popular first -- see Data::Sorting) and expanded ...

Please consult the manual of Regexp::Common for a general description of the works of this interface. Do not use this module directly, but load it via *Regexp::Common*. $RE{list}{-pat}{-sep}{-lastsep} Returns a pattern matching a list of (at least tw...

One very useful ability of Perl is to do relatively cheap transliteration via the tr/// regex operator. Unfortunately, Perl requires tr/// to be known at compile-time. The common solution has been to put an eval around any dynamic tr/// operations, b...

Regexp::Log is a base class for a variety of modules that generate regular expressions for performing the usual data munging tasks on log files that cannot be simply split(). The goal of this module family is to compute regular expressions based on t...

Pure-perl module for: * Parsing POSIX Extended Regular Expressions ($ere) into Non-Deterministic Finite Automata ($nfa) * Manipulating $nfas (concatenating, or-ing, and-ing) * Computing Deterministic Finite Automata ($dfas) from $nfas (powerset const...

This module is for searching inside DNA or RNA or protein sequences. The sequence to be found is specified by a restricted version of regular expressions. The restrictions allow us to manipulate the regexp in various ways described below. As well as ...

"Regexp::Copy" allows you to copy the contents of one Regexp object to another. A problem that I have found with the qr// operator is that the Regexp objects that it creates are is impossible to dereference. This causes problems if you want to change...

This module provides the following functions: "is_regexp($ref)" Returns a boolean indicating whether $ref is a regexp reference. Is not tricked by blessed regexps. "regexp_seen_evals($re)" Returns true if $re contains embedded Perl code. "regexp_is_f...

The purpose of the PPIx-Regexp package is to parse regular expressions in a manner similar to the way the PPI package parses Perl. This class forms the root of the parse tree, playing a role similar to PPI::Document. This package shares with PPI the ...

This module is intended to test your regular expressions. Given a subject string and a regular expression (aka pattern), the module not only tests whether the regular expression complete matches the subject string, it performs a "utf8::upgrade" or "u...

Regexp::Lexer is a lexer for regular expression of perl. This module splits the regular expression string to tokens which has minimum meaning....

Objects in this class represent individual SV variables found in the arena during a heap dump. Actual types of SV are represented by subclasses, which are documented below....

This module uses the regex engine to generate the strings that a given regex would match. Some ideas for uses: Test and debug your regex. Generate test data. Generate combinations. Generate data according to a lexical pattern (urls, etc) Edit the reg...

Markup languages, like HTML, are difficult to parse. The reason is that you can have a line like: <font size=+1>H</font>ello <font size=+1>W</font>orld How can we find the string "Hello World", in the above line, and replace it by "Hello Universe" (w...

By default, this module exports a single hash (%RE) that stores or generates commonly needed regular expressions (see "List of available patterns"). There is an alternative, subroutine-based syntax described in "Subroutine-based interface". General s...

"Regexp::Fields" adds the extended "(?<name> ...)" pattern to Perl's regular expression language. This works like an ordinary pair of capturing parens, but after a match you can use $&{name} instead of $1 (or whichever $N) to get at the captured subs...
