PCRE

The PCRE (Perl Compatible Regular Expressions) library is a set of functions that implement regular expression pattern matching using the same syntax and semantics as Perl 5. PCRE has its own native API, as well as a set of wrapper functions that correspond to the POSIX regular expression API. The ... [More] PCRE library is free, even for building commercial software.

ack

ack is a tool like grep, aimed at programmers with large trees of heterogeneous source code. ack is written purely in Perl, and takes advantage of the power of Perl's regular expressions. * Searches recursively through directories by default, while ignoring .svn, CVS and other VCS ... [More] directories. * ack ignores most of the crap you don't want to search * Lets you specify file types to search, as in --perl or --nohtml. * Color highlighting of search results. * Uses real Perl regular expressions, not a GNU subset. * ack is pure Perl, so consistent across all platforms. It even comes as a single standalone program with no module dependencies. [Less]

Apache ORO

claimed by Apache Software Foundation

The Jakarta-ORO Java classes are a set of text-processing Java classes that provide Perl5 compatible regular expressions, AWK-like regular expressions, glob expressions, and utility classes for performing substitutions, splits, filtering filenames, etc. This library is the successor to the ... [More] OROMatcher, AwkTools, PerlTools, and TextTools libraries originally from ORO, Inc. [Less]

Regexp::Assemble

Regexp::Assemble takes an arbitrary number of regular expressions and assembles them into a single regular expression (or RE) that matches all that the individual REs match. As a result, instead of having a large list of expressions to loop over, a target string only needs to be tested against ... [More] one expression. This is interesting when you have several thousand patterns to deal with. Serious effort is made to produce the smallest pattern possible. It is also possible to track the original patterns, so that you can determine which, among the source patterns that form the assembled pattern, was the one that caused the match to occur. [Less]

File::Stream

A Perl module to allow Perl regular expressions to be applied to streams. Quoting the documentation: Perl filehandles are streams, but sometimes they just aren't powerful enough. This module offers to have streams from filehandles searched with regexes and allows the global input record ... [More] separator variable to contain regexes. Thus, readline() and the <> operator can now return records delimited by regular expression matches. [Less]

pcre-light

A small, efficient and portable regex library for Perl 5 compatible regular expressions in Haskell. The PCRE library is a set of functions that implement regular expression pattern matching using the same syntax and semantics as Perl 5. Test coverage data for this library is available at: ...

visre

A simple and straight-forward program to help visualize perl regular expressions.

re::engine::Lua

With Perl 5.10, regular expression engines become pluggable. This module re::engine::Lua supplies the Lua regular expression dialect.

re::engine::LPEG

With Perl 5.10, regular expression engines become pluggable. This module re::engine::LPEG supplies the Lua Parsing Expression Grammar.
