RE2/J
linear time regular expression matching in Java
RE2/J is a high-performance regular expression engine implemented in pure Java as a port of Google’s C++ RE2 library. Unlike traditional regex engines such as Java’s java.util.regex, PCRE, or Perl’s implementation—which rely on backtracking and can suffer from catastrophic exponential runtimes—RE2/J guarantees linear-time matching relative to input size. It achieves this efficiency by simulating all possible matches in a single pass using a nondeterministic finite automaton (NFA), ensuring predictable and safe performance even with complex patterns. ... -

re2
Alternative to backtracking regular expression engines
RE2 is a fast, safe, thread-friendly alternative to backtracking regular expression engines like those used in PCRE, Perl, and Python. It is a C++ library. This is the source code repository for RE2, a regular expression library. There is a fair amount of documentation (including code snippets) in the re2.h header file. Unless otherwise noted, the RE2 source files are distributed under the BSD-style license found in the LICENSE file. -

soulng
Lexer and parser generator tool for C++
The SoulNG project contains two tools: a lexical analyzer generator slg and a parser generator spg. The generators and the produced lexical analyzers and parsers use four C++ libraries that are also included in the project. The slg tool takes a .lexer file that contains the description of a lexical analyzer as input and produces C++ source code for a lexical analyzer as output. The produced lexical analyzer is a finite state machine that recognizes patterns described as regular expressions and return corresponding token identifiers to the parser. ... -

JSVerbalExpressions
JavaScript Regular expressions made easy
...This method will not be accessible from outside the source file since VerEx() returns an instance of the class rather than the class itself. sanitize is a static method on the VerbalExpression class. However, it is also exposed as VerEx().sanitize. Enabling control multi-line matching would cause the expression to not look for matches beyond the first line. -

twitter-text
This code is used at Twitter to tokenize and parse text
...This includes emoji which have been modified by Fitzpatrick skin tone or gender modifiers, even if they are composed of significantly more Unicode code points. Emoji weight is defined by a regular expression in twitter-text that looks for sequences of standard emoji combined with one or more Unicode Zero Width Joiners (U+200D). -

pegplusplus
A PEG parser library for C++
This library implements PEG (Parsing Expression Grammar) parsers, which can be embedded in a C++ program. The grammars are built and interpreted at run time, without an intermediate code generation stage. It tries to mimic as closely as possible the functionality and style of Ian Piumarta's LEG compiler. LEG grammars can be translated easily and almost mechanically. Actions and semantic predicates can be written directly in the grammar, using lambdas. C++11 or later is required. -

libvcr
A C++ library for managing configuration files via regular expressions
This library is supposed to be used in your C++ programs for managing simple Unix configuration files like /etc/hosts. The library allows to create default configuration, read the configuration file, validate each found option or value with C++ std::regex, automatically remove incorrect options and even merge several configurations with predefined priorities for each option. So it may be useful in programs which use several configuration files. For an extra example of the library usage see... -
