re2
Alternative to backtracking regular expression engines
...In POSIX mode, RE2 accepts standard POSIX (egrep) syntax regular expressions. In Perl mode, RE2 accepts most Perl operators. The only excluded ones are those that require backtracking (and its potential for exponential runtime) to implement. These include backreferences (submatching is still okay) and generalized assertions. The Syntax page documents the supported Perl-mode syntax in detail. -

soulng
Lexer and parser generator tool for C++
...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. The spg tool takes .parser files that contain descriptions of parsers as input and produces C++ source code for parser classes as output. The parser generator produces a recursive descent top-down backtracking parser that use the lexical analyzer generated by slg to tokenize the input. -

mgrep - A Multiline grep Implementation
mgrep - A Multiline grep Implementation
mgrep is a command line tool that allows users to search text files for lines matching a given regular expression. It is similar to the well-known Unix utility, grep. As a natural extension to the single-line regular expressions, mgrep is also capable of searching for multiline patterns. mgrep is not a grep replacement, but it is intended to be grep-compatible: implemented options and behavior should be the same as those of grep. -

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... -

flex: the fast lexical analyser
flex is a tool for generating scanners
...The flex program reads user-specified input files, or its standard input if no file names are given, for a description of a scanner to generate. The description is in the form of pairs of regular expressions and C code, called rules. Flex generates a C source file named, "lex.yy.c", which defines the function yylex(). The file "lex.yy.c" can be compiled and linked to produce an executable. When the executable is run, it analyzes its input for occurrences of text matching the regular expressions for each rule. Whenever it finds a match, it executes the corresponding C code. -

hbcxx
Use "#!/usr/bin/env hbcxx" to make C++ source code executable
...This is not because the language has been changed massively but because the new features encourage a different, and slightly higher level way to think about writing C++. It's faster, more fun, supports lambdas, has tools to simplify memory management and includes regular expressions in the standard library. hbcxx is a tool to keep things fast and fun by putting of the moment you have to write a build system and an install script. For simple programs, especially for quick and dirty personal toys, the day you have to write a proper build system may never come. Instead just copy your C++ source code into $HOME/bin. ... -

qtFlexC++ is a tool for generating scanners: programs which recognized lexical patterns in text. qtFlexC++ reads the given input files for a description of a scanner to generate. The description is in the form of pairs of regular expressions and C++ code, called rules. qtFlexC++ generates as output a C++ source and include file, `lexyy.cpp` and `lexyy.h`, which defines a class `lexyy'. This file is compiled with your code to produce an executable. When the executable is run, it analyzes its input for occurrences of the regular expressions. Whenever it finds one, it executes the corresponding C++ code.

cmd-test
Utility to test console applications
This console application helps in testing other console applications by checking the output against specific rules specified by the user as regular expressions. The application expects as arguments one or more control files that consist of commands. Each line is interpreted and compared against a list of known commands. Comments must stay on their own line and should start with a # sign. The documentation uses the term target to refer to a program that is being tested. ... -

Topal: Organic Parsing Language
Syntactic script interpreter
...It's designed for parsing (as opposed to lexing) with a focus on usability. The language uses procedures rather than functions. Procedures can contain conditional expressions and very basic data storage / bitwise operations. Additionally you can import DLL files and run their functions within the procedures. Procedure names and their argument names are not static; they are defined via a regular expression pattern. For the interpreter to work, it requires two inputs: the desired data for parsing and processing, and an OPL file containing the rules and actions for said input parsing and processing. ... -
