Re2c is a tool for writing very fast and very flexible scanners. Unlike any other such tool, re2c focuses on generating high efficient code for regular expression matching. As a result this allows a much broader range of use than any traditional lexer.

...Accepts Flex lexer specification syntax and is compatible with Bison/Yacc parsers. Generates reusable source code that is easy to understand. Supports fast scanning of UTF-8/16/32 files, strings, and streams. The reflex scanner generator generates clean C++ lexer class code that is thread-safe. Generates Graphviz files to visualize state machine DFAs. RE/flex works seamlessly with Bison.

flex is a tool for generating scanners. A scanner, sometimes called a tokenizer, is a program which recognizes lexical patterns in text. 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().

Flexc++ has moved to GitHub, and can now be reached at https://fbb-git.github.io/flexcpp/ Please refer to github's location for the latest archive and releases.

qtBisonC++ is a general-purpose parser generator that converts a grammar description for an LALR(1) context-free grammar into a QT C++ program to parse that grammar. qtBisonC++ reads the given input files for a description of a scanner to generate. The description is in the form of grammar in Backus-Naur Form (BNF), called rules. qtBisonC++ 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 analyses its input to verify that its correspond to the grammar.

...Long term goals include a robust grammar file syntax, output suitable for multiple programming languages, and tools for better integrating compiler functionality, parse tree manipulation, and FSM based scanner generation.

Kayacc is an alternate name for the TOMBO project. I am in the process of updating the Tombo project page with version 2.1.0. Please download Tombo2.1.0.tar.gz from the Files tab. Tombo is a compiler generation toolkit for constructing compilers and interpreters. It includes a BNF compiler that generates parsers for context free grammars, and a class library to support compiler development. The class library supports symbol tables, Unicode text manipulation, reserved word mappings,...

Styx is a scanner and parser generator designed to address some shortcomings of the traditional lex/yacc combination. It has unique features like automatic derivation of depth grammar, production of the derivation tree including it's C interface which provides access to the abstract syntax tree, preservation of full source information and pretty printing to facilitate source-source translation, persistence to aid rapid interpreter writing.

...Please use the following GitHub project page from now on: https://github.com/twain/wia-on-twain A WIA on TWAIN driver implementation designed to expose all necessary scanner functionality while adhering to the WIA 1.0 and WIA 2.0 specification and achieving compatibility with all WIA compliant applications.

re2clexer is a wrapper around the scanner generator re2c. It simplifies the creation of re2c based lexers by performing the task of buffer management.

ELR Parser/scanner generator with lexical conflict resolution

Implementation of a combined scanner and parser generator for object oriented C++ or Java code generation

CppCC is an object-oriented scanner and LL(k) parser generator. It aims to replace LEX&YACC for those who write C++ applications that involve parsing.

This project is to create a lexical scanner generator. It generates C++ STL compatible, thread safe, scanner classes.

YooParse stands for Yet-another Object-Oriented Parser code generator. It is the complement of YooLex, a lexer code generator. The purpose of YooParse is to generate a parser that integrates tightly with the scanner generated by YooLex.

SimpleCompiler is a suite of tools for generating compilers and code generators. A simple BNF style language is used to describe scanner and parser in a UTF-8 source file. The output is described with a template language that is used to add formatting to the parse tree. Code is generated that automatically traverses the parse tree and calls a method on a transformer object to modify the parse tree. Each node is visited in document order, and a method is called at the beginning and end of each node visit. ...
