Ox is an attribute grammar compiling system that augments Lex and Yacc specifications with definitions of synthesized and inherited attributes written in a combination of Ox and C/C++ syntax. From these augmented specifications, Ox generates ordinary Lex and Yacc specifications that build and decorate attributed parse trees. The user can specify parse-tree traversals for easy ordering of side effects such as code generation.

ULS is a class library for creating lexical analyzer from language specification file. It's provided as C/C++/C# and Java (class) libraries with a few of tools on Linux/Windows platform.

SCons is a software construction tool that is a superior alternative to the classic "Make" build tool that we all know and love. SCons is implemented as a Python script and set of modules, and SCons "configuration files" are actually executed as Python scripts. This gives SCons many powerful capabilities not found in other software build tools. We make SCons available in three distinct packages, for different purposes. - The scons package is the basic package to install SCons. You...

A C++ high-performance regex library and Flex-compatible lexical analyzer generator with full Unicode support, new indentation anchors, lazy quantifiers, and many other modern features. 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...

...The tools are: •xmlSchemaParser - parses and reformats XML schema files, and prints typederivation hierarchies. Also includes a C++ model of XML schema. •xmlInstanceParserGenerator - generates C++ classes and a YACC/Lex instance file parser from an XML schema – it’s a software tool that writes software tools •orphanFinder - identifies unused types and undefined types in one or a set of XML schema files •xmlSchemaAttributeConverter - rewrites an XML schema file, converting attributes to elements •xmlSchemaXpathChecker - checks that all paths in all constraints in a schema are possible, and reports those that do not exist •xmlSchemaPathFinder - generates all possible paths through an instance tree that contain components specified by the user

pyparsing is a general parsing module for Python. Grammars are implemented directly in the client code using parsing objects, instead of externally, as with lex/yacc-type tools. Includes simple examples for parsing SQL, CORBA IDL, and 4-function math

NLT is free, open-source C# lexer and GLR parser suite -- which translates to ability to parse ambiguous grammars. Grammar can be defined directly in code or (preferably) in separate file (lex/yacc-like) for included generator. If you understand/guess the meaning of grammar in C#: // scanning lexer.AddStringRule(")", match => SymbolEnum.RPAREN); // parsing prod_builder.AddProduction(SymbolEnum.exp, SymbolEnum.LPAREN, SymbolEnum.exp, SymbolEnum.RPAREN, (_1, e, _3) => (AstNode)e); or grammar in NLT format: // scanning /[A-Za-z_][A-Za-z_0-9]*/ -> IDENTIFIER, IdentifierSymbol.Create($text); // parsing program -> list:namespace_list { new Program(currCoords(), (Namespaces)list) }; you should be able to use it :-). ...

...As any major interpreted language, you can easily create bindings of your C library functions to Frost. Its interpreter is written in C, and it only uses libC and POSIX system calls (Lex and Yacc are not required). You can easily compile it on Linux or OS X using the included Makefile.

...The class library supports symbol tables, Unicode text manipulation, reserved word mappings, and translating between Unicode and byte oriented encodings. Tombo is an alternative for lex, yacc and Bison tools. Source can be browsed in git/code repository or src directory. Send e-mail to tombo@gekkoware.com for support

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.

Ply is a version of Lex&yacc ,we define IDL specification,guid you how to create your business interface, tce2py is a part of enginee components,it can be create idl->python mapping code, integrated it into your project ,enjoying your life! that's easy,flex

Parse C Windows Use Yacc & Lex

The project is for developing libraries for visualizing biological sequence data on the web. The libraries are written in C and currently use a language (lex/yacc) based front end for presenting features on genomes, contigs, or any type of sequence.

Generate parsers with ease, using a graphical user interface, or console. Design your parsers graphically or by using standard regular expressions and BNF syntax similar to lex/yacc. Generated parsers can be in C or C++.

PyJacc (Python's Just Another Compiler Compiler) is an open source lexer and parser (similar to lex and yacc). PyJacc provides the ability to create powerful lexing and parsing libraries in high level languages such as Python, PHP, and C#.

The first ever "complete" suite of open-source programming languages for Indian vernaculars. It includes equivalents of C, C++, lex, yacc, assembly, BASIC, LOGO etc. in Hindi, Bangla, Gujrati, Assamese, Nepali and other Indian languages.

PLY is a set of bash scripts that provides parsing functionality for macros that generate shell code. It was inspired by lex & yacc UNIX utilities used for compiler construction, and its function is analogous to the role of C preprocessor.

wsbasic a basic interpreter or scripting language implemented without flex/bison or lex/yacc. Object oriented and very maintainable code. Based on jack crenshaw's let's build a compiler. Can act as a replacement for bash or sh scripting.

Given YACC-like and LEX-like input files, yagg generates a C++ program that generates all strings of a user-specified length. yagg is easy to use, and provides a means of generating test inputs or validating a parser grammar by inspecting the strings.

Wtparser is a lex/yacc-based parser for wikitext as defined by mediawiki.

cl-calc aims to be a simple command line calculator. It can handle precedence unlike a lot of graphical calculators. cl-calc is written in Python and requires PLY (Python-Lex-Yacc).

SDL_GLel is an OpenGL extension library for SDL. Its files are dymically generated from the OpenGL extension repository using a lex/yacc parser, in order to be up-to-date with new extensions.

A generic XML parser generator. With a DTD input for any ML language, the C parser for that language is generated. The users can embed their C code with a minimal knowledge of lex/yacc.

In a nutshell it takes as input the formal specification of any text protocol in ABNF and generates the parser in C language for that grammar using lex/yacc.

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.
