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.

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 :-). ...

The T-lex package contains two pipelines. The T-lex pipeline calls presence/absence of known TE insertions using re-sequencing data. On top of the genotyping, this pipeline also allows to re-annotate TEs and discover traces of transposition events called Target Site Duplication (TSD). The other T-lex pipeline discovers and annotates de novo TE insertions.

...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.

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.

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++.

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.

manipulation of text based documents by using the stdin/stdout stream designed to complement sed, lex and awk. It has no help except for the readme file and the example.

sedlexlist is a stream editor in that it reads from stdin and writes to stdout, similar to sed, lex and awk. The difference is this, sedlexlist works with lists of words and is designed to compliment the other tools.

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 small but extensible Java based "embedded lisp"- derives from the 1960 Mc Carthy Lisp a new consequently functional, dynamically scoped dialect enriched by modern features (pattern matching, parallel processing, implicit lex. closures etc).

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.

Php Lexer - converts .lex files into .php files (so you can tokenize files) used to be: a PHP compiler for the .NET CIL (but that's pretty dead now)

LEX is a filemanager written in C++/Qt for Linux, using the classical Windows Explorer layout (a treeview with a tableview)

Chaperon is a LALR(1) parser, which parse structured text documents and generate XML documents as output. It includes a parser generator like yacc and a regex scaner like lex. As input use Chaperon a grammar written in XML.

The Dirt virtual machine is designed to be easily used as a scripting engine or runtime core in C or C++ projects. The language itself is very similar to C. The tools have been created from scratch (no lex/bison/yacc) and are very portable

This project is a parser generator, like the lex and yacc, but is based on the JavaCC grammar. It was writing in c++, run on linux and dos, and don't use another library. The grammar parser is specified through a simple file, and the parser generated
