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

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++.

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.

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).

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.

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
