Yacc

yagg, given YACC-like and LEX-like input files, generates a C++ program that generates all strings of a user-specified length. yagg can then be used to generate inputs for testing, or to validate that a grammar accepts the strings that you think it does. The grammar file provides the grammar...

Heirloom Development Tools package provides yacc, lex, m4, make, and SCCS as portable derivatives of the utilities released by Sun as part of OpenSolaris. The OpenSolaris utilities were in turn derived from the original Unix versions, and are assumed be conforming implementations of the POSIX...

Berkeley Yacc is an LALR(1) parser generator. Berkeley Yacc has been made as compatible as possible with AT&T Yacc. Berkeley Yacc can accept any input specification that conforms to the AT&T Yacc documentation. Specifications that take advantage of undocumented features of AT&T Yacc will probably...

ebnf2yacc is a tool to help write yacc parsers/compilers.It takes as input a grammar written in bnf (ebnf support is planned), and outputs a c++ abstract syntax tree that supports the visitor pattern, along with a yacc parser that builds the tree.

PyBison is a Python binding to the Bison (yacc) and Flex (lex) parser-generator utilities. It allows parsers to be quickly and easily developed as Python class declarations, and for these parsers to take advantage of the fast and powerful C-based Bison/Flex. Users write a subclass of a basic...

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 its C interface which provides access to the abstract syntax tree,...

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.

Nasal is a language that I wrote for use in a personal project. Ostensibly it was because I was frustrated with the dearth of small-but-complete embeddable scripting languages, but of course I really wrote it because it was fun. It is still young and incomplete in a few places, but is under...
