C3PO is a software synthesis tool that provides a solution for building maintainable, reliable and robust software infrastructures and/or compiler frontends from a set of attributed grammar rules in EBNF notation.
DParser is a scannerless GLR parser generator based on the Tomita algorithm. It is self-hosted and very easy to use. Grammars are written in a natural style of EBNF and regular expressions and support both speculative and final actions.
... visualizes EBNF (Extended Backus Naur Form). Therefore an .ebnf File is required, which contains rules written in EBNF. The program parses the rules, visualizes them as syntax diagrams and is able to generate .gif and .emf files for further use.
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.
Ell is pure-header library to write EBNF grammars as C++ code. It eases the development of parsers or similar applications, while removing the need to write a lexer. Ell is not a tool to generate parsers (like ANTLR) : the grammar you write is directly embedded into your C++ code. The core library is light, headers-only and written using generation templates technique to achieve a fastest execution. The service provided by Ell is very similar to what Boost Spirit provides, but with a simpler obj
