Coco/S is a compiler generator that takes plain EBNF grammar files and features a SAX style call back API. It is written in Java and produces a Java Scanner (Lexer) and Parser for the language described by the input grammar.
Coco/S is a branch of the 2010/11 release of Coco/R for Java.
While Coco/R takes an attributed grammar file, Coco/S has a callback API. This has the advantage of a clean separation between grammar (EBNF) and Compiler/Interpreter.
Common Text Transformation Library of C++ classes and functions to parse and modify STL strings. CTTL substring classes may be compared, inserted, replaced, and parsed with EBNF grammars. Compiled program implements recursive descent LL(INF) parser.
PRECCX is an infinite-lookahead higher-order compiler-compiler for context-dependent grammars. The generated code is ANSI C and ANSI C++; the code will compile and run under either C or C++. PRECCX grammars admit EBNF + inherited and synthetic attributes
K-automaton is a new parsing (syntactic analysis) machine isomorphous to language. Implemented in Java. Can generate Java code from grammars described in EBNF.

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.
