JavaCC
JavaCC (Java Compiler Compiler) is an open source parser generator and lexical analyzer generator written in the Java programming language. JavaCC is similar to yacc in that it generates a parser from a formal grammar written in EBNF notation. Unlike yacc, however, JavaCC generates top-down parsers. JavaCC can resolve choices based on the next ''k'' input tokens, and so can handle LL(''k'') grammars automatically; by use of "lookahead specifications", it can also resolve choices requiring unbounded look ahead. JavaCC also generates lexical analyzers in a fashion similar to lex. The tree builder that accompanies it, JJTree, constructs its trees from the bottom up. JavaCC is licensed under a BSD license. ==History== In 1996, Sun Microsystems released a parser generator called ''Jack''. The developers responsible for ''Jack'' created their own company called Metamata and changed the ''Jack'' name to JavaCC. Metamata eventually became part of WebGain. After WebGain shut down its operations, JavaCC was moved to its current home.
