JavaCC: Difference between revisions

I had a good look at the linked reference, and it looks very much that the "benchmark" indeed cannot be cited here because it is troubled by serious methodical flaws. We cannot just cite arbitrary DZone articles, there must be a certain level of quality to them. |

JavaCC (Java Compiler Compiler) is an open-source parser generator and lexical analyzer generator written in the Java programming language.[2]
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.
