Styx is a scanner/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 it's C interface, preservation of full source information, pretty printing to faciliate source-source translation, and persistence to aid rapid interpreter writing. It also supports reentrancy. Styx works well under several different OSes, including serveral Unixes, DOS, and Windows.

Release Notes: The regular expression syntax and scanner were extended to handle language facilities such as heredoc strings as well as ambiguities (n character lookahead). Two helper programs based on graphviz were added for grammar visualisation. The documentation was improved by adding further example grammars. Minor bugfixes were made to the preprocessing facility and scanner diagnoses.
