In Haskell, data type declarations, Parsec parsers, and HughesPJ pretty-printers very much resemble each other; supplying all three is virtuous, but involves a large amount of code duplication. syntran is a code generator designed to reduce the amount of duplication. Its source is similar to a Parsec LanguageDef-using parser, annotated with the unique information from the data type declaration and the pretty-printer which would normally not be found in a parser. It separates this information out to generate pure Haskell.
cstor is a cross-reference compiler and reverse engineering tool. It compiles one text file (database) from multiple source modules (currently reads C, C++, and Perl). The tool combines reverse engineering capabilities, code validation, and an HTML documentation generator. The database can then be reused from own scripts and programs, e.g. to implement cross-compilers, validate coding conventions, build statistics etc. The builtin documentation generators are actually an application of the database.
Quality Objects (QuO) is a framework for providing quality of service (QoS) in network-centric distributed applications. These applications range from embedded applications to wide area network applications, including many military and commercial applications. QuO bridges the gap between the socket-level QoS being specified, researched, and provided by a number of organizations and the distributed object level where many distributed applications are best written. QuO adds QoS to CORBA and Java RMI in a manner which is appropriate for creating applications that can adapt to environments that are unpredictable or have strict resource constraints.
