Libswoc (https://github.com/solidwallofcode/libswoc), "Solid Wall Of C++" library, is a collection of C++ utility classes. They are based on existing ATS core classes, except for Lexicon. Documentation is available here - http://docs.solidwallofcode.com/libswoc.
The correspondence is swoc_meta ts_meta BufferWriter BufferWriter Errata Errata IntrusiveDList IntrusiveDList IntrusiveHashMap IntrusiveHashMap MemSpan MemSpan MemArena MemArena Scalar Scalar swoc_file ts_file TextView TextView IPSpace IPMap Lexicon * A major issue is these have undergone roughly 2 years of intensive development and therefore can be significantly different from the ATS versions. In particular, IPSpace is a far more general IP address based container than IPMap. TextView, Errata, and BufferWriter are much improved and no longer source compatible (TextView especially as I took the opportunity to organize and structure the method names). Libswoc is also used by a couple of Yahoo! internal projects and may need to be maintained as a distinct library for that reason. My recommendation is to treat libswoc the same way as libyaml-cpp. Drop it in to the source tree, update the version as needed. Libswoc development has wound down - the goal was to provide an updated version of some basic ATS utilities and that's done. There's a bit more work to do on BufferWriter but that's all internal (no API changes). Over time I would replace use of the existing core classes with the updated version. In some cases, such as MemSpan, this will be trivial. For others, such as TextView, it will be a bit more challenging. I hope to use Lexicon in a number of places - it is a bidirectional container of integral values to string views, designed to support translating between enumerations and names. This will help clean up some of the ugliness in the configuration parsing. I would also note the quality of the documentation for these core utilities is somewhat better than for the current core classes.
