BaseX is a light-weight, high-performance, and scalable XML database system and XPath/XQuery processor, including full support for the W3C Update and Full Text extensions. An interactive and user-friendly GUI frontend gives you great insight into large XML data instances. It is platform independent and works out of the box.
libcsv_parser++ is a C++ library for parsing text files to extract records and fields. The records can be delimited with any set of characters. It makes the following assumptions: the record terminator is only one character in length; the field terminator is only one character in length; and the fields are enclosed by single characters, if any. The parser can handle documents where fields are always enclosed, not enclosed at all, or optionally enclosed. When fields are strictly all enclosed, there is an assumption that any enclosure characters within the field are escaped by placing a backslash in front of the enclosure character. The software could be ported to Windows with very little effort.
The psycogreen package makes it possible for psycopg2 to work with coroutine libraries, using asynchronous calls internally but offering a blocking interface so that regular code can run unmodified. While Psycopg offers coroutine support, the main module is a C extension that cannot be monkey-patched to become coroutine-friendly. Instead it exposes a hook that coroutine libraries can use to install a function integrating with their event scheduler. Psycopg will call the function whenever it executes a libpq call that may block. psycogreen is a collection of "wait callbacks" that can be used to integrate Psycopg with different coroutine libraries. psycogreen is currently mainly useful for integration with gevent.
