AffirmIt! is a supportive testing framework for Ruby. It tolerates all code, whether it exhibits behavioral challenges or not. It never uses the words "test" or "failure", which would imply a value judgment, or "assertions," which would imply an absolute truth. Instead, it treads softly around code and espouses preferences.
PyGUI is a GUI API which is designed specifically for Python, taking advantage of Python's unique language features and working smoothly with Python's data types on the three major platforms (Unix, Macintosh, and Windows) that are small and lightweight, interposing as little code as possible between the Python application and the platform's underlying GUI facilities, and not bloating the Python installations or applications which use them.
fifoirc creates a named pipe on the local filesystem, such that any data written to the pipe will be written to an IRC channel. It is also possible to connect a filter program to the channel, such that any text written in the channel is passed to the program, and any text output by the program is passed to the channel.
The PDM library aids in inspecting and managing Python programs running as daemons, allowing client programs to connect to the daemon process in order to interact with it in various ways. Primarily, it provides an interactive read-eval-print loop, and a non-interactive programmatic interface not entirely unlike Java's JMX.
MMLi is a simple Music Macro Language interpreter written in ISO C99. The Music Macro Language originated in 8-bit BASIC implementations (as part of the “PLAY” command), and can still be found in modern BASICs (like QB64) and in system software (like FreeBSD's spkr.c driver.) This interpreter features an example "mmlitest" program which can be used to translate MML sequences into beep(1) commandline arguments.
