The VTE library inserts terminal capability strings into a tree of tables, and then uses it to determine if data received from a pseudo-terminal is a control sequence or just random data. The sample program "interpret" illustrates more or less what the widget sees after it filters incoming data.
CaptureMock provides capture-replay mocking for Python, on the command line and with client-server communication. CaptureMock's approach is a so-called capture-replay approach. This means that when you 'record' your mock, CaptureMock will observe the interaction between your code and the subsystem you are mocking out, and record it in a text file in its own format. When you then run your test in 'replay mode', CaptureMock can play the role of the subsystem in question, and the real subsystem does not need to even be installed. You can then choose, each time you run your tests, whether you wish to have the real subsystems present and verify/recreate the captured mocks, or to rely on the mocks captured by a previous run. If you are running in 'replay mode' and CaptureMock does not receive the same calls as previously, it will fail the test, and suggest that you may want to recreate the mocks in record mode.
v4l-utils is a collection of various video4linux (V4L) and DVB utilities. libv4l is an accompanying collection of libraries that adds a thin abstraction layer on top of video4linux2 (V4L2) devices. The purpose of this layer is to make it easy for application writers to support a wide variety of devices without having to write separate code for different devices in the same class. It consists of 3 different libraries. libv4lconvert offers functions to convert from any (known) pixel format to V4l2_PIX_FMT_BGR24 or V4l2_PIX_FMT_YUV420. libv4l1 offers the (deprecated) v4l1 API on top of v4l2 devices, independent of the drivers for those devices supporting v4l1 compatibility (which many v4l2 drivers do not). libv4l2 offers the v4l2 API on top of v4l2 devices, while adding support for the application transparent libv4lconvert conversion where necessary.
GluCat is a library of template classes that model the universal Clifford algebras over the field of real numbers, with arbitrary dimension and arbitrary signature. It implements a model of each Clifford algebra corresponding to each non-degenerate quadratic form up to a maximum set by the user. GluCat classes are designed to be used as template parameters for other template libraries. GluCat includes the PyClical extension module for Python. This implements the Python classes index_set and clifford, which interface to corresponding C++ classes in GluCat.
LanguageTool is a style and grammar checker that currently supports English, Polish, German, French, Dutch, and other languages to a different degree. It scans the words and their part-of-speech tags for occurrences of error patterns, which are defined in an XML file. More powerful error rules can be written in Java.
