When writing anything that needs to communicate with a terminal in some way, it is almost always speaking some dialect of VT100 or ANSI. The libvt 100 library aims solely at parsing a stream of VT100/ANSI data and then letting the host application do the rendering. Many other projects also parse VT100/ANSI data, but their parser is always tangled up with the actual rendering of the data, making reuse in other projects problematic. The hope is that other projects will start using libvt100 and everyone can stop reinventing the wheel with each project.
Whiteshoe is a text-based shooter game in which you explore a changing maze and complete your goals before the other players complete theirs or find you. It is based on the old game hunt, but was totally rewritten from scratch to use TCP packets and be more modular and expandable in design.
Slovar performs offline language translations without unnecessary attention grabs. Currently, it operates using translation databases offered by dict.cc and/or ding which must be downloaded by the user first, and flexion databases compiled from Wiktionary. It works on all text terminals with Readline and coloring.
Termdebug is a set of utilities for recording and replaying the input and output of terminal programs. Its main goal is to aid in developing and debugging terminal programs. Other programs such as termrec/termplay, nethack-recorder/player, and script/scriptreplay only record the output. However, when debugging an interactive terminal program, the input is often as important as the output.
