VT 100 was a video terminal, but modern terminal programs implement many of the special control codes that it supported. This allows text displayed in a terminal to be manipulated beyond simply printing. This includes rewriting previous lines of text, adding colors, or adding special effects. Carter Turn VT100 is a class that allows you to easily take advantage of terminals supporting VT100 codes to create loading bars, ASCII art that refreshes itself, and special text. Carter Turn VT100 is available at Github.
