Byline simplifies writing interactive command-line applications by building upon [ansi-terminal][] and [haskeline][]. This makes it possible to print messages and prompts that include terminal escape sequences such as colors that are automatically disabled when standard input is a file. It also means that Byline works on both POSIX-compatible systems and on Windows.
The primary features of Byline include printing messages, prompting for input, and generating custom menus. It was inspired by the [highline] Ruby library and the [terminal library][] by Craig Roche.
