// Copyright 2013-2015 Bowery, Inc.
// Package prompt implements a cross platform line-editing prompt. It also
// provides routines to use ANSI escape sequences across platforms for
// terminal connected io.Readers/io.Writers.
//
// If os.Stdin isn't connected to a terminal or (on Unix)if the terminal
// doesn't support the ANSI escape sequences needed a fallback prompt is
// provided that doesn't do line-editing. Unix terminals that are not supported
// will have the TERM environment variable set to either "dumb" or "cons25".
//
// The keyboard shortcuts are similar to those found in the Readline library:
//
// - Enter / CTRL+D
// - End the line.
// - CTRL+C
// - End the line, return error `ErrCTRLC`.
// - Backspace
// - Remove the character to the left.
// - CTRL+L
// - Clear the screen(keeping the current lines content).
// - Home / End
// - Jump to the beginning/end of the line.
// - Up arrow / Down arrow
// - Go back and forward in the history.
// - Left arrow / Right arrow
// - Move left/right one character.
// - Delete
// - Remove the character to the right.
