Variables

var (
	// LineLength is the maximum length allowed of a printed line of text. This is
	// the primary control for this package. It defaults to the greater of the
	// current terminal width (detected at init time) and MaxLineLength.
	LineLength = initialLineLength

	// MaxLineLength sets the upper bound for how long a line can be. This is a
	// secondary control that adjusts how LineLength is calculated. It defaults to
	// 120 (for readability).
	MaxLineLength = 120
