VT100 codes

Variables

var Out io.Writer

Out is an io.Writer which can be used to write to the terminal eg for use with fmt.Fprintf(terminal.Out, "terminal fun: %d\n", n)

Functions

func GetSize

func GetSize() (w, h int)

GetSize reads the dimensions of the current terminal or returns a sensible default

func Start

func Start()

Start the terminal - must be called before use

func Write

func Write(out []byte)

Write sends out to the VT100 terminal. It will initialise the terminal if this is the first call.

func WriteString

func WriteString(s string)

WriteString writes the string passed in to the terminal
