func EnterRawTerminalMode ¶ Uses

func EnterRawTerminalMode(ctx *context.T) string

EnterRawTerminalMode uses stty to enter the terminal into raw mode; stdin is unbuffered, local echo of input characters is disabled, and special signal characters are disabled. Returns a string which may be passed to RestoreTerminalSettings to restore to the original terminal settings.

func Forward ¶ Uses

func Forward(conn net.Conn, s sender, r receiver) error

Forward forwards data read from net.Conn to a TunnelForwardClientStream or a TunnelForwardServerStream.

func RestoreTerminalSettings ¶ Uses

func RestoreTerminalSettings(ctx *context.T, saved string)

RestoreTerminalSettings uses stty to restore the terminal to the original settings, taking the saved settings returned by EnterRawTerminalMode.

func SetWindowSize ¶ Uses

func SetWindowSize(fd uintptr, ws Winsize) error

SetWindowSize sets the terminal's window size.

type Winsize ¶ Uses

type Winsize struct {
    Row    uint16
    Col    uint16
    Xpixel uint16
}

Winsize defines the window size used by ioctl TIOCGWINSZ and TIOCSWINSZ.

func GetWindowSize ¶ Uses

func GetWindowSize() (*Winsize, error)

GetWindowSize gets the terminal's window size.
