Functions

func DisableEcho

func DisableEcho(fd uintptr, state *State) error

GetFdInfo returns the file descriptor for an os.File and indicates whether the file represents a terminal.

func IsTerminal

func IsTerminal(fd uintptr) bool

IsTerminal returns true if the given file descriptor is a terminal.

func RestoreTerminal

func RestoreTerminal(fd uintptr, state *State) error

RestoreTerminal restores the terminal connected to the given file descriptor to a previous state.

func SetWinsize

func SetWinsize(fd uintptr, ws *Winsize) error

SetWinsize tries to set the specified window size for the specified file descriptor.

func StdStreams

func StdStreams() (stdIn io.ReadCloser, stdOut, stdErr io.Writer)

Types

type State

type State struct {
	// contains filtered or unexported fields
}

State represents the state of the terminal.

func MakeRaw

type Winsize

type Winsize struct {
	Height uint16
	Width  uint16
	// contains filtered or unexported fields
}

Winsize represents the size of the terminal window.

func GetWinsize

func GetWinsize(fd uintptr) (*Winsize, error)
