expect
Package expect is a Go version of the classic TCL Expect.
Usage
example
// spawn `ssh 127.0.0.1` with default timeout=3s
e, err := expect.Spawn("ssh 127.0.0.1", time.Second*3)
if err != nil {
panic(err)
}
// expect for `password:` with default timeout
_, err = e.Expect("password:", -1)
if err != nil {
panic(err)
}
// send string with newline
_, err = e.SendLine("passwd")
if err != nil {
panic(err)
}
// give control to the interactive user
err = e.Interact()
if err != nil {
panic(err)
}
// wait for finish of spawned process
err = e.Wait()
if err != nil {
panic(err)
}

Types ¶
type Expect ¶
type Expect struct {
// contains filtered or unexported fields
}
func (*Expect) Expect ¶
Expect reads spawned processes output looking for pattern. Zero timeout means expect forever. Negative timeout means Default timeout.
func (*Expect) ExpectAny ¶
func (e *Expect) ExpectAny(pattern string, re *regexp.Regexp, timeout time.Duration) (string, error)
ExpectAny is similar to Expect, match string pattern or regexp re.
func (*Expect) Interact ¶
Interact gives control of the child process to the interactive user (the human at the keyboard).
type PipeThrough ¶
type PipeThrough struct {
// contains filtered or unexported fields
}
PipeThrough is a Reader with read deadline. If a timeout is reached, the error is returned. If the provided io.Reader reads error, the error is also returned.
func NewPipeThrough ¶
func NewPipeThrough(reader io.Reader) (*PipeThrough, error)
NewPassthroughPipe returns a new reader for a io.Reader with no read timeout.
func (*PipeThrough) Close ¶
func (pt *PipeThrough) Close() error
func (*PipeThrough) SetReadDeadline ¶
func (pt *PipeThrough) SetReadDeadline(t time.Time) error
