# pty
Pty is a Go package for using unix pseudo-terminals.
## Install
```sh
go get github.com/creack/pty
```
## Examples
Note that those examples are for demonstration purpose only, to showcase how to use the library. They are not meant to be used in any kind of production environment.
### Command
```go
package main
import (
"io"
"os"
"os/exec"
"github.com/creack/pty"
)
func main() {
c := exec.Command("grep", "--color=auto", "bar")
f, err := pty.Start(c)
if err != nil {
panic(err)
}
go func() {
f.Write([]byte("foo\n"))
f.Write([]byte("bar\n"))
f.Write([]byte("baz\n"))
f.Write([]byte{4}) // EOT
}()
io.Copy(os.Stdout, f)
}
```
### Shell
```go
package main
import (
"io"
"log"
"os"
"os/exec"
"os/signal"
"syscall"
"github.com/creack/pty"
"golang.org/x/term"
)
func test() error {
// Create arbitrary command.
c := exec.Command("bash")
// Start the command with a pty.
ptmx, err := pty.Start(c)
if err != nil {
return err
}
// Make sure to close the pty at the end.
defer func() { _ = ptmx.Close() }() // Best effort.
// Handle pty size.
ch := make(chan os.Signal, 1)
signal.Notify(ch, syscall.SIGWINCH)
go func() {
for range ch {
if err := pty.InheritSize(os.Stdin, ptmx); err != nil {
log.Printf("error resizing pty: %s", err)
}
}
}()

// Set stdin in raw mode.

if err != nil {
panic(err)
}

// NOTE: The goroutine will keep reading until the next keystroke before returning.
