Types

type Cmder 

type Cmder struct{}

Cmder handles running subprograms synchronously and asynchronously.

func NewCmder 

func NewCmder() *Cmder

func (*Cmder) Run 

func (c *Cmder) Run(cmd ExecCmd) (output string, err error)

Run runs a command in a blocking manner, returning its output and an error if it failed.

func (*Cmder) Start 

func (c *Cmder) Start(cmd ExecCmd) (
	stdoutLines, stderrLines chan string, waitError chan error, err error)

Start launches a command and streams stdout and stderr to channels. All the channels returned should be closed when an error, nil or not, is received in the waitError channel. The channels should NOT be closed if an error is returned directly with err, as they will already be closed internally by the function.

type ExecCmd 

type ExecCmd interface {
	CombinedOutput() ([]byte, error)
	StdoutPipe() (io.ReadCloser, error)
	StderrPipe() (io.ReadCloser, error)
	Start() error
	Wait() error
}

ExecCmd is the interface for exec.Cmd.
