var BufferAndStreamOutput = gocmd.Options{
	Buffered:  true,
	Streaming: true,
}

BufferAndStreamOutput sets buffering and streaming of output when running gocmd.Cmd Buffering lets easy inspection of outputs in tests through inspecting gocmd.Cmd.Status.Stdout/err slices

var StreamOutput = gocmd.Options{
	Buffered:  false,
	Streaming: true,
}

StreamOutput sets streaming of output instead of buffering it when running gocmd.Cmd

Functions

func BinaryExists

func BinaryExists(binName, hint string) bool

BinaryExists ensures that binary with given name (binName) is available on the PATH hint lets you customize the error message

func CurrentDir

func CurrentDir() string

CurrentDir returns current directory from where binary is executed

func RedirectStreams

func RedirectStreams(src *gocmd.Cmd, stdoutDest, stderrDest io.Writer, done <-chan gocmd.Status)

RedirectStreams redirects Stdout and Stderr of the gocmd.Cmd process to passed io.Writers

func ShutdownHook

func ShutdownHook(cmd *gocmd.Cmd, done <-chan gocmd.Status)

ShutdownHook will wait for SIGTERM signal and stop the cmd unless done receiving channel passed to it receives status or is closed

func Start

func Start(cmd *gocmd.Cmd, done chan gocmd.Status)

Start starts new process (gocmd) and wait until it's done. Status struct is then propagated back to done channel passed as argument
