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)

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

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.
