Functions

func CreateRandomLenFile

func CreateRandomLenFile(maxLen int, filesDir string, prefix string) string

func RunCmd

func RunCmd(config CmdConfig) error

Runs an external process and prints its output to stdout / stderr.

Types

type CmdConfig

type CmdConfig interface {
	GetCmd() *exec.Cmd
	GetEnv() map[string]string
	GetStdWriter() io.WriteCloser
	GetErrWriter() io.WriteCloser
}

type CmdOutputPattern

type CmdOutputPattern struct {
	RegExp         *regexp.Regexp
	MatchedResults []string
	Line           string
	ExecFunc       func(pattern *CmdOutputPattern) (string, error)
}

RegExp - The regexp that the line will be searched upon. MatchedResults - The slice result that was found by the regex Line - The output line from the external process ExecFunc - The function to execute

type RandFile

type RandFile struct {
	*os.File
	Info os.FileInfo
}
