Functions

func Self

func Self(envVariableParts ...string) error

Self - replaces executable with dlv running the executable and listening on a port

envVariableParts - variadic list of 'pieces' to be transformed into the
                   env variable indicating where dlv should listen.
                   Default: If no envVariableParts are provided, env variable
                            defaults to []string{Dlv,Listen,path.Base(os.Args[0])}
                            which is DLV_PORT_<name of executable>
