Functions

func Format

func Format(t *rt.Thread, format string, values []rt.Value) (string, error)

Format is the base for the implementation of lua string.format()

It works by scanning the verbs in the format string and converting the argument corresponding to this verb to the correct type, then calling Go's fmt.Sprintf().

It temporarily requires all the memory needed to store the formatted string, but releases it before returning so the caller should require memory first thing after the call.

func PackSize

func PackSize(format string) (uint, error)

func PackValues

func PackValues(format string, values []rt.Value, budget uint64) (string, uint64, error)

func UnpackString

func UnpackString(format, pack string, j int, budget uint64) (vals []rt.Value, nextPos int, used uint64, err error)
