Types

type Options

type Options struct {
	// Prompt controls what's shown at the beginning of the line. If not
	// specified, this defaults to "> "
	Prompt string
	// Prelude is some text that's printed before control is given to the user.
	// By default this is empty. If specified, this will be printed with a
	// newline following it.
	Prelude string
	// Autocomplete controls whether this REPL session has autocompletion
	// enabled. The way autocomplete is implemented can incur a performance
	// penalty, so it's turned off by default.
	Autocomplete bool
}

Options contains parameters for configuring a REPL session.
