Functions

func Run

func Run(userInput io.Reader, toIvy io.Writer, output io.Writer) error

Run runs the demo. The arguments are the user's input, a Writer used to deliver text to an ivy interpreter, and a Writer for the output. It assumes that ivy is writing to the same output. Ivy expressions are read from a file (maintained in demo.ivy but embedded in the package). When the user hits a blank line, the next line from the file is delivered to ivy. If the user's input line has text, that is delivered instead and the file does not advance. A nil userInput ignores the user and just runs the script.

func Text

func Text() string

Text returns the input text for the standard demo.
