Functions

func Find 

func Find(text string) (string, bool)

Find the internal function name for an operator, if the input text is one.

func FindReverse 

func FindReverse(op string) (string, bool)

FindReverse returns the unmangled, text representation of the operator.

func FindReverseBinaryOperator 

func FindReverseBinaryOperator(op string) (string, bool)

FindReverseBinaryOperator returns the unmangled, text representation of a binary operator.

func Precedence 

func Precedence(op string) int

Precedence returns the operator precedence, where the higher the number indicates higher precedence operations.
