Package template converts strings to postfix expressions. In some respects it is separate from tapestry; the postfix expressions themselves require translation into tapestry commands.

Types

type Expression

type Expression = postfix.Expression

Expression provides a local alias for postfix.Expression; a series of postfix.Function records.

func Parse

func Parse(template string) (ret Expression, err error)

Parse the passed template string into an expression.

func ParseExpression

func ParseExpression(str string) (ret Expression, err error)

ParseExpression reads a series of simple operand and operator phrases and creates a series of postfix.Function records. ex. "(5+6)*(1+2)" -> 5 6 ADD 1 2 ADD MUL where MUL and ADD are types.Operator, while the numbers are types.Number.
