Expandable Collection User Defined Function

Usage

    aMap := data.NewMap();
    aMap.Put("ts", "2015-02-11")
    udf.Register(aMap)
    expanded := aMap.ExpandAsText(`$FormatTime($ts, "yyyy")`)
 

The list of defined UDFs:

• Length, Len returns length of slice, map or string

• AsData - convert source into a map or slice, it accepts data structure, or JSON, YAML literal
• AsInt - convert source into a an int
• AsFloat - convert source into a a float
• AsBool - convert source into a boolean
• FormatTime, takes two arguments, date or now, followed by java style date format
• Values - returns map values
• Keys - return map keys
• IndexOf - returns index of matched slice element
• Join - join slice element with supplied separator
