Format
text(FormatText,Args)
Returns
The text with macros arguments substituted.
Args
FormatText: a text string possibly containing text macros.Args: a set of arguments that corresponds to the number of empty embedded expressions in FormatText.
Complicated or lengthy embedded expressions in a text string can sometimes make the string difficult to read. In this case, one can use trailing arguments. The position in which the expression should be substituted should be marked with [] and the expression should then be passed as an argument after the text string.
usr << text("You are [] leagues from home.",sqrt(usr.x**2 + usr.y**2))
