Instance Method Details

format(format as Lang.String, parameters as Lang.Array) as Lang.String

Create a formatted String by substituting the given parameters into the given format at the corresponding locations.

Parameters:

• format — (Lang.String) —

  A string using $1$, $2$, $3$... as substitution identifiers

• parameters — (Lang.Array) —

  The Array of content to substitute into the formatted String

Example:

// Set the 'myString' variable to "Your next meeting is at 2:30 on Sep 4 in room 6820."
using Toybox.Lang
var myFormat = "Your next meeting is at $1$:$2$ on $3$ $4$ in room $5$.";
var myParams = [2, 30, "Sep", 4, "6820"];
var myString = Lang.format(myFormat, myParams);

Returns:

• Lang.String —

  A new String with the substituted content
