Message format

Syntax

	messageFormat($pattern)

Constructs a message format with the specified pattern for either parse() or format() calls.

MessageName	Type	Type Description	Mandatory	Default
pattern	Character string	The pattern in which formatting is to take place. Placeholders can be defined (`{0}`, `{1}` etc.), which are then filled with parameters during formatting. These placeholders can also define format types and subformat types in order to additionally format the parameters (`{0, number, integer}`, `{1, date}` etc.). For more information on possible patterns, see MessageFormat.	yes

Type: Subject object

A message format that can now be used for parse() or format() calls.

	messageFormat("Good {0}, {1}! Today we have {2} degrees.").format("Morning", "Sir", 19)

Output: "Good Morning Sir! Today we have 19 degrees."

With fill() applied directly to the format string, the same formatting can be achieved without explicitly creating a format.

"Good {0}, {1}! Today we have {2} degrees."fill("Morning", "Sir", 19)

Output: "Good Morning Sir! Today we have 19 degrees."

	messageFormat("At {1,time} on {1,date}, there was {2} on planet {0,number,integer}.").format(7, now(), "a disturbance in the Force")

Output: "At 15:36:40 on 11.10.2021, there was a disturbance in the Force on planet 7."

The date is used several times in this message and formatted accordingly using time and date.

	messageFormat("Good {0}!").parse("Good Morning!")

Output: List of parse results, here ["Morning"].
