Syntax

	log($message)

log($message, $arguments)

Description

Writes an entry to the application log.

Parameters

Name	Type	Description	Mandatory	Default
message	String	The message to be written to the log. If arguments is also specified, placeholders in the form of {0}...{n} can be defined in the message. If the message contains a placeholder but there is no argument to fill it, {n} is written to the message in plain text.	yes
arguments	Set	Arguments to be inserted into the placeholders of message in the specified order. If no or too few placeholders are specified, then not all arguments will be used.	no

Examples

Simple log message

	log('Hello');

Output (in log): Hello

Placeholder Log Message

	log('Current date: {0}. Current week day: {1}', today(), today().toUserCalendar().dayOfWeek())

Output (in log): Current date: 14.02.22 16:00. Current week day: 2

Placeholder with too few arguments

log('Current date: {0}. Current week day: {1}')

Output (in log): Current date: {0}. Current week day: {1}.

Since no arguments were specified, the placeholders are not replaced and output like this.

Placeholder with too many arguments

log('Current date: {0}', today(), today().toUserCalendar().dayOfWeek())

Output (in log): Current date: 14.02.22 16:00

There are more arguments than placeholders, so the second argument is ignored.
