Parameters processing

Parameter type	Attribute	Allowed data type	Example (basic pattern: [parameter_key_name:attribute=value:attribute=value:...])
All	WhenEmpty	string which can contain (system) parameters	[key_name:WhenEmpty="User [user_name] left the value empty"]
Common to String, Number, Date, Time	Format	text1	[text:Format=uppercase:Culture=ru-KZ], [number:Format=C:Culture=rm-CH]
Common to String, Number, Date, Time	Culture	text2	[date_param:Format=yy:Culture=rof-TZ], [time_param:Format=HH-mm:Culture=ps-AF]
Boolean	WhenTrue/False	string which can contain (system) parameters	[invoice_paid:WhenTrue="User set the value to true"]
Date	TimeZone	available time zones list	[current_time:TimeZone=UTC-08], [current_time:HH-mm-ss:TimeZone=E. Europe Standard Time]
	UtcOffset	text3
	AddYears	number	[current_date:yyyy:AddYears=4]
	AddMonths	number	[current_date:MM:AddMonths=-1]
	AddDays	number	[current_date:dd:AddDays=-4]
	AddHours	number	[current_date:hh:AddHours=5]
Number	Padding	number > 0	[invoice_number:Padding=5], entered invoice_number value is 2, result of the operation is 00002
Number	LeadingZeros	alias for padding
[regex] or [regular_expression]	IgnoreCase	true or false	[regex:Input=[text_parameter]:Pattern=(\\d+)_(.+):Output=$2_$1] in case that text_parameter equals 12345_invoice then the result will be invoice_12345.
	Pattern*	text
	Input*	string which can contain (system) parameters
	Output	text
	WhenNotMatched	string which can contain (system) parameters
	WhenEmpty	string which can contain (system) parameters
[remove_accents] or [remove_diacritics]	Input*	string which can contain (system) parameters	[remove_accents:Input=[user_full_name]]
[substring]	Start	Either Start, StartBefore or StartAfter must be defined Either Length, EndBefore or EndAfter must be defined In case the Start value is negative given number of characters is evaluated from the end of the string, the same applies to Length	[substring:Input=[user_full_name]:Start=3], if the user's full name is "Martin King" the result of such operation will be "tin King". [substring:Input=[email_of_user]:StartAfter=@:EndBefore=.] this particular example will extract substring from email between '@' and the '.' it is to say domain name or company name.
	StartBefore
	StartAfter
