The JWT expression parser accepts the most common comparison operatorsas as well as logical operators .

The main purpose of these operators is to construct complex logical comparisons by linking individual expressions.

Please be aware the both operators operands of the respective comparison must have the same data type. The only exceptions are the following:

Automatic casting from Number to Stringfrom
Status
subtle true
title number
to
Status
subtle true
title text
: Whenever you write a numeric term at the right-hand side of a comparison operator like =, and the left-hand side is occupied by a string text term, the parser will automatically transform the right-hand side term into a string text (e.g. "30" = 30 will be interpreted the same way as "30" = "30")
Single values as operator operand in list operations: Operators ~, !~, in and not in can be used for checking a single element (number or string) against a Status

["blue", "red"] ~ "blue"

Operators ~, !~, in and not in when used with a text are useful to look for substrings in another string.

Code Block

language	bash
linenumbers	true

"I love coding" ~ "love"


"I don't like Mondays" !~ "Fridays"


"love" in "I love coding"


"Fridays" not in "I don't like Mondays"

Operators ~, !~, in and not in respect cardinality, i.e., container list must have at least the same number of elements as contained list.

Code Block

language	bash
linenumbers	true

[1, 1] in [1, 1, 1]


[1, 1] not in [1, 2, 3]

Operators = and != , when used for comparing lists, require to have the same elements, with the same cardinality and the same order.

language	bash
linenumbers	true

[1, 2, 3] = [1, 2, 3]


[4, 5, 6] != [4, 6, 5]

Image AddedLogical operators

The table below lists all logical operators that can be used for linking logical terms in an expression.

Logical operators take logical terms (which return

values) as operands and can thus be built using:

a boolean value
a JWT expression parser function returning a boolean value
a comparison
a logical term enclosed by brackets ()
two logical terms connected with a logical operator, where boolean literals and comparisons themselves are logical terms.

A single logical term can be enclosed by brackets () in order to increase the readability of the expressions or to define a precedence which differs from the given one.

Logical operators can also be written in lower case (e.g. and , or )

(IF - THEN -ELSE)

The conditional operator ? : is a powerful operator to construct conditional expressions.

It basically allows you to construct the following expression: IF boolean logical_expression true THEN term_1 ELSE term_2.

title	Order of operations

If you use multiple operators in a single expression, they will follow a certain order in which they are processed or a precedence.

OPERATORS	PRECEDENCE	ASSOCIATIVITY
INTERSECT	1 (highest)	Left-to-right
APPEND, EXCEPT, UNION	2 (lowest)	Left-to-right

UI Text Box

type	tip

When using the list operators, you have to make sure that both lists that you compare are of the same type.
All operators are case insensitive, i.e., they can also be written in lower case: append, union, intersect and except .
There are four equivalent functions available for each type of list, and their behavior is exactly equivalent to that of its corresponding operator.
This way, you can choose to use operators or functions according to your preference. Although operators yield shorter expressions and with fewer parentheses, the usage of functions produces a more functional consistent syntax.
