VariableCondition

Inherits

Condition

Variable conditions compare the value of a variable against another value using a specific operator.

Format:

[!]$variable operator value

An exclamation mark placed before $ will negate the condition.

For variables of type bool, operator and value may be omitted. $variable and !$variable conditions are equivalent to $variable == true and $variable == false respectively.

The value can be:

  • a value of the same type as variable (automatically converted to lists when necessary, no need to put single values in []),

  • a variable of the same type as variable,

  • a list of values of the same types as variable, may be empty ([]).

See Condition for examples.
