In CoyoteScript, just like in most other script and programming languages, logical operators and comparison operators are used to create expressions, which are used to check whether or not certain conditions are met. If a condition is met, we refer to the result as “true”, and if it is not met, we refer to it as “false”.
Comparison Operators
Comparison operators are used to describe what relationship between 2 values is required for the condition to be met. In CoyoteScript, these are:
- “==” The values on either side of the operator have to be identical.
- “!=” The values on either side of the operator must be different from eachother.
- “>” The value on the left of the operator has to be greater than the value on the right. This is only applicable for numerical values.
- “>=” The value on the left has to be greater than or equal to the value on the right. This is only applicable for numerical values.
- “<” The value on the left has to be smaller than the value on the right. This is only applicable for numerical values.
- “<=” The value on the left has to be smaller than or equal to the value on the right. This is only applicable for numerical values.
- “contains” The value on the left has to contain the value on the right. This is only applicable for strings, lists, and maps. For strings, the value on the right has to be a substring of the value on the left. For lists, the value on the right has to be an item in the list. For maps, the value on the right has to be a key inside of the map.
- “!contains” The value on the left can not contain the value on the right. This is the inverse of “contains” and works for the same types.
For example:
- “hello == hey” would resolve to “false”.
- “hello != hey” would resolve to “true”.
- “8 > 3” would resolve to “true”.
- “5 <= 4” would resolve to “false”.
- “(1, 2, 3, 4) contains 1” would resolve to “true”.
Logical Operators
Logical operators are used to resolve multiple conditions into a single expression. In CoyoteScript, these are:
- “&&” The conditions on either side of the operator both need to resolve to “true” for the combined result to be “true”.
- “||” Only one of the conditions on either side has to be “true” for the combined result to be “true”.
For example:
- “hello == hello && 7 > 2” would resolve to “true” as both conditions would resolve to “true”.
- “hello = hey || 5 <= 9” would resolve to “true” because one of the conditions would resolve to “true”.
The order in which the conditions in the expression are resolved can be controlled with parenthesis. Conditions inside parenthesis will be resolved first, and multiple parenthesis can be nested inside another, just like in mathematical operations.
For example:
“hello != hi && (7 < 2 || 8 > 4)” would resolve to “true”.
