Boolean logic in Rewst workflows

Boolean values and their role in automation

Boolean values represent simple yes/no conditions, like on/off or true/false. They define rules and logic in workflows by evaluating conditions.

Boolean values are fundamental in automation workflows, controlling decision-making and process flow. Understanding Boolean logic helps ensure that workflows are efficient, reliable, and easy to maintain.

Key Boolean concepts

Boolean values: Represent true or false, similar to 1 (on) and 0 (off).
Logical operators: and, or, not determine conditions in workflows.
Comparison operations: Evaluate conditions (e.g., user_role == "admin").
Custom conditions in workflows: Enable transitions based on Boolean evaluations.

Boolean operators in Rewst workflows

Boolean logic controls workflow decisions using these key operators:

and – Requires both conditions to be true.
- Example: user_logged_in and is_admin
or – Requires at least one condition to be true.
- Example: is_manager or is_admin
not – Inverts a Boolean value.
- Example: not user_logged_in (returns true if user_logged_in is false).

Boolean logic in action

True and false = false – Both conditions must be true for and to return true.
True or false = true – Only one condition needs to be true for or to return true.
Not false = true – Flips the Boolean value to its opposite.

Best practices for Boolean logic in Rewst

To ensure efficiency and maintainability, follow these best practices.

Structuring logical conditions

Group logic with parentheses: Ensures conditions execute in the correct order.
- Example: (is_admin and is_active) or is_super_admin
Use in for cleaner conditions:
- Before: if role == "admin" or role == "super_admin"
- After: if role in ["admin", "super_admin"]

Simplifying Boolean expressions

Use ternary operators for concise logic:
- Syntax: variable = value_if_true if condition else value_if_false
- Example: status = "Active" if is_active else "Inactive"
Leverage short-circuit evaluation:
- Skips unnecessary checks by placing the most likely condition first.
- Example: if user_logged_in and is_admin: (Skips is_admin check if user_logged_in is false.)
