FalseCondition

A detector that highlights conditions that evaluate to a constant true or false in if, while, or until statements, and zero iterations in repeat statements.

Why is it bad?

Conditions that always evaluate to a constant true or false are likely the result of a typo or logic error. Such conditions can lead to unintended behavior, dead code, or incorrect control flow. This detector helps identify these cases so they can be corrected, improving the code's reliability.

Example

const FALSE: Bool = false;
// Bad: Always false because of operator precedence
if ((param | value) & FALSE) {
// ... never executed
}

Use instead:

const FALSE: Bool = false;
// OK: Fixed after the analyzer highlighted this
if (param) {}
