Avoid Concatenating Adjacent String Literals

Overview

Avoid concatenating string literals.

ATC Finding Message: Fold literal string concatenation into one literal

Rationale

Joining two or more literals with && produces one constant value at runtime, so the operator adds no information and only fragments the text. Folding the literals makes the final string visible and removes a pointless expression. Keep && only when at least one operand is dynamic.

Non-Compliant

lv_path = 'orders' && '/' && 'open'.

Compliant

lv_path = 'orders/open'.
