BooleanAssignedInIfElse

Identifies conditional assignments to mutually exclusive Boolean literal values in conditional branches.


New This feature is currently only available in pre-release builds (or the xmldoc asset doesn’t yet exist on main!).

Inspection type: MaintainabilityAndReadabilityIssues

Default severity: Warning

Reasoning

The assignment could be made directly to the result of the conditional Boolean expression instead

Quick-Fixes

The following quick-fixes are available for this inspection:

  • IgnoreOnce: Adds an '@Ignore annotation to ignore a specific inspection result. Applicable to all inspections whose results can be annotated in a module.
  • IgnoreInModule: Adds an '@IgnoreModule annotation to ignore a inspection results for a specific inspection inside a whole module. Applicable to all inspections whose results can be annotated in a module.
  • ReplaceIfElseWithConditionalStatement: Simplifies conditional Boolean literal assignments with a direct assignment to the conditional expression.

Examples

Each example is a self-contained MCVE showing the feature in a single specific scenario.

Standard Module
Named Module1 by default, these are general-purpose standard procedural modules.
Class Module
Named Class1 by default, these modules define the default interface for an object of that type.
Predeclared Class
A class module with its VB_PredeclaredId attribute set to True (with or without a @PredeclaredId annotation).
Interface Module
Abstract interfaces are class modules (with or without an @Interface annotation) whose default interface is not a class type intended to be instantiated.
UserForm Module
A predeclared class with a design-time visual designer using the MSForms UI framework.
Document Module
Owned by the host application, these class modules belong to the host document and may handle various events fired by the host application.

The following code should trigger this inspection:

MyModule

Public Sub DoSomething(ByVal value As Long)
    Dim result As Boolean
    If value > 10 Then
        result = True
    Else
        result = False
    End If
    Debug.Print result
End Sub
