RemoveUnusedDeclaration

Removes the declaration for a constant, variable, procedure, or line label that isn't used. This operation can break the code if the declaration is actually in use but Rubberduck couldn't find where.


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

This quickfix addresses the selected inspection result, but can also be applied to all similar inspection results in the following scopes (as a single operation):

  • Procedure
  • Module
  • Project

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.

Module1 (before)

Option Explicit
Public Sub DoSomething()
    Const value = 42
    Debug.Print 42
End Sub

Module1 (after)

Option Explicit
Public Sub DoSomething()
    Debug.Print 42
End Sub
