Refactoring is a process of improving your source code without creating a new functionality. Refactoring helps you keep your code solid , dry, and easy to maintain.
Invoke refactoring
Select an item to refactor. You can select a file/folder in the Project tool window or expression/symbol in the editor.
Press Ctrl+Alt+Shift+T to open a list of refactorings that can be selected. Alternatively, you can use a keyboard shortcut for a specific refactoring.
If you need to undo your refactoring, pressCtrl+Z.
Preview refactoring changes
For some refactorings, CLion lets you preview changes before applying them.
To see potential changes (the list of usages where the refactoring will be performed), click Preview in the Refactoring Preview dialog.
Check the changes that are going to be made in the Find tool window. You can exclude Delete or remove Ctrl+X changes that you consider unnecessary.
Click Do Refactor to proceed with the changes.
Resolve conflicts
When CLion encounters problems with your refactoring, it opens a dialog with the list of conflicts and their brief descriptions.
Click Continue to ignore the problem and proceed to open the preview in the Find tool window.
Click Show Conflicts in View to open the conflict entries in the Find tool window and deal with them further.
For example, you can try to exclude an entry from refactoring by pressing Delete or click Cancel and return to the editor.
Configure refactoring settings
In the Settings/Preferences dialog Ctrl+Alt+S, select Editor | General.
On the General page, in the Refactorings section, adjust the refactoring options and click OK.
