Shelve and unshelve changes
Shelving is temporarily storing pending changes you have not committed yet. This is useful, for example, if you need to switch to another task, and you want to set your changes aside to work on them later.
With CLion, you can shelve both separate files and entire changelists.
Once shelved, a change can be applied as many times as you need.
In the Commit tool window Alt+0, right-click the files or the changelist you want to put to a shelf and select Shelve changes from the context menu.
In the Shelve Changes dialog, review the list of modified files.
In the Commit Message field, enter the name of the shelf to be created and click the Shelve Changes button.
You can also shelve changes silently, without displaying the Shelve Changes dialog. To do this, select a file or a changelist you want to shelve, and click the Shelve Silently icon on the toolbar, or press Ctrl+Shift+H. The name of the changelist containing the changes you want to shelve will be used as the shelf name.
To avoid ending up with numerous shelves with the same name (such as Default, for example), you can drag a file or a changelist from the Commit to <branch> tab to the Shelf tab of the Commit tool window, wait a second until it's activated, and edit the new shelf name on-the-fly when you release the mouse button.
Unshelving is moving postponed changes from a shelf to a pending changelist. Unshelved changes can be filtered out from view or removed from the shelf.
In the Shelf tab, select the changelist or the files you want to unshelve.
Press Ctrl+Shift+U or choose Unshelve from the context menu of the selection.
In the Unshelve Changes dialog, specify the changelist you want to restore the unshelved changes to in the Name field. You can select an existing changelist from the list or enter the name for a new changelist to be created containing the unshelved changes. You can enter the description of the new changelist in the Comment field (optional).
If you want to make the new changelist active, select Set active. Otherwise, the current active changelist remains active.
If you want CLion to preserve the context of a task associated with the new changelist on its deactivation and restore the context when the changelist becomes active, select the Track context option (see tasks and contexts for details).
If you want to remove the changes you are about to unshelve, select the Remove successfully applied files from the shelf option. The unshelved files will be removed from this shelf and added to another changelist and marked as applied. They will not be removed completely until deleted explicitly by clicking on the toolbar, or selecting Clean Already Unshelved from the context menu.
Click OK. If conflicts occur between the patched version and the current version, resolve them as described in Resolve conflicts.
You can also unshelve changes silently, without displaying the Unshelve Changes dialog. To do this, select a file or a changelist you want to unshelve, and click the Unshelve Silently icon on the toolbar, or press Ctrl+Alt+U. The unshelved files will be moved to the active pending changelist.
You can also drag a file or a changelist from the Shelf tab to the Commit to <branch> tab to unshelve it silently. If you drag it holding the Ctrl key, it will be copied to the Commit to branch tab instead of being removed from the shelf.
Discard shelved changes
In the Shelf view, select the changelist that contains the changes you do not want to keep any more.
Right-click it and choose Delete from the context menu, or press Delete.
Restore unshelved changes
CLion lets you reapply unshelved changes if necessary. All unshelved changes can be reused until they are removed explicitly by clicking the icon on the toolbar, or selecting Clean Already Unshelved from the context menu.
Make sure that the Show Already Unshelved toolbar option is enabled.
Select the files or the shelf you want to restore.
From the context menu of the selection, choose Restore.
Apply external patches
You can import patches created inside or outside CLion and apply them as shelved changes.
In the Shelf view, choose Import Patches from the context menu.
In the dialog that opens, select the patch file to apply. The selected patch appears in the Shelf tab as a shelf.
Select the newly added shelf with the patch and choose Unshelve Changes from the context menu of the selection.
Automatically shelve base revision
It may be useful to configure CLion to always shelve base revisions of files that are under Git version control.
Press Ctrl+Alt+S to open the IDE settings and select.
Select the Shelve base revisions of files under distributed version control systems option.
If this option is enabled, the base revision of files will be saved to a shelf that will be used during a 3-way merge if applying a shelf leads to conflicts. If it is disabled, CLion will look for the base revision in the project history, which may take a while; moreover, the revision that the conflicting shelf was based on may be missing (for example, if the history was changed as a result of the rebase operation).
Change the default shelf location
By default, the shelf directory is located under your project directory. However, you may want to change the default shelf location. This can be useful, for example, if you want to avoid deleting shelves accidentally when cleaning up your working copy, or if you want to store them in a separate repository allowing shelves to be shared among your team members.
Press Ctrl+Alt+S to open the IDE settings and select.
Click Change Shelves Location and specify the new location in the dialog that opens.
If necessary, select Move shelves to the new location to move existing shelves to the new directory.
