Local History helps you constantly track all changes made to project files and its structure, independently of version control. Unlike version control systems that show differences between specific commits, Local History automatically maintains revisions for all meaningful changes, both from the IDE and external changes. This produces a detailed timeline of changes in project structure and source code with the ability to roll back to any point if necessary.

View Local History for a file
Find the file that you want to study and open it in the editor.

This will bring up a dialog with the list of changes to the file in the left and a diff viewer for the selected change on the right.

In some cases, you may not want to view Local History for the whole file, but only for specific source code elements: classes, their members (fields and methods), or the selected fragment of text.
View Local History for a class, field, or method
Right-click the name of a class, field, or method in the editor and selectfrom the context menu.
View Local History for a source code fragment
Select a code fragment that you want to study.
Right-click the selection and choosefrom the context menu.
There is another global entry point for the local history that allows you to quicklly list local changes from the entire project.

Select a revision in the left part of the Local History dialog.
Do one of the following:
To revert the whole file or directory to the state of this revision, right-click it and choose Revert from the context menu or click on the toolbar.
To revert specific changes in a file, switch the diff view to the Side-by-side-viewer using the selector on the toolbar, and then click next to the desired changes.
This adds a new revision to the Local History.
Add labels to specific states Local History
Local History revisions are normally marked with timestamps, which are not easy to navigate. Some revisions are automatically marked with labels based on predefined events: running tests, deploying apps, committing changes, etc. You can always add a new label to mark the current state of the Local History, for example right before you start a massive refactoring.
Selectfrom the main menu.
In the dialog that opens, type any meaningful name for the label and click OK.
Share Local History
Local History does not support shared access, it is stored locally and intended only for personal use. However, you can create a patch file with changes relative to a specific revision, which you can share with others.
Select a revision in Local History dialog and click Create Patch on the toolbar.
In the dialog that opens, specify how you want to create the new patch.
Retention period for Local History

Location of Local History files
Local History is stored as binary files under the LocalHistory subdirectory in the GoLand system directory.
You can change the location of the system directory using the idea.system.path property.
