Save and revert changes
MPS automatically saves changes that you make in your files. Saving is triggered by various events, such as compiling, running, debugging, performing version control operations, closing a file or a project, or quitting the IDE. Saving files can be also triggered by third-party plugins.
Most of the events that trigger auto-save are predefined and cannot be configured, but you can be sure that changes will not be lost .
Configure autosave behavior
In the Settings dialog (Ctrl+Alt+S) , select .
Under Autosave, configure the following options:
Save files when switching to a different application or a built-in terminal: Save all modified files when you switch from MPS to a different application.
Save files if the IDE is idle for N seconds: Save all modified files at regular time intervals.
Apply the changes and close the dialog.
Mark files with unsaved changes
You can mark unsaved files with an asterisk (*) on the file tab:
In the Settings dialog (Ctrl+Alt+S) , select .
Select the Mark modified (*) checkbox.
Apply the changes and close the dialog.
After that, the tab of the file in which you have unsaved changes will be marked with an asterisk.
If you use version control integration, names of all modified files will be also marked with a dedicated color on the file tab and in the Project tool window.
Save changes manually
You can always save your changes manually:
Press Ctrl+S or select from the main menu.
Revert changes
For most recent changes, including refactorings, press Ctrl+Z or choose from the menu.
For the most robust tracking of all changes, use a version control system.
