2. In the main menu, go to Code | Reformat Code or press Ctrl+Alt+L.

Reformat a file

2. In the Reformat File dialog that opens, if you need, select the following reformatting options:

   • Code cleanup: select this option to run the code cleanup inspections.

   • Do not keep line breaks: reformat line breaks according to the code style settings. This option overrides the Keep when reformatting | Line breaks setting.

   If you want to see the exact changes made to your code during the reformatting, use the Local History feature.

Reformat line indents

You can reformat line indents based on the specified settings.

   • From the All file types list, select the types of files in which you want to reformat code.

   • Select Whole file or Changed lines if your project is under version control.

     If you select Changed lines, reformatting will apply only to the lines of code that have been changed locally, but not yet checked in to the repository.

1. In the Settings dialog (Ctrl+Alt+S) , go to Editor | Code Style.

2. Switch to the Formatter tab and in the Do not format field, enter the files and directories that you want to exclude using a glob pattern.

   You can specify several glob patterns separated with a semicolon ;. If you click , the field will expand, and each pattern will be shown on a separate line.

3. Apply the changes and close the dialog.
