Question

Is there a way to set the tab size in IntelliJ for a single file only, or at most for a single project?

I use a tab size of 3 for all my code; however, I’m collaborating on a project with an author who prefers a tab size of 4. Is there a way to set the tab size to 4 for only those files that are part of this project?

Answer 1

Open the Settings dialog by navigating to File->Settings. Under Project Settings [yourproject] on the left side of the dialog, navigate to Code Style->General. The Tab size is configurable on that pane, and the value you provide applies only to the project named yourproject.
