IntelliJ IDEA makes it possible to set up line separators (line endings) for the newly created files, and change line separator style for the existing files.

In this section:

To set up line separators for the new files
  1. Open Project Settings dialog, expand Code Style, and click General.
  2. From the Line separator (for new files) drop-down list, select the desired line separator style:

    lineSeparatorForNewFiles

  3. Apply changes and close the dialog.
To view line ending style for the current file
  1. Open the desired file in the editor, as described in the section Opening and Reopening Files.
  2. View the Status bar: the current line endings style is denoted by the dedicated icon with the specified style, for example, uiStatusLineEnding.
To change line separator for a file, currently opened in the editor
  1. Open the desired file in the editor, as described in the section Opening and Reopening Files.
  2. Click the line separator spin box in the Status bar, and choose the desired line ending style from the pop-up menu:

To change line separator for a file or directory, selected in the project view

    Note that if a directory is selected, the line ending style applies to all nested files recursively.
