Configuring line separators
With WebStorm, you can set up line separators (line endings) for newly created files, and change line separator style for existing files.
Configure line separators for new files
Press Ctrl+Alt+S to open the IDE settings and select.
To configure line separators for new projects, go to .
From the Line separator list, select the line separator style you want to apply.
Apply the changes and close the dialog.
Change line separators for the current file
The line separator widget appears in the status bar of the IDE window when a file is open in the editor.
Click the widget and select another line separator style.
Alternatively, select another ending style in.
Changing the line separator style is reflected in the Local history of a file.
Change line separators for a file or directory
Select a file or a directory in the Project tool window Alt+1.
If you select a directory, the new line ending style will be applied to all nested files recursively.
From the main menu, select, and then select a line ending style from the list.
