20.1 Whitespace

  • Tabs and Spaces - Lines are indented using tabs or spaces depending on how the following preferences from File > Preferences > Settings > Text Editor > Editor are configured:

    • The Insert Spaces (editor.insertSpaces) option controls if the indentation will use space characters or tabs.

    • The Tab Size (editor.tabSize) option controls the size of a tab in spaces.

Note: When the editor.detectIndentation preference is enabled, Visual Studio Code will automatically detect the indentation style of any file opened in the editor. The detected values will be displayed in the right corner of the Status Bar and will have a higher priority over the editor.insertSpaces and editor.tabSize settings when the formatter is invoked.
