Trailing Whitespace Fixer

This extension helps to identify and remove trailing whitespace. It includes the following features:

Trim on Enter

• If you hit Enter on a line that has trailing whitespace, it will be automatically removed.

• If you hit Enter before whitespace on a line, the whitespace will be removed.

  Example: The | character represents the cursor position.

   $arr = [
   	1, 2,| 3, 4
   ];

  Hitting Enter without Extension

   $arr = [
   	1, 2,
   	| 3, 4
   ];

  Hitting Enter with Extension

   $arr = [
   	1, 2,
   	|3, 4
   ];

Show Trailing Whitespace

• Any trailing whitespace on lines other than the current line will be highlighted in red.

Configuration

• If you want to allow lines that are only whitespace, you can enable the trailing-whitespace-fixer.allowWhitespaceOnlyLines setting. This is useful if you want to retain the current indentation level.
