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.
