Trailing Whitespace Visualizer

This extension will highlight and remove any trailing whitespace on any line in any editor in Visual Studio. This makes it really easy to get rid of those annoying invisible characters.

You can change the background color easily from the Tools -> Options -> Fonts and Colors menu. The item is called "Trailing Whitespace".

Remove trailing whitespace

You can very easily delete all the trailing whitespace in a file by executing the Delete Horizontal White Space command found in Edit -> Advanced or by using the shortcut key combination Ctrl+K, Ctrl+\

Changing the background color

You can change the background color from the Tools -> Options dialog under the Environment -> Fonts and Colors settings.

The setting is for the Text Editor and the display item is called Trailing Whitespace.

Ignore rules

It's easy to add specify what file patterns to ignore. Any ignored file will have whitespace colorized or removed on save.

By default, file paths with any of the following strings contained in it will be ignored:

• \node_modules\
• \bower_components\
• \typings\
• \lib\
• .min.
• .md
• .markdown

You can modify these rules in the Tools -> Options dialog.

Remove on save

Every time a file is saved, all trailing whitespace is removed. This can be disabled in the Tools -> Options dialog.
