Comment Rulers

Comment Rulers is a Visual Studio Code extension that helps you keep your code's comments within a specified range by visualizing where the comment lines should start and end.

The extension adds green lines at the first and 80th character positions, allowing you to easily identify and adjust comments that aren't in the desired range.

With Comment Rulers, you can ensure that your comments are concise and easy to read, improving the readability and maintainability of your codebase.

Known Issues

Rulers can be misplaced:
Comments in string templates aren't supported:
```
let num = 12;
let str = `${num /* comment */}`;
```
Expected:
Delimiters can't be configured to be just indented: This heredoc is terminated early, since it's not possible to configure that DOC can only be indented <<-DOC (vscode is wrong here):
```
<<-DOC
A heredoc ended with DOC
DOC
```
Expected:
Incorrect tab indentation isn't handled properly:
