Linter Rule: Disallow empty ERB tags
Rule: erb-no-empty-tags
Description
Disallow ERB tags (<% %> or <%= %>) that contain no meaningful content i.e., tags that are completely empty or contain only whitespace.
Rationale
Empty ERB tags serve no purpose and may confuse readers or indicate incomplete code. They clutter the template and may have been left behind accidentally after editing.
Examples
✅ Good
html
<%= user.name %>
<% if user.admin? %>
