Block comments in html.erb templates in rails

Question

How do you comment out html mixed with ruby code?

some text <% ... %> more text <%= ... %>
something else
<% ... %>

In js

Answer 1

Use a HEREDOC called comment

Pros:

• Self-explanatory that this is a comment
• Works for erb and HTML tags
• Has ok syntax highlighting (as one long string)

Cons:

• Weird 3 line closing syntax
• No keyboard shortcuts

Code:

The opening tag can be

<% <<-COMMENT %>

the above closing erb tag is just for looks (to match the end),
but don't put anything else there, it may show up on the page

or

<%
<<-COMMENT
%>

Anything here won't run or show up in the browser

    this will not be displayed in the browser
     even in the developer's tools 


<% 1_000_000_000_000.times do |count| %>

for the <%= count %>'th time, this won't run a trillion times,
this is all just a string

all of these %>, <%, <% end %>, end, do,
