Producing single-line comments with HAML?

I'm trying to generate a comment on a single line at the end of an HTML file:

<!-- generated by SERVER1 --> 

I have tried

/ generated by #{@server_name} 

But this outputs it over 3 lines -

<!-- generated by SERVER1 --> 

I've tried

/ generated by #{@server_name} 

But that doesn't evaluate the @server_name var -

<!-- generated by #{@server_name} --> 

Any ideas?

Just as you can drop back to raw HTML output when you want, so you can drop in raw HTML comments, even with interpolation.

This template:

- @foo = 42 #test1 / Hello #{@foo} #test2 <!-- Hello #{@foo} --> 

Produces this output:

<div id='test1'> <!-- Hello 42 --> </div> <div id='test2'> <!-- Hello 42 --> </div> 

Tested with Haml v3.1.4 (Separated Sally)

It's still an open issue: . I think you're stuck with the multiline comment for now, even though nex3 says single line interpolation should work.
