Template comments?

Rails
1

Is there a way to put comments in templates (not using
HTML)? It appears Ruby only supports single-line
comments (#), and not multiline (/* … */). Right now
I use:

<% if 0==1 %>
comments …
<% end %>

I think I tried ‘if 0’ but it caused an error.

Thanks,
csn

odd, as that’s from a template I’ve used recently, and it works fine.

They do have to be on seperate lines because the ‘=’ has to be the 1st
character on the line. This will not work:

<% =begin

commented code here.

=end %>

Actually, what happens is the enclosed code still gets
executed. ?

<%
=begin

commented code here.

=end
%>

I tried that, but got errors - Ruby appears to try to
interpret the comments as code. Same goes when using
if/end (unless the comments are outside of <% …
%>).

Ah, that’s what it was - I had the block indented.

Sweet. Only problem is if there are additional code
tags in the block, e.g.

<%#
comment
comment
<%= @foo %> ← @foo gets outputted
comment
<% if 1 %> ← this block causes a syntax error
bar
<% end %>
comment
%>

Ah well, guess just use ‘if false/end’ around blocks
like that.
