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 * * * Yahoo!

They do have to be on seperate lines because the ‘=’ has to be the 1st character on the line.

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. csn — Ezra Z.
