Hi all,
Is there tags for block comment in rhtml, so that I can comment out a
block of code (mainly for testing/debuging)?
html comment can't prevent ERb code from processed
\<%# text inside become comment %\> only comment out the the tag
It’s quite inconvenient not to have such facility.
Thanks,
- Chuong

You mean like:
\<% if false -%\>
…everything skipped…
\<% end -%\>
?

Hi Michael,
It’s something like that, but your suggestion is just a workaround.
There’s no built-in in rhtml to do this? I want the editor to mark it
as comment also.
In Java JSP files, you have \<%-- comment --%\>
However your way is useful at some level.
Thanks,

Nope, doesn’t work.

I believe
=begin %\>
\<% your ruby code here %\>
\<% and some more %\>
=end %\>
will work. Make sure the ‘=’ sign is the first thing on a line.
