Bug #7608: Documentation, Std-lib, ERB
https://bugs.ruby-lang.org/issues/7608

Author: wonderingtomato (Tom Pave)

I believe the documentation for the ((<ERB::new|URL:http://ruby-doc.org/stdlib-1.9.3/libdoc/erb/rdoc/ERB.html#method-c-new>)) method could be improved. Specifically, the list of available arguments for the (({trim_mode})) paramenter doesn't seem complete. I found you can use the option (({"-"})) to make the tags (({<%   -%>})) work. (by the way... It looks like those tags aren't documented either).

Without that option the (({<%   -%>})) tags don't work properly. I made several tests and can confirm the issue affects both Ruby 1.8.7 and 1.9.3.
I've attached a short file (70 lines including whitespace) to reproduce the problem. Comments indicate what goes wrong, and I have provided a commented out line that works instead (as it uses the undocumented (({trim_mode="-"})) option).

I came across the issue while working on a plain ruby script, but I used the same code in a Rails app with no problems at all, so I guess that ERB text is parsed in Rails with (({trim_mode="-"})) by default.
