Problem using Feedtools on my Rails project!

Hi

I'm trying to setup my app to use Feedtools amazing RSS
powers, but it 
fails miserably on the following line:

 logger.debug("Description:#{FeedTools::Feed.open(&qu
ot;http://rss.
slashdot.org/Slashdot/slashdot").items.first.descr
iption}")

The stack trace says:

wrong number of arguments (0 for 1)

/usr/local/lib/ruby/gems/1.8/gems/mongrel-0.3.13.3/lib/mongr
el/debug.rb:121:in

`index'
/usr/local/bin/mongrel_rails:18


I've put the 'require 'feed_tools' line in my
config/environment.rb

BUT the most amazing thing is that I can run script/console
and, lo and 
behold:

>> require 'feed_tools' 
=> false
>> FeedTools::Feed.open("http://rss.
slashdot.org/Slashdot/slashdot").items.first.descr
iption

It works flawlessly!  What gives?

CRAP!  Damn you Mike C., I *told* you adding that was a bad
idea.  No
cookie for you.

Ok, only Mike will get what I'm talking about, but
basically I goofed
*big* time.  Wait a few minutes because now I have to do a
0.3.13.4
release of Mongrel.

Basically, I threw in request logging at the request of Mike
Clark, who
then promptly didn't need it, but I left it in.  Problem is
the
mongrel/debug.rb file does a lot of nasty stuff and
shouldn't be
included unless explicitly requested and is temporary.  One
of the
things it does is track file opens/closes with Kernel.open
hacks, and
those seem to be messing with the Feedtools *wonderful*
hacks that allow
an open call with no arguments.

Give me an hour.

FeedTools has an open call with no arguments?  Really?  News
to me.

Maybe the two nested sets of double quotes? Try changing to
single 
quotes around the URL?

Nah, Zed's analysis is correct.  You'll note that:

"foo #{"bar"} baz"
=> "foo bar baz"

Thanks for the info! I guess many years of conditioning
prevented me 
from even trying it

(It still seems insidiously wrong, somehow....)

Any updates on this, Zed?   Sorry for nagging again, but I
haven't seen
any 0.3.13.4 release on the Rubyforge page.

Coming soon.  I've got a pre-release out but it has
problems with Ajax
requests so I'm working on it a bit more.  Probably by this
weekend.

Thank you, Zed.  Mongrel rocks!  You rock!

Since this issue keeps coming up, I applied a tiny patch to
the copy of 
HTree included with FeedTools that should prevent the
problem from 
happening.  It's checked into Subversion, but you're not
likely to see a 
release of 0.2.27 anytime soon, so I'm not sure how useful
that will be.
