Learned something interesting (to me) today.

In a fixture file I'm using to test some db code, I need a field to  
contain an empty string. I had no idea how to encode that in YAML. I  
checked the faq but it consists of one entry about tabs. :-)

I also searched this list and the Rails list going back to Jan 2005  
and came up dry.

irb to the rescue:

cremes$ irb
irb(main):001:0> require 'yaml'
=> true
irb(main):002:0> empty = ""
=> ""
irb(main):003:0> empty.to_yaml
=> "--- \"\"\n"

I put that into my fixture file (just the \"\") and everything is  
peachy. Next time I'll experiment with irb *first*.
