Simon,
Thanks for this. I think the (obvious when you think about it) thing
I’ve learned today is that ruby uses inspect when generating error
messages: I headed off down this blind alley when I got an error
something like:
t.rb:1:in open': No such file or directory - "J:\\dir\\subdir\\" (Errno::ENOENT) from t.rb:1:in entries’
from t.rb:1
… and I assumed that “J:\dir\subdir\” was what ruby was ‘seeing’.
I must look elsewhere for the true cause of my bug.
All the best,
Jon

You’re being bitten by the fact that p uses inspect, and
String.inspect gives you a “displayable” representation of a string
that can be re-evalled back into ruby.
“\” does what you want:
% ruby -e ‘print “\”’
