Hello,
I'm new to Ruby (coming from Python) and I already have trouble.
The following code (on Windows XP, Ruby 1.8.5):
Dir.chdir 'c:/documents and settings/antoine/desktop'
Dir.mkdir 'test'
Dir.chdir 'test'
%w{ a b c }.each { |f| File.open(f+'.txt', 'w').close }
Dir.foreach('.') { |f| File.delete f }
throws this error message:
problem.rb:5:in `delete': Permission denied - . (Errno::EACCES)
from problem.rb:5
from problem.rb:5:in `foreach'
from problem.rb:5
I've tried to find an answer to this strange behaviour for a couple of hours now, but I can't find one. Could anybody point me to a solution of the problem?
Kind regards,
antoine

I can see a problem in your code, but I'm not sure whether or not it's related
to the error you get (I don't have use windows, so I can't test). Dir.foreach
passes to the block also '.' and '..', which represent respectively the
current directory and its parent. File.delete can't deal with directories
(and at any rate, I don't think you want to delete the current directory), so
it raises an exception. On linux, trying to use File.delete on a directory
raises a Errno::EISDIR exception, but since exceptions in the Errno module ar
operating system-dependent, it may be that in windows it raises a
Errno::EACCES exception.
I hope this helps

Dir.foreach also returns '.' and '..'.
The error message is saying you can't delete the current directory (it still contains files).
I had the same problem with the logfiles on my script-framework. They
just could not be deleted on windows, until I tried to close them
explicitly after any usage. I don't know windows file-locking
mechanism, but closing any open file(handles) will save you troubles
anyway.
In your code above, you are doing a close, but right after opening,
maybe that's a problem?

Thanks everybody,
'.' and '..' effectively where the source of the problem.
