Hi Simon
I've just come across this again. It's quite inconvenient that
takeDirectory "foo" == ""
because it means that you can't say
doesDirectoryExist (takeDirectory f)
Yes, I came across this the other day. And am leaning towards agreeing with you.
I think its reasonable if splitFileName keeps the same behaviour, and dropFileName as well, but takeDirectory follows the new behaviour. So:
takeDirectory "foo" = "." takeDirectory "foo/bar" = "foo"
dropFileName "foo" = "" dropFilename "foo/bar" = "foo/"
Does that sound like a plan that suits everyone?
That seems strange, actually. I would expect, perhaps naively, that takeDirectory == fst . splitFileName dropFileName == takeDirectory is there a good reason for these not to be true? Cheers, Simon
