Hi Neil,
I'm having some problems using filepath in GHC. I think some of these we might have discussed before, but if so I've forgotten what the conclusion was, if any, and I can't see the answers in the docs.
The first is this: Prelude System.FilePath> "." "foo" "./foo" which means we get things like [2 of 2] Compiling GHC.Foo ( ./GHC/Foo.hs, ./GHC/Foo.o ) rather than [2 of 2] Compiling GHC.Foo ( GHC/Foo.hs, GHC/Foo.o ) Is there a reason the result shouldn't be "foo"?
The function that does that is normalise. It strips leading . and colapses things like foo/../
Possibly relatedly, the current directory seems to be "" rather than ".". This turns up in at least a couple of areas: Prelude System.FilePath> normalise "." ""
That's just a bug. I've reported that before. I though it was fixed but seems not. We had that problem in Cabal where people specified . as one of the search dirs. Duncan
