How to get this path in Haskell?

If I understand you correctly, you want

  takeDirectory `fmap` getProgName

I think getProgName does not give you the full path, but only the program name.

Neither does $0, does it? It depends on how the program is called. $0 depend everything you need to find your program (say, the relative or absolute path used), but getProgName does not. Here is an example:

./foo/foo

Here $0 will be "./foo/foo", but getProgName will be "foo". s/depend/contains
