[Haskell-cafe] filepath

[Johannes Waldmann]

Dear Cafe,

is there a library that provides an
"abstract representation of file and directory pathnames"?

This had been discussed before - e.g.,
https://mail.haskell.org/pipermail/libraries/2007-December/008769.html
(it's one message of a longer thread)

That message references an obsolete (?) Java library, they now have
https://docs.oracle.com/en/java/javase/13/docs/api/java.base/java/nio/file/Files.html

It seems that
https://hackage.haskell.org/package/filepattern-0.1.1/docs/System-FilePattern-Directory.html
does cover typical usage.

It is based on FilePath = String, and its implementation has some
"++"-ing. That indicates that an abstraction layer is missing - or, that
such a layer is indeed not required?

- J.W.
