This is a small wrapper around the directory, unix, and Win32 packages, for use with system-filepath. It provides a consistent API to the various versions of these packages distributed with different versions of GHC.

In particular, this library supports working with POSIX files that have paths which can’t be decoded in the current locale encoding.


Changelog for system-fileio

  • Fix for Win32 2.6 and above #21
