How does it differ to getCurrentDirectory/setCurrentDirectory in System.Directory? On 4 December 2013 14:38, Benjamin Franksen < benjamin.franksen@helmholtz-berlin.de> wrote:

Module System.Posix.Directory of the unix package defines

getWorkingDirectory :: IO FilePath changeWorkingDirectory :: FilePath -> IO ()

I believe the functionality is quite portable and not limited to unix-like systems. I know that e.g. Windows has chdir and getcwd. Module Filesystem of the system-fileio package has

getWorkingDirectory :: IO FilePath setWorkingDirectory :: FilePath -> IO ()

I propose to add these functions to System.Environmant or maybe System.Directory.

Rationale:

(1) This is standard functionality that should at least be in the Haskell Platform, if not in the standard libraries.

(2) I would like to avoid depending on an extra package just to have these two very basic functions available in a OS independent way.

(3) "system-fileio".Filesystem does not seem to be the right place for this.

The last point may be arguable, but the first two are plain common sense IMO.

The functionality is similar but different, insofar as Windows still has legacy drive paths and the current directory is maintained separately for each one; I would expect this to be exposed in a Windows version. That said, there are already setCurrentDirectory and getCurrentDirectory in System.Directory for portable versions. -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
