That doesn't work. It only gives you the leaf (basename), not the path.

    Thanks - good to know that's been fixed now. I don't know why all the previous requests were marked as "wontfix".

      Huh? Are you sure they weren't marked as duplicates of the original request made in 2010, which was closed as "fixed" in 2012? The functionality was available as a library on hackage starting in 2009. It was added to the standard library in 2012 as part of ghc 7.6.1. Your website says you were testing with 7.6.3. https://www.haskell.org/ghc/docs/latest/html/users_guide/release-7-6-1.html https://www.haskell.org/ghc/docs/latest/html/users_guide/rel...

        I don't remember exactly how I searched for it, but the top hit on Google for "haskell argv[0]" today is https://ghc.haskell.org/trac/ghc/ticket/3199 https://ghc.haskell.org/trac/ghc/ticket/3199, which is marked "wontfix" and includes a workaround (which I used). The second link is to Environment.hs, which would have solved my problem, if I'd known what I was looking for. I think I'd have just clicked Back when I saw it was library source code, though. The third link is http://hackage.haskell.org/package/system-argv0-0.1 http://hackage.haskell.org/package/system-argv0-0.1 - which says "Use this instead of System.Environment.getProgName if you want the full path, and not just the last component." (note: technically, my code was still the correct solution, since 0install targets Ubuntu 12.04, but yes ideally I would have found that newer versions did support it more simply)
