Re: [Haskell-cafe] how to expand ~ in a filepath

There is no “should” here. It might be what you want, but it's not a universal standard. In Bash, “~foo” is not expanded. Sent from my iPad

But it's not just ~/ that should be expanded. All four of "~" "~/bar" "~foo" and "~foo/bar" should be expanded by a tilde-expander.

There's also https://github.com/xmonad/xmonad-contrib/blob/master/XMonad/Prelude.hs#L135-... although it also does a few other things.

Hello, unfortunately there is no "expandHomePath" or "realpath" helpers in the standard libraries. Searching for "FilePath -> IO FilePath" in hoogle shows an implementation in the hledger project: https://hackage-content.haskell.org/package/hledger-lib-1.43.2/docs/Hledger-...

… which check if the path begins with "~/", and replace that with the output of "getHomeDirectory"
