Well, as you say, it's basically just a copy-paste with one small change:
36,38c36,38
< getFileCompl :: String -> IO [String]
< getFileCompl s = (filter notboring . lines) `fmap`
< runProcessWithInput "/bin/bash" [] ("compgen -A
file " ++ s ++ "\n")
---
> getDirCompl :: String -> IO [String]
> getDirCompl s = (filter notboring . lines) `fmap`
> runProcessWithInput "/bin/bash" [] ("compgen -A directory " ++ s ++ "\n")
As it stands, I would be adamantly against inclusion; such copy-paste
is not the Haskell way. Surely there is a better approach? I can't
help but suspect that this functionality may already be supplied by
another module (perhaps the Shell prompt meets your needs).
(On a side-note, I'm a little horrified by the 'notboring' function.
Is there really no library function for that? I quickly looked in
System.Filepath and System.Directory but turned up nothing named along
the lines of 'isHidden'.)
