6. module System.FilePath.Posix

   A library for FilePath manipulations, using Posix style paths on all platforms. Importing System.FilePath is usually better. Given the example FilePath: /directory/file.ext We can use the following functions to extract pieces.

   • takeFileName gives "file.ext"
   • takeDirectory gives "/directory"
   • takeExtension gives ".ext"
   • dropExtension gives "/directory/file"
   • takeBaseName gives "file"
   And we could have built an equivalent path with the following expressions:
   • "/directory" </> "file.ext".
   • "/directory/file" <.> "ext".
   • "/directory/file.txt" -<.> "ext".
   Each function in this module is documented with several examples, which are also used as tests. Here are a few examples of using the filepath functions together: Example 1: Find the possible locations of a Haskell module Test imported from module Main:

   [replaceFileName path_to_main "Test" <.> ext | ext <- ["hs","lhs"] ]
   

   Example 2: Download a file from url and save it to disk:

   do let file = makeValid url
   System.Directory.createDirectoryIfMissing True (takeDirectory file)
   

   Example 3: Compile a Haskell file, putting the .hi file under interface:

   takeDirectory file </> "interface" </> (takeFileName file -<.> "hi")

7. module System.OsPath.Posix

   No documentation available.

8. data PosixChar

   filepath	System.OsPath.Posix

   No documentation available.

9. type PosixPath = PosixString

   filepath	System.OsPath.Posix

   Filepaths are char[] data on unix as passed to syscalls.

10. data PosixString

    filepath	System.OsPath.Posix

    Commonly used Posix string as uninterpreted char[] array.
