System.Directory.Internal
Description
Internal modules are always subject to change from version to version. The contents of this module are also platform-dependent, hence what is shown in the Hackage documentation may differ from what is actually available on your system.

Truncate the destination file and then copy the contents of the source file to the destination file. If the destination file already exists, its attributes shall remain unchanged. Otherwise, its attributes are reset to the defaults.
Copy all data from a file to a handle.
Copy data from one handle to another until end of file.
data XdgDirectory Source #
Special directories for storing user-specific application data, configuration, and cache files, as specified by the XDG Base Directory Specification.
Note: On Windows, XdgData and XdgConfig usually map to the same
directory.
Since: directory-1.2.3.0

data XdgDirectoryList Source #
Search paths for various application data, as specified by the XDG Base Directory Specification.
The list of paths is split using searchPathSeparator,
which on Windows is a semicolon.
Note: On Windows, XdgDataDirs and XdgConfigDirs usually yield the same
result.

createDirectoryInternal :: FilePath -> IO () Source #
c_PATH_MAX :: Maybe Int Source #
canonicalizePathWith :: ((FilePath -> IO FilePath) -> FilePath -> IO FilePath) -> FilePath -> IO FilePath Source #
findExecutablesLazyInternal :: ([FilePath] -> String -> ListT IO FilePath) -> String -> ListT IO FilePath Source #
prependCurrentDirectory :: FilePath -> IO FilePath Source #
Convert a path into an absolute path. If the given path is relative, the current directory is prepended and the path may or may not be simplified. If the path is already absolute, the path is returned unchanged. The function preserves the presence or absence of the trailing path separator.
If the path is already absolute, the operation never fails. Otherwise, the operation may throw exceptions.
Empty paths are treated as the current directory.
setCurrentDirectoryInternal :: FilePath -> IO () Source #
type Metadata = FileStatus Source #
modeFromMetadata :: Metadata -> Mode Source #
hasWriteMode :: Mode -> Bool Source #
setAccessPermissions :: FilePath -> Permissions -> IO () Source #
copyOwnerFromStatus :: FileStatus -> FilePath -> IO () Source #

copyFileWithMetadataInternal :: (Metadata -> FilePath -> IO ()) -> (Metadata -> FilePath -> IO ()) -> FilePath -> FilePath -> IO () Source #
getHomeDirectoryInternal :: IO FilePath Source #
$HOME is preferred, because the user has control over it. However, POSIX
doesn't define it as a mandatory variable, so fall back to getpwuid_r.
getXdgDirectoryFallback :: IO FilePath -> XdgDirectory -> IO FilePath Source #
