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.

prependCurrentDirectoryWith :: IO FilePath -> FilePath -> IO FilePath Source #
Convert a path into an absolute path. If the given path is relative, the current directory is prepended. 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 fail with the same exceptions as getCurrentDirectory.
(internal API)
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 map to the same directory.

Constructors
| XdgData | For data files (e.g. images).

| XdgConfig | For configuration files.
Defaults to |
| XdgCache | For non-essential files (e.g. cache).

data XdgDirectoryList Source #
Search paths for various application data, as specified by the XDG Base Directory Specification.
