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.

fileTypeIsDirectory :: FileType -> Bool Source #

Check whether the given FileType is considered a directory by the operating system. This affects the choice of certain functions e.g. removeDirectory vs removeFile.

fileTypeIsLink :: FileType -> Bool Source #

Return whether the given FileType is a link.

data Permissions Source #

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)

copyFileContents Source #

Arguments

:: FilePath	Source filename
-> FilePath	Destination filename
-> IO ()

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.

copyFileToHandle Source #

Arguments

:: FilePath	Source file
-> Handle	Destination handle
-> IO ()

Copy all data from a file to a handle.

copyHandleData Source #

Arguments

:: Handle	Source handle
-> Handle	Destination handle
-> IO ()

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.

Since: directory-1.2.3.0

Constructors

XdgData	For data files (e.g. images). Defaults to `~/.local/share` and can be overridden by the `XDG_DATA_HOME` environment variable. On Windows, it is `%APPDATA%` (e.g. `C:/Users/<user>/AppData/Roaming`). Can be considered as the user-specific equivalent of `/usr/share`.
XdgConfig	For configuration files. Defaults to `~/.config` and can be overridden by the `XDG_CONFIG_HOME` environment variable. On Windows, it is `%APPDATA%` (e.g. `C:/Users/<user>/AppData/Roaming`). Can be considered as the user-specific equivalent of `/etc`.
XdgCache	For non-essential files (e.g. cache). Defaults to `~/.cache` and can be overridden by the `XDG_CACHE_HOME` environment variable. On Windows, it is `%LOCALAPPDATA%` (e.g. `C:/Users/<user>/AppData/Local`). Can be considered as the user-specific equivalent of `/var/cache`.

data XdgDirectoryList Source #

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

Note: On Windows, XdgDataDirs and XdgConfigDirs yield the same result.

Since: directory-1.3.2.0

Constructors

XdgDataDirs	For data files (e.g. images). Defaults to `usrlocalshare` and `usrshare/` and can be overridden by the `XDG_DATA_DIRS` environment variable. On Windows, it is `%PROGRAMDATA%` or `%ALLUSERSPROFILE%` (e.g. `C:/ProgramData`).
XdgConfigDirs	For configuration files. Defaults to `etcxdg` and can be overridden by the `XDG_CONFIG_DIRS` environment variable. On Windows, it is `%PROGRAMDATA%` or `%ALLUSERSPROFILE%` (e.g. `C:/ProgramData`).
