listDirectory :: FilePath -> IO [FilePath] Source #
returns a list of all entries in dir without
the special entries (listDirectory
dir.
and ..
).
The operation may fail with:
HardwareFault
A physical I/O error has occurred.[EIO]
InvalidArgument
The operand is not a valid directory name.[ENAMETOOLONG, ELOOP]
isDoesNotExistError
The directory does not exist.[ENOENT, ENOTDIR]
isPermissionError
The process has insufficient privileges to perform the operation.[EACCES]
isFullError
Insufficient resources are available to perform the operation.[EMFILE, ENFILE]
InappropriateType
The path refers to an existing non-directory object.[ENOTDIR]
Since: directory-1.2.5.0
makeAbsolute :: FilePath -> IO FilePath Source #
Convert a path into an absolute path. If the given path is relative, the
current directory is prepended and then the combined result is normalized.
If the path is already absolute, the path is simply normalized. The
function preserves the presence or absence of the trailing path separator
unless the path refers to the root directory /
.
If the path is already absolute, the operation never fails. Otherwise, the
operation may fail with the same exceptions as getCurrentDirectory
.
Since: directory-1.2.2.0
