System.Posix.Directory.Traversals

Description

Traversal and read operations on directories.

Synopsis

Documentation

getDirectoryContents :: RawFilePath -> IO [(DirType, RawFilePath)] Source

Gets all directory contents (not recursively).

getDirectoryContents' :: Fd -> IO [(DirType, RawFilePath)] Source

Like getDirectoryContents except for a file descriptor.

To avoid complicated error checks, the file descriptor is always closed, even if fdOpendir fails. Usually, this only happens on successful fdOpendir and after the directory stream is closed. Also see the manpage of fdopendir(3) for more details.

allDirectoryContents :: RawFilePath -> IO [RawFilePath] Source

Get all files from a directory and its subdirectories.

Upon entering a directory, allDirectoryContents will get all entries strictly. However the returned list is lazy in that directories will only be accessed on demand.

Follows symbolic links for the input dir.

allDirectoryContents' :: RawFilePath -> IO [RawFilePath] Source

Get all files from a directory and its subdirectories strictly.

Follows symbolic links for the input dir.

traverseDirectory :: (s -> RawFilePath -> IO s) -> s -> RawFilePath -> IO s Source

Recursively apply the action to the parent directory and all files/subdirectories.

This function allows for memory-efficient traversals.

Follows symbolic links for the input dir.

readDirEnt :: DirStream -> IO (DirType, RawFilePath) Source

packDirStream :: Ptr CDir -> DirStream Source

unpackDirStream :: DirStream -> Ptr CDir Source

fdOpendir :: Fd -> IO DirStream Source

Binding to fdopendir(3).

realpath :: RawFilePath -> IO RawFilePath Source

return the canonicalized absolute pathname

like canonicalizePath, but uses realpath(3)
