Codec.Archive

This module contains higher-level functions for working with archives in Haskell. See Codec.Archive.Foreign for direct bindings to libarchive.

High-level functionality

unpackToDir

Arguments

:: FilePath

Directory to unpack in

-> ByteString

ByteString containing archive

-> IO ()

unpackArchive

Arguments

:: FilePath

Filepath pointing to archive

-> FilePath

Dirctory to unpack in

-> IO ()

This is more efficient than

unpackToDir "llvm" =<< BS.readFile "llvm.tar"

entriesToFile :: Foldable t => FilePath -> t Entry -> IO ()

Write some entries to a file, creating a tar archive. This is more efficient than

BS.writeFile "file.tar" (entriesToBS entries)

entriesToFileZip :: Foldable t => FilePath -> t Entry -> IO ()

Write some entries to a file, creating a zip archive.

entriesToFile7Zip :: Foldable t => FilePath -> t Entry -> IO ()

Write some entries to a file, creating a .7z archive.

entriesToBS :: Foldable t => t Entry -> ByteString

Returns a ByteString containing a tar archive with the Entrys

entriesToBS7zip :: Foldable t => t Entry -> ByteString

Returns a ByteString containing a .7z archive with the Entrys

entriesToBSzip :: Foldable t => t Entry -> ByteString

Returns a ByteString containing a zip archive with the Entrys

readArchiveFile :: FilePath -> IO [Entry]

Read an archive from a file. The format of the archive is automatically detected.

readArchiveBS :: ByteString -> [Entry]

Read an archive contained in a ByteString. The format of the archive is automatically detected.
