High-level functionality

unpackToDir Source #

Arguments

:: FilePath	Directory to unpack in
-> ByteString	`ByteString` containing archive
-> ArchiveM ()

unpackToDirLazy Source #

Arguments

:: FilePath	Directory to unpack in
-> ByteString	`ByteString` containing archive
-> ArchiveM ()

In general, this will be more efficient than unpackToDir

Since: 1.0.4.0

unpackArchive Source #

Arguments

:: FilePath	Filepath pointing to archive
-> FilePath	Dirctory to unpack in
-> ArchiveM ()

This is more efficient than

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

entriesToFile :: Foldable t => FilePath -> t Entry -> ArchiveM () Source #

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

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

Since: 1.0.0.0

entriesToFileZip :: Foldable t => FilePath -> t Entry -> ArchiveM () Source #

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

Since: 1.0.0.0

entriesToFile7Zip :: Foldable t => FilePath -> t Entry -> ArchiveM () Source #

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

Since: 1.0.0.0

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

Returns a ByteString containing a tar archive with the Entrys

Since: 1.0.0.0

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

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

Since: 1.0.0.0

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

Returns a ByteString containing a zip archive with the Entrys

Since: 1.0.0.0

entriesToBSL :: Foldable t => t Entry -> ByteString Source #

In general, this will be more efficient than entriesToBS

Since: 1.0.5.0

entriesToBSLzip :: Foldable t => t Entry -> ByteString Source #

Since: 1.0.5.0

entriesToBSL7zip :: Foldable t => t Entry -> ByteString Source #

Since: 1.0.5.0

readArchiveFile :: FilePath -> ArchiveM [Entry] Source #

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

Since: 1.0.0.0

readArchiveBS :: ByteString -> Either ArchiveResult [Entry] Source #

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

Since: 1.0.0.0

readArchiveBSL :: ByteString -> Either ArchiveResult [Entry] Source #

Read an archive lazily. The format of the archive is automatically detected.

In general, this will be more efficient than readArchiveBS

Since: 1.0.4.0

packFiles Source #

Arguments

:: Traversable t
=> t FilePath	Filepaths relative to the current directory
-> IO ByteString

Pack files into a tar archive

Since: 2.0.0.0

packFilesZip :: Traversable t => t FilePath -> IO ByteString Source #

Since: 2.0.0.0

packFiles7zip :: Traversable t => t FilePath -> IO ByteString Source #

Since: 2.0.0.0

packToFile Source #

Arguments

:: Traversable t
=> FilePath	`.tar` archive to be created
-> t FilePath	Files to include
-> ArchiveM ()

Since: 2.0.0.0

packToFileZip :: Traversable t => FilePath -> t FilePath -> ArchiveM () Source #

Since: 2.0.0.0

packToFile7Zip :: Traversable t => FilePath -> t FilePath -> ArchiveM () Source #

Since: 2.0.0.0
