Installation
Install directly from PyPI, using pip
pip install fs.archive
Usage
The fs.archive.open_archive context manager is the easiest way to open an archive filesystem, with an archive located on any other filesystem, determining from the file extension the type to use :
>>> from fs import open_fs
>>> from fs.archive import open_archive
>>> my_fs = open_fs(u'temp://')
>>> with open_archive(my_fs, u'test.zip') as archive:
... type(archive)
<class 'fs.archive.zipfs.ZipFS'>
All the filesystems implemented in fs.archive also support reading and writing from and to a file handle a file handle:
>>> import fs.archive.tarfs
>>> with fs.open_fs(u'mem://') as mem:
... with fs.archive.tarfs.TarFS(mem.openbin(u'test.tar', 'w')) as tar:
... tar.setbytes(u'hello', b'Hello, World!')
... with fs.archive.tarfs.TarFS(mem.openbin(u'test.tar', 'r+')) as tar:
... tar.isfile(u'hello')
True
fs.archive declares three abstract base classes in fs.archive.base:
ArchiveSaver: defines how an archive is saved (in essence, a class managing the compression of a filesystem)
ArchiveReadFS: a read-only filesystem that implements the methods required to read the archive
ArchiveFS: a proxy filesystem used to make an archive seemingly writable
