Convenience decorators for reading and writing to compressed archives

Here are some decorators for reading and writing to compressed archives.

Installation

easy_install -U archiveIO

Usage

import archiveIO

@archiveIO.save
def save(targetPath, content):
    'Example save function'
    open(targetPath, 'wt').write(content)
    # archiveIO.save() will compress everything in the folder containing targetPath
    backupPath = os.path.join(os.path.dirname(targetPath), 'backup.txt')
    open(backupPath, 'wt').write(content)

@archiveIO.load
def load(sourcePath):
    'Example load function'
    content = open(sourcePath, 'rt').read()
    # archiveIO.load() will extract the archive to a folder and run the function on each file in the folder
    if os.path.basename(sourcePath) == 'backup.txt': raise IOError
    backupPath = os.path.join(os.path.dirname(sourcePath), 'backup.txt')
    assert open(backupPath, 'rt').read() == content
    return content

data = 'xxx'
save('sample.txt', data)
save('sample.txt.zip', data)
save('sample.txt.tar.gz', data)
save('sample.txt.tar.bz2', data)
save('sample.tar', data)
assert load('sample.txt') == data
assert load('sample.txt.zip') == data
assert load('sample.txt.tar.gz') == data
assert load('sample.txt.tar.bz2') == data
assert load('sample.txt.tar') == data
