Convenience decorators for reading and writing to compressed archives

Project Description

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

Installation

easy_install -U archiveIO

Usage

import archiveIO
import os
from six import BytesIO

# Define a function that generates archive contents
@archiveIO.save
def save(targetPath):
    open(targetPath, 'wt').write('xxx')
# Define a function that processes archive contents
@archiveIO.load
def load(sourcePath):
    return open(sourcePath, 'rt').read()

# Save archives
save('sample.txt')
save('sample.txt.zip')
save('sample.txt.tar.gz')
save('sample.txt.tar.bz2')
save('sample.txt.tar')
# Load archives
assert 'xxx' == load('sample.txt')
assert 'xxx' == load('sample.txt.zip')
assert 'xxx' == load('sample.txt.tar.gz')
assert 'xxx' == load('sample.txt.tar.bz2')
assert 'xxx' == load('sample.txt.tar')

# Create an archive containing two files
@archiveIO.save
def save(targetPath):
    open(targetPath + '.txt', 'wt')
    open(targetPath + '.csv', 'wt')
targetPath = 'sample.zip'
save(targetPath)
# Target CSV files before TXT files
@archiveIO.load(extensions=['.csv', '.txt'])
def load(sourcePath):
    return os.path.basename(sourcePath)
assert 'sample.csv' == load(targetPath)

# Use MyException instead of IOError
class MyException(Exception):
    pass
@archiveIO.load(CustomException=MyException)
def load(sourcePath):
    return sourcePath
try:
    load('xxx.tar.gz')
except MyException, error:
    print error

# Compress directly into a string buffer
archive = archiveIO.Archive(BytesIO(), '.tar.gz')
archive.save([
    'sample.txt',
    'sample.txt.zip',
])
# Uncompress into a temporary folder
with archiveIO.TemporaryFolder() as temporaryFolder:
    for filePath in archive.load(temporaryFolder):
        print filePath
