zipfile-dclimplode

Monkey patch the standard zipfile module to enable DCL Implode support.

DCL stands for PKWARE(R) Data Compression Library.

Based on zipfile-deflate64 and zipfile-zstandard, which provides similar functionality but for the deflate64 algorithm. Unlike zipfile-deflate64, this package supports both compression and decompression.

Requires dclimplode for dclimplode bindings.

Note: if you need Python2, use zipfile39 instead (it is also compatible with Python3).

Installation

pip install zipfile-dclimplode

Usage

Anywhere in a Python codebase:

import zipfile_dclimplode  # This has the side effect of patching the zipfile module to support DCL Implode

Alternatively, zipfile_dclimplode re-exports the zipfile API, as a convenience:

import zipfile_dclimplode as zipfile

zipfile.ZipFile(...)

Compression example:

import zipfile_dclimplode as zipfile

zf = zipfile.ZipFile('/tmp/test.zip', 'w', zipfile.ZIP_DCLIMPLODED, compresslevel=3)
zf.write('large_file.img')

compresslevel: 1,2,3 (binary) 11,12,13 (ascii)
