pyarchive

Pyarchive provide a bridge between file-like objects and libarchive, making it easy to use and extend libarchive itself. For instance, libarchive doesn't support bzip3 at this moment, however, pyarchive can do that with the help of other libraries.

import bz3
from pyarchive import ArchiveRead

with bz3.open("test.tar.bz3", 'rb') as f:
    a = ArchiveRead()
    a.support_filter_all()
    a.support_format_all()
    a.open(f, 1000)
    for entry in a.iter_entries():
        print(entry.pathname_w)
        a.skip()

Besides, it's also possible to read a file in memory using open_memory method, and read a fd using open_fd

Build

Build pyarchive with all features available is not very easy, especially on Windows, you'll have to link against the right libarchive. The recommend way is to use a conda environment. Use conda install -c conda-forge libarchive to install a pre-build libarchive with header-files available, and build use the following script

python -m pip install -r requirements.txt
python setup.py sdist bdist_wheel --use-cython --lib-path "D:\conda\envs\py310\Library\lib\archive.lib" --include-path "D:\conda\envs\py310\Library\include"

On linux, this may be

python -m pip install -r requirements.txt
python setup.py sdist bdist_wheel --use-cython --lib-path "/root/conda/envs/py310/Library/lib/libarchive.so" --include-path "/root/conda/envs/py310/Library/include"

The path should depend on where you install conda

Develop

Use

python -m pip install -r requirements.txt
python setup.py build_ext -i --use-cython --lib-path "D:\conda\envs\py310\Library\lib\archive.lib" --include-path "D:\conda\envs\py310\Library\include"

and so on
