Arpy

This library can be used to access ar files from python. It's tested to work with python 3.5+ and pypy3. (for earlier pythons see version <2) Travis status:

It supports both GNU and BSD formats and exposes the archived files using the standard python file interface.

Usage

Standard file usage:

With context managers:

with arpy.Archive('file.ar') as ar:
    print("files: %s" % ar.namelist())
    with ar.open('content.txt') as f:
        print(f.read())

Via headers for duplicate names:

with arpy.Archive('file.ar') as ar:
    for header in ar.infolist():
        print("file: %s" % header.name)
        with ar.open(header) as f:
            print(f.read())

Or directly:

ar = arpy.Archive('file.ar'))
ar.read_all_headers()

# check all available files
ar.archived_files.keys()

# get the contents of the archived file
ar.archived_files[b'some_file'].read()

Stream / pipe / ... usage:

ar = arpy.Archive('file.ar'))
for f in ar:
    print("got file name: %s" % f.header.name)
    print("with contents: %s" % f.read())
