Verified usage

Verified import paths — ran on the pinned version, not inferred.

Archive

✓ from arpy import Archive

Open an existing ar file and list its members.

from arpy import Archive with Archive('test.ar') as archive: for entry in archive: print(entry.name, entry.size)

Debug

Known issues

gotchaThe Archive class context manager does not close the file on __exit__ in some versions; manually call .close() if needed.

fix

Explicitly call archive.close() after use, or upgrade to 2.3.0+.

affects: <2.3.0

gotchaWriting archives: the write() method expects bytes, not str. Passing a string will raise a TypeError.

fix

Ensure data is bytes: archive.write(entry_name, b'data').

affects: all

breakingIn version 2.0.0, the API changed from old-style (archive = Archive('file'); archive.read()) to context manager. Old code will break.

fix

Use 'with Archive(...) as archive:' pattern. See docs.

affects: <=1.x

Errors

Common errors & fixes

AttributeError: module 'arpy' has no attribute 'Archive'

Importing incorrectly, e.g., 'import arpy' then using arpy.Archive instead of from arpy import Archive.

fix

Use 'from arpy import Archive'.

TypeError: write() argument must be a bytes-like object, not 'str'

Passing a string to Archive.write() instead of bytes.

fix

Encode string to bytes: archive.write('file.txt', 'content'.encode()).

FileNotFoundError: [Errno 2] No such file or directory: 'test.ar'

Trying to open a nonexistent archive for reading.

fix

Check the file path exists, or create a new archive with mode='w'.
