usenet 0.1.0a2

NNTP client and newsgroup harvesting toolkit for Python.

usenet

NNTP client and newsgroup-harvesting toolkit for Python. Read and post articles, discover public servers, and harvest groups into a text corpus.

Works on Python 3.9–3.13: nntplib was removed from the standard library in 3.13 (PEP 594), so the standard-nntplib backport is pulled in automatically there.

Install

pip install usenet
# optional: anti-bot + Wayback transport for the legacy server-list scrapers
pip install usenet[scrape]

Quickstart

Read a group:

from datetime import timedelta
from usenet import UsenetServer

with UsenetServer("news.eternal-september.org") as server:
    for article in server.get_new_news("comp.lang.python", since=timedelta(days=7)):
        print(article.subject, article.author, article.date)
        print(article.text)

Post an article (most servers need a free account):

from usenet import UsenetServer

with UsenetServer("news.eternal-september.org", user="login", pswd="secret") as server:
    server.post("this is a test", subject="hello", group="misc.test")

Server discovery

A curated, offline list ships with the package:

from usenet import get_known_servers

for s in get_known_servers():
    print(s.url, s._can_post)

The legacy directory scrapers in usenet.scrappers are a secondary "refresh once" path; their source sites are mostly dead, so with usenet[scrape] installed requests fall back to the Wayback Machine. See examples/.

Dataset

dataset.py harvests a newsgroup into a JSONL corpus (one article per line) for publishing to the Hugging Face Hub. See docs/dataset.md.

python dataset.py comp.lang.python --days 30 --out comp.lang.python.jsonl

Testing

pip install -e .[test]
pytest test/

The unit tests are offline; they exercise article parsing, post framing, the bundled server list, and scraper HTML parsing against fixtures.
