reputils

Small Python utilities packaged as a library. Currently includes helpers for assembling and sending emails (headers, MIME parts, attachments) with sane defaults, plus a small script used in CI to update a GitHub clones badge via a Gist.

• Source: https://github.com/vroomfondel/reputils
• PyPI: https://pypi.org/project/reputils/

Overview

This package exposes functionality under the reputils module. The main user‑facing component at present is reputils.MailReport providing:

• EmailAddress dataclass for parsing/formatting email addresses
• SMTPServerInfo configuration for SMTP host/port/TLS/etc.
• MRSendmail to compose and send text/HTML emails with optional attachments and headers

There is also a maintenance script scripts/update_badge.py that is run in GitHub Actions to update a Shields.io JSON endpoint with cumulative repository clone statistics.

Stack

• Language: Python (requires Python >= 3.12; CI uses Python 3.14)
• Packaging/build: Hatchling (pyproject.toml)
• Testing: pytest
• Lint/format: black, isort, mypy
• CI: GitHub Actions (tests/mypy workflow badge shown above) and a scheduled workflow to update a clones badge

Requirements

Runtime dependencies (see pyproject.toml / requirements.txt):

• loguru>=0.7.3
• pytz>=2025.2 (packaged as pytz==2025.2 in requirements.txt)
• python-dateutil==2.9.*

Development dependencies (see requirements-dev.txt):

• pytest, mypy, black, isort, pre-commit, and typing stubs for dateutil and pytz

Python version: >=3.12. The repo’s Makefile and CI use Python 3.14 locally/in CI.

Installation

Install from PyPI:

pip install reputils

From source (recommended for development):

git clone https://github.com/vroomfondel/reputils
cd reputils
make install

The make install target creates/uses a local .venv and installs dev requirements.

Usage

Basic send (text and/or HTML)

MRSendmail.send() now returns a tuple (raw_message: str, result: SendResult). The raw string contains the fully rendered RFC 5322 message (including the generated Message-ID header). Use the SendResult helper to check whether delivery succeeded for all recipients or to inspect per‑recipient failures.

from email import message_from_string
from reputils.MailReport import EmailAddress, SMTPServerInfo, MRSendmail

server = SMTPServerInfo(
    smtp_server="smtp.example.com",
    smtp_port=587,
    smtp_user="user@example.com",
    smtp_pass="app-password",
    use_start_tls=True,
)

mailer = MRSendmail(
    serverinfo=server,
    returnpath=EmailAddress(email="bounce@example.com", name="Mailer"),
    senderfrom=EmailAddress(email="noreply@example.com", name="No Reply"),
    subject="Hello from reputils",
)

mailer.add_to(EmailAddress.from_str("Alice <alice@example.com>"))

raw, res = mailer.send(
    txt="Plain text body",
    html="<p>HTML body</p>",
)

print("All recipients succeeded:", res.all_succeeded())
# Extract the Message-ID from the rendered message if you need it:
msg = message_from_string(raw)
print("Message-ID:", msg["Message-ID"])  # e.g. <20250101...@example.com>

Cc/Bcc, attachments, and additional headers

from pathlib import Path
from reputils.MailReport import EmailAddress, SMTPServerInfo, MRSendmail

# Create or reuse a mailer instance (example shown inline for completeness)
server = SMTPServerInfo(smtp_server="smtp.example.com", smtp_port=587, use_start_tls=True)
mailer = MRSendmail(
    serverinfo=server,
    returnpath=EmailAddress(email="bounce@example.com", name="Mailer"),
    senderfrom=EmailAddress(email="noreply@example.com", name="No Reply"),
    subject="Monthly report",
)

mailer.add_to(EmailAddress.from_str("Alice <alice@example.com>"))
mailer.add_cc(EmailAddress.from_str("Bob <bob@example.com>"))
mailer.add_bcc(EmailAddress.from_str("carol@example.com"))

raw, res = mailer.send(
    txt="Report attached.",
    files=[Path("/tmp/report.txt"), Path("/tmp/plot.png")],
    additional_headers={
        "X-Trace-ID": "12345",
        "List-Id": "example.list.example.com",
    },
)

if not res.all_succeeded():
    # Inspect per‑recipient SMTP errors (email, code, message)
    for email, code, message in res.get_all_errors():
        print(f"Failed: {email} -> {code} {message}")

Unicode (Umlauts/Accents) work out of the box

MailReport composes messages using UTF‑8 and quoted‑printable encodings for both headers and bodies. That means subjects, display names, and message content with Umlauts and other non‑ASCII characters are sent correctly (e.g. Ä Ö Ü ä ö ü ß, accents like é, ñ, ą, …).

Example:

from reputils.MailReport import EmailAddress, SMTPServerInfo, MRSendmail

server = SMTPServerInfo(smtp_server="smtp.example.com", smtp_port=587, use_start_tls=True)
mailer = MRSendmail(
    serverinfo=server,
    returnpath=EmailAddress(email="bounce@example.com", name="Mailer"),
    senderfrom=EmailAddress(email="noreply@example.com", name="München Prüfstelle"),
    subject="Status für Prüfstände – Größe ist größer",
)

mailer.add_to(EmailAddress(email="alice@example.com", name="Jörg Hübner"))

txt_body = "Hallo Jörg, die Größe ist größer als erwartet. Grüße aus München!"
html_body = "<p>Hallo Jörg, die Größe ist <b>größer</b> als erwartet. Grüße aus München!</p>"

raw, res = mailer.send(txt=txt_body, html=html_body)
assert res.all_succeeded()

No additional configuration is required; Python’s email package handles RFC 2047/2045 encoding under the hood, and reputils.MailReport sets sane UTF‑8 defaults.

SMTP and application‑level debug logging per send

from reputils.MailReport import SMTPServerInfo, MRSendmail, EmailAddress

server = SMTPServerInfo(smtp_server="smtp.example.com", smtp_port=587)
mailer = MRSendmail(serverinfo=server, returnpath=EmailAddress(email="bounce@example.com"))

# Low‑level smtplib debugging for this call
raw, res = mailer.send(txt="Hello", wants_smtp_level_debug=True)

# More verbose application‑level logging from MRSendmail for this call
raw, res = mailer.send(txt="Hello", wantsdebuglogging=True)

Logging configuration with Loguru (optional)

MailReport uses loguru for logging. To enable a reasonable default console configuration with a built‑in “skiplog” filter, call:

from reputils import configure_loguru_default_with_skiplog_filter

configure_loguru_default_with_skiplog_filter()

See also scripts/loguru_skiplog_config_example.py for a minimal example.

Scripts and Automation

• scripts/update_badge.py: Updates a Gist with clone history and a Shields.io JSON for a “Cumulative Clones” badge. This is executed by .github/workflows/update-clone-badge.yml on a schedule or manual dispatch.

Environment variables required by the script/CI workflow:

• GIST_TOKEN: GitHub token with permission to update the target Gist
• GIST_ID: ID of the Gist storing history and badge JSON
• REPO_TOKEN: GitHub token to read repository traffic stats
• GITHUB_REPOSITORY: full repo slug, e.g. owner/repository

Local ad‑hoc run:

GIST_TOKEN=... GIST_ID=... REPO_TOKEN=... GITHUB_REPOSITORY=vroomfondel/reputils \
python scripts/update_badge.py

Makefile Targets

Convenience tasks are provided via Makefile:

• make install – create .venv and install dev requirements
• make tests – run pytest
• make tcheck – run mypy type checks
• make lint – run black
• make isort – fix import order
• make prepare – run tests and pre‑commit checks
• make pypibuild – build distribution with hatchling/build
• make pypipush – upload to PyPI via hatch

Note: The Makefile activates .venv automatically for these targets when not running in GitHub Actions.

Running Tests

make tests

Pytest is configured via pytest.ini. Current tests are minimal (see tests/test_base.py).
