# 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` 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.



```python

from email import message_from_string

from reputils 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 "))



raw, res = mailer.send(

    txt="Plain text body",

    html="
HTML body
",

)



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



```python

from pathlib import Path

from reputils 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 "))

mailer.add_cc(EmailAddress.from_str("Bob "))

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:



```python

from reputils 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 = "
Hallo Jörg, die Größe ist größer als erwartet. Grüße aus München!
"



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` sets sane UTF‑8 defaults.



### SMTP and application‑level debug logging per send



```python

from reputils 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:



```python



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`).
