tomte

A library that wraps many useful tools (linters, analysers, etc) to keep Python code clean, secure, well-documented and optimised.

Essentially does nothing else but pinning multiple packages to compatible versions, for consistency across many projects and simplicity of use.

Extremely (!) opinionated by design!

Wrapped tools

• black
• bandit
• isort
• flake8
• mypy
• safety
• darglint
• vulture
• pylint
• docs (various mkdocs libraries)
• tests (various pytest libraries)
• tox
• liccheck

To install, for instance black, simply specify tomte[black]==VERSION, where VERSION is the latest version, and then use black CLI as required.

Shipped configs

Since 0.7.0, tomte ships canonical linter configurations as packaged resources. Reach them from a tox env (or any tooling) via:

from tomte.configs import PYLINTRC, MYPY_INI, ISORT_CFG, FLAKE8_CFG, DARGLINT_CFG, BANDIT_YAML, SAFETY_POLICY

Each constant is a pathlib.Path to the file inside the installed wheel. Typical use:

[testenv:pylint]
commands = pylint --rcfile={envsitepackagesdir}/tomte/configs/pylintrc <paths>

tomte tox runtime wrapper

Since 0.7.0, tomte tox renders the canonical tox.ini (shipped at tomte/configs/tox.ini) at runtime, reading per-repo identity from [tool.tomte] in the consumer's pyproject.toml and a slim [tomte-extensions] section in their local tox.ini. The rendered file is ephemeral — nothing generated lives on disk between runs. Invoke as a drop-in replacement: tomte tox -e <env>.

Per-repo settings in [tool.tomte] (TOML in pyproject.toml): packages_paths, pytest_targets[_extra|_exclude], service_specific_packages[_extra], service_public_id, known_first_party, open_autonomy_version, open_aea_version, check_handlers_ignores, check_dependencies_extra_excludes, upstream_pins, gitleaks_extra_paths, gitleaks_extra_regexes, tomte_dep_pin. Most defaults auto-derive from packages.json.

Per-repo settings in [tomte-extensions] (raw INI in local tox.ini, for things that don't fit cleanly in TOML): extra_deps, extra_pylint_disables, extra_pylint_ignored_modules, extra_testenvs — multi-line continuation values that configparser preserves verbatim.

Scope. tomte tox targets AEA agent repos — the homogeneous fleet that ships packages/valory/ skills + agents + services and bootstraps via the autonomy CLI. Framework repos (open-aea, open-autonomy) keep their own hand-written tox.ini and consume the canonical configs directly (from tomte.configs import PYLINTRC, MYPY_INI, …) via --rcfile= / --config= flags.

Pytest plugin (opt-in)

Tomte declares a pytest11 entry-point plugin in pyproject.toml that ships fleet-canonical pytest defaults: the integration and e2e markers, plus an ignore::DeprecationWarning:aea.*: filter. Pytest auto-loads pytest11 plugins, so the plugin module is imported in any environment where tomte is installed — but the plugin is silent by default; it registers nothing unless the consumer opts in:

# tox.ini (or pyproject.toml [tool.pytest.ini_options], or pytest.ini)
[pytest]
tomte_defaults = true

Truthy spellings: true, 1, yes, on (case-insensitive). Without opt-in, non-fleet tomte[black] / tomte[mypy] consumers see no config injection.

Development:

Install deps:

Install poetry. Install development dependencies before running maintenance scripts:

poetry install --with dev

Upgrading versions

Use the script directly (fully automated, no manual pin editing):

1. Run poetry run python bump_to_latest.py

This command automatically:

• Resolves latest compatible versions for <4,>=3.10 support.
• Applies strict == pins with Poetry.
• Falls back to the highest resolver-compatible version when the absolute latest conflicts.
• Bumps package version (patch by default) in pyproject.toml, tomte/__init__.py, and tests/test_tomte.py.
• Regenerates poetry.lock.

Useful flags:

• --dry-run
• --bump-version none|patch|minor|major
• --no-lock

Name

"The Swedish hustomte (house elf/gnome) is a quiet little guy, dressed mostly in gray and red, living at your house or farmsted helping out by taking care of things around the house and keep everyone safe."

"A tomte and his son enjoying quiet company of the cat. Illustration by Rolf Lidberg."

Release guide:

Finish edits and ensure dev dependencies are installed (poetry install --with dev), then run poetry run python bump_to_latest.py, then poetry run pytest -q, then poetry build, then rm -rf dist, then poetry publish --build --username=<username> --password=<password>.
