sarj-lint-configs 0.9.2

Maximally-strict ruff + pyright + ESLint configs for sarj-ai Python/TypeScript projects.

sarj-lint-configs

Ships the maximally-strict ruff / pyright / ESLint configs from sarj-ai/standards as a pip-installable package.

uv add --dev sarj-lint-configs
uv run sarj-lint-configs sync --only ruff      # writes .ruff-strict.toml
uv run sarj-lint-configs sync --only pyright   # writes .pyright-strict.json
uv run sarj-lint-configs sync --only eslint    # writes eslint.strict.mjs
uv run sarj-lint-configs check .                # runs every Python/SQL/IaC custom registry

Polyglot repositories can route the Python and TypeScript configs to their respective tool roots in one canonical sync:

uv run sarj-lint-configs sync \
  --python-dest python \
  --typescript-dest typescript \
  --force

Use the same command with --check in CI or a Git hook to detect drift without writing to the worktree.

The check command discovers every rule from the exact registry versions installed with this package: sarj-python-lint==0.26.0, sarj-sql-lint==0.5.0, and sarj-iac-lint==0.3.0. Files and recursively discovered directory contents are routed to the applicable registry by suffix. The command is deliberately zero-tolerance: it does not accept suppression baselines that a change could inflate to conceal new findings.

For commit-time feedback, pin Lefthook and install the hook during setup:

uv add --dev lefthook==2.1.10 sarj-lint-configs==0.9.1
uv run lefthook install

# lefthook.yml
min_version: 2.1.10
assert_lefthook_installed: true
pre-commit:
  jobs:
    - name: strict config drift
      run: uv run --frozen sarj-lint-configs sync --check
      fail_text: "Strict configs drifted. Re-run sync --force, stage the result, and retry."
    - name: sarj standards
      run: uv run --frozen sarj-lint-configs check -- {staged_files}
      fail_text: "Standards checks failed. Fix the issue, stage the result, and retry."

Do not copy the runner into consumer repositories. Keeping it inside the wheel ensures the CLI implementation and its exact registry dependencies upgrade as one tested unit.

The bundled ESLint config requires @sarj/eslint-plugin@2.16.0, which contains every custom TypeScript rule referenced by the config.

Then reference the synced file:

# pyproject.toml
[tool.ruff]
extend = ".ruff-strict.toml"

// pyrightconfig.json
{ "extends": ".pyright-strict.json" }

// eslint.config.mjs
import strict from "./eslint.strict.mjs";
export default [...strict];

Re-run sync with --force after upgrading. Programmatic access via from sarj_lint_configs import RUFF_STRICT, PYRIGHT_STRICT, ESLINT_STRICT (returns pathlib.Path into the wheel).

0.8.0 — PLC2701 moved out of ruff

PLC2701 import-private-name is now in the ignore list. It cannot tell a private name of ours from a private name of a dependency's: its exemption is "same top-level package", so from livekit.agents.inference_runner import _InferenceRunner — an API livekit made private in 1.6.6, with no public replacement — is flagged identically to a first-party helper someone forgot to export. Ruff has no configuration surface that separates them.

The check is replaced by SARJ048 in sarj-python-lint ≥ 0.19.0, which resolves the imported module against your project tree and fires only on first-party modules:

- repo: https://github.com/sarj-ai/standards
  rev: python-v0.19.0
  hooks:
    - id: sarj-no-first-party-private-import

If you are not running the sarj-python-lint hooks, re-enable PLC2701 in your own [tool.ruff.lint] extend-select — an over-firing check beats no check.

Attribute access (session._stt) is unchanged: ruff's SLF001 and pyright's reportPrivateUsage both still fire, and neither can make the first/third-party distinction. Both configs carry the rationale and the escape hatches inline.
