# pyproject-toml-validator Validate `pyproject.toml` files for Python projects against PEP 517/621 standards. ## What it does Checks your `pyproject.toml` for common mistakes across three areas: - **[project]** — name format (PEP 508), version, license (SPDX), classifiers, dependency specs, authors, dynamic fields - **[build-system]** — requires, build-backend validation, known backends - **[tool.*]** — ruff, mypy, pytest, black, isort section validation with tool-specific rules ### Rules (30+) | Category | Rules | Examples | |----------|-------|---------| | Project metadata (10) | Missing name/version, invalid name format, unknown fields, malformed requires-python, unknown classifiers, empty authors, name in dynamic | `name = "My Package!"` → invalid PEP 508 name | | Dependencies (4) | Duplicate deps, unpinned deps, overlapping optional groups | `requests` and `Requests` both listed | | Build system (4) | Missing requires/build-backend, empty requires, unknown fields | No `[build-system]` table | | Tool sections (12+) | Ruff select/ignore overlap, mypy type mismatches, black/ruff conflict, isort/ruff conflict, unusual line lengths, invalid target versions | `[tool.ruff.lint] select = ["E501"]` + `ignore = ["E501"]` | ### Output formats - **text** — human-readable with severity icons (❌ ⚠️ ℹ️) - **json** — structured with summary counts - **summary** — one-line PASS/WARN/FAIL ### Exit codes - `0` — no errors (warnings/info allowed) - `1` — errors found (or `--strict` with any issue) - `2` — file not found or parse error ## Commands ### validate Full validation of all sections. ```bash python3 scripts/pyproject_validator.py validate pyproject.toml python3 scripts/pyproject_validator.py validate --format json pyproject.toml python3 scripts/pyproject_validator.py validate --strict pyproject.toml ``` ### project Validate only the `[project]` table. ```bash python3 scripts/pyproject_validator.py project pyproject.toml ``` ### build Validate only `[build-system]`. ```bash python3 scripts/pyproject_validator.py build pyproject.toml ``` ### tools Validate only `[tool.*]` sections (ruff, mypy, pytest, black, isort). ```bash python3 scripts/pyproject_validator.py tools --min-severity warning pyproject.toml ``` ## Options | Option | Values | Default | Description | |--------|--------|---------|-------------| | `--format` | text, json, summary | text | Output format | | `--min-severity` | error, warning, info | info | Filter by minimum severity | | `--strict` | flag | off | Exit 1 on any issue | ## Requirements - Python 3.11+ (uses `tomllib` from stdlib) - Falls back to built-in simple TOML parser on Python 3.10 ## Examples ```bash # Quick check python3 scripts/pyproject_validator.py validate pyproject.toml # CI pipeline python3 scripts/pyproject_validator.py validate --strict --format summary pyproject.toml # Check only tool configs python3 scripts/pyproject_validator.py tools --format json pyproject.toml # Filter noise python3 scripts/pyproject_validator.py validate --min-severity warning pyproject.toml ```
