Overview
========

Apply a consistent format to your ``pyproject.toml`` file with comment support. See
`changelog here <https://github.com/tox-dev/toml-fmt/blob/main/pyproject-fmt/CHANGELOG.md>`_.


Recent Changes
~~~~~~~~~~~~~~~~

- 📝 docs(pyproject-fmt): overhaul the formatting reference by `@gaborbernat <https://github.com/gaborbernat>`_ in
  `#366 <https://github.com/tox-dev/toml-fmt/pull/366>`_ <a id="2.22.0"></a>

Philosophy
----------
This tool aims to be an *opinionated formatter*, with similar objectives to `black <https://github.com/psf/black>`_.
This means it deliberately does not support a wide variety of configuration settings. In return, you get consistency,
predictability, and smaller diffs.

Use
---

Via ``CLI``
~~~~~~~~~~~

`pyproject-fmt <https://pypi.org/project/pyproject-fmt>`_ is a CLI tool that needs a Python interpreter (version 3.10 or higher) to run. We recommend
either `pipx <https://pypi.org/project/pipx>`_ or `uv <https://pypi.org/project/uv>`_ to install pyproject-fmt into an isolated environment. This has the added benefit that
later you will be able to upgrade pyproject-fmt without affecting other parts of the system. We provide a method for
``pip`` too here, but we discourage that path if you can:


    .. code-block:: bash

        # install uv per https://docs.astral.sh/uv/#getting-started
        uv tool install pyproject-fmt
        pyproject-fmt --help


Via ``pre-commit`` hook
~~~~~~~~~~~~~~~~~~~~~~~

See `pre-commit/pre-commit <https://github.com/pre-commit/pre-commit>`_ for instructions, sample ``.pre-commit-config.yaml``:

.. code-block:: yaml

    - repo: https://github.com/tox-dev/pyproject-fmt
      # Use the sha / tag you want to point at
      # or use `pre-commit autoupdate` to get the latest version
      rev: ""
      hooks:
        - id: pyproject-fmt

Via Python
~~~~~~~~~~

You can use ``pyproject-fmt`` as a Python module to format TOML content programmatically.

.. code-block:: python

    from pyproject_fmt import run

    # Format a pyproject.toml file and return the exit code
    exit_code = run(["path/to/pyproject.toml"])

The ``run`` function accepts command-line arguments as a list and returns an exit code (0 for success, non-zero for
failure).


The ``tool.pyproject-fmt`` table is used when present in the ``pyproject.toml`` file:

.. code-block:: toml

    [tool.pyproject-fmt]

    # After how many columns split arrays/dicts into multiple lines and wrap long strings;
    # use a trailing comma in arrays to force multiline format instead of lowering this value
    column_width = 120

    # Number of spaces for indentation
    indent = 2

    # Keep full version numbers (e.g., 1.0.0 instead of 1.0) in dependency specifiers
    keep_full_version = false

    # Automatically generate Python version classifiers based on requires-python
    # Set to false to disable automatic classifier generation
    generate_python_version_classifiers = true

    # Maximum Python version for generating version classifiers
    max_supported_python = "3.14"

    # Table format: "short" collapses sub-tables to dotted keys, "long" expands to [table.subtable] headers
    table_format = "short"

    # Extra newlines between sub-tables in the same group (e.g. "\n" for one blank line between sub-tables)
    sub_table_spacing = ""

    # Extra newlines between root table groups (e.g. "\n" for one blank line, "\n\n" for two)
    separate_root_table = "\n"

    # List of tables to force expand regardless of table_format setting
    expand_tables = []

    # List of tables to force collapse regardless of table_format or expand_tables settings
    collapse_tables = []

    # List of key patterns to skip string wrapping (supports wildcards like *.parse or tool.bumpversion.*)
    skip_wrap_for_keys = []

If not set they will default to values from the CLI.

Shared configuration file
-------------------------

You can place formatting settings in a standalone ``pyproject-fmt.toml`` file instead of (or in addition to) the
``[tool.pyproject-fmt]`` table. This is useful for monorepos or when you want to share the same configuration across
multiple projects without duplicating it in each ``pyproject.toml``.

The formatter searches for ``pyproject-fmt.toml`` starting from the directory of the file being formatted and walking up
to the filesystem root. The first match wins. You can also pass an explicit path via ``--config``:

.. code-block:: bash

    pyproject-fmt --config /path/to/pyproject-fmt.toml pyproject.toml

The shared config file uses the same keys as the ``[tool.pyproject-fmt]`` table, but without the table header:

.. code-block:: toml

    column_width = 120
    indent = 2
    table_format = "short"
    sub_table_spacing = ""
    separate_root_table = "\n"
    max_supported_python = "3.14"

When both a shared config file and a ``[tool.pyproject-fmt]`` table exist, per-file settings from the
``[tool.pyproject-fmt]`` table take precedence over the shared config file.


Python version classifiers
--------------------------

This tool will automatically generate the ``Programming Language :: Python :: 3.X`` classifiers for you. To do so it
needs to know the range of Python interpreter versions you support:

- The lower bound can be set via the ``requires-python`` key in the ``pyproject.toml`` configuration file (defaults to
  the oldest non end of line CPython at the time of the release).
- The upper bound, by default, will assume the latest stable release of CPython at the time of the release, but can be
  changed via CLI flag or the config file.

Table formatting
----------------

.. note::

    Table formatting options are available in version 2.12.0 and later.

You can control how sub-tables are formatted in your ``pyproject.toml`` file. There are two formatting styles:

**Short format (collapsed)** - The default behavior where sub-tables are collapsed into dotted keys. Use this for a
compact representation:

.. code-block:: toml

    [project]
    name = "myproject"
    urls.homepage = "https://example.com"
    urls.repository = "https://github.com/example/myproject"
    scripts.mycli = "mypackage:main"

**Long format (expanded)** - Sub-tables are expanded into separate ``[table.subtable]`` sections. Use this for
readability when tables have many keys or complex values:

.. code-block:: toml

    [project]
    name = "myproject"

    [project.urls]
    homepage = "https://example.com"
    repository = "https://github.com/example/myproject"

    [project.scripts]
    mycli = "mypackage:main"

Table spacing
~~~~~~~~~~~~~

The ``sub_table_spacing`` and ``separate_root_table`` options control the blank lines inserted between tables. Each
option takes a string of ``\n`` characters where each ``\n`` adds one blank line:

- ``sub_table_spacing`` (default ``""``) controls spacing between sub-tables within the same group. For example,
  between ``[tool.ruff]`` and ``[tool.ruff.lint]``. Set to ``"\n"`` to add a blank line between sub-tables.
- ``separate_root_table`` (default ``"\n"``) controls spacing between different root table groups. For example,
  between ``[project]`` and ``[tool.ruff]``.

.. code-block:: toml

    [tool.pyproject-fmt]
    sub_table_spacing = "\n"  # Add blank line between sub-tables
    separate_root_table = "\n"  # One blank line between root table groups (default)

Configuration priority
~~~~~~~~~~~~~~~~~~~~~~

The formatting behavior is determined by a priority system that allows you to set a global default while overriding
specific tables:

1. **collapse_tables** - Highest priority, forces specific tables to be collapsed regardless of other settings
2. **expand_tables** - Medium priority, forces specific tables to be expanded
3. **table_format** - Lowest priority, sets the default behavior for all tables not explicitly configured

This three-tier approach lets you fine-tune formatting for specific tables while maintaining a consistent default.
For example:

.. code-block:: toml

    [tool.pyproject-fmt]
    table_format = "short"  # Collapse most tables
    expand_tables = ["project.entry-points"]  # But expand entry-points

Specificity rules
~~~~~~~~~~~~~~~~~

Table selectors follow CSS-like specificity rules: more specific selectors win over less specific ones. When
determining whether to collapse or expand a table, the formatter checks from most specific to least specific until it
finds a match.

For example, with this configuration:

.. code-block:: toml

    [tool.pyproject-fmt]
    table_format = "long"  # Expand all tables by default
    collapse_tables = ["project"]  # Collapse project sub-tables
    expand_tables = ["project.optional-dependencies"]  # But expand this specific one

The behavior will be:

- ``project.urls`` → collapsed (matches ``project`` in collapse_tables)
- ``project.scripts`` → collapsed (matches ``project`` in collapse_tables)
- ``project.optional-dependencies`` → expanded (matches exactly in expand_tables, more specific than ``project``)
- ``tool.ruff.lint`` → expanded (no match in collapse/expand, uses table_format default)

This allows you to set broad rules for parent tables while making exceptions for specific sub-tables. The specificity
check walks up the table hierarchy: for ``project.optional-dependencies``, it first checks if
``project.optional-dependencies`` is in collapse_tables or expand_tables, then checks ``project``, then falls back to
the table_format default.

Supported tables
~~~~~~~~~~~~~~~~

The following sub-tables can be formatted with this configuration:

**Project tables:**

- ``project.urls`` - Project URLs (homepage, repository, documentation, changelog)
- ``project.scripts`` - Console script entry points
- ``project.gui-scripts`` - GUI script entry points
- ``project.entry-points`` - Custom entry point groups
- ``project.optional-dependencies`` - Optional dependency groups

**Tool tables:**

- ``tool.ruff.format`` - Ruff formatter settings
- ``tool.ruff.lint`` - Ruff linter settings
- Any other tool sub-tables

**Array of tables:**

- ``project.authors`` - Can be inline tables or ``[[project.authors]]``
- ``project.maintainers`` - Can be inline tables or ``[[project.maintainers]]``
- Any ``[[table]]`` entries throughout the file

Array of tables (``[[table]]``) are automatically collapsed to inline arrays when each inline table fits within the
configured ``column_width``. For example:

.. code-block:: toml

    # Before
    [[tool.commitizen.customize.questions]]
    type = "list"

    [[tool.commitizen.customize.questions]]
    type = "input"

    # After (with table_format = "short")
    [tool.commitizen]
    customize.questions = [{ type = "list" }, { type = "input" }]

If any inline table exceeds ``column_width``, the array of tables remains in ``[[...]]`` format to maintain
readability and TOML 1.0.0 compatibility (inline tables cannot span multiple lines).

String wrapping
---------------

By default, the formatter wraps long strings that exceed the column width using line continuations. However, some strings such as regex patterns should not be wrapped because wrapping can break their functionality.

You can configure which keys should skip string wrapping using the ``skip_wrap_for_keys`` option:

.. code-block:: toml

    [tool.pyproject-fmt]
    skip_wrap_for_keys = ["*.parse", "*.regex", "tool.bumpversion.*"]

Pattern matching
~~~~~~~~~~~~~~~~

The ``skip_wrap_for_keys`` option supports glob-like patterns:

- **Exact match**: ``tool.bumpversion.parse`` matches only that specific key
- **Wildcard suffix**: ``*.parse`` matches any key ending with ``.parse`` (e.g., ``tool.bumpversion.parse``, ``project.parse``)
- **Wildcard prefix**: ``tool.bumpversion.*`` matches any key under ``tool.bumpversion`` (e.g., ``tool.bumpversion.parse``, ``tool.bumpversion.serialize``)
- **Global wildcard**: ``*`` skips wrapping for all strings

Examples: ``["*.parse", "*.regex"]`` to preserve regex fields, ``["tool.bumpversion.*"]`` for a specific tool section,
or ``["*"]`` to skip all string wrapping.

``pyproject-fmt`` is an opinionated formatter, much like `black <https://github.com/psf/black>`_ is for Python code.
The tool intentionally provides minimal configuration options because the goal is to establish a single standard format
that all ``pyproject.toml`` files follow.

**Benefits of this approach:**

- Less time configuring tools
- Smaller diffs when committing changes
- Easier code reviews since formatting is never a question

While a few key options exist (``column_width``, ``indent``, ``table_format``, ``sub_table_spacing``,
``separate_root_table``), the tool does not expose dozens of toggles. You get what the maintainers have chosen to be the
right balance of readability, consistency, and usability. The ``column_width`` setting controls when arrays are split
into multiple lines and when string values are wrapped using line continuations.

General Formatting
------------------

These rules apply uniformly across the entire ``pyproject.toml`` file.

Table Ordering
~~~~~~~~~~~~~~

Tables are reordered into a consistent structure:

1. ``[build-system]``
2. ``[project]``
3. ``[dependency-groups]``
4. ``[tool.*]`` sections in the order:

   1. Build backends: ``poetry``, ``poetry-dynamic-versioning``, ``pdm``, ``setuptools``, ``distutils``,
      ``setuptools_scm``, ``hatch``, ``flit``, ``scikit-build``, ``meson-python``, ``maturin``, ``pixi``,
      ``whey``, ``py-build-cmake``, ``sphinx-theme-builder``, ``uv``
   2. Builders: ``cibuildwheel``, ``nuitka``
   3. Linters/formatters: ``autopep8``, ``black``, ``yapf``, ``djlint``, ``ruff``, ``isort``, ``flake8``,
      ``pycln``, ``nbqa``, ``pylint``, ``repo-review``, ``codespell``, ``docformatter``, ``pydoclint``,
      ``interrogate``, ``tomlsort``, ``check-manifest``, ``check-sdist``, ``check-wheel-contents``, ``deptry``,
      ``vulture``, ``pyproject-fmt``, ``typos``, ``bandit``
   4. Type checkers: ``mypy``, ``pyrefly``, ``pyright``, ``ty``, ``django-stubs``
   5. Testing: ``pytest``, ``pytest_env``, ``pytest-enabler``, ``coverage``
   6. Task runners: ``doit``, ``spin``, ``tox``
   7. Release tools: ``bumpversion``, ``commitizen``, ``jupyter-releaser``, ``semantic_release``, ``tbump``,
      ``towncrier``, ``vendoring``
   8. Any other ``tool.*`` in alphabetical order

5. Any other tables (alphabetically)

String Quotes
~~~~~~~~~~~~~

All strings use double quotes by default. Single quotes are only used when the value contains double quotes:

.. code-block:: toml

    # Before
    name = 'my-package'
    description = "He said \"hello\""

    # After
    name = "my-package"
    description = 'He said "hello"'

Key Quotes
~~~~~~~~~~

TOML keys are normalized to the simplest valid form. Keys that are valid bare keys (containing only
``A-Za-z0-9_-``) have redundant quotes stripped. Single-quoted (literal) keys that require quoting are
converted to double-quoted (basic) strings with proper escaping. This applies to all keys: table headers,
key-value pairs, and inline table keys:

.. code-block:: toml

    # Before
    [tool."ruff"]
    "line-length" = 120
    lint.per-file-ignores.'tests/*' = ["S101"]

    # After
    [tool.ruff]
    line-length = 120
    lint.per-file-ignores."tests/*" = ["S101"]

Backslashes and double quotes within literal keys are escaped during conversion:

.. code-block:: toml

    # Before
    lint.per-file-ignores.'path\to\file' = ["E501"]

    # After
    lint.per-file-ignores."path\\to\\file" = ["E501"]

Array Formatting
~~~~~~~~~~~~~~~~

Arrays are formatted based on line length, trailing comma presence, and comments:

.. code-block:: toml

    # Short arrays stay on one line
    keywords = ["python", "toml"]

    # Long arrays that exceed column_width are expanded and get a trailing comma
    dependencies = [
        "requests>=2.28",
        "click>=8.0",
    ]

    # Trailing commas signal intent to keep multiline format
    classifiers = [
        "Development Status :: 4 - Beta",
    ]

    # Arrays with comments are always multiline
    lint.ignore = [
        "E501",  # Line too long
        "E701",
    ]

**Multiline formatting rules:**

An array becomes multiline when any of these conditions are met:

1. **Trailing comma present** - A trailing comma signals intent to keep multiline format
2. **Exceeds column width** - Arrays longer than ``column_width`` are expanded (and get a trailing comma added)
3. **Contains comments** - Arrays with inline or leading comments are always multiline

String Wrapping
~~~~~~~~~~~~~~~

Strings that exceed ``column_width`` (including the key name and ``" = "`` prefix) are wrapped into multi-line
triple-quoted strings using line continuations:

.. code-block:: toml

    # Before (exceeds column_width)
    description = "A very long description that goes beyond the configured column width limit"

    # After
    description = """\
      A very long description that goes beyond the \
      configured column width limit\
      """

Wrapping prefers breaking at spaces and at ``" :: "`` separators (common in Python classifiers). Strings inside inline
tables are never wrapped. Strings that contain actual newlines are preserved as multi-line strings without adding line
continuations. Use ``skip_wrap_for_keys`` to prevent wrapping for specific keys.

Table Formatting
~~~~~~~~~~~~~~~~

Sub-tables can be formatted in two styles controlled by ``table_format``:

**Short format** (collapsed to dotted keys):

.. code-block:: toml

    [project]
    urls.homepage = "https://example.com"
    urls.repository = "https://github.com/example/project"

**Long format** (expanded to table headers):

.. code-block:: toml

    [project.urls]
    homepage = "https://example.com"
    repository = "https://github.com/example/project"

**Table spacing:**

By default, different table groups (e.g. ``[project]`` and ``[tool.ruff]``) are separated by a blank line, while
sub-tables within the same group (e.g. ``[tool.ruff]`` and ``[tool.ruff.lint]``) are kept compact with no blank line
between them. You can control this with ``sub_table_spacing`` and ``separate_root_table``. Each option takes a string of
``\n`` characters where each ``\n`` adds one blank line. For example, setting ``sub_table_spacing = "\n"`` adds a blank
line between sub-tables:

.. code-block:: toml

    [tool.ruff]
    line-length = 120

    [tool.ruff.lint]
    select = ["E", "W"]


Comment Preservation
~~~~~~~~~~~~~~~~~~~~

All comments are preserved during formatting:

- **Inline comments** - Comments after a value on the same line stay with that value
- **Leading comments** - Comments on the line before an entry stay with the entry below
- **Block comments** - Multi-line comment blocks are preserved

**Inline comment alignment:**

Inline comments within arrays are aligned independently per array, based on that array's longest value:

.. code-block:: toml

    # Before - comments at inconsistent positions
    lint.ignore = [
      "COM812", # Conflict with formatter
      "CPY", # No copyright statements
      "ISC001",   # Another rule
    ]

    # After - comments align to longest value in this array
    lint.ignore = [
      "COM812",  # Conflict with formatter
      "CPY",     # No copyright statements
      "ISC001",  # Another rule
    ]

Table-Specific Handling
-----------------------

Beyond general formatting, each table has specific key ordering and value normalization rules.

``[build-system]``
~~~~~~~~~~~~~~~~~~

The :pep:`517` / :pep:`518` table that declares how your project is built. See the
`packaging specification <https://packaging.python.org/en/latest/specifications/pyproject-toml/#build-system-table>`_.

Keys are ordered ``build-backend`` → ``requires`` → ``backend-path``, and ``requires`` is normalized and sorted.


**Key ordering:** ``build-backend`` → ``requires`` → ``backend-path``

**Value normalization:**

- ``requires``: dependencies normalized per :pep:`508` and sorted alphabetically by package name
- ``backend-path``: entries sorted alphabetically

.. code-block:: toml

    # Before
    [build-system]
    requires = ["setuptools >= 45", "wheel"]
    build-backend = "setuptools.build_meta"

    # After
    [build-system]
    build-backend = "setuptools.build_meta"
    requires = ["setuptools>=45", "wheel"]

``[project]``
~~~~~~~~~~~~~

The :pep:`621` core metadata table. See the
`packaging specification <https://packaging.python.org/en/latest/specifications/pyproject-toml/#the-project-table>`_.

Keys follow the canonical metadata order; name, dependencies, classifiers, and keywords are normalized and sorted.


**Key ordering:** ``name`` → ``version`` → ``import-names`` → ``import-namespaces`` → ``description`` →
``readme`` → ``keywords`` → ``license`` → ``license-files`` → ``maintainers`` → ``authors`` →
``requires-python`` → ``classifiers`` → ``dynamic`` → ``dependencies`` → ``optional-dependencies`` →
``urls`` → ``scripts`` → ``gui-scripts`` → ``entry-points``

**Field normalizations:**

``name``
    Converted to canonical format (lowercase with hyphens): ``My_Package`` → ``my-package``

``description``
    Whitespace normalized: multiple spaces collapsed, consistent spacing after periods.

``license``
    License expression operators (``and``, ``or``, ``with``) uppercased: ``MIT or Apache-2.0`` →
    ``MIT OR Apache-2.0``

``requires-python``
    Whitespace removed: ``>= 3.9`` → ``>=3.9``

``keywords``
    Deduplicated (case-insensitive) and sorted alphabetically.

``dynamic``
    Sorted alphabetically.

``import-names`` / ``import-namespaces``
    Semicolon spacing normalized (``foo;bar`` → ``foo; bar``), entries sorted alphabetically.

``classifiers``
    Deduplicated and sorted alphabetically.

``authors`` / ``maintainers``
    Sorted by name, then email. Keys within each entry ordered: ``name`` → ``email``.

**Dependency normalization:** every dependency array (``dependencies``, ``optional-dependencies.*``) is
normalized per :pep:`508` (spaces removed, redundant ``.0`` suffixes stripped unless
``keep_full_version = true``) and sorted alphabetically by canonical package name:

.. code-block:: toml

    # Before
    dependencies = ["requests >= 2.0.0", "click~=8.0"]

    # After
    dependencies = ["click>=8", "requests>=2"]

**Optional-dependency extra names** are normalized to lowercase with hyphens:

.. code-block:: toml

    # Before
    [project.optional-dependencies]
    Dev_Tools = ["pytest"]

    # After
    [project.optional-dependencies]
    dev-tools = ["pytest"]

**Python version classifiers** are generated automatically from ``requires-python`` and
``max_supported_python``. Disable with ``generate_python_version_classifiers = false``:

.. code-block:: toml

    # With requires-python = ">=3.10" and max_supported_python = "3.14"
    classifiers = [
        "Programming Language :: Python :: 3 :: Only",
        "Programming Language :: Python :: 3.10",
        "Programming Language :: Python :: 3.11",
        "Programming Language :: Python :: 3.12",
        "Programming Language :: Python :: 3.13",
        "Programming Language :: Python :: 3.14",
    ]

**Entry points:** inline tables within ``entry-points`` are expanded to dotted keys:

.. code-block:: toml

    # Before
    entry-points.console_scripts = { mycli = "mypackage:main" }

    # After
    entry-points.console_scripts.mycli = "mypackage:main"

**Authors / maintainers** can be inline tables or an expanded array of tables (controlled by ``table_format``,
``expand_tables``, and ``collapse_tables``):

.. code-block:: toml

    # Short format (inline)
    authors = [{ name = "Alice", email = "alice@example.com" }]

    # Long format (array of tables)
    [[project.authors]]
    name = "Alice"
    email = "alice@example.com"

``[dependency-groups]``
~~~~~~~~~~~~~~~~~~~~~~~

The :pep:`735` table for named groups of development dependencies. See the
`packaging specification <https://packaging.python.org/en/latest/specifications/dependency-groups/>`_.

Groups are ordered ``dev`` → ``test`` → ``type`` → ``docs`` → others alphabetically; each group is normalized and sorted.


**Key ordering:** ``dev`` → ``test`` → ``type`` → ``docs`` → others alphabetically

**Value normalization:**

- all dependencies normalized per :pep:`508`
- sorted with regular dependencies first, then ``include-group`` entries

.. code-block:: toml

    # Before
    [dependency-groups]
    dev = [{ include-group = "test" }, "ruff>=0.4", "mypy>=1"]

    # After
    [dependency-groups]
    dev = ["mypy>=1", "ruff>=0.4", { include-group = "test" }]

``[tool.poetry]``
~~~~~~~~~~~~~~~~~

`Poetry <https://python-poetry.org/>`_ is a Python dependency management and packaging tool. See its
`pyproject.toml reference <https://python-poetry.org/docs/pyproject/>`_.

Covers both Poetry 1.x (legacy metadata under ``[tool.poetry]``) and Poetry 2.x (metadata moved to ``[project]``,
Poetry-specific keys still here). Metadata is ordered by section, Poetry-specific inline tables get canonical key
order, and set-semantic arrays are sorted while order-significant ones are preserved.


**Top-level key ordering:**

1. Identity: ``name`` → ``version`` → ``description`` → ``package-mode``
2. License & authorship: ``license`` → ``authors`` → ``maintainers``
3. Documentation: ``readme`` → ``homepage`` → ``repository`` → ``documentation``
4. Discovery: ``keywords`` → ``classifiers``
5. Packaging contents: ``packages`` → ``include`` → ``exclude`` → ``build``
6. Dependencies (sub-tables): ``dependencies`` → ``dev-dependencies`` → ``group`` → ``extras``
7. Entry points / distribution: ``scripts`` → ``plugins`` → ``urls`` → ``source``
8. Poetry runtime constraints: ``requires-poetry`` → ``requires-plugins`` → ``build-constraints``

**Sub-table key ordering:**

``[tool.poetry.dependencies]`` / ``[tool.poetry.dev-dependencies]`` / per-group dependencies
    ``python`` first (interpreter constraint), all other package names alphabetized.

``[tool.poetry.group.<name>]``
    ``optional`` → ``include-groups`` → ``dependencies``.

``[tool.poetry.extras]``, ``[tool.poetry.scripts]``, ``[tool.poetry.urls]``, ``[tool.poetry.plugins.*]``, ``[tool.poetry.requires-plugins]``, ``[tool.poetry.build-constraints]``
    Keys alphabetized.

``[tool.poetry.build]``
    ``script`` → ``generate-setup-file``.

``[[tool.poetry.source]]``
    Each entry's keys ordered ``name`` → ``url`` → ``priority`` → ``links`` → ``indexed``, with the deprecated
    ``default`` and ``secondary`` keys placed last. Array order itself is preserved (priority ordering is
    semantically significant).

**Sorted arrays:**

- ``keywords``, ``classifiers``: deduplicated (case-insensitive) and sorted alphabetically.
- ``exclude``: sorted alphabetically.
- ``[tool.poetry.extras]`` values (each ``extras.<name>``): sorted alphabetically.
- ``[tool.poetry.group.<name>.include-groups]``: sorted alphabetically.
- Per-dependency ``extras`` arrays (in ``dependencies``, ``dev-dependencies``, per-group dependencies,
  ``requires-plugins``, ``build-constraints``): sorted alphabetically.

**Preserved as written** (order is semantically significant): ``authors``, ``maintainers``, ``packages``,
``include``, ``readme`` (when an array), multi-constraint dependency arrays, and ``[[tool.poetry.source]]``
entries.

**Inline-table key ordering:** when a Poetry-specific inline table is detected (via discriminator keys unique
to Poetry's schema), its keys are reordered:

- Sources (``{ priority = ... }``, ``{ secondary = ... }``, ``{ links = ... }``, ``{ indexed = ... }``):
  ``name`` → ``url`` → ``priority`` → ``links`` → ``indexed`` → ``default`` → ``secondary``.
- Git dependencies (``{ git = ... }``):
  ``git`` → ``branch`` → ``tag`` → ``rev`` → ``subdirectory`` → ``python`` → ``platform`` → ``markers`` →
  ``allow-prereleases`` → ``allows-prereleases`` → ``optional`` → ``extras`` → ``develop``.
- Path dependencies (``{ path = ... }``):
  ``path`` → ``develop`` → ``subdirectory`` → ``python`` → ``platform`` → ``markers`` → ``optional`` →
  ``extras``.
- File dependencies (``{ file = ... }``):
  ``file`` → ``subdirectory`` → ``python`` → ``platform`` → ``markers`` → ``optional`` → ``extras``.

Inline tables that don't match any Poetry-specific schema (for example ``[[project.authors]]`` inline form
``{ name = "...", email = "..." }``) are left untouched.

``[tool.pdm.*]``
~~~~~~~~~~~~~~~~

`PDM <https://pdm-project.org/latest/>`_ is a modern Python package and dependency manager. See its
`build configuration reference <https://pdm-project.org/latest/reference/build/>`_.

Top-level keys are ordered distribution → resolution → version → build → scripts → source → dev-dependencies →
publish → options; name and glob arrays are sorted, while source-entry order is preserved.


**Top-level key ordering:** distribution / package-type / plugins → resolution → version → build → scripts →
source → dev-dependencies → publish → options.

**Sub-table ordering** (collapsed to dotted keys):

- ``version``: ``source`` → ``path`` → ``getter`` → ``write_to`` → ``write_template`` → ``tag_regex`` →
  ``tag_filter`` → ``fallback_version`` → ``version_format``.
- ``build``: ``includes`` → ``excludes`` → ``source-includes`` → ``package-dir`` → ``is-purelib`` →
  ``run-setuptools`` → ``custom-hook`` → ``editable-backend``.
- ``[[tool.pdm.source]]`` (array of tables, order preserved): per-entry ``name`` → ``url`` → ``type`` →
  ``verify_ssl`` → ``include_packages`` → ``exclude_packages``.

**Sorted arrays:** ``plugins``, ``build.includes``, ``build.excludes``, ``build.source-includes``,
``resolution.excludes``, every ``dev-dependencies.<group>`` value array, and ``include_packages`` /
``exclude_packages`` inside source entries.

``[tool.setuptools]`` and ``[tool.setuptools_scm]``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

`setuptools <https://setuptools.pypa.io/en/latest/>`_ is a long-standing build backend and packaging library;
`setuptools_scm <https://setuptools-scm.readthedocs.io/en/latest/>`_ derives the package version from SCM tags. See
the setuptools `pyproject.toml reference <https://setuptools.pypa.io/en/latest/userguide/pyproject_config.html>`_
and the setuptools_scm `configuration reference <https://setuptools-scm.readthedocs.io/en/latest/config/>`_.

Keys in both tables are grouped (discovery → data → metadata → deprecated); name and glob arrays are sorted, while
literal lists like ``packages`` are preserved.


``[tool.setuptools]`` top-level key ordering (grouped):

1. Packaging discovery: ``py-modules`` → ``packages.find.*`` / ``packages.find-namespace.*`` → ``packages`` →
   ``package-dir``
2. Package data: ``include-package-data`` → ``package-data`` → ``exclude-package-data``
3. Dynamic metadata: ``dynamic``
4. Extensions / build customization: ``ext-modules`` → ``cmdclass``
5. Distribution metadata: ``platforms`` → ``provides`` → ``obsoletes`` → ``license-files``
6. Data files: ``data-files``
7. Deprecated / obsolete (pushed last): ``script-files`` → ``namespace-packages`` → ``zip-safe`` →
   ``eager-resources`` → ``dependency-links``

``[tool.setuptools.packages.find]`` / ``[tool.setuptools.packages.find-namespace]`` inner ordering: ``where`` →
``include`` → ``exclude`` → ``namespaces``.

``[tool.setuptools.package-data]`` / ``[tool.setuptools.exclude-package-data]`` / ``[tool.setuptools.data-files]``
ordering: the catch-all ``"*"`` pattern always goes first, then the other package patterns alphabetically; each
value (an array of glob patterns) is sorted alphabetically.

``[tool.setuptools.dynamic]`` ordering: field names alphabetized. Inline-table directives (e.g.
``version = { attr = "pkg.__version__" }`` or ``readme = { file = "README.md", content-type = "text/markdown" }``)
get their keys ordered ``attr`` → ``file`` → ``content-type``.

**Sorted arrays:**

- ``py-modules``, ``platforms``, ``provides``, ``obsoletes``, ``script-files``, ``namespace-packages``,
  ``eager-resources``: alphabetized.
- ``packages.find.include`` / ``packages.find.exclude`` / ``packages.find-namespace.*``: alphabetized.
- Values inside ``package-data`` / ``exclude-package-data`` / ``data-files`` tables: alphabetized.

**Preserved as written** (order is meaningful): ``packages`` (literal list, first match wins),
``license-files`` (PEP 639 concatenation order), and everything under ``[[tool.setuptools.ext-modules]]``
(compiler and linker argv arrays).

``[tool.setuptools_scm]`` key ordering (grouped):

1. Version output: ``version_file`` → ``version_file_template``
2. Version computation: ``version_scheme`` → ``local_scheme`` → ``version_cls`` → ``normalize``
3. Root discovery: ``root`` → ``relative_to`` → ``fallback_root`` → ``parent`` →
   ``search_parent_directories`` → ``dist_name``
4. Tag / parse: ``tag_regex`` → ``parse`` → ``parentdir_prefix_version`` → ``fallback_version``
5. Nested SCM-specific tables: ``scm.git.pre_parse`` → ``scm.git.describe_command``
6. Deprecated (pushed last): ``git_describe_command`` (use ``scm.git.describe_command``) → ``write_to`` (use
   ``version_file``) → ``write_to_template`` (use ``version_file_template``) → ``version_class`` (use
   ``version_cls``) → ``template``

``[tool.hatch.*]``
~~~~~~~~~~~~~~~~~~

`Hatch <https://hatch.pypa.io/latest/>`_ is a modern, extensible Python project manager built around the Hatchling
build backend. See its `build configuration reference <https://hatch.pypa.io/latest/config/build/>`_.

Keys across the many ``[tool.hatch.*]`` sub-tables are grouped (version → metadata → build → publish → workspace →

   ``extra-metadata``, etc.) → sdist target (``include``, ``exclude``, ``force-include``, ``support-legacy``,
   ``strict-naming``).
4. Publish: ``publish.index.disable`` → ``publish.index.repos`` → ``publish.index``.
5. Workspace: ``workspace.members`` → ``workspace.exclude``.
6. Environments (``envs.<name>.*``): each environment's keys follow ``type`` → ``template`` → ``detached`` →
   ``description`` → ``platforms`` → ``python`` → ``path`` → ``installer`` → ``skip-install`` →
   ``system-packages`` → ``dev-mode`` → ``features`` → ``dependencies`` → ``extra-dependencies`` →
   ``extra-args`` → ``pre-install-commands`` → ``post-install-commands`` → ``env-include`` → ``env-exclude``
   → ``env-vars`` → ``scripts`` → ``matrix`` → ``matrix-name-format`` → ``overrides``.

**Sorted arrays:**

- Build: ``include``, ``exclude``, ``force-include``, ``artifacts``, ``packages``, ``sources``,
  ``dev-mode-dirs``, and the matching ``build.targets.wheel.*`` / ``build.targets.sdist.*`` arrays.
- Environments: per-env ``dependencies``, ``extra-dependencies``, ``features``, ``platforms``,
  ``env-include``, ``env-exclude``, ``pre-install-commands``, ``post-install-commands``.
- Workspace: ``members``, ``exclude``.

``scripts`` and ``env-vars`` sub-tables under each environment have their inner keys alphabetized.

**Preserved as written:** build-hook order and matrix entry order (both carry semantic meaning).

``[tool.scikit-build]``
~~~~~~~~~~~~~~~~~~~~~~~

`scikit-build-core <https://scikit-build-core.readthedocs.io/en/latest/>`_ is a CMake-based build backend for

``strict-config``) → ``build`` → ``cmake`` → ``ninja`` → ``sdist`` → ``wheel`` → ``install`` → ``editable`` →
``logging`` / ``messages`` → ``metadata`` → ``search`` → ``generate`` (array of tables) → ``overrides``
(array of tables).

**Sorted arrays:** ``include``, ``exclude``, ``packages``, ``files``, ``targets``, ``components``,

.. code-block:: toml

    # Before
    [tool.uv.sources]
    zebra = { git = "..." }
    alpha = { path = "..." }

    # After
    [tool.uv.sources]
    alpha = { path = "..." }
    zebra = { git = "..." }

**pip subsection:** ``[tool.uv.pip]`` follows the same rules, with arrays like ``extra``, ``no-binary-package``,
``no-build-package``, ``reinstall-package``, and ``upgrade-package`` sorted alphabetically.

``[tool.cibuildwheel]``
~~~~~~~~~~~~~~~~~~~~~~~

`cibuildwheel <https://cibuildwheel.pypa.io/en/stable/>`_ builds Python wheels across platforms in CI. See its
`options reference <https://cibuildwheel.pypa.io/en/stable/options/>`_.

Keys are ordered selection → build config → build phases → test phases → platform images → per-platform sub-tables
→ ``overrides``; set-semantic arrays are sorted, while argv-like lists are preserved.


**Key ordering:** selection (``build``, ``skip``, ``test-skip``, ``archs``, ``enable``,
``free-threaded-support``) → build configuration (``build-frontend``, ``build-verbosity``, ``config-settings``,
``dependency-versions``, ``environment``, ``environment-pass``) → build phases (``before-all``,
``before-build``, ``repair-wheel-command``) → test phases (``before-test``, ``test-command``,

(``manylinux-*-image``, ``musllinux-*-image``) → ``container-engine`` → per-platform sub-tables (``linux``,
``macos``, ``windows``, ``android``, ``ios``, ``pyodide``) → ``overrides`` last.

Per-platform sub-tables follow the same inner ordering. ``[[tool.cibuildwheel.overrides]]`` entries place
``select`` first (required), then the regular cibuildwheel keys; the array order itself is preserved (later
overrides win).

**Sorted arrays:** ``enable``, ``test-extras``, ``test-groups``.

**Preserved as written:** most other array-valued keys (``test-requires``, ``before-all``, ``test-command``,
the various ``environment*`` fields) are CLI argv or ordered lists.

``[tool.autopep8]``
~~~~~~~~~~~~~~~~~~~

`autopep8 <https://github.com/hhatto/autopep8>`_ automatically formats Python code to conform to PEP 8. See its
`configuration reference <https://github.com/hhatto/autopep8#pyproject-toml>`_.

Keys are ordered length/indent → mode → rules → behavior; rule lists are sorted.


**Key ordering:** length/indent → mode (``in-place``, ``recursive``, ``diff``, ``list-fixes``) → rules
(``ignore``, ``select``, ``exclude``) → behavior.

**Sorted arrays:** ``ignore``, ``select``, ``exclude``.

``[tool.black]``
~~~~~~~~~~~~~~~~

`Black <https://black.readthedocs.io/en/stable/>`_ is an opinionated Python code formatter. See its
`configuration reference <https://black.readthedocs.io/en/stable/usage_and_configuration/the_basics.html>`_.

Keys follow Black's option grouping; ``target-version`` and ``enable-unstable-feature`` arrays are alphabetized.


**Key ordering:**

1. ``required-version`` → ``target-version`` → ``line-length``
2. File selection: ``include`` → ``extend-exclude`` → ``force-exclude`` → ``exclude``
3. Behavior: ``skip-string-normalization`` → ``skip-magic-trailing-comma`` → ``preview`` → ``unstable`` →
   ``enable-unstable-feature`` → ``fast`` → ``workers``
4. Output: ``color`` → ``verbose`` → ``quiet``

**Sorted arrays:** ``target-version`` (so ``py39`` precedes ``py310``), ``enable-unstable-feature``.

The ``include`` / ``exclude`` family are regex strings, not arrays, so they're left as-is.

``[tool.yapf]``
~~~~~~~~~~~~~~~

`YAPF <https://github.com/google/yapf>`_ is a configurable Python code formatter from Google. See its
`configuration reference <https://github.com/google/yapf#knobs>`_.

A single flat table: ``based_on_style`` comes first (it sets the defaults), then the rest in a fixed order.


**Key ordering:** ``based_on_style`` first (sets defaults), then ``column_limit``, ``indent_width``,
``continuation_indent_width``, then the remaining keys alphabetized.

~~~~~~~~~~~~~~~

`Ruff <https://docs.astral.sh/ruff/>`_ is a fast Python linter and formatter written in Rust. See its
`settings reference <https://docs.astral.sh/ruff/settings/>`_.

Keys follow Ruff's option grouping (global → paths → behavior → output → ``format`` → ``lint``); rule-code, path, and
name arrays are sorted with natural ordering (``RUF1`` < ``RUF9`` < ``RUF10``).


**Key ordering:**

1. Global settings: ``required-version`` → ``extend`` → ``target-version`` → ``line-length`` →
   ``indent-width`` → ``tab-size``
2. Path settings: ``builtins`` → ``namespace-packages`` → ``src`` → ``include`` → ``extend-include`` →
   ``exclude`` → ``extend-exclude`` → ``force-exclude`` → ``respect-gitignore``

``[tool.isort]``
~~~~~~~~~~~~~~~~

`isort <https://pycqa.github.io/isort/>`_ sorts and organizes Python imports. See its
`configuration options <https://pycqa.github.io/isort/docs/configuration/options.html>`_.

``profile`` comes first (it sets the defaults everything else overrides), then output style, known sources,
separation, skip patterns, and import edits; name lists are sorted, while sequence-sensitive lists are preserved.


**Key ordering:**

1. ``profile``: sets defaults that the keys below override
2. Output style: line, wrap, indent, and multi-line options
3. Known sources: ``sections`` → ``default_section`` → ``known_standard_library`` →

``[tool.mypy]``
~~~~~~~~~~~~~~~

`mypy <https://mypy.readthedocs.io/en/stable/>`_ is a static type checker for Python. See its
`configuration reference <https://mypy.readthedocs.io/en/stable/config_file.html>`_.

Covers all documented mypy options plus the ``[[tool.mypy.overrides]]`` array of tables, reordered to match mypy's
configuration reference; set-semantic arrays are sorted, while ``plugins`` and ``mypy_path`` are preserved.


**Top-level key ordering** (sectioned):

1. Import discovery: ``mypy_path`` → ``files`` → ``modules`` → ``packages`` → ``exclude`` →
   ``exclude_gitignore`` → ``namespace_packages`` → ``explicit_package_bases`` → ``ignore_missing_imports`` →
   ``follow_untyped_imports`` → ``follow_imports`` → ``follow_imports_for_stubs`` → ``python_executable`` →
   ``no_site_packages`` → ``no_silence_site_packages``
2. Platform configuration: ``python_version`` → ``platform`` → ``always_true`` → ``always_false``
3. Disallow dynamic typing: ``disallow_any_unimported`` → ``disallow_any_expr`` → ``disallow_any_decorated`` →
   ``disallow_any_explicit`` → ``disallow_any_generics`` → ``disallow_subclassing_any``
4. Untyped definitions and calls: ``disallow_untyped_calls`` → ``untyped_calls_exclude`` →
   ``disallow_untyped_defs`` → ``disallow_incomplete_defs`` → ``check_untyped_defs`` →
   ``disallow_untyped_decorators``
5. None and Optional: ``implicit_optional`` → ``strict_optional``
6. Configuring warnings: ``warn_redundant_casts`` → ``warn_unused_ignores`` → ``warn_no_return`` →
   ``warn_return_any`` → ``warn_unreachable`` → ``deprecated_calls_exclude``
7. Suppressing errors: ``ignore_errors``
8. Miscellaneous strictness: ``allow_untyped_globals`` → ``allow_redefinition`` → ``local_partial_types`` →
   ``disable_error_code`` → ``enable_error_code`` → ``extra_checks`` → ``implicit_reexport`` →
   ``strict_equality`` → ``strict_bytes`` → ``strict``
9. Configuring error messages: ``show_error_context`` → ``show_column_numbers`` → ``show_error_end`` →
   ``hide_error_codes`` → ``show_error_code_links`` → ``pretty`` → ``color_output`` → ``error_summary`` →
   ``show_absolute_path``
10. Incremental mode: ``incremental`` → ``cache_dir`` → ``sqlite_cache`` → ``cache_fine_grained`` →
    ``skip_version_check`` → ``skip_cache_mtime_checks``
11. Advanced options: ``plugins`` → ``pdb`` → ``show_traceback`` → ``raise_exceptions`` →
    ``custom_typing_module`` → ``custom_typeshed_dir`` → ``warn_incomplete_stub`` → ``native_parser``
12. Report generation: ``any_exprs_report`` → ``cobertura_xml_report`` → ``html_report`` →
    ``linecount_report`` → ``linecoverage_report`` → ``lineprecision_report`` → ``txt_report`` →
    ``xml_report`` → ``xslt_html_report`` → ``xslt_txt_report``
13. Miscellaneous: ``junit_xml`` → ``junit_format`` → ``scripts_are_modules`` → ``warn_unused_configs`` →
    ``verbosity``
14. ``overrides`` last.

**Overrides entry key ordering:** in each ``[[tool.mypy.overrides]]`` entry, ``module`` comes first
(required), then per-module overridable keys in the same logical grouping as the parent table (import behavior,
platform markers, disallow dynamic typing, untyped defs/calls, optional handling, warnings, suppression,
miscellaneous strictness).

**Sorted arrays:**

- Top-level: ``files``, ``modules``, ``packages``, ``exclude``, ``always_true``, ``always_false``,
  ``untyped_calls_exclude``, ``deprecated_calls_exclude``, ``disable_error_code``, ``enable_error_code``.
- Inside overrides entries: ``module`` (when an array of patterns), ``always_true``, ``always_false``,
  ``disable_error_code``, ``enable_error_code``.

**Preserved as written:** ``plugins`` (run in declared order; reordering changes behavior) and ``mypy_path``
(a search path with priority semantics).

**Inline-table handling:** when ``[[tool.mypy.overrides]]`` collapses to ``overrides = [{...}, {...}]`` under
the default ``table_format = "short"``, key order inside each entry is normalized via discriminators unique to
mypy (``disable_error_code`` / ``enable_error_code`` / ``ignore_missing_imports`` / ``follow_untyped_imports``
/ ``ignore_errors`` / ``warn_unused_ignores`` / ``disallow_untyped_defs`` / ``check_untyped_defs``). The arrays
inside each inline entry are sorted in place, so ``disable_error_code = [...]`` is alphabetized whether the
override is expanded or collapsed.

.. code-block:: toml

    # Before
    [[tool.mypy.overrides]]
    ignore_missing_imports = true
    disable_error_code = ["import-untyped", "attr-defined"]
    module = "third_party.*"

    # After
    [tool.mypy]
    overrides = [
      { module = "third_party.*", ignore_missing_imports = true, disable_error_code = [ "attr-defined", "import-untyped" ] },
    ]

``[tool.pyrefly]``
~~~~~~~~~~~~~~~~~~

`Pyrefly <https://pyrefly.org/>`_ is Meta's fast Python type checker and language server, written in Rust. See its

`configuration reference <https://microsoft.github.io/pyright/#/configuration>`_ and the basedpyright
`config-files reference <https://docs.basedpyright.com/latest/configuration/config-files/>`_.

Keys are ordered platform → mode flags → paths → strict-flavor toggles → ``defineConstant`` → ``report*`` rules
(alphabetized) → ``executionEnvironments``; path arrays are sorted.


**Key ordering:**

1. Platform / interpreter: ``pythonVersion`` → ``pythonPlatform`` → ``pythonPath`` → ``venv`` → ``venvPath``
   → ``typeshedPath`` → ``stubPath``
2. Mode flags: ``typeCheckingMode`` → ``strict`` → ``failOnWarnings`` → ``useLibraryCodeForTypes``
3. Paths: ``include`` → ``exclude`` → ``ignore`` → ``extraPaths``
4. Strict-flavor toggles: ``strictListInference``, ``strictDictionaryInference``, ``strictSetInference``,

   ``analyzeUnannotatedFunctions``, ``disableBytesTypePromotions``, ``deprecateTypingAliases``
5. ``defineConstant``
6. All ``report*`` rules, alphabetized
7. ``executionEnvironments`` (last)

The ``report*`` rules (70+ in pyright; basedpyright adds more) are collected from the input and inserted
alphabetically rather than hardcoded, so new diagnostic rules don't require formatter changes.

``addopts`` and ``pythonpath`` are preserved.


**Key ordering:** pytest itself → discovery → CLI arguments → markers/parametrize → warnings → doctest →
output → logging (capture / CLI / file) → JUnit XML → cache and tmp_path → assertion / faulthandler.

``collect_ignore_glob``, ``python_files``, ``python_classes``, ``python_functions``, ``markers``,
``filterwarnings``, ``doctest_optionflags``, ``usefixtures``, ``required_plugins``.

**Preserved as written:** ``addopts`` (CLI argv, order matters) and ``pythonpath`` (a search path with
priority semantics).

.. code-block:: toml

    # Before
    [tool.pytest.ini_options]
    log_cli_level = "INFO"
    markers = [ "slow: marks tests as slow", "fast: marks tests as fast" ]
    addopts = [ "--strict-markers", "-ra" ]
    testpaths = [ "tests" ]

~~~~~~~~~~~~~~~~~~~

`coverage.py <https://coverage.readthedocs.io/en/latest/>`_ measures code coverage of Python programs. See its
`configuration reference <https://coverage.readthedocs.io/en/latest/config.html>`_.

Keys follow coverage.py's workflow phases (run → paths → report → output formats) with related options kept adjacent;
set-semantic arrays are sorted.


**Key ordering:** coverage.py's workflow phases:

1. **Run phase** (``run.*``): data collection

   - Source selection: ``source`` → ``source_pkgs`` → ``source_dirs``
   - File filtering: ``include`` → ``omit``
   - Measurement: ``branch`` → ``cover_pylib`` → ``timid``
   - Execution context: ``command_line`` → ``concurrency`` → ``context`` → ``dynamic_context``
   - Data management: ``data_file`` → ``parallel`` → ``relative_files``
   - Extensions: ``plugins``
   - Debugging: ``debug`` → ``debug_file`` → ``disable_warnings``
   - Other: ``core`` → ``patch`` → ``sigterm``

2. **Paths** (``paths.*``): path mapping between source locations

3. **Report phase** (``report.*``): general reporting

   - Thresholds: ``fail_under`` → ``precision``
   - File filtering: ``include`` → ``omit`` → ``include_namespace_packages``
   - Line exclusion: ``exclude_lines`` → ``exclude_also``
   - Partial branches: ``partial_branches`` → ``partial_also``

     ``skip_empty``
   - ``json.*``: ``output`` → ``pretty_print`` → ``show_contexts``
   - ``lcov.*``: ``output`` → ``line_checksums``
   - ``xml.*``: ``output`` → ``package_depth``

Related options stay adjacent: ``include`` / ``omit``, ``exclude_lines`` / ``exclude_also``,
``partial_branches`` / ``partial_also``, and ``skip_covered`` / ``skip_empty``.

**Sorted arrays:**

Run phase
  ``source``, ``source_pkgs``, ``source_dirs``, ``include``, ``omit``, ``concurrency``, ``plugins``, ``debug``,
  ``disable_warnings``

Report phase

    report.exclude_also = ["if TYPE_CHECKING:"]

``[tool.tox]``
~~~~~~~~~~~~~~

`tox <https://tox.wiki/en/stable/>`_ automates and standardizes testing across multiple Python environments. See
its `configuration reference <https://tox.wiki/en/stable/config.html>`_.

A ``[tool.tox]`` block in ``pyproject.toml`` reuses the ``tox-toml-fmt`` rules, so it is formatted identically to a
standalone ``tox.toml``.


Reuses the rules from ``tox-toml-fmt``: alias normalization (``envlist`` → ``env_list``, ``setenv`` →
``set_env``, etc.), canonical key ordering for the root table and every env table, PEP 508 requirement
normalization and sorting in ``deps`` and ``constraints``, sorted ``pass_env`` (inline-table entries first),
version-aware ``env_list`` sorting (``py313`` before ``py312`` before ``py311``), and inline-table reordering
for ``replace``, ``prefix``, ``product``, and ``value`` directives.

See the ``tox-toml-fmt`` documentation for the full schema and per-key behavior; the only difference here is
the namespace (``tool.tox`` instead of the root table).

``[tool.bumpversion]``
~~~~~~~~~~~~~~~~~~~~~~

`bump-my-version <https://callowayproject.github.io/bump-my-version/>`_ (the successor to bumpversion) updates
version strings across files and tags releases. See its `configuration reference
<https://callowayproject.github.io/bump-my-version/reference/configuration/>`_.

**Key ordering:** identity (``current_version``) → format (``parse``, ``serialize``, ``search``, ``replace``,
``regex``, ``ignore_missing_*``) → tag (``tag``, ``sign_tags``, ``tag_name``, ``tag_message``) → commit
(``allow_dirty``, ``commit``, ``commit_args``, ``message``, ``moveable_tags``) → behavior → ``files`` /
``parts`` (arrays of tables, last).

``[tool.commitizen]``
~~~~~~~~~~~~~~~~~~~~~

`Commitizen <https://commitizen-tools.github.io/commitizen/>`_ enforces conventional commits and automates version
bumps and changelogs. See its
`configuration reference <https://commitizen-tools.github.io/commitizen/config/configuration_file/>`_.

**Key ordering:** tag/version → assets → version source → repo → commit parser → branches → publish →
changelog → remote.

**Sorted arrays:** ``version_variables``, ``version_toml``, ``assets``, ``exclude_commit_patterns``.

``[tool.towncrier]``
~~~~~~~~~~~~~~~~~~~~

`towncrier <https://towncrier.readthedocs.io/en/stable/>`_ builds release notes from news-fragment files. See its
`configuration reference <https://towncrier.readthedocs.io/en/stable/configuration.html>`_.

Keys are ordered package identity → news location → rendering → behavior → ``type`` / ``section``; the ``ignore``
glob list is sorted, while changelog display order is preserved.


**Key ordering:** package identity (``name``, ``version``, ``package``, ``package_dir``) → news location
(``directory``, ``filename``, ``start_string``, ``template``, ``title_format``, ``issue_format``,
``underlines``) → rendering (``wrap``, ``all_bullets``, ``single_file``, ``orphan_prefix``,
``create_eof_newline``, ``create_add_extension``) → behavior (``ignore``) → ``type`` and ``section`` (arrays
of tables, last).

``[[tool.towncrier.type]]`` entries get keys ordered ``directory`` → ``name`` → ``showcontent``;
``[[tool.towncrier.section]]`` entries get ``path`` → ``name`` → ``showcontent``. Array order is preserved
(display order in the rendered changelog).

**Sorted arrays:** ``ignore`` (file globs to skip).

Other Tables
~~~~~~~~~~~~

Any unrecognized tables are preserved and reordered according to standard table ordering rules. Keys within unknown
tables are not reordered or normalized.
