These conventions apply to all new-API code and are stricter than the v1 sections above. The full design record (rationale, settled-decision logs, dated amendments) lives in untracked `docs/superpowers/specs/`; this section is the enforceable subset. **A commit that establishes or amends one of these conventions must update this section in the same commit** — grep-driven staleness sweeps miss paraphrased prose (see Workflow above), so write-time maintenance is the mechanism, audits are the backstop. + +- **Module layout**: every new module is underscore-private (`_types.py`, `_lexicon.py`, `_policy.py`, `_locale.py`, `_render.py`, `_pipeline/`, `_parser.py`, plus the facade layer: `_facade.py`, `_config_shim.py`). The public import surface is exactly `nameparser` and `nameparser.locales`; `nameparser/__init__.py` holds re-exports and `__all__` only — no logic. Since the M11 swap, the old paths are import-path-preserving re-exports: `nameparser.parser` re-exports the `_facade` `HumanName`, `nameparser.config` re-exports the `_config_shim` names (`Constants`, `CONSTANTS`, `SetManager`, `TupleManager`, `RegexTupleManager`); the `config/` DATA modules stay the vocabulary source through 2.x. The whole facade layer is deleted in 3.0. +- **Facade layer** (`_facade.py`, `_config_shim.py`): the v1-compat `HumanName`/`Constants` over the core. Key mechanisms: `Constants._generation` dirty-tracking (every mutation bumps; facades resolve their `Parser` lazily via `_cached_parser(lexicon, policy)`); `Constants._snapshot()` mirrors `_lexicon._default_lexicon()` (equality-pinned); the facade pickles v1-SHAPED state (component lists, one `__setstate__` path for 1.4 and 2.x blobs; components rebuild via `replace()`, never a re-parse); `_V1_HOOKS` overrides warn once per subclass (#280). The compat contract is the migration spec's promise: warning-free 1.4 code behaves identically except release-log-classified fixes — `tools/differential/` (dev-only, not shipped) verifies this against 1.4-on-PyPI over a 486-name corpus. `parser.py:NNNN` citations throughout the 2.0 code refer to the PRE-swap v1 file, deleted at the M11 swap; resolve them with `git show 2d5d8c2:nameparser/parser.py`. +- **Layering is enforced by `tests/v2/test_layering.py`** (exact-module matching; `if TYPE_CHECKING:` imports don't count): `_types` imports nothing internal at module level — its rendering delegates import `_render` at call time; `_lexicon` and `_policy` sit above `_types` independently (`_lexicon` may import `nameparser.config.*` DATA modules only — vocabulary is single-sourced from the v1 data modules through 2.x, e.g. `config/maiden_markers.py`); `_locale` sits on `_lexicon`+`_policy` (plus `_types` for the shared pickle mixin); `_render` imports `_types` and `_lexicon` (for `Lexicon.default()` and `_normalize`); `_pipeline/*` imports `_types`+`_lexicon`+`_policy` plus in-package `_pipeline` helpers; `_parser` sits on everything except `_render`; the facade layer (`_facade`, `_config_shim`, `parser`, `config/__init__`, `__main__`) may import anything public plus `_render`; locale pack modules (`locales/*.py`) import `_locale`/`_lexicon`/`_policy` only, and the `locales/__init__` additionally lazy-imports its packs (PEP 562). Extend the test's `ALLOWED` table when adding a module. +- **Canonical field order** — the seven roles in `Role` enum declaration order, defined once and derived everywhere (properties, `as_dict`, reprs, `comparison_key`). Never restate the order literally. +- **Method organization**, fixed section order in every class: fields + `__post_init__` validation → alternative constructors → dunders (construction/equality → protocol → operators) → properties → public methods by concern (access → editing → comparison → rendering delegates) → private helpers last, except a helper serving exactly one section may sit at that section's head. Sanctioned deviation, facade layer only: `HumanName` and the shim `Constants` organize by v1 concern groups (`# -- render defaults --`, `# -- config / parsing --`, `# -- fields --`, ..., dunders and pickle last) — the classes mirror v1's own surface and die in 3.0; the canonical order still binds every core type. +- **Validation is eager and fail-loud**: every `raise` states the offending value, the expected form, and the fix. Exception taxonomy: wrong type — including wrong element type inside a collection, bare `str` where an iterable of strings is expected, or a `Mapping` where a plain iterable is expected — raises `TypeError`; well-typed but unacceptable values raise `ValueError`; failed enum lookups stay `ValueError` for any input (stdlib `EnumType` precedent). +- **Reprs are bounded**: render which fields deviate from a named baseline and by how much, never contents (`Lexicon(default + titles: +2)`). +- **Typing/docs**: `from __future__ import annotations`; `frozen=True, slots=True` on every public dataclass; strict-profile mypy flags via per-module overrides in pyproject (`strict = true` itself is not valid per-module). Docstrings state contracts in prose with **no doctest blocks** — `--doctest-modules` makes every example a test; behavior examples go to unit tests per the lean-docs rule. +- **Pickling**: v2 types must round-trip (`Parser` will be picklable by construction, and it holds a `Lexicon`). Every frozen type assigns `_guarded_getstate`/`_guarded_setstate` (`_types.py`) in its class body (`@dataclass(slots=True)` would override inherited pickle methods) — unpickling fails at the LOAD site on field-layout skew, and values are deliberately NOT re-validated (pickle is not a security boundary; canonical state comes from a validated instance). `Lexicon` keeps its own copy of the guard (layering) plus the `mappingproxy` slot rebuild; a new unpicklable slot type needs the same treatment plus a round-trip test. +- **One sanctioned global**: the (future) cached default `Parser`. Lazily cached FROZEN singletons (`Lexicon.default()`'s `functools.cache`, the future default parser) are constants, not state; any second piece of module-level MUTABLE state requires amending the conventions doc, on purpose, in review. Sanctioned exceptions, facade layer only: `_config_shim.CONSTANTS` (the v1 shared singleton, mutable by design) and `_facade._WARNED_SUBCLASSES` (the once-per-subclass hook-warning dedup set) — both deleted with the layer in 3.0. +- **Tests**: all v2 tests live in the `tests/v2/` package (its `conftest.py` overrides the v1 dual-run fixture — v2 code never reads shared `CONSTANTS`), one test module per source module plus cross-cutting `test_reprs.py` and `test_layering.py`, names stating behavior. Never assert `Lexicon.default()` contents; the narrow sourcing spot-checks in `test_default_sources_v1_vocabulary` that pin the v1→v2 migration contract (e.g. the flipped `particles_ambiguous` model) are the sanctioned exception. + ## Extension Patterns **Adding a scalar `Constants` attribute + `HumanName` kwarg** (e.g. `initials_separator`, `suffix_delimiter`): @@ -120,7 +138,7 @@ Each named attribute (`title`, `first`, etc.) is a `@property` that joins its co Add a dedicated `copy.deepcopy()` round-trip test for it too (see `test_regexes_deepcopy_roundtrip`/`test_nickname_delimiters_deepcopy_roundtrip` in `tests/test_constants.py`), not just reliance on conftest's autouse snapshot/restore exercising it incidentally. `TupleManager`/`RegexTupleManager.__getattr__` answer *any* unknown attribute lookup — dunder probes like `__deepcopy__` raise `AttributeError` (never answered as config keys), everything else still returns `self.get(attr)`/`EMPTY_REGEX` — so a new manager subtype or a `__getattr__` tweak can silently break `copy.deepcopy` (this bit `RegexTupleManager` before the dunder-lookup guard was added).

This page explains the model behind +that call: how a string becomes tokens and tokens become fields, +where configuration lives and why it is split the way it is, why +parsers are plain values, and what happens when a name is genuinely +ambiguous. The task pages all build on these four ideas. + +From string to name +-------------------- + +Every parse follows the same path: the input string is split into +tokens, each token is assigned one of the seven roles — ``title``, +``given``, ``middle``, ``family``, ``suffix``, ``nickname``, +``maiden`` — and every string you read off the result is computed +from those tokens at read time. + +Parsing ``"Dr. Juan Q. Xavier de la Vega III"`` produces eight +tokens. The first is ``Dr.`` with the ``title`` role; ``de``, ``la``, +and ``Vega`` each carry the ``family`` role, which is why +``name.family`` returns ``"de la Vega"`` — the field is a view that +joins the family-role tokens in order, not a stored string. + +Each token also records where it came from. A span is a pair of +character positions bounding the token in the original string: +``Dr.`` has span ``(0, 3)``, and ``name.original[0:3]`` is exactly +``"Dr."``. Internally, spans let the pipeline refer to a token by +position instead of by text. v1 re-found name pieces by searching for +matching text, so a name with a repeated word could make the parser +rewrite the wrong occurrence (`issue #100 +`_ and its +relatives); a position cannot be confused with a look-alike. + +:class:`~nameparser.ParsedName` is frozen: there is no attribute +assignment, ever. If a parse is almost right and you want to fix one +field, you call ``.replace()``, which returns a new +:class:`~nameparser.ParsedName` with that field changed and everything +else — tokens, spans, the rest of the roles — carried over unchanged. +``str()`` renders the default view; nothing about calling it mutates +the value you called it on. + +The three containers +--------------------- + +Every piece of nameparser configuration falls into exactly one of +three places, and which one is decided by a single question: what does +this setting vary with? + +* :class:`~nameparser.Lexicon` holds everything that varies by + **language**: the vocabulary — titles, particles, suffixes, + conjunctions, and the rest of the word lists the parser matches + against. +* :class:`~nameparser.Policy` holds everything that varies by + **data source or application**: the behavior switches — name order, + patronymic rules, delimiters, strip flags — anything that changes + how the pipeline runs, not what words it recognizes. +* :ref:`Rendering arguments ` cover everything + that varies by **output destination**: the ``spec`` you pass to + ``render(spec)``, or a keyword to ``initials()``/``capitalized()``. + +"Dean" is a common given name, so it is not in the default titles +vocabulary — but in some data it is more common as a title. Which +reading is right is a fact about the language and domain the names +come from, not about any one dataset or report: that makes it a +:class:`~nameparser.Lexicon` entry. A CRM that always exports "Family, Given" strings is a fact +about that one data source, not about the language of the names in +it — that's a :class:`~nameparser.Policy`. One particular report +wanting names formatted as "Family, Given" while every other consumer +of the same parsed data wants "Given Family" is a fact about where the +string is going next, decided at the moment you render it — that's a +rendering argument, not something baked into how the name was parsed. + +This replaces v1's single ``Constants`` object, which mixed all three +concerns — vocabulary, behavior, and output formatting — into one +mutable bag plus a ``string_format`` template string. Sorting a +setting into the right container is largely mechanical once you ask +the "varies by what?" question above; see :doc:`migrate` for the +attribute-by-attribute mapping from the old ``Constants`` to the new +containers. + +Parsers are values +-------------------- + +``parse()`` is a convenience function over a module-level default +:class:`~nameparser.Parser`. You only need to build your own +:class:`~nameparser.Parser` (directly, or via +:func:`~nameparser.parser_for`) when you want non-default vocabulary +or behavior — and when you do, build it once and reuse it. Constructing +a :class:`~nameparser.Parser` validates its configuration up front, so +it's cheap but not free; parsing individual names is the hot path, and +a :class:`~nameparser.Parser` is designed to be called many times +without reconstruction. + +:class:`~nameparser.Lexicon`, :class:`~nameparser.Policy`, +:class:`~nameparser.Parser`, and :class:`~nameparser.ParsedName` are +all frozen and hashable. That means they're safe to share across +threads without locking, safe to use as dict keys or cache keys, and +equality means exactly what it says — two :class:`~nameparser.Parser` +instances built from equal configuration are equal values, not merely +two objects that happen to behave the same. Every piece of +configuration in the 2.0 API is a frozen value — including the +module-level default parser itself. + +Honest ambiguity +------------------ + +Parsing never raises. Pass in a string that doesn't look like a name +at all, and you get back a :class:`~nameparser.ParsedName` with empty +fields, not an exception. The parser's job is to make a reasonable +call on real-world text, not to reject it. + +Some calls are irreducibly ambiguous — both readings are legitimate, +and no amount of rule-tuning resolves them without breaking some other +name. Those surface as entries on ``ParsedName.ambiguities`` instead +of being silently guessed away. The canonical example: a leading "Van" +in "Van Johnson" reads as a given name (that's the common case for +that shape), but "Van" is also a family-name particle in plenty of +other names, so the parse records a ``particle-or-given`` ambiguity +alongside its answer. You can inspect ``ambiguities`` to decide, case +by case, whether your data needs a second look. + +Tokens also carry tags — a second, independent label alongside their +role, recording how a token was classified rather than what part of +the name it belongs to — but only a handful of them are part of the +stable API: ``particle``, ``conjunction``, ``initial``, and ``joined``. +Any tag written with a namespace prefix, like ``vocab:...``, is +provenance information for debugging how a token got classified — it +can change shape between releases and isn't something to match against +in your own code. If you need to branch on how a token was +classified, branch on role or on one of the four stable tags above, +not on a namespaced one. diff --git a/docs/conf.py b/docs/conf.py index 6449d56d..e69d2547 100644 --- a/docs/conf.py +++ b/docs/conf.py @@ -36,6 +36,12 @@ 'sphinx.ext.viewcode', ] +# Declaration order is canonical in this codebase (Role order drives the +# seven-field order everywhere), so the reference lists members in +# source order, not alphabetically -- Lexicon's vocabulary grouping and +# Policy's field ordering match the customize.rst table. +autodoc_member_order = 'bysource' + # Add any paths that contain templates here, relative to this directory. templates_path = ['_templates'] @@ -139,7 +145,9 @@ # Add any paths that contain custom static files (such as style sheets) here, # relative to this directory.

Cannot include things that may be first names. -* :py:data:`~nameparser.config.FIRST_NAME_TITLES` - Titles that, when followed by a single name, that name is a first name, e.g. "King David". -* :py:data:`~nameparser.config.SUFFIX_ACRONYMS` - Pieces that come at the end of the name that may or may not have periods separating the letters, e.g. "m.d.". -* :py:data:`~nameparser.config.SUFFIX_NOT_ACRONYMS` - Pieces that come at the end of the name that never have periods separating the letters, e.g. "Jr.". -* :py:data:`~nameparser.config.SUFFIX_ACRONYMS_AMBIGUOUS` - Acronym suffixes from ``SUFFIX_ACRONYMS`` that also plausibly work as a given-name nickname on their own, e.g. "JD", "Ed". When one of these appears alone in parenthesis or quotes (e.g. ``'JEFFREY (JD) BRICKEN'``), it's kept as a nickname rather than reclassified as a suffix, since that's the more common reading in ambiguous, delimiter-only context (see the "Nickname Handling" section in the usage guide). -* :py:data:`~nameparser.config.CONJUNCTIONS` - Connectors like "and" that join the preceding piece to the following piece. -* :py:data:`~nameparser.config.PREFIXES` - Connectors like "del" and "bin" that join to the following piece but not the preceding, similar to titles but can appear anywhere in the name. -* :py:data:`~nameparser.config.CAPITALIZATION_EXCEPTIONS` - Dictionary of pieces that do not capitalize the first letter, e.g. "Ph.D". -* :py:data:`~nameparser.config.REGEXES` - Regular expressions used to find words, initials, nicknames, etc. - -Each set-valued constant comes with :py:func:`~nameparser.config.SetManager.add`, :py:func:`~nameparser.config.SetManager.remove`, and :py:func:`~nameparser.config.SetManager.discard` methods for tuning -the constants for your project. These methods automatically lower case and -remove punctuation to normalize them for comparison. The two dict-valued -constants (``CAPITALIZATION_EXCEPTIONS`` and ``REGEXES``) are edited with -normal dict operations. - -Adding Custom Nickname Delimiters -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -:py:meth:`~nameparser.parser.HumanName.parse_nicknames` recognizes delimiters -through two per-bucket collections: -:py:obj:`~nameparser.config.Constants.nickname_delimiters` (default: the -three built-ins -- ``quoted_word``, ``double_quotes`` and ``parenthesis``, -each resolved live from :py:attr:`~nameparser.config.Constants.regexes`, so -overriding e.g. ``CONSTANTS.regexes.parenthesis`` still works exactly as -before) and :py:obj:`~nameparser.config.Constants.maiden_delimiters` (empty -by default -- see "Routing to Maiden Name" below). - -To recognize an *additional* delimiter, add a compiled pattern to -``nickname_delimiters`` under any key, then re-run -:py:meth:`~nameparser.parser.HumanName.parse_full_name` to pick it up: + >>> from nameparser import Lexicon, Parser + >>> lex = Lexicon.default().add(titles={"dean"}) + >>> Parser(lexicon=lex).parse("Dean Robert Johns").title + 'Dean' + +:meth:`~nameparser.Lexicon.add` and :meth:`~nameparser.Lexicon.remove` +both return a new :class:`~nameparser.Lexicon` — the one you started +from (here, ``Lexicon.default()``) is never mutated. Every field +accepts a plain set of lowercase words, keyword by field name (``titles`` +above; ``particles``, ``suffix_words``, and the rest work the same +way) — see :doc:`modules` for the full field list. + +``capitalization_exceptions`` is the one pair-valued field — each entry +maps a lowercase key to its exact-cased replacement (``"phd"`` → +``"PhD"``), so it isn't a fit for ``add()``/``remove()``. Change it with +``dataclasses.replace()`` instead: ``dataclasses.replace(lex, +capitalization_exceptions=(("phd", "PhD"),))``. + +Two fields — ``suffix_acronyms_ambiguous`` and ``particles_ambiguous`` +— mark entries from ``suffix_acronyms`` and ``particles`` that are also +plausible as ordinary name words on their own (an acronym suffix that +doubles as a nickname, a particle that doubles as a given name). They +don't add new vocabulary by themselves; they narrow how an existing +entry is read when it appears alone. If you're not sure whether a word +you're adding is one of these ambiguous cases, leave it out — an +unrecognized word usually still parses reasonably, while a wrongly +disambiguated one silently picks the less likely reading. (That +conservatism is why ``dean`` above isn't in the default vocabulary in +the first place: "Dean" is also a common given name, and a default +that swallowed it as a title would misparse "Dean Martin" for +everyone.) + +Behavior: Policy +----------------- + +When your data source or application needs different parsing behavior +— a different name order, stricter suffix rules, extra delimiters — +set it on :class:`~nameparser.Policy`, a small, closed set of fields, +listed below. + +.. list-table:: + :header-rows: 1 + :widths: 22 28 50 + + * - Field + - Type + - Effect + * - ``name_order`` + - one of the three exported order constants + - Assigns positional (no-comma) input to given/middle/family in + this order. Use the exported ``GIVEN_FIRST`` (default), + ``FAMILY_FIRST``, or ``FAMILY_FIRST_GIVEN_LAST`` constants. + Ignored when a comma separates family from given ("Thomas, + John" puts the family name first); a comma that only sets off + suffixes ("John Smith, Jr.") leaves it governing the name part. + * - ``patronymic_rules`` + - ``frozenset[PatronymicRule]`` + - Reorders patronymic-shaped names via opt-in detectors — East + Slavic formal order (``EAST_SLAVIC``) or Turkic reversed order + (``TURKIC``). Defaults to empty. + * - ``middle_as_family`` + - ``bool`` + - Folds ``middle`` into ``family`` instead of splitting them — + for naming systems with no middle-name concept. Defaults to + ``False``. + * - ``nickname_delimiters`` + - ``frozenset[tuple[str, str]]`` + - Routes content enclosed by these delimiter pairs to + ``nickname``. Defaults to + :data:`~nameparser.DEFAULT_NICKNAME_DELIMITERS` — straight + quotes and parentheses plus the typographic conventions (smart + quotes, guillemets, CJK brackets, ...). + * - ``maiden_delimiters`` + - ``frozenset[tuple[str, str]]`` + - Routes content enclosed by these delimiter pairs to ``maiden`` + instead, and drops them from the effective nickname set. + Defaults to empty — see the routing example below. + * - ``extra_suffix_delimiters`` + - ``frozenset[str]`` + - Adds separators that split suffix groups, e.g. ``" - "`` for + ``"Jane Smith, RN - CRNA"``. Additions only — the comma always + splits suffix groups and cannot be replaced. + * - ``lenient_comma_suffixes`` + - ``bool`` + - Reads an initial-shaped suffix word after a comma as a suffix: + ``"John Smith, V"`` is John Smith the fifth when ``True`` + (default); ``False`` reads ``V`` as a given-name initial + instead. Multi-letter suffixes (``III``, ``MD``) are + unaffected. + * - ``strip_emoji`` + - ``bool`` + - Excludes emoji from tokenization — they appear in no field or + rendered view, though ``original`` keeps them. Defaults to + ``True``. + * - ``strip_bidi`` + - ``bool`` + - Excludes bidirectional control characters the same way. + Defaults to ``True``. .. doctest:: - >>> import re - >>> from nameparser import HumanName - >>> from nameparser.config import Constants - >>> hn = HumanName("Benjamin {Ben} Franklin", constants=Constants()) - >>> hn.nickname - '' - >>> hn.C.nickname_delimiters['curly_braces'] = re.compile(r'\{(.*?)\}', re.U) - >>> hn.parse_full_name() - >>> hn.nickname - 'Ben' - -Routing to Maiden Name -~~~~~~~~~~~~~~~~~~~~~~~ - -Parenthesized (or otherwise delimited) alternate/maiden surnames -- -``"Baker (Johnson), Jenny"`` -- go to ``nickname`` by default, same as any -other delimited content.

Defaults to ``None`` (disabled). -* :py:obj:`~nameparser.config.Constants.initials_separator` - string placed between consecutive initials within the same name group (after the delimiter). Defaults to ``" "``, so ``"A. K."``; set to ``""`` for compact ``"A.K."``. -* :py:obj:`~nameparser.config.Constants.patronymic_name_order` - If set, detects Russian formal-order names (``Surname GivenName Patronymic``) via a trailing East-Slavic patronymic suffix and rotates the parts to Western order (``first=GivenName``, ``middle=Patronymic``, ``last=Surname``). Also detects reversed-order Azerbaijani/Central-Asian Turkic patronymics (``Surname GivenName PatronymicRoot Marker``, e.g. ``oglu``/``qizi``). Opt-in; see subsections below. -* :py:obj:`~nameparser.config.Constants.middle_name_as_last` - If set, folds middle names into the last name (``.last`` becomes what ``.surnames`` already was, ``.middle`` becomes empty). Opt-in; see subsection below. - - -Russian Formal Name Order -~~~~~~~~~~~~~~~~~~~~~~~~~ - -By default the parser treats all three-part names as ``First Middle Last``. For -Russian data in formal order (``Surname GivenName Patronymic``), enable -``patronymic_name_order``:: - - >>> from nameparser import HumanName - >>> from nameparser.config import Constants - >>> C = Constants(patronymic_name_order=True) - >>> hn = HumanName("Ivanov Ivan Ivanovich", constants=C) - >>> hn.first, hn.middle, hn.last - ('Ivan', 'Ivanovich', 'Ivanov') - -Detection is anchored on a recognised East-Slavic patronymic suffix -(``-ovich``, ``-ovna``, ``-evich``, ``-evna``, ``-ichna``, and the irregular -forms ``-ilyich``, ``-kuzmich``, ``-lukich``, ``-fomich``, ``-fokich``; same -patterns in Cyrillic). A comma activates the parser's standard -Last, First Middle path, which already handles Russian formal order — -reordering is suppressed to avoid a double-transformation. - -**Opt-in tradeoff:** when the flag is on, any name whose last token happens to -end in a patronymic suffix is reordered — including Western names with -patronymic-form surnames such as ``"David Michael Abramovich"``. Enable this -flag only when your data is predominantly Russian formal-order names. - - -Turkic Patronymics -~~~~~~~~~~~~~~~~~~ - -Azerbaijani and Central-Asian formal names follow a different shape: a -4-word ``[Given] [Father's given name] [Marker] [Family]``, where the -marker is a standalone word (``oglu``/``oğlu`` "son of", -``qizi``/``qızı`` "daughter of", and further variants — see below), not a -bound suffix. The same ``patronymic_name_order`` flag also detects and -rotates the reversed, no-comma form of this shape:: - - >>> from nameparser import HumanName - >>> from nameparser.config import Constants - >>> C = Constants(patronymic_name_order=True) - >>> hn = HumanName("Aliyev Vusal Said oglu", constants=C) - >>> hn.first, hn.middle, hn.last - ('Vusal', 'Said oglu', 'Aliyev') - -Natural order (``"Vusal Said oglu Aliyev"``) and comma order -(``"Aliyev, Vusal Said oglu"``) already parse correctly without this flag -and are left unchanged. - -Detection is scoped strictly to the 4-token shape (single-token first/last, -exactly two middle tokens, last token a recognised marker) — matching the -East-Slavic guard's token-count strictness above. Unlike that guard, there's -no additional check on the given-name token, since Turkic markers are a -small, closed set unlikely to coincide with an ordinary given name (whereas -East-Slavic patronymic suffixes can coincide with real Western surnames). -Recognised markers cover common transliterations and native orthographies: -Latin ``oglu``, ``oğlu``, ``ogly``, ``ogli``, ``o'g'li`` (and its Uzbek -modifier-apostrophe and right-single-quote variants), ``qizi``, ``qızı``, -``kizi``, ``kyzy``, ``gyzy``, ``uly``, ``uulu``; and Cyrillic ``оглу``, -``оглы``, ``оғлу``, ``ўғли``, ``угли``, ``кызы``, ``гызы``, ``қызы``, -``қизи``, ``улы``, ``ұлы``, ``уулу``. Matching is case-insensitive. - - -Suppressing Middle Names -~~~~~~~~~~~~~~~~~~~~~~~~~ - -Some naming systems have no middle-name concept — everything after the given -name is lineage or family (e.g. Arabic patronymic chaining: given + father + -grandfather + family). Enable ``middle_name_as_last`` to fold the middle name -into the last name instead of splitting them:: - - >>> from nameparser import HumanName - >>> from nameparser.config import Constants - >>> C = Constants(middle_name_as_last=True) - >>> hn = HumanName("Mohamad Ahmad Ali Hassan", constants=C) - >>> hn.first, hn.middle, hn.last - ('Mohamad', '', 'Ahmad Ali Hassan') - -The fold applies uniformly to comma input too, so both written forms of a name -converge on the same result:: - - >>> hn2 = HumanName("Hassan, Mohamad Ahmad Ali", constants=C) - >>> hn2.first, hn2.last - ('Mohamad', 'Ahmad Ali Hassan') - - -Splitting last-name prefix particles -------------------------------------- - -The :py:attr:`~nameparser.parser.HumanName.last_base` and -:py:attr:`~nameparser.parser.HumanName.last_prefixes` properties split the last -name at the boundary between leading prefix particles and the core surname. They -use the same ``PREFIXES`` set, so adding a particle makes the split pick it up -automatically:: - - >>> from nameparser import HumanName - >>> from nameparser.config import CONSTANTS - >>> CONSTANTS.prefixes.add('op') # doctest: +ELLIPSIS - SetManager({...}) - >>> HumanName("Jan op den Berg").last_base - 'Berg' - >>> HumanName("Jan op den Berg").last_prefixes - 'op den' - >>> CONSTANTS.prefixes.remove('op') # doctest: +ELLIPSIS - SetManager({...}) - -Note the ``remove`` call at the end — ``customize.rst`` examples share global -``CONSTANTS``, so mutations must be reversed to avoid affecting later examples. - -Because ``last_base`` is a plain string property, sorting a list of names by -core surname (ignoring prefix particles like *van*, *de la*) is just a key -function:: - - names = [ - HumanName("Vincent van Gogh"), - HumanName("Juan de la Vega"), - HumanName("John Smith"), - ] - sorted_names = sorted(names, key=lambda n: n.last_base.lower()) - # sort keys: 'gogh', 'smith', 'vega' → van Gogh, Smith, de la Vega - -To sort by first name when two people share the same ``last_base``, add it as -a secondary key:: - - sorted_names = sorted(names, key=lambda n: (n.last_base.lower(), n.first.lower())) - -Bound First Names ------------------- - -``CONSTANTS.bound_first_names`` controls bound given-name prefixes that attach -to the following word to form one first name.

A +:class:`~nameparser.PolicyPatch` is a :class:`~nameparser.Policy`-shaped +patch: every field defaults to :data:`~nameparser.UNSET` (leave it +alone) instead of to a concrete value, so a pack only ever states what +it changes. + +.. doctest:: + + >>> from nameparser import Lexicon, Locale, PolicyPatch, parser_for + >>> lex = Lexicon.empty().add(titles={"kapitan"}) + >>> mine = Locale(code="mycorp", lexicon=lex, + ... policy=PolicyPatch(middle_as_family=True)) + >>> name = parser_for(mine).parse("Kapitan Anna Maria Schmidt") + >>> name.title, name.given, name.family + ('Kapitan', 'Anna', 'Maria Schmidt') + +That pack does two things at once: the :class:`~nameparser.Lexicon` +fragment teaches the parser that ``kapitan`` is a title, and the +:class:`~nameparser.PolicyPatch` turns on ``middle_as_family`` so any +remaining given-position words after the first fold into ``family`` +instead of ``middle`` — compare this to the default parser's reading +of the same string, which has no title and splits ``given='Kapitan'``, +``middle='Anna Maria'``, ``family='Schmidt'``. + +When ``parser_for`` folds one or more packs onto a base, lexicons +union (a pack's words are added to the base's, never removed); policy +fields declared as set-valued in :class:`~nameparser.PolicyPatch` +(``patronymic_rules`` and the delimiter fields) union the same way; +and every other, scalar field is later-wins — if two packs (or a pack +and an explicit conflicting value) set the same scalar field, the last +one applied wins and a ``UserWarning`` is raised so the conflict +isn't silent. + +Contributing a pack to nameparser +---------------------------------- + +Shipping a pack in nameparser itself (rather than keeping it local to +your own code) means meeting the in-repo contract, checked mechanically +by ``tests/v2/test_locales.py``: + +#. Add a registry entry in ``nameparser/locales/__init__.py`` — a + ``"CODE": ("module.path", "ATTR")`` row in ``_REGISTRY``, so the + pack loads lazily on first access (importing ``nameparser.locales`` + never imports pack modules). +#. Declare a module-level ``DEVIATES(name)`` predicate: given a name + string, return whether *this pack alone* might parse it differently + from the default parser. Over-declaring is safe; under-declaring is + not — when in doubt, ``DEVIATES`` should say yes. +#. Add a rotator list to ``tests/v2/test_locales.py`` with at least one + name exercising every alternation branch of every marker regex the + pack defines — ``test_rotators_cover_every_marker_branch`` fails + until each branch is hit. +#. Keep the non-interference gate green over the shared corpus plus + your rotators: every name the packed parser parses differently from + the default must be one your ``DEVIATES`` predicate flags — no + silent, undeclared side effects on names outside the pack's stated + scope. +#.

Side effect: parenthesized/quoted ``"(MA)"``/``"(DO)"`` (no periods) no longer escape to ``suffix`` the way 1.x did -- they now fall through to nickname parsing like any other ambiguous-acronym delimited content. Not present in the differential corpus + - Change suffix-delimiter rendering: with a custom ``Policy``/``Constants`` suffix delimiter configured (e.g. ``suffix_delimiter="/"``, ``"John Smith, RN/CRNA"``), 1.x split the token and rendered ``suffix="RN, CRNA"``; 2.0 keeps the no-space delimiter-core token whole (``suffix="RN/CRNA"``) -- role assignment is unchanged, only rendering differs (anti-#100, migration plan deviation 5; ``tests/v2/cases.py`` row ``suffix_delimiter_no_space_core``). Only fires with a non-default policy, so it does not appear in the (default-policy) differential corpus + - Change ``comparison_key()``/``matches()`` (both APIs) to fold components with ``str.casefold()`` where 1.4 used ``str.lower()``: Unicode case-pair forms now compare equal -- ``"STRASSE"`` matches ``"Straße"``, and a Greek final-sigma variant matches its regular-sigma form. Strictly more permissive (anything 1.4 matched still matches); parse output is unaffected -- vocabulary normalization itself uses ``lower()``, v1-parity (``tests/v2/test_types.py`` row ``test_matches_casefolds_unicode_case_pairs``) + - Change delimiter-overlap precedence in the 2.0 API: a pair listed in ``Policy.maiden_delimiters`` is dropped from the effective ``nickname_delimiters`` set (maiden wins), so ``Policy(maiden_delimiters={("(", ")")})`` alone routes parenthesized content to ``maiden`` -- no need to rebuild the nickname set. The default nickname set is now the public ``DEFAULT_NICKNAME_DELIMITERS`` constant. The 1.x facade keeps v1's nickname-wins precedence on overlap via a shim-side pre-subtraction, so no ``HumanName`` behavior changes (``tests/v2/cases.py`` row ``maiden_delimiters_win_when_shared``; ``tests/v2/test_config_shim.py`` row ``test_snapshot_overlap_keeps_v1_nickname_precedence``) + - Recognize typographic nickname delimiters by default in BOTH APIs (closes #273): smart quotes (``“Jack”``), German/Polish low-high quotes (``„Hansi“``), Swedish right-right quotes (``”Ann”``), guillemets in both directions (``«Petit»``, ``»Hansi«``, inner spacing tolerated), CJK corner brackets (``「タロ」``/``『ハナ』``), and fullwidth parentheses. In 1.x these leaked into ``middle`` as literal text. Curly *single* quotes stay excluded (U+2019 is the apostrophe in "O’Connor" -- pinned by ``curly_apostrophe_stays_literal``). The v1 keyed idioms work on the new named sentinels (``smart_double_quotes``, ``guillemets``, ...).
