From d18b95880dbc46dbbb10b0bc783cef085710e31d Mon Sep 17 00:00:00 2001 From: Michael Date: Fri, 1 May 2026 03:06:03 +0000 Subject: [PATCH] feat(format-i18n): broaden international coverage across all domains MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes ~17 high-value international gaps surfaced by parallel review. Adds 93 regression tests; full project suite now 1323 / 0 / 17 (passed / failed / xfailed). DATES - Adds Portuguese, Italian, Dutch, Russian month dictionaries to the opt-in ``month_locales`` set (now: en, fr, de, es, pt, it, nl, ru). - Adds localized weekday recognition for those locales — "Lundi", "Montag", "lunedì", "понедельник", etc. all strip cleanly before format matching. - New CJK separator normalization: Japanese ``2024年01月15日`` and fullwidth digits ``2024/01/15`` fold to ASCII before parsing. - New named-timezone resolution: EST/PST/JST/CET/IST/GMT/etc. map to fixed UTC offsets via ``_NAMED_TZ_OFFSETS`` so the trailing TZ doesn't block format matching. - New ISO 8601 extended formats: week date (``2024-W03-1``) and ordinal date (``2024-015``), plus RFC 2822 mail-header form (``Mon, 15 Jan 2024 10:30:00``). - New ``two_digit_year_cutoff`` parameter on ``standardize_date()`` — defaults to Python's stdlib 69; lower it for birth-year columns where most subjects were born ≤ 1999. NAMES - Particles set extended with Arabic patronymic markers (bin, ibn, bint, abu, abd, al, al-, el-) and Hebrew (ben, bat, ha, ha-). - Title set extended with German (Herr, Frau), French (M., Mme, Mlle), Spanish (Sr., Sra., Srta., Don, Doña), Italian (Sig., Sig.ra, Dott.), Portuguese. - Acronym map extended with international academic credentials (Dipl, Ing, Mag, Habil, MSc, BSc, LLB, LLM). - New East Asian honorific suffix handler: ``Tanaka-san``, ``Lee-ssi``, ``Park-nim`` keep the suffix lowercase after the hyphen instead of being title-cased into ``Tanaka-San``. - Hyphenated-segment handler now keeps Arabic prefixes ``al-`` / ``el-`` lowercase per Arabic transliteration convention. - New ``family_first`` parameter on ``standardize_name()`` and matching ``name_family_first`` field on ``StandardizeOptions`` — set per-column for East Asian data to skip Western comma-format reversal (``Kim, Min-jae`` stays ``Kim, …`` instead of becoming ``Min-jae Kim``). CURRENCY - Symbol map extended: ฿(THB), ₫(VND), ₮(MNT), ₴(UAH), ₦(NGN), ₱(PHP), ₲(PYG), ﷼(SAR), ₨(PKR), ₵(GHS) — covers SE Asia, Africa, Eastern Europe, Latin America gaps. - ISO 4217 code list extended from 23 to ~50: SAR, AED, QAR, KWD, BHD, OMR, ARS, CLP, COP, EGP, IDR, MYR, PHP, THB, VND, NGN, GHS, KES, HUF, CZK, RON, UAH, KZT, etc. EMAIL - New BIDI / RTL override stripping (``standardize_email``): U+202A-U+202E and U+2066-U+2069 stripped from every email. These are a known phishing vector — ``alice‮@example.com`` displays as ``alice@elpmaxe.com`` to RTL-aware renderers. ADDRESS - Canadian provinces: 13 codes + names → 2-letter (Ontario → ON). - UK postcode pattern recognition (``SW1A 2AA`` shape). - Australian states: 8 codes + names (NSW, VIC, QLD, … + full names). - German Bundesland: 16 codes + names (Bayern → BY, etc.). - International PO Box variants: ``Postfach`` (DE), ``Boîte postale`` (FR), ``Apartado`` (ES), ``Casella postale`` (IT), ``Caixa postal`` (PT) — all fold to canonical ``PO Box``. - ``_INTL_STATE_CODES`` now combines US/CA/AU/DE codes; the position check that preserves state codes regardless of input case applies to all four jurisdictions. - ``_is_state_code_position`` postal pattern broadened to recognize US ZIP, AU 4-digit, CA first half, and UK outward code. CONSTANTS - ``src/core/_constants.py`` gains: ``CA_PROVINCE_CODES`` / ``CA_PROVINCE_NAMES``, ``AU_STATE_CODES`` / ``AU_STATE_NAMES``, ``DE_STATE_CODES`` / ``DE_STATE_NAMES``, ``POSTAL_PATTERNS`` (us/ca/uk/de/au/fr), ``INTL_PO_BOX_PATTERNS`` (per-language regex), ``INTL_STREET_SUFFIXES`` (de/fr/es/it/uk dictionaries — ready for use when address takes a `country_hint` parameter in a future pass). DOCS - TECHNICAL.md §11.3 domain table updated with the new handling per domain plus a new "International coverage" sub-section listing the supported locales / symbols / jurisdictions. DEFERRED (out of scope or rare) - Alternative calendars (Japanese era, Hijri, Hebrew, Buddhist) — corpus § 3.5 marks out of scope. - Persian/Arabic-Indic digit conversion — rare in tabular data. - Trailing-minus RTL currency convention. - Punycode ↔ Unicode IDN normalization. - Mixed-country phone column auto-detection (user can override ``default_region`` per column).
