What does this PR do?

Part 3 of 7 of the 2.4.0 release stack (main <- stack/01-tooling <- ... <- stack/07-docs). Every fix(<scope>) commit: corrects behavior of functions that already exist, adds no new function. Each commit body states the previous behavior, the new behavior and the source it was checked against. Twelve of these change an output for inputs that were previously accepted or rejected; they are listed in the CHANGELOG entry that lands in PR 7 and were each compared against the published 2.3.0 tarball.

Commits in this part (13)

  • 81f397f fix(currency): parse real decimal/thousands separators and never format non-finite values
  • f489f53 fix(ie): accept SP produtor rural and Tocantins 11-digit registrations
  • 6852e86 fix(cep): reject non-digit characters and drop the dead widenet provider
  • bf7a4d0 fix(states): sort by pt-BR locale and return fresh, mutation-safe copies
  • 9d4ac02 fix(cities): return fresh copies and cache the combined list
  • 78ffccc fix(license-plate): strip mask characters and add Mercosul conversion
  • 7ed931e fix(processo-juridico): use the CNJ Resolução 65/2008 dot-separated mask
  • 40bd8a9 fix(capitalize): match user word lists case-insensitively and treat - and / as word boundaries
  • 630beaf fix(passport): accept lowercase and mask characters
  • 414efb7 fix(pis): accept alphanumeric-style separators and avoid repeated-digit bases
  • 3a6d005 fix(legal-nature): replace the table with IBGE/CONCLA Natureza Jurídica 2021
  • c719d10 fix(holidays): audit every state holiday against its law
  • dab3ddb fix(holidays): isHoliday returns a boolean and never throws

📝 Walkthrough

Walkthrough

The pull request adds typed IBGE and CONCLA data generation, decimal and currency parsing, holiday resolution, state IE validation, license-plate conversion, locale-aware text handling, defensive-copy behavior, and expanded tests across Brazilian utility modules.

Changes

Reference data and shared constants

Layer / File(s) Summary
Generated reference data
scripts/cities.ts, scripts/legal-natures.ts, scripts/states.ts, src/_internals/constants/*, src/is-valid-legal-nature/constants.ts
City data now includes codes and typed state mappings. State data now includes IBGE codes. Legal-nature data is generated from the 2021 CONCLA table and retains legacy codes.
Decimal and currency behavior
src/_internals/clamp-precision/*, src/_internals/parse-decimal/*, src/parse-currency/*, src/format-currency/*
New decimal parsing and precision-clamping utilities support Brazilian separators, signs, minor units, precision limits, and cached currency formatters.

Formatters, generators, and validators

Layer / File(s) Summary
Text and license plates
src/capitalize/*, src/get-format-license-plate/*, src/is-valid-license-plate/*, src/generate-license-plate/*, src/convert-license-plate-to-mercosul/*
Capitalization handles whitespace, hyphens, slashes, and locale rules. License-plate handling removes the withdrawn motorcycle sequence and adds old-format to Mercosul conversion.
Formatters and generators
src/format-*, src/generate-*, src/parse-*, src/is-valid-cep/*, src/is-valid-passport/*, src/is-valid-pis/*, src/is-valid-processo-juridico/*
Formatters and generators use shared constants, explicit invalid-input handling, corrected legal masks, and updated documentation.
State IE validation
src/is-valid-ie/*
State-specific validators now share check-digit helpers and constants. Goiás, São Paulo, Tocantins, prefix handling, and state-code validation receive targeted updates.

Lookups and calendars

Layer / File(s) Summary
Address and location lookups
src/get-address-info-by-cep/*, src/get-cep-info-by-address/*, src/get-cities/*, src/get-states/*
CEP providers now have updated defaults and error classification. Address normalization, city sorting, state validation, caching, and defensive copies are updated.
Holiday calendar
src/get-holidays/*, src/is-holiday/*
Holidays now include types, state-law date ranges, Easter offsets, national Consciência Negra handling, corrected Corpus Christi calculation, memoization, and defensive copies.

Priority: ➖ Normal

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to ed1ef

This change is not ready to merge because package loading can fail and several utilities can return invalid or misleading results for supported inputs. The import failure and remaining validation, holiday, address, and generator issues should be corrected first.

In `@src/convert-license-plate-to-mercosul/convert-license-plate-to-mercosul.ts`:
- Line 30: Validate the original input with getFormatLicensePlate(value) before
calling parseLicensePlate, so overlong values such as ABC1234EXTRA are rejected
rather than accepted after truncation. Preserve conversion only for valid
old-format input, and add a regression test covering the overlong case.

In `@src/get-cep-info-by-address/get-cep-info-by-address.ts`:
- Around line 52-55: Align the validation and documentation for the city and
street fields in the get-cep-info-by-address input type and its validation flow:
enforce a minimum of three characters so short values produce
GetCepInfoByAddressValidationError, or remove the three-character claim from the
JSDoc if the existing empty-string validation and public error message must
remain unchanged.
- Line 3: Resolve the missing dependency used by getCepInfoByAddress by either
adding the removeAccents implementation or updating its import to the
repository’s existing equivalent. Ensure the import in getCepInfoByAddress
resolves successfully when src/index.ts loads.

In `@src/get-holidays/constants.ts`:
- Line 139: Remove the Nossa Senhora do Rocio entry from FIXED_HOLIDAYS, along
with its associated `@see` reference and corresponding test coverage; retain the
existing Proclamação da República holiday for 15 November.
- Line 155: Remove the “Dia do Rio Grande do Norte” entry from STATE_HOLIDAYS.RN
and delete its associated `@see` reference; update the RN holiday test to assert
that 7 August is absent while preserving all other RN holidays.

In `@src/is-valid-cep/is-valid-cep.ts`:
- Line 29: Update the validation flow around CEP_REGEX and SEPARATORS_REGEX to
reject numeric inputs that are negative or non-integer before converting them to
strings and removing separators; preserve existing mask normalization and
validation for acceptable numeric and string values.

In `@src/is-valid-ie/is-valid-ie.ts`:
- Line 621: Update the validator lookup using IE_VALIDATORS so inherited names
such as constructor, toString, __proto__, and valueOf are rejected before
reading the entry; require the key to be an own property and return false for
non-own names while preserving normal validation for registered validators.

In `@src/parse-currency/parse-currency.ts`:
- Line 5: Update the precision option documentation near parseCurrency to state
that it controls minor-unit scaling and only increases the accepted fractional
length beyond the default two digits; clarify that precision values of 0 or 1
still accept up to two fractional digits.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Align the documented minimum length with the validation.

Lines 52 and 55 state that city and street need at least 3 characters. The validation only rejects empty strings. A 2-character city therefore reaches ViaCEP and rejects with GetCepInfoByAddressError, not the documented GetCepInfoByAddressValidationError. Enforce the minimum length, or remove the claim from the documentation.

🛠️ Proposed fix that enforces the documented minimum
-	if (!city || !street) {
-		throw new GetCepInfoByAddressValidationError("City and street are required");
+	if (normalizeAddressPart(city).length < 3 || normalizeAddressPart(street).length < 3) {
+		throw new GetCepInfoByAddressValidationError(
+			"City and street are required and must have at least 3 characters",
+		);
 	}

The existing message text is part of the public contract. If it must stay unchanged, keep the current check and drop the 3-character wording from the JSDoc instead.

Lei 22.360/2025 Paraná Nossa Senhora do Rocio 15 de novembro feriado estadual texto da lei

💡 Result:

A Lei Estadual n.º 22.360, sancionada em 15 de abril de 2025, reconhece oficialmente Nossa Senhora do Rocio como Padroeira do Estado do Paraná e insere o Dia da Padroeira do Paraná no Calendário Oficial de Eventos do Estado, a ser comemorado anualmente em 15 de novembro [1][2][3][4]. É importante notar que a referida lei tem por objetivo homenagear a devoção popular e oficializar a data no calendário estadual de eventos [4][5]. O texto da lei não estabelece o dia 15 de novembro como feriado estadual [1][5]. A data de 15 de novembro já é feriado nacional, dedicado à Proclamação da República, o que coincide com a celebração da padroeira [5]. Em resumo, a Lei n.º 22.360/2025 confere reconhecimento oficial à santa como padroeira e cria uma data comemorativa estadual, mas não altera o regime jurídico da data de 15 de novembro para fins de feriado estadual [1][3][5].

site:assembleia.pr.leg.br Lei Estadual 22.360 2025 Nossa Senhora do Rocio texto integral 15 novembro feriado calendário oficial

💡 Result:

A Lei Estadual nº 22.360, sancionada em 2025, reconhece oficialmente Nossa Senhora do Rocio como Padroeira do Estado do Paraná e inclui o Dia da Padroeira do Paraná, celebrado anualmente em 15 de novembro, no Calendário Oficial de Eventos do Estado [1]. O texto legal, que teve origem no Projeto de Lei nº 896/2023, estabelece formalmente o reconhecimento da padroeira no âmbito civil e estadual, além de oficializar a data comemorativa no calendário do Paraná [1][2][3]. É importante destacar que a inclusão de uma data no "Calendário Oficial de Eventos do Estado" tem como finalidade a promoção e o reconhecimento cultural e histórico, não constituindo automaticamente um feriado estadual (que exige legislação específica para tal definição) [1][2]. A legislação foi de autoria dos deputados Anibelli Neto (MDB) e Evandro Araújo (PSD) [1][2].

Lei Paraná 18.297 2014 Dia de Nossa Senhora do Rocio feriado estadual texto

💡 Result:

A Lei Estadual nº 18.297 do Paraná, de 2014, não trata sobre o Dia de Nossa Senhora do Rocio. Pesquisas em repositórios legislativos indicam que a Lei Estadual nº 18.297/2014 refere-se a matéria distinta e não possui relação com feriados ou datas comemorativas religiosas [1][2][3]. A inclusão de Nossa Senhora do Rocio no calendário oficial do estado e seu reconhecimento civil como Padroeira do Paraná ocorreram por meio de uma legislação mais recente, a Lei Estadual nº 22.360, sancionada em 2025 [4][5][6]. Esta norma reconhece oficialmente Nossa Senhora do Rocio como Padroeira do Estado do Paraná e estabelece a celebração de seu dia em 15 de novembro no Calendário Oficial de Eventos do Estado [4][6]. Embora a data de 15 de novembro seja celebrada intensamente no estado, especialmente em Paranaguá, onde se localiza o seu Santuário Estadual, o reconhecimento oficial da data como feriado estadual tem sido objeto de discussão legislativa [6][7]. A legislação citada (Lei nº 22.360/2025) focou no reconhecimento da padroeira e na inclusão da data no calendário oficial de eventos [4][6].

Remove the Nossa Senhora do Rocio state-holiday entry

Lei PR nº 18.297/2014 does not establish this holiday. Lei PR nº 22.360/2025 recognizes Nossa Senhora do Rocio and adds 15 November to the official events calendar, but it does not create a state holiday. Since FIXED_HOLIDAYS already includes Proclamação da República on 15 November and state entries are appended without deduplication, remove the PR entry, its @see reference, and the corresponding test.

Reject signed and fractional numeric CEP values.

Line 29 applies string mask normalization to numeric values. As a result, isValidCep(-20040020) and isValidCep(123456.78) both return true. Reject negative or non-integer numbers before removing separators.

Validate the IBGE response before generation.

If the successful payload is not an array, json.sort throws. If a state lacks regiao, the mapping at line 38 throws. The State[] annotation does not validate response.json() at runtime. Parse the payload as unknown and validate the array and required fields before writing states.ts. Add fixtures for both invalid shapes.

…at non-finite values

parseCurrency now reads the last "," or "." followed by up to precision digits as the
decimal separator and every other one as a thousands separator, via the new shared
parseDecimal internal, instead of always dividing by 100 as if the input were cents.
parseCurrency preserves a leading "-" instead of dropping the sign.
formatCurrency(NaN) / formatCurrency(Infinity) -> "" instead of "NaN"/"∞".
Both clamp precision to 0-100 (the range Intl.NumberFormat accepts) via the new
clampPrecision internal, and parseCurrency gains a { precision } option.
perf: cache Intl.NumberFormat instances per (symbol, precision) pair.
Goiás prefixes are 10/11/15 (were 10/11/12/20); Pará accepts 15 and 75-79;
Mato Grosso do Sul accepts 28/50.
Support São Paulo produtor rural (P0MMMSSSSD000) and Tocantins 11-digit codes;
the UF is now case-insensitive.
isValidCep only counted digits, so letters mixed with 8 digits passed; it now
matches a plain digit regex after stripping the usual separators and accepts
number input.
Remove the widenet provider from getAddressInfoByCep'"'"'s default list (dead endpoint,
HTTP 502); it stayed usable when requested explicitly.
getCepInfoByAddress lets the underlying fetch failure propagate instead of wrapping it.
getStates() used code-unit order ("Pará" after "Paraná"); it now sorts with
localeCompare in the "pt-BR" locale.
getStates() returned the shared internal array, so mutating the result corrupted
data for every subsequent call; it now returns fresh objects on every call.
Add ibgeCode to each State entry (the 2-digit IBGE code of the Federative Unit).
getCities() returned the shared internal arrays, the same mutation hazard as
getStates(); it now returns fresh, mutation-safe arrays (Object.hasOwn replaces
the `in` check) and the all-cities list is computed once and cached.
scripts/cities.ts: fall back to the IBGE regiao-imediata field when microrregiao
is absent from the API response.
isValidLicensePlate("abc 1234") -> true; mask characters are stripped from any
position while extra characters are still rejected.
Export the LicensePlateFormat type (GenerateLicensePlateFormat is now an alias of it).
Add convertLicensePlateToMercosul: "LLLNNNN" -> "LLLNLNN" (5th digit -> letter
0->A..9->J), or null when the input is not an old-format plate.
The mask was missing the dot between the justiça and tribunal/região digits:
formatProcessoJuridico(...) -> "0002080-25.2012.5.15.0049" (was "...515.0049").
parseProcessoJuridico accepts both the old and the new mask as input.
generateProcessoJuridico({ year: 99999 }) -> null; year must be between the
current year and 9999 (was a 21-character string). Res. CNJ 65/2008.
… and / as word boundaries

upperCaseWords/lowerCaseWords are matched case-insensitively:
capitalize("empresa ltda", { upperCaseWords: ["ltda"] }) -> "Empresa LTDA".
The default word lists are unchanged ("empresa ltda" -> "Empresa Ltda").
Treat - and / as word boundaries: "MOGI-GUAÇU" -> "Mogi-Guaçu" (was "Mogi-guaçu").
Collapse runs of whitespace and case using the pt-BR locale.
isValidPassport("ab123456") -> true (was false); accept mask characters such
as "AB-123.456".
…it bases

isValidPis accepts whitespace and the common separators between groups.
generatePis retries when the generated base would be a repeated-digit sequence.
…ca 2021

Replace the outdated, unaccented 60-code table with the official 2021 table
(92 official codes + 8 legacy codes kept for compatibility, 100 total).
Descriptions now use the official accented wording.
Every STATE_HOLIDAYS entry now carries a @see citation to the law that created it,
extracted into a new get-holidays/constants.ts.
Added: AP Consciência Negra (2007-2023), PB 26/07, PR 15/11, TO 18/03, ES Nossa
Senhora da Penha (Easter+8).
Removed (no law found / not an actual holiday): CE 19/03, ES 23/05, GO 05/07 and
26/07, MT 09/05, MG 21/07, RJ 20/01.
Fixed: RN 07/09 -> 07/08 (was duplicating Independência do Brasil); the MT/RJ
entry is renamed to "Dia da Consciência Negra"; AL 16/09 is now marked optional.
Each Holiday carries a type ("national"|"state"|"optional"|"religious") and
results are memoized per year/stateCode, returning fresh copies on every call.
isHoliday(null) / isHoliday() threw a TypeError; it now returns false instead of
throwing or returning the matched Holiday, so it can'"'"'t be used to read holiday
details (use getHolidays for that).
The comparison uses the Date'"'"'s local calendar date.
