JavaScript

The JavaScript code passes each raw number for cardinality selection and formats its display value separately with Intl.NumberFormat.

import { cardinalityForNumber, createStrings } from "lokalized";
import { readStringsFromDirectory } from "lokalized/node";

const locale = "br";

const strings = createStrings({
  localizedStringSupplier: () => readStringsFromDirectory("strings").catalogs,
  fallbackLocale: locale,
  localeSupplier: () => locale,
});

const numberFormat = new Intl.NumberFormat(locale);

// Raw numbers select language forms; Intl.NumberFormat produces the display values

// CARDINALITY_ONE
const oneCardinality = 1;
const oneFormattedCardinalityValue = numberFormat.format(oneCardinality);

cardinalityForNumber(oneCardinality, locale).name;   // => "CARDINALITY_ONE"
strings.get("Cardinality.MinimalPair", {
  cardinalityValue: oneCardinality,
  formattedCardinalityValue: oneFormattedCardinalityValue,
});   // => "1 cʼhi"

// CARDINALITY_TWO
const twoCardinality = 2;
const twoFormattedCardinalityValue = numberFormat.format(twoCardinality);

cardinalityForNumber(twoCardinality, locale).name;   // => "CARDINALITY_TWO"
strings.get("Cardinality.MinimalPair", {
  cardinalityValue: twoCardinality,
  formattedCardinalityValue: twoFormattedCardinalityValue,
});   // => "2 gi"

// CARDINALITY_FEW
const fewCardinality = 3;
const fewFormattedCardinalityValue = numberFormat.format(fewCardinality);

cardinalityForNumber(fewCardinality, locale).name;   // => "CARDINALITY_FEW"
strings.get("Cardinality.MinimalPair", {
  cardinalityValue: fewCardinality,
  formattedCardinalityValue: fewFormattedCardinalityValue,
});   // => "3 cʼhi-error"

// CARDINALITY_MANY
const manyCardinality = 1_000_000;
const manyFormattedCardinalityValue = numberFormat.format(manyCardinality);

cardinalityForNumber(manyCardinality, locale).name;   // => "CARDINALITY_MANY"
// U+00A0 NO-BREAK SPACE preserves exact nonbreaking spacing from localized source text or locale formatting
strings.get("Cardinality.MinimalPair", {
  cardinalityValue: manyCardinality,
  formattedCardinalityValue: manyFormattedCardinalityValue,
});   // => "1\u00A0000\u00A0000 a chas"

// CARDINALITY_OTHER
const otherCardinality = 0;
const otherFormattedCardinalityValue = numberFormat.format(otherCardinality);

cardinalityForNumber(otherCardinality, locale).name;   // => "CARDINALITY_OTHER"
strings.get("Cardinality.MinimalPair", {
  cardinalityValue: otherCardinality,

Swift

Swift uses pinned CLDR rules for raw numeric values. The display strings in these assertions are fixed examples; applications format display values separately with Foundation. Default .rtlLocales bidi isolation adds FSI/PDI to interpolated values in right-to-left output.

import Foundation
import Lokalized

let locale = try LocaleTag("br")
let files = try LocalizedStringLoader.loadFromDirectory(URL(fileURLWithPath: "strings"))
let catalogs = files.mapValues { LocalizedCatalog(strings: $0.strings) }

let strings = try DefaultStrings(configuration: StringsConfiguration(
  localizedStringSupplier: { catalogs }, localeSupplier: { _ in locale },
  fallbackLocale: locale
))

// CARDINALITY_ONE
let number1 = try NumericValue.forDecimal("1")
let category1 = try Cardinality.forNumber(number1, locale: locale.tag)
assert(category1 == .one)
// This fixed display value makes the translation assertion reproducible.
let display1 = "1"
let message1 = try strings.get("Cardinality.MinimalPair", placeholders: [
  "cardinalityValue": .number(number1),
  "formattedCardinalityValue": .text(display1),
])
assert(ExactString(message1) == ExactString("1 cʼhi"))

// CARDINALITY_TWO
let number2 = try NumericValue.forDecimal("2")
let category2 = try Cardinality.forNumber(number2, locale: locale.tag)
assert(category2 == .two)
// This fixed display value makes the translation assertion reproducible.
let display2 = "2"
let message2 = try strings.get("Cardinality.MinimalPair", placeholders: [
  "cardinalityValue": .number(number2),
  "formattedCardinalityValue": .text(display2),
])
assert(ExactString(message2) == ExactString("2 gi"))

// CARDINALITY_FEW
let number3 = try NumericValue.forDecimal("3")
let category3 = try Cardinality.forNumber(number3, locale: locale.tag)
assert(category3 == .few)
// This fixed display value makes the translation assertion reproducible.
let display3 = "3"
let message3 = try strings.get("Cardinality.MinimalPair", placeholders: [
  "cardinalityValue": .number(number3),
  "formattedCardinalityValue": .text(display3),
])
assert(ExactString(message3) == ExactString("3 cʼhi-error"))

// CARDINALITY_MANY
let number4 = try NumericValue.forDecimal("1000000")
let category4 = try Cardinality.forNumber(number4, locale: locale.tag)
assert(category4 == .many)
// This fixed display value makes the translation assertion reproducible.
let display4 = "1\u{A0}000\u{A0}000"
let message4 = try strings.get("Cardinality.MinimalPair", placeholders: [

let category5 = try Cardinality.forNumber(number5, locale: locale.tag)
assert(category5 == .other)
// This fixed display value makes the translation assertion reproducible.
let display5 = "0"

JavaScript

The JavaScript code passes raw range endpoints for selection, formats both endpoints separately with Intl.NumberFormat, and joins them for display; choose range punctuation appropriate to your application. Range rules are an optional import, lokalized/data/ranges.

import { cardinalityForNumber, createStrings, decimal } from "lokalized";
import { cardinalRangeData, cardinalityForRange } from "lokalized/data/ranges";
import { readStringsFromDirectory } from "lokalized/node";

const locale = "br";

const strings = createStrings({
  localizedStringSupplier: () => readStringsFromDirectory("strings").catalogs,
  fallbackLocale: locale,
  localeSupplier: () => locale,
  pluralData: { ranges: cardinalRangeData },
});

const numberFormat = new Intl.NumberFormat(locale);

// Raw numbers select language forms; Intl.NumberFormat produces the display values

// CARDINALITY_OTHER range (ending-cardinality fallback)
const minDays = 0;
const formattedMinDays = numberFormat.format(minDays);
const maxDays = decimal("0.9");
const formattedMaxDays = new Intl.NumberFormat(locale, { minimumFractionDigits: 1, maximumFractionDigits: 1 })
  .format("0.9");
const formattedDayRange = formattedMinDays + "-" + formattedMaxDays;

cardinalityForRange(
  cardinalityForNumber(minDays, locale),
  cardinalityForNumber(maxDays, locale),
  locale
).name;   // => "CARDINALITY_OTHER"
strings.get("Delivery.Window", { minDays, maxDays, formattedDayRange });   // => "0-0,9 deiz"

Java

The Java code passes raw range endpoints for selection. Because NumberFormat formats one number at a time, it formats both endpoints separately and joins them for display; choose range punctuation appropriate to your application.

  .localizedStringSupplier(() -> LocalizedStringLoader.loadFromFilesystem(Paths.get("strings")))

// Raw numbers select language forms; NumberFormat produces the display values

// CARDINALITY_OTHER range (ending-cardinality fallback)
Number minDays = 0;
String formattedMinDays = numberFormat.format(minDays);
Number maxDays = new java.math.BigDecimal("0.9");
NumberFormat maxDaysFormat = NumberFormat.getNumberInstance(locale);
maxDaysFormat.setMinimumFractionDigits(1);
maxDaysFormat.setMaximumFractionDigits(1);
String formattedMaxDays = maxDaysFormat.format(maxDays);
String formattedDayRange = formattedMinDays + "-" + formattedMaxDays;

assertEquals(Cardinality.OTHER, Cardinality.forRange(
  Cardinality.forNumber(minDays, locale),
  Cardinality.forNumber(maxDays, locale),
  locale

// Expected: 0-0,9 deiz
