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 = "zu";

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 oneDayCount = 0;
const oneFormattedDayCount = numberFormat.format(oneDayCount);

cardinalityForNumber(oneDayCount, locale).name;   // => "CARDINALITY_ONE"
strings.get("Delivery.LeadTime", {
  dayCount: oneDayCount,
  formattedDayCount: oneFormattedDayCount,
});   // => "0 usuku"

// CARDINALITY_OTHER
const otherDayCount = 2;
const otherFormattedDayCount = numberFormat.format(otherDayCount);

cardinalityForNumber(otherDayCount, locale).name;   // => "CARDINALITY_OTHER"
strings.get("Delivery.LeadTime", {
  dayCount: otherDayCount,
  formattedDayCount: otherFormattedDayCount,
});   // => "2 izinsuku"

Java

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

Locale locale = Locale.forLanguageTag("zu");

Strings strings = Strings.withFallbackLocale(locale)
  .localizedStringSupplier(() -> LocalizedStringLoader.loadFromFilesystem(Paths.get("strings")))
  .localeSupplier((matcher) -> matcher.bestMatchFor(locale))
  .build();

NumberFormat numberFormat = NumberFormat.getNumberInstance(locale);

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

// CARDINALITY_ONE
Number oneDayCount = 0;
String oneFormattedDayCount = numberFormat.format(oneDayCount);

assertEquals(Cardinality.ONE, Cardinality.forNumber(oneDayCount, locale));

// Expected: 0 usuku
assertEquals(oneFormattedDayCount + " usuku", strings.get(
  "Delivery.LeadTime", Map.of("dayCount", oneDayCount, "formattedDayCount", oneFormattedDayCount)
));

// CARDINALITY_OTHER
Number otherDayCount = 2;
String otherFormattedDayCount = numberFormat.format(otherDayCount);

assertEquals(Cardinality.OTHER, Cardinality.forNumber(otherDayCount, locale));

// Expected: 2 izinsuku
assertEquals(otherFormattedDayCount + " izinsuku", strings.get(
  "Delivery.LeadTime", Map.of("dayCount", otherDayCount, "formattedDayCount", otherFormattedDayCount)
));

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("zu")
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("0")
let category1 = try Cardinality.forNumber(number1, locale: locale.tag)
assert(category1 == .one)
// This fixed display value makes the translation assertion reproducible.
let display1 = "0"
let message1 = try strings.get("Delivery.LeadTime", placeholders: [
  "dayCount": .number(number1),
  "formattedDayCount": .text(display1),
])
assert(ExactString(message1) == ExactString("0 usuku"))

// CARDINALITY_OTHER
let number2 = try NumericValue.forDecimal("2")
let category2 = try Cardinality.forNumber(number2, locale: locale.tag)
assert(category2 == .other)
// This fixed display value makes the translation assertion reproducible.
let display2 = "2"
let message2 = try strings.get("Delivery.LeadTime", placeholders: [
  "dayCount": .number(number2),
  "formattedDayCount": .text(display2),
])
assert(ExactString(message2) == ExactString("2 izinsuku"))

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

const locale = "zu";

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_ONE range
const minDays = 0;
const formattedMinDays = numberFormat.format(minDays);
const maxDays = 1;
const formattedMaxDays = numberFormat.format(maxDays);
const formattedDayRange = formattedMinDays + "-" + formattedMaxDays;

cardinalityForRange(
  cardinalityForNumber(minDays, locale),
  cardinalityForNumber(maxDays, locale),
  locale
).name;   // => "CARDINALITY_ONE"
strings.get("Delivery.Window", { minDays, maxDays, formattedDayRange });   // => "0-1 usuku"

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.

Locale locale = Locale.forLanguageTag("zu");

Strings strings = Strings.withFallbackLocale(locale)
  .localizedStringSupplier(() -> LocalizedStringLoader.loadFromFilesystem(Paths.get("strings")))
  .localeSupplier((matcher) -> matcher.bestMatchFor(locale))
  .build();

NumberFormat numberFormat = NumberFormat.getNumberInstance(locale);

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

// CARDINALITY_ONE range
Number minDays = 0;
String formattedMinDays = numberFormat.format(minDays);
Number maxDays = 1;
String formattedMaxDays = numberFormat.format(maxDays);
String formattedDayRange = formattedMinDays + "-" + formattedMaxDays;

assertEquals(Cardinality.ONE, Cardinality.forRange(
  Cardinality.forNumber(minDays, locale),
  Cardinality.forNumber(maxDays, locale),
  locale
));

// Expected: 0-1 usuku
assertEquals(formattedDayRange + " usuku", strings.get(
  "Delivery.Window",
  Map.of("minDays", minDays, "maxDays", maxDays, "formattedDayRange", formattedDayRange)
));
