Cardinality example
This localized strings example uses complete, page-local CLDR minimal-pair patterns to demonstrate every cardinality category defined for the locale. Minimal-pair text contrasts grammatical forms; it is language-reference data, not reusable application copy.
Source: Unicode CLDR 48.2 ur locale data.
Sample localized strings file
{ "Cardinality.MinimalPair": { "commentary": "Demonstrates every CLDR cardinal category defined for this locale.", "translation": "{{cardinalityExample}}", "placeholders": { "cardinalityExample": { "value": "cardinalityValue", "translations": { "CARDINALITY_ONE": "{{formattedCardinalityValue}} گھنٹہ", "CARDINALITY_OTHER": "{{formattedCardinalityValue}} گھنٹے" } } } } }
Usage and expected results
JavaScript
The JavaScript code passes each raw number for cardinality selection and formats its display value separately with Intl.NumberFormat. For this right-to-left locale, the default bidiIsolation, "rtl-locales", wraps caller-supplied formatted values with U+2068 FIRST STRONG ISOLATE and U+2069 POP DIRECTIONAL ISOLATE; the expected strings below show those escapes.
import { cardinalityForNumber, createStrings } from "lokalized"; import { readStringsFromDirectory } from "lokalized/node"; const locale = "ur"; 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" // U+2068 FIRST STRONG ISOLATE begins bidirectional isolation around a caller-supplied value in right-to-left text // U+2069 POP DIRECTIONAL ISOLATE ends bidirectional isolation around a caller-supplied value in right-to-left text strings.get("Cardinality.MinimalPair", { cardinalityValue: oneCardinality, formattedCardinalityValue: oneFormattedCardinalityValue, }); // => "\u20681\u2069 گھنٹہ" // CARDINALITY_OTHER const otherCardinality = 0; const otherFormattedCardinalityValue = numberFormat.format(otherCardinality); cardinalityForNumber(otherCardinality, locale).name; // => "CARDINALITY_OTHER" strings.get("Cardinality.MinimalPair", { cardinalityValue: otherCardinality, formattedCardinalityValue: otherFormattedCardinalityValue, }); // => "\u20680\u2069 گھنٹے"
Java
The Java code passes each raw number for cardinality selection and formats its display value separately with NumberFormat. For this right-to-left locale, Lokalized's default BidiIsolation.RTL_LOCALES wraps caller-supplied formatted values with U+2068 FIRST STRONG ISOLATE and U+2069 POP DIRECTIONAL ISOLATE; the expected expressions below show those escapes.
Locale locale = Locale.forLanguageTag("ur"); 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 oneCardinality = 1; String oneFormattedCardinalityValue = numberFormat.format(oneCardinality); assertEquals(Cardinality.ONE, Cardinality.forNumber(oneCardinality, locale)); // Expected: <FSI>1<PDI> گھنٹہ // U+2068 FIRST STRONG ISOLATE begins bidirectional isolation around a caller-supplied value in right-to-left text // U+2069 POP DIRECTIONAL ISOLATE ends bidirectional isolation around a caller-supplied value in right-to-left text assertEquals("\u2068" + oneFormattedCardinalityValue + "\u2069 گھنٹہ", strings.get( "Cardinality.MinimalPair", Map.of("cardinalityValue", oneCardinality, "formattedCardinalityValue", oneFormattedCardinalityValue) )); // CARDINALITY_OTHER Number otherCardinality = 0; String otherFormattedCardinalityValue = numberFormat.format(otherCardinality); assertEquals(Cardinality.OTHER, Cardinality.forNumber(otherCardinality, locale)); // Expected: <FSI>0<PDI> گھنٹے assertEquals("\u2068" + otherFormattedCardinalityValue + "\u2069 گھنٹے", strings.get( "Cardinality.MinimalPair", Map.of( "cardinalityValue", otherCardinality, "formattedCardinalityValue", otherFormattedCardinalityValue ) ));
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("ur") 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("\u{2068}1\u{2069} گھنٹہ")) // CARDINALITY_OTHER let number2 = try NumericValue.forDecimal("0") let category2 = try Cardinality.forNumber(number2, locale: locale.tag) assert(category2 == .other) // This fixed display value makes the translation assertion reproducible. let display2 = "0" let message2 = try strings.get("Cardinality.MinimalPair", placeholders: [ "cardinalityValue": .number(number2), "formattedCardinalityValue": .text(display2), ]) assert(ExactString(message2) == ExactString("\u{2068}0\u{2069} گھنٹے"))
Cardinality Ranges
These are CLDR's explicit range mappings. For any start/end pair not listed, the range falls back to the ending cardinality.
-
CARDINALITY_ONE - CARDINALITY_OTHER
Matches
CARDINALITY_OTHER -
CARDINALITY_OTHER - CARDINALITY_ONE
Matches
CARDINALITY_OTHER -
CARDINALITY_OTHER - CARDINALITY_OTHER
Matches
CARDINALITY_OTHER
Ordinalities
All ordinal numbers use ORDINALITY_OTHER; no value selects a different form.
Example: دایاں موڑ نمبر 2 مڑیں۔.
