    Перечисление / Множественное число

    Как работает перечисление

    To use enumeration in Next.js Client Components, retrieve it via the useIntlayer hook. Here's an example:

    Настройка перечисления

    Чтобы настроить перечисление в вашем проекте Intlayer, необходимо создать модуль содержимого, включающий определения перечислений. Вот пример простого перечисления для количества автомобилей:

    **/*.content.ts
    import { enu, type Dictionary } from "intlayer";

const carEnumeration = {
  key: "car_count",
  content: {
    numberOfCar: enu({
      "<-1": "Меньше чем минус один автомобиль",
      "-1": "Минус один автомобиль",
      "0": "Нет автомобилей",
      "1": "Один автомобиль",
      ">5": "Несколько автомобилей",
      ">19": "Много автомобилей",
      "fallback": "Запасное значение", // Необязательно
    }),
  },
} satisfies Dictionary;

export default carEnumeration;

    В этом примере enu сопоставляет различные условия с конкретным содержимым. При использовании в React-компоненте Intlayer может автоматически выбирать соответствующее содержимое на основе переданной переменной.

    Порядок объявления важен в перечислениях Intlayer. Первое подходящее объявление будет выбрано. Если применяются несколько условий, убедитесь, что они расположены в правильном порядке, чтобы избежать непредвиденного поведения.
    Если запасное значение не объявлено, функция вернёт undefined, если ни один ключ не совпадает.

    Использование перечислений с React Intlayer

    To use enumeration in a React component, you can leverage the useIntlayer hook from the react-intlayer package. This hook retrieves the correct content based on the specified ID. Here's an example of how to use it:

    **/*.tsx
    import type { FC } from "react";
import { useIntlayer } from "react-intlayer";

const CarComponent: FC = () => {
  const { numberOfCar } = useIntlayer("car_count");

  return (
    <div>
      <p>
        {
          numberOfCar(0) // Output: No cars
        }
      </p>
      <p>
        {
          numberOfCar(6) // Output: Some cars
        }
      </p>
      <p>
        {
          numberOfCar(20) // Output: Many cars
        }
      </p>
      <p>
        {
          numberOfCar(0.01) // Output: Fallback value
        }
      </p>
    </div>
  );
};

    To use enumeration in Next.js Client Components, retrieve it via the useIntlayer hook. Here's an example:

    **/*.tsx
    "use client";

import type { FC } from "react";
import { useIntlayer } from "next-intlayer";

const CarComponent: FC = () => {
  const { numberOfCar } = useIntlayer("car_count");

  return (
    <div>
      <p>{numberOfCar(6)}</p>
    </div>
  );
};

export default CarComponent;

    To use enumeration in Vue components, retrieve it via the useIntlayer hook. Here's an example:

    **/*.vue
    <script setup lang="ts">
import { useIntlayer } from "vue-intlayer";

const { numberOfCar } = useIntlayer("car_count");
</script>

<template>
  <div>
    <p>{{ numberOfCar(6) }}</p>
  </div>
</template>

    To use enumeration in Svelte components, retrieve it via the useIntlayer hook. The store is accessed with $. Here's an example:

    **/*.svelte
    <script lang="ts">
import { useIntlayer } from "svelte-intlayer";

const content = useIntlayer("car_count");
</script>

<div>
  <p>{$content.numberOfCar(6)}</p>
</div>

    To use enumeration in Preact components, retrieve it via the useIntlayer hook. Here's an example:

    **/*.tsx
    import type { FC } from "preact";
import { useIntlayer } from "preact-intlayer";

const CarComponent: FC = () => {
  const { numberOfCar } = useIntlayer("car_count");

  return (
    <div>
      <p>{numberOfCar(6)}</p>
    </div>
  );
};

export default CarComponent;

    To use enumeration in SolidJS components, retrieve it via the useIntlayer hook. Here's an example:

    **/*.tsx
    import type { Component } from "solid-js";
import { useIntlayer } from "solid-intlayer";

const CarComponent: Component = () => {
  const { numberOfCar } = useIntlayer("car_count");

  return (
    <div>
      <p>{numberOfCar(6)}</p>
    </div>
  );
};

export default CarComponent;

    To use enumeration in Angular components, retrieve it via the useIntlayer hook. Here's an example:

    app.component.ts
    import { Component } from "@angular/core";
import { useIntlayer } from "angular-intlayer";

@Component({
  selector: "app-car",
  template: `
    <div>
      <p>{{ content().numberOfCar(6) }}</p>
    </div>
  `,
})
export class CarComponent {
  content = useIntlayer("car_count");
}

    To use enumeration with vanilla-intlayer, retrieve it via the useIntlayer hook. Here's an example:

    **/*.ts
    import { installIntlayer, useIntlayer } from "vanilla-intlayer";

installIntlayer();

const content = useIntlayer("car_count").onChange((newContent) => {
  document.getElementById("cars")!.textContent = newContent.numberOfCar(6);
});

// Initial render
document.getElementById("cars")!.textContent = content.numberOfCar(6);

    Combining Enumeration with Insert for Ordinal Numbers

    A common use case is displaying ordinal numbers (1st, 2nd, 3rd, etc.). You can combine enu with insert to create dynamic ordinal content:

    **/*.content.ts
    import { enu, insert, type Dictionary } from "intlayer";

const rankingContent = {
  key: "ranking_component",
  content: {
    ordinal: enu({
      1: insert("{{count}}st place"),
      2: insert("{{count}}nd place"),
      3: insert("{{count}}rd place"),
      fallback: insert("{{count}}th place"),
    }),
  },
} satisfies Dictionary;

export default rankingContent;

    Using Ordinal Enumeration

    To use this in a React component, call the enumeration with the last digit of the number to get the correct suffix, then pass the full count as the insertion value:

    **/*.tsx
    import type { FC } from "react";
import { useIntlayer } from "react-intlayer";

const RankingComponent: FC<{ count: number }> = ({ count }) => {
  const { ordinal } = useIntlayer("ranking_component");

  // Get the last digit to determine the correct suffix
  const lastDigit = Math.abs(count) % 10;

  return (
    <div>
      <p>
        {
          ordinal(lastDigit)({ count }) // e.g., "5th place" for count=5
        }
      </p>
    </div>
  );
};

    To use this in Next.js Client Components, call the enumeration with the last digit of the number to get the correct suffix, then pass the full count as the insertion value:

    **/*.tsx
    "use client";

import type { FC } from "react";
import { useIntlayer } from "next-intlayer";

const RankingComponent: FC<{ count: number }> = ({ count }) => {
  const { ordinal } = useIntlayer("ranking_component");
  const lastDigit = Math.abs(count) % 10;

  return (
    <div>
      <p>{ordinal(lastDigit)({ count })}</p>
    </div>
  );
};

export default RankingComponent;

    To use this in Vue components, call the enumeration with the last digit of the number to get the correct suffix, then pass the full count as the insertion value:

    **/*.vue
    <script setup lang="ts">
import { useIntlayer } from "vue-intlayer";

defineProps<{ count: number }>();

const { ordinal } = useIntlayer("ranking_component");
</script>

<template>
  <div>
    <p>{{ ordinal(Math.abs(count) % 10)({ count }) }}</p>
  </div>
</template>

    To use this in Svelte components, call the enumeration with the last digit of the number to get the correct suffix, then pass the full count as the insertion value:

    **/*.svelte
    <script lang="ts">
import { useIntlayer } from "svelte-intlayer";

export let count: number;

const content = useIntlayer("ranking_component");
$: lastDigit = Math.abs(count) % 10;
</script>

<div>
  <p>{$content.ordinal(lastDigit)({ count })}</p>
</div>

    To use this in Preact components, call the enumeration with the last digit of the number to get the correct suffix, then pass the full count as the insertion value:

    **/*.tsx
    import type { FC } from "preact";
import { useIntlayer } from "preact-intlayer";

const RankingComponent: FC<{ count: number }> = ({ count }) => {
  const { ordinal } = useIntlayer("ranking_component");
  const lastDigit = Math.abs(count) % 10;

  return (
    <div>
      <p>{ordinal(lastDigit)({ count })}</p>
    </div>
  );
};

export default RankingComponent;

    To use this in SolidJS components, call the enumeration with the last digit of the number to get the correct suffix, then pass the full count as the insertion value:

    **/*.tsx
    import type { Component } from "solid-js";
import { useIntlayer } from "solid-intlayer";

const RankingComponent: Component<{ count: number }> = (props) => {
  const { ordinal } = useIntlayer("ranking_component");

  return (
    <div>
      <p>{ordinal(Math.abs(props.count) % 10)({ count: props.count })}</p>
    </div>
  );
};

export default RankingComponent;

    To use this in Angular components, call the enumeration with the last digit of the number to get the correct suffix, then pass the full count as the insertion value:

    app.component.ts
    import { Component, Input } from "@angular/core";
import { useIntlayer } from "angular-intlayer";

@Component({
  selector: "app-ranking",
  template: `
    <div>
      <p>{{ content().ordinal(lastDigit())({ count }) }}</p>
    </div>
  `,
})
export class RankingComponent {
  @Input() count!: number;

  content = useIntlayer("ranking_component");

  lastDigit() {
    return Math.abs(this.count) % 10;
  }
}

    To use this with vanilla-intlayer, call the enumeration with the last digit of the number to get the correct suffix, then pass the full count as the insertion value:

    **/*.ts
    import { installIntlayer, useIntlayer } from "vanilla-intlayer";

installIntlayer();

const content = useIntlayer("ranking_component");
const lastDigit = Math.abs(5) % 10;

document.getElementById("ranking")!.textContent = content.ordinal(lastDigit)({
  count: 5,
});
