    Enumeração / Pluralização

    Como a Enumeração Funciona

    No Intlayer, a enumeração é realizada através da função enu, que mapeia chaves específicas para seu conteúdo correspondente. Essas chaves podem representar valores numéricos, intervalos ou identificadores personalizados. Quando usada com React Intlayer ou Next Intlayer, o conteúdo apropriado é selecionado automaticamente com base na localidade da aplicação e nas regras definidas.

    Configurando a Enumeração

    Para configurar a enumeração no seu projeto Intlayer, você precisa criar um módulo de conteúdo que inclua definições de enumeração. Aqui está um exemplo de uma enumeração simples para o número de carros:

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

const carEnumeration = {
  key: "car_count",
  content: {
    numberOfCar: enu({
      "<-1": "Menos que menos um carro",
      "-1": "Menos um carro",
      "0": "Nenhum carro",
      "1": "Um carro",
      ">5": "Alguns carros",
      ">19": "Muitos carros",
      "fallback": "Valor padrão", // Opcional
    }),
  },
} satisfies Dictionary;

export default carEnumeration;

    Neste exemplo, enu mapeia várias condições para conteúdos específicos. Quando usado em um componente React, o Intlayer pode automaticamente escolher o conteúdo apropriado com base na variável fornecida.

    A ordem de declaração é importante nas enumerações do Intlayer. A primeira declaração válida é a que será selecionada. Se múltiplas condições se aplicarem, certifique-se de que estão ordenadas corretamente para evitar comportamentos inesperados.
    Se nenhum valor padrão (fallback) for declarado, a função retornará undefined caso nenhuma chave corresponda.

    Usando Enumeração com 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);

    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>
  );
};
