@lingui/macro is a package that provides macros for internationalization (i18n) in JavaScript and React applications. It allows developers to mark strings for translation and handle pluralization, among other i18n tasks, in a way that integrates seamlessly with the LinguiJS framework.

What are @lingui/macro's main functionalities?

Translation

The `t` macro is used to mark strings for translation. This allows the string to be extracted and translated into different languages.

import { t } from '@lingui/macro';

const message = t`Hello, World!`;

Pluralization

The `plural` macro handles pluralization based on a count. It allows you to define different strings for singular and plural forms.

import { plural } from '@lingui/macro';

const message = plural(count, {
  one: '# book',
  other: '# books'
});

Select

The `select` macro is used for gender-based or other categorical selections. It allows you to define different strings based on the value of a variable.

import { select } from '@lingui/macro';

const message = select(gender, {
  male: 'He is a developer.',
  female: 'She is a developer.',
  other: 'They are a developer.'
});

Date and Time Formatting

The `date` macro formats dates according to the specified options. This is useful for displaying dates in a localized format.

import { date } from '@lingui/macro';

const message = date(new Date(), {
  year: 'numeric',
  month: 'long',
  day: 'numeric'
});
