API

import { translator } from '@markuplint/i18n';

const t = translator({
  locale: 'ja',
  ...require('@markuplint/i18n/locales/ja.json'),
});

The translator function creates the t function. It is an overloading function that accepts kind of arguments below:

Translate sentence

type T = (template?: string, ...values: string[]) => string;
const message = t(
  // Template #1
  '{0} is {1:c}',
  // The {0} value of template #1
  t(
    // Template #2
    '{0} of {1}',
    // The {0} value of template #2
    t(
      // Template #3
      'the {0}',
      // The {0} value of template #3
      'value',
    ),
    // The {1} value of template #2
    t(
      // Template #4
      'the "{0*}" {1}',
      // The {0} value of template #4
      'id',
      // The {1} value of template #4
      'attribute',
    ),
  ),
  // The {1} value of template #1
  'duplicated',
);

console.log(message);
// => 属性「id」の値が重複しています

Placeholder

There is a placeholder that the number is surrounded by {} on template strings. It is replaced argument as a phrase. It translates the phrase if it matches the keyword defined in the dictionary.

Tagged templates syntax

⚠️ It is experimental.

import { taggedTemplateTranslator } from '@markuplint/i18n';

const _ = taggedTemplateTranslator({
  locale: 'ja',
  ...require('path/to/dictionary/ja.json'),
});

const message = _`${
  //
  _`${
    //
    _`the ${'value'}`
  } of ${
    //
    _`the "${'id'}" ${'attribute'}`
  }`
} is ${
  //
  'c:duplicated'
}`;

console.log(message);
// => 属性「id」の値が重複しています

Translate a phrase

type T = (phrase: string) => string;
const phrase = t('element');

console.log(phrase);
// => 要素

Translate listed phrases

type T = (phrases: string[]) => string;
const list = t(['element', 'attribute', 'value']);

console.log(list);
// => 「要素」「属性」「値」

/* If locale is "en" */
console.log(list);
// => "element", "attribute", "value"

It converts the character-separated list specified in each locale.

Locale Separator Before Char After Char
en , (comma + space) " (double quote) " (double quote)
ja none (empty string) (left corner bracket) (right corner bracket)

Avoid translation

The autocomplete is defined as オートコンプリート in the JA dictionary. However, It avoids translation if the number placeholder includes * (asterisk). It is an effective means if you want a code or a specific name.

const phrase = t('the "{0}" {1}', 'autocomplete', 'attribute');
console.log(phrase);
// => 属性「オートコンプリート」

const phrase = t('the "{0*}" {1}', 'autocomplete', 'attribute');
console.log(phrase);
// => 属性「autocomplete」

Another means is that it surrounds % (percentage) to a phrase. It is effective when you use listing.

const phrase = t('the "{0}" {1}', '%autocomplete%', 'attribute');
console.log(phrase);
// => 属性「autocomplete」

const list = t(['element', '%attribute%', 'value']);
console.log(list);
// => 「要素」「attribute」「値」
