v0.2.4

Patch Changes

• b762136: Add plural forms to the texts of custom templates.

  • A text in a template's messages may be plural forms instead of a string: one text per Intl.PluralRules category (zero, one, two, few, many, other), such as items: { one: '{count} item', other: '{count} items' }. other is required in en.
  • t('<name>.<key>', { count }) and t.html pick the form for count through the plural rules of the email's locale; {count} is the number formatted for the locale. A category without a form uses other. count is required at compile time for texts with plural forms.
  • Other locales of the template and the mailer's messages give plural forms for those keys category by category and may add categories the English texts leave out, such as few and many. Categories a locale leaves out fall back to English.
  • createMailer throws INVALID_CONFIG for plural forms without other in en, an unknown plural category, and a locale text whose form differs from en (a string where en has plural forms, or the other way round).
  • TemplateTexts and TemplateMessages accept plural forms. Translate and TemplateRenderContext take an optional second type parameter with the keys of texts with plural forms.
