Method: I18n::Backend::Inflector#shorten_inflection_alias

Defined in:
lib/i18n-inflector/backend.rb

#shorten_inflection_alias(token, kind, locale) ⇒ Symbol (protected) #shorten_inflection_alias(token, kind, locale, subtree) ⇒ Symbol (protected)

Note:

It does take care of aliasing loops (max traverses is set to 64).

Resolves an alias for a token if the given token is an alias.

Overloads:

  • #shorten_inflection_alias(token, kind, locale) ⇒ Symbol
    Note:

    This version uses internal subtree and needs the translation data to be initialized.

    Resolves an alias for a token if the given token is an alias for the given locale and kind.

    Parameters:

    • token (Symbol) —

      the token name

    • kind (Symbol) —

      the kind of the given token

    • locale (Symbol) —

      the locale to use

    Returns:

    • (Symbol) —

      the true token that alias points to if the given token is an alias or the given token if it is a true token

  • #shorten_inflection_alias(token, kind, locale, subtree) ⇒ Symbol

    Resolves an alias for a token if the given token is an alias for the given locale and kind.

    Parameters:

    • token (Symbol) —

      the token name

    • kind (Symbol) —

      the kind of the given token

    • locale (Symbol) —

      the locale to use

    • subtree (Hash) —

      the tree (in a form of nested Hashes) containing inflection tokens to scan

    Returns:

    • (Symbol) —

      the true token that alias points to if the given token is an alias or the given token if it is a true token

Returns:

  • (Symbol) —

    the true token that alias points to if the given token is an alias or the given token if it is a true token
