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

Raises:

• (I18n::BadInflectionToken) —

  if a name of the token that alias points to is corrupted

• (I18n::BadInflectionAlias) —

  if an alias points to token that does not exists
