Specs

dgettext(
  term(),
  domain :: Macro.t(),

Specs

dgettext_noop(term(), domain :: String.t(), msgid :: String.t()) :: Macro.t()

Marks the given translation for extraction and returns it unchanged.

This macro can be used to mark a translation for extraction when mix gettext.extract is run. The return value is the given string, so that this macro can be used seamlessly in place of the string to extract.

Examples

MyApp.Gettext.dgettext_noop("errors", "Error found!")
#=> "Error found!"

my_fun = fn {msgid, msgid_plural} ->
  # do something with msgid and msgid_plural

Specs

gettext(term(), msgid :: String.t(), bindings :: Macro.t()) :: Macro.t()

Specs

gettext_comment(term(), comment :: String.t()) :: :ok

Stores an "extracted comment" for the next translation.

This macro can be used to add comments (Gettext refers to such comments as extracted comments) to the next translation that will be extracted. Extracted comments will be prefixed with #. in POT files.

Calling this function multiple times will accumulate the comments; when another Gettext macro (such as gettext/2) is called, the comments will be extracted and attached to that translation, and they will be flushed so as to start again.

This macro always returns :ok.

Examples

MyApp.Gettext.gettext_comment("The next translation is awesome")
MyApp.Gettext.gettext_comment("Another comment for the next translation")
MyApp.Gettext.gettext("The awesome translation")

Specs

gettext_noop(term(), msgid :: String.t()) :: Macro.t()

Specs

handle_missing_bindings(Gettext.MissingBindingsError.t(), binary()) ::
  binary() | no_return()

Default handling for missing bindings.

This function is called when there are missing bindings in a translation. It takes a Gettext.MissingBindingsError struct and the translation with the wrong bindings left as is with the %{} syntax.

For example, if something like this is called:

MyApp.Gettext.gettext("Hello %{name}, your favorite color is %{color}", name: "Jane", color: "blue")

and our it/LC_MESSAGES/default.po looks like this:

msgid "Hello %{name}, your favorite color is %{color}"
msgstr "Ciao %{name}, il tuo colore preferito è %{colour}" # (typo)

then Gettext will call:

MyApp.Gettext.handle_missing_bindings(exception, "Ciao Jane, il tuo colore preferito è %{colour}")

where exception is a struct that looks like this:

%Gettext.MissingBindingsError{
  backend: MyApp.Gettext,
  domain: "default",
  locale: "it",
  msgid: "Ciao %{name}, il tuo colore preferito è %{colour}",
  bindings: [:colour],
}

The return value of the handle_missing_bindings/2 callback is used as the translated string that the translation macros and functions return.

The default implementation for this function uses Logger.error/1 to warn about the missing binding and returns the translated message with the incomplete bindings.

This function can be overridden. For example, to raise when there are missing bindings:

def handle_missing_bindings(exception, _incomplete) do
  raise exception
end

Specs

handle_missing_plural_translation(
  Gettext.locale(),
  domain :: String.t(),
  msgid :: String.t(),
  msgid_plural :: String.t(),
  n :: non_neg_integer(),
  bindings :: map()
) ::
  {:ok, String.t()}
  | {:default, String.t()}
  | {:missing_bindings, String.t(), [atom()]}

Default handling for plural translations with a missing translation.

Same as handle_missing_translation/4, but for plural translations. In this case, n is the number used for pluralizing the translated string.

Specs

handle_missing_translation(
  Gettext.locale(),
  domain :: String.t(),
  msgid :: String.t(),
  bindings :: map()
) ::
  {:ok, String.t()}
  | {:default, String.t()}
  | {:missing_bindings, String.t(), [atom()]}

Default handling for translations with a missing translation.

When a Gettext function/macro is called with a string to translate into a locale but that locale doesn't provide a translation for that string, this callback is invoked. msgid is the string that Gettext tried to translate.

This function should return {:ok, translated} if a translation can be fetched or constructed for the given string. If you cannot find a translation, it should return {:default, translated}, where the translated string defaults to the interpolated msgid. You can, however, customize the default to, for example, pick the translation from the default locale. The important is to return :default instead of :ok whenever the result does not quite match the requested locale.
