Callbacks
compile_interpolate(translation_type, message, bindings)
View Source (since 0.19.0)@macrocallback compile_interpolate(translation_type(), message :: String.t(), bindings()) :: Macro.t()
Called to perform interpolation at compile time.
@callback message_format() :: String.t()
Defines the Gettext message format to be used when extracting.
The default interpolation module that ships with Gettext uses "elixir-format"
.
See the GNU Gettext documentation.
@callback runtime_interpolate(message :: String.t(), bindings()) :: {:ok, String.t()} | {:missing_bindings, partially_interpolated_message :: String.t(), missing_bindings :: [atom()]}
Called to perform interpolation at runtime.
If successful, should return {:ok, interpolated_string}
. If there
are missing bindings, should return {:missing_bindings, partially_interpolated, missing}
where partially_interpolated
is a string with the available bindings interpolated.
