This works with a slight change (needs a quote / unquote cycle, not sure why):
defmodule DummyGettext do
defmacro dummy_macro(input, _lang \\ "en") do
# gettext macros require literals at this point (not within quote do … end block)
IO.inspect(input)
is_binary(input) == false && raise "gettext fail here"
end
def get_locales, do: ["en"]
end
defmodule MyLib.DSL do
defmacro __using__(_opts \\ []) do
quote do
import MyLib.DSL
require DummyGettext
def translated_input(input, locale \\ "en")
end
end
defmacro some_dsl(input) do
quote do
def translated_input(unquote(input), locale) do
DummyGettext.dummy_macro(unquote(input), locale)
end
end
end
end
defmodule MyApp.Example do
use MyLib.DSL
# this one obviously works
some_dsl "text to translate"
# my macros are fine with that, but gettext requires literal at compile time
# so below code fails
for data <- ["first", "second", "third"] do
some_dsl unquote(data)
end
end
There’s no need to create a function implementation per message / locale since gettext will already do that for you.
