Yes I saw it too.

Although I must admit that I took the opportunity to remove Timex from my project and replace it with Elixir native functions and modules.

The only thing missing was Timex.between? and that was easily resolved.

you can check the version of a dependency like Gettext that’s loaded at runtime using the Application.spec/2 function. Here’s how you can do it:

defmodule VersionCheck do
  def gettext_version do
    case Application.spec(:gettext, :vsn) do
      '0.26.0' -> :new_version
      _ -> :old_version
    end
  end
end

This function retrieves the version of Gettext and allows you to distinguish between different versions, enabling you to conditionally apply the necessary changes in your code.

@carlgleisner, you’ll still need to bring gettext/1 into scope by importing it - the message suggests it isn’t imported into that module. ie I don’t think the error is coming from ex_cldr in this case (but hey, wouldn’t be the first time I’ve been wrong!).

Somewhere you’ve got a module MyApp.Gettext. Then in MyAppWeb.Layouts there should be an import for MyApp.Gettext module I believe.

(thanks for the kind words)

if Version.match?(to_string(Application.spec(:app, :vsn)), ">= x.y.z") do

So you can do something like

if Version.match?(to_string(Application.spec(:gettet, :vsn), ">= 0.26") do
  use Gettext.Backend, otp_app: :my_app
else
  use Gettext, otp_app: :my_app
end

and then

if Version.match?(to_string(Application.spec(:gettet, :vsn), ">= 0.26") do
  use Gettext, backend: MyApp.Gettext
else
  import MyApp.Gettext
end
