Additional units aren't accessible

[kipcole9]

I was checking how to add new units to Cldr following the documentation but I failed.

I added two new units alarm and person, (the settings are listed below).

In iex I tried to get the new alarm unit, but it says it does not exist.
the unit gallon works fine, as in the example.

MyApp.Cldr.Unit.to_string Cldr.Unit.new!(:alarm, 1)
** (Cldr.UnknownUnitError) Unknown unit was detected at "alarm"
(ex_cldr_units 3.15.0) lib/cldr/unit.ex:1021: Cldr.Unit.new!/3
Exploring with iex, I manage to see that the new units are there:

iex> Citymonitor.Cldr.Unit.Additional.additional_units
[:alarm, :person]

iex> {:ok, dic_de} = Citymonitor.Cldr.Unit.unit_strings_for :de
iex> dic_de
%{
{"alarme", [:alarm]},
{"alarmen", [:alarm]},
...
}

iex> {:ok, dic_en} = Citymonitor.Cldr.Unit.unit_strings_for :en
iex> dic_en
%{
{"al.", [:alarm]},
{"alarm", [:alarm]},
...
}
I was wondering if the custom units should be merged into the core units,
but I don’t know how or where to do this:

Cldr.Unit.known_units() |> merge_base_units()

I would appreciate any hints or tips.

Here is the rest of the configuration.

iex> Citymonitor.Cldr.Unit.Additional.additional_units
[:alarm, :person]

Seems this is a result of a small bug in ex_cldr_units which I've now fixed. Would you please try configuring ex_cldr_units from GitHub to validate. You should only need to update your deps:

def deps do
  [
    {:ex_cldr_units, github: "elixir-cldr/cldr_units"},
    ...
  ]
end

I tested it and It works! Thank you so much.
