Phoenix mix warning

Because the warning comes from elixir 1.7, supposedly (I haven’t seen this warning in elixir 1.6), and phoenix v1.3 was released before elixir 1.7.

The warning is about a keyword list in aliases in your mix.exs. If you check it, you’d see something like

defp aliases do
  [
    # ...
    "test":  #...
  ]
end

there.

The warning says that "test": can safely be replaced with test:.

I’ve removed the quotes from the atom but it still moans about the line… my guess is that it doesn’t like the other quoted “test” either, but I assume that is a command parameter that needs to be quoted?

  defp aliases do
    [
      "ecto.setup": ["ecto.create", "ecto.migrate", "run priv/repo/seeds.exs"],
      "ecto.reset": ["ecto.drop", "ecto.setup"],
      test: ["ecto.create --quiet", "ecto.migrate", "test"]
    ]
  end

No, the other "test" is supposed to be quoted and is not the reason for the warning. I don’t have any warnings once I replace "test": with test:.

FYI: The error (warning) eventually went away on its own - after about half a day of ignoring it!?!?

Is there a way to hide the warning without changing it?

Downgrading elixir to some version before the warning was introduced.

Lol, obviously I meant something other than that. But I guess that means it’s not possible. Thanks.

Well, warnings are printed to be acted on, there is currently no way to silence them besides changing the code accordingly or to change to a version of elixir that does not emit the warnings.

And I really hope, there will never be a way to silence the warnings, that would totally defeat their purpose.

I think I should be able to write :"something" without the compiler constantly throwing warning messages at me

Jokes aside, I don’t believe all warnings are equally important, especially in this case. There should be a way to tell the compiler “I know what I’m doing” so it can suppress specific warnings.

It also shows warnings when using :"..." inside an :ets.match - I don’t think you can write it in any other way there.
